Scheduled Maintenance
When the change engine oil light or CHANGE OIL
SOON DIC 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, 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,
you must service your 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 5-21 for information on
the Engine Oil Life System and resetting the system.
When the light or 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 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 light or
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 light or message comes
on 10 months or more since the last service or if the light
or message has not come on at all for one year.
