Notice: system with a negative ground, both vehicles can be damaged. Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle. 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put an automatic transmission in PARK (P) or a manual transmission in NEUTRAL before setting the parking brake. If you have a four-wheel-drive vehicle, be sure the transfer case is not in NEUTRAL (N).


If you leave your radio or other accessories


Notice: on during the jump starting procedure, they could be damaged. The repairs would not be covered by your warranty. Always turn off your radio and other accessories when jump starting your vehicle. 3. Turn off the ignition on both vehicles. Unplug


unnecessary accessories plugged into the cigarette lighter or the accessory power outlets. Turn off the radio and all lamps that are not needed. This will avoid sparks and help save both batteries. And it could save the radio!


4. Open the hoods and locate the batteries. Find the positive (+) and negative (−) terminal locations on each vehicle. See Engine Compartment Overview on page 5-12 for more information on location.


{CAUTION:


{CAUTION:


Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the batteries have enough water. You do not need to add water to the ACDelco® battery (or batteries) installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you do not, explosive gas could be present. Battery fluid contains acid that can burn you. Do not get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.


Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.


5. Check that the jumper cables do not have loose or


missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (−) will go to a heavy, unpainted metal engine part or to a remote negative (−) terminal if the vehicle has one. Do not connect positive (+) to negative (−) or you will get a short that would damage the battery and maybe other parts too. And do not connect the negative (−) cable to the negative (−) terminal on the dead battery because this can cause sparks.


5-43


6. Connect the red


positive (+) cable to the positive (+) terminal of the dead battery. Use a remote positive (+) terminal if the vehicle has one.


7. Do not let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one.


8. Now connect the black negative (−) cable to the negative (−) terminal of the good battery. Use a remote negative (−) terminal if the vehicle has one. Do not let the other end touch anything until the next step. The other end of the negative (−) cable does not go to the dead battery. It goes to a heavy, unpainted metal engine part, or to a remote negative (−) terminal on the vehicle with the dead battery.


9. Connect the other end of the negative (−) cable at


least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, and the chance of sparks getting back to the battery is much less.


10. Now start the vehicle with the good battery and run


the engine for a while.


11. Try to start the vehicle that had the dead battery. If


it will not start after a few tries, it probably needs service.

If the jumper cables are removed in the


Notice: wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by your warranty. Remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal.


To disconnect the jumper cables from both vehicles, do the following: 1. Disconnect the black negative (−) cable from the


vehicle that had the dead battery.


2. Disconnect the black negative (−) cable from the


vehicle with the good battery.


3. Disconnect the red positive (+) cable from the


vehicle with the good battery.


4. Disconnect the red positive (+) cable from the other


vehicle.

5-56


{CAUTION:


Poorly maintained and improperly used tires are dangerous.


(cid:127) Overloading your tires can cause


overheating as a result of too much friction. You could have an air-out and a serious accident. See Loading Your Vehicle on page 4-46.


(cid:127) Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. See Inflation - Tire Pressure on page 5-62.


(cid:127) Overinflated tires are more likely to be cut,


punctured or broken by a sudden impact — such as when you hit a pothole. Keep tires at the recommended pressure.


(cid:127) Worn, old tires can cause accidents. If


your tread is badly worn, or if your tires have been damaged, replace them.


Tire Sidewall Labelling Useful information about a tire is molded into its sidewall. The examples below show a typical passenger vehicle tire and a compact spare tire sidewall.


Passenger (P-Metric) Tire Example


(A) Tire Size: The tire size is a combination of letters and numbers used to define a particular tire’s width, height, aspect ratio, construction type and service description. See the “Tire Size” illustration later in this section for more detail.


(B) TPC Spec (Tire Performance Criteria Specification): Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines. (C) DOT (Department of Transportation): The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S. Department of Transportation Motor Vehicle Safety Standards. (D) Tire Identification Number (TIN): The letters and numbers following DOT (Department of Transportation) code is the Tire Identification Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture.


(E) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread.


(F) Uniform Tire Quality Grading (UTQG): Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resistance. For more information see Uniform Tire Quality Grading on page 5-67.


(G) Maximum Cold Inflation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load.


5-57


(B) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread. (C) Tire Identification Number (TIN): The letters and numbers following the DOT (Department of Transportation) code is the Tire Identification Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture.


(D) Maximum Cold Inflation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load.


(E) Tire Inflation: The temporary use tire or compact spare tire should be inflated to 60 psi (420 kPa). For more information on tire pressure and inflation see Inflation - Tire Pressure on page 5-62. (F) Tire Size: A combination of letters and numbers define a tire’s width, height, aspect ratio, construction type and service description.

Inflation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not. If your tires do not have enough air (under-inflation), you can get the following:


Too much flexing Too much heat Tire overloading


(cid:127) Premature or irregular wear (cid:127) Poor handling (cid:127) Reduced fuel economy If your tires have too much air (over-inflation), you can get the following: (cid:127) Unusual wear (cid:127) Poor handling (cid:127) Rough ride (cid:127) Needless damage from road hazards


5-62


(cid:127) (cid:127) (cid:127) A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s door latch. This label shows your vehicle’s original equipment tires and the correct inflation pressures for your tires when they are cold. The recommended cold tire inflation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity. For additional information regarding how much weight your vehicle can carry, and an example of the tire and loading information label, see Loading Your Vehicle on page 4-46. How you load your vehicle affects vehicle handling and ride comfort, never load your vehicle with more weight than it was designed to carry. When to Check Check your tires once a month or more. Also check the tire pressure of the spare tire. If you have a compact spare tire, it should be at 60 psi (420 kPa). See Spare Tire on page 5-84 for additional information.


How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are underinflated. Check the tire’s inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.


5-63


Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-65 and Wheel Replacement on page 5-69 for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench to tighten the cable. See Changing a Flat Tire on page 5-72. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Part A: Scheduled Maintenance Services on page 6-4, for scheduled rotation intervals.


5-64


When rotating your tires, always use one of the correct rotation patterns shown here. If your vehicle has a compact spare tire or a spare tire that does not match your vehicle’s road tires and wheels, in size and type, do not include the spare in the tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. For the location of the tire and loading information label see Loading Your Vehicle on page 4-46. Make certain that all wheel nuts are properly tightened, see “Wheel Nut Torque” under Capacities and Specifications on page 5-102 for the proper wheel nut torque specification.


{CAUTION:


Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. See Changing a Flat Tire on page 5-72.


When It Is Time for New Tires


One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators.


You need a new tire if any of the following statements are true: (cid:127) You can see the indicators at three or more places


around the tire.


(cid:127) You can see cord or fabric showing through the


tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. The tire has a bump, bulge or split. The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage.


5-65


(cid:127) (cid:127) (cid:127) Buying New Tires To find out what kind and size of tires you need, look at the Tire and Loading Information label. For more information about this label and its location on your vehicle, See Loading Your Vehicle on page 4-46. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, GM recommends that you get tires with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by an “MS” (for mud and snow). If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires.


{CAUTION:


Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It’s all right to drive with your compact spare (if you have one). It was developed for use on your vehicle.


{CAUTION:


If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle.


5-66


Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.


Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1.5) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction – AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.


5-67


Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. If you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced.


Temperature – A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Wheel Replacement Replace any wheel that is bent, cracked or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle.


{CAUTION:


Using the wrong replacement wheels, wheel bolts or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts for replacement.


Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-72 for more information.

Used Replacement Wheels


Tire Chains


{CAUTION:


{CAUTION:


Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel.


Do not use tire chains. There is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, re-adjust or remove the device if it is contacting your vehicle, and do not spin your wheels. If you do find traction devices that will fit, install them on the rear tires.


5-70


If a Tire Goes Flat It’s unusual for a tire to “blowout” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible.


{CAUTION:


Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for changing a flat tire.


If a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely.


5-71


Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.


{CAUTION:


Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving:


1. Set the parking brake firmly. 2. Put an automatic transmission shift lever in PARK (P), or shift a manual transmission to FIRST (1) or REVERSE (R).


3. Turn off the engine and do not restart while


the vehicle is raised.


4. Do not allow passengers to remain in the


vehicle.

CAUTION:


(Continued)


Put the wheel blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side, at the opposite end of the vehicle.


When you have a flat tire, use the following example as a guide to assist you in the placement of wheel blocks.


The following information will tell you next how to use the jack and change a tire.


Removing the Spare Tire and Tools The jacking equipment you’ll need is stored along the driver’s side inner rear quarter panel. In some cases, you may have to remove the spare tire in order to reach the jack. The following instructions explain how to remove the spare tire, depending on where it is mounted on your vehicle. See Spare Tire on page 5-84.


1. Remove your jack cover by pulling up on the latch(es) on the cover (C). Remove the wheel blocks (D), jack (G) and wheel wrench (F).


If you remove or restow a tire from/to the


Notice: storage position under the vehicle when it is supported by a jack, you could damage the tire and/or your vehicle. Always remove or restow a tire when the vehicle is on the ground.


2. Remove the


underbody-mounted spare by inserting the chisel end of the wheel wrench, on an angle, into the hoist shaft hole in the rear bumper. Be sure the chisel end of the wheel wrench connects into the hoist shaft.


3. Turn the wheel wrench counterclockwise to lower the spare tire. Keep turning the wheel wrench until the spare tire has been completely lowered.


4. Tilt the retainer at the end of the cable and pull it


through the wheel opening.


5-73


If you drive away before the spare tire


5. Pull the tire out from under the vehicle. Notice: cable has been reinstalled, you could damage your vehicle. Always reinstall this cable before driving your vehicle. If you have an inside-mounted spare tire, the tire must be removed in order to have access to the jack storage. To remove an inside-mounted spare tire, reach into your tire’s cover and unscrew the wing nut at the center of the wheel. Remove it and the retainer. Unhook the tire from the mounting bracket and remove the cover. To remove a rear-mounted spare tire, first make sure that the carrier arm is fully-latched to the tailgate. Then remove the spare tire cover.


If you have this feature, the locking wheel nut can be removed by snapping the rubber weather cover off the face of the lock case.


Insert the key and pull the lock case straight off. It is not necessary to turn the key.


5-74


Put the spare tire near the flat tire.


The tools you’ll be using include the jack (A) and wheel wrench (B). Your vehicle may also have an optional hub cap removal tool.


Removing the Flat Tire and Installing the Spare Tire


Position the chisel end of your wheel wrench, or the hub cap removal tool (if equipped), in the notch of the hub cap and pry off the hub cap. Some of the molded plastic hub caps have imitation wheel nuts molded into them. The wheel wrench won’t fit these imitation nuts, so don’t try to remove them with the socket end of the wheel wrench.


5-75


If you have individual wheel nut caps that cover each nut, they must be removed in order to get to the wheel nuts. Use the socket end of the wheel wrench to remove the wheel nut caps. Your wheel nut caps may attach your hub cap to the wheel. Remove these wheel nut caps before you take off the hub cap.


1. Using the wheel wrench, loosen all the wheel nuts.


Don’t remove them yet.


2. Turn the jack handle clockwise to raise the jack


lift head.


3. Fit the jack into the appropriate hole nearest the


flat tire.


5-76


A. Front Frame Hole B. Rear Frame Hole (2-Door) or Spring Hanger


Hole (4-Door)


{CAUTION:


Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.


5-77


{CAUTION:


Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.


4. Raise the vehicle by turning the jack handle


clockwise. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit underneath the wheel well.


5. Remove all the wheel nuts and take off the flat tire.


{CAUTION:


Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off.


5-78


6. Remove any rust or dirt


from the wheel bolts, mounting surfaces and spare wheel.


8. Put the nuts on by


hand. Make sure the rounded end is toward the wheel.


7. Place the spare on the wheel mounting surface.


{CAUTION:


Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident.


Tighten each nut by hand until the wheel is held against the hub. If a nut can’t be turned by hand, use the wheel wrench and see your dealer as soon as possible.


5-79


{CAUTION:


Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications on page 5-102 for wheel nut torque specification.


Improperly tightened wheel nuts can lead


Notice: to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications on page 5-102 for the wheel nut torque specification.


9. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely.


5-80


10. Use the wrench to


tighten the wheel nuts firmly in a crisscross sequence as shown.


Notice: An aluminum wheel with a flat tire should always be stored under the vehicle with the hoist. However, storing it that way for an extended period could damage the wheel. To avoid this, have the tire repaired as soon as possible.


Storing a Flat or Spare Tire and Tools Store the flat tire in the same location as your spare tire.


{CAUTION:


Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

Push the lock case to be sure it is secured. The special lug nut and lock case is not intended to be used on any road wheel, only on the spare wheel carrier.


Spare Tire Compact Spare Tire Your vehicle may be equipped with a compact spare tire. Although the compact spare tire was fully inflated when the vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on the vehicle, stop as soon as possible and make sure the spare tire is correctly inflated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can finish your trip and have the full-size tire repaired or replaced at your convenience. Of course, it is best to replace the spare with a full-size tire as soon as possible. The spare tire will last longer and be in good shape in case it is needed again.

Notice: When the compact spare is installed, do not take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Do not use the compact spare on other vehicles. And do not mix the compact spare tire or wheel with other wheels or tires. They will not fit. Keep the spare tire and its wheel together. Notice: Tire chains will not fit your compact spare. Using them can damage your vehicle and can damage the chains too. Do not use tire chains on your compact spare.


Spare Tire Your vehicle may be equipped with a spare tire, which, when new, was fully inflated. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure on page 5-62 and Loading Your Vehicle on page 4-46 for information regarding proper tire inflation and loading your vehicle. For instructions on how to remove, install or store a spare tire, see Changing a Flat Tire on page 5-72. After installing the spare tire on your vehicle, you should stop as soon as possible and make sure the spare is correctly inflated. Have the damaged or flat road tire repaired or replaced as soon as you can and installed back onto your vehicle. This way, a spare tire will be available in case you need it again. Your vehicle may have a different size spare tire than the road tires — those originally installed on your vehicle. This spare tire was developed for use on your vehicle, so it’s all right to drive on it. If your vehicle has a spare tire that does not match your vehicle’s original road tires and wheels in size and type, do not include the spare in the tire rotation.


5-85


Appearance Care Cleaning products can be hazardous. Some are toxic. Other cleaning products can burst into flames if a match is struck near them or if they get on a hot part of the vehicle. Some are dangerous if their fumes are inhaled in an enclosed space. When anything from a container is used to clean the vehicle, be sure to follow the manufacturer’s warnings and instructions. Always open the doors or windows of the vehicle when cleaning the inside. Never use these to clean the vehicle: (cid:127) Gasoline (cid:127) Benzene (cid:127) Naphtha (cid:127) Carbon Tetrachloride (cid:127) Acetone (cid:127) Paint Thinner

Do not use any of these products unless this manual says you can. In many uses, these will damage the vehicle: (cid:127) Alcohol


Laundry Soap


(cid:127) Bleach (cid:127) Reducing Agents


Fabric/Carpet Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic, and painted surfaces with a clean, damp cloth. GM-approved cleaning products can be obtained from your dealer. Here are some cleaning tips: (cid:127) Always read the instructions on the cleaner label. (cid:127) Clean up stains as soon as you can before they set. (cid:127) Carefully scrape off any excess stain. (cid:127) Use a clean cloth or sponge, and change to a clean


area often. A soft brush may be used if stains are stubborn. To avoid forming a ring on fabric after spot cleaning, clean the entire area immediately or it will set.


(cid:127) (cid:127) (cid:127) (cid:127) Most stains can be removed with club soda water. To clean, use the following instructions: 1. For liquids: blot with a clean, soft, white cloth. For


solids: remove as much as possible and then vacuum or brush.


2. Apply club soda water to a clean, soft, white cloth.


Do not over-saturate; the cloth should not drip water.


3. Clean the entire area. Avoid getting the fabric


too wet.


4. Start cleaning from the seams into the stain to


avoid a ring effect.


5. Continue cleaning, using a clean area of the cloth


each time it becomes soiled.


6. When the stain is removed, blot the cleaned area


with another dry, clean, soft, white cloth.


Using Cleaner on Fabric 1. First, try the cleaner on an area of the fabric that is not easily seen to make sure the cleaner does not affect the color of the fabric.


2. For liquids: blot with a clean, soft, white cloth. For


solids: remove as much as possible and then vacuum or brush.


3. Spray a small amount of the cleaner onto a clean


soft, white, cloth. Do not apply spray directly to the fabric.


4. Start cleaning from the seams into the stain to


avoid a ring effect.


5. Continue cleaning, using a clean area of the cloth


each time it becomes soiled.


6. When the stain is removed, blot the cleaned area


with another dry, clean, soft, white cloth.


7. If the cleaner leaves a ring effect, follow up with the


club soda water instructions given earlier in this section.


5-87


Special Fabric Cleaning Problems Stains caused by such things as catsup, black coffee, egg, fruit, fruit juice, milk, soft drinks, vomit, urine, and blood can be removed using the club soda water instructions given earlier in this section. If an odor lingers after cleaning vomit or urine, treat the area with a water and baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Let dry. Stains caused by oil and grease can be cleaned with an approved GM cleaner and a clean, white cloth. 1. Carefully scrape off excess stain. 2. Clean with cool water and allow to dry completely. 3. If a stain remains, follow the “Using Cleaner on


Fabric” instructions described earlier.


Vinyl Use warm water and a clean cloth. (cid:127) Rub with a clean, damp cloth to remove dirt. This


may have to be done more than once. Things like tar, asphalt, and shoe polish will stain if they are not removed quickly. Use a clean cloth and vinyl cleaner. See your dealer for this product.


Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally. Do not use heat to dry.


For stubborn stains, use a leather cleaner.


(cid:127) Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish, or shoe polish on leather.


(cid:127) Soiled or stained leather should be cleaned


immediately. If dirt is allowed to work into the finish, it can harm the leather.


Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.


Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish.


5-88


(cid:127) (cid:127) Wood Panels Use a clean cloth moistened in warm, soapy water (use mild dish washing soap). Dry the wood immediately with a clean cloth.


Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See Vehicle Care/Appearance Materials on page 5-94. Notice: glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger and the integrated radio antenna. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner.


If you use abrasive cleaners when cleaning


Care of Safety Belts Keep belts clean and dry.


{CAUTION:


Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.


Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather frequent application may be required.


5-89


Washing Your Vehicle The paint finish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-94. Do not use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter the vehicle.


Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 5-90.


Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your dealer. See Vehicle Care/Appearance Materials on page 5-94. If your vehicle has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint finish on your vehicle.


5-90


Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint finish looking new by keeping your vehicle garaged or covered whenever possible. Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, you may use chrome polish on chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts.


Windshield, Backglass, and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with a full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn.


5-91


If you use strong soaps, chemicals,


Aluminum Wheels Notice: abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, you could damage the surface of the wheel(s). The repairs would not be covered by your warranty. Use only GM-approved cleaners on aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by your warranty. Use chrome polish on chrome wheels only. The surface of these wheels is similar to the painted surface of the vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because the surface could be damaged. Do not use chrome polish on aluminum wheels.


If you drive your vehicle through an


Notice: automatic car wash that has silicone carbide tire cleaning brushes, you could damage the aluminum or chrome-plated wheels. The repairs would not be covered by your warranty. Never drive a vehicle equipped with aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. Do not take the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels.


Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint finish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle.


5-92


Sheet Metal Damage If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty.


Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your GM dealer. Larger areas of finish damage can be corrected in your GM dealer’s body and paint shop.


Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being flushed. Your GM dealer or an underbody car washing system can do this for you.


Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs first.

Vehicle Identification


Vehicle Identification Number (VIN)


This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration. Engine Identification The eighth character in your VIN is the engine code. This code will help you identify your engine, specifications and replacement parts.


5-95


Service Parts Identification Label You will find this label on the inside of the glove box. It is very helpful if you ever need to order parts. On this label, you will find the following: (cid:127) VIN (cid:127) Model designation (cid:127) Paint information (cid:127) Production options and special equipment Be sure that this label is not removed from the vehicle.


Electrical System


Add-On Electrical Equipment Notice: Don’t add anything electrical to your vehicle unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an air bag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-57.


Headlamps The headlamp wiring is protected by an internal circuit breaker. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away.


5-96


Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow or ice, the wiper will stop until the motor cools. If the overload is caused by some electrical problem, be sure to get it fixed.


Power Windows and Other Power Options Circuit breakers protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed or goes away.


Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without— like the radio or cigarette lighter—and use its fuse, if it is the correct amperage. Replace it as soon as you can.
