Scheduled Maintenance
When the CHANGE 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 GM
Goodwrench dealer has GM-trained service technicians
who will perform this work using genuine GM 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 5-18 for information on the
Engine Oil Life System and resetting the system.
When the CHANGE 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 CHANGE
ENGINE OIL message 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 message comes on ten
months or more since the last service or if the message
has not come on at all for one year.
