2007 CHEVROLET EXPRESS PASSANGER check engine light

Scheduled Maintenance
(Gasoline Engine)
This maintenance section applies to vehicles with
a gasoline engine. If your vehicle has a diesel
engine, see the maintenance schedule section in
the DURAMAX
®Diesel Engine Supplement.
When the change engine oil light 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 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
(Gasoline Engine) on page 306for information
on the Engine Oil Life System and resetting the
system.
When the change engine oil light 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 first
service be MaintenanceI, your second service
be MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay
be required more often.
405

MaintenanceI— Use MaintenanceIif the
change engine oil light 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.
