warning light GMC ENVOY 2008 Owner's Guide

When you go to your dealer/retailer for your service
needs, you will know that trained and supported service
technicians will perform the work using genuine parts.
If you want to purchase service information, seeService
Publications Ordering Information on page 7-16.
Owner Checks and Services on page 6-9tells 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 6-12andMaintenance Replacement Parts
on page 6-14. 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
parts from your dealer/retailer.
Scheduled Maintenance
When the change engine oil light or CHANGE ENGINE
OIL DIC message comes on, it means that service is
required for your vehicle. SeeChange Engine Oil Light
on page 3-45orDIC Warnings and Messages on
page 3-53. 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 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 5-19for information on the Engine Oil
Life System and resetting the system.
When the change engine oil light or CHANGE ENGINE
OIL DIC 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 MaintenanceI
and MaintenanceIIthereafter. However, in some cases,
MaintenanceIImay be required more often.
MaintenanceI— Use MaintenanceIif the light or
message comes on within 10 months since the vehicle
was purchased or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the light or message comes
on 10 months or more since the last service or if the light
or message has not come on at all for one year.
