Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road. {CAUTION: Drinking and then driving is very dangerous. Your reﬂexes, perceptions, attentiveness and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Please do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink. Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. Also see Traction Control System (TCS) (3800 V6 Engine) on page 4-9. 4-5 Braking Braking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That is perception time. Then you have to bring up your foot and do it. That is reaction time. Average reaction time is about 3/4 of a second. But that is only an average. It might be less with one driver and as long as two or three seconds or more with another. Age, physical condition, alertness, coordination and eyesight all play a part. So do alcohol, drugs and frustration. But even in 3/4 of a second, a vehicle moving at 60 mph (100 km/h) travels 66 feet (20 m). That could be a lot of distance in an emergency, so keeping enough space between your vehicle and others is important. And, of course, actual stopping distances vary greatly with the surface of the road (whether it is pavement or gravel); the condition of the road (wet, dry, icy); tire tread; the condition of your brakes; the weight of the vehicle and the amount of brake force applied. Avoid needless heavy braking. Some people drive in spurts — heavy acceleration followed by heavy braking — rather than keeping pace with traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic 4-6 and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life. If your engine ever stops while you are driving, brake normally but do not pump your brakes. If you do, the pedal may get harder to push down. If your engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up, it may take longer to stop and the brake pedal will be harder to push. Anti-lock Brake System (ABS) Your vehicle may have anti-lock brakes. ABS is an advanced electronic braking system that will help prevent a braking skid. If your vehicle has anti-lock brakes, this warning light on the instrument panel will come on brieﬂy when you start your vehicle. When you start your engine, or when you begin to drive away, your anti-lock brake system will check itself. You may hear a momentary motor or clicking noise while this test is going on, and you may even notice that your brake pedal moves or pulses a little. This is normal. The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is what happens with ABS: A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels. As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly. 4-7 Remember: Anti-lock does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Using Anti-Lock Do not pump the brakes. Just hold the brake pedal down ﬁrmly and let anti-lock work for you. You may feel a slight brake pedal pulsation or notice some noise, but this is normal. Braking in Emergencies At some time, nearly every driver gets into a situation that requires hard braking. If you have anti-lock, you can steer and brake at the same time. However, if you do not have anti-lock, your ﬁrst reaction — to hit the brake pedal hard and hold it down — may be the wrong thing to do. Your wheels can stop rolling. Once they do, the vehicle can not respond to your steering. Momentum will carry it in whatever direction it was headed when the wheels stopped rolling. That could be off the road, into the very thing you were trying to avoid, or into traffic. If you do not have anti-lock, use a “squeeze” braking technique. This will give you maximum braking while maintaining steering control. You can do this by pushing on the brake pedal with steadily increasing pressure. In an emergency, you will probably want to squeeze the brakes hard without locking the wheels. If you hear or feel the wheels sliding, ease off the brake pedal. This will help you retain steering control. If you do have anti-lock, it is different. See “Anti-Lock Brake System” in this section. In many emergencies, steering can help you more than even the very best braking. 4-8 Traction Control System (TCS) (3800 V6 Engine) Your vehicle may have 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 both of the front wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power and may also upshift the transaxle and apply the front brakes to limit wheel spin. conditions allow you to safely use it again, you may re-engage the cruise control. See “Cruise Control” in Turn Signal/Multifunction Lever on page 3-7. The traction control system operates in all transaxle shift lever positions. But the system can upshift the transaxle only as high as the shift lever position you’ve chosen, so you should use the lower gears only when necessary. See Automatic Transaxle Operation on page 2-23. When the system is on, this warning light will come on to let you know if there’s a problem. United States Canada This light will come on when your traction control system is limiting wheel spin. See Traction Active Message on page 3-42. You may feel or hear the system working, but this is normal. If your vehicle is in cruise control when the traction control system begins to limit wheel spin, the cruise control will automatically disengage. When road See. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. To limit wheel spin, especially in slippery road conditions, you should always leave the traction control system on. But you can turn the system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required. See “Rocking Your Vehicle To Get It Out” under If You Are Stuck: In Sand, Mud, Ice or Snow on page 4-30. 4-9 To turn the system on or off, press the TRAC OFF button on the left side of the instrument panel. When you turn the system off, a chime will sound and the TRAC OFF warning light will come on and stay on. If the traction control system is limiting wheel spin when you press the button to turn the system off, the warning light will come on and the system will turn off right away. You can turn the system back on at any time by pressing the button again. The TRAC OFF warning light should go off. 4-10 Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Steering Tips Driving on Curves 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 your 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. 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 can not; 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 your brakes — but, unless you have anti-lock, not enough to lock your wheels. See Braking on page 4-6. 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. Suppose you are steering through a sharp curve. Then you suddenly apply the brakes. Both control systems — steering and braking — have to do their work where the tires meet the road. Unless you have four-wheel anti-lock brakes, adding the hard braking can demand too much of those places. You can lose control. The same thing can happen if you are steering through a sharp curve and you suddenly accelerate. Those two control systems — steering and acceleration — can overwhelm those places where the tires meet the road and make you lose control. 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 your 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. 4-11 Off-Road Recovery You may ﬁnd that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving. 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. 4-12 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 your steering wheel to go straight down the roadway. Passing The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds. A miscalculation, an error in judgment, or a brief surrender to frustration or anger can suddenly put the passing driver face to face with the worst of all traffic accidents — the head-on collision. So here are some tips for passing: “Drive ahead.” Look down the road, to the sides and to crossroads for situations that might affect your passing patterns. If you have any doubt whatsoever about making a successful pass, wait for a better time. (cid:127) Watch for traffic signs, pavement markings and lines. If you can see a sign up ahead that might indicate a turn or an intersection, delay your pass. A broken center line usually indicates it is all right to pass (providing the road ahead is clear). Never cross a solid line on your side of the lane or a double solid line, even if the road seems empty of approaching traffic. (cid:127) Do not get too close to the vehicle you want to pass while you are awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you are following a larger vehicle. Also, you will not have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance. (cid:127) When it looks like a chance to pass is coming up, start to accelerate but stay in the right lane and do not get too close. Time your move so you will be increasing speed as the time comes to move into the other lane. If the way is clear to pass, you will have a “running start” that more than makes up for the distance you would lose by dropping back. And if something happens to cause you to cancel your pass, you need only slow down and drop back again and wait for another opportunity. If other vehicles are lined up to pass a slow vehicle, wait your turn. But take care that someone is not trying to pass you as you pull out to pass the slow vehicle. Remember to glance over your shoulder and check the blind spot. 4-13 (cid:127) (cid:127) 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. (cid:127) Check your mirrors, glance over your shoulder, and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane. (Remember that your right outside mirror is convex. The vehicle you just passed may seem to be farther away from you than it really is.) Try not to pass more than one vehicle at a time on two-lane roads. Reconsider before passing the next vehicle. (cid:127) Do not overtake a slowly moving vehicle too rapidly. Even though the brake lamps are not ﬂashing, it may be slowing down or starting to turn. If you are being passed, make it easy for the following driver to get ahead of you. Perhaps you can ease a little to the right. 4-14 (cid:127) (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, your 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 and an acceleration skid are best handled by easing your foot off the accelerator pedal. 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 engine braking 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. If you have the anti-lock braking system, remember: It helps avoid only the braking skid. If you do not have anti-lock, then in a braking skid (where the wheels are no longer rolling), release enough pressure on the brakes to get the wheels rolling again. This restores steering control. Push the brake pedal down steadily when you have to stop suddenly. As long as the wheels are rolling, you will have steering control. 4-15 Driving at Night Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired — by alcohol or drugs, with night vision problems, or by fatigue. 4-16 Here are some tips on night driving. (cid:127) Drive defensively. (cid:127) Do not drink and drive. (cid:127) Adjust your inside rearview mirror to reduce the glare from headlamps behind you. (cid:127) Since you can not see as well, you may need to slow down and keep more space between you and other vehicles. (cid:127) Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead. In remote areas, watch for animals. If you are tired, pull off the road in a safe place and rest. 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 may require at least twice as much light to see the same thing at night as a 20-year-old. What you do in the daytime can also affect your night vision. For example, if you spend the day in bright sunshine you are wise to wear sunglasses. Your eyes will have less trouble adjusting to night. But if you are driving, do not wear sunglasses at night. They may cut down on glare from headlamps, but they also make a lot of things invisible. (cid:127) (cid:127) You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who does not lower the high beams, or a vehicle with misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlamps. Keep your windshield and all the glass on your vehicle clean — inside and out. Glare at night is made much worse by dirt on the glass. Even the inside of the glass can build up a ﬁlm caused by dust. Dirty glass makes lights dazzle and ﬂash more than clean glass would, making the pupils of your eyes contract repeatedly. Remember that your headlamps light up far less of a roadway when you are in a turn or curve. Keep your eyes moving; that way, it is easier to pick out dimly lighted objects. Just as your headlamps should be checked regularly for proper aim, so should your eyes be examined regularly. Some drivers suffer from night blindness — the inability to see in dim light — and are not even aware of it. Driving in Rain and on Wet Roads Rain and wet roads can mean driving trouble. On a wet road, you can not stop, accelerate or turn as well because your tire-to-road traction is not as good as on dry roads. And, if your tires don not have much tread left, you will get even less traction. It is always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reﬂexes are tuned for driving on dry pavement. 4-17 The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road and even people walking. It is wise to keep your windshield wiping equipment in good shape and keep your windshield washer tank ﬁlled with washer ﬂuid. Replace your windshield wiper inserts when they show signs of streaking or missing areas on the windshield, or when strips of rubber start to separate from the inserts. Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles. But if you can not, try to slow down before you hit them. {CAUTION: Wet brakes can cause accidents. They will not work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car wash, apply your brake pedal lightly until your brakes work normally. 4-18 Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that they can 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. Hydroplaning does not happen often. But it can if your tires do not have much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reﬂections from trees, telephone poles or other vehicles, and raindrops “dimple” the water’s surface, there could be hydroplaning. Hydroplaning usually happens at higher speeds. There just is not a hard and fast rule about hydroplaning. The best advice is to slow down when it is raining. Driving Through Deep Standing Water Notice: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody of your vehicle. If you can not avoid deep puddles or standing water, drive through them very slowly. Driving Through Flowing Water {CAUTION: Flowing or rushing water creates strong forces. If you try to drive through ﬂowing water, as you might at a low water crossing, your vehicle can be carried away. As little as six inches of ﬂowing water can carry away a smaller vehicle. If this happens, you and other vehicle occupants could drown. Do not ignore police warning signs, and otherwise be very cautious about trying to drive through ﬂowing water. Some Other Rainy Weather Tips (cid:127) Besides slowing down, allow some extra following distance. And be especially careful when you pass another vehicle. Allow yourself more clear room ahead, and be prepared to have your view restricted by road spray. (cid:127) Have good tires with proper tread depth. See Tires on page 5-58. 4-19 One of the biggest problems with city streets is the amount of traffic on them. You will want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: (cid:127) Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. Try to use the freeways that rim and crisscross most large cities. You will save time and energy. See Freeway Driving on page 4-21. Treat a green light as a warning signal. A traffic light is there because the corner is busy enough to need it. When a light turns green, and just before you start to move, check both ways for vehicles that have not cleared the intersection or may be running the red light. City Driving 4-20 (cid:127) (cid:127) Freeway Driving Mile for mile, freeways (also called thruways, parkways, expressways, turnpikes or superhighways) are the safest of all roads. But they have their own special rules. The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving. Too-fast or too-slow driving breaks a smooth traffic ﬂow. Treat the left lane on a freeway as a passing lane. At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic. Try to determine where you expect to blend with the ﬂow. Try to merge into the gap at close to the prevailing speed. Switch on your turn signal, check your mirrors and glance over your shoulder as often as necessary. Try to blend smoothly with the traffic ﬂow. Once you are on the freeway, adjust your speed to the posted limit or to the prevailing rate if it is slower. Stay in the right lane unless you want to pass. Before changing lanes, check your mirrors. Then use your turn signal. Just before you leave the lane, glance quickly over your shoulder to make sure there is not another vehicle in your “blind” spot. Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night. When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up. Drive on to the next exit. 4-21 The exit ramp can be curved, sometimes quite sharply. The exit speed is usually posted. Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are. Before Leaving on a Long Trip Make sure you are ready. Try to be well rested. If you must start when you are not fresh — such as after a day’s work — do not plan to make too many miles that ﬁrst part of the journey. Wear comfortable clothing and shoes you can easily drive in. Is your vehicle ready for a long trip? If you keep it serviced and maintained, it is ready to go. If it needs service, have it done before starting out. Of course, you will ﬁnd experienced and able service experts in GM dealerships all across North America. They will be ready and willing to help if you need it. Here are some things you can check before a trip: (cid:127) Windshield Washer Fluid: Is the reservoir full? Are all windows clean inside and outside? (cid:127) Wiper Blades: Are they in good shape? Fuel, Engine Oil, Other Fluids: Have you checked all levels? Lamps: Are they all working? Are the lenses clean? Tires: They are vitally important to a safe, trouble-free trip. Is the tread good enough for long-distance driving? Are the tires all inﬂated to the recommended pressure? (cid:127) Weather Forecasts: What is the weather outlook along your route? Should you delay your trip a short time to avoid a major storm system? (cid:127) Maps: Do you have up-to-date maps? 4-22 (cid:127) (cid:127) (cid:127) Highway Hypnosis Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy. Do not let it happen to you! If it does, your vehicle can leave the road in less than a second, and you could crash and be injured. What can you do about highway hypnosis? First, be aware that it can happen. Then here are some tips: (cid:127) Make sure your vehicle is well ventilated, with a comfortably cool interior. (cid:127) Keep your eyes moving. Scan the road ahead and to the sides. Check your rearview mirrors and your instruments frequently. If you get sleepy, pull off the road into a rest, service or parking area and take a nap, get some exercise, or both. For safety, treat drowsiness on the highway as an emergency. Hill and Mountain Roads Driving on steep hills or mountains is different from driving in ﬂat or rolling terrain. 4-23 (cid:127) {CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. 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 your engine running and your vehicle in gear when you go downhill. If you drive regularly in steep country, or if you are planning to visit there, here are some tips that can make your trips safer and more enjoyable. (cid:127) Keep your vehicle in good shape. Check all ﬂuid levels and also the brakes, tires, cooling system and transaxle. These parts can work hard on mountain roads. (cid:127) Know how to go down hills. The most important thing to know is this: let your engine do some of the slowing down. Shift to a lower gear when you go down a steep or long hill. {CAUTION: If you do not shift down, your 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 your engine assist your brakes on a steep downhill slope. 4-24 Winter Driving (cid:127) Know how to go uphill. You may want to shift down to a lower gear. The lower gears help cool your engine and transaxle, and you can climb the hill better. (cid:127) Stay in your own lane when driving on two-lane roads in hills or mountains. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane. (cid:127) As you go over the top of a hill, be alert. There could be something in your lane, like a stalled car or an accident. (cid:127) You may see highway signs on mountains that warn of special problems. Examples are long grades, passing or no-passing zones, a falling rocks area or winding roads. Be alert to these and take appropriate action. Here are some tips for winter driving: (cid:127) Have your vehicle in good shape for winter. (cid:127) You may want to put winter emergency supplies in your trunk. 4-25 Driving on Snow or Ice Most of the time, those places where your tires meet the road probably have good traction. However, if there is snow or ice between your tires and the road, you can have a very slippery situation. You will have a lot less traction or “grip” and will need to be very careful. 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. 4-26 Remember, unless you have anti-lock, if you brake so hard that your wheels stop rolling, you will just slide. Brake so your wheels always keep rolling and you can still steer. (cid:127) Whatever your braking system, 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 may appear in shaded areas where the sun can not reach: around clumps of trees, behind buildings or under bridges. Sometimes the surface of a curve or an overpass may 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. 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 may 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. Keep your traction control system on. It improves your ability to accelerate when driving on a slippery road. Even though your vehicle has a traction control system, you will want to slow down and adjust your driving to the road conditions. See Traction Control System (TCS) (3800 V6 Engine) on page 4-9. Unless you have the anti-lock braking system, you will want to brake very gently, too. (If you do have anti-lock, see Braking on page 4-6. This system improves your vehicle’s stability when you make a hard stop on a slippery road.) Whether you have the anti-lock braking system or not, you will want to begin stopping sooner than you would on dry pavement. Without anti-lock brakes, if you feel your vehicle begin to slide, let up on the brakes a little. Push the brake pedal down steadily to get the most traction you can. 4-27 If You Are Caught in a Blizzard (cid:127) Put on extra clothing or wrap a blanket around you. If you have no 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. 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 your hazard ﬂashers. Tie a red cloth to your vehicle to alert police that you have been stopped by the snow. 4-28 You can run the engine to keep warm, but be careful. (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 can not 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 your 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 your headlamps. Let the heater run for a while. 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. 4-29 If You Are Stuck: In Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you do not want to spin your wheels too fast. The method known as “rocking” can help you get out when you are stuck, but you must use caution. {CAUTION: If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transaxle or other parts of the vehicle can overheat. That could cause an engine compartment ﬁre or other damage. When you are stuck, spin the wheels as little as possible. Do not spin the wheels above 35 mph (55 km/h) as shown on the speedometer. Notice: Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transaxle back and forth, you can destroy your transaxle. See “Rocking Your Vehicle To Get It Out.” For information about using tire chains on your vehicle, see Tire Chains on page 5-74. Rocking Your Vehicle To Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. If your vehicle has traction control, you should turn the system off. See Traction Control System (TCS) (3800 V6 Engine) on page 4-9. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transaxle is in gear. By slowly spinning your wheels in the forward and reverse directions, you will cause a rocking motion that may free your vehicle. If that does not get you out after a few tries, you may need to be towed out. If you do need to be towed out, see Towing Your Vehicle on page 4-31. 4-30 Towing Towing Your Vehicle Consult your dealer or a professional towing service if you need to have your disabled vehicle towed. See Roadside Assistance Program on page 7-6. 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. 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 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 4-22. If you tow your vehicle with all four wheels Dinghy Towing Notice: on the ground, the drivetrain components could be damaged. The repairs would not be covered by your warranty. Do not tow your vehicle with all four wheels on the ground. Your vehicle was not designed to be towed with all four wheels on the ground. If your vehicle must be towed, you should use a dolly. See “Dolly Towing” that follows for more information. 4-31 (cid:127) Loading Your Vehicle It is very important to know how much weight your vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo and all nonfactory-installed options. Two labels on your vehicle show how much weight it may properly carry, the Tire and Loading Information label and the Certiﬁcation label. {CAUTION: Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear 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. Dolly Towing Your vehicle can be towed using a dolly. To tow your vehicle using a dolly, follow these steps: 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. 5. Releases the parking brake. 4-32 Tire and Loading Information Label A. Vehicle Capacity Weight Example 1 Example 2 A. Vehicle Capacity Weight The Tire and Loading Information label shows the seating capacity and the total weight your vehicle can properly carry. This weight is called the vehicle capacity weight. If your vehicle has the Tire and Loading Information label, Example 1, the label is attached to the center pillar, near the driver’s door latch. If your vehicle has the Tire-Loading Information label, Example 2, the label is on the inside trunk lid. 4-33 3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds. 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 of your vehicle. If your vehicle can tow a trailer, see Towing a Trailer on page 4-38, for important information on towing a trailer, towing safety rules and trailering tips. The Tire and Loading Information label also gives you the size and recommended inﬂation pressure for the factory-installed, original equipment tires on your vehicle. For more information on tires and inﬂation see Tires on page 5-58 and Inﬂation - Tire Pressure on page 5-65. There is also important loading information on the Certiﬁcation label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle; see “Certiﬁcation 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 pounds” on your vehicle placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 4-34 Example 1 Loading Your Vehicle Example 2 Loading Your Vehicle Item Description Total Item Description Total Vehicle Capacity Weight for Example 1= Subtract Occupant Weight 150 lbs (68 kg) × 2 = Available Occupant and Cargo Weight = 1,000 lbs (453 kg) 300 lbs (136 kg) 700 lbs (317 kg) Vehicle Capacity Weight for Example 2 = Subtract Occupant Weight 150 lbs (68 kg) × 5 = Available Occupant and Cargo Weight = 1,000 lbs (453 kg) 750 lbs (340 kg) 250 lbs (113 kg) 4-35 Refer to your vehicle’s tire and loading information label for speciﬁc information about your vehicle’s capacity weight and seating positions. The combined weight of the driver, passengers and cargo should never exceed your vehicle’s capacity weight. Also see Towing a Trailer on page 4-38. Example 3 Loading Your Vehicle Item Description Total Vehicle Capacity Weight for Example 3 = Subtract Occupant Weight 200 lbs (91 kg) × 5 = Available Occupant and Cargo Weight = 1,000 lbs (453 kg) 1,000 lbs (453 kg) 0 lbs (0 kg) 4-36 Certiﬁcation Label If you do have a heavy load, spread it out. Don’t carry more than 167 pounds (75 kg) in your trunk. The Certiﬁcation label is found on the rear edge of the driver’s door. It tells you the gross weight capacity of your vehicle, called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. Never exceed the GVWR for your vehicle or the Gross Axle Weight Rating (GAWR) for either the front or rear axle. {CAUTION: Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear 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. 4-37 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’ll keep going. Towing a Trailer {CAUTION: {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 trunk of your vehicle. In a trunk, put them as far forward as you can. 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. 4-38 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 for advice and information about towing a trailer with your vehicle. Your vehicle can tow a trailer if it is equipped with the proper trailer towing equipment. To identify what the vehicle trailering capacity is for your vehicle, you should read the information in “Weight of the Trailer” that appears later in this section. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. That’s the reason for this part. 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. Load-pulling components such as the engine, transaxle, wheel assemblies and tires are forced to work harder against the drag of the added weight. The engine is required to operate at relatively higher speeds and under greater loads, generating extra heat. What’s more, the trailer adds considerably to wind resistance, increasing the pulling requirements. 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’ll be driving. A good source for this information can be state or provincial police. (cid:127) Consider using a sway control. You can ask a hitch dealer about sway controls. (cid:127) Don’t tow a trailer at all during the ﬁrst 1,000 miles (1 600 km) your new vehicle is driven. Your engine, axle or other parts could be damaged. Then, during the ﬁrst 500 miles (800 km) that you tow a trailer, don’t drive over 50 mph (80 km/h) and don’t make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads. (cid:127) Obey speed limit restrictions when towing a trailer. Don’t drive faster than the maximum posted speed for trailers, or no more than 55 mph (90 km/h), to save wear on your vehicle’s parts. Three important considerations have to do with weight: the weight of the trailer, the weight of the trailer tongue and the total weight on your vehicle’s tires. 4-39 (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 1,000 lbs (454 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. And, it can also depend on any special equipment that you have on your vehicle. You can ask your dealer for our trailering information or advice, or you can write us at: Chevrolet Customer Assistance Center P.O. Box 33170 Detroit, MI 48232-5170 In Canada, write to: General Motors of Canada Limited Customer Communication Centre, 163-005 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7 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 4-40 the vehicle. And if you 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 4-32 for more information about your vehicle’s maximum load capacity. If you’re using a weight-carrying hitch or a weight-distributing hitch, the trailer tongue (A) should weigh 10 to 15 percent of the total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, 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’ll ﬁnd these numbers on the Tire-Loading Information label, See Loading Your Vehicle on page 4-32. Then be sure you don’t go over the GVW limit for your vehicle, including the weight of the trailer tongue. Hitches It’s important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow: The rear bumper on your vehicle is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it. Use only a frame-mounted hitch that does not attach to the bumper. (cid:127) Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sure to seal the holes later when you remove the hitch. If you don’t seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 2-31 in the Index. 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 so that the tongue will not drop to 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. And, never allow safety chains to drag on the ground. Trailer Brakes Does your trailer have its own brakes? Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. If your vehicle has anti-lock brakes, do not try to tap into your vehicle’s brake system. If you do, both brake systems won’t work well, or at all. (cid:127) Even if your vehicle doesn’t have anti-lock brakes, don’t tap into your vehicle’s brake system if the trailer’s brake system will use more than 0.02 cubic inch (0.3 cc) of ﬂuid from your vehicle’s master cylinder. If it does, both braking systems won’t work well. You could even lose your brakes. 4-41 (cid:127) (cid:127) (cid:127) Will the trailer brake parts take 3,000 psi (20 650 kPa) of pressure? If not, the trailer brake system must not be used with your vehicle. If everything checks out this far, then make the brake ﬂuid tap at the upper rear master cylinder port. But don’t use copper tubing for this. If you do, it will bend and break off. Use steel brake tubing. Driving with a Trailer Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll 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 the trailer hitch and platform (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. 4-42 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’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll 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’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. (cid:127) Turn Signals When Towing a Trailer When you tow a trailer, your vehicle may need additional wiring. Check with your dealer. 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’re 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 don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce your speed to around 45 mph (70 km/h) to reduce the possibility of engine and transaxle overheating. If you have overdrive, you may want to drive in THIRD (3) instead of AUTOMATIC OVERDRIVEX. 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, here’s how to do it: 1. Apply your regular brakes, but don’t 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. 4-43 When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: start your engine, shift into a gear, and 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’re pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle ﬂuid (don’t overﬁll), engine oil, drive 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’re trailering, it’s a good idea to review this information before you start your trip. Check periodically to see that all hitch nuts and bolts are tight. Engine Cooling When Trailer Towing Your cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 5-30. 4-44 (cid:127) (cid:127) (cid:127) Section 5 Service and Appearance Care Service ............................................................5-3 Doing Your Own Service Work .........................5-3 Adding Equipment to the Outside of Your Vehicle ..............................................5-4 Fuel ................................................................5-4 Gasoline Octane ............................................5-4 Gasoline Speciﬁcations ....................................5-5 California Fuel ...............................................5-5 Additives .......................................................5-6 Fuels in Foreign Countries ...............................5-6 Filling Your Tank ............................................5-7 Filling a Portable Fuel Container .......................5-9 Checking Things Under the Hood ....................................................5-10 Hood Release ..............................................5-11 Engine Compartment Overview .......................5-12 Engine Oil ...................................................5-17 Supercharger Oil ..........................................5-22 Engine Air Cleaner/Filter ................................5-23 Automatic Transaxle Fluid ..............................5-25 Engine Coolant .............................................5-27 Radiator Pressure Cap ..................................5-29 Engine Overheating .......................................5-30 Cooling System ............................................5-32 Power Steering Fluid .....................................5-42 Windshield Washer Fluid ................................5-43 Brakes ........................................................5-44 Battery ........................................................5-46 Jump Starting ...............................................5-47 Headlamp Aiming ...........................................5-52 Bulb Replacement ..........................................5-52 Halogen Bulbs ..............................................5-52 Headlamps, Front Turn Signal, and Parking Lamps ..........................................5-53 Taillamps, Turn Signal, Stoplamps and Sidemarker Lamps .....................................5-55 Back-Up Lamps ............................................5-56 Replacement Bulbs .......................................5-56 Windshield Wiper Blade Replacement ..............5-57 5-1 Section 5 Service and Appearance Care Tires ..............................................................5-58 Inﬂation - Tire Pressure .................................5-65 Tire Pressure Monitor System .........................5-66 Tire Inspection and Rotation ...........................5-68 When It Is Time for New Tires .......................5-69 Buying New Tires .........................................5-70 Uniform Tire Quality Grading ..........................5-71 Wheel Alignment and Tire Balance ..................5-72 Wheel Replacement ......................................5-72 Tire Chains ..................................................5-74 If a Tire Goes Flat ........................................5-75 Changing a Flat Tire .....................................5-76 Compact Spare Tire ......................................5-86 Appearance Care ............................................5-87 Cleaning the Inside of Your Vehicle .................5-87 Care of Safety Belts ......................................5-90 Weatherstrips ...............................................5-90 Cleaning the Outside of Your Vehicle ..............5-90 Sheet Metal Damage .....................................5-92 Finish Damage .............................................5-92 Underbody Maintenance ................................5-93 Chemical Paint Spotting .................................5-93 Vehicle Care/Appearance Materials ..................5-94 Vehicle Identiﬁcation ......................................5-95 Vehicle Identiﬁcation Number (VIN) .................5-95 Service Parts Identiﬁcation Label .....................5-95 Electrical System ............................................5-95 Add-On Electrical Equipment ..........................5-95 Headlamp Wiring ..........................................5-96 Windshield Wiper Fuses ................................5-96 Power Windows and Other Power Options .......5-96 Fuses and Circuit Breakers ............................5-96 Capacities and Speciﬁcations ........................5-102 5-2 Service Your dealer knows your vehicle best and wants you to be happy with it. We hope you will go to your dealer for all your service needs. You will get genuine GM parts and GM-trained and supported service people. We hope you will want to keep your GM vehicle all GM. Genuine GM parts have one of these marks: Doing Your Own Service Work If you want to do some of your own service work, you will want to 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 7-11. Your vehicle has an air bag system. Before attempting to do your own service work, see Servicing Your Air Bag-Equipped Vehicle on page 1-61. 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 6-15. {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. CAUTION: (Continued) 5-3 CAUTION: (Continued) (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. 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 may cause wind noise and affect windshield washer performance. Check with your dealer 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. Gasoline Octane If your vehicle has the 3400 V6 engine (VIN Code E) or the 3800 V6 engine (VIN Code K), use regular unleaded gasoline with a posted octane of 87 or higher. If the octane is less than 87, you may get a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine. A little pinging noise when you accelerate or drive uphill is considered normal. This does not indicate a problem exists or that a higher-octane fuel is necessary. If you are using 87 octane or higher-octane fuel and you hear heavy knocking, your engine needs service. If your vehicle has the 3800 Supercharged V6 engine (VIN Code 1), use only premium unleaded gasoline with a posted octane of 91 or higher. In an emergency, you may be able to use a lower octane — as low as 87 — if heavy knocking does not occur. Reﬁll your tank with premium fuel as soon as possible. Otherwise, you might damage your engine. If you are using 91 octane or higher-octane fuel and you hear heavy knocking, your engine needs service. 5-4 Gasoline Speciﬁcations It is recommended that gasoline meet speciﬁcations which were developed by automobile manufacturers around the world and contained in the World-Wide Fuel Charter which is available from the Alliance of Automobile Manufacturers at www.autoalliance.org. Gasoline meeting these speciﬁcations could provide improved driveability and emission control system performance compared to other gasoline. In Canada, look for the “Auto Makers’ Choice” label on the pump. California Fuel If your vehicle is certiﬁed to meet California Emission Standards (see the underhood emission control label), it is designed to operate on fuels that meet California speciﬁcations. 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 may be affected. The malfunction indicator lamp may turn on (see Malfunction Indicator Lamp on page 3-37 ) and your vehicle may fail a smog-check test. If this occurs, return to your authorized GM dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty. Canada Only 5-5 Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your authorized GM dealer for service. Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may 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. Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. General Motors recommends that you buy gasolines that are advertised to help keep fuel injectors and intake valves clean. If your vehicle experiences problems due to dirty injectors or valves, try a different brand of gasoline. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air. General Motors recommends that you use these gasolines, particularly if they comply with the speciﬁcations described earlier. Notice: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in your fuel system and also damage the plastic and rubber parts. That damage would not be covered under your warranty. 5-6 Filling Your 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. 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. Keep children away from the fuel pump; never let children pump fuel. Turn your vehicle off to refuel. The fuel cap is located behind a hinged door on the driver’s side of the vehicle. 5-7 {CAUTION: If you spill fuel and then something ignites it, you could be badly burned. Fuel can spray out on you if you open the fuel cap too quickly. 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. Don’t top off or overﬁll your tank, and wait a few seconds after you’ve ﬁnished pumping before you remove the nozzle. Clean fuel from painted surfaces as soon as possible. See Cleaning the Outside of Your Vehicle on page 5-90. When ﬁlling the tank do not overﬁll by squeezing in much more fuel after the pump shuts off. While refueling, let the fuel cap hang by the tether below the fuel ﬁll opening. To remove the fuel cap, turn it slowly to the left (counterclockwise). 5-8 When you put the fuel cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you fully install the cap. 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 3-37. {CAUTION: 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 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 3-37. 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 gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: (cid:127) Dispense gasoline 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 gasoline. 5-9 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 located inside the vehicle near the parking brake pedal. 2. Then go to the front of the vehicle and release the secondary hood latch, located near the center of the hood front, by pushing the latch 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 3400 V6 (Code E) engine, you’ll see the following: 5-12 A.

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. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level. 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. A. Windshield Washer Fluid Reservoir. See Windshield Washer Fluid on page 5-43. B. Battery. See Battery on page 5-46. C.

But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Speciﬁcations on page 5-102. Notice: Do not add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged. See Engine Compartment Overview on page 5-12 for the location of the engine oil ﬁll cap. 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. What Kind of Engine Oil to Use Look for two things: (cid:127) GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M. 5-18 (cid:127) SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. However, if it is going to be 0°F (–18°C) or above and SAE 5W-30 is not available, you may use SAE 10W-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certiﬁed by the American Petroleum Institute (API). You should 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. 5-19 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. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and ﬁlter must be changed at least once a year and at this time the system must be reset. Your dealer has GM-trained service people who will perform this work using genuine GM parts and reset the system. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. 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. GM Goodwrench® oil meets all the requirements 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 your engine at extremely low temperatures. Engine Oil Additives Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection. When to Change Engine Oil (GM Oil Life System) 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, 5-20 How to Reset the CHANGE ENGINE OIL Message The GM Oil Life System calculates when to change your engine oil and ﬁlter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL message being turned on, reset the system. After changing the engine oil, the system must be reset. To reset the CHANGE ENGINE OIL message use one of the following procedures: Using the Radio 1. Turn the ignition to ACC or ON, with the radio off. 2. Press and hold the TUNE DISP knob on the radio for at least ﬁve seconds until SETTINGS is displayed. 3. Press the SEEK PSCAN up or down arrow to scroll through the main menu. 4. Scroll until OIL LIFE appears on the display. 5. Press the 1 PREV or 2 NEXT buttons to enter the submenu. RESET will be displayed. 6. Press the TUNE DISP knob to reset. A chime will be heard to verify the new setting and DONE will be displayed for one second. 7. Once the indicator has been reset, scroll until EXIT appears on the display. 8. Press the TUNE DISP knob to exit programming. A chime will be heard to verify the exit. 9. Turn the key to OFF. If the CHANGE ENGINE OIL message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. Using the Accelerator Pedal 1. Turn the ignition to ON, with the engine off. 2. Fully press and release the accelerator pedal slowly three times within ﬁve seconds. If the CHANGE ENGINE OIL message ﬂashes, the system is reset. However, if it stays on, it did not reset. Repeat the procedure. 3. Turn the key to OFF. If the CHANGE ENGINE OIL message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. 5-21 What to Do with Used Oil Used engine oil contains certain elements that may 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 your used oil, ask your dealer, a service station or a local recycling center for help. Supercharger Oil Unless you are technically qualiﬁed and have the proper tools, you should let your dealer or a qualiﬁed service center perform this maintenance. When to Check Check oil level every 30,000 miles (50 000 km) or every 36 months, whichever occurs ﬁrst. What Kind of Oil to Use Use only the recommended supercharger oil. See Recommended Fluids and Lubricants on page 6-12. 5-22 How to Check and Add Oil Park the vehicle on a level surface. Check oil only when the engine is cold. Allow the engine to cool two to three hours after running. {CAUTION: If you remove the supercharger oil ﬁll plug while the engine is hot, pressure may cause hot oil to blow out of the oil ﬁll hole. You may be burned. Do not remove the plug until the engine cools. 1. Clean the area around the oil ﬁll plug before removing it. Engine Air Cleaner/Filter When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/ﬁlter at every oil change and replace at the ﬁrst oil change after 25,000 miles (40 000 km).
