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 5-66
and Wheel Replacement on page 5-71.5-64
When rotating the vehicle’s tires, always use the correct rotation pattern shown here. Do not include the compact spare tire 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. See Inflation - Tire Pressure on page 5-58 and Loading the Vehicle on page 4-24.
Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation on page 5-61. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 5-104.
{ CAUTION:
Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after 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 5-74.

When It Is Time for New Tires Various factors, such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions influence when you need 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.
You need new tires if any of the following statements are true: (cid:129) You can see the indicators at three or more places
around the tire.
(cid:129) 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.
The rubber in tires degrades over time, even if they are not being used. This is also true for the spare tire, if your vehicle has one. Multiple conditions affect how fast this aging takes place, including temperatures, loading conditions, and inflation pressure maintenance. With proper care and maintenance tires will typically wear out before they degrade due to age. If you are unsure about the need to replace your tires as they get older, consult the tire manufacturer for more information.

(cid:129) (cid:129) (cid:129) 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 near the tire size. If the tires have an all-season tread design, the TPC Spec number will be followed by an MS for mud and snow. See Tire Sidewall Labeling on page 5-52 for additional information.
GM recommends replacing tires in sets of four. This is because uniform tread depth on all tires will help keep your vehicle performing most like it did when the tires were new. Replacing less than a full set of tires can affect the braking and handling performance of your vehicle. See Tire Inspection and Rotation on page 5-64
for information on proper tire rotation.{ 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 all wheels. It is all right to drive with your compact spare temporarily, as it was developed for use on your vehicle. See Compact Spare Tire on page 5-84.
5-67
{ CAUTION:
If you use bias-ply tires on the 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 the vehicle.
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 that have a tire pressure monitoring system could 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 5-59. Your vehicle’s original equipment tires are listed on the Tire and Loading Information Label. See Loading the Vehicle on page 4-24, for more information about the Tire and Loading Information Label and its location on your vehicle.
5-68
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, anti-lock brakes, traction control, and 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 Saturn specific wheel and tire systems developed for your vehicle, and have them properly installed by a Saturn certified technician.
See Buying New Tires on page 5-67 and Accessories and Modifications on page 5-3 for additional information.
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 (NHTSA), 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 (UTQG) 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.
5-69
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.
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.
5-70
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/retailer if any of these conditions exist. Your dealer/retailer 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.
{ 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 might need to be checked. If you notice your vehicle vibrating when driving on a smooth road, the tires and wheels might need to be rebalanced. See your dealer/retailer for proper diagnosis.
5-71
If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new Saturn 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 5-74 for more information. Used Replacement Wheels
{ 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 Saturn original equipment wheel.
5-72
Tire Chains
{ CAUTION:
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 the 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 the vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to the vehicle, drive slowly, readjust or remove the

device if it is contacting the vehicle, and do not spin the vehicle’s wheels. If you do find traction devices that will fit, install them on the front tires.
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 creates 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.
5-73
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.
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 vehicle’s hazard warning flashers. See Hazard Warning Flashers on page 3-6 for more information.
{ 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.
{ 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 the shift lever in P (Park). 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:

CAUTION:
(Continued)
To be even more certain the vehicle will not move, you should 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.
When your vehicle has a flat tire, use the following example as a guide to assist you in the placement of wheel blocks.
Removing the Spare Tire and Tools The equipment you will need is located in the trunk. 1. Open the trunk. See Trunk on page 2-12 for more
information.
2. Lift the handle on the spare tire cover. The handle
can hook on the front edge of the trunk’s weatherstrip to hold the cover out of the way.
The following information tells you how to use the jack and change a tire.
3. Turn the wing nut counterclockwise and remove it. Then remove the compact spare tire. See Compact Spare Tire on page 5-84 for more information. 4. Remove the wing nut holding the jack in place.

Removing the Flat Tire and Installing the Spare Tire 1. Do a safety check before proceeding. Please
see Changing a Flat Tire on page 5-74 for more information.
2. If your vehicle has a wheel cover or hubcap that has plastic wheel nut caps, then loosen the plastic nut caps. You might need to use the wheel wrench to loosen them. Do not pry off wheel covers or center caps that have plastic wheel nut caps.
3. Remove the wheel cover or center cap from the
wheel to locate the wheel nuts. If your vehicle has a wheel cover or hubcap without plastic wheel nut caps, carefully pry on the edge of the plastic wheel trim to remove it from the wheel to find the wheel nuts. Store the wheel cover in the trunk until you have the flat repaired or replaced.
5-77
4. Use the wheel wrench to loosen all the wheel nuts.
Do not remove them yet.
5. Position the lift head at the jack location nearest the flat tire. Make sure all of the jack lift head is touching the jacking flange under the body. Do not place the jack under a body panel. The lower body panel has an arrow to aid in locating the jacking location.
6. Put the compact spare tire near the flat tire.
5-78
{ 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.
{ 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.
7. Raise the vehicle by turning the wheel wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit underneath the wheel well.
5-79
8. Remove all of the
wheel nuts.
{ CAUTION:
Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after 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 5-74.
9. Remove the flat tire.

Storing a Flat or Spare Tire and Tools
{ 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.
To store the flat tire and jack in the compact spare tire compartment: 1. Open the trunk. See Trunk on page 2-12 for more
information.
2. Remove the bolt extension (in the yellow sleeve) from the jack and remove the center cap from the wheel.
3. Place the jack over the bolt (A) on the floor, making
sure it contacts the bolt as shown, and thread the jack retainer nut until it contacts the jack.
4. With the valve stem up, place the tire on the
compartment floor with the rear of the tire beneath the trim panel (tire may not lay completely flat).
5. Line up the center hole of the wheel with the bolt. 6. With the yellow cap in place to prevent the wheel from being scratched, screw the bolt extension onto the bolt through the wheel nut hole.
7. Remove the yellow cap from the bolt extension. 8. Secure the tire and wheel with the larger wing nut.
5-83
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.

Appearance Care
Interior Cleaning 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. When cleaning your vehicle’s interior, only use cleaners specifically designed for the surfaces being cleaned. Permanent damage may result from using cleaners on
If you use abrasive cleaners when cleaning
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 dealer/retailer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your dealer/retailer to remove odors from your vehicle’s upholstery.
5-85
Do not clean your vehicle using: (cid:129) A knife or any other sharp object to remove a soil
from any interior surface.
(cid:129) A stiff brush. It can cause damage to your vehicle’s
interior surfaces.
(cid:129) Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage your interior and does not improve the effectiveness of soil removal. Laundry detergents or dishwashing soaps with degreasers can leave residue that streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.78 L) of water is a good guide. Use only mild, neutral-pH soaps. Too much cleaner that saturates the upholstery.
(cid:129) Organic solvents such as naptha, alcohol, etc. that
can damage your vehicle’s interior.
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 any soil, always try to remove it 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.
5-86
(cid:129) (cid:129) (cid:129) (cid:129) To clean: 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.
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.
5-87
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.
Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often. Notice: Certain cleaners contain chemicals that can damage the emblems or nameplates on your vehicle. Check the cleaning product label. If it states that it should not be used on plastic parts, do not use it on your vehicle or damage may occur and it would not be covered by the warranty. Do not wash the vehicle in direct sunlight. Use a car washing soap. Do not use cleaning agents that are petroleum based or that contain acid or abrasives, as they can damage the paint, metal or plastic on your vehicle. Approved cleaning products can be obtained from your dealer/retailer. Follow all manufacturers’ directions regarding correct product usage, necessary safety precautions and appropriate disposal of any vehicle care product. Rinse the vehicle well, before washing and after to remove all cleaning agents completely. If they are allowed to dry on the surface, they could stain. Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting.
5-88
High pressure car washes may cause water to enter the vehicle. Avoid using high pressure washes closer than 12 inches (30 cm) to the surface of the vehicle. Use of power washers exceeding 1,200 psi (8 274 kPa) can result in damage or removal of paint and decals.
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 5-88.
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 approved cleaning products from your dealer/retailer. 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. 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.
5-89
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 and Wiper Blades Clean the outside of the windshield with glass cleaner. Clean the rubber blades using a lint free cloth or paper towel soaked with windshield washer fluid or a mild detergent. Wash the windshield thoroughly when cleaning the blades. Bugs, road grime, sap, and a buildup of vehicle wash/wax treatments may cause wiper streaking. Replace the wiper blades if they are worn or damaged. Wipers can be damaged by: (cid:129) Extreme dusty conditions (cid:129) Sand and salt (cid:129) Heat and sun (cid:129) Snow and ice, without proper removal
5-90
If you use strong soaps, chemicals,
Aluminum Wheels Notice: Chrome wheels and other chrome trim may be damaged if you do not wash your vehicle after driving on roads that have been sprayed with magnesium, calcium or sodium chloride. These chlorides are used on roads for conditions such as ice and dust. Always wash your vehicle’s chrome with soap and water after exposure. 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 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. Notice: If you drive your vehicle through an 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.
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.
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 vehicle 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 dealer/retailer. Larger areas of finish damage can be corrected in your dealer’s/retailer’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/retailer 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, we 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.

Electrical System
Add-On Electrical Equipment Notice: Do not add anything electrical to your vehicle unless you check with your dealer/retailer first. Some electrical equipment can damage your vehicle and the damage would not be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Add-on equipment can drain your vehicle’s battery, even if your vehicle is not operating. Your vehicle has an airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-70.
Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it fixed.
5-94
Power Windows and Other Power Options Fuses in the fuse block protect the power windows. When the current load is too heavy, the fuse opens protecting the circuit until the problem is fixed.
Fuses The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible links. This greatly reduces the chance of damage 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 to replace a bad fuse with a new one of the identical size and rating. There are three fuse blocks in your vehicle: one in the center of the instrument panel, one in the engine compartment and one in the trunk. There is a fuse puller located on the instrument panel fuse block. It can be used to easily remove fuses from the fuse block.
Instrument Panel Fuse Block
The instrument panel fuse block is located on the passenger side of the vehicle, on the lower portion of the instrument panel near the floor. Remove the panel cover to access the fuse block, then remove the fuse block cover to access the fuses.

Maintenance Schedule
Introduction Important: Keep engine oil at the proper level and change as recommended.
Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts, and recommended fluids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance might not be covered by warranty.
Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance is important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, be sure to maintain your vehicle properly.
6-2
Using the Maintenance Schedule We want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You might drive very short distances only a few times a week. Or you might drive long distances all the time in very hot, dusty weather. You might use your vehicle in making deliveries. Or you might drive it to work, to do errands, or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You might need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your dealer/retailer. This schedule is for vehicles that:
carry passengers and cargo within recommended limits. You will find these limits on the Tire and Loading Information label. See Loading the Vehicle on page 4-24. are driven on reasonable road surfaces within legal driving limits. use the recommended fuel. See Gasoline Octane on page 5-6.
(cid:129) (cid:129) (cid:129) The services in Scheduled Maintenance on page 6-4
should be performed when indicated. See Additional Required Services on page 6-6 and Maintenance Footnotes on page 6-7 for further information.{ CAUTION:
Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your dealer/retailer to have a qualified technician do the work. See Doing Your Own Service Work on page 5-4.
Some maintenance services can be complex. So, unless you are technically qualified and have the necessary equipment, you should have your dealer/retailer do these jobs.
When you go to your dealer/retailer for your service needs, you will know that trained and supported service technicians will perform the work using genuine parts. If you want to purchase service information, see Service Publications Ordering Information on page 7-16. Owner Checks and Services on page 6-9 tells you what should be checked, when to check it, and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, fluids, and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-12 and Maintenance Replacement Parts on page 6-13. When your vehicle is serviced, make sure these are used. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. We recommend the use of genuine parts from your dealer/retailer.
6-3
Scheduled Maintenance When the CHANGE OIL SOON message in the Driver Information Center (DIC) comes on, it means that service is required for your vehicle. Have your vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer/ retailer has trained service technicians who will perform this work using genuine parts and reset the system. If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 5-23 for information on the Engine Oil Life System and resetting the system.
When the CHANGE OIL SOON message appears, certain services, checks, and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that your first service be Maintenance I, your second service be Maintenance II, and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II might be required more often. Maintenance I — Use Maintenance I if the message comes on within 10 months since the vehicle was purchased or Maintenance II was performed. Maintenance II — Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the message comes on 10 months or more since the last service or if the message has not come on at all for one year.

(j) A fluid loss in any vehicle system could indicate a problem. Have the system inspected and repaired and the fluid level checked. Add fluid if needed. (k) If you drive regularly under dusty conditions, inspect the filter at each engine oil change. (l) Change automatic transmission fluid if the vehicle is mainly driven under one or more of these conditions:− In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
− In hilly or mountainous terrain. − When doing frequent trailer towing. − Uses such as found in taxi, police, or delivery
service.
If you do not use your vehicle under any of these conditions, the fluid does not require changing. (m) Visually inspect belt for fraying, excessive cracks, or obvious damage. Replace belt if necessary.
Owner Checks and Services These owner checks and services should be performed at the intervals specified to help ensure vehicle safety, dependability, and emission control performance. Your dealer/retailer can assist with these checks and services. Be sure any necessary repairs are completed at once. Whenever any fluids or lubricants are added to the vehicle, make sure they are the proper ones, as shown in Recommended Fluids and Lubricants on page 6-12.
At Each Fuel Fill It is important to perform these underhood checks at each fuel fill. Engine Oil Level Check Notice: regularly and keep it at the proper level. Failure to keep the engine oil at the proper level can cause damage to the engine not covered by the vehicle warranty. Check the engine oil level and add the proper oil if necessary. See Engine Oil on page 5-20.
It is important to check the engine oil
Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 5-27. Windshield Washer Fluid Level Check Check the windshield washer fluid level in the windshield washer fluid reservoir and add the proper fluid if necessary.
At Least Once a Month Tire Inflation Check Inspect the vehicle’s tires and make sure they are inflated to the correct pressures. Do not forget to check the spare tire. See Inflation - Tire Pressure on page 5-58. Check to make sure the spare tire is stored securely. See Changing a Flat Tire on page 5-74. Tire Wear Inspection Tire rotation may be required for high mileage highway drivers prior to the Engine Oil Life System service notification. Check the tires for wear and, if necessary, rotate the tires. See Tire Inspection and Rotation on page 5-64.
