yellowblue 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 TIRE PRESSURE LOW: CHECK TIRES 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" 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, install or remove the compact spare, and whenever the vehicle's battery has been disconnected. Don't 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. To reset (calibrate) the system: 1. Turn the ignition switch to RUN. 2. Press the GAGE INFO button on the DIC until TIRE PRESSURE appears on the display. 3. Press and hold the DIC RESET button for about five seconds. After five seconds, the display will show TIRE PRESSURE RESET. If TIRE PRESSURE RESET does not appear in the display after about five seconds retry the process. If it does not work after two tries, see your dealer for service. After you release the DIC RESET button, TIRE PRESSURE NORMAL will appear in the display. The system completes the calibration process during driving. Calibration time can take 45 to 90 minutes, depending on your driving habits. After the system has been calibrated, the system will alert the driver that a tire is low, up to a maximum speed of 65 mph (105 km/h). 6-44
