General Information
Caution
Maintenance intervals, checks,
inspections, recommended fluids,
and lubricants are necessary to
keep this vehicle in good working
condition. Damage caused by
failure to follow scheduled
maintenance might not be
covered by the vehicle warranty.
As the vehicle owner, you are
responsible for the scheduled
maintenance in this section. We
recommend having your dealer
perform these services. Proper
vehicle maintenance helps to keep
the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions for
better air quality.
Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under Scheduled Maintenance. To keep
the vehicle in good condition, see
your dealer.
The maintenance schedule is for
vehicles that:
.
Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. See Vehicle Load Limits
0 189.
. Are driven on reasonable road
surfaces within legal driving
limits.
. Use the recommended fuel. See
Fuel 0240.
{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 to
have a qualified technician do the
work. See Doing Your Own
Service Work 0251.

Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires
on the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
service. See Tire Rotation 0299.Maintenance

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/

.Vehicles that are regularly used
for short trips of 6 kilometers
or less
If your vehicle has an Oil Life
Indicator, the indicator will show
you when to change the oil and
filter. Under severe conditions
the indicator may come on
before 10 000 km/6,000 mi. The
indicator won't detect dust in the
oil, so if you drive in a dusty
area you may have to change
the oil and filter sooner than
every 10 000 km/6,000 mi.
Note: All vehicles with
rear-wheel drive —change
driveline axle oil every
30 000 km/19,000 mi if vehicle is
used for towing purposes.
* Footnote: Under extreme
driving conditions listed above, it
may be necessary to replace
your spark plugs at more
frequent intervals. For further
assistance in determining the
most suitable service
maintenance intervals for your
vehicle, please contact your
authorized GM Dealer.Additional Required Services
