® Mud and snow capability
"M/S" or "M+S" indicates the tire
has properties making it suitable
to drive in mud or
snow .~ indi­
cates a winter tire .
@ Composition of the tire cord
and m aterials
The number of plies indicates the
number of rubberized fabric lay­
ers in the tire. In general : the
more layers, the more weight a
tire can carry . Tire manufacturers
must also specify the materials
used in the tire . These include
steel, nylon, polyester and other
materials .
@Maximum permitted load
This number indicates the maxi­
mum load in kilograms and
pounds that the tire can carry .
@Uniform ti re quality grade
standards for treadwear,
traction and temperature resistance

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power steer­
ing, power brakes, power win ­
dows, power seats, radio, and
heater, to the extent that these
items are available as factory-in­
stalled equipment (whether in­
stalled or not) .
Aspect ratio
means the ratio of the height to
the width of the tire in percent .

ing response and better overall
handling on dry pavement .

Ma ximum (permissible }
inflation pres sure
means the maximum cold infla­
tion pressure to which a t ire may
be inflated . Also called "maxi ­
mum inflation pressure."
Normal occupant weight
means 150 l bs. (68 kilograms)
times the number of occupants
seated in the veh icle up to the to­
tal seating capacity of your vehi­
c le.
Occupant distribution
means distribution of occupants
in a vehicle.
Outer diameter
means the overall diameter of an
inflated new tire .
Overall width
means the linear distance be­
tween the exteriors of the side­
walls of an inflated tire, including
elevations due to labeling, deco­
rations, or protective bands or
ribs .
Wheels
Ply
means a layer of rubber-coated
parallel cords .
Production options weight
means the combined weight of
those installed regular production
options weighing over 5 lbs. (2.3 kg) in excess of those standard
items which they replace, not pre ­
viously considered in curb weight
or accessory weight, including heavy duty brakes , ride levelers ,
roof rack, heavy duty battery, and
special trim .
Radial ply tire
means a pneumatic tire in which
the ply cords that extend to the beads are laid at substantially 90
degrees to the centerline of the
tread .
Recommended inflation
pressure
see ~ page 286, Cold tire infla­
tion pressure .
Reinforced tire
means a tire designed to operate
at higher loads and at higher in­
flat ion pressures than the corre­
sponding standard tire. Rein ­
forced tires may be iden tified as

Wheels
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
l uggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
296
carried in the vehicle (including
the weight of a trailer hitch and the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as l uggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar

fig. 266.
_& WARNING ~
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.

u. co .... N
" N .... 0 0 :c ' & WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
-To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
-After washing the vehicle, the braking effect may be delayed due to moisture on the
brake rotors or ice in the winter . This in­
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.
@ Note
-If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
-To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
-
Care and cleaning
-To reduce the risk of damage, do not wash
the power top with a pressure washer.
-To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
-Matte finish painted vehicle components:
-To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
-Never use protective wax. It can destroy
the matte finish effect .
-Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved .
@ For the sake of the environment
Only wash the vehicle in facilities specially de­
signed for that purpose . This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
