cleaning agents in higher
concentrations than
suggested by the
manufacturer.
.Solvents, alcohols, fuels,
or other harsh cleaners.
.Ice scrapers or other hard
items.
.Aftermarket appearance
caps or covers while the
lamps are illuminated, due to
excessive heat generated.
Caution
Failure to clean lamps
properly can cause damage
to the lamp cover that would
not be covered by the
vehicle warranty.
Caution
Using wax on low gloss black
finish stripes can increase
the gloss level and create a
non-uniform finish. Clean low
gloss stripes with soap and
water only.
Air Intakes
Clear debris from the air
intakes between the hood and
windshield when washing the
vehicle.
Shutter System
The vehicle may have a
shutter system designed to
help improve fuel economy.
Always keep the shutter
system clear of debris, snow
and ice. If the check engine
light is activated, please check
to see if the shutter system is
clear of debris, snow or ice.
Windshield and Wiper
Blades
Clean the outside of the
windshield with glass cleaner.
Clean rubber wiper blades
using a lint-free cloth or paper
towel soaked with windshield
washer fluid or a mild
detergent. Wash the
windshield thoroughly when
cleaning the blades. Bugs,
road grime, sap, and a buildup
of vehicle wash/wax
treatments may cause wiper

extreme dusty conditions,
sand, salt, heat, sun, snow,
and ice.
Weatherstrips
Apply weatherstrip lubricant
on weatherstrips to make
them last longer, seal better,
and not stick or squeak.
Lubricate weatherstrips at
least once a year. Hot, dry
climates may require more
frequent application. Black
marks from rubber material on
painted surfaces can be
removed by rubbing with a
clean cloth. See
Recommended Fluids and
Lubricants0474.
Tires
Use a stiff brush with tire
cleaner to clean the tires.
Caution
Using petroleum-based tire
dressing products on the
vehicle may damage the
paint finish and/or tires.
(Continued)
Caution (Continued)
When applying a tire
dressing, always wipe off
any overspray from all
painted surfaces on the
vehicle.
Wheels and Wheel Trim
Use a soft, clean cloth with
mild soap and water to clean
the wheels. After rinsing
thoroughly with clean water,
dry with a soft, clean towel.
A wax may then be applied.
Caution
Chrome wheels and chrome
wheel trim may be damaged
if the vehicle is not washed
after driving on roads that
have been sprayed with
magnesium chloride or
calcium chloride. These are
used on roads for conditions
such as dust control. Always
wash the chrome with soap
and water after exposure.
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake pads
for wear and rotors for
surface condition. Inspect
brake linings/shoes for wear
or cracks. Inspect all other
brake parts.

.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.

Managing the Vehicle
Damage Repair Process
In the event that the vehicle
requires damage repairs, GM
recommends that you take an
active role in its repair. If you
have a pre-determined repair
facility of choice, take the
vehicle there, or have it towed
there. Specify to the facility
that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be
covered by the GM vehicle
warranty.
Insurance pays the bill for the
repair, but you must live with
the repair. Depending on your
policy limits, your insurance
company may initially value the
repair using aftermarket parts.
Discuss this with the repair
professional, and insist on
Genuine GM parts. Remember,
if the vehicle is leased, you
may be obligated to have the
vehicle repaired with Genuine
GM parts, even if your
insurance coverage does not
pay the full cost.
If another party's insurance
company is paying for the
repairs, you are not obligated
to accept a repair valuation
based on that insurance
company's collision policy
repair limits, as you have no
contractual limits with that
