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. To reset the system, do the following: 1. With the engine off, turn the ignition to ON. 2. Press the MODE button until the DIC reads LOW TIRE PRESSURE. 3. Press and hold the SET button until TIRE PRESSURE NORMAL is displayed. You will hear three chimes and the LOW TIRE PRESSURE message will go off and the DIC will return to TIRE PRESSURE NORMAL. If the LOW TIRE PRESSURE message comes back on, the check tire pressure system has not reset. Repeat the procedure. The system completes the calibration process during driving. The system learns the pressure at each tire throughout the operating speed range of your vehicle. The system normally takes between 30 and 60 minutes of driving to learn the tire pressures. The system normally takes 10 to 20 minutes of driving in each speed range to learn tire pressures. The speed ranges are 20 to 40 mph (32 to 64 km/h), 40 to 60 mph (64 to 96 km/h), and above 60 mph (96 km/h). This time may be longer depending on your individual driving habits. The learning process does not need to be completed during a single trip. Once learned, the system will remember the tire pressures until the system is reset. 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 5-63 and Wheel Replacement on page 5-66 for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire, If it moves, use the folding wrench to tighten the cable. See Storing a Flat or Spare Tire and Tools on page 5-85. 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. 5-61
