Maintenance Schedule 6-1

Maintenance
Requirements
Notice:Maintenance intervals,
checks, inspections, replacement
parts, and recommended uids
and lubricants as prescribed
in this manual are necessary to
keep this vehicle in good working
condition. Any damage caused
by failure to follow scheduled
maintenance might not be
covered by the vehicle warranty.
Your Vehicle and the
Environment
Proper vehicle maintenance not only
helps to keep the vehicle in good
working condition, but also helps the
environment. All recommended
maintenance is important. Improper
vehicle maintenance can even
affect the quality of the air webreathe. Improper uid levels or the
wrong tire ination can increase
the level of emissions from the
vehicle. To help protect the
environment, and to keep the
vehicle in good condition, be sure to
maintain the vehicle properly.
Using the Maintenance
Schedule
We want to help keep this vehicle in
good working condition. But we
do not know exactly how you
will drive it. You might drive very
short distances only a few times a
week. Or you might drive long
distances all the time in very hot,
dusty weather. You might use
the vehicle in making deliveries.
Or you might drive it to work, to do
errands, or in many other ways.Because of all the different ways
people use their vehicles,
maintenance needs vary. You might
need more frequent checks and
replacements. So please read the
following and note how you drive.
If you have any questions on how to
keep the vehicle in good condition,
see your dealer/retailer.
This schedule is for vehicles that:carry passengers and cargo
within recommended limits on the
Tire and Loading Information
label. SeeLoading the Vehicle
on page 4-35.

the engine oil and lter must be
changed at least once a year and
at this time the system must be
reset. Your dealer/retailer has
trained service technicians who will
perform this work using genuine
parts and reset the system.If the engine oil life system is ever
reset accidentally, service the
vehicle within 3,000 miles
(5 000 km) since the last service.
Remember to reset the oil life
system whenever the oil is changed.
