down ﬁrmly and let antilock work for you. You might hear the antilock pump or motor operate, and feel the brake pedal pulsate, but this is normal. 4-5 Braking in Emergencies With ABS, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking. Panic Brake Assist Your vehicle has a Panic Brake Assist feature designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the Electronic Stability Control (ESC) hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The ESC hydraulic brake control module increases brake pressure at each corner of the vehicle until the Antilock Brake System (ABS) activates. Minor brake pedal pulsations or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The Panic Brake Assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased. Traction Control System (TCS) Your vehicle has a traction control system that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or more of the wheels are spinning or beginning to lose traction. When this happens, the system works the brakes and reduces engine power to limit wheel spin. This light ﬂashes while the traction control system is limiting wheel spin. You may feel or hear the system working, but this is normal. This light may also come on after extended heavy braking indicating the brakes have become too hot to limit wheel spin. 4-6 The traction control system automatically comes on whenever the vehicle is started. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud, ice, or snow and rocking the vehicle is required. See Rocking Your Vehicle to Get It Out on page 4-22. The traction control system can be turned off by pressing the traction control button, located next to the gear shift lever. When the traction control system is turned off, the traction control warning light on the instrument panel cluster comes on and TRACTION CONTROL OFF brieﬂy displays. The traction control system can be activated again by pressing the traction control button. While the traction control system is activated, the traction control system warning light on the instrument panel cluster comes on and TRACTION CONTROL ON brieﬂy displays. If the system is limiting wheel spin when you press the button, the traction control off light appears on the instrument panel cluster. The system will not turn off until there is no longer a current need to limit wheel spin. Turn the system back on by pressing the button again. If the light does not come on, traction control might not be working and your vehicle should be serviced by a dealer/retailer. Adding non-dealer/non-retailer accessories can affect your vehicle’s performance. See Accessories and Modiﬁcations on page 5-3 for more information. StabiliTrak® System Your vehicle has this feature. The StabiliTrak® system is an advanced computer controlled system that helps the driver maintain directional control of the vehicle in difficult driving conditions. This is accomplished by selectively applying any one of the vehicle’s brakes and reducing engine power. The StabiliTrak® system comes on automatically whenever you start your vehicle. 4-7 The STABILITRAK NOT READY message may be displayed in the DIC and the traction control system and StabiliTrak® warning light on the instrument panel cluster will be on after ﬁrst driving the vehicle and exceeding 30 mph 48 (km/h) for 30 seconds. The StabiliTrak® system is off until the light has turned off. This could take up to 15 minutes. See DIC Warnings and Messages on page 3-52 for more information. The traction control system and StabiliTrak® warning light on the instrument panel cluster will ﬂash when the system is operating. You may also feel or hear the system working. This is normal. This light may also come on after extended heavy braking indicating the brakes have become too hot to limit wheel spin. StabiliTrak® can be turned off using the traction control button. To disable StabiliTrak®, press and hold the traction control button for ﬁve seconds. StabiliTrak® can be activated again by pressing the traction control button. The SERVICE STABILITRAK message will be displayed and the traction control system and StabiliTrak® warning light on the instrument panel cluster will come on if there is a problem with the system. When this light and the SERVICE STABILITRAK message are on, the system is not operational. Adjust your driving accordingly. 4-8 All-Wheel Drive (AWD) System If your vehicle has all-wheel drive (AWD), the AWD system operates automatically without any action required by the driver. If the front drive wheels begin to slip, the rear wheels will automatically begin to drive the vehicle as required. Torque is also applied to the rear wheels during launches. There may be a slight engagement noise during hard use but this is normal. This light is located on the instrument panel cluster. This light and the SERVICE ALL WHEEL DRIVE message in the DIC will come on and stay on to indicate there may be a problem with the drive system and service is required. See Service All-Wheel Drive Light on page 3-42 and DIC Warnings and Messages on page 3-52 for more information. This light will come on along with the ALL WHEEL DRIVE OFF message when the rear drive system is overheating. This light will turn off when the rear drive system cools down. If this light stays on, it must be reset. To reset the light, turn the ignition off and then back on again. If the light stays on, see your dealer/retailer for service. See DIC Warnings and Messages on page 3-52 for more information. Steering Electric Power Steering (3.4L V6 Engine) If the engine stalls while you are driving, the power steering assist system will continue to operate until you are able to stop your vehicle. If you lose power steering assist because the electric power steering system is not functioning, you can steer, but it will take more effort. If you turn the steering wheel in either direction several times until it stops, or hold the steering wheel in the stopped position for an extended amount of time, you may notice a reduced amount of power steering assist. The normal amount of power steering assist should return shortly after a few normal steering movements. The electric power steering system does not require regular maintenance. If you suspect steering system problems, such as abnormally high steering effort for a prolonged period of time, contact your dealer/retailer for service repairs. Hydraulic Power Steering (3.6L V6 Engine) If you lose power steering assist because the engine stops or the power steering system is not functioning, you can steer, but it will take much more effort. 4-9 What should you do if this ever happens? Ease up on the brake or accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions. Under less favorable conditions you will want to go slower. If you need to reduce your speed as you approach a curve, do it before you enter the curve, while the front wheels are straight ahead. Try to adjust your speed so you can drive through the curve. Maintain a reasonable, steady speed. Wait to accelerate until you are out of the curve, and then accelerate gently into the straightaway. Adding non-dealer/non-retailer accessories can affect your vehicle’s performance. See Accessories and Modiﬁcations on page 5-3. Steering Tips It is important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here is why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels. If there is no traction, inertia will keep the vehicle going in the same direction. If you have ever tried to steer a vehicle on wet ice, you will understand this. The traction you can get in a curve depends on the condition of the tires and the road surface, the angle at which the curve is banked, and your speed. While you are in a curve, speed is the one factor you can control. Suppose you are steering through a sharp curve. Then you suddenly accelerate. Both control systems — steering and acceleration — have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. See Traction Control System (TCS) on page 4-6 and StabiliTrak® System on page 4-7. 4-10 Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and ﬁnd a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. You can avoid these problems by braking — if you can stop in time. But sometimes you cannot; there is not room. That is the time for evasive action — steering around the problem. Your vehicle can perform very well in emergencies like these. First apply the brakes. See Braking on page 4-4. It is better to remove as much speed as you can from a possible collision. Then steer around the problem, to the left or right depending on the space available. An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object. The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly. 4-11 Off-Road Recovery You may ﬁnd that your vehicle’s right wheels have dropped off the edge of a road onto the shoulder while you are driving. Passing Passing another vehicle on a two-lane road can be dangerous. To reduce the risk of danger while passing, we suggest the following tips: Look down the road, to the sides, and to crossroads for situations that might affect a successful pass. If in doubt, wait. (cid:127) Watch for traffic signs, pavement markings, and lines that could indicate a turn or an intersection. Never cross a solid or double-solid line on your side of the lane. (cid:127) Do not get too close to the vehicle you want to pass. Doing so can reduce your visibility. (cid:127) Wait your turn to pass a slow vehicle. (cid:127) When you are being passed, ease to the right. Loss of Control Let us review what driving experts say about what happens when the three control systems — brakes, steering, and acceleration — do not have enough friction where the tires meet the road to do what the driver has asked. In any emergency, do not give up. Keep trying to steer and constantly seek an escape route or area of less danger. If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy. Ease off the accelerator and then, if there is nothing in the way, steer so that your vehicle straddles the edge of the pavement. You can turn the steering wheel up to one-quarter turn until the right front tire contacts the pavement edge. Then turn the steering wheel to go straight down the roadway. 4-12 (cid:127) Skidding In a skid, a driver can lose control of the vehicle. Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. The three types of skids correspond to your vehicle’s three control systems. In the braking skid, the wheels are not rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force. And in the acceleration skid, too much throttle causes the driving wheels to spin. A cornering skid is best handled by easing your foot off the accelerator pedal. Remember: Any traction control system helps avoid only the acceleration skid. If your traction system is off, then an acceleration skid is also best handled by easing your foot off the accelerator pedal. See Traction Control System (TCS) on page 4-6 and StabiliTrak® System on page 4-7. If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel, or other material is on the road. For safety, you will want to slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance will be longer and vehicle control more limited. While driving on a surface with reduced traction, try your best to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide. You may not realize the surface is slippery until your vehicle is skidding. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt. Remember: Any Antilock Brake System (ABS) helps avoid only the braking skid. 4-13 Driving at Night Night driving is more dangerous than day driving because some drivers are likely to be impaired — by alcohol or drugs, with night vision problems, or by fatigue. Night driving tips include: (cid:127) Drive defensively. (cid:127) Do not drink and drive. (cid:127) Reduce headlamp glare by adjusting the inside rearview mirror. (cid:127) Slow down and keep more space between you and other vehicles because your headlamps can only light up so much road ahead. (cid:127) Watch for animals. (cid:127) When tired, pull off the road. (cid:127) Do not wear sunglasses. (cid:127) Avoid staring directly into approaching headlamps. (cid:127) Keep the windshield and all glass on your vehicle clean — inside and out. (cid:127) Keep your eyes moving, especially during turns or curves. No one can see as well at night as in the daytime. But, as we get older, these differences increase. A 50-year-old driver might need at least twice as much light to see the same thing at night as a 20-year-old. 4-14 Driving in Rain and on Wet Roads Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or ﬂowing water. {CAUTION: Wet brakes can cause crashes. They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally. CAUTION: (Continued) CAUTION: (Continued) Flowing or rushing water creates strong forces. Driving through ﬂowing water could cause your vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through ﬂowing water. Hydroplaning Hydroplaning is dangerous. Water can build up under your vehicle’s tires so they actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet. 4-15 Other Rainy Weather Tips Besides slowing down, other wet weather driving tips include: (cid:127) Allow extra following distance. (cid:127) Pass with caution. (cid:127) Keep windshield wiping equipment in good shape. (cid:127) Keep the windshield washer ﬂuid reservoir ﬁlled. (cid:127) Have good tires with proper tread depth. See Tires on page 5-52. Before Leaving on a Long Trip To prepare your vehicle for a long trip, consider having it serviced by your dealer/retailer before departing. Things to check on your own include: (cid:127) Windshield Washer Fluid: Reservoir full? Windows clean — inside and outside? (cid:127) Wiper Blades: In good shape? Fuel, Engine Oil, Other Fluids: All levels checked? Lamps: Do they all work and are lenses clean? Tires: Are treads good? Are tires inﬂated to recommended pressure? (cid:127) Weather and Maps: Safe to travel? Have up-to-date maps? Highway Hypnosis Always be alert and pay attention to your surroundings while driving. If you become tired or sleepy, ﬁnd a safe place to park your vehicle and rest. Other driving tips include: (cid:127) Keep the vehicle well ventilated. (cid:127) Keep interior temperature cool. (cid:127) Keep your eyes moving — scan the road ahead and to the sides. (cid:127) Check the rearview mirror and vehicle instruments often. 4-16 (cid:127) (cid:127) (cid:127) Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on ﬂat or rolling terrain. Tips for driving in these conditions include: (cid:127) Keep your vehicle serviced and in good shape. (cid:127) Check all ﬂuid levels and brakes, tires, cooling system, and transmission. (cid:127) Going down steep or long hills, shift to a lower gear. {CAUTION: If you do not shift down, the brakes could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let the engine assist the brakes on a steep downhill slope. {CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. The brakes will have to do all the work of slowing down and they could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Always have the engine running and your vehicle in gear when you go downhill. (cid:127) Stay in your own lane. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane. Top of hills: Be alert — something could be in your lane (stalled car, accident). (cid:127) Pay attention to special road signs (falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action. 4-17 (cid:127) Winter Driving Here are some tips for winter driving: (cid:127) Have your vehicle in good shape for winter. (cid:127) You might want to put winter emergency supplies in your vehicle. Include an ice scraper, a small brush or broom, a supply of windshield washer ﬂuid, a rag, some winter outer clothing, a small shovel, a ﬂashlight, a red cloth, and a couple of reﬂective warning triangles. And, if you will be driving under severe conditions, include a small bag of sand, a piece of old carpet, or a couple of burlap bags to help provide traction. Be sure you properly secure these items in your vehicle. Also see Tires on page 5-52. Driving on Snow or Ice Most of the time, those places where the tires meet the road probably have good traction. However, if there is snow or ice between the tires and the road, you can have a very slippery situation. You have a lot less traction, or grip, and need to be very careful. 4-18 What is the worst time for this? Wet ice. Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it can offer the least traction of all. You can get wet ice when it is about freezing, 32°F (0°C), and freezing rain begins to fall. Try to avoid driving on wet ice until salt and sand crews can get there. Whatever the condition — smooth ice, packed, blowing, or loose snow — drive with caution. Traction control improves your ability to accelerate when driving on a slippery road. But you can turn the traction system off if you ever need to. You should turn the traction system off if your vehicle ever gets stuck in sand, mud, ice, or snow. See If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-21. Even though your vehicle has a traction system, slow down and adjust your driving to the road conditions. Under certain conditions, you might want to turn the traction system off, such as when driving through deep snow and loose gravel, to help maintain vehicle motion at lower speeds. See Traction Control System (TCS) on page 4-6 and StabiliTrak® System on page 4-7. The Antilock Brake System (ABS) improves your vehicle’s stability when you make a hard stop on a slippery road. Even though you have ABS, begin stopping sooner than you would on dry pavement. See Antilock Brake System (ABS) on page 4-5. (cid:127) Allow greater following distance on any slippery road. (cid:127) Watch for slippery spots. The road might be ﬁne until you hit a spot that is covered with ice. On an otherwise clear road, ice patches can appear in shaded areas where the sun cannot reach, such as around clumps of trees, behind buildings, or under bridges. Sometimes the surface of a curve or an overpass can remain icy when the surrounding roads are clear. If you see a patch of ice ahead of you, brake before you are on it. Try not to brake while you are actually on the ice, and avoid sudden steering maneuvers. If You Are Caught in a Blizzard If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: Turn on the hazard warning ﬂashers. Tie a red cloth to your vehicle to alert police that you have been stopped by the snow. (cid:127) Put on extra clothing or wrap a blanket around you. If you do not have blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, ﬂoor mats — anything you can wrap around yourself or tuck under your clothing to keep warm. 4-19 (cid:127) (cid:127) {CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You cannot see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking the exhaust pipe. And check around again from time to time to be sure snow does not collect there. Open a window just a little on the side of the vehicle that is away from the wind. This will help keep CO out. Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery charged. You will need a well-charged battery to restart the vehicle, and possibly for signaling later on with the headlamps. Let the heater run for a while. You can run the engine to keep warm, but be careful. 4-20 Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes. If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow Slowly and cautiously spin the wheels to free your vehicle when stuck in sand, mud, ice, or snow. See Rocking Your Vehicle to Get It Out on page 4-22. If your vehicle has a traction system, it can often help to free a stuck vehicle. Refer to your vehicle’s traction system in the Index. If the stuck condition is too severe for the traction system to free the vehicle, turn the traction system off and use the rocking method. {CAUTION: If you let your vehicle’s tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment ﬁre or other damage. Spin the wheels as little as possible and avoid going above 35 mph (55 km/h) as shown on the speedometer. For information about using tire chains on your vehicle, see Tire Chains on page 5-75. 4-21 Rocking Your Vehicle to Get It Out First, turn the steering wheel left and right to clear the area around the front wheels. Turn off any traction or stability system. See Traction Control System (TCS) on page 4-6 and StabiliTrak® System on page 4-7. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. By slowly spinning the wheels in the forward and reverse directions, you will cause a rocking motion that could free your vehicle. If that does not get your vehicle out after a few tries, it might need to be towed out. If your vehicle does need to be towed out, see Towing Your Vehicle on page 4-27. Loading Your Vehicle It is very important to know how much weight your vehicle can carry. Two labels on your vehicle show how much weight it may properly carry, the Tire and Loading Information label and the Vehicle Certiﬁcation label. {CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle. 4-22 Tire and Loading Information Label Label Example A vehicle speciﬁc Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar). With the driver’s door open, you will ﬁnd the label attached below the door lock post (striker). The tire and loading information label lists the number of occupant seating positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds. The vehicle capacity weight includes the weight of all occupants, cargo, and all nonfactory-installed options. The Tire and Loading Information label also lists the tire size of the original equipment tires (C) and the recommended cold tire inﬂation pressures (D). For more information on tires and inﬂation, see Tires on page 5-52 and Inﬂation - Tire Pressure on page 5-59. There is also important loading information on the Certiﬁcation/Tire label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axles. See “Certiﬁcation/Tire Label” later in this section. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. 4-23 4. The resulting ﬁgure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs and there will be ﬁve 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 − 750 (5 x 150) = 650 lbs). 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, the load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity for your vehicle. If your vehicle can tow a trailer, see Towing a Trailer on page 4-32 for important information on towing a trailer, towing safety rules, and trailering tips. 4-24 Example 1 Item Description Maximum Vehicle Capacity Weight for Example 1 = Subtract Occupant Weight 150 lbs (68 kg) × 2 = Available Occupant and Cargo Weight = Total 1,000 lbs (453 kg) 300 lbs (136 kg) 700 lbs (317 kg) Example 2 Example 3 Item Description Maximum Vehicle Capacity Weight for Example 2 = Subtract Occupant Weight 150 lbs (68 kg) × 5 = Available Cargo Weight = Total Item 1,000 lbs (453 kg) 750 lbs (340 kg) 250 lbs (113 kg) Description Maximum Vehicle Capacity Weight for Example 3 = Subtract Occupant Weight 200 lbs (91 kg) × 5 = Available Cargo Weight = Total 1,000 lbs (453 kg) 1,000 lbs (453 kg) 0 lbs (0 kg) Refer to your vehicle’s tire and loading information label for speciﬁc information about your vehicle’s maximum vehicle capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed your vehicle’s maximum vehicle capacity weight. 4-25 Certiﬁcation Label A vehicle speciﬁc Certiﬁcation/Tire label is found on the rear edge of the driver’s door, or on the vehicle’s center pillar (B-pillar). The label shows the size of your original tires and the inﬂation pressures needed to obtain the gross weight capacity of your vehicle. This is called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel, and cargo. 4-26 The Certiﬁcation/Tire label also tells you the maximum weights for the front and rear axles, called the Gross Axle Weight Rating (GAWR). To ﬁnd out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle or the GAWR for either the front or rear axle. {CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle. Notice: Overloading your vehicle may cause damage. Repairs would not be covered by your warranty. Do not overload your vehicle. If you put things inside your vehicle — like suitcases, tools, packages, or anything else — they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going. {CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. (cid:127) Put things in the cargo area of your vehicle. Try to spread the weight evenly. (cid:127) Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. (cid:127) Do not leave an unsecured child restraint in your vehicle. (cid:127) When you carry something inside the vehicle, secure it whenever you can. (cid:127) Do not leave a seat folded down unless you need to. Towing Towing Your Vehicle Consult your dealer/retailer or a professional towing service if you need to have your disabled vehicle towed. See Roadside Assistance Program on page 7-7. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see “Recreational Vehicle Towing” following. Recreational Vehicle Towing Recreational vehicle towing means towing your vehicle behind another vehicle – such as behind a motorhome. The two most common types of recreational vehicle towing are known as “dinghy towing” (towing your vehicle with all four wheels on the ground) and “dolly towing” (towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”). With the proper preparation and equipment, many vehicles can be towed in these ways. See “Dinghy Towing” and “Dolly Towing,” following. 4-27 Here are some important things to consider before you do recreational vehicle towing: (cid:127) What’s the towing capacity of the towing vehicle? Be sure you read the tow vehicle manufacturer’s recommendations. (cid:127) How far will you tow? Some vehicles have restrictions on how far and how long they can tow. (cid:127) Do you have the proper towing equipment? See your dealer/retailer or trailering professional for additional advice and equipment recommendations. Is your vehicle ready to be towed? Just as you would prepare your vehicle for a long trip, you’ll want to make sure your vehicle is prepared to be towed. See Before Leaving on a Long Trip on page 4-16. Dinghy Towing (Vehicles with 5-speed Transmission) Notice: Towing an all-wheel-drive vehicle with all four wheels on the ground, or even with only two of its wheels on the ground, will damage drivetrain components. Do not tow an all-wheel-drive vehicle if any of its wheels will be on the ground. Your vehicle was not designed to be towed with all of its wheels on the ground. If you have a two-wheel-drive vehicle, it can be towed with two of its wheels on the ground. See “Dolly Towing” following. If you have an all-wheel-drive vehicle, it cannot be towed with any of its wheels on the ground. It can be towed with the car carrier equipment. Dinghy Towing (Vehicles with 6-speed Transmission) If you have a front-wheel-drive vehicle, it can be dinghy towed from the front. These vehicles may also be towed by putting the front wheels on a dolly. See “Dolly Towing” later in this section. If you have an all-wheel-drive vehicle, it can be dinghy towed from the front. You can also tow these vehicles by placing them on a platform trailer with all four wheels off of the ground. These vehicles cannot be towed using a dolly. For vehicles being dinghy towed, the vehicle should be run at the beginning of each day and at each RV fuel stop for about ﬁve minutes. This will ensure proper lubrication of transmission components. Re-connect the vehicle’s battery to start the vehicle. 4-28 (cid:127) If you exceed 65 mph (105 km/h) while If you tow your vehicle without performing Notice: each of the steps listed under “Dinghy Towing,” you could damage the automatic transmission. Be sure to follow all steps of the dinghy towing procedure prior to and after towing your vehicle. Notice: towing your vehicle, it could be damaged. Never exceed 65 mph (105 km/h) while towing your vehicle. Once you have reached your destination: 1. Set the parking brake. 2. Put the vehicle in PARK (P). 3. Re-connect the vehicle’s battery. Contact your dealer/retailer for more information on the battery connection procedure. 4. Turn the ignition key to LOCK/OFF and remove the key from the ignition. Notice: Don’t tow a vehicle with the front drive wheels on the ground if one of the front tires is a compact spare tire. Towing with two different tire sizes on the front of the vehicle can cause severe damage to the transmission. 4-29 To tow your vehicle from the front with all four wheels on the ground: 1. Position the vehicle to tow and then secure it. 2. Turn the ignition to LOCK/OFF. 3. Set the parking brake. 4. Turn the ignition to ACC/ACCESSORY. 5. Shift your transmission to NEUTRAL (N). 6. To prevent your battery from draining while the vehicle is being towed, disconnect the vehicle’s battery. Contact your dealer/retailer for more information on the battery disconnection procedure. 7. Release the parking brake. Dolly Towing (Vehicles with 5-speed Transmission) If you have a two-wheel-drive vehicle, it can be towed with two of its wheels on the ground. To dolly tow your vehicle: 1. Put the front wheels on a dolly. 2. Put the vehicle in PARK (P). 3. Set the parking brake and then remove the key. 4. Clamp the steering wheel in a straight-ahead position with a clamping device designed for towing. 5. Release the parking brake. Notice: Towing an all-wheel-drive vehicle with all four wheels on the ground, or even with only two of its wheels on the ground, will damage drivetrain components. Do not tow an all-wheel-drive vehicle if any of its wheels will be on the ground. If you have an all-wheel-drive vehicle, it cannot be towed with any of its wheels on the ground. It can be towed with car carrier equipment. 4-30 Dolly Towing (All-Wheel-Drive Vehicles with 6-speed Transmission) All-wheel-drive vehicles must not be towed with two wheels on the ground. To properly tow these vehicles, they should be placed on a platform trailer with all four wheels off of the ground or dinghy towed from the front. Dolly Towing (Front-Wheel-Drive Vehicles with 6-speed Transmission) Towing Your Vehicle From the Rear To tow your front-wheel-drive vehicle from the front with two wheels on the ground: 1. Put the front wheels on a dolly. 2. Move the shift lever to PARK (P). 3. Set the parking brake and then remove the key. 4. Clamp the steering wheel in a straight-ahead position with a clamping device designed for towing. 5. Release the parking brake. Notice: Towing your vehicle from the rear could damage it. Also, repairs would not be covered by the warranty. Never have your vehicle towed from the rear. Do not tow your vehicle from the rear. 4-31 Towing a Trailer {CAUTION: If you do not use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well — or even at all. You and your passengers could be seriously injured. You may also damage your vehicle; the resulting repairs would not be covered by your warranty. Pull a trailer only if you have followed all the steps in this section. Ask your dealer/retailer for advice and information about towing a trailer with your vehicle. Notice: Pulling a trailer improperly can damage your vehicle and result in costly repairs that would not be covered by your warranty. Always follow the instructions in this section and check with your dealer/retailer for more information about towing a trailer with your vehicle. To identify the trailering capacity of your vehicle, you should read the information in “Weight of the Trailer” that appears later in this section. Trailering is different than just driving your vehicle by itself. Trailering means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. That is the reason for this section. In it are many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. So please read this section carefully before you pull a trailer. 4-32 If You Do Decide To Pull A Trailer If you do, here are some important points: There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you will be driving. A good source for this information can be state or provincial police. (cid:127) Consider using a sway control. See “Hitches” later in this section. (cid:127) Do not tow a trailer at all during the ﬁrst 500 miles (800 km) your new vehicle is driven. Your engine, axle or other parts could be damaged. (cid:127) During the ﬁrst 500 miles (800 km) that you tow a trailer, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads. Three important considerations have to do with weight: (cid:127) Weight of the trailer (cid:127) Weight of the trailer tongue (cid:127) Weight on your vehicle’s tires Weight of the Trailer How heavy can a trailer safely be? Your vehicle can tow up to 3,500 lbs (1 575 kg). But even that can be too heavy. It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. It can also depend on any special equipment that you have on your vehicle, and the amount of tongue weight the vehicle can carry. See “Weight of the Trailer Tongue” later in this section for more information. Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers and cargo in the tow vehicle must be subtracted from the maximum trailer weight. Ask your dealer/retailer for our trailering information or advice, or write us at our Customer Assistance Offices. See Customer Assistance Offices on page 7-5 for more information. 4-33 (cid:127) Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. If you have a lot of options, passengers, or cargo in the vehicle, it will reduce the tongue weight your vehicle can carry, which will also reduce the trailer weight your vehicle can tow. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See Loading Your Vehicle on page 4-22 for more information about your vehicle’s maximum load capacity. 4-34 If you are using a weight-carrying or a weight-distributing hitch, the trailer tongue weight (A) should be 10 percent to 15 percent of the total loaded trailer weight (B). Do not exceed the maximum allowable tongue weight for your vehicle. After you have loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, you may be able to get them right simply by moving some items around in the trailer. Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inﬂated to the upper limit for cold tires. You will ﬁnd these numbers on the Certiﬁcation/Tire Label at the rear edge of the driver’s door, or see Loading Your Vehicle on page 4-22. Then be sure you do not go over the GVW limit for your vehicle, including the weight of the trailer tongue. Hitches It is important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you will need the right hitch. Here are some rules to follow: If you will be pulling a trailer that, when loaded, will weigh more than 2,000 lbs (900 kg), be sure to use a properly mounted, weight-carrying hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when you’re driving. (cid:127) Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, remember to seal the holes when you remove the hitch. If you do not seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 2-36. Dirt and water can, too. Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. Never allow safety chains to drag on the ground. Trailer Brakes If your trailer weighs more than 1,000 lbs (450 kg) loaded, then it needs its own brakes – and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you will be able to install, adjust and maintain them properly. Because your vehicle may have anti-lock brakes, do not try to tap into your vehicle’s brake system. If you do, both brake systems will not work well, or at all. 4-35 (cid:127) Towing a trailer requires a certain amount of experience. Before setting out for the open road, you will want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself. Before you start, check all trailer hitch parts and attachments, safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working. Driving with a Trailer {CAUTION: If you have the liftgate open and you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You cannot see or smell CO. It can cause unconsciousness or death. See Engine Exhaust on page 2-36. To maximize your safety when towing a trailer: (cid:127) Have your exhaust system inspected for leaks, and make necessary repairs before starting on your trip. (cid:127) Keep the liftgate closed. If exhaust does come into your vehicle through a window in the rear or another opening, drive with your front, main heating or cooling system on and with the fan on any speed. This will bring fresh, outside air into your vehicle. Do not use the climate control setting for maximum air because it only recirculates the air inside your vehicle. See Climate Control System on page 3-20. 4-36 (cid:127) Electronic Trailer Sway Control Electronic Trailer Sway Control is integrated into the StabiliTrak® system of your vehicle. This feature detects the occurrence of trailer sway that may be caused by improper trailer weight balance, or excessive vehicle speed. When the system detects trailer sway, the StabiliTrak® system may begin to apply the front brakes, without you pressing the brake pedal, to help you in stabilizing the vehicle. The StabiliTrak® warning light will ﬂash to indicate that you should reduce vehicle speed. If the trailer sway continues, StabiliTrak® will reduce engine torque as a method to reduce the speed of the vehicle. Reducing the speed of the vehicle is necessary to reduce trailer sway. Electronic Trailer Sway Control is de-activated when StabiliTrak® is turned off, and is re-activated when it is turned back on. See StabiliTrak® System on page 4-7. Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns. Passing You will need more passing distance up ahead when you are towing a trailer. And, because you are a good deal longer, you will need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns Notice: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering. When you are turning with a trailer, make wider turns than normal. Do this so your trailer will not strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. 4-37 Turn Signals When Towing a Trailer When you tow a trailer, your vehicle has to have extra wiring. The arrows on your instrument panel will ﬂash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also ﬂash, telling other drivers you are about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will ﬂash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you do not shift down, you might have to use your brakes so much that they would get hot and no longer work well. If you are towing a trailer that weighs more than 1,000 lbs (450 kg), drive in INTERMEDIATE (I) instead of DRIVE (D) or, as you need to, a lower gear. This will minimize heat build-up and extend the life of your transmission. Parking on Hills {CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, do the following: 1. Apply your regular brakes, but do not shift into PARK (P) yet. 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. 4. Reapply the regular brakes. Then apply your parking brake, and then shift to PARK (P). 5. Release the regular brakes. 4-38 When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you do the following: (cid:127) Start your engine. (cid:127) Shift into a gear. (cid:127) Release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When Trailer Towing Your vehicle will need service more often when you are pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transmission ﬂuid, engine oil, belts, cooling system and brake system. Each of these is covered in this manual, and the Index will help you ﬁnd them quickly. If you are trailering, it is a good idea to review these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight. 4-39 ✍ NOTES 4-40 Section 5 Service and Appearance Care Service ............................................................5-3 Accessories and Modiﬁcations ..........................5-3 California Proposition 65 Warning .....................5-4 California Perchlorate Materials Requirements .....5-4 Doing Your Own Service Work .........................5-4 Adding Equipment to the Outside of Your Vehicle ..............................................5-5 Fuel ................................................................5-5 Gasoline Octane ............................................5-5 Gasoline Speciﬁcations ....................................5-6 California Fuel ...............................................5-6 Additives .......................................................5-6 Fuels in Foreign Countries ...............................5-7 Filling the Tank ..............................................5-8 Filling a Portable Fuel Container .....................5-10 Checking Things Under the Hood ....................5-10 Hood Release ..............................................5-11 Engine Compartment Overview .......................5-12 Engine Oil ...................................................5-15 Engine Oil Life System ..................................5-18 Engine Air Cleaner/Filter ................................5-20 Automatic Transmission Fluid .........................5-22 Engine Coolant .............................................5-22 Engine Overheating .......................................5-25 Overheated Engine Protection Operating Mode ........................................5-26 Cooling System ............................................5-27 Power Steering Fluid .....................................5-32 Windshield Washer Fluid ................................5-33 Brakes ........................................................5-34 Battery ........................................................5-37 Jump Starting ...............................................5-38 All-Wheel Drive ..............................................5-44 Headlamp Aiming ...........................................5-46 Bulb Replacement ..........................................5-47 Halogen Bulbs ..............................................5-47 Headlamps, Front Turn Signal, Sidemarker, and Parking Lamps ....................................5-47 Taillamps, Turn Signal, Stoplamps and Back-up Lamps .........................................5-49 License Plate Lamp ......................................5-50 Replacement Bulbs .......................................5-50 Windshield Wiper Blade Replacement ..............5-51 Tires ..............................................................5-52 Tire Sidewall Labeling ...................................5-53 Tire Terminology and Deﬁnitions .....................5-56 Inﬂation -

You will receive genuine GM parts and GM-trained and supported service people. Genuine GM parts have one of these marks: Accessories and Modiﬁcations When non-dealer/non-retailer accessories are added to your vehicle they can affect your vehicle’s performance and safety, including such things as, airbags, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like antilock brakes, traction control and stability control. Some of these accessories could even cause malfunction or damage not covered by warranty. GM Accessories are designed to complement and function with other systems on your vehicle. Your GM dealer/retailer can accessorize your vehicle using genuine GM Accessories. When you go to your GM dealer/retailer and ask for GM Accessories, you will know that GM-trained and supported service technicians will perform the work using genuine GM Accessories. Also, see Adding Equipment to Your Airbag-Equipped Vehicle on page 1-70. 5-3 California Proposition 65 Warning Most motor vehicles, including this one, contain and/or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Engine exhaust, many parts and systems (including some inside the vehicle), many ﬂuids, and some component wear by-products contain and/or emit these chemicals. California Perchlorate Materials Requirements Certain types of automotive applications, such as airbag initiators, seat belt pretensioners, and lithium batteries contained in remote keyless entry transmitters, may contain perchlorate materials. Special handling may be necessary. For additional information, see www.dtsc.ca.gov/hazardouswaste/perchlorate. 5-4 Doing Your Own Service Work {CAUTION: You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. (cid:127) Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before you attempt any vehicle maintenance task. (cid:127) Be sure to use the proper nuts, bolts, and other fasteners. English and metric fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt. If you want to do some of your own service work, you should use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see Service Publications Ordering Information on page 7-16. Your vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle on page 1-69. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See Maintenance Record on page 6-16. Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airﬂow around it. This can cause wind noise and can affect fuel economy and windshield washer performance. Check with your dealer/retailer before adding equipment to the outside of your vehicle. Fuel Use of the recommended fuel is an important part of the proper maintenance of your vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline. The 8th digit of the Vehicle Identiﬁcation Number (VIN) shows the code letter or number that identiﬁes your vehicle’s engine. The VIN is at the top left of the instrument panel. See Vehicle Identiﬁcation Number (VIN) on page 5-98. Gasoline Octane If your vehicle has the 3.4L V6 engine (VIN Code F), use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you might notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service. If your vehicle has the 3.6L V6 engine (VIN Code 7), use regular unleaded gasoline with a posted octane rating of 87 or higher. For best performance or trailer towing, you could choose to use middle grade 89 octane unleaded gasoline. If the octane rating is less than 87, you might notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service. 5-5 Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, you should not have to add anything to the fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean, or if your vehicle experiences problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Also, your dealer/retailer has additives that will help correct and prevent most deposit-related problems. Gasoline Speciﬁcations At a minimum, gasoline should meet ASTM speciﬁcation D 4814 in the United States or CAN/CGSB-3.5 or 3.511 in Canada. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Additives on page 5-5 for additional information. California Fuel If your vehicle is certiﬁed to meet California Emissions Standards, it is designed to operate on fuels that meet California speciﬁcations. See the underhood emission control label. If this fuel is not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal speciﬁcations, but emission control system performance might be affected. The malfunction indicator lamp could turn on and your vehicle might fail a smog-check test. See Malfunction Indicator Lamp on page 3-36. If this occurs, return to your authorized dealer/retailer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs might not be covered by your warranty. 5-6 Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel might be hard to ﬁnd. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by your warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend that you use these gasolines, if they comply with the speciﬁcations described earlier. However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels. Notice: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under your warranty. Some gasolines that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. We recommend against the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system could be affected. The malfunction indicator lamp might turn on. If this occurs, return to your dealer/retailer for service. 5-7 Filling the Tank {CAUTION: Fuel vapor burns violently and a fuel ﬁre can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Do not use cellular phones. Keep sparks, ﬂames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling your vehicle. This is against the law in some places. Do not re-enter the vehicle while pumping fuel. Keep children away from the fuel pump; never let children pump fuel. 5-8 The tethered fuel cap is located behind a hinged fuel door on the passenger’s side of the vehicle. To remove the fuel cap, turn it slowly counterclockwise. The fuel cap has a spring in it; if the cap is released too soon, it will spring back to the right. {CAUTION: {CAUTION: Fuel can spray out on you if you open the fuel cap too quickly. If you spill fuel and then something ignites it, you could be badly burned. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop. Then unscrew the cap all the way. Be careful not to spill fuel. Do not top off or overﬁll the tank and wait a few seconds after you have ﬁnished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-93. When replacing the fuel cap, turn it clockwise until it clicks. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See Malfunction Indicator Lamp on page 3-36. If a ﬁre starts while you are refueling, do not remove the nozzle. Shut off the ﬂow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately. If you need a new fuel cap, be sure to get Notice: the right type. Your dealer/retailer can get one for you. If you get the wrong type, it may not ﬁt properly. This may cause your malfunction indicator lamp to light and may damage your fuel tank and emissions system. See Malfunction Indicator Lamp on page 3-36. 5-9 Filling a Portable Fuel Container {CAUTION: Never ﬁll a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the fuel vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: (cid:127) Dispense fuel only into approved containers. (cid:127) Do not ﬁll a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed, or on any surface other than the ground. (cid:127) Bring the ﬁll nozzle in contact with the inside of the ﬁll opening before operating the nozzle. Contact should be maintained until the ﬁlling is complete. (cid:127) Do not smoke while pumping fuel. (cid:127) Do not use a cellular phone while pumping fuel. Checking Things Under the Hood {CAUTION: An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing, and tools away from any underhood electric fan. {CAUTION: Things that burn can get on hot engine parts and start a ﬁre. These include liquids like fuel, oil, coolant, brake ﬂuid, windshield washer and other ﬂuids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine. 5-10 Hood Release To open the hood, do the following: 1. Pull the handle with this symbol on it. It is located inside the vehicle, to the left of the brake pedal. 2. Then go to the front of the vehicle and move the secondary hood release lever to the right. 3. Lift the hood. Before closing the hood, be sure all the ﬁller caps are on properly. Then pull the hood down and close it ﬁrmly. 5-11 Engine Compartment Overview When you open the hood on the 3.4L V6, here is what you will see: 5-12 A. Engine Air Cleaner/Filter.

Engine Oil Checking Engine Oil It is a good idea to check the engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview on page 5-12 for the location of the engine oil dipstick. 1. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you do not do this, the oil dipstick might not show the actual level. 2. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. 5-15 When to Add Engine Oil See Engine Compartment Overview on page 5-12 for the location of the engine oil ﬁll cap. If the oil is below the cross-hatched area at the tip of the dipstick, add at least one quart/liter of the recommended oil. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Speciﬁcations on page 5-105. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. SAE 5W-30 may not appear on all caps. Be sure to add enough oil to put the level somewhere in the proper operating range in the cross-hatched area. Push the dipstick all the way back in when you are through. 5-16 What Kind of Engine Oil to Use (cid:127) SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. If you are in an area of extreme cold, where the temperature falls below −20°F (−29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for the engine at extremely low temperatures. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. (cid:127) American Petroleum Institute (API) starburst symbol Oils meeting these requirements should have the starburst symbol on the container. This symbol indicates that the oil has been certiﬁed by the American Petroleum Institute (API). 5-17 Look for three things: (cid:127) GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. Look for and use only an oil that meets GM Standard GM6094M. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A change engine oil light and a CHANGE ENGINE OIL SOON message will come on. Change the oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the oil life system might not indicate that an oil change is necessary for over a year. However, the engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your dealer/retailer has trained service people who will perform this work using genuine parts and reset the system. It is also important to check the oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change the oil at 3,000 miles (5 000 km) since the last oil change. Remember to reset the oil life system whenever the oil is changed. Look for this information on the oil container, and use only those oils that are identiﬁed as meeting GM Standard GM6094M and have the starburst symbol on the front of the oil container. Notice: Use only engine oil identiﬁed as meeting GM Standard GM6094M and showing the American Petroleum Institute Certiﬁed For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty. Engine Oil Additives Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you need for good performance and engine protection. Engine Oil Life System When to Change Engine Oil Your vehicle has a computer system that lets you know when to change the engine oil and ﬁlter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed. 5-18 How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change the engine oil and ﬁlter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change the oil prior to a change engine oil light or CHANGE ENGINE OIL SOON message being turned on, reset the system. 1. Turn the ignition key to ON/RUN with the engine off. 2. Fully press and release the accelerator pedal three times within ﬁve seconds. The change engine oil light will ﬂash while the system is resetting. 3. When the light stops ﬂashing, turn the key to LOCK/OFF. If the light or message comes back on and stays on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the ﬁlter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of used oil, ask your dealer/retailer, a service station, or a local recycling center for help. 5-19 To inspect or replace the engine air cleaner/ﬁlter, do the following: 1. Turn off the engine. 2. Disconnect the air ﬂow sensor electrical connector. 3. Loosen the screws on the clamps holding the air outlet duct in place. Do not pry the clamps off. Engine Air Cleaner/Filter The engine air cleaner/ﬁlter is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/ﬁlter at the Maintenance II intervals and replace it at the ﬁrst oil change after each 50,000 mile (80 000 km) interval. See Scheduled Maintenance on page 6-4 for more information. If you are driving in dusty/dirty conditions, inspect the ﬁlter at each engine oil change. How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/ﬁlter remove the ﬁlter from the vehicle and lightly shake the ﬁlter to release loose dust and dirt. If the ﬁlter remains caked with dirt, a new ﬁlter is required. 5-20 7. Reinstall the ﬁlter cover and latch the clamps. 8. Reattach the air outlet duct and tighten the screws on the clamps that hold the duct in place. 9. Reconnect the air ﬂow sensor electrical connector. {CAUTION: Operating the engine with the air cleaner/ﬁlter off can cause you or others to be burned. The air cleaner not only cleans the air; it helps to stop ﬂames if the engine backﬁres. If it is not there and the engine backﬁres, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/ﬁlter off. If the air cleaner/ﬁlter is off, a backﬁre can Notice: cause a damaging engine ﬁre. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/ﬁlter in place when you are driving. 5-21 4. Remove the air outlet duct. 5. Undo the clamps on the ﬁlter cover. To remove the cover, pull up on the front and then pull the cover out. 6. Inspect or replace the engine air cleaner/ﬁlter. Wipe all dust from inside of the housing and inspect the air cleaner and air outlet duct for cracks, cuts, and deterioration. The air outlet duct must be replaced if damaged. Automatic Transmission Fluid It is not necessary to check the transmission ﬂuid level. A transmission ﬂuid leak is the only reason for ﬂuid loss. If a leak occurs, take your vehicle to the dealer/retailer and have it repaired as soon as possible. Change the ﬂuid and ﬁlter at the intervals listed in Additional Required Services on page 6-6, and be sure to use the transmission ﬂuid listed in Recommended Fluids and Lubricants on page 6-12. Notice: Use of the incorrect automatic transmission ﬂuid may damage your vehicle, and the damages may not be covered by your warranty. Always use the automatic transmission ﬂuid listed in Recommended Fluids and Lubricants on page 6-12. For the 3.6L engine, the transmission ﬂuid will not reach the end of the dipstick unless the transmission is at operating temperature. If you need to check the transmission ﬂuid level, please take your vehicle to your dealer/retailer. 5-22 Engine Coolant The cooling system in your vehicle is ﬁlled with DEX-COOL® engine coolant. This coolant is designed to remain in your vehicle for ﬁve years or 150,000 miles (240 000 km), whichever occurs ﬁrst, if you add only DEX-COOL® extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see Engine Overheating on page 5-25. A 50/50 mixture of clean, drinkable water and DEX-COOL® coolant will: (cid:127) Give freezing protection down to −34°F (−37°C). (cid:127) Give boiling protection up to 265°F (129°C). (cid:127) Protect against rust and corrosion. (cid:127) Help keep the proper engine temperature. Let the warning lights and gages work as they should. Notice: Using coolant other than DEX-COOL® may cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant may require changing sooner, at the ﬁrst maintenance service after each 30,000 miles (50 000 km) or 24 months, whichever occurs ﬁrst. Any repairs would not be covered by your warranty. Always use DEX-COOL® (silicate-free) coolant in your vehicle. (cid:127) What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL® coolant which will not damage aluminum parts. If you use this coolant mixture, you do not need to add anything else. {CAUTION: Adding only plain water to the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, the engine could get too hot but you would not get the overheat warning. The engine could catch ﬁre and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant. If you use an improper coolant mixture, Notice: your engine could overheat and be badly damaged. The repair cost would not be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core, and other parts. If you have to add coolant more than four times a year, have your dealer/retailer check your cooling system. Notice: in your vehicle’s cooling system, you could damage your vehicle. Use only the proper mixture of the engine coolant listed in this manual for the cooling system. See Recommended Fluids and Lubricants on page 6-12 for more information. If you use extra inhibitors and/or additives 5-23 {CAUTION: Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap — even a little — when the engine and radiator are hot. The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the COLD FILL line. When your engine is warm, the level should be at the COLD FILL line or a little higher. Checking Coolant The surge tank is located on the driver’s side of the engine compartment. See Engine Compartment Overview on page 5-12 for more information on location. 5-24 Adding Coolant If you need more coolant, add the proper DEX-COOL® coolant mixture at the surge tank, but only when the engine is cool. {CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. When replacing the pressure cap, make sure it is hand-tight and fully seated. Engine Overheating You will ﬁnd a coolant temperature gage on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 3-35. There are several different types of engine overheating messages that may be displayed in the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-52. If Steam Is Coming From Your Engine {CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when the vehicles engine is overheated, the liquids in it can catch ﬁre. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See Overheated Engine Protection Operating Mode on page 5-26 for information on driving to a safe place in an emergency. If your engine catches ﬁre because you keep Notice: driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See Overheated Engine Protection Operating Mode on page 5-26 for information on driving to a safe place in an emergency. 5-25 If No Steam Is Coming From Your Engine An overheat warning can indicate a serious problem. If you get an engine overheat warning, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: (cid:127) Climb a long hill on a hot day. (cid:127) Stop after high-speed driving. Idle for long periods in traffic. Tow a trailer. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. If the air conditioner is on, turn it off. 2. Turn on your heater to full hot at the highest fan speed and open the windows as necessary. 3. Try to minimize engine load. If you are in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving. If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about ten minutes. If the warning does not come back on, you can drive normally. If the warning continues and you have not stopped, pull over, stop, and park your vehicle right away. 5-26 If there is still no sign of steam, you can idle the engine for three minutes while you are parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. Also, see “Overheated Engine Protection Operating Mode” later in this section. You may decide not to lift the hood but to get service help right away.
