Maintenance Schedule
Caution
Damage caused by improper maintenance
can lead to costly repairs and may not be
covered by the vehicle warranty.
Maintenance intervals, checks,
inspections, recommended fluids, and
lubricants are important to keep the
vehicle in good working condition.
Do not have chemical flushes that are not
approved by GM performed on the
vehicle. The use of flushes, solvents,
cleaners, or lubricants that are not
approved by GM could damage the
vehicle, requiring expensive repairs that
are not covered by the vehicle warranty.
Make sure the vehicle is inspected at regular
intervals. Inspections and maintenance
enable you to use the vehicle with peace of
mind. They also extend the vehicle's
service life.
For safe and economical driving, we
recommend that you have your vehicle
inspected and serviced regularly according to
the schedule indicated in this chapter.
To drive your vehicle safely and at minimum
cost, it is essential to have your vehicle
regularly inspected and serviced at your
dealer as per the specified maintenance
schedule.
Contact your dealer for inspection that
requires disassembly and/or special
equipment.
The Maintenance Schedule in this manual
and a Warranty Information Booklet are
supplied with your vehicle. Read all
publications for a full understanding of your
vehicle's maintenance needs.
The quality of maintenance your new
vehicle receives is as important as the
regularity with which it is serviced.
Authorized dealers provide nationwide
quality in customer service. The program
includes the training of dealer technicians
throughout the country and is supported
with a continuous follow-up of publications
and other service information. The use of
genuine parts and accessories, which have
the same high quality standards as original
equipment parts, and the use of factory
approved tools developed and tested for use
by the authorized dealer also contribute to
the high quality of service.
