Maintenance

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 we breathe.
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 4-16.

page 6-6andMaintenance
Footnotes on page 6-7for further
information.

{CAUTION
Performing maintenance work on
a vehicle can be dangerous. In
trying to do some jobs, you can
be seriously injured. Do your own
maintenance work only if you
have the required know-how and
the proper tools and equipment
for the job. If you have any doubt,
see your dealer/retailer to have a
qualied technician do the work.
SeeDoing Your Own Service
Work on page 5-4.
Some maintenance services can
be complex. So, unless you
are technically qualied and have
the necessary equipment, have
your dealer/retailer do these jobs.When you go to your dealer/retailer
for service, trained and supported
service technicians will perform
the work using genuine parts.
To purchase service information,
seeService Publications Ordering
Information on page 7-15.
Owner Checks and Services on
page 6-9tells what should be
checked, when to check it, and what
can easily be done to help keep
the vehicle in good condition.
The proper replacement parts, uids,
and lubricants to use are listed in
Recommended Fluids and
Lubricants on page 6-12and
Maintenance Replacement Parts on
page 6-14. When the 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 displays, service is
required for the vehicle. Have the
vehicle serviced as soon as possible
within the next 600 miles (1 000 km).
It is possible that, if 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.
Maintenance Schedule 6-3

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. SeeEngine Oil Life
System on page 5-13for 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 the rst service
be MaintenanceI, the second
service be MaintenanceII, and then
alternate MaintenanceIand
MaintenanceIIthereafter. However,
in some cases, MaintenanceIImay
be required more often.MaintenanceI—Use

for one year.
