Vehicle Care 10-103
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from
the upholstery and clean the glass
can be obtained from your dealer.
Do not clean the vehicle using:
.A knife or any other sharp object
to remove a soil from any interior
surface.
.A stiff brush. It can cause
damage to the interior surfaces.
.Heavy pressure or aggressive
rubbing with a cleaning cloth.
Use of heavy pressure can
damage the interior and does
not improve the effectiveness of
soil removal.
.Laundry detergents or
dishwashing soaps with
degreasers can leave residue
that streaks and attracts dirt. For
liquid cleaners, about 20 drops
per 3.78 L (1 gal) of water is a
good guide. Use only mild,
neutral-pH soaps.
.Too much cleaner that saturates
the upholstery.
.Cleaners that contain solvents
can damage the interior.
Fabric/Carpet
Use a vacuum cleaner with a
soft brush attachment frequently
to remove dust and loose dirt.
A canister vacuum with a beater bar
in the nozzle may only be used on
floor carpet and carpeted floor mats.
For any soil, always try to remove it
first with plain water or club soda.
Before cleaning, gently remove as
much of the soil as possible using
one of the following techniques:
.For liquids: gently blot the
remaining soil with a paper
towel. Allow the soil to absorb
into the paper towel until no
more can be removed.
.For solid dry soils: remove as
much as possible and then
vacuum.To clean:
1. Saturate a lint-free, clean white
cloth with water or club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled area until the cleaning cloth
remains clean.
5. If the soil is not completely removed, use a mild soap
solution and repeat the cleaning
process that was used with plain
water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. When a
commercial upholstery cleaner or
spot lifter is to be used, test a small
hidden area for colorfastness first.

10-104 Vehicle Care
If the locally cleaned area gives any
impression that a ring formation may
result, clean the entire surface.
After the cleaning process has been
completed, a paper towel can be
used to blot excess moisture from
the fabric or carpet.
Leather
Leather, and lighter colored leather
in particular, will need more frequent
cleaning to prevent the buildup of
dust, dirt, and colors transferred
from other items so that these do
not become permanent stains.
To remove dust, a soft cloth
dampened with water can be used.
If a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can be
used. Your dealer has a GM
approved leather cleaner available
that provides superior cleaning
performance when used regularly
on finished automotive leathers.
Allow the leather to dry naturally. Do
not use heat, steam, spot lifters or
spot removers, or shoe polish onleather. Many commercial leather
cleaners and coatings that are sold
to preserve and protect leather
may permanently change the
appearance and feel of the leather
and are not recommended. Do not
use silicone or wax-based products,
or those containing organic solvents
to clean the interior because they
can alter the appearance by
increasing the gloss in a
non-uniform manner.
Instrument Panel, Vinyl and
other Plastic Surfaces
A soft cloth dampened with water
may be used to remove dust.
If a more thorough cleaning is
necessary, a clean soft cloth
dampened with a mild soap solution
can be used to gently remove dust
and dirt. Never use spot lifters or
removers on plastic surfaces.
Many commercial cleaners and
coatings that are sold to preserve
and protect soft plastic surfaces
may permanently change the
appearance and feel of the interior
and are not recommended. Do
not use silicone or wax-based
products, or those containing
organic solvents to clean the
interior because they can alter the
appearance by increasing the gloss
in a non-uniform manner.
Some commercial products may
increase gloss on the instrument
panel. The increase in gloss may
cause annoying reflections in the
windshield and even make it difficult
to see through the windshield under
certain conditions.
Notice:
Air fresheners contain
solvents that may cause damage
to plastics and painted surfaces.
Follow the manufacturer ’s
instructions when using air
fresheners in the vehicle. If air
freshener comes in contact with
paint or a plastic surface, blot
immediately with a soft cloth.
Damage caused by using air
fresheners would not be covered
by the vehicle warranty.

Vehicle Care 10-105
Wood Panels
Use a clean cloth moistened in
warm, soapy water (use mild dish
washing soap). Dry the wood
immediately with a clean cloth.
Speaker Covers
Vacuum around a speaker cover
gently, so that the speaker will not
be damaged. Clean spots with just
water and mild soap.
Care of Safety Belts
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Floor Mats
{WARNING
If a floor mat is the wrong size or
is not properly installed, it can
interfere with the accelerator
pedal and/or brake pedal.
Interference with the pedals can
cause unintended acceleration
and/or increased stopping
distance which can cause a crash
and injury. Make sure the floor
mat does not interfere with the
accelerator or brake pedal.Use the following guidelines for
proper floor mat usage.
.The original equipment floor
mats were designed for the
vehicle. If the floor mats need
replacing, it is recommended
that GM certified floor mats be
purchased. Non-GM floor mats
may not fit properly and may
interfere with the accelerator or
brake pedal. Always check that
the floor mats do not interfere
with the pedals.
.Use the floor mat with the
correct side up. Do not turn
it over.
.Do not place anything on top of
the driver side floor mat.
.Use only a single floor mat on
the driver side.
.Do not place one floor mat on
top of another.
