FOUR-WHEEL DRIVE OPERATION
NV 140 Transfer Case Operating
Information/Precautions ± If Equipped
The NV 140 is a single speed (4 HI range only) transfer
case which provides convenient full-time 4-wheel drive.
No driver interaction is required. This transfer case
divides engine torque almost evenly with 48 percent of
engine torque to the front axle and 52 percent of engine
torque to the rear axle.
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.4WD
Normal 4-Wheel Drive High Range - Employs inter-axle
differential. Allows front and rear wheels to rotate at
different speeds. All road surfaces.
NV 244 Generation II Transfer Case Operating
Information / Precautions
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 4-wheel drive (4WD) high
range, 4-wheel-drive lock (4WD LOCK), 4-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
280 STARTING AND OPERATING

WARNING!
Always engage the parking brake when powering
down the vehicle if the(SVC 4WD(light is illumi-
nated. 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 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.
282 STARTING AND OPERATING

4WD LOW
The 4-Wheel Drive Low (4WD LOW) Range provides
low speed 4-wheel drive. It locks the front and rear
driveshafts together, forcing the front and rear wheels to
rotate at the same speed. This range provides additional
traction and maximum pulling power for loose or slip-
pery road surfaces only. Do not exceed 25 mph (40
km/h).
N
The NEUTRAL ranged disengages both the front and
rear driveshafts from the powertrain. NEUTRAL is used
for flat towing behind another vehicle. Refer to ªRecre-
ational Towingº in Section 5.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
traction). In this situation, a position indicator light will
flash and the original position indicator light will remain
on. At this time, reduce speed and stop spinning the
284 STARTING AND OPERATING

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.
NOTE:Delayed shifting out of the 4WD LOCK position
may be experienced due to uneven tire wear, low tire
pressure, or excessive loading.
NOTE: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 Procedure
1. With the engine running, slow the vehicle to 2 to 3
mph (3 to 5 km/h).
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 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
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.

NOTE: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.
2. Slow down if 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 to avoid a collision in a sudden stop.
DRIVING THROUGH WATER
Driving through water more than a few inches/
millimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
286 STARTING AND OPERATING

CAUTION!
²Driving through standing water may cause dam-
age to your vehicle's drivetrain components. Al-
ways inspect your vehicle's fluids (i.e., engine oil,
transmission, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not con-
tinue to operate the vehicle if any fluid appears
contaminated, as this may result in further dam-
age. Such damage is not covered by the New
Vehicle Limited Warranty.
²Getting water inside your vehicle's engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
²Driving through standing water limits your vehi-
cle's traction capabilities. Do not exceed 5 mph (8
km/h) when driving through standing water.
²Driving 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.
²Getting water inside your vehicle's engine can
cause it to lock up and stall out, and leave you
stranded.
²Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
288 STARTING AND OPERATING

WARNING!
²Always fully apply the parking brake when leav-
ing your vehicle, or the vehicle may roll and cause
damage or injury. Also be certain to leave an
automatic transmission in Park. 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.
²Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Don't leave the keys in
the ignition. A child could operate power win-
dows, 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 systems lose 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.
Four-Wheel Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (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 lock-up and help avoid skidding on slippery
290 STARTING AND OPERATING

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 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.At the instant one of the wheels is about to lock up, a
slight pulsation can be felt in the brake pedal, indicating
that the ABS is in the regulating mode. Keep firm and
steady pressure on the brake pedal while experiencing
the pulsation. Continuous, steady brake pedal pressure
results in optimal braking power while maintaining the
ability to steer the vehicle. In the case of an emergency
brake maneuver, keep continuous full pressure on the
brake pedal. In this manner only can the ABS be most
effective. On slippery road surfaces, the ABS will respond
even with light brake pedal pressure because of the
increased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra care
while driving.
