Incorrect Installation 5-61 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 4-23. CAUTION: (Continued) 5-62 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 5-71. (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 5-72 for inﬂation pressure adjustment for high speed driving. If the vehicle has low-proﬁle tires, they Low-Proﬁle Performance Tire The original equipment tires on your vehicle 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 tires and that they tend to wear faster. Notice: 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. 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 5-78. 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. 5-63 Tire Sidewall Labeling Useful information about a tire is molded into its sidewall. The example below shows a typical passenger (p-metric) tire sidewall. 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. 5-64 (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. (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 code are the Tire Identiﬁcation Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture. (E) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread. (F) Uniform Tire Quality Grading (UTQG): Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resistance. For more information see Uniform Tire Quality Grading on page 5-80. (G) Maximum Cold Inﬂation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load. Tire Size The following illustration shows an example of a typical passenger (p-metric) 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. (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. 5-65 Tire Terminology and Deﬁnitions Air Pressure: The amount of air inside the tire pressing outward on each square inch of the tire. Air pressure is expressed in pounds per square inch (psi) or kilopascal (kPa). Accessory Weight: This means the combined weight of optional accessories. Some examples of optional accessories are, automatic transmission, power steering, power brakes, power windows, power seats, and air conditioning. Aspect Ratio: The relationship of a tire’s height to its width. Belt: A rubber coated layer of cords that is located between the plies and the tread. Cords may be made from steel or other reinforcing materials. Bead: The tire bead contains steel wires wrapped by steel cords that hold the tire onto the rim. Bias Ply Tire: A pneumatic tire in which the plies are laid at alternate angles less than 90 degrees to the centerline of the tread. Cold Tire Pressure: The amount of air pressure in a tire, measured in pounds per square inch (psi) or kilopascals (kPa) before a tire has built up heat from driving. See Inﬂation - Tire Pressure on page 5-71. Curb Weight: The weight of a motor vehicle with standard and optional equipment including the maximum capacity of fuel, oil, and coolant, but without passengers and cargo. DOT Markings: A code molded into the sidewall of a tire signifying that the tire is in compliance with the U.S. Department of Transportation (DOT) motor vehicle safety standards. The DOT code includes the Tire Identiﬁcation Number (TIN), an alphanumeric designator which can also identify the tire manufacturer, production plant, brand, and date of production. GVWR: Gross Vehicle Weight Rating. See Loading the Vehicle on page 4-23. GAWR FRT: Gross Axle Weight Rating for the front axle. See Loading the Vehicle on page 4-23. 5-66 GAWR RR: Gross Axle Weight Rating for the rear axle. See Loading the Vehicle on page 4-23. Intended Outboard Sidewall: The side of an asymmetrical tire, that must always face outward when mounted on a vehicle. Kilopascal (kPa): The metric unit for air pressure. Light Truck (LT-Metric) Tire: A tire used on light duty trucks and some multipurpose passenger vehicles.

The maximum air pressure is molded onto the sidewall. Maximum Load Rating: The load rating for a tire at the maximum permissible inﬂation pressure for that tire. Maximum Loaded Vehicle Weight: The sum of curb weight, accessory weight, vehicle capacity weight, and production options weight. Normal Occupant Weight: The number of occupants a vehicle is designed to seat multiplied by 150 lbs (68 kg). See Loading the Vehicle on page 4-23. Occupant Distribution: Designated seating positions. Outward Facing Sidewall: The side of an asymmetrical tire that has a particular side that faces outward when mounted on a vehicle. The side of the tire that contains a whitewall, bears white lettering, or bears manufacturer, brand, and/or model name molding that is higher or deeper than the same moldings on the other sidewall of the tire. Passenger (P-Metric) Tire: A tire used on passenger cars and some light duty trucks and multipurpose vehicles. Recommended Inﬂation Pressure: Vehicle manufacturer’s recommended tire inﬂation pressure as shown on the tire placard. See Inﬂation - Tire Pressure on page 5-71 and Loading the Vehicle on page 4-23. 5-67 Radial Ply Tire: A pneumatic tire in which the ply cords that extend to the beads are laid at 90 degrees to the centerline of the tread. Rim: A metal support for a tire and upon which the tire beads are seated. Sidewall: The portion of a tire between the tread and the bead. Speed Rating: An alphanumeric code assigned to a tire indicating the maximum speed at which a tire can operate. Traction: The friction between the tire and the road surface. The amount of grip provided. Tread: The portion of a tire that comes into contact with the road. Treadwear Indicators: Narrow bands, sometimes called wear bars, that show across the tread of a tire when only 1/16 inch (1.6 mm) of tread remains. See When It Is Time for New Tires on page 5-77. UTQGS (Uniform Tire Quality Grading Standards): A tire information system that provides consumers with ratings for a tire’s traction, temperature, and treadwear. Ratings are determined by tire manufacturers using government testing procedures. The ratings are molded into the sidewall of the tire. See Uniform Tire Quality Grading on page 5-80. Vehicle Capacity Weight: The number of designated seating positions multiplied by 150 lbs (68 kg) plus the rated cargo load. See Loading the Vehicle on page 4-23. Vehicle Maximum Load on the Tire: Load on an individual tire due to curb weight, accessory weight, occupant weight, and cargo weight. Vehicle Placard: A label permanently attached to a vehicle showing the vehicle’s capacity weight and the original equipment tire size and recommended inﬂation pressure. See “Tire and Loading Information Label” under Loading the Vehicle on page 4-23. 5-68 Run-Flat Tires This vehicle, when new, had run-ﬂat tires. There is no spare tire, no tire changing equipment, and no place to store a tire in the vehicle. Run-ﬂat tires perform so well without any air that a Tire Pressure Monitor System (TPMS) is used to alert you if a tire has lost pressure. { CAUTION: When the low tire warning light is displayed on the instrument panel cluster, your vehicle’s handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Do not drive over 55 mph (90 km/h) when the low tire warning light is displayed. Drive cautiously and check your tire pressures as soon as you can. If a tire goes ﬂat, you will not need to stop on the side of the road to change the tire. You can just keep on driving. The shorter the distance you drive and the slower the speed, the greater the chance that the tire will not have to be replaced. If you drive on a deﬂated run-ﬂat tire for 25 miles (40 km) or less and at speeds of 55 mph (90 km/h) or less, there is a good chance that the tire can be repaired. The tires on coupe, convertible and Z06 models can operate effectively with no air pressure for up to 100 miles (160 km) at speeds up to 55 mph (90 km/h), but the tire would then have to be replaced. The tires on ZR1 models can operate effectively with no air pressure for up to 50 miles (80 km) at speeds up to 55 mph (90 km/h), but the tire would then have to be replaced. When a tire is ﬁlled with air, it provides a cushion between the road and the wheel. Because you will not have this cushion when driving on a deﬂated tire, try to avoid potholes that could damage your wheel and require replacement of it. 5-69 Some road hazards can damage a tire beyond repair. This damage could occur even before you have driven on the tire in a deﬂated condition. When a tire has been damaged, or if you have driven any distance on a run-ﬂat tire, check with an authorized run-ﬂat tire service center to determine whether the tire can be repaired or should be replaced. To maintain your vehicle’s run-ﬂat feature, all replacement tires must be self-supporting tires. As soon as possible, contact the nearest authorized GM or run-ﬂat servicing facility for inspection and repair or replacement. To locate the nearest GM or run-ﬂat servicing facility, call Roadside Assistance. For phone numbers and Roadside Service details see Roadside Assistance Program on page 7-7. { CAUTION: Run-ﬂat tires are constructed differently than other tires and could explode during improper service. You or others could be injured or killed if you CAUTION: (Continued) CAUTION: (Continued) attempt to repair, replace, dismount, or mount a run-ﬂat tire. Let only an authorized run-ﬂat service center repair, replace, dismount, and mount run-ﬂat tires. The valve stems on your run-ﬂat tires have sensors that are part of the Tire Pressure Monitor System (TPMS). See Tire Pressure Monitor System on page 5-73. These sensors contain batteries which are designed to last for 10 years under normal driving conditions. See your dealer/retailer if you ever need to have a wheel replaced, or if the sensors ever need replacement. Notice: Using liquid sealants can damage the tire valves and tire pressure monitor sensors in the vehicle’s run-ﬂat tires. This damage would not be covered by warranty. Do not use liquid sealants in the vehicle’s run-ﬂat tires. 5-70 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 4-23. 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. 5-71 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. 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. 5-72 If you will be driving your vehicle at speeds of 175 mph (282 km/h) or higher, where it is legal, set the cold inﬂation pressure to the maximum inﬂation pressure shown on the tire sidewall, or 38 psi (265 kPa), whichever is lower. See the example following. When you end this high-speed driving, return the tires to the cold inﬂation pressure shown on the Tire and Loading Information label. See Loading the Vehicle on page 4-23. 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 38 psi (265 kPa). Racing or other competitive driving may affect the warranty coverage of your vehicle. See your warranty booklet for more information. 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 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. 5-73 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 5-75 for additional information. 5-74 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 on your vehicle. 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. When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light, located in 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 appear 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 3-50 and DIC Warnings and Messages on page 3-56. 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, attached to your vehicle, shows the size of your vehicle’s original equipment tires and the correct inﬂation pressure for your vehicle’s tires when they are cold. See Loading the Vehicle on page 4-23, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inﬂation - Tire Pressure on page 5-71 for additional information. 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 5-77, When It Is Time for New Tires on page 5-77, and Tires on page 5-62. Notice: Liquid tire sealants could damage the Tire Pressure Monitor System (TPMS) sensors. Sensor damage caused by using a tire sealant is not covered by your warranty. Do not use liquid tire sealants. 5-75 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: The TPMS sensor matching process was not done or not completed successfully. The DIC message should go off after successfully completing the sensor matching process. (cid:129) One or more TPMS sensors are missing or damaged. Under these conditions the TPMS malfunction light (low tire warning light) comes on, and at the same time the DIC message is displayed. The DIC message and TPMS malfunction light should go off once the TPMS sensors are installed and the sensor matching process is performed successfully. (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 5-78. (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. 5-76 (cid:129) 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. 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 will need to be matched to the new tire/wheel position. The sensors are matched to the tire/wheel positions in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service. Tire Inspection and Rotation We recommend that you regularly inspect your vehicle’s tires for signs of wear or damage Also check for damaged wheels. See When It Is Time for New Tires on page 5-77 and Wheel Replacement on page 5-82. The tires on your vehicle are different sizes front to rear. Due to this, the tires should not be rotated. Each tire and wheel should be used only in the position it is in. 5-77 You need a new tire 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. 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 5-64, for additional information. 5-78 (cid:129) (cid:129) (cid:129) 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 5-77. 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 5-73. Your vehicle’s original equipment tires are listed on the Tire and Loading Information label. See Loading the Vehicle on page 4-23, for more information about the Tire and Loading Information label and its location on your vehicle. 5-79 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 5-78 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. 5-80 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. 5-81 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 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. 5-82 { 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. 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. 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. 5-83 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. Tighten the wheel lug nuts ﬁrmly in a crisscross sequence as shown. Tightening Wheel Lug Nuts { 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. { CAUTION: 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. 5-84 Tire Chains { CAUTION: Do not use tire chains. There is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension, or other vehicle parts. The area damaged by the tire chains could cause you to lose control of the vehicle and you or others may be injured in a crash. Use another type of CAUTION: (Continued) CAUTION: (Continued) 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. 5-85 Lifting the Vehicle { CAUTION: Lifting a vehicle can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to lift your vehicle. To help prevent the vehicle from moving: 1. Set the parking brake ﬁrmly. 2. Put an automatic transmission shift lever in P (Park), or shift a manual transmission to 1 (First) or R (Reverse). 3. Turn off the engine. To be even more certain the vehicle won’t move, you can put blocks in front of and behind the wheels. { 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 the vehicle with the jack improperly positioned can damage the vehicle or the vehicle may fall and cause your or others injury. 5-86 If you ever use a jack to lift your vehicle, follow the instructions that came with the jack, and be sure to use the correct lifting points to avoid damaging your vehicle. Notice: Lifting your vehicle improperly can damage your vehicle and result in costly repairs not covered by your warranty. To lift your vehicle properly, follow the advice in this part. To help prevent vehicle damage: (cid:129) Be sure to place a block or pad between the jack and the vehicle. (cid:129) Make sure the jack you are using spans at least two crossmember ribs. Lift only in the areas shown in the following pictures. For additional information, see your dealer/retailer and the Chevrolet Corvette service manual. Lifting From the Front The front lifting points can be accessed from either side of your vehicle, behind the front tires. 5-87 (cid:129) 1. Locate the front lifting points (A), according to the illustration shown. 3. Lift the vehicle with the jack, making sure the jack spans at least two of the crossmember ribs (B). 2. Be sure to place a block or pad between the jack and the vehicle. 5-88 Lifting From the Rear The rear lifting points can be accessed from the rear of the vehicle, on either the driver’s or passenger’s side. 1. Locate the rear lifting points (A), according to the illustration shown. 2. Be sure to place a block or pad between the jack and the vehicle. 5-89 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. If air goes out of a tire, it is much more likely to leak out slowly. See Tires on page 5-62 for additional information. But if you should ever have a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the ﬂat tire creates a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel ﬁrmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. 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. The vehicle has no spare tire, no tire changing equipment, and no place to store a tire. 3. Lift the vehicle with the jack, making sure the jack spans at least two of the crossmember ribs (B). For more information, see Doing Your Own Service Work on page 5-4. 5-90 The vehicle, when new, had run-ﬂat tires. This type of tire can operate effectively with no air pressure, so you will not need to stop on the side of the road to change a ﬂat tire. You can just keep on driving. The shorter the distance you drive and the slower the speed, the greater the chance that the run-ﬂat tire will not have to be replaced. Run-ﬂat tires perform so well without any air that a Tire Pressure Monitor System (TPMS) is used to alert you if a tire has lost pressure. See Run-Flat Tires on page 5-69 and Tire Pressure Monitor System on page 5-73. { CAUTION: Special tools and procedures are required to service a run-ﬂat tire. If these special tools and procedures are not used you or others could be injured and the vehicle could be damaged. Always be sure the proper tools and procedures, as described in the service manual, are used. To order a service manual, see Service Publications Ordering Information on page 7-16. 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. 5-91 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. 5-92 (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. 5-93 (cid:129) (cid:129) Coated Moldings These moldings are around the hatch opening in the rear area. (cid:129) When lightly soiled, wipe with a sponge or soft lint-free cloth dampened with water. (cid:129) When heavily soiled, use warm soapy water. 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. Cargo Cover and Convenience Net Wash with warm water and mild detergent, rinse with cold water and tumble dry on low. Do not use chlorine bleach. 5-94 Care of Safety Belts Keep belts clean and dry. { CAUTION: Do not bleach or dye safety belts. It may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather frequent application may be required. See Recommended Fluids and Lubricants on page 6-12. Washing Your Vehicle The best way to preserve your vehicle’s ﬁnish is to keep it clean by washing it often. Notice: Certain cleaners contain chemicals that can damage the emblems or nameplates on the vehicle. Check the cleaning product label. If it states that it should not be used on plastic parts, do not use it on the vehicle or damage may occur and it would not be covered by the warranty. Do not wash the vehicle in direct sunlight. Use a car washing soap. Do not use cleaning agents that are petroleum based or that contain acid or abrasives, as they can damage the paint, metal or plastic on your vehicle. Approved cleaning products can be obtained from your dealer/retailer. Follow all manufacturers’ directions regarding correct product usage, necessary safety precautions and appropriate disposal of any vehicle care product. 5-95 If you drive the vehicle through an Rinse the vehicle well, before washing and after to remove all cleaning agents completely. If they are allowed to dry on the surface, they could stain. Dry the ﬁnish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. Notice: automatic car wash that does not have enough clearance for the wide rear tires and wheels, you could damage the vehicle. Verify with the manager of the car wash that the vehicle will ﬁt before entering the car wash or use a touchless car wash. High pressure car washes may cause water to enter the vehicle. Avoid using high pressure washes closer than 12 inches (30 cm) to the surface of the vehicle. Use of power washers exceeding 1,200 psi (8 274 kPa) can result in damage or removal of paint and decals. Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 5-95. Finish Care Occasional waxing or mild polishing of the vehicle by hand may be necessary to remove residue from the paint ﬁnish. Approved cleaning products can be obtained from your dealer/retailer. If the vehicle has a basecoat/clearcoat paint ﬁnish, the clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint ﬁnish. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint ﬁnish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint ﬁnish on the vehicle. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage the vehicle’s ﬁnish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. To help keep the paint ﬁnish looking new, keep the vehicle garaged or covered whenever possible. 5-96 Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, chrome polish may be used on chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts. ZR1 Carbon Fiber Panels Carbon ﬁber panels can be washed and waxed like any other panels. Use a clear or black pigmented wax on the inner hood carbon ﬁber panel. ZR1 Hood Window The hood window on the ZR1 can be cleaned in the same manner as the headlamp lenses. See Cleaning Exterior Lamps/Lenses on page 5-96 for more information. Windshield and Wiper Blades Clean the outside of the windshield with glass cleaner. Clean the rubber blades using a lint free cloth or paper towel soaked with windshield washer ﬂuid or a mild detergent. Wash the windshield thoroughly when cleaning the blades. Bugs, road grime, sap, and a buildup of vehicle wash/wax treatments may cause wiper streaking. Replace the wiper blades if they are worn or damaged. Wipers can be damaged by: (cid:129) Extreme dusty conditions (cid:129) Sand and salt (cid:129) Heat and sun (cid:129) Snow and ice, without proper removal 5-97 If you use a glass treatment and/or Removable Roof Panel Notice: conditioner that contains ethyl alcohol or ethyl sulfate on the roof panel, you could damage the panel. The repairs would not be covered by your warranty. Only use a GM-approved glass cleaner on the roof panel. Special care is necessary when cleaning, removing, and/or storing the roof panel. Flush with water to remove dust and dirt, then dry the panel. (cid:129) Clean a transparent roof panel with GM Glass Cleaner. Leave the cleaner on the panel for one minute, then wipe the panel with a soft, lint-free cloth. Do not use glass cleaner on a painted roof panel. (cid:129) Do not use abrasive cleaning materials on either type of panel. If water drops are frequently allowed to dry on the roof panel, impurities in the water will adhere to the top. These impurities may etch or mar the ﬁnish. When the panel gets wet, dry it off. Convertible Top The vehicle’s convertible top should be cleaned often. However, high pressure car washes may cause water to enter your vehicle. When you hand wash the top, do it in partial shade. Use a mild soap, lukewarm water and a soft sponge. A chamois or cloth may leave lint on the top, and a brush can chafe the threads in the top fabric. Do not use detergents, harsh cleaners, solvents or bleaching agents. Wet the entire vehicle and wash the top evenly to avoid spots or rings. Let the soap remain on the fabric for a few minutes. When the top is really dirty, use a mild foam-type cleaner. Thoroughly rinse the entire vehicle, then let the top dry in direct sunlight. To protect the convertible top: (cid:129) After you wash the vehicle, make sure the top is completely dry before you lower it. (cid:129) Do not get any cleaner on the vehicle’s painted ﬁnish; it could leave streaks. If you decide to go through an automatic car wash, ask the manager if the equipment could damage your top. 5-98 (cid:129) (cid:129) Aluminum or Chrome-Plated Wheels and Trim The vehicle may have either aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. Notice: Chrome wheels and other chrome trim may be damaged if the vehicle is not washed after driving on roads that have been sprayed with magnesium, calcium or sodium chloride. These chlorides are used on roads for conditions such as ice and dust. Always wash the vehicle’s chrome with soap and water after exposure. Notice: Using strong soaps, chemicals, abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, could damage the surface of the wheel(s). The repairs would not be covered by the vehicle warranty. Use only approved cleaners on aluminum or chrome-plated wheels. The surface of these wheels is similar to the painted surface of the vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because they could damage the surface. Do not use chrome polish on aluminum wheels. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by the vehicle warranty. Use chrome polish on chrome wheels only. Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. Notice: Driving the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes, could damage the aluminum or chrome-plated wheels. The repairs would not be covered by the vehicle warranty. Never drive a vehicle that has aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. 5-99 Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on the vehicle may damage the paint ﬁnish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on the vehicle. Finish Damage Any stone chips, fractures or deep scratches in the ﬁnish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your dealer/retailer. Larger areas of ﬁnish damage can be corrected in your dealer’s/ retailer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, ﬂoor pan, and exhaust system even though they have corrosion protection. At least every spring, ﬂush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being ﬂushed. Your dealer/retailer or an underbody car washing system can do this. Fiberglass Springs (Composite Springs) Notice: products, engine degreasers or aluminum cleaning agents on ﬁberglass springs, you may damage the springs. The repairs would not be covered by your warranty. Use only approved cleaners when cleaning your vehicle’s ﬁberglass springs. If you use acidic or corrosive cleaning 5-100 Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, we will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs ﬁrst. Vehicle Identiﬁcation Vehicle Identiﬁcation Number (VIN) This is the legal identiﬁer for the vehicle. It appears on a plate in the front corner of the instrument panel, on the driver side. It can be seen through the windshield from outside the vehicle. The VIN also appears on the Vehicle Certiﬁcation and Service Parts labels and the certiﬁcates of title and registration. 5-101 Engine Identiﬁcation The eighth character in the VIN is the engine code. This code helps identify the vehicle’s engine, speciﬁcations, and replacement parts. See “Engine Speciﬁcations” under Capacities and Speciﬁcations on page 5-110 for the vehicle’s engine code. Service Parts Identiﬁcation Label This label is on the inside of the glove box. It is very helpful if parts need to be ordered. The label has the following information: (cid:129) Vehicle Identiﬁcation Number (VIN) (cid:129) Model designation (cid:129) Paint information (cid:129) Production options and special equipment Do not remove this label from the vehicle. Electrical System Add-On Electrical Equipment Notice: Do not add anything electrical to the vehicle unless you check with your dealer/retailer ﬁrst. Some electrical equipment can damage the vehicle and the damage would not be covered by the vehicle’s warranty. Some add-on electrical equipment can keep other components from working as they should. Add-on equipment can drain the vehicle battery, even if the vehicle is not operating. The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-56. Headlamp Wiring The headlamp wiring is protected by fuses in the fuse block. An electrical overload will cause the lamps to turn off. If this happens, have the headlamp wiring checked right away. 5-102 Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it ﬁxed. Power Windows and Other Power Options Circuit breakers protect the power seats, power windows, and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is ﬁxed or goes away. Fuses and Circuit Breakers The wiring circuits in the vehicle are protected from short circuits by a combination of J-Case fuses, mini-fuses and circuit breakers. This greatly reduces the chance of ﬁres caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and do not have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of the vehicle that you can get along without – like the radio or cigarette lighter – and use its fuse, if it is the correct amperage. Replace it as soon as you can. Vehicles with the ZR–1 package have an intercooler relay located on the fan shroud. See your dealer/retailer. Vehicles with the ZR–1 package also have a fuel system mini-fuse. It is located near the battery in the battery storage compartment in the rear of the vehicle. Instrument Panel Fuse Block The instrument panel fuse block is located on the passenger side of the vehicle, under the instrument panel and under the toe-board. Remove the carpet and toe-board covering to access the fuse block by pulling at the top of each corner of the panel. Open the fuse block cover to access the fuses. You can remove fuses using the fuse puller. 5-103 Fuses Usage BCK/UP LAMP Reverse Lamps BLANK BLANK Not Used Not Used Fuses Usage BTSI SOL/STR WHL LCK CLSTR/HUD Brake Transmission Shift Interlock, Steering Wheel Column Lock Cluster, Heads-Up Display 5-104 Fuses CRUISE SWITCH CTSY/LAMP DR LCK DRIV DR SWITCH ECM EXH MDL GM LAN RUN/CRNK HTD SEAT/ WPR RLY HVAC/ PWR SND IGN SWTCH/ INTR SNSR ISRVM/HVAC ONSTAR RDO/S-BAND/ VICS REAR FOG/ ALDL/TOP SWTCH Usage Cruise Control Switch Courtesy Lamp Door Locks Driver Door Switch Engine Control Module (ECM) Exhaust Module (Z06), Spare (Coupe and Convertible) GM LAN Devices Heated Seat, Wiper Relays Heating.
