Scheduled Maintenance
When the CHANGE OIL SOON message on the
Driver Information Center (DIC) comes on, it
means that service is required for your vehicle.
See DIC Warnings and Messages on page 147.
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 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 Life System
on page 250 for information on the Engine Oil Life
System and resetting the system.
When the CHANGE 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 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 OIL SOON 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
CHANGE OIL SOON message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
