Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166 000 km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles (240
000 km) should be performed at
the same interval after 150,000

See “Owner Checks and Services’’ and “Periodic
Maintenance Inspections” following.
Footnotes
f‘ The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at
the indicated intervals and the maintenance
be recorded.
+ A good time to check your brakes is during tire
rotation.
See “Brake System Inspection” under “Periodic
Maintenance Inspections” in Part
C of this schedule.
# Lubricate the suspension and steering linkage,
transaxle shift linkage, parking brake cable guides
and underbody contact points and linkage.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- usually between 3,000 miles (5 000 km)
and 7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12 500 km) or 12 months
without an oil and filter change.
The system won’t detect dust in the oil.
So if you drive
in
a dusty area, be sure to change your oil and filter
every
3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON message appears. Remember to reset the
Oil Life Monitor when the oil has been changed. For
more information, see “Engine Oil Life Monitor” in
the Index.
