254 STARTING AND OPERATING Tires may also cause the vehicle to pull left or right. Alignment will not correct this problem. See your dealer for proper diagnosis of the problem. Improper alignment will not normally cause vehicle vibration, which may be a result of tire and wheel out-of-balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear. TIRE PRESSURE MONITOR SYSTEM - IF EQUIPPED The Tire Pressure Monitor System (TPM) monitors the pressure in all 4 road tires and the full size spare. The TPM system uses wireless technology to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to a receiver located in the overhead console. The tire pressure status is shown in the Electronic Vehicle Information Center (EVIC) display. Refer to "Overhead Console" in Section 3 for more information. The TPM system functions even when the EVIC is not set on the tire pressure display screen. The TPM system informs you of a low or high tire pressure condition. If this occurs, correct your tire inflation pressure as soon as possible, and inspect all of your tires. Be sure to use a high quality gauge when adjusting pressure. The TPM system is designed to monitor your tire pressure but will not function as a tire pressure gauge. There will be a delay between the instant you adjust the air pressure in a tire and when the system updates the display. The TPM system is not intended to provide you with notification of rapid air loss.
