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.
{CAUTION:
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.

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. Your vehicle has a remote negative (−) terminal for this purpose.
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.
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.

Headlamp Aiming The vehicle has a visual optical headlamp aiming system. The aim has been preset at the factory and should need no further adjustment. However, if the vehicle is damaged in an accident, the headlamp aim may be affected and adjustment may be necessary. If oncoming vehicles flash their high beams at you, this may also mean the vertical aim needs to be adjusted. It is recommended that the vehicle is taken to your dealer for service if the headlamps need to be re-aimed. It is possible however, to re-aim the headlamps as described in the following procedure.
The vehicle should be properly prepared as follows: The vehicle should be placed so the headlamps are 25 ft. (7.6 m) from a light colored wall or other flat surface. The vehicle must have all four tires on a level surface which is level all the way to the wall or other flat surface. The vehicle should be placed so it is perpendicular to the wall or other flat surface. The vehicle should not have any snow, ice, or mud on it. The vehicle should be fully assembled and all other work stopped while headlamp aiming is being performed. The vehicle should be normally loaded with a full tank of fuel and one person or 160 lbs (75 kg) sitting on the driver’s seat. Tires should be properly inflated. The spare tire is in its original location in the vehicle.

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 4-52. 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.
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
5-60
(cid:127) (cid:127) (cid:127) 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.
Tire Pressure Monitor System Your vehicle is equipped with a Tire Pressure Monitor System (TPMS). This system uses radio and sensor technology to check tire pressure levels. TPMS sensors are mounted onto each tire and wheel assembly on your vehicle, including the spare tire. The TPMS sensors transmit tire pressure readings to a receiver located in the vehicle. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label.
When the low tire pressure telltale is illuminated, one or more of your tires is significantly under-inflated.
You should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
5-61
When a low tire pressure condition is detected, the TPMS will illuminate the low tire pressure warning symbol on the instrument panel cluster, and at the same time display the LOW TIRE message on the Driver Information Center (DIC). The message will appear at each ignition cycle until the tires are inflated to the correct inflation pressure. For additional information and details about the DIC operation and displays see DIC Controls and Displays on page 3-41 and DIC Warnings and Messages on page 3-44. A Tire and Loading Information label, attached to your vehicle, shows the size of your vehicle’s original equipment tires and the correct inflation pressure for your vehicle’s tires when they are cold. See Loading Your Vehicle on page 4-52, for an example of the tire information label and its location on your vehicle. Also see Inflation - Tire Pressure on page 5-60 for additional information. Your vehicle’s TPMS can warn you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation on page 5-64, When It Is Time for New Tires on page 5-65, and Tires on page 5-53.
Notice: Do not use a tire sealant if your vehicle is equipped with Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors. The SERV (Service) TPM message is displayed when the TPMS system is malfunctioning. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed. See your dealer for service, TPMS Sensor Identification Codes Each TPMS sensor has a unique identification code. Any time you rotate your vehicle’s tires or replace one or more of the TPM sensors, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched to the tire/wheel positions in the following order: left front (LF), right front (RF), right rear (RR) and left rear (LR). You will have one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over.

6. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 5.
7. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 5.
8. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the left rear tire, check to see if the TPMS warning light is still flashing. If yes, turn the ignition switch to LOCK. 10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading Information label.
11. Put the valve caps back on the valve stems.
The TPM sensor matching procedure is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to ON with the engine off. 3. Turn the exterior lamp switch from AUTO to
ON four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicates the TPM matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The SERV TPM message will be displayed on the Driver Information Center (DIC).
4. Start with the left (driver’s side) front tire. 5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or decreasing the tire’s air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with step number one. To let air-pressure out of a tire you can use the pointy end of the valve cap, a pencil-style air pressure gage or a key.
5-63

This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received
including interference that may cause undesired operation of the device.
Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment.
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. 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 Scheduled Maintenance on page 6-4.
When rotating your vehicle’s tires, always use one of the correct rotation patterns shown here.
5-64
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 4-52. 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 needed, to get all the rust or dirt off. See Changing a Flat Tire on page 5-73.
Any time you rotate the vehicle’s tires the Tire Pressure Monitor System (TPMS) will need to be reset. The TPMS identification codes will need to be matched to tire and wheel position. See “TPMS Sensor Identification Codes” under Tire Pressure Monitor System on page 5-61.
When It Is Time for New Tires
One way to tell when it is 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 cannot be repaired well because of the size or location of the damage.
5-65
(cid:127) (cid:127) (cid:127) Buying New Tires GM has developed and matched specific tires for your vehicle. The original equipment tires installed on your vehicle, when it was new, were designed to meet General Motors Tire Performance Criteria Specification (TPC spec) system rating. If you need replacement tires, GM strongly recommends that you get tires with the same TPC Spec rating. This way, your vehicle will continue to have tires that are designed to give the same performance and vehicle safety, during normal use, as the original tires. GM’s exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of your vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM’s TPC Spec number is molded onto the tire’s sidewall by the tire manufacturer. If the tires have an all-season tread design, the TPC spec number will be followed by a MS, for mud and snow. See Tire Sidewall Labelling on page 5-54 for additional information.
{CAUTION:
Mixing tires could cause you to lose control while driving. If you mix tires of different sizes, brands, or types (radial and bias-belted tires) the vehicle may not handle properly, and you could have a crash. Using tires of different sizes, brands, or types may also cause damage to your vehicle. Be sure to use the correct size, brand, and type of tires on your vehicle’s wheels.
{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
If you must replace your vehicle’s tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias-belted tires) as your vehicle’s original tires. Vehicles equipped with a tire pressure monitoring system may give an inaccurate low-pressure warning if non-TPC spec rated tires are installed on your vehicle. Non-TPC Spec rated tires may give a low-pressure warning that is higher or lower than the proper warning level you would get with TPC Spec rated tires. See Tire Pressure Monitor System on page 5-61. Your vehicle’s original equipment tires are listed on the Tire and Loading Information Label. This label is attached to the vehicle’s center pillar (B-pillar). See Loading Your Vehicle on page 4-52, for more information about the Tire and Loading Information Label.
Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this may affect the way your vehicle performs, including its braking, ride and handling characteristics, stability and resistance to rollover. Additionally, if your vehicle has electronic systems such as, antilock brakes; traction control; and electronic stability control, the performance of these systems can be affected.
{CAUTION:
If you add different sized wheels, your vehicle may not provide an acceptable level of performance and safety if tires not recommended for those wheels are selected. You may increase the chance that you will crash and suffer serious injury. Only use GM specific wheel and tire systems developed for your vehicle, and have them properly installed by a GM certified technician.
See Buying New Tires on page 5-66 and Accessories and Modifications on page 5-3 for additional information.
5-67
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.
5-68
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 Alignment and Tire Balance The tires and wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing will not be necessary on a regular basis. However, if you notice unusual tire wear or your vehicle pulling to one side or the other, the alignment may need to be checked. If you notice your vehicle vibrating when driving on a smooth road, your tires and wheels may need to be rebalanced. See your dealer for proper diagnosis.
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.
5-69
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.
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 5-73 for more information. Used Replacement Wheels
{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.
{CAUTION:
Putting a used wheel on your vehicle is dangerous. You cannot know how it has been used or how far it has been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel.
5-70
If your vehicle has a tire size other than
Notice: LT285/75R16 use tire chains only where legal and only when you must. Use chains that are the proper size for your tires. Install them on the tires of the rear axle. Do not use chains on the tires of the front axle. Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle.
Tire Chains
{CAUTION:
If your vehicle has LT285/75R16 size tires, do not use tire chains. They can damage your vehicle because 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, readjust or remove the device if it is contacting your vehicle, and do not spin your vehicle’s wheels. If you do find traction devices that will fit, install them on the rear tires.
5-71
If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain your vehicle’s tires properly. If air goes out of a tire, it is 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 would 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 the jacking equipment to change a flat tire safely.
5-72
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). (Continued)
CAUTION:

3. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear – not in NEUTRAL.
4. Turn off the engine and do not restart
while the vehicle is raised.
5. Do not allow passengers to remain in the
vehicle.
To be even more certain the vehicle will not move, put 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.
5-73
When you have a flat tire, you will first need to set up the wheel blocks before changing it. They are located in the tool bag, in the swing-gate. See Removing the Spare Tire and Tools on page 5-75 for more information.

Spare Tire Your vehicle, when new, had a fully-inflated spare tire. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure on page 5-60 and Loading Your Vehicle on page 4-52
for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Changing a Flat Tire on page 5-73 and Removing the Flat Tire and Installing the Spare Tire on page 5-77. 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 that were originally installed on your vehicle. This spare tires 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.4. Reinstall the wing nut retainer to fasten the jack
and tool bag in the storage compartment. Make sure that the wing nut passes through the tool bag and the jack before you tighten it.
5. Turn the wing nut retainer clockwise to secure. 6. Reinstall the compartment cover by inserting
the locator tabs in the holes in the swing-gate. Push the latches down to secure.

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) Benzene (cid:127) Naphtha (cid:127) Carbon Tetrachloride (cid:127) Acetone (cid:127) Paint Thinner
Turpentine Lacquer Thinner
(cid:127) Nail Polish Remover They can all be hazardous — some more than others — and they can all damage the vehicle, too.
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
Cleaning the Inside of Your Vehicle Your vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on your upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from your upholstery. It is important to keep your upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible. Your vehicle’s interior may experience extremes of heat that could cause stains to set rapidly. Lighter colored interiors may require more frequent cleaning. Use care because newspapers and garments that transfer color to your home furnishings may also transfer color to your vehicle’s interior.
5-85
(cid:127) (cid:127) (cid:127) If you use abrasive cleaners when cleaning
When cleaning your vehicle’s interior, only use cleaners specifically designed for the surfaces being cleaned. Permanent damage may result from using cleaners on surfaces for which they were not intended. Use glass cleaner only on glass. Remove any accidental over-spray from other surfaces immediately. To prevent over-spray, apply cleaner directly to the cleaning cloth. Notice: glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. Many cleaners contain solvents that may become concentrated in your vehicle’s breathing space. Before using cleaners, read and adhere to all safety instructions on the label. While cleaning your vehicle’s interior, maintain adequate ventilation by opening your vehicle’s doors and windows. Dust may be removed from small buttons and knobs using a small brush with soft bristles. Your GM dealer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your GM dealer to remove odors from your vehicle’s upholstery.
Do not clean your vehicle using the following cleaners or techniques: (cid:127) Never use a knife or any other sharp object to
remove a soil from any interior surface.
(cid:127) Never use a stiff brush. It can cause damage to
your vehicle’s interior surfaces.
(cid:127) Never apply heavy pressure or rub aggressively
with a cleaning cloth. Use of heavy pressure can damage your interior and does not improve the effectiveness of soil removal.
(cid:127) Use only mild, neutral-pH soaps. Avoid laundry
detergents or dishwashing soaps with degreasers. Using too much soap will leave a residue that leaves streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.78 L) of water is a good guide.
(cid:127) Do not heavily saturate your upholstery while
cleaning.
(cid:127) Damage to your vehicle’s interior may result from the use of many organic solvents such as naptha, alcohol, etc.
5-86
Fabric/Carpet Use a vacuum cleaner with a soft brush attachment frequently to remove dust and loose dirt. A canister vacuum with a beater bar in the nozzle may only be used on floor carpet and carpeted floor mats. For soils, always try to remove them first with plain water or club soda. Before cleaning, gently remove as much of the soil as possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper towel. Allow the soil to absorb into the paper towel until no more can be removed. For solid dry soils: remove as much as possible and then vacuum.
To clean, use the following instructions: 1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture. 3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process that was used with plain water.
If any of the soil remains, a commercial fabric cleaner or spot lifter may be necessary. When a commercial upholstery cleaner or spot lifter is to be used, test a small hidden area for colorfastness first. If the locally cleaned area gives any impression that a ring formation may result, clean the entire surface. After the cleaning process has been completed, a paper towel can be used to blot excess moisture from the fabric or carpet.
Leather A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a soft cloth dampened with a mild soap solution can be used. Allow the leather to dry naturally. Do not use heat to dry. Never use steam to clean leather. Never use spot lifters or spot removers on leather. Many commercial leather cleaners and coatings that are sold to preserve and protect leather may permanently change the appearance and feel of your leather and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Never use shoe polish on your leather.
5-87
(cid:127) (cid:127) Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of your interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Some commercial products may increase gloss on your instrument panel. The increase in gloss may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.
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. See Recommended Fluids and Lubricants on page 6-12.
5-88
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 5-93. 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 5-89.
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 5-93. 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.
5-89
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.
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.
5-90
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.
5-91
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 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 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 the VIN is the engine code. This code will help you identify your vehicle’s engine, specifications, and replacement parts.
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 airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-64.
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. Power and Heated Seat Circuit Breakers There is a circuit breaker located underneath the driver’s side front seat that controls the power and heated seat functions.
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 do not 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.
