Detection thresholds may be higher and detection times may be longer on rough roads, curves and at high speeds. The system is not capable of inflation differences at speeds greater than 70 mph (110 km/h). The tire inflation monitor system will not alert you if the pressure in more than one tire is low, if the system is not properly calibrated, or if the vehicle is moving faster than 70 mph (110 km/h). The LOW TIRE light will stay on while the ignition is on, until the system is reset Do not reset the tire inflation monitor system without first correcting the cause of the problem and checking and adjusting the pressure in all four tires. If the system is reset when the tire pressures are incorrect, it will not function properly and may not alert you when a tire is low. Any time a tire's pressure is adjusted, the tires are rotated, or one or more tires is repaired or replaced, the tire inflation monitor system will need to be reset. The system also needs to be reset when new tires are purchased and if the vehicle's battery has been disconnected. To reset the system: 1. Turn the ignition to RUN. 2. Remove the passenger's side instrument panel cover to get to the fuse block. 3. Press and hold the RESET button in the fuse block for about five seconds. 4. The LOW TIRE light will come on and flash three times. Then it will go off. If the light does not go off, see your dealer for service. Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-72 and Wheel Replacement on page 5-75 for more information. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Scheduled Maintenance on page 6-4 for scheduled rotation intervals. 5-70
