{WARNING
Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer/
retailer to have a qualified
technician do the work.
SeeDoing Your Own Service
Work on page 9‑4.
At your General Motors dealer/
retailer, you can be certain that you
will receive the highest level of
service available. Your dealer/
retailer has specially trained
service technicians, uses genuine GM replacement parts, as well as,
up to date tools and equipment
to ensure fast and accurate
diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed in
Recommended Fluids and
Lubricants
on page 10‑7and
Maintenance Replacement Partson
page 10‑9. We recommend the
use of genuine parts from your
dealer/retailer.
Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed
when they have 8 000 to 13 000 km
(5,000 to 8,000 miles). See Tire
Rotation on page 9‑59.
Scheduled

An Emission Control Service.
When the Change Engine Oil Soon
message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 miles. If driving under the best
conditions, the engine oil life system
might not indicate the need for
vehicle service for more than a year.
The engine oil and filter must be
changed at least once a year and
the oil life system must be reset.
Your dealer/retailer has trained
service technicians who will perform
this work and reset the system.
