Maintenance
Schedule
Rotate Tires and Perform
Required Services Every
12 000 km (7,500 mi)
.Rotate the tires. Rotating
the tires helps achieve a
more uniform wear. The first
rotation is the most important. Anytime you
notice unusual tire wear,
rotate the tires as soon as
possible, check for proper
tire inflation pressure, and
check for damage to tires or
wheels. If unusual wear
continues after a rotation,
check the wheel alignment.
