FOUR-WHEEL DRIVE OPERATION
NV 140 Transfer Case Operating
Information/Precautions — If Equipped
The NV 140 is a single speed (HI range only) transfer case
which provides convenient full-time four-wheel drive.
No driver interaction is required.
Proper operation of four-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 four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
NV 244 Generation II Transfer Case Operating
Information/Precautions — If Equipped
The NV 244 Generation II is an electric-shift transfer case
and is operated by the 4WD Control Switch, which is
located on the instrument panel.
The NV 244 Generation II transfer case provides four
mode positions - Normal four-wheel drive (4WD) high
range, four-wheel drive lock (4WD LOCK) range, four-
wheel drive low (4WD LOW) range, and NEUTRAL.
This transfer case is equipped with an inter-axle differ-
ential that allows driving the vehicle in the normal
all-wheel drive position (4WD) at all times on any given
road surface, including dry, hard-surfaced roads. The
4WD mode allows the front and rear wheels to rotate at
different speeds. This eliminates driveline binding and
component wear normally associated with driving the
vehicle in the 4WD LOCK position on dry, hard-surfaced

WARNING!
Always engage the parking brake when powering
down the vehicle if theSVC 4WD Warning 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 NV 244 Generation
II 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 4WD LOW, the engine
speed is approximately three times that of the 4WD or
4WD LOCK 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 four-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 four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

Shifting Procedure - NV 244 Generation II
Transfer Case
NOTE:
•The 4x4 system will not allow shifts between 4WD/
4WD LOCK if the rear wheels are spinning (no trac-
tion). In this situation, a position indicator light will
flash and the original position indicator light willremain on. At this time, reduce speed and stop spin-
ning the wheels to complete the shift. There may be a
delay up to 13 seconds for the shift to complete after
the wheels have stopped spinning.
•Delayed shifting out of the 4WD LOCK position may
be experienced due to uneven tire wear, low tire
pressure, or excessive loading.
•When shifting into, or out of 4WD LOW, some gear
noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) or completely stopped. USE EITHER
OF THE FOLLOWING PROCEDURES:
Preferred Shifting Procedure
1. With the engine running, slow the vehicle to 2 to
3 mph (3 to 5 km/h).
302 STARTING AND OPERATING
Page 305 of 498

2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the transfer case control
switch to the desired position.
4. After the position indicator light has stopped flashing,
shift the transmission back into gear.
Alternate Shifting Procedure
1. Bring the vehicle to a complete stop.
2. With the key ON and the engine either OFF or
running, shift the transmission into NEUTRAL.
3. Rotate the transfer case control switch to the desired
position.
4. After the position indicator light has stopped flashing,
shift the transmission back into gear.
NOTE:
•The ignition key must be ON for a shift to take placeand 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.
•If any of the requirements to select a new transfer case
position have not been met, the transfer case will not
shift. The indicator light will flash and the current
transfer case position will be maintained. To retry the
selection, turn the control knob back to the current
position, wait five seconds, and retry the shift.
DRIVING ON SLIPPERY SURFACES
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
STARTING AND OPERATING 303

2. Slow down if the road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front of you to avoid a collision in a sudden
stop.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or cross a road or a path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
304 STARTING AND OPERATING
Page 308 of 498

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
306 STARTING AND OPERATING
Page 312 of 498

The ABS conducts a low-speed self-test at about 12 mph
(20 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.
The ABS pump motor runs during the self-test at 12 mph
(20 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation, which is
normal.
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.
(Continued)
WARNING! (Continued)
•The ABS cannot prevent the natural laws of phys-
ics 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.
•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.
310 STARTING AND OPERATING
Page 313 of 498

CAUTION!
The ABS is subject to possible detrimental effects of
electronic interference caused by improperly in-
stalled aftermarket radios or telephones.
NOTE:During severe braking conditions, a pulsing
sensation may occur and a clicking noise will be heard.
This is normal, indicating that the ABS is functioning.
•Do not “ride” the brakes by resting your foot on the
pedal. This could overheat the brakes and result in
unpredictable braking action, longer stopping dis-
tances, or brake damage.
•When descending mountains or hills, repeated brak-
ing can cause brake fade with loss of braking control.
Avoid repeated heavy braking by downshifting the
transmission or locking out overdrive whenever pos-
sible.
•Engines may idle at higher speeds during warm-up,
which could cause rear wheels to spin and result in
loss of vehicle control. Be especially careful while
driving on slippery roads, in close-quarter maneuver-
ing, parking, or stopping.
•Do not drive too fast for road conditions, especially
when roads are wet or slushy. A wedge of water can
build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
•After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
