Scheduled Maintenance
When the CHANGE OIL SOON 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 Life System on page 5-18 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 message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
