Pontiac G5 Automobile User Manual


 
Scheduled Maintenance
When the CHANGE OIL SOON message displays,
service is required for the vehicle. Have the vehicle
serviced as soon as possible within the next 600 miles
(1 000 km). It is possible that, if 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 dealer/retailer has trained service
technicians who will perform this work using genuine
parts and reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the 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 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 the first service be
Maintenance I, the second service be Maintenance II,
and then 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 displays 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 displays 10 months or more since the last
service or if the message has not come on at all for
one year.
