(B) Tire Width:The three‐digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(C) 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 C of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A
letter code is used to indicate
the type of ply construction in
the tire. The letter R means
radial ply construction; the
letter D means diagonal or
bias ply construction; and the
letter B means belted‐bias ply
construction.
(E) Rim Diameter
:Diameter of
the wheel in inches. (F) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount
of air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in psi (pounds per
square inch) or kPa (kilopascal).
Accessory Weight
:The
combined weight of optional
accessories. Some examples
of optional accessories are,
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning. Aspect Ratio
:The relationship
of a tire's height to its width.
Belt
:A rubber coated layer of
cords that is located between
the plies and the tread. Cords
may be made from steel or
other reinforcing materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire
:A pneumatic
tire in which the plies are laid
at alternate angles less than
90 degrees to the centerline
of the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. See Tire Pressure
on page 10‑54.

If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 6‑4.
See If a Tire Goes Flat on
page 10‑70 for other important
safety warnings.
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑79.
2. Unwrap the sealant/air hose (F) and the power plug (G).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise. 5. Attach the sealant/air hose (F)
onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (G) into the accessory power outlet in the

sealant and air into the tire.
The pressure gauge (D) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only.
10. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (D). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑54.

Interior Care
The interior will continue to look
its best if it is cleaned often.
Dust and dirt can accumulate
on the upholstery and cause
damage to the carpet, fabric,
leather, and plastic surfaces.
Stains should be removed quickly
as extreme heat could cause
them to set rapidly.
Lighter colored interiors may
require more frequent cleaning.
Newspapers and garments that
can transfer color to home
furnishings can also transfer
color to the interior.
Remove dust from small buttons
and knobs with a small brush with
soft bristles.
Your dealer has products for
cleaning the interior. When
cleaning the interior, only use
cleaners specifically designed
for the surfaces that are beingcleaned. Permanent damage
can result from using cleaners
on surfaces for which they were
not intended. Apply the cleaner
directly to the cleaning cloth to
prevent over-spray. Remove any
accidental over-spray from other
surfaces immediately.
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.
Cleaners can contain solvents
that can become concentrated
in the interior. Before using
cleaners, read and adhere to all
safety instructions on the label.
While cleaning the interior,
maintain adequate ventilation by
opening the doors and windows. Do not clean the interior using the
following cleaners or techniques:.Never use a knife or any other
sharp object to remove a soil
from any interior surface.
.Never use a stiff brush. It can
cause damage.
.Never apply heavy pressure or
rub aggressively with a cleaning
cloth. Use of heavy pressure can
damage the interior and does
not improve the effectiveness
of soil removal.
.Avoid laundry detergents
or dishwashing soaps with
degreasers. Using too much
soap will leave a residue that
leaves 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.
.Do not heavily saturate the
upholstery while cleaning.
.Cleaners that contain solvents
can damage the interior.

first). More frequent replacement
may be needed if you drive
in areas with heavy traffic,
areas with poor air quality,
or areas with high dust levels.
Replacement may also be
needed if you notice reduced
air flow, windows fogging up,
or odors. Your dealer can help
you determine when it is the
right time to replace the filter. First Engine Oil Change After
Every 80 000 km/50,000 Miles
.Engine air cleaner filter
replacement. See
Engine Air
Cleaner/Filter on page 10‑15.
.Automatic transmission fluid
change (severe service)
for vehicles mainly driven
in heavy city traffic in hot
weather, in hilly or mountainous
terrain, when frequently towing
a trailer, or used for taxi,
police, or delivery service.
See Automatic Transmission
Fluid on page 10‑15.
.All‐wheel drive only: Transfer
case fluid change (severe
service) for vehicles mainly
driven when frequently towing
a trailer, or used for taxi, police,
or delivery service. Check
vent hose at transfer case for
kinks and proper installation.
Check to be sure vent hose is
unobstructed, clear, and free of
debris. During any maintenance,
if a power washer is used to
clean mud and dirt from the
underbody, care should be taken
to not directly spray the transfer
case output seals. High pressure
water can overcome the seals
and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should be
replaced.
