Scheduled Maintenance
When the Service Engine Oil
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 may not
indicate that vehicle service is
necessary for over a year. However,
your 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, 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. See Engine Oil Life
System on page 9-10 for information
on the Engine Oil Life System
and resetting the system.
When the Service Engine Oil
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 your first service
be Maintenance I, your second
service be Maintenance II, and that
you alternate Maintenance I and
Maintenance II thereafter. However,
in some cases, Maintenance II
may be required more often.
Maintenance I — Use
Maintenance I if the Service Engine
Oil message comes on within
10 months since the vehicle was
purchased or Maintenance II
was performed.
Maintenance II — Use
Maintenance II if the previous
service performed was
Maintenance I. Always use
Maintenance II whenever the
Service Engine Oil message comes
on 10 months or more since the
last service or if the message
has not come on at all for one year.
