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-surfacedroads. This feature provides the safety, security, and
convenience of operating in all-wheel drive at all times
regardless of road conditions.
When additional traction is required, the 4WD LOCK
and 4WD LOW positions can be used to lock the front
and rear driveshafts together, through the transfer case
inter-axle differential, and force the front and rear wheels
to rotate at the same speed. This is accomplished by
rotating the 4WD Control Switch to these positions. The
4WD LOCK and 4WD LOW positions are intended for
loose, slippery road surfaces only. Driving in the 4WD
LOCK and 4WD LOW positions on dry, hard-surfaced
roads may cause increased tire wear and damage to the
driveline components.
The transfer case NEUTRAL position is selected by
depressing the recessed button located on the lower left
hand corner of the 4WD Control Switch.

NOTE:The transfer case NEUTRAL position is to be
used for recreational towing only. Refer to ªRecreational
Towingº in this section for specific procedures on shifting
into and out of NEUTRAL.
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster. If there are no indicator lights on or
flashing, the transfer case position is four-wheel drive
(4WD) and indicates the current and desired transfer case
selection (4WD,4WD LOCK).
The ªSVC 4WD Warning Lightº 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. See your authorized dealer for service.
WARNING!
Always engage the parking brake when powering
down the vehicle if the(SVC 4WD Warning Lightº 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.
286 STARTING AND OPERATING

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.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 allows 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, refer to the following infor-
mation:
4WD
This range allows front and rear wheels to rotate at
different speeds on all road surfaces.
STARTING AND OPERATING 287

4WD LOCK
This range locks the transfer case inter-axle differential,
forcing the front and rear wheels to rotate at the same
speed. Additional traction for loose, slippery road sur-
faces only.
4WD LOW
This range provides low speed four-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 slippery road surfaces only. Do not
exceed 25 mph (40 km/h).
N
This range disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. Refer to ªRecreational Towingº in this
section.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
288 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 Shifting 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 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
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.

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/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. 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.
292 STARTING AND OPERATING

Be sure the parking brake is firmly set when parked and
the shift lever is in PARK position. When parking on a
hill, you should apply the parking brake before placing
the shift lever in PARK; otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK.NOTE:The instrument cluster brake warning light
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should be applied whenever the
driver is not in the vehicle.
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.

WARNING! (Continued)
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.
ANTI-LOCK BRAKE SYSTEM
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
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.
