Check Tire Pressure System If your vehicle has the check tire pressure system, it can alert you to a large change in the pressure of one tire. The system will not alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly. The CHECK TIRE PRESSURE message will appear on the Driver Information Center (DIC) if pressure difference (low pressure) is detected in one tire. The check tire pressure system may not alert you if: The check tire pressure system detects differences in tire rotation speeds that are caused by changes in tire pressure. The system can alert you about a low tire - but it does not replace normal tire maintenance. See Tires on page 5-54. When the CHECK TIRE PRESSURE message appears on the Driver Information Center, you should stop as soon as you can and check all your tires for damage. If a tire is flat, see If a Tire Goes Flat on page 5-69. Also check the tire pressure in all four tires as soon as you can. See Inflation - Tire Pressure on page 5-60. Any time you adjust a tire's pressure or have one or more tires repaired or replaced, you will need to reset (calibrate) the check tire pressure system. You will also need to reset the system whenever you rotate the tires, buy new tires and install or remove the compact spare tire. Do not reset the check tire pressure system without first correcting the cause of the problem and checking and adjusting the pressure in all four tires. If you reset the system when the tire pressures are incorrect, the check tire pressure system will not work properly and may not alert you when a tire is low or high. • More than one tire is low. • The vehicle is moving faster than 65 mph (105 km/h). The system is not yet calibrated. The tire treadwear is uneven. The compact spare tire is installed. Tire chains are being used. The vehicle is being driven on a rough or frozen road. If the anti-lock brake system warning light comes on, the check tire pressure system may not be working properly. See your dealer for service. Also, see Anti-Lock Brake System Warning Light on page 3-39. 5-62
