Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km)
for any signs of unusual wear. If unusual wear is present, rotate your tires as
soon as possible and check wheel alignment. Also check for damaged tires
or wheels. See “When It’s Time for New Tires” and “Wheel Replacement”
later in this section for more information.
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 Services”
in the Index for scheduled rotation intervals.

rotating your
tires, always use one of the correct rotation
patterns shown here.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the Certificatioflire label. Make certain that
all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.

system. Look for broken, damaged, missing or out-of-position parts as we1
as open seams, holes, loose connections, or other conditions which could
cause a heat build-up in
the floor pan or could let exhaust fumes into the
vehicle. See “Engine Exhaust” in the Index.
Accelerator Control System
Lubricate all pivot points with engine oil, except the TBI throttle shaft. Do
not lubricate the cam pulley. Remove all external deposits from pulley. Do
