Vehicle Care 10-107
High pressure car washes may
cause water to enter the vehicle.
Avoid using high pressure washes
closer than 30 cm (12 inches) 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.
Cleaning Exterior Lamps/
Lenses
Use only lukewarm or cold water, a
soft cloth and a car washing soap
to clean exterior lamps and lenses.
Follow instructions under“Washing
the Vehicle”.
Finish Care
Occasional waxing or mild polishing
of the vehicle by hand may be
necessary to remove residue from
the paint finish. Approved cleaning
products can be obtained from your
dealer.
If the vehicle has a basecoat/
clearcoat paint finish, the clearcoat
gives more depth and gloss to
the colored basecoat. Always
use waxes and polishes that are
non-abrasive and made for a
basecoat/clearcoat paint finish.
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. 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.
Exterior painted surfaces are
subject to aging, weather and
chemical fallout that can take their
toll over a period of years. To help
keep the paint finish looking new,
keep the vehicle garaged or
covered whenever possible.

10-108 Vehicle Care
Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Washing with water is all that
is usually needed. However, chrome
polish may be used on chrome or
stainless steel trim, if necessary.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap to
clean aluminum. A coating of
wax, rubbed to high polish, is
recommended for all bright metal
parts.Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean the 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.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper
removal
Aluminum or Chrome-Plated
Wheels and Trim
The vehicle may have either
aluminum or chrome-plated wheels.
Keep the wheels clean using a
soft clean cloth with mild soap
and water. Rinse with clean water.
After rinsing thoroughly, 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
vehicle's chrome with soap and
water after exposure.

Vehicle Care 10-109
Notice:Using strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum
or chrome-plated wheels, could
damage the surface of the
wheel(s). The repairs would
not be covered by the vehicle
warranty. Use only approved
cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is
similar to the painted surface of the
vehicle. Do not use strong soaps,
chemicals, abrasive polishes,
abrasive cleaners, cleaners with
acid, or abrasive cleaning brushes
on them because they could
damage the surface. Do not use
chrome polish on aluminum wheels. Notice:
Using chrome polish on
aluminum wheels could damage
the wheels. The repairs would
not be covered by the vehicle
warranty. Use chrome polish
on chrome wheels only.
Use chrome polish only on
chrome-plated wheels, but avoid
any painted surface of the wheel,
and buff off immediately after
application.
Notice: Driving the vehicle
through an automatic car wash
that has silicone carbide tire
cleaning brushes, could damage
the aluminum or chrome-plated
wheels. The repairs would not be
covered by the vehicle warranty.
Never drive a vehicle that has
aluminum or chrome-plated
wheels through an automatic car
wash that uses silicone carbide
tire cleaning brushes.Tires
To clean the tires, use a stiff brush
with tire cleaner.
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.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.

Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired right away. Bare metal will
corrode quickly and may develop
into major repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer. Larger
areas of finish damage can be
corrected in your dealer's body
and paint shop.
Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts
such as fuel lines, frame, floor pan,
and exhaust system even though
they have corrosion protection.
At least every spring, flush these
materials from the underbody
with plain water. Clean any areas
where mud and debris can collect.Dirt packed in close areas of the
frame should be loosened before
being flushed. Your dealer or an
underbody car washing system
can do this.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts
such as fuel lines, frame, floor pan,
and exhaust system even though
they have corrosion protection.
At least every spring, flush these
materials from the underbody
with plain water. Clean any areas
where mud and debris can collect.
Dirt packed in close areas of the
frame should be loosened before
being flushed. Your dealer or an
underbody car washing system
can do this.
Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can fall
upon and attack painted surfaces on
the vehicle. This damage can take
two forms: blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.
Although no defect in the paint job
causes this, we will repair, at no
charge to the owner, the surfaces
of new vehicles damaged by this
fallout condition within 12 months
or 20 000 km (12,000 miles) of
purchase, whichever occurs first.

Interior Care
The vehicle's interior will continue to
look its best if it is cleaned often.
Although not always visible,
dust and dirt can accumulate
on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic
surfaces. Regular vacuuming is
recommended to remove particles
from the upholstery. It is important to
keep the upholstery from becoming
and remaining heavily soiled. Soils
should be removed as quickly as
possible. The vehicle's interior may
experience extremes of heat that
could cause stains to set rapidly.Lighter colored interiors may require
more frequent cleaning. Use care
because newspapers and garments
that transfer color to home
furnishings may also transfer
color to the vehicle's interior.
When cleaning the vehicle's interior,
only use cleaners specifically
designed for the surfaces being
cleaned. Permanent damage may
result from using cleaners on
surfaces for which they were not
intended. Use glass cleaner only
on glass. Remove any accidental
over-spray from other surfaces
immediately. To prevent over-spray,
apply cleaner directly to the
cleaning cloth.Notice:
Using abrasive cleaners
when cleaning glass surfaces on
the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger. When
cleaning the glass on the vehicle,
use only a soft cloth and glass
cleaner.
Many cleaners contain solvents that
may become concentrated in the
vehicle's breathing space. Before
using cleaners, read and adhere to
all safety instructions on the label.
While cleaning the vehicle's interior,
maintain adequate ventilation by
opening the vehicle's doors and
windows.
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from
the vehicle's upholstery and clean
the vehicle's glass can be obtained
from your dealer.

10-112 Vehicle Care
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 vehicle's 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 gallon (3.78 L) of
water is a good guide. Use only
mild, neutral-pH soaps.
.Too much cleaner that saturates
the upholstery.
.Organic solvents such as
naptha, alcohol, etc. that can
damage the vehicle's 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.
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
A soft cloth dampened with water
can be used to remove dust.
If a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can be
used. Allow the leather to dry
naturally. Do not use heat to dry.
Never use steam to clean leather.
Never use spot lifters or spot
removers on leather. 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
vehicle's interior because they can
alter the appearance by increasing
the gloss in a non-uniform manner.
Never use shoe polish on leather.
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
vehicle's 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.
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.
