Maintenance Schedule
I
Follow this maintenance schedule
only
if
none
of
the
conditions from the Short Trip/City Maintenance
Schedule is true. Do not use this schedule
if
the vehicle
is used for trailer towing, driven in a dusty area or used
off paved roads. Use the Short Trip/City schedule for
these conditions.
Driving a vehicle with a fully warmed engine under
highway conditions causes engine oil
to
break
down slower.
