It is recommended that the vehicle is taken to your dealer for service if the headlamps need to be adjusted. It is possible however, to re-aim the headlamps as described in the following procedure. The vehicle should be properly prepared as follows: (cid:127) The vehicle should be placed so the headlamps are 25 ft. (7.6 m) from a light colored wall. (cid:127) The vehicle must have all four tires on a level surface which is level all the way to the wall. (cid:127) The vehicle should be placed so it is perpendicular to the wall. (cid:127) The vehicle should not have any snow, ice or mud on it. (cid:127) The vehicle should be fully assembled and all other work stopped while headlamp aiming is being performed. (cid:127) 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. (cid:127) Tires should be properly inﬂated. (cid:127) The spare tire is in its proper location in the vehicle. 377 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. To adjust the vertical aim, do the following: 1. Open the hood. See Hood Release on page 333 for more information. 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. 378 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. 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. Do not place directly on the headlamp. This allows only the beam of light from the headlamp being adjusted to be seen on the ﬂat surface. 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. 7. Locate the vertical headlamp aiming screws, which are under the hood near each headlamp assembly. The adjustment screw can be turned with a 6 mm male hex. 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. 379 Taillamps, Turn Signal, Stoplamps and Sidemarker Lamps A. Sidemarker Lamp B.

Windshield Wiper Blade Replacement Windshield wiper blades should be inspected for wear or cracking. See Scheduled Maintenance on page 442. It is a good idea to clean or replace the wiper blade assembly on a regular basis or when worn. For proper windshield wiper blade length and type, see Normal Maintenance Replacement Parts on page 453. 383 To replace the wiper blade assembly, do the following: 1. Turn the ignition to ACCESSORY, with the engine off. 2. Pull the windshield wiper assembly away from the windshield. 3. Squeeze the tabs on each side of the wiper blade assembly and slide the assembly off the end of the wiper arm. 384 4. Replace the blade assembly with a new one. Allowing the wiper blade arm to touch the windshield when no wiper blade is installed could damage the windshield. Any damage that occurs would not be covered by your warranty. Do not allow the wiper blade arm to touch the windshield. 5. Repeat the steps for the other wiper. Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. For additional information refer to the tire manufacturer’s booklet included with your vehicle. {CAUTION: Poorly maintained and improperly used tires are dangerous. (cid:127) Overloading your vehicle’s tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See Loading Your Vehicle on page 307. CAUTION: (Continued) CAUTION: (Continued) (cid:127) Underinﬂated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your vehicle’s tires are cold. See Inﬂation - Tire Pressure on page 392. (cid:127) Overinﬂated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when you hit a pothole. Keep tires at the recommended pressure. (cid:127) Worn, old tires can cause accidents. If the tire’s tread is badly worn, or if your vehicle’s tires have been damaged, replace them. 385 Tire Sidewall Labeling Useful information about a tire is molded into its sidewall. The examples below show a typical passenger vehicle tire and a compact spare tire sidewall. Passenger (P-Metric) Tire Example 386 (A) Tire Size: The tire size is a combination of letters and numbers used to deﬁne a particular tire’s width, height, aspect ratio, construction type, and service description. See the “Tire Size” illustration later in this section for more detail.

See Loading Your Vehicle on page 307. Vehicle Maximum Load on the Tire: Load on an individual tire due to curb weight, accessory weight, occupant weight, and cargo weight. Vehicle Placard: A label permanently attached to a vehicle showing the vehicle’s capacity weight and the original equipment tire size and recommended inﬂation pressure. See “Tire and Loading Information Label” under Loading Your Vehicle on page 307. 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: (cid:127) Too much ﬂexing (cid:127) Too much heat 392 (cid:127) 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 A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar). 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 307. 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. Do not forget to check the compact spare tire, it should be at 60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire on page 418. 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 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. 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. Tire Pressure Monitor System Your vehicle has a Tire Pressure Monitor System (TPMS). This system uses radio and sensor technology to check tire pressure levels. The TPMS sensors are mounted onto each tire and wheel assembly, except for the spare tire. The TPMS sensors monitor the air pressure in your vehicle’s tires and transmit tire pressure readings to a receiver located in the vehicle. 393 The TPMS is designed to alert the driver, if a low tire pressure condition exists. If your vehicle has the Driver Information Center (DIC), the driver may also check tire pressure levels using the DIC buttons located on the instrument panel. When a low tire pressure condition is detected, the TPMS will illuminate the low tire pressure warning symbol, located on the instrument panel cluster, and at the same time a message to check the pressure in a speciﬁc tire will also appear on the DIC display. The low tire pressure warning symbol on the instrument panel cluster and the CHECK TIRE PRESSURE warning message on the DIC display 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 212 and DIC Warnings and Messages on page 221. You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the CHECK TIRE PRESSURE message will appear when the vehicle is ﬁrst started and the turn off as you start 394 to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inﬂated to the proper pressure. 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.) 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. 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. 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. 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 307, for an example of the tire information label and its location on your vehicle. Also see Inﬂation - Tire Pressure on page 392. 395 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 and Rotation on page 398 and Tires on page 385. Notice: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors. The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. If the system detects a missing or inoperable sensor, an error message SERVICE TIRE MONITOR SYSTEM will be shown on the DIC display. If you have replaced a tire/wheel assembly without transferring the TPMS sensors, the error message will be displayed. Once you re-install the TPMS sensors, the error message should go off. See your GM dealer for service if all TPMS sensors are installed and the error message comes on and stays on. Resetting the TPMS Sensor Identiﬁcation Codes 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’s side front tire, passenger’s side front tire, passenger’s side rear tire, and driver’s side rear tire using a TPMS diagnostic tool. See your GM dealer for service. The TPMS sensors may 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. You will have two minutes to match each tire and wheel position. If it takes longer than two minutes to match any tire and wheel position, or more than ﬁve minutes to match all four tire and wheel positions the matching process stops and you will need to start over. 396 The TPMS matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to RUN with the engine off. 3. Using the DIC, press the vehicle information button until the LEARN TIRE POSITIONS message displays. 4. Press the set/reset button to allow the system to learn the tire positions. The horn will sound twice to indicate the receiver is ready, and the TIRE LEARNING ACTIVE message will display. The TPMS system is ready for the sensor matching process to begin. 5. Start with the driver’s side front tire. 6. 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. To decrease the tire’s air-pressure use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. 7. Proceed to the passenger’s side front tire, and repeat the procedure in Step 6. 8. Proceed to the passenger’s side rear tire, and repeat the procedure in Step 6. 9. Proceed to the driver’s side rear tire, and repeat the procedure in Step 6. 10. After hearing the conﬁrming horn chirp for the driver’s side rear tire, the tire learning process ends. Turn the ignition switch to OFF. 11. Set all four tires to the recommended air pressure level as indicated on the tire and loading information label. 12. Put the valve caps back on the valve stems. The compact spare tire and wheel assembly does not have a TPMS sensor. If you replace one of the road tires with the compact spare tire, the SERVICE TIRE MONITOR SYSTEM message will be displayed on the DIC display screen. This message should go off once you re-install the road tire containing the TPMS sensor. 397 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 400 and Wheel Replacement on page 404 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 442 for scheduled rotation intervals.

Do not include the compact spare tire in your 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 392 and Loading Your Vehicle on page 307. Reset the Tire Pressure Monitor System. See “TPMS Sensor Identiﬁcation Codes” under Tire Pressure Monitor System on page 393. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Speciﬁcations on page 436. {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 408. 399 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. 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. (cid:127) The tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric. 400 (cid:127) The tire has a bump, bulge, or split. (cid:127) The tire has a puncture, cut, or other damage that cannot be repaired well because of the size or location of the damage. 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 an MS for mud and snow. See Tire Sidewall Labeling on page 386 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 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 418. {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. 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. 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 307, for more information about the Tire and Loading Information label and its location on your vehicle. 401 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 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. 402 See Buying New Tires on page 400 and Accessories and Modiﬁcations on page 325 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. 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. Warning: The temperature grade for this tire is established for a tire that is properly inﬂated and not overloaded. Excessive speed, under-inﬂation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. 403 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. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. 404 If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts, and wheel nuts for your vehicle. {CAUTION: Using the wrong replacement wheels, wheel bolts, or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement. Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 408 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 GM original equipment wheel. 405 Tire Chains {CAUTION: If your vehicle has P235/55R17, or P245/50R18 size tires, do not use tire chains. There is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. CAUTION: (Continued) 406 CAUTION: (Continued) 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 front tires. If your vehicle has P225/60R16 size Notice: tires, use tire chains only where legal and only when you must. Use only SAE Class S-type chains that are the proper size for your tires. Install them on the front tires and 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. 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. 407 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. 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 160 for more information. {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 PARK (P). 3. Turn off the engine and do not restart while the vehicle is raised. 4. Do not allow passengers to remain in the vehicle. CAUTION: (Continued) The following information will tell you next how to use the jack and change a tire. 408 Removing the Spare Tire and Tools The equipment you will need is located in the trunk. 1. If your vehicle has a center retainer, turn it counterclockwise to remove it. 2. Lift and remove the compact spare tire cover. 3. Remove the washer and retainer that holds down the jack and wheel wrench. 4. Remove the jack container with the jack and the wheel wrench. 5. Remove the spare tire from the vehicle. See Compact Spare Tire on page 418 for more information. 409 Removing the Flat Tire and Installing the Spare Tire The tools you will be using include the jack (A) and the wheel wrench (B). 1. Place the wheel wrench securely over the wheel nut. Turn the wheel wrench counterclockwise to loosen all the wheel nuts, but do no remove them yet. 410 2. Turn the jack handle clockwise to raise the jack lift head. {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. 3. Put the jack into the ﬂange in the frame which is located near each wheel well. The ﬂanges are accessible through openings in the plastic trim at the bottom of the vehicle. The front opening is about 8 inches (20 cm) back from the front wheel well. The rear opening is about 3 inches (8 cm) forward from the rear wheel well. 411 4. Position the jack and raise the jack head until it ﬁts ﬁrmly on the ridge in the vehicle’s frame nearest the ﬂat tire. Do not raise the vehicle yet. 5. Put the compact spare tire near the ﬂat tire. {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. 412 6. Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground for the compact spare tire to ﬁt under the vehicle. 7. Remove all wheel nuts and take off the ﬂat tire. {CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after time. The wheel could come off and cause an accident. When you change a wheel, CAUTION: (Continued) CAUTION: (Continued) remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. 8. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. 413 9. Install the compact spare tire. {CAUTION: Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident. 10. Put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub. 414 11. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely. {CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque speciﬁcation. See Capacities and Speciﬁcations on page 436 for wheel nut torque speciﬁcation. Improperly tightened wheel nuts can Notice: lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque speciﬁcation. See Capacities and Speciﬁcations on page 436 for the wheel nut torque speciﬁcation. 12. Tighten the wheel nuts ﬁrmly in a crisscross sequence as shown. Notice: Wheel covers will not ﬁt on your compact spare. If you try to put a wheel cover on the compact spare, you could damage the cover or the spare. Do not try to put the wheel cover on the compact spare tire. It will not ﬁt. Store the wheel cover in the trunk until you have the ﬂat tire repaired or replaced. 415 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. After you have put the compact spare tire on your vehicle, you need to store the ﬂat tire in your trunk. Store the ﬂat tire as far forward in the trunk as possible. To store the compact spare tire and tools, do the following: 416 A. Center Retainer B. Compact Spare Tire Cover C. Retainer D. Washer E. Jack Container F. Spare Tire G. Wheel Wrench H. Jack I. Foam Insert J. Bolt 1. Open the trunk. See Trunk on page 106 for more information. 2. Make sure the foam insert (I) is in place in the trunk compartment. 3. Reinstall the compact spare tire (F) making sure to line up the wheel center hole with the bolt (J). Then place it on the compartment ﬂoor. 4. Insert the jack container (E) into the spare tire (F). 5. Insert the wheel wrench (G) and jack (H) into the center of the compact spare tire making sure to line up the wheel nut hole with the bolt (I) on the compartment ﬂoor. 6. Secure the compact spare tire and the jack container (E) with the washer (D) and the retainer (C). 7. Reinstall the compact spare tire cover (B). 8. Secure with the center retainer (A). The compact spare tire is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See Compact Spare Tire on page 418 for more information. 417 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 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. 418 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 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: cleaning glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the integrated radio antenna and 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. If you use abrasive cleaners when Dust may be removed from small buttons and knobs using a small brush with soft bristles. Your dealer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your 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. 419 (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. 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: (cid:127) 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. (cid:127) 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. 420 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. 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. 421 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. Washing Your Vehicle The paint ﬁnish on the vehicle provides beauty, depth of color, gloss retention, and durability. 422 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. Approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 426. 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 422. Finish Care Occasional waxing or mild polishing of the vehicle by hand may be necessary to remove residue from the paint ﬁnish. Approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 426. 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. The 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. 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 the 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. To help keep the paint ﬁnish looking new, keep the vehicle in a garage or covered whenever possible. Windshield 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 glass cleaning liquid or powder and water solution. The windshield is clean if beads do not form when it is rinsed 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. 423 If you use strong soaps, chemicals, Aluminum or Chrome-Plated Wheels Your vehicle may have either 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: 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. The surface of these wheels is similar to the painted surface of your vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels. 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. 424 Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. 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. Do not take your 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. 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 dealer. Larger areas of ﬁnish damage can be corrected in your 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. 425 Vehicle Care/Appearance Materials Description Usage Description Polishing Cloth Wax-Treated Tar and Road Oil Remover Chrome Cleaner and Polish White Sidewall Tire Cleaner Vinyl Cleaner Glass Cleaner Chrome and Wire Wheel Cleaner Finish Enhancer Usage Swirl Remover Polish Interior and exterior polishing cloth.

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 your spare tire cover. 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 Do not remove this label from the vehicle. 427 Electrical System Add-On Electrical Equipment Notice: Do not add anything electrical to your vehicle unless you check with your dealer 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 86. Power Windows and Other Power Options Circuit breakers in the rear fuse block 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. 428 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. You will ﬁnd a fuse puller clipped in both of the fuse blocks. Snap the wide end of the fuse puller at the side indentations and pull the fuse out. The MaxiFuses are located in two fuse blocks, one located in the engine compartment on the passenger’s side and the other under the rear seat on the driver’s side. If a MaxiFuse should blow, have your vehicle serviced by your dealer immediately. Underhood Fuse Block The underhood fuse block is located on the passenger’s side of the engine compartment.
