Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level
and change as recommended.
Maintenance Requirements
Notice:Maintenance intervals, checks,
inspections, replacement parts, and
recommended uids and lubricants as
prescribed in this manual are necessary to keep
your vehicle in good working condition. Any
damage caused by failure to follow scheduled
maintenance might not be covered by warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to
keep your 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 we breathe. Improper uid levels or the wrong
tire in ation can increase the level of emissions
from your vehicle. To help protect our environment,
and to keep your vehicle in good condition,
be sure to maintain your vehicle properly.
Using the Maintenance Schedule
We want to help you keep your 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
your vehicle in making deliveries. Or you might
drive it to work, to do errands, or in many
other ways.

Owner Checks and Services on page 493tells
you what should be checked, when to check it,
and what you can easily do to help keep your
vehicle in good condition.
The proper replacement parts, uids, and
lubricants to use are listed inRecommended
Fluids and Lubricants on page 497andNormal
Maintenance Replacement Parts on page 498.
When your vehicle is serviced, make sure these
are used. All parts should be replaced and all
necessary repairs done before you or anyone
else drives the vehicle. We recommend the use
of genuine parts from your dealer/retailer.Scheduled Maintenance
When the CHANGE ENGINE OIL SOON message
comes on, it means that service is required for your
vehicle. Have your vehicle serviced as soon as
possible within the next 600 miles (1 000 km).
It is possible that, if you are driving under the best
conditions, the engine oil life system might not
indicate that vehicle service is necessary for over
a year. However, 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, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 390for information on the Engine Oil Life
System and resetting the system.

When the CHANGE ENGINE OIL SOON message
appears, certain services, checks, and inspections
are required. Required services are described
in the following for “MaintenanceI” and
“MaintenanceII.” Generally, it is recommended
that your rst service be MaintenanceI, your
second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases,
MaintenanceIImay be required more often.MaintenanceI— Use MaintenanceIif the
CHANGE ENGINE OIL SOON message comes on
within 10 months since the vehicle was purchased
or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the message
comes on 10 months or more since the last
service or if the message has not come on at
all for one year.
