Maintenance Schedule
Tire Rotation and Required Services Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform wear for all tires. The first rotation is the most important. Anytime unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels. If the unusual wear continues after the rotation, check the
wheel alignment. See When It Is Time for New Tires 0 366 and Wheel Replacement 0 370. . Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI) 0 402.
