ments, refer to the9Shifting Procedure9for your transfer
case, located in this section of the owner's manual.
The ªSERVICE 4WDº warning light monitors the electric
shift 4WD system. If this light remains on after engine
start up or illuminates during driving, it means that the
4WD system is not functioning properly and that service
is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the(Service 4WD(light is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The NV233 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.
When operating your vehicle in 4LO, the engine speed is
approximately three times that of the 2WD or 4HI
positions at a given road speed. Take care not to over-
speed 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 in tire size 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.

case selection. When you select a different transfer case
position, the indicator lights will do the following:
If All Shift Requirements are Met
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until the
transfer case completes the shift.
3. When the shift is complete, the indicator light for the
selected position will stop flashing and remain ON.
If One or More Shift Requirements are not Met
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will flash.
3. The transfer casewill notshift.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the control knob back to the current position, wait five (5)seconds, and retry selection. To find the shift require-
ments, refer to the9Shifting Procedure9for your transfer
case, located in this section of the owner's manual.

Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the key ON and the engine either OFF or
RUNNING, shift the transmission into NEUTRAL (de-
press clutch on manual transmissions).
3. Rotate the transfer case control switch to the desired
position.
4. After the desired position indicator light is ON (not
flashing), shift transmission back into gear (release clutch
on manual transmissions).
NOTE:If steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the shift or
if they no longer are being met while the shift attempt is
in process, then the desired position indicator light will
flash continuously while the original position indicator
light is ON, until all requirements have been met.
NOTE:The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key is not ON then the shift will not take place and
no position indicator lights will be on or flashing.
LIMITED-SLIP DIFFERENTIAL Ð IF EQUIPPED
The limited-slip differential provides additional traction
on snow, ice, mud, sand and gravel. It improves traction
when there is a difference between the characteristics of
the surface under the right and left rear wheels. During
normal driving and cornering, the limited-slip unit is
similar to a conventional differential. But on a slippery
surface, the differential delivers more of the driving effort
to the wheel having the better traction.
WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear
wheel remaining on the ground and cause you to
lose control of the vehicle.
Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.
162 STARTING AND OPERATING

WARNING!
²Always fully apply the parking brake when leav-
ing your vehicle, or vehicle may roll and cause
damage or injury. Also be certain to leave an
automatic transmission in Park, a manual trans-
mission in Reverse or first gear. Failure to do so
may cause the vehicle to roll and cause damage or
injury.
²Be sure the parking brake is fully disengaged
before driving. Failure to do so can lead to brake
failure and an accident.
²Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don't leave the key in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
BRAKE SYSTEM
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be significantly increased over that
required with the power system operating.
If either the front or rear hydraulic system loses normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident by
increased pedal travel during application, greater pedal
force required to slow or stop, and activation of the Brake
Warning light and the ABS light during brake use.
Rear Wheel Anti-Lock Brake System
This Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically controls the opera-
tion of the rear brakes to prevent rear wheel lockup.
The system remains operational in the four-wheel drive
mode. The level of performance is reduced when the
front brakes are locked up. This will cause the rear brakes
to lock-up through the drivetrain, which may reduce the
effectiveness of the anti-lock system.
164 STARTING AND OPERATING

During severe braking conditions, particularly with
changing road surfaces, such as ice to concrete, a slight
drop or minor pulsation may be felt in the brake pedal.
WARNING!
Both Anti-Lock Brake Systems contain sophisticated
electronic equipment. It may be susceptible to inter-
ference caused by improperly installed or high out-
put radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capabil-
ity. Installation of such equipment should be done
by qualified professionals.
Four-Wheel Anti-Lock Brake System Ð If
Equipped
This 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.The system's pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The Anti-Lock Brake System includes an amber ABS
warning light. When the light is illuminated, the Anti-
Lock Brake System is not functioning. The system reverts
to standard non-anti-lock brakes. Turning the ignition
OFF and ON again may reset the Anti-Lock Brake System
if the fault detected was only momentary.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.

WARNING!
²Remove the fuel tank filler tube cap (gas cap)
slowly to prevent fuel spray from the filler neck
which may cause injury.
²The volatility of some gasolines may cause a
buildup of pressure in the fuel tank that may
increase while you drive. This pressure can result
in a spray of gasoline and/or vapors when the cap
is removed from a hot vehicle. Removing the cap
slowly allows the pressure to vent and prevents
fuel spray.
²Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
²Never add fuel to the vehicle when the engine is
running.
Fuel Tank Filler Tube
NOTE:
On some models, the fuel tank filler tube has a
restricting door about 2 inches (50 mm) down from the
opening. If fuel is poured from a portable container, the
container should have a flexible nozzle long enough to
force open the restricting door.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
NOTE:When the fuel nozzle ªclicksº or shuts off, the
fuel tank is full.
NOTE:Tighten the gas cap until you hear a ªclickingº
sound. This is an indication that the gas cap is properly
tightened.
The Check Engine light will come on if the gas cap is
not properly secured. Make sure that the gas cap is
tightened each time the vehicle is refueled.

WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system, and could result
in loss of warranty coverage.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor orsome light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²When pulling a heavy load or driving a fully loaded
vehicle when the humidity is low and the temperature
is high, use a premium unleaded fuel to help prevent
spark knock. If spark knock persists, lighten the load,
or engine piston damage may result.
²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer and may not be
covered under the New Vehicle Warranty.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

of the trailer lights and assure their proper functioning, a
heavy duty turn signal flasher can be installed as a
separate equipment item by your dealer.
WARNING!
The direct connection of hydraulic brake lines from
vehicle brake system to trailer system is not accept-
able. The extra load may cause brake failure and you
may be injured.
Heavy trailer towing also may require breakaway electric
trailer brakes, anti-sway devices or equalizing hitches for
safe operation. Such devices are commonly required by
state law.
For all trailer tow or heavy-duty applications it is
strongly recommended that the factory fill rear axle
lubricant be replaced with an SAE 75W-140 synthetic
gear lubricant. MopartSynthetic Gear Lubricant is of
this type.
Trailer Tow Wiring
The Trailer Tow Package includes a wiring harness
located at the rear underbody of the vehicle.
NOTE:Connect trailer lighting and brakes using fac-
tory harnesses only. Do not cut or splice wiring to the
brake circuits.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
