To purchase service information,
see Service Publications Ordering
Information on page 7-15.
Owner Checks and Services on
page 6-9 tells 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,
fluids, and lubricants to use are
listed in Recommended Fluids
and Lubricants on page 6-12 and
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
filter 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. See Engine Oil Life
System on page 5-15 for 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 “Maintenance I” and
“Maintenance II.” Generally, it is
recommended that the first service
be Maintenance I, the second
service be Maintenance II, and
then alternate Maintenance I and
Maintenance II thereafter. However,
in some cases, Maintenance II may
be required more often.
