Appearance Care
Exterior Care
Washing the Vehicle
To preserve the vehicle's finish,
wash it often and out of direct
sunlight.
Notice: Do not use
petroleum-based, acidic,
or abrasive cleaning agents as
they can damage the vehicle's
paint, metal, or plastic parts.
If damage occurs, it would not be
covered by the vehicle's warranty.
Approved cleaning products can
be obtained from your dealer.
Follow all manufacturer
directions regarding correct
product usage, necessary safety
precautions, and appropriate
disposal of any vehicle care
product.

10-92 Vehicle Care
Notice:Avoid using
high-pressure washes closer than
30 cm (12 in) to the surface of the
vehicle. Use of power washers
exceeding 8,274 kPa (1,200 psi)
can result in damage or removal
of paint and decals.
Rinse the vehicle well, before
washing and after, to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.
Finish Care
Application of aftermarket clearcoat
sealant/wax materials is not
recommended. If painted surfaces
are damaged, see your dealer to
have the damage assessed and
repaired. Foreign materials such as
calcium chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals from
industrial chimneys, etc., can damage the vehicle's finish if they
remain on painted surfaces. Wash
the vehicle as soon as possible.
If necessary, use non-abrasive
cleaners that are marked safe for
painted surfaces to remove foreign
matter.
Occasional hand waxing or mild
polishing should be done to remove
residue from the paint finish. See
your dealer for approved cleaning
products.
Do not apply waxes or polishes to
uncoated plastic, vinyl, rubber,
decals, simulated wood, or flat paint
as damage can occur.
Notice:
Machine compounding or
aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.
To keep the paint finish looking new,
keep the vehicle garaged or
covered whenever possible. Protecting Exterior Bright Metal
Parts
Regularly clean bright metal parts
with water or chrome polish on
chrome or stainless steel trim,
if necessary.
For aluminum, never use auto or
chrome polish, steam, or caustic
soap to clean. A coating of wax,
rubbed to a high polish, is
recommended for all bright metal
parts.
Cleaning Exterior Lamps/
Lenses and Emblems
Use only lukewarm or cold water, a
soft cloth, and a car washing soap
to clean exterior lamps, lenses and
emblems. Follow instructions under
"Washing the Vehicle" in this
section.
Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.

Black plate (93,1)GMC Sierra Owner Manual - 2013 - crc - 8/14/12
Vehicle Care 10-93
Clean rubber 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
streaking.
Replace the wiper blades if they are
worn or damaged. Damage can be
caused by extreme dusty
conditions, sand, salt, heat, sun,
snow, and ice.
Weatherstrips
Apply silicone grease on
weatherstrips to make them last
longer, seal better, and not stick or
squeak. Lubricate weatherstrips
once a year. Black marks from
rubber material on painted surfaces
can be removed by rubbing with a
clean cloth. SeeRecommended
Fluids and Lubricants on
page 11‑12.
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Notice: Using petroleum-based
tire dressing products on the
vehicle may damage the paint
finish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
Wheels and Trim —Aluminum
or Chrome
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.
Notice: Chrome wheels and other
chrome trim may be damaged if
the vehicle is not washed after
driving on roads that have been
sprayed with magnesium,
calcium, or sodium chloride. These chlorides are used on
roads for conditions such as ice
and dust. Always wash the
chrome with soap and water after
exposure.
Notice:
To avoid surface damage,
do not use strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum or
chrome-plated wheels. Use only
approved cleaners. Also, never
drive a vehicle with aluminum or
chrome-plated wheels through an
automatic car wash that uses
silicone carbide tire cleaning
brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
Steering, Suspension, and
Chassis Components
Visually inspect the front and rear
suspension and steering system for
damaged, loose, or missing parts or
signs of wear. Inspect the power
steering for proper hook-up, binding,
leaks, cracks, chafing, etc. Visually

10-96 Vehicle Care
Fabric/Carpet/Suede
Start by vacuuming the surface
using a soft brush attachment. If a
rotating brush attachment is being
used during vacuuming, only use it
on the floor carpet. Before cleaning,
gently remove as much of the soil
as possible using one of the
following techniques:
.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 or club
soda. 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. Rotate the cleaning cloth
to a clean area frequently to
prevent forcing the soil in to 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 club
soda or 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.
Following the cleaning process, a
paper towel can be used to blot
excess moisture.
Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
For vehicles with high gloss
surfaces or vehicle displays, use a
microfiber cloth to wipe surfaces.
Before wiping the surface with the
microfiber cloth, use a soft bristle
brush to remove dirt that could
scratch the surface. Then use the
microfiber cloth by gently rubbing to
clean. 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.
Notice: Do not attach a device
with a suction cup to the display.
This may cause damage and
would not be covered by the
warranty.
