Headlamp Aiming The headlamp aiming system has been preset at the factory. If the vehicle is damaged in an accident, the aim of the headlamps may be affected and adjustment may be necessary. It is recommended that a dealer/ retailer adjust the headlamps. To re-aim the headlamps yourself, use the following procedure. The vehicle should be properly prepared as follows:

The vehicle should be placed so the headlamps are 7.6 m (25 ft) from a light colored wall. The vehicle must have all four tires on a level surface which is level all the way to the wall.

.

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 75 kg (160 lbs) sitting on the driver's seat. Tires should be properly inflated.

Headlamp aiming is done with the vehicle's low-beam headlamps. The high-beam headlamps will be correctly aimed if the low-beam headlamps are aimed properly.

Vehicle Care

10-31

To adjust the vertical aim, do the following: 1. Open the hood. See Hood on

page 10‑5 for more information.

4. At the wall measure from the

ground upward (A) to the recorded distance from Step 3 and mark it.

5. Draw or tape a horizontal line (B)

on the wall the width of the vehicle at the height of the mark in Step 4.

2. Locate the aim dot on the lens of

the low‐beam headlamp.

3. Measure the distance from the

ground to the aim dot on the low‐beam headlamp. Record the distance.

Vehicle Care

Notice: Do not cover a headlamp to improve beam cut-off when aiming. Covering a headlamp may cause excessive heat build-up which may cause damage to the headlamp. 6. Turn on the low-beam

headlamps and place a piece of cardboard or equivalent in front of the headlamp not being adjusted. This allows only the beam of light from the headlamp being adjusted to be seen on the flat surface.

7. Locate the vertical headlamp

aiming screws, which are under the hood near each headlamp assembly. The adjustment screw can be turned with a E8 Torx® socket. 8. Turn the vertical aiming screw

until the headlamp beam is aimed to the horizontal tape line. Turn it clockwise or counterclockwise to raise or lower the angle of the beam.

9. Make sure that the light from the

headlamp is positioned at the bottom edge of the horizontal tape line. The lamp on the left (A) shows the correct headlamp aim. The lamp on the right (B) shows the incorrect headlamp aim.

10. Repeat Steps 7 through 9 for

the opposite headlamp.

Fuses and Circuit Breakers The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of circuit overload and fire caused by electrical problems. There are two fuse blocks — the engine compartment fuse block, and the instrument panel fuse block. To identify and check fuses and relays, refer to the Fuse Usage Chart on the inside surface of the fuse panel door.

Electrical System

Electrical System Overload The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems. Fuses and circuit breakers protect the following in the vehicle: . Headlamp Wiring . Windshield Wiper Motor . Power Windows and other

Power Accessories

Headlamp Wiring An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off. Windshield Wipers If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart. Although the circuit is protected from electrical overload, overload due to heavy snow or ice, may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.

10-38

Vehicle Care

Engine Compartment Fuse Block The engine compartment fuse block is located on the driver side of the engine compartment, near the battery. Notice: Spilling liquid on any electrical components on the vehicle may damage it. Always keep the covers on any electrical component.

Vehicle Care

10-43

WARNING (Continued)

. 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.

. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.

See Tire Pressure for High-Speed Operation on page 10‑52 for inflation pressure adjustment for high speed driving.

{ WARNING

Poorly maintained and improperly used tires are dangerous.

. Overloading your tires can

cause overheating as a result of too much flexing. You could have an air-out and a serious accident. See Vehicle Load Limits on page 9‑22.

. 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 Tire Pressure on page 10‑50.

10-50

Vehicle Care

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 . Premature or irregular wear . Poor handling . Reduced fuel economy

If your tires have too much air (over‐inflation), you can get the following:

. Unusual wear . Poor handling . Rough ride . Needless damage from

road hazards

A vehicle specific Tire and Loading Information label is attached to your vehicle. 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 Vehicle Load Limits on page 9‑22 . How you load your vehicle affects vehicle handling and ride comfort. Never load your vehicle with more weight than it was designed to carry.

Vehicle Care

10-51

If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Re‐check 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.

When to Check Check your tires once a month or more. Do not forget to check the compact spare tire, if the vehicle has one. The compact spare should be at 60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire on page 10‑73 .

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 under‐inflated.

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 1.6 km (1 mile). 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.

10-52

Vehicle Care

Tire Pressure for High-Speed Operation

{ WARNING

Driving at high speeds, 160 km/h (100 mph) or higher, puts an additional strain on tires. Sustained high-speed driving causes excessive heat build up and can cause sudden tire failure. You could have a crash and you or others could be killed. Some high-speed rated tires require inflation pressure adjustment for high speed operation. When speed limits and road conditions are such that a vehicle can be driven at high speeds, make sure the tires are rated for high speed operation, in excellent condition, and set to the correct cold tire inflation pressure for the vehicle load.

If your vehicle has P235/55R18 size tires, they will require inflation pressure adjustment when driving your vehicle at speeds of 160 km/h (100 mph) or higher. Set the cold inflation pressure to the maximum inflation pressure shown on the tire sidewall, or 262 kPa (38 psi), whichever is lower. See the example following. When you end this high-speed driving, return the tires to the cold tire inflation pressure shown on the Tire and Loading Information label. See Vehicle Load Limits on page 9‑22 and Tire Pressure on page 10‑50. Example: You will find the maximum load and inflation pressure molded on the tire's sidewall, in small letters, near the rim flange. It will read something like this: Maximum load 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.

For this example, you would set the inflation pressure for high‐speed driving at 262 kPa (38 psi).

Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your vehicle's tires and 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. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start‐ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.

Vehicle Care

10-53

Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. See Tire Pressure Monitor Operation on page 10‑54 for additional information. Federal Communications Commission (FCC) and Industry and Science Canada See Radio Frequency Statement on page 13‑16 for information regarding Part 15 of the Federal Communications Commission (FCC) Rules and RSS-210/211 of Industry and Science Canada.

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under‐inflated. Accordingly, when the low tire pressure telltale illuminates, 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. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under‐inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

10-54

Vehicle Care

Tire Pressure Monitor Operation This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the vehicle's tires and transmit the tire pressure readings to a receiver located in the vehicle.

When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light on the instrument panel cluster.

The low tire pressure warning light comes on at each ignition cycle until the tires are inflated to the correct inflation pressure. The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as you start to drive. This may be an early indicator that the air pressure in the tire(s) are getting low and need to be inflated to the proper pressure. 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 Vehicle Load Limits on page 9‑22 , for an example of the Tire and Loading Information label and its location on your vehicle. Also see Tire Pressure on page 10‑50. Your vehicle's TPMS system can warn you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection on page 10‑57, Tire Rotation on page 10‑57 and Tires on page 10‑43. Notice: Liquid tire sealants could damage the Tire Pressure Monitor System (TPMS) sensors. Sensor damage caused by using a tire sealant is not covered by your warranty. Do not use liquid tire sealants.

TPMS Malfunction Light The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. When the system detects a malfunction, the low tire warning light flashes for about one minute and then stays on for the remainder of the ignition cycle. The TPMS malfunction light comes on at each ignition cycle until the problem is corrected. Some of the conditions that can cause the malfunction light to come on are: . One of the road tires has been

replaced with the spare tire. The spare tire does not have a TPMS sensor. The TPMS malfunction light should go off once you re‐install the road tire containing the TPMS sensor.

The TPMS sensor matching process was started but not completed or not completed successfully after rotating the vehicle's tires. The TPMS malfunction light should go off once the TPMS sensor matching process is performed successfully. See “TPMS Sensor Matching Process” later in this section.

. One or more TPMS sensors are missing or damaged. The TPMS malfunction light should go off when the TPMS sensors are installed and the sensor matching process is performed successfully. See your dealer/ retailer for service.

. Replacement tires or wheels do not match your vehicle's original equipment tires or wheels. Tires and wheels other than those recommended for your vehicle could prevent the TPMS from functioning properly. See Buying New Tires on page 10‑59.

. Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction.

Vehicle Care

TPMS Sensor Matching Process Each TPMS sensor has a unique identification code. Any time you replace one or more of the TPMS sensors or rotate the vehicle's tires, 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: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service. The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire's air pressure. When increasing the tire's pressure, do not exceed the maximum inflation pressure indicated on the tire's sidewall.

To decrease the tire's air-pressure use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. You have two minutes to match each tire and wheel position. If it takes longer than two minutes to match any tire and wheel position, the matching process stops and you will need to start over. The TPMS matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to

ON/RUN with the engine off.

3. Press and hold the RKE

transmitter's Lock and Unlock buttons at the same time, for about three seconds. The horn will sound twice to indicate the receiver is ready for the sensor matching process to begin.

4. Start with the driver side front tire. The driver side turn signal lamp comes on.

5. Remove the valve cap from the

tire's valve stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which may take up to 30 seconds to sound, confirms that the sensor identification code has been matched to the tire/wheel position.

6. Proceed to the passenger side

front tire. The passenger side front turn signal lamp comes on. Repeat the procedure in Step 5.

7. Proceed to the passenger side

rear tire. The passenger side rear turn signal lamp comes on. Repeat the procedure in Step 5.

8. Proceed to the driver side rear

tire. The driver side rear turn signal lamp comes on. Repeat the procedure in Step 5. The horn sounds two times to indicate the sensor identification code has been matched to the driver side rear tire, and the TPMS sensor matching process is no longer active.

9. Turn the ignition switch to

LOCK/OFF.

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.

Tire Inspection We recommend that you regularly inspect your vehicle's tires, including the spare tire, if the vehicle has one, for signs of wear or damage. See When It Is Time for New Tires on page 10‑58 for more information.

Tire Rotation Tires should be rotated every 8 000 to 13 000 km (5,000 to 8,000 miles). See Scheduled Maintenance on page 11‑2 . The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that the vehicle continues to perform most like it did when the tires were new.

Vehicle Care

10-57

Any time you notice unusual wear, rotate the 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 10‑58 and Wheel Replacement on page 10‑64 .

When rotating the vehicle's tires, always use the correct rotation pattern shown here.

10-58

Vehicle Care

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 Tire Pressure on page 10‑50 and Vehicle Load Limits on page 9‑22 . Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation on page 10‑54 . Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 12‑2 .

{ WARNING

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 changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, 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 If a Tire Goes Flat on page 10‑65.

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 appear when the tires have only 1.6 mm (1/16 inch) or less of tread remaining.

The vehicle needs new tires if any of the following statements are true: . You can see the indicators at three or more places around the tire.

. 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. This is also true for the spare tire, if the vehicle has one, even if it is not being used. Multiple conditions affect how fast this aging takes place, including

temperatures, loading conditions, and inflation pressure maintenance. With proper care and maintenance tires typically wear out before they degrade due to age. If you are unsure about the need to replace the tires as they get older, consult the tire manufacturer for more information.

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.

Vehicle Care

10-59

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 10‑44
for additional information.

10-60

Vehicle Care

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 on page 10‑57
and Tire Rotation on page 10‑57
for information on proper tire rotation.

{ WARNING

{ WARNING

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 10‑73 .

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.

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, rollover airbags, traction control, and stability control, the performance of these systems can be affected.

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 10‑52 . Your vehicle's original equipment tires are listed on the Tire and Loading Information Label. See Vehicle Load Limits on page 9‑22 , for more information about the Tire and Loading Information Label and its location on your vehicle.

Vehicle Care

10-61

{ WARNING 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 10‑59 and Accessories and Modifications on page 10‑3 for additional information.

Vehicle Care

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 25 to 30 cm (10 to 12 inches), 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.

Vehicle Care

10-63

Wheel Alignment and Tire Balance The tires and wheels on the vehicle were aligned and balanced carefully at the factory to give 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 there is unusual tire wear or the vehicle pulls to one side or the other, the alignment should be checked. If the vehicle vibrates when driving on a smooth road, the tires and wheels might need to be rebalanced. See your dealer/retailer for proper diagnosis.

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.

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. It should be noted that 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.

Vehicle Care

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. 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.

{ WARNING

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 If a Tire Goes Flat on page 10‑65 for more information.

Used Replacement Wheels

{ WARNING

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.

Tire Chains

{ WARNING

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,
