CHEVROLET 2009 Malibu - Manual (Page 372)

Scheduled Maintenance
When the CHANGE OIL SOON message displays in
the Driver Information Center (DIC), 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 5-24 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 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 message displays
10 months or more since the last service or if the
message has not come on at all for one year.
