THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

Airbag Warning Light
The airbag warning light should come on, and remain on,
for six to eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not lit during
starting, see your authorized dealer. If the light stays on,
flickers or comes on while driving, have the system
checked by an authorized dealer. If there is a problem
with the airbag warning light, the seat belt 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.

15. Shift Lever Indicator (Automatic Transmission
Only)
This display indicator shows the automatic transmission
shift lever selection.
NOTE:You must apply the brake before shifting from
PARK.
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. U.S. federal regulations require that upon
transfer of vehicle ownership, the seller certify to the
purchaser the correct mileage that the vehicle has been
driven. Therefore, if the odometer reading is changed
during repair or replacement, be sure to keep a record of
the reading before and after the service so that the correct
mileage can be determined.
The two trip odometers show individual trip mileage. To
switch from odometer to trip odometers, press and
release the Trip Odometer button. To reset a trip odometer, display the desired trip odom-
eter to be reset then push and hold the button until the
display resets (approximately two seconds).
Vehicle Warning Messages
When the appropriate conditions exist, messages such as
“door” (indicates that a door(s) may be ajar), “hood” (if
the hood is open or ajar, on vehicles with remote start),
“gASCAP” (indicates that your gas cap is possibly loose
or damaged), “Low Tire” (indicates low tire pressure),
CHANgE OIL” (indicates that the engine oil should be
changed), “LoWASH” (low washer fluid), and “noFUSE”
(indicates that the IOD fuse is removed from the Inte-
grated Power Module), will display in the odometer.
NOTE:
There is also an engine hour function. This
indicates the total number of hours the engine has been
running. To display the engine hours perform the follow-
ing: Place the ignition in RUN, but do not start the
engine. With the odometer value displayed, hold the trip

at a given road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
Proper operation of 4-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference will adversely affect shifting and can
cause damage to the transfer case.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The transfer case is not
equipped with a synchronizer and therefore the front and
rear driveshaft speeds must be equal for the shift to take
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 position without first fully engaging the
parking brake. The transfer case NEUTRAL 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.

Four-Wheel Anti-Lock Brake System
WARNING!
•Anti-Lock Brake Systems (ABS) contain sophisti-
cated electronic equipment. It may be susceptible
to interference caused by improperly installed or
high output radio transmitting equipment. This
interference can cause possible loss of anti-lock
braking capability. Installation of such equipment
should be performed by qualified professionals.
•ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.(Continued)
WARNING! (Continued)
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
This ABS is designed to aid the driver in maintaining
vehicle control under adverse braking conditions. The
system operates with a separate computer to modulate
hydraulic pressure to prevent wheel lockup and help
avoid skidding on slippery surfaces.

TIRE SAFETY INFORMATION
Tire MarkingsNOTE:
•P (Passenger) - Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•European-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 letterPis absent from this tire
size designation. Example: 215/65R15 96H.
•LT (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 “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary spare tires are high-pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”

Tire Loading and Tire Pressure
Tire Placard Location
NOTE:The proper cold tire inflation pressure is listed
on the driver’s side B-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) total weight your vehicle can carry
3) tire size designed for your vehicle
4) cold tire inflation pressures for the front, rear, and
spare tires.
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 in the “Vehicle Loading” section
of this manual.
NOTE: Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in this section.
