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 completesthe calibration process during driving. The system "learns" the pressure at eachtire 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), 40to 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 completedduring a single trip. Once learned, the systemwill remember thetire pressure until the system is reset. 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" in Changing a Flat Tire on page 5-67. 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 "Part A: Scheduled Maintenance Services," in Section 6, for scheduled rotation intervals. Tire Inspection and Rotation Tires should be rotated every 7,500 miles (12 500 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 5-59 and Wheel Replacement on page 5-62 for more information. 5-58 When rotating your tires, always use the correct rotation pattern shown here. Don't include the compact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certificationflire label.
