How The Airbag System Works
•
The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC may modify the rate of inflation based on the occupant size
provided by the Occupant Classification Module. The
ORC will not detect roll over, or rear impacts.
The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, and knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.
Also, the ORC turns on the AIRBAG warning light
(located in the instrument cluster) and PAD indicator
light (located in the front passenger grab handle) for 6 to
8 seconds for a self-check when the ignition is first turned
on. After the self-check, the AIRBAG warning light will
turn off. The PAD indicator light will function normally
(Refer to “Passenger Airbag Disable (PAD) Indicator
Light” in this section). If the ORC detects a malfunction
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

in any part of the system, it turns on the AIRBAG
warning light either momentarily or continuously. A
single chime will sound if the light comes on again after
initial start up.
WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•The Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to inflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the
upper right side of the instrument panel separate and
fold out of the way as the bags inflate to their full size.
The bags fully inflate in about 50–70 milliseconds. This
is about half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver’s front airbag gas is vented through vent
holes in the sides of the airbag. The passenger’s front
airbag gas is vented through vent holes in the sides of
the airbag. In this way the airbags do not interfere with
your control of the vehicle.•The
Side Impact SRS Window Bags are designed to
activate only in certain side collisions. When the ORC
(with side impact option) detects a collision requiring
the window bags to inflate, it signals the inflators on

INSTRUMENT CLUSTER DESCRIPTION
1. Tachometer
Indicates the permissible engine revolutions-per-minute
for each gear range. Before reaching the red area, ease up
on the accelerator to prevent engine damage.
2. Turn Signal Indicator Light The arrows will flash in unison with the exterior
turn signals, when using the multi-function control
lever. A chime will sound if the turn signals are left on
continuously for 2 miles (3 km) until they are deacti-
vated.
3. High Beam Indicator Light This light shows that the headlights are on high
beam. Pull the multi-function control lever to-
wards the steering wheel to switch the headlights from
high to low beam. 4. Speedometer
Indicates vehicle speed.
5. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and

CAUTION!
•Do not attempt to make a shift while only the
front or rear wheels are spinning. The Command-
Trac transfer case is not equipped with a synchro-
nizer 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.
•When operating your vehicle in 4L, the engine
speed is approximately three times that of the 2H
or 4H positions 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.

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.
WARNING!
•Because 4-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit.
•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 drive-
shafts 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.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position see the information below:
2WD
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.
4 PART TIME
Part Time 4–Wheel Drive High Range - Locks the transfer
case inter-axle differential. Forces the front and rear
wheels to rotate at the same speed. Additional traction
for loose, slippery road surfaces only.
4 FULL TIME
Full Time 4-Wheel Drive High Range - Employs an
inter-axle differential. This allows front and rear wheels
to rotate at different speeds, on all road surfaces.
240 STARTING AND OPERATING

Be sure the parking brake is fully disengaged before
driving. Failure to do so can lead to brake failure.
NOTE: Parking brake adjustment and maintenance
should be performed by your authorized dealer.
ANTI-LOCK BRAKE SYSTEM — IF EQUIPPED
The Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lock-up and help avoid skidding on slippery surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-
test at about 12 mph (20 km/h). If for any reason, your
foot is on the brake when the vehicle reaches 12 mph (20
km/h), this check will be delayed until 25 mph (40
km/h).
The Anti-Lock Brake System pump motor runs during
the self-test and during an ABS stop to provide the
regulated hydraulic pressure. The motor pump makes a
low humming noise during operation, this is normal.

WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspension
components. You could lose control and have an
accident resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment and Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your autho-
rized dealer for proper diagnosis.

The system will consist of tire pressure monitoring
sensors attached to each wheel through the valve stem
mounting hole, a central receiver module and a “Tire
Pressure Monitoring Telltale Light.” A sensor is located in
the spare wheel if the vehicle is equipped with a match-
ing full size spare wheel and tire assembly.
NOTE: For vehicles with optional wheel/tire sizes and
significantly different tire placard pressures, the placard
pressure value and the low-pressure threshold value is
re-programmable at your authorized dealer to accommo-
date the customer selected wheel/tire combinations rec-
ommended by DaimlerChrysler Corporation.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the wheel rim sensor.
NOTE:
•The TPMS can inform the driver of a low tire pressure
condition.
•The TPMS is not intended to replace normal tire care
and maintenance, nor to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
