Check Tire Pressure System (If Equipped) The check tire pressure system can alert you to a large change in the pressure of one tire. The system won't alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly. The LOW TIRE PRESSURE HOLD SET TO RESET message will appear on the Driver Information Center (DIC) or the system monitor light will come on and the LOW TIRE PRESSURE message will come on the message center if pressure difference (low pressure) is detected in one tire. The check tire pressure system may not alert you if: 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" in the Index. 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 doesn't replace normal tire maintenance. See "Tires" in the Index. When the LOW TIRE PRESSURE HOLD SET TO RESET message appears on the Driver Information Center or the light comes on, Center and the LOW TIRE PRESSURE message comes on the message 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" in the Index. Also check the tire pressure in all four tires as soon as you can. See "Inflation-Tire Pressure" in the Index. Any time you adjust a tire's pressure or have one or more tires repaired or replaced, you'll need to reset (calibrate) the check tire pressure system. You'll also need to reset the system whenever you rotate the tires, buy new tires and install or remove the compact spare. D D D D D D D 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, or the vehicle is being driven on a rough or frozen road. 6-43
