been drinking — driver or passenger — is in a crash, that person’s chance of being killed or permanently disabled is higher than if the person had not been drinking.


{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.

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. 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. Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modifications on page 5-3.


Braking See Brake System Warning Light on page 3-27. 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 three-fourths 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 three-fourths 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, whether it is wet, dry, or 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 and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life.


4-6


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. Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modifications on page 5-3.


Anti-Lock Brake System (ABS) Your vehicle may have the Anti-Lock Brake System (ABS), an advanced electronic braking system that will help prevent a braking skid.


If your vehicle has ABS, this warning light on the instrument panel will come on briefly when you start your vehicle.


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 wheel. ABS 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.


4-7


Using ABS 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 ABS, you can steer and brake at the same time. However, if you do not have ABS, 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 cannot 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 ABS, 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.


As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS 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 ABS.


4-8


This will help you retain steering control. If you do have ABS, it is different. See Anti-Lock Brake System (ABS) on page 4-7. In many emergencies, steering can help you more than even the very best braking.


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 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. 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.


4-9


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-GM accessories can affect your vehicle’s performance. See Accessories and Modifications on page 5-3. 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 your brakes — but, unless you have anti-lock brakes, 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.


4-10


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.


Off-Road Recovery You may find that your right wheels have dropped off the edge of a road onto the shoulder while you are driving.


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.


• 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.


4-11


• 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.


• 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.


• 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 passenger side 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.


• 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.


4-12


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. 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 Brake System (ABS), remember: It helps avoid only the braking skid. If you do not have ABS, 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.


4-13


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. Here are some tips on night driving. • Drive defensively. • Do not drink and drive. • Adjust the inside rearview mirror to reduce the glare


from headlamps behind you.


• Since you cannot see as well, you may need to slow down and keep more space between you and other vehicles.


• Slow down, especially on higher speed roads. Your vehicle’s 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.


4-14


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. You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to re-adjust 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 the 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 the 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 the 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 cannot stop, accelerate, or turn as well because your tire-to-road traction is not as good as on dry roads. And, if your tires do 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.


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 fluid reservoir 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.


{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.


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 cannot, try to slow down before you hit them.


4-15


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 cannot 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 • 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.


• Have good tires with proper tread depth. See Tires


on page 5-45.

City Driving


Here are ways to increase your safety in city driving: • 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 4-18.


• 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.


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.


4-17


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.


4-18


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. 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: • Windshield Washer Fluid: Is the reservoir full? Are


all windows clean inside and outside?


• 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?


• Weather Forecasts: What is the weather outlook


along your route? Should you delay your trip a short time to avoid a major storm system?


• Maps: Do you have up-to-date maps?


4-19


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: • Make sure your vehicle is well ventilated, with a


comfortably cool interior.


• 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.


4-20


Hill and Mountain Roads


Driving on steep hills or mountains is different from driving in flat or rolling terrain. 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. • 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.


{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.


{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.


• 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.


• Know how to go uphill. Drive in the highest gear


possible.


• 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.


• 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.


• 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.


4-21


Winter Driving


Here are some tips for winter driving: • Have your vehicle in good shape for winter. • You may want to put winter emergency supplies in


your trunk.


Also see Tires on page 5-45.


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.


4-22


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 will have a lot less traction, or grip, and will need to be very careful.


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. Accelerate gently. Try not to break the fragile traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. Unless you have the Anti-Lock Brake System (ABS), you will want to brake very gently, too. If you do have ABS, see Anti-Lock Brake System (ABS) on page 4-7. This system improves your vehicle’s stability when you make a hard stop on a slippery road. Whether you have ABS or not, you will want to begin stopping sooner than you would on dry pavement. Without ABS, 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.


4-23


Remember, unless you have ABS, 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. • Whatever your braking system, allow greater


following distance on any slippery road.


• 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 cannot reach, such as 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.


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 your hazard flashers. • Tie a red cloth to your vehicle to alert police that


you have been stopped by the snow.


4-24


• 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.


You can run the engine to keep warm, but be careful.


{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 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.


4-25


If Your Vehicle is 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 on page 4-26. For information about using tire chains on your vehicle, see Tire Chains on page 5-57.


Rocking Your Vehicle to Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. Then shift back and forth between REVERSE (R) and a forward gear, or with a manual transaxle, between FIRST (1) or SECOND (2) and REVERSE (R), 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 4-34.


4-26


Loading Your Vehicle It is very important to know how much weight your vehicle can carry. This weight is called the vehicle capacity weight or maximum load amount 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 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.

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 shows the number of occupant seating positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds.


4-27


The tire and loading information label also shows 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 5-45
and Inflation - Tire Pressure on page 5-51. There is also important loading information on the Certification label. 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 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. 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.


4-28


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.


Your vehicle is neither designed nor intended to tow a trailer.

Label Example - United States


Label Example - Canada


A vehicle specific Certification label is attached to the center pillar (B-pillar), below the driver’s door latch. This label 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. And, if you do have a heavy load, you should spread it out. Do not carry more than 123 lbs (56 kg) in the vehicle’s trunk.


{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 or a professional towing service if you need to have your disabled vehicle towed. See Roadside Assistance Program on page 7-5. 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: • What is the towing capacity of the towing vehicle? Be sure you read the tow vehicle manufacturer’s recommendations.


• How far will you tow? Some vehicles have


restrictions on how far and how long they can tow.


• 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 will want to make sure your vehicle is prepared to be towed. See Before Leaving on a Long Trip on page 4-19.


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.


4-34


Dolly Towing Notice: Towing your vehicle from the rear with the front wheels on the ground could cause transaxle damage. Do not tow the vehicle from the rear with the front wheels on the road.


3. Put the vehicle in NEUTRAL (N). 4. Set the parking brake and then remove the key. 5. Clamp the steering wheel in a straight-ahead


position.


6. Release the parking brake.


Towing a Trailer Do not use your vehicle to tow a trailer. The vehicle is not designed or intended for such a use. Towing a trailer can adversely affect handling, durability and fuel economy.


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. Turn the ignition to ACC.

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:


Accessories and Modifications When you add non-GM accessories to your vehicle they can affect your vehicle’s performance and safety, including such things as, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like antilock brakes, traction control and stability control. Some of these accessories may 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 can accessorize your vehicle using genuine GM Accessories. When you go to your GM dealer and ask for GM Accessories, you will know that GM-trained and supported service technicians will perform the work using genuine GM Accessories.


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.


5-3


Your vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle on page 1-67. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See Part E: Maintenance Record on page 6-27.


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.


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 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 7-14.


5-4


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 may be affected. The malfunction indicator lamp may turn on and your vehicle may fail a smog-check test. See Malfunction Indicator Lamp on page 3-34. 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.


Fuel Use of the recommended fuel is an important part of the proper maintenance of your vehicle.


Gasoline Octane Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you may 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, your engine needs service.


Gasoline Specifications At a minimum, gasoline should meet ASTM specification D 4814 in the United States or CAN/CGSB-3.5 in Canada. Some gasolines may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). General Motors recommends against the use of gasolines containing MMT. See Additives on page 5-6 for additional information.


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 recommends against 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. In most cases, 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. 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 GM dealer has additives that will help correct and prevent most deposit-related problems. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area. General Motors recommends 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 your fuel system and also damage the plastic and rubber parts. That damage would not be covered under your warranty.


5-6


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. 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.


To open the fuel filler door, pull up on the release lever with this symbol on it. It is located on the floor on the outboard side of the driver’s seat.


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. 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 5-69. 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 3-34.


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.


5-8


{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 3-34.


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 hood release


handle inside the vehicle. It is located on the lower left side of the instrument panel.


2. Then go to the front of the vehicle and lift up on the


secondary hood release lever, located under the front center of the hood.


3. Lift the hood and release the hood prop from its


retainer located on the underside of the hood.


Before closing the hood, be sure all the filler caps are on properly. Then lift the hood to relieve pressure on the hood prop. Remove the hood prop from the slot in the inner fender and return the prop to its retainer. Lower the hood 12 inches (30 cm) above the vehicle and release it to latch fully. Check to make sure the hood is closed and repeat the process if necessary.


4. Place the hood prop into the slot on the inner


fender.

Engine Oil


If the oil pressure light appears on the instrument cluster, it means you need to check your engine oil level right away.


For more information, see Oil Pressure Light on page 3-37. You should check your engine oil level regularly; this is an added reminder. Checking Engine Oil It is a good idea to check your 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 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.


5-13


When to Add Engine Oil


What Kind of Engine Oil to Use


If the oil is below the lower hole at the tip of the dipstick (B), you will need to add at least one quart/liter of oil. 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 5-80. Notice: Do not add too much oil. If your engine has so much oil that the oil level gets above the upper hole (A) 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, between the holes on the dipstick. Push the dipstick all the way back in when you are through.


5-14


Look for two things: • 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.


• SAE 5W-30


As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. 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.


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.


5-15


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.


When to Change Engine Oil If any one of these is true for you, use the short trip/city maintenance schedule: • Most trips are less than 5 miles (8 km). This is


particularly important when outside temperatures are below freezing.


• Most trips include extensive idling, such as frequent


driving in stop-and-go traffic.


• You frequently use a carrier on top of your vehicle. • The vehicle is used for delivery service, police,


taxi, or other commercial application.


Driving under these conditions causes engine oil to break down sooner. If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months — whichever occurs first. If none of them is true, use the long trip/highway maintenance schedule. Change oil and filter every 7,500 miles (12 500 km) or 12 months — whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower.


5-16


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 engine air cleaner/filter every 15,000 miles (25 000 km) and replace it every 30,000 miles (50 000 km). 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 engine 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. To inspect or replace the filter, do the following: 1. Remove the screws and lift off the cover. 2. Inspect or replace the engine air cleaner/filter. 3. Put the cover back on tightly and tighten the screws.


5-17


See Part A: Scheduled Maintenance Services on page 6-4 for replacement intervals.


{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.


Automatic Transaxle Fluid When to Check Automatic Transaxle Fluid Check your automatic transaxle fluid level at least twice a year. Add fluid if needed. See At Least Twice a Year on page 6-19. How to Check Automatic Transaxle Fluid Because this operation can be a little difficult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick. Notice: Too much or too little fluid can damage the transaxle. Too much can mean that some of the fluid could come out and fall on hot engine or exhaust system parts, starting a fire. Too little fluid could cause the transaxle to overheat. Be sure to get an accurate reading if you check the transaxle fluid.


5-18


Wait at least 30 minutes before checking the transaxle fluid level if you have been driving: • When outside temperatures are above 90°F (32°C). • At high speed for quite a while. • In heavy traffic — especially in hot weather. To get the right reading, the fluid should be at normal operating temperature, which is 158°F to 176°F (70°C to 80°C). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it is colder than 50°F (10°C), you may have to drive longer. Checking the Fluid Level Prepare your vehicle as follows: 1. Park your vehicle on a level place. Keep the engine


running.


2. With the parking brake applied, place the shift lever


in PARK (P).


3. With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P).


4. Let the engine run at idle for three to five minutes.


Then, without shutting off the engine, follow these steps: The automatic transaxle dipstick is located toward the front of the engine compartment, near the power steering fluid reservoir. See Engine Compartment Overview on page 5-12 for more information on location. 1. Pull out the dipstick and wipe it with a clean rag


or paper towel.


2. Push the dipstick back in all the way, wait three


seconds and then pull it back out again.


3. Check both sides of the dipstick, and read the lower


level. The fluid level must be between the two dimples in the hot range.


4. If the fluid level is in the acceptable range, push the


dipstick back in all the way.


5-19


How to Add Automatic Transaxle Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See Part D: Recommended Fluids and Lubricants on page 6-25. If the fluid level is low, add only enough of the proper fluid to bring the level into the area between the two dimples in the hot range on the dipstick. 1. Pull out the dipstick. 2. Using a long-neck funnel, add enough fluid at the


dipstick hole to bring it to the proper level. It does not take much fluid, generally less than one pint (0.5 L). Do not overfill.


Notice: Use of the incorrect automatic transaxle fluid may damage your vehicle, and the damages may not be covered by your warranty. Always use the automatic transaxle fluid listed in Part D: Recommended Fluids and Lubricants on page 6-25. 3. After adding fluid, recheck the fluid level as described under “How to Check Automatic Transaxle Fluid,” earlier in this section.


4. When the correct fluid level is obtained, push the


dipstick back in all the way.


Manual Transaxle Fluid It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to the dealership service department and have it repaired as soon as possible. See Part D: Recommended Fluids and Lubricants on page 6-25 for the proper fluid to use.


Hydraulic Clutch There is one reservoir for both the brake and the hydraulic clutch fluid. See Brakes on page 5-32 for more information. The hydraulic clutch linkage in your vehicle is self-adjusting. The master cylinder reservoir is filled with hydraulic fluid. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. When to Check and What to Use Refer to the Maintenance Schedule to determine how often you should check the fluid level in your master cylinder reservoir and for the proper fluid. See Part B: Owner Checks and Services on page 6-18 and Part D: Recommended Fluids and Lubricants on page 6-25.


5-20


How to Check and Add Fluid


To check the fluid level, look on the side of the reservoir. If the fluid reaches the MAX (A) mark on the reservoir, the fluid level is correct. The reservoir is located near the back of the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location.


Engine 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 5-24. A 50/50 mixture of clean, drinkable water and proper coolant will: • Give freezing protection down to −34°F (−37°C). • Give boiling protection up to 265°F (129°C). • Protect against rust and corrosion. • Help keep the proper engine temperature. • Let the warning lights and gages work as they


should.


5-21


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 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 Part D: Recommended Fluids and Lubricants on page 6-25 for more information.


If you use extra inhibitors and/or additives


What to Use Use a 50/50 mixture of clean, drinkable water and coolant that meets GM Specification 1825M, which will not damage aluminum parts. You can also use a recycled coolant conforming to GM Specification 1825M with a complete coolant flush and refill. If you use this coolant mixture, you do not need to add anything else.


{CAUTION:


Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and the proper coolant.


5-22


Checking Coolant


The engine coolant surge tank is located in the rear of the engine compartment on the driver’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location.


{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 between the Maximum (A) and Minimum (B) marks on the coolant surge tank. The level rises at engine operation temperature and drops again when the engine cools down.


5-23


Adding Coolant If the level falls below the Minimum (B) mark, add the proper coolant mixture at the surge tank, but only when the engine is cool. If the surge tank is empty, a special fill procedure is necessary. See Cooling System on page 5-26 for instructions on “How to Add Coolant to the Coolant Surge Tank.”


Engine Overheating You will find a coolant temperature gage on your vehicle’s instrument panel cluster. See Engine Coolant Temperature Gage on page 3-28. If Steam Is Coming From Your Engine


{CAUTION:


{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.


Coolant Surge Tank Pressure Cap Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured.


5-24


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. Just 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 your 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.


If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 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. 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. You may decide not to lift the hood, but to get service help right away.


If your engine catches fire because you


Notice: keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. If No Steam Is Coming From Your Engine 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: • Climb a long hill on a hot day. • Stop after high-speed driving. • Idle for long periods in traffic. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. In heavy traffic, let the engine idle in NEUTRAL (N) while stopped. If it is safe to do so, pull off the road, shift to PARK (P) or NEUTRAL (N) and let the engine idle.


2. Turn on your heater to full hot at the highest fan


speed and open the windows as necessary.


5-25


Cooling System When you decide it is safe to lift the hood, here is what you will see:


{CAUTION:


An electric engine cooling fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.


If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. Make sure that the air conditioning is turned off. The coolant level should be between the Minimum and Maximum marks on the coolant surge tank when the engine is cool. If it is not, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system.


A. Coolant Surge Tank with Pressure Cap B. Electric Engine Cooling Fan


5-26


{CAUTION:


Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.


If there seems to be no leak, with the engine on, check to see if the electric engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, your vehicle needs service. Notice: Engine damage from running your engine without coolant is not covered by your warranty.


How to Add Coolant to the Coolant Surge Tank Notice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged. If you have not found a problem yet, check to see if coolant is visible in the surge tank. If coolant is visible but the coolant level is not between the Minimum and Maximum marks, add a 50/50 mixture of clean, drinkable water and proper coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. See Engine Coolant on page 5-21 for more information.


5-27


If no coolant is visible in the surge tank, add coolant as follows:


{CAUTION:


{CAUTION:


Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.


Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and a proper coolant.


In cold weather, water can freeze and crack


Notice: the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture.
