All-Wheel Drive If your vehicle is equipped with all-wheel-drive, this is an additional system that needs lubrication. Transfer Case When to Check Lubricant It is not necessary to regularly check the transfer case fluid unless you suspect there is a leak or you hear an unusual noise. A fluid loss could indicate a problem. Have it inspected and repaired.


How to Check Lubricant


A. Drain Plug B. Fill Plug To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the filler plug hole, located on the transfer case, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. Use care not to overtighten the plug.


5-53


How to Check Lubricant


What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See Recommended Fluids and Lubricants on page 6-14. Rear Axle When to Check Lubricant It is not necessary to regularly check rear axle fluid unless you suspect there is a leak or you hear an unusual noise. A fluid loss could indicate a problem. Have it inspected and repaired.


To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the filler plug hole, located on the rear axle, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole.


5-54


What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See Recommended Fluids and Lubricants on page 6-14. Headlamp Aiming The vehicle has a visual optical headlamp aiming system. The aim has been preset at the factory and should need no further adjustment. However, if the vehicle is damaged in a crash, the headlamp aim may be affected and adjustment may be necessary. If oncoming vehicles flash their high beams at you, this may also mean the vertical aim needs to be adjusted. It is recommended that the vehicle is taken to your dealer/retailer for service if the headlamps need to be re-aimed. It is possible however, to re-aim the headlamps as described.


The vehicle should: (cid:129) Be placed so the headlamps are 25 ft. (7.6 m) from


a light colored wall.


(cid:129) Have all four tires on a level surface which is level


all the way to the wall.


(cid:129) Be placed so it is perpendicular to the wall. (cid:129) Not have any snow, ice, or mud on it. (cid:129) Be fully assembled and all other work stopped while


headlamp aiming is being performed.


(cid:129) Normally loaded with a full tank of fuel and one


person or 160 lbs (75 kg) sitting on the driver seat.


(cid:129) Have all tires properly inflated.


If your vehicle has a spare tire, ensure the spare tire is in its original location in the vehicle.


5-55


(cid:129) 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: 1. Open the hood. See Hood Release on page 5-13


for more information.

2. Locate the aim dot on the lens of the low-beam


headlamp.


3. Record the distance from the ground to the aim dot


on the low-beam headlamp.


4. At a 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) the width of the vehicle at the wall where it was marked 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 aimed. This should allow only the beam of light from the headlamp being aimed to be seen on the flat surface.


Driver Side Shown


7. Locate the vertical headlamp aiming screws, which are under the hood near each headlamp assembly. They are covered by a rubber caps. The adjustment screw can be turned with a 6 mm hex driver.


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. The top edge of the cut-off should be positioned at the bottom edge of the horizontal tape line.

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 vehicle Warranty booklet for details. For additional information refer to the tire manufacturer.


{ CAUTION:


(cid:129) Poorly maintained and improperly used


tires are dangerous.


(cid:129) Overloading your tires can cause


overheating as a result of too much flexing. You could have an air-out and a serious accident. See Loading the Vehicle on page 4-21.


CAUTION:


(Continued)


CAUTION:


(Continued)


(cid:129) Underinflated tires pose the same danger


as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. See Inflation - Tire Pressure on page 5-72.


(cid:129) 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:129) Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.


See High-Speed Operation on page 5-74 for inflation pressure adjustment for high speed driving.


5-63


If the vehicle has low-profile tires,


Low-Profile Performance Tires If your vehicle has 235/50ZR18, P235/50R18, 255/40ZR19 or 285/35ZR19 size tires, they are classified as low-profile tires. These tires are designed for very responsive driving on wet or dry pavement. You may also notice more road noise with low-profile performance tires and that they tend to wear faster. Notice: they are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like, potholes, or sharp edged objects, or when sliding into a curb. The vehicle warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and, when possible avoid contact with curbs, potholes, and other road hazards. Summer Performance Tires Many General Motors high performance models come factory-equipped with tires that are optimized for maximum dry and wet road performance while still retaining satisfactory tread life, excellent durability, and low noise levels. In severe winter climates where snowfall may be significant, these tires may be found to provide less traction.


5-64


Winter Tires If you expect to drive on snow or ice covered roads often, you may want to get winter tires for your vehicle. All season tires provide good overall performance on most surfaces but they may not offer the traction you would like or the same level of performance as winter tires on snow or ice covered roads. Winter tires, in general, are designed for increased traction on snow and ice covered roads. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After switching to winter tires, be alert for changes in vehicle handling and braking. See your dealer/retailer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires on page 5-82. If you choose to use winter tires: (cid:129) Use tires of the same brand and tread type on all


four wheel positions.


(cid:129) Use only radial ply tires of the same size, load range,


and speed rating as the original equipment tires.


Winter tires with the same speed rating as your original equipment tires may not be available for H, V, W, Y, and ZR speed rated tires. If you choose winter tires with a lower speed rating, never exceed the tire’s maximum speed capability.

5-71


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:129) Too much flexing (cid:129) Too much heat (cid:129) Tire overloading (cid:129) Premature or irregular wear (cid:129) Poor handling (cid:129) Reduced fuel economy


If your tires have too much air (over-inflation), you can get the following: (cid:129) Unusual wear (cid:129) Poor handling (cid:129) Rough ride (cid:129) Needless damage from road hazards A vehicle specific Tire and Loading Information label is attached to your vehicle. This label lists your vehicle’s original equipment tires and shows 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 the Vehicle on page 4-21. How you load your vehicle affects vehicle handling and ride comfort. Never load your vehicle with more weight than it was designed to carry.


5-72


When to Check Check your tires once a month or more. Do not forget to check the compact spare tire, if your 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 5-108. How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are underinflated. Check the tire’s inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km).


Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. 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.


5-73


High-Speed Operation


{ CAUTION:


Driving at high speeds, 100 mph (160 km/h) 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 235/50ZR18, 255/40ZR19 or 285/35ZR19 size tires, they will require inflation pressure adjustment when driving your vehicle at speeds of 100 mph (160 km/h) or higher. Set the cold inflation pressure to the maximum inflation pressure shown on the tire sidewall, or 44 psi (300 kPa), 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 Loading the Vehicle on page 4-21 and Inflation - Tire Pressure on page 5-72. 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 44 psi (300 kPa).


5-74


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.) 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 so on 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. See Tire Pressure Monitor Operation on page 5-76 for additional information.

Federal Communications Commission (FCC) and Industry and Science Canada The Tire Pressure Monitor System (TPMS) operates on a radio frequency and complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received,


including interference that may cause undesired operation.


Vehicles with TPMS operate on a radio frequency and comply with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference received,


including interference that may cause undesired operation of the device.


Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment.


Tire 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, if the vehicle has one. The TPMS sensors monitor the air pressure in the vehicle’s tires and transmits the tire pressure readings to a receiver located in the vehicle. Using the Driver Information Center (DIC), the driver can also check tire pressure levels using the DIC. For additional information and details about the DIC operation and displays see DIC Operation and Displays on page 3-50 and DIC Warnings and Messages on page 3-57.


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


5-76


A DIC warning message to check the pressure in a specific tire is also shown on the DIC display screen. The low tire pressure warning light and the DIC warning message come 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 could be an early indicator that the air pressure in the tire(s) are getting low and need to be inflated to the proper pressure. The 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 the tires when they are cold. See Loading the Vehicle on page 4-21, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inflation - Tire Pressure on page 5-72.


Your vehicle’s TPMS can warn you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation on page 5-80 and Tires on page 5-63. Notice: Using non-approved tire sealants could damage the Tire Pressure Monitor System (TPMS) sensors. TPMS sensor damage caused by using an incorrect tire sealant is not covered by the vehicle warranty. Always use the GM approved tire sealant available through your dealer/retailer. Factory-installed Tire Inflator Kits use a GM approved liquid tire sealant. Using non-approved tire sealants could damage the TPMS sensors. See Tire Sealant and Compressor Kit on page 5-90 for information regarding the inflator kit materials and instructions.


5-77


TPMS Malfunction Light and Message 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. A DIC warning message is also displayed. The low tire warning light and DIC warning message come on at each ignition cycle until the problem is corrected. Some of the conditions that can cause the malfunction light and DIC message to come on are: (cid:129) One of the road tires has been replaced with the


spare tire, if the vehicle has one. The spare tire does not have a TPMS sensor. The DIC message should go off once you re-install the road tire containing the TPMS sensor. The TPMS sensor matching process was not done or not completed successfully after rotating the vehicle’s tires. The DIC message should go off after successfully completing the sensor matching process. See “TPMS Sensor Matching Process” later in this section.


(cid:129) One or more TPMS sensors are missing or damaged. The DIC message and 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.


(cid:129) 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 5-82.


(cid:129) Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction.


If the TPMS is not functioning it cannot detect or signal a low tire condition. See your dealer/retailer for service if the TPMS malfunction light and DIC message comes on and stays on.


5-78


(cid:129) 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 your vehicle’s tires, the identification codes 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. If increasing the tire’s air 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 the first tire/wheel position, and five minutes overall, to match all four tire/wheel positions. If it takes longer than two minutes, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions, the matching process stops and you 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 the Remote Keyless Entry (RKE) transmitter’s


lock and unlock buttons at the same time for approximately five seconds. The horn sounds twice to signal the receiver is in relearn mode and Tire Learning Active message displays on the DIC screen.


4. Start with the driver side front tire. 5. Remove the valve cap from the valve stem. Activate


the TPMS sensor by increasing or decreasing the tire’s air pressure for 10 seconds, or until a horn chirp sounds. The horn chirp, which can take up to 30 seconds to sound, confirms that the TPMS sensor identification code has been matched to this tire position.


6. Proceed to the passenger side front tire, and repeat


the procedure in Step 5.


7. Proceed to the passenger side rear tire, and repeat


the procedure in Step 5.


8. Proceed to the driver side rear tire, and repeat the


procedure in Step 5.


9. After hearing the confirming horn chirp, for the driver side rear tire, the horn sounds two more times to signal the tire learning mode is no longer active. 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.


5-79


Tire Inspection and Rotation Inspect tires regularly for signs of wear or damage. Also inspect the spare tire, if the vehicle has one. For more information on tire inspection, see When It Is Time for New Tires on page 5-81. Tire rotation is not recommended if the vehicle has 255/40R19 size tires on the front wheels and 285/35R19 size tires on the rear wheels. Different tire sizes should not be rotated front to rear. Each tire and wheel should only be used in its original front or rear position. Tire rotation is recommended if the vehicle has the same size tires on all four wheel positions. These tires should be rotated every 5,000
to 8,000 miles (8 000 to 13 000 km). See Scheduled Maintenance on page 6-4. The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that your vehicle continues to perform most like it did when the tires were new.


5-80


Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-81
and Wheel Replacement on page 5-86.


Use the rotation pattern shown here when rotating tires of the same size installed on all four wheel positions. 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 5-72 and Loading the Vehicle on page 4-21.


Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation on page 5-76. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 5-133.


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.


{ CAUTION:


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


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.


5-81


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.


5-82


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 5-65, 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 5-80.


(cid:129) (cid:129) (cid:129) Winter tires with the same speed rating as your original equipment tires may not be available for H, V, W, Y and ZR speed rated tires. If you choose snow tires with a lower speed rating, never exceed the tire’s maximum speed capability.


{ CAUTION:


Mixing tires could cause you to lose control while driving. If you mix tires of different sizes (other than those originally installed on your vehicle), 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 (other than those originally installed on your vehicle), brands or types, may also cause damage to your vehicle. Be sure to use the correct size, brand, and type tires on all four wheels.


{ 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 it. 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 5-75. Your vehicle’s original equipment tires are listed on the Tire and Loading Information label. See Loading the Vehicle on page 4-21, for more information about the Tire and Loading Information label and its location on your vehicle.


5-83


Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this may affect the way your vehicle performs, including its braking, ride and handling characteristics, stability, and resistance to rollover. Additionally, if your vehicle has electronic systems such as, antilock brakes, traction control, and electronic stability control, the performance of these systems can be affected.


{ CAUTION:


If you add different sized wheels, your vehicle may not provide an acceptable level of performance and safety if tires not recommended for those wheels are selected. You may increase the chance that you will crash and suffer serious injury. Only use GM specific wheel and tire systems developed for your vehicle, and have them properly installed by a GM certified technician.


See Buying New Tires on page 5-82 and Accessories and Modifications on page 5-4 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.


5-84


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.


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.


5-85


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. CTS-V models should only use adhesive wheel weights to balance the tires and wheels.


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.


5-86


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 clearance to the body and chassis.


{ CAUTION:


{ CAUTION:


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


{ CAUTION:


Never use oil or grease on studs or the threads of the wheel nuts. If you do, the wheel nuts might come loose and the wheel could fall off, causing a crash.


Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to a crash. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts.


Improperly tightened wheel nuts can lead


Notice: to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification.


5-87


Used Replacement Wheels


Tire Chains


{ CAUTION:


{ CAUTION:


Putting a used wheel on the 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.


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, re-adjust or remove the device if it is contacting the vehicle, and do not spin the wheels. If you do find traction devices that will fit, install them on the rear tires.


5-88


If a Tire Goes Flat It is unusual for a tire to blow out while you are driving, especially if you maintain the tires properly. See Tires on page 5-63. If air goes out of a tire, it is much more likely to leak out slowly. But, if you should ever have a blow out, 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 blow out, particularly on a curve, acts much like a skid and may require the same correction you would use in a skid. In any rear blow out, 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. If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place and stopping. 1. Turn on the hazard warning flashers. See Hazard


Warning Flashers on page 3-6.


2. Park your vehicle. If your vehicle has an automatic transmission, set the parking brake firmly and put the shift lever in P (Park). If your vehicle has a manual transmission, move the shift lever to R (Reverse) and set the parking brake firmly.


3. Turn off the engine. 4. Inspect the flat tire.


{ CAUTION:


Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. If a jack is provided with the vehicle, it 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. If a jack is provided with the vehicle, only use it for changing a flat tire.


This vehicle may come with a jack and spare tire or a tire sealant and compressor kit. To use the jack and spare tire, see Changing a Flat Tire on page 5-100. To use the tire sealant and compressor kit, see Tire Sealant and Compressor Kit on page 5-90.


5-89


Tire Sealant and Compressor Kit


{ CAUTION:


Idling a vehicle in an enclosed area with poor ventilation is dangerous. Engine exhaust may enter the vehicle. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. Never run the engine in an enclosed area that has no fresh air ventilation. For more information, see Engine Exhaust on page 2-51.


{ CAUTION:


Over-inflating a tire could cause the tire to rupture and you or others could be injured. Be sure to read and follow the tire sealant and compressor kit instructions and inflate the tire to its recommended pressure. Do not exceed the recommended pressure.


5-90


{ CAUTION:


Storing the tire sealant and compressor kit 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 the tire sealant and compressor kit in its original location.


If this vehicle has a tire sealant and compressor kit, there may not be a spare tire, tire changing equipment, and on some vehicles there may not be a place to store a tire. The tire sealant and compressor can be used to temporarily seal punctures up to 1⁄4 inch (6 mm) in the tread area of the tire. It can also be used to inflate an under inflated tire. If the tire has been separated from the wheel, has damaged sidewalls, or has a large puncture, the tire is too severely damaged for the tire sealant and compressor kit to be effective. See Roadside Service on page 7-8. Read and follow all of the tire sealant and compressor kit instructions.


This vehicle may have one of the following tire sealant and compressor kits. The kit includes:


A. Selector Switch (Sealant/Air or Air Only)


B. On/Off Button C. Pressure Gage D. Pressure Deflation


Button (If equipped)


E. Tire Sealant Canister


Sealant/Air Hose (Clear)


F. Air Only Hose


(Black)


G. Power Plug


5-91


Tire Sealant Read and follow the safe handling instructions on the label adhered to the sealant canister. Check the tire sealant expiration date on the sealant canister. The sealant canister should be replaced before its expiration date. Replacement sealant canisters are available at your local dealer/retailer. See “Removal and Installation of the Sealant Canister” following. There is only enough sealant to seal one tire. After usage, the sealant canister and sealant/air hose assembly must be replaced. See “Removal and Installation of the Sealant Canister” following.


Using the Tire Sealant and Compressor Kit to Temporarily Seal and Inflate a Punctured Tire Follow the directions closely for correct sealant usage.

using the air compressor.


8. Turn the selector switch (A) counterclockwise to the


Sealant + Air position.


5-93


When using the tire sealant and compressor kit during cold temperatures, warm the kit in a heated environment for 5 minutes. This will help to inflate the tire faster. Always do a safety check first. See If a Tire Goes Flat on page 5-89. Do not remove any objects that have penetrated the tire. 1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and Compressor Kit Storage on page 5-98.


2. Unwrap the sealant/air hose (F) and the power


plug (H).


If the recommended pressure cannot be


Notice: reached after approximately 25 minutes, the vehicle should not be driven farther. The tire is too severely damaged and the tire sealant and compressor kit cannot inflate the tire. Remove the power plug from the accessory power outlet and unscrew the inflating hose from the tire valve. See Roadside Service on page 7-8. 11. Press the on/off button (B) to turn the tire sealant


and compressor kit off. The tire is not sealed and will continue to leak air until the vehicle is driven and the sealant is distributed in the tire, therefore, Steps 12 through 18 must be done immediately after Step 11. Be careful while handling the tire sealant and compressor kit as it could be warm after usage. 12. Unplug the power plug (H) from the accessory


power outlet in the vehicle.


13. Turn the sealant/air hose (F) counterclockwise to


remove it from the tire valve stem.


9. Press the on/off (B) button to turn the tire sealant


and compressor kit on. The compressor will inject sealant and air into the tire. The pressure gage (C) will initially show a high pressure while the compressor pushes the sealant into the tire. Once the sealant is completely dispersed into the tire, the pressure will quickly drop and start to rise again as the tire inflates with air only. 10. Inflate the tire to the recommended inflation pressure


using the pressure gage (C). The recommended inflation pressure can be found on the Tire and Loading Information label. See Inflation - Tire Pressure on page 5-72. The pressure gage (C) may read higher than the actual tire pressure while the compressor is on. Turn the compressor off to get an accurate pressure reading. The compressor may be turned on/off until the correct pressure is reached.

14. Replace the tire valve stem cap. 15. Replace the sealant/air hose (F), and the power


plug (H) back in their original location.


16. If the flat tire was


able to inflate to the recommended inflation pressure, remove the maximum speed label from the sealant canister (E) and place it in a highly visible location.


19. Stop at a safe location and check the tire pressure. Refer to Steps 1 through 11 under “Using the Tire Sealant and Compressor Kit without Sealant to Inflate a Tire (Not Punctured).” If the tire pressure has fallen more than 10 psi (68 kPa) below the recommended inflation pressure, stop driving the vehicle. The tire is too severely damaged and the tire sealant cannot seal the tire. See Roadside Service on page 7-8. If the tire pressure has not dropped more than 10 psi (68 kPa) from the recommended inflation pressure, inflate the tire to the recommended inflation pressure.


20. Wipe off any sealant from the wheel, tire, and


vehicle.


The label is a reminder not to exceed 55 mph (90 km/h) until the damaged tire is repaired or replaced.


21. Dispose of the used sealant canister (E) and sealant/


air hose (F) assembly at a local dealer/retailer or in accordance with local state codes and practices.

Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on the hazard warning flashers. See Hazard Warning Flashers on page 3-6.


{ 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.


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.

Removing the Flat Tire and Installing the Spare Tire 1. Do a safety check before proceeding. See Changing


a Flat Tire on page 5-100 for more information.


2. Loosen the wheel nuts, but do not remove them yet,


using the wheel wrench. Turn the handle about 180 degrees, then return the handle back to the starting position. This avoids taking the wrench off the lug nut for each turn.

3. Find the jacking location using the diagram above


and corresponding V-shaped locating notches located in the plastic molding.


4. Insert the hooked end of the extension handle


through the jack and the flat end through the wheel wrench.


{ 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:


Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. If a jack is provided with the vehicle, it 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. If a jack is provided with the vehicle, only use it for changing a flat tire.

{ 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.


If you position the jack under the rocker


Notice: molding and attempt to raise the vehicle, you could break the molding and/or cause other damage to your vehicle. Always position the jack so that when the jack head is raised, it will fit firmly in the notch located inboard from the rocker molding. 5. Turn the wheel wrench counterclockwise to lower


the jack lift head until the jack fits under the vehicle.

6. Raise the jack by turning the wheel wrench


clockwise until the slots in the jack head fit into the metal flange located behind the V–shaped locating notches on the plastic molding as shown.


7. Put the compact spare tire near you. 8. Raise the vehicle by turning the wheel wrench clockwise. Raise the vehicle far enough off the ground for the compact spare tire to fit under the vehicle.


9. Remove all the wheel nuts and the flat tire.


{ CAUTION:


{ 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 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 Changing a Flat Tire on page 5-100.


Never use oil or grease on bolts or nuts because the nuts might come loose. The vehicle’s wheel could fall off, causing a crash.


10. Remove any rust or dirt


from the wheel bolts, mounting surfaces, and spare wheel.


11. Install the spare tire. 12. Put the wheel nuts back on with the rounded end of


the nuts toward the wheel.

13. Tighten each wheel nut by turning it clockwise with


your hand until the wheel is held against the hub.


14. Lower the vehicle by turning the wheel wrench


counterclockwise. Lower the jack completely.


{ CAUTION:


Wheel nuts that are improperly or incorrectly tightened can cause the wheels to become loose or come off. The wheel nuts should be tightened with a torque wrench to the proper torque specification after replacing. Follow the torque specification supplied by the aftermarket manufacturer when using accessory locking wheel nuts. See Capacities and Specifications on page 5-133 for original equipment wheel nut torque specifications.


15. Tighten the wheel nuts


firmly in a crisscross sequence as shown.

Compact Spare Tire and Tools Use the following diagram as a guide for storing the compact spare tire and tools in the trunk:


Compact Spare Tire


{ CAUTION:


Driving with more than one compact spare tire at a time could result in loss of braking and handling. This could lead to a crash and you or others could be injured. Use only one compact spare tire at a time.


If your vehicle is equipped with a compact spare tire it 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 the vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails which can damage the tire, wheel and other parts of the 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 the compact spare. Using them can damage the vehicle and can damage the chains too. Do not use tire chains on the compact spare.


Appearance Care


Interior Cleaning The vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on the upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from the upholstery. It is important to keep the upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible. The 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 home furnishings may also transfer color to the vehicle’s interior.


5-109


When cleaning the 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: Using abrasive cleaners when cleaning glass surfaces on the vehicle, could scratch the glass and/or cause damage to the rear window defogger. When cleaning the glass on the vehicle, use only a soft cloth and glass cleaner. Many cleaners contain solvents that may become concentrated in the vehicle’s breathing space. Before using cleaners, read and adhere to all safety instructions on the label. While cleaning the vehicle’s interior, maintain adequate ventilation by opening the vehicle’s doors and windows. Dust may be removed from small buttons and knobs using a small brush with soft bristles.


Products that remove odors from the vehicle’s upholstery and clean the vehicle’s glass can be obtained from your dealer/retailer. Do not clean the 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 the vehicle’s


interior surfaces.


(cid:129) Heavy pressure or aggressive rubbing with a


cleaning cloth. Use of heavy pressure can damage the 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 the vehicle’s interior.


5-110


(cid:129) (cid:129) 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.


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.


5-111


(cid:129) (cid:129) Leather A soft cloth dampened with water can 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 the leather and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean the vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Never use shoe polish on 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 the interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean the 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 the 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.


5-112


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


Speaker Covers Vacuum around a speaker cover gently, so that the speaker will not be damaged. Clean spots with just water and mild soap.


Care of Safety Belts Keep belts clean and dry.
