Scheduled Maintenance - GMC 2005 Savana Van Owner's Manual

When you go to your GM Goodwrench dealer for your
service needs, you will know that GM-trained and
supported service technicians will perform the work
using genuine GM parts.
If you want to purchase service information, see Service
Publications Ordering Information on page 7-13.
Owner Checks and Services on page 6-10 tells 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, fluids and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 6-13 and Normal Maintenance Replacement
Parts on page 6-15. 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 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 GM
Goodwrench dealer has GM-trained service technicians
who will perform this work using genuine GM 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. See
Engine Oil Life System on page 5-16 for 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
"Maintenance I" and "Maintenance II." Generally, it is
recommended that your first service be Maintenance I,
your second service be Maintenance II and that you
alternate Maintenance I and Maintenance II thereafter.
However, in some cases, Maintenance II may be
required more often.
