.Gently blot liquids with a
paper towel. Continue
blotting until no more soil
can be removed.
.For solid soils, remove as
much as possible prior to
vacuuming.
To clean: 1. Saturate a clean, lint-free colorfast cloth with water.
Microfiber cloth is
recommended to prevent
lint transfer to the fabric
or carpet.
2. Remove excess moisture by gently wringing until
water does not drip from
the cleaning cloth.
3. Start on the outside edge of the soil and gently rub
toward the center. Fold
the cleaning cloth to a
clean area frequently to
prevent forcing the soil
into the fabric. 4. Continue gently rubbing
the soiled area until there
is no longer any color
transfer from the soil to
the cleaning cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by
plain water.
If the soil is not completely
removed, it may be necessary
to use a commercial
upholstery cleaner or spot
lifter. Test a small hidden area
for colorfastness before using
a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the
entire fabric or carpet.
After cleaning, use a paper
towel to blot excess moisture.
Cleaning High Gloss
Surfaces and Vehicle
Information and Radio
Displays
Use a microfiber cloth on high
gloss surfaces or vehicle
displays. First, use a soft
bristle brush to remove dirt
that can scratch the surface.
Then gently clean by rubbing
with a microfiber cloth. Never
use window cleaners or
solvents. Periodically hand
wash the microfiber cloth
separately, using mild soap. Do
not use bleach or fabric
softener. Rinse thoroughly and
air dry before next use.
Caution
Do not attach a device with
a suction cup to the display.
This may cause damage and
would not be covered by the
vehicle warranty.

General
Information
Your vehicle is an important
investment. This section
describes the required
maintenance for the vehicle.
Follow this schedule to help
protect against major repair
expenses resulting from
neglect or inadequate
maintenance. It may also help
to maintain the value of the
vehicle if it is sold. It is the
responsibility of the owner to
have all required maintenance
performed.
Your dealer has trained
technicians who can perform
required maintenance using
genuine replacement parts.
They have up-to-date tools
and equipment for fast and
accurate diagnostics. Many
dealers have extended
evening and Saturday hours,
courtesy transportation, and
online scheduling to assist
with service needs. Your dealer recognizes the
importance of providing
competitively priced
maintenance and repair
services. With trained
technicians, the dealer is the
place for routine maintenance
such as oil changes and tire
rotations and additional
maintenance items like tires,
brakes, batteries, and wiper
blades.
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

Schedule
Tire Rotation and
Required Services Every
12 000 km (7,500 mi)
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as
soon as possible, check for
proper tire inflation pressure,
and check for damaged tires
or wheels. If the unusual wear
continues after the rotation,
check the wheel alignment.
See When It Is Time for New
Tires0431 and

STEP THREE—Canadian
Owners : In the event that you
do not feel your concerns
have been addressed after
following the procedure
outlined in Steps One and
Two, General Motors of
Canada Company wants you
to be aware of its participation
in a no-charge mediation/
arbitration program. General
Motors of Canada Company
has committed to binding arbitration of owner disputes
involving factory-related
vehicle service claims. The
program provides for the
review of the facts involved by
an impartial third party arbiter,

the entire dispute settlement
process, from the time you file
your complaint to the final
decision, should be completed
in about 70 days. We believe
our impartial program offers
