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 5-62. (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 the tire’s tread is badly worn, or if your vehicle’s tires have been damaged, replace them. Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about the tire warranty and where to obtain service, see the vehicle warranty booklet for details. For additional information refer to the tire manufacturer. { CAUTION: Poorly maintained and improperly used tires are dangerous. (cid:129) Overloading your vehicle’s 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 4-26. CAUTION: (Continued) 5-54 Low-Proﬁle Performance Tire If the vehicle has 225/40R18 size tires, they are classiﬁed as low-proﬁle performance 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. The 225/40R18 tire is a high performance tire designed for dry traction and handling performance which may result in reduced tread life of 15,000 miles (24 140 km) or less depending on individual driving behavior. 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. If the vehicle has low-proﬁle tires, Winter Tires If the vehicle has 225/40R18 size tires, they are classiﬁed as performance tires. These tires are designed for very responsive driving on wet or dry pavement. If you expect to drive on snow or ice covered roads often, you may want to get winter tires for the 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 5-72. 5-55 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. 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. 5-56 Passenger (P-Metric) Tire Example (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. (B) TPC Spec (Tire Performance Criteria Speciﬁcation): Original equipment tires designed to GM’s speciﬁc tire performance criteria have a TPC speciﬁcation code molded onto the sidewall. GM’s TPC speciﬁcations meet or exceed all federal safety guidelines. If your vehicle has 205/55R16 size tires, they meet the GM TPC Spec rating, but the TPC Spec code has not been molded onto the tire’s sidewall. (C) DOT (Department of Transportation): The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S. Department of Transportation Motor Vehicle Safety Standards. (D) Tire Identiﬁcation Number (TIN): The letters and numbers following DOT (Department of Transportation) code is the Tire Identiﬁcation Number (TIN).

(D) Maximum Cold Inﬂation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load. (E) Tire Inﬂation: The temporary use tire or compact spare tire should be inﬂated to 60 psi (420 kPa). For more information on tire pressure and inﬂation see Inﬂation - Tire Pressure on page 5-62. (F) Tire Size : A combination of letters and numbers deﬁne a tire’s width, height, aspect ratio, construction type and service description. The letter T as the ﬁrst character in the tire size means the tire is for temporary use only. Compact Spare Tire Example (A) Temporary Use Only: The compact spare tire or temporary use tire has a tread life of approximately 3,000 miles (5 000 km) and should not be driven at speeds over 65 mph (105 km/h). The compact spare tire is for emergency use when a regular road tire has lost air and gone ﬂat. If your vehicle has a compact spare tire, see Compact Spare Tire on page 5-109 and If a Tire Goes Flat on page 5-79. 5-58 (G) TPC Spec (Tire Performance Criteria Speciﬁcation): Original equipment tires designed to GM’s speciﬁc tire performance criteria have a TPC speciﬁcation code molded onto the sidewall. GM’s TPC speciﬁcations meet or exceed all federal safety guidelines. Tire Size The following illustration shows an example of a typical passenger vehicle tire size. (A) Passenger (P-Metric) Tire: The United States version of a metric tire sizing system. The letter P as the ﬁrst character in the tire size means a passenger vehicle tire engineered to standards set by the U.S. Tire and Rim Association. A tire size without the letter P as the ﬁrst character is certiﬁed to European standards. (B) Tire Width: The three-digit number indicates the tire section width in millimeters from sidewall to sidewall. (C) Aspect Ratio: A two-digit number that indicates the tire height-to-width measurements. For example, if the tire size aspect ratio is 60, as shown in item C of the illustration, it would mean that the tire’s sidewall is 60 percent as high as it is wide. (D) Construction Code: A letter code is used to indicate the type of ply construction in the tire. The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted-bias ply construction. (E) Rim Diameter: Diameter of the wheel in inches. (F) Service Description: These characters represent the load index and speed rating of the tire. The load index represents the load carry capacity a tire is certiﬁed to carry. The speed rating is the maximum speed a tire is certiﬁed to carry a load. 5-59 Tire Terminology and Deﬁnitions Air Pressure: The amount of air inside the tire pressing outward on each square inch of the tire.

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 the Vehicle on page 4-26. 5-62 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 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 the Vehicle on page 4-26. 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, if the vehicle has one. It should be at 60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire on page 5-109. 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. 5-63 Tire Pressure Monitor System The vehicle may have a Tire Pressure Monitor System (TPMS). This system 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 soon as possible, and inﬂate them to the proper pressure. Driving on a signiﬁcantly under-inﬂated tire causes the tire to overheat and can lead to tire failure. Under-inﬂation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. 5-64 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 5-65 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. If your vehicle has this feature, 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 transmit the tire pressure readings to a receiver located in the vehicle. When a low tire pressure condition is detected, the TPMS turns on the low tire pressure warning light located on the instrument panel cluster. At the same time a message to check the pressure in a speciﬁc tire appears on the Driver Information Center (DIC) display. The low tire pressure warning light and the DIC warning message come on at each ignition cycle until the tires are inﬂated to the correct inﬂation pressure. Using the DIC, tire pressure levels can be viewed by the driver. For additional information and details about the DIC operation and displays see DIC Operation and Displays on page 3-44 and DIC Warnings and Messages on page 3-46. 5-65 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. A Tire and Loading Information label 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 the Vehicle on page 4-26, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inﬂation - Tire Pressure on page 5-62. 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 5-70 and Tires on page 5-54. 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 5-80 for information regarding the inﬂator kit materials and instructions. 5-66 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 TPMS malfunction light and DIC message should go off once you re-install the road tire containing the TPMS sensor. The TPMS sensor matching process was started but not completed or not completed successfully after rotating the vehicle’s tires. The DIC message and TPMS malfunction light should go off once the TPMS sensor matching process is performed successfully. See “TPMS Sensor Matching Process” later in this section. (cid:129) (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 5-72. (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. TPMS Sensor Matching Process Each TPMS sensor has a unique identiﬁcation code. Any time you replace one or more of the TPMS sensors or rotate the vehicle’s tires, the identiﬁcation codes need to be matched to the new tire/wheel location. The sensors are matched, to the tire/wheel locations, in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service. The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire’s air pressure. When increasing the tire’s pressure, do not exceed the maximum inﬂation pressure indicated on the tire’s sidewall. To decrease the tire’s air-pressure use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. You have two minutes to match each tire and wheel position. If it takes longer than two minutes to match any tire and wheel position, the matching process stops and you need to start over. 5-67 7.

Activate the TPMS sensor by increasing or decreasing the tire’s air pressure for about eight seconds. The horn chirp, can take up to 30 seconds to sound. It chirps one time and then all the turn signals ﬂash one time to conﬁrm the sensor identiﬁcation code has been matched to the tire/wheel position. 7. The passenger side front turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the passenger side front tire and repeat the procedure in Step 6. 8. The passenger side rear turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the passenger side rear tire and repeat the procedure in Step 6. 9. The driver side rear turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the driver side rear tire, and repeat the procedure in Step 6. 10. After hearing the single horn chirp for the driver side rear tire, two additional horn chirps sound to indicate the tire learning process is done. The LEARN COMPLETE message displays if all four tire positions are learned. Turn the ignition switch to LOCK/OFF. If no tires are learned after entering the TPMS learn mode, or if communication with the receiver stops, or if the time limit has expired, the TIRE LEARN? message displays on the DIC. Turn the ignition switch to LOCK/OFF and start over beginning with Step 2. 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. 5-69 Tire Inspection and Rotation We recommend that you regularly inspect the vehicle’s tires, including the spare tire, if the vehicle has one, for signs of wear or damage. See When It Is Time for New Tires on page 5-71 for more information. Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). See Scheduled Maintenance on page 6-4. If this vehicle has P225/40R18 size tires, they should be rotated every 3,000 miles (5 000 km). The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that the vehicle continues to perform most like it did when the tires were new. Any time you notice unusual wear, rotate the tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-71 and Wheel Replacement on page 5-76. 5-70 When rotating the vehicle’s tires, always use the correct rotation pattern shown here. Do not include the compact spare tire, if the vehicle has one, in the tire rotation. After the tires have been rotated, adjust the front and rear inﬂation pressures as shown on the Tire and Loading Information label. See Inﬂation - Tire Pressure on page 5-62 and Loading the Vehicle on page 4-26. If the vehicle has the Tire Pressure Monitor System (TPMS), reset the TPMS sensors after rotating the tires. See Tire Pressure Monitor Operation on page 5-65. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Speciﬁcations on page 5-124. { CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire on page 5-88. When It Is Time for New Tires Various factors, such as maintenance, temperatures, driving speeds, vehicle loading, and road conditions inﬂuence when you need new tires. One way to tell when it is time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. You need new tires if any of the following statements are true: (cid:129) You can see the indicators at three or more places around the tire. (cid:129) You can see cord or fabric showing through the tire’s rubber. 5-71 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. 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 5-56 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 5-70 for information on proper tire rotation. 5-72 (cid:129) (cid:129) (cid:129) If you must replace your vehicle’s tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias-belted tires) as your vehicle’s original tires. Vehicles that have a tire pressure monitoring system could give an inaccurate low-pressure warning if non-TPC Spec rated tires are installed on your vehicle. Non-TPC Spec rated tires may give a low-pressure warning that is higher or lower than the proper warning level you would get with TPC Spec rated tires. See Tire Pressure Monitor System on page 5-64. Your vehicle’s original equipment tires are listed on the Tire and Loading Information Label. See Loading the Vehicle on page 4-26, for more information about the Tire and Loading Information Label and its location on your vehicle. { CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes, brands, or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes, brands, or types may also cause damage to your vehicle. Be sure to use the correct size, brand, and type of tires on all wheels. It is all right to drive with your compact spare temporarily, as it was developed for use on your vehicle. See Compact Spare Tire on page 5-109. { 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. 5-73 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 5-72 and Accessories and Modiﬁcations on page 5-3 for additional information. Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traffic Safety Administration (NHTSA), which grades tires by treadwear, traction, and temperature performance. This applies only to vehicles sold in the United States. The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading (UTQG) system does not apply to deep tread, winter-type snow tires, space-saver, or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards. 5-74 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. 5-75 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. Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer/retailer if any of these conditions exist. Your dealer/retailer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts, wheel nuts, or Tire Pressure Monitor System (TPMS) sensors, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts, wheel nuts, and TPMS sensors for your vehicle. 5-76 Used Replacement Wheels { 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. { CAUTION: Using the wrong replacement wheels, wheel bolts, or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement. Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-88 for more information. 5-77 Tire Chains { CAUTION: If your vehicle has P195/65R15, P205/55R16, P205/50R17, or 225/40R18 size tires, do not use tire chains. They can damage your vehicle because there is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination, and road conditions. Follow that manufacturer’s instructions. CAUTION: (Continued) CAUTION: (Continued) 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 a tire size other than Notice: P195/65R15, P205/55R16, P205/50R17 or 225/40R18 size 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. 5-78 If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain the tires properly. See Tires on page 5-54. 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. 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 the vehicle. Set the parking brake ﬁrmly and put the shift lever in P (Park). 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 5-88. To use the tire sealant and compressor kit, see Tire Sealant and Compressor Kit on page 5-80. 5-79 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 2-35. { 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. 5-80 { 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 Assistance Program on page 7-8. Read and follow all of the tire sealant and compressor kit instructions. The kit includes: 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. A. Air Compressor B. Tire Sealant Canister C. Power Plug D. On/Off Button E. Pressure Gage F. Air Only Hose (Black) G. Sealant/Air Hose (Clear) 5-81 Using the Tire Sealant and Compressor Kit to Temporarily Seal and Inﬂate a Punctured Tire 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. 5-82 Always do a safety check ﬁrst. See If a Tire Goes Flat on page 5-79. 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 5-88. Make sure the on/off button (D) is in the off (O) position. 2. Unwrap the sealant/air hose (F) and the power plug (C). 3. Place the kit on the ground. Make sure the tire valve stem is positioned close to the ground so the hose will reach it. 4. Remove the valve stem cap from the ﬂat tire by turning it counterclockwise. 5. Attach the sealant/air hose (F) onto the tire valve stem. Turn it clockwise until it is tight. 6. Plug the power plug (C) into the accessory power outlet in the vehicle. Unplug all items from other accessory power outlets. See Accessory Power Outlet(s) on page 3-16. If the vehicle has an accessory power outlet, do not use the cigarette lighter. If the vehicle only has a cigarette lighter, use the cigarette lighter. Do not pinch the power plug cord in the door or window. 7. Start the vehicle. The vehicle must be running while using the air compressor. 8. Press the on/off (D) button to turn the tire sealant and compressor kit on. The compressor will inject sealant and air into the tire. The pressure gage (E) 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. 9. Inﬂate the tire to the recommended inﬂation pressure using the pressure gage (E). The recommended inﬂation pressure can be found on the Tire and Loading Information label. See Inﬂation - Tire Pressure on page 5-62. The pressure gage (E) 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. 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 Assistance Program on page 7-8. 10. Press the on/off button (D) 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 11 through 17 must be done immediately after Step 10. Be careful while handling the tire sealant and compressor kit as it could be warm after usage. 11. Unplug the power plug (C) from the accessory power outlet in the vehicle. 12. Turn the sealant/air hose (F) counterclockwise to remove it from the tire valve stem. 5-83 13. Replace the tire valve stem cap. 14. Replace the sealant/air hose (F), and the power plug (C) back in their original location. 15. If the ﬂat tire was able to inﬂate to the recommended inﬂation pressure, remove the maximum speed label from the sealant canister (B) and place it in a highly visible location. The label is a reminder not to exceed 55 mph (90 km/h) until the damaged tire is repaired or replaced. 16. Return the equipment to its original storage location in the vehicle. 17. Immediately drive the vehicle 5 miles (8 km) to distribute the sealant in the tire. 18. 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 Assistance Program 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. 19. Wipe off any sealant from the wheel, tire or vehicle. 20. Dispose of the used sealant canister (B) and sealant/air hose (F) assembly at a local dealer/retailer or in accordance with local state codes and practices. 21. Replace it with a new canister available from your dealer/retailer. 22. After temporarily sealing a tire using the tire sealant and compressor kit, take the vehicle to an authorized dealer/retailer within a 100 miles (161 km) of driving to have the tire repaired or replaced. 5-84 Using the Tire Sealant and Compressor Kit without Sealant to Inﬂate a Tire (Not Punctured) To use the air compressor to inﬂate a tire with air only and not sealant: Always do a safety check ﬁrst. See If a Tire Goes Flat on page 5-79. 1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and Compressor Kit Storage on page 5-88. 2.

Notice: Make sure that the jack lift head is in the correct position or you may damage your vehicle. The repairs would not be covered by your warranty. 2. If your vehicle has plastic wheel covers, use the wheel wrench to loosen the plastic wheel nut caps. Once the plastic wheel nut caps have been loosened with the wheel wrench, you can ﬁnish loosening them with your ﬁngers. The plastic nut caps do not come off. 5-94 { CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. { CAUTION: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to ﬁt the jack lift head into the proper location before raising the vehicle. 8. Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to ﬁt under the vehicle. 5-95 5. Position the jack lift head at the jack location nearest the ﬂat tire. The front location is about 8 inches (20 cm) behind the front wheel opening. The rear location is about 4 inches (10 cm) in front of the rear wheel opening. 6. Raise the jack head until it ﬁts ﬁrmly in the vehicle’s frame, where the notch is located, nearest the ﬂat tire. 7. Put the compact spare tire near the ﬂat tire. 9. Remove all of the wheel nuts and ﬂat tire. 10. Remove any rust or dirt from the wheel bolts, mounting surfaces, and spare wheel. { 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 5-88. 5-96 11.
