check engine CHEVROLET MALIBU 2007 6.G Service Manual

Owner Checks and Services on page 464tells you
what should be checked, when to check it, and
what you can easily do to help keep your vehicle
in good condition.
The proper replacement parts, uids, and lubricants
to use are listed inRecommended Fluids and
Lubricants on page 468andNormal Maintenance
Replacement Parts on page 469. When your
vehicle is serviced, make sure these are used. All
parts should be replaced and all necessary repairs
done before you or anyone else drives the vehicle.
We recommend the use of genuine GM parts.
Scheduled Maintenance
When the CHANGE OIL SOON message in the
Driver Information Center (DIC) 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, the engine oil
and lter 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, 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. SeeEngine Oil Life System on
page 362for 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 “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst service
be MaintenanceI, your second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.
MaintenanceI— Use MaintenanceIif the
message comes on within 10 months since the
vehicle was purchased or MaintenanceII
was performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever 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.
