Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.) or if the front airbags have deployed. If there is any
question regarding belt or retractor condition, replace the
belt.
Airbag Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see you
authorized dealer. If the light stays on, flickers or comes
on while driving, have the system checked by an autho-
rized dealer. If there is a problem with the airbag light the
seatbelt light will flash.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for tread wear or uneven wear patterns.
Check for stones, nails, glass or other objects lodged in
the tread.
Inspect for tread cuts or sidewall cracks. Check wheel
nuts for tightness and tires for proper pressure.
Lights
Check the operation of all exterior lights. Check turn signal
and high beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.

place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
Because 4-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds.
Do not go faster than road conditions permit.
NOTE:Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or uneven tire
pressures, excessive vehicle loading, or cold tempera-
tures.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position see the information below:

highway driving. Dry hard surfaced roads.

POWER STEERING
Your power steering system will provide mechanical
steering capability if power assist is lost.
If for any reason the hydraulic pressure is interrupted, it
will still be possible to steer your vehicle. Under these
conditions you will experience a substantial increase in
steering effort.
TIRE SAFETY INFORMATION
Tire Markings
NOTE:
²P(Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter ªPº molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
234 STARTING AND OPERATING

Page 235 of 429

²European Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter9P9is absent from this tire
size designation. Example: 215/65R15 96H
²LT(Light Truck)-Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters ªLTº that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
²Temporary Spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter ªTº
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
²High Flotation tire sizing is based on U.S. design
standards and begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

ÐThe maximum speed corresponding to the Speed Symbol should only be achieved un-
der specified operating conditions. (ie. tire pressure, vehicle loading, road conditions and
posted speed limits).

Tire Loading and Tire Pressure
Tire Placard Location
NOTE:Some vehicles have a ªTire and Loading Infor-
mationº placard located on the driver's side ªBº pillar.
Tire and Loading Information Placard
This placard tells you important information about the,
1) number of people that can be carried in the vehicle
2) the total weight your vehicle can carry
3) the tire size designed for your vehicle
4) the cold tire inflation pressures for the front, rear
and spare tires.
STARTING AND OPERATING 239

Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire's load carrying capacity if you
adhere to the loading conditions, tire size and cold tire
inflation pressures specified on the Tire and Loading
Information placard and the Vehicle Loading section of
this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR's) for the front and rear
axles must not be exceeded. For further information on
GAWR's, vehicle loading and trailer towing, see the
Vehicle Loading section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement ªThe combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs.º on the Tire and Loading Information placard. Thecombined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement ªThe combined weight of occu-
pants and cargo should never exceed XXX poundsº on
your vehicle's placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX kilograms or XXX pounds.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if ªXXXº
amount equals 1400 lbs. and there will be five 150 lb.
passengers in your vehicle, the amount of available cargo
and luggage load capacity is 650 lb. (1400±750 (5 x 150) =
650 lb.)

WARNING!
Overloading of your tire is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRESÐGENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. SafetyÐ
WARNING!
Improperly inflated tires are dangerous and can
cause accidents.
²Under inflation increases tire flexing and can result
in tire failure.
²Over inflation reduces a tire's ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
²Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
²Over inflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting in
loss of vehicle control.
²Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
