Owner's Manual

Scheduled Maintenance
When the CHG OIL message in the message
center comes on, it means that service is required
for your vehicle. See Change Engine Oil
Message on page 183. 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 Life System on
page 288 for information on the Engine Oil Life
System and resetting the system.
When the CHG 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.
