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 0 290 and Wheel Replacement 0 294. . Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI) 0 319.
. Lubricate body components. See Exterior Care 0 307.
Additional Required Services — Normal Service Every 12 000 km (7,500 mi)
. Check the engine oil level and oil
life percentage. If needed, change engine the oil and filter, and reset oil the life system. Or when the CHANGE ENGINE OIL SOON message displays, have the engine oil and filter changed within the next 1 000 km/600 mi. If driven under the best conditions, the engine oil life system may not indicate the need for vehicle service for up to a year. The engine oil and filter must be changed at least once a year and the oil life system must be reset. Your trained dealer technician can perform this work. If the engine oil life system is reset accidentally, service the vehicle within 5 000 km/3,000 mi since the last service.
