Pontiac 2006 Gto - Manual (Page 284)

Scheduled Maintenance
When the Service Engine Oil message on the trip
computer display comes on, it means that service is
required for your vehicle. See
Trip Computer on
page 3-33 . 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 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 5-16 for information on
the Engine Oil Life System and resetting the system.
When the Service 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 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.
