Maintenance and care 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. 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. SERVICING YOUR TIRES Low tire warning (if equipped) The low tire warning system is designed to detect a significant loss of inflation in any one of your tires on your vehicle. The system uses the Anti-lock brake wheel speed sensors to detect a change in wheel speed due to tire deflation. When a tire loses inflation, the low tire warning system detects the change and illuminates the low tire warning indicator light as shown. If the light remains on while driving, check the tire pressure refer to "Checking the tire pressure" in this chapter. The low tire warning indicator light will also illuminate when using a temporary spare, refer to "Changing the tires" in this chapter. The low tire warning system may not detect an under-inflated tire under all conditions and is not a substitute for manually checking tires regularly for proper inflation. The low tire warning system should be reset whenever new tires are installed, rotated or tire pressures are changed. To reset the system, turn the ignition to the ON position, press Tire Reset and hold the "TIRE RESET" switch for three seconds. The low tire warning indicator light will flash three times as the low tire warning system begins to initialize. The 232
