Saturn 2004 L-Series - Manual (Page 348)

Scheduled Maintenance
When the Change Engine Oil light 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 Saturn retailer has Saturn-trained
service technicians who will perform this work using
genuine Saturn 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 on page 5-16 for information on the Engine
Oil Life System and resetting the system.
When the Change Engine Oil light 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 Change
Engine Oil light comes on within ten months since
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 comes on ten months
or more since the last service or if the light has not
come on at all for one year.
