Tire Terminology and
Definitions
Air Pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight
This means the combined weight of
optional accessories. Some exam-
ples of optional accessories are
automatic transmission, 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 pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb Weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings
A code molded into the sidewall of a
tire signifying that the tire is in com-
pliance with the U.S. Department of
Transportation motor vehicle safety
standards. The DOT code includes
the Tire Identification Number (TIN),
an alphanumeric designator which
can also identify the tire manufactur-
er, production plant, brand and date
of production.

Maintenance
vehicle, pay particular attention to
the components under the fenders
and other areas that are hidden
from view. Do a thorough job; just
dampening the accumulated mud
rather than washing it away will
accelerate corrosion rather than
prevent it. Water under high pres-
sure and steam are particularly
effective in removing accumulated
mud and corrosive materials.
When cleaning lower door panels, rocker panels and frame members,
be sure that drain holes are kept
open so that moisture can escape
and not be trapped inside to accel-
erate corrosion.
Keep your garage dry
Don’t park your car in a damp, poor-
ly ventilated garage. This creates a
favorable environment for corrosion.
This is particularly true if you wash
your vehicle in the garage or drive it
into the garage when it is still wet or
covered with snow, ice or mud. Even
a heated garage can contribute to
corrosion unless it is well ventilated
so moisture is dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish
should be covered with "touch-up"
paint as soon as possible to reduce
the possibility of corrosion. If bare
metal is showing through, the atten-
tion of a qualified body and paint
shop is recommended.
Bird droppings are highly corrosive
and may damage painted surfaces in
just a few hours. Always remove bird
droppings as soon as possible.
Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from con-
tacting the interior parts because
they may cause damage or discol-
oration. If they do contact the interior
parts, wipe them off immediately.
See the instructions for the proper
way to clean vinyl.
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.
When cleaning leather prod-
ucts (steering wheel, seats
etc.), use neutral detergents
or low alcohol content solu-
tions. If you use high alcohol
content solutions or acid/
alkaline detergents, the color
of the leather may fade or the
surface may get stripped off.

Maintenance
Caring for the leather seats - Vacuum the seat periodically toremove dust and sand on the
seat. It will prevent abrasion or
damage of the leather and main-
tain its quality.
- Wipe the natural leather seat cover often with dry or soft cloth.
- Use of proper leather protective may prevent abrasion of the
cover and helps maintain the
color. Be sure to read the instruc-
tions and consult a specialist
when using leather coating or
protective agents.
- Light colored (beige, cream beige) leather is easily contami-
nated and the stain is noticeable.
Clean the seats frequently.
- Avoid wiping with wet cloth. It may cause the surface to crack. Cleaning the leather seats
- Remove all contaminationsinstantly. Refer to instructions
below for removal of each con-
taminant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminated spot.
Wipe off the cream with a wet
cloth and remove water with a dry
cloth.
- Beverages(coffee, soft drink, etc.) Apply a small amount of neutral
detergent and wipe until contami-
nations do not smear.
- Oil Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natu-
ral leather.
- Chewing gum Harden the gum with ice and
remove gradually.
Cleaning the seat belt webbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken
the seat belt.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid.
