number indicates the tire section
width in millimeters from sidewall
to sidewall.
(3) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size aspect
ratio is 60, as shown in item 3 of
the illustration, it would mean
that the tire's sidewall is
60 percent as high as it is wide.
(4) Construction Code

inside the tire pressing outward
on each square inch of the tire.
Air pressure is expressed in kPa
(kilopascal) or psi (pounds per
square inch).
Accessory Weight
:The combined
weight of optional accessories.
Some examples of optional accessories are automatic
transmission, power windows,
power seats, and air conditioning.

Appearance Care
Exterior Care
Locks
Locks are lubricated at the factory.
Use a de-icing agent only when
absolutely necessary, and have the
locks greased after using. See
Recommended Fluids and Lubricants
0334.
Washing the Vehicle
To preserve the vehicle's finish, wash
it often and out of direct sunlight.
Caution
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 warranty. Approved
cleaning products can be obtained
from your dealer. Follow all
manufacturer directions regarding
(Continued)
Caution (Continued)
correct product usage, necessary
safety precautions, and appropriate
disposal of any vehicle care
product.
Caution
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.
Caution
Do not power wash any component
under the hood that has this
e
symbol.
This could cause damage that
would not be covered by the vehicle
warranty. If using an automatic car wash, follow
the car wash instructions. The
windshield wiper and rear window
wiper, if equipped, must be off.
Remove any accessories that may be
damaged or interfere with the car
wash equipment.
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 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

care to thoroughly clean any areas
where mud and other debris can
collect.
Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate
the fluid. Contaminated fluid will
decrease the life of the transfer case
and/or axles and should be replaced.
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
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoidcorrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon and
attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface. See
“Finish Care”previously in
this section.
Interior Care
To prevent dirt particle abrasions,
regularly clean the vehicle's interior.
Immediately remove any soils.
Newspapers or dark garments can
transfer color to the vehicle’s interior.
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Using a mild soap
solution, immediately remove hand
lotions, sunscreen, and insect
repellent from all interior surfaces or
permanent damage may result. Use cleaners specifically designed for
the surfaces being cleaned to prevent
permanent damage. Apply all cleaners
directly to the cleaning cloth. Do not
spray cleaners on any switches or
controls. Remove cleaners quickly.
Before using cleaners, read and follow
all safety instructions on the label.
While cleaning the interior, open the
doors and windows to get proper
ventilation.
To prevent damage, do not clean the
interior using the following cleaners
or techniques:
.
Never use a razor or any other
sharp object to remove soil from
any interior surface.
. Never use a brush with stiff
bristles.
. Never rub any surface aggressively
or with too much pressure.
. Do not use laundry detergents or
dishwashing soaps with
degreasers. For liquid cleaners, use
approximately 20 drops per 3.8 L
(1 gal) of water. A concentrated
soap solution will create streaks

and attract dirt. Do not use
solutions that contain strong or
caustic soap.
. Do not heavily saturate the
upholstery when cleaning.
. Do not use solvents or cleaners
containing solvents.
Interior Glass
To clean, use a terry cloth fabric
dampened with water. Wipe droplets
left behind with a clean dry cloth.
If necessary, use a commercial glass
cleaner after cleaning with plain water.
Caution
To prevent scratching, never use
abrasive cleaners on automotive
glass. Abrasive cleaners or
aggressive cleaning may damage
the rear window defogger.
Cleaning the windshield with water
during the first three to six months of
ownership will reduce tendency to fog.
Speaker Covers
Vacuum around a speaker cover
gently, so that the speaker will not be
damaged. Clean spots with water and
mild soap.
Coated Moldings
Coated moldings should be cleaned.
. When lightly soiled, wipe with a
sponge or soft, lint-free cloth
dampened with water.
. When heavily soiled, use warm
soapy water.
Fabric/Carpet/Suede
Start by vacuuming the surface using
a soft brush attachment. If a rotating
vacuum brush attachment is being
used, only use it on the floor carpet.
Before cleaning, gently remove as
much of the soil as possible:
.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 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 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

VEHICLE CARE 321
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.
Instrument Panel, Leather, Vinyl,
Other Plastic Surfaces, Low
Gloss Paint Surfaces, and
Natural Open Pore Wood
Surfaces
Use a soft microfiber cloth dampened
with water to remove dust and loose
dirt. For a more thorough cleaning,
use a soft microfiber cloth dampened
with a mild soap solution.
Caution
Soaking or saturating leather,
especially perforated leather, as well
as other interior surfaces, may
cause permanent damage. Wipe
excess moisture from these surfaces
after cleaning and allow them to
dry naturally. Never use heat,
steam, or spot removers. Do not use
cleaners that contain silicone or
wax-based products. Cleaners
containing these solvents can
permanently change the appearance
and feel of leather or soft trim, and
are not recommended.Do not use cleaners that increase
gloss, especially on the instrument
panel. Reflected glare can decrease
visibility through the windshield
under certain conditions.
Caution
Use of air fresheners may cause
permanent damage to plastics and
painted surfaces. If an air freshener
comes in contact with any plastic
or painted surface in the vehicle,
blot immediately and clean with a
soft cloth dampened with a mild
soap solution. Damage caused by
air fresheners would not be covered
by the vehicle warranty.
Cargo Cover and
Convenience Net
If equipped, wash with warm water
and mild detergent. Do not use
chlorine bleach. Rinse with cold water,
and then dry completely.
