A WARNING ,~
Heavy loads will influence the way your ve­
hicle handles. To help reduce the r isk of a
loss of control leading to ser ious personal
injury:
-Always keep in m ind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
vehicle handling:
- Always distr ibute the load as even ly as
possible.
- Place heavy objects as far forward in
the luggage compartment as poss ible.
- Never exceed the Gross Ax le Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left do or jamb. Exceeding per­
missib le we ight standards can cause the
vehicle to s lide and handle differently.
- Please observe information on safe driv­
ing co
page 126.
A WARNING
To help prevent poisonous exhaust gas
from be ing drawn into the veh icle, always
keep the rea r lid closed while dr iving.
- Never transport objects larger than those fitting completely into the luggage
area because the rear lid cannot be fully
cl osed.
- If you absolutely must drive w ith the rear
l id ope n, observe the follow ing notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power top,
- Open all air ou tlets in the instrument
panel,
- Sw itch off the air recircu lation,
- Set the fresh ai r fan to the h ighest
speed.
A WARNING
Alw ays m ake s ure th at the doors, all win­
dows, the power top an d the re ar lid are
securely closed and locked to reduce th e

risk of injury when the vehicle is not being
used .
- After closing the rear lid, always make
sure that it is properly closed and loc ked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child cou ld craw l into the vehicle thro ugh
the luggage compartment and close the
rea r lid becoming t rapped and unable to
get out. Being trapped in a vehicle can
lead to serious pe rsonal inj ury.
- Never let ch ildren play in or around the
veh icle.
- Never let passengers ride in the luggage
compa rtment. Vehicle occupants must
always be properly restra ined in one of
the vehicle's seating pos it ions.

bel is located on the driver's side B-pilla r.

The luggage compartment is equipped with
four tie-downs to secure luggage and other
items .

is made of steel wires, wrapped
or reinforced by ply cords and
that is shaped to fit the rim.
Bead separation
means a breakdown of the bond

Cord
means the strands forming the
plies in the tire .
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manu­

ed size that has not been driven
for more than a couple of miles (kilometers) at low speeds in
the three hour period before
the tire pressure is measured or
adjusted.
Curb weight
means the weight of a motor
vehicle with standard equip­
ment including the maximum
capacity of fuel, oil, and cool­
ant, air conditioning and addi­
tional weight of optional equip­
ment.
Tires and wheels 231
Extra load tire
means a tire design to operate
at higher loads and at higher inflation pressures than the
corresponding standard tire. Extra load tires may be identi­
fied as "XL", "xl", "EXTRA
LOAD", or "RF" on the sidewall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capaci­
ty of a single axle system,
measured at the tire-ground in­
terfaces.
Gross Vehicle Weight Rating ("GVWR")
means the maximum total
loaded weight of the vehicle.
Groove
means the space between two
adjacent tread ribs.
Load rating (code)
means the maximum load that
a tire is rated to carry for a giv­
en inflation pressure. You may
not find this information on all
tires because it is not required by law.

Ma ximum load rating
means the load rating for a tire
at the maximum permissible in­
flation pressure for that tire.
Maximum loaded vehicle
weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options weight
Maximum (permissible)
inflation pressure
means the maximum cold infla­
tion pressure to which a tire
may be inflated. Also called
"maximum inflation pressure."
Normal occupant weight
means 150 lbs. (68 k ilograms)
times the number of occupants seated in the vehicle up to the
total seat ing capac ity of your
vehicle.
Occupant distribution
means distribution of occu ­
pants in a vehicle .

tween the ex teriors of the side­
