Shifting Procedure - NV233 Transfer Case
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 for the previous position
will remain ON and the newly selected position indicator
light will continue to flash until all the requirements for
the selected position have been met. To retry a shift:
return the control knob back to the original position,
make certain all shift requirements have been met, wait
five (5) seconds and try the shift again.
2WD to 4HI or 4HI to 2WD
Rotate the 4WD Control Switch to the desired position.
Shifts between 2WD and 4HI can be done with the
vehicle stopped or in motion. With the vehicle in motion,
the transfer case will engage / disengage faster if you
momentarily release the accelerator pedal after turning
the control switch. If the vehicle is stopped, the ignition
key must be in the ON position with the engine either
RUNNING or OFF. This shift cannot be completed if the
key is in the accessory position.
NOTE:On vehicles equipped with Anti-Lock Brake
Systems, the 4x4 system will not allow shifts between
2WD/ 4HI if the rear wheels are spinning (no traction). In
this situation the selected position indicator light will
flash and the original position indicator light will remain
ON. At this time, reduce speed and stop spinning the
wheels to complete the shift. There may be a delay up to
10 seconds for the shift to complete after the wheels have
stopped spinning.

4HI to 4LO or 4LO to 4HI
NOTE:
When shifting into or out of 4LO 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 2-3
mph (3-5 km/h) or completely stopped. USE EITHER OF
THE FOLLOWING PROCEDURES:
Preferred Procedure
1. With engine RUNNING, slow vehicle to 2-3 mph (3-5
km/h).
2. Shift the transmission into NEUTRAL (depress clutch
on manual transmissions).
3. While still rolling, 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).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.
156 STARTING AND OPERATING
NV244 Transfer Case Operating Information /
Precautions
The NV244 is an electric shift transfer case and is
operated by the 4WD Control Switch, which is located on
the instrument panel.
The NV244 transfer case provides 4 mode positions -
Normal all wheel drive high range, 4 wheel drive high
range, 4 wheel drive 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 (AWD) at all times on any given
road surface, including dry hard surfaced roads. The
AWD 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 4HI position on dry hard surfaced roads.
This feature provides the safety, security, and conve-
nience of operating in all wheel drive at all times
regardless of road conditions.When additional traction is required, the 4HI and 4LO
positions can be used to lock the front and rear drive-
shafts together through the transfer case inter-axle differ-
ential 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 4HI and 4LO
positions are intended for loose, slippery road surfaces
only. Driving in the 4HI and 4LO positions on dry hard
surfaced roads may cause increased tire wear and dam-
age to the driveline components.
The transfer case Neutral (N) 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 (N) position is to be
used for recreational towing only. (See Recreational Tow-
ing section for specific procedures on shifting into and
out of Neutral (N).
Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
Four-Wheel-Drive Control Switch, found on your instru-
ment panel, and indicate the current and desired transfer

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.
The SERVICE 4WD 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 NV244 transfer
case is not equipped with a synchronizer and therefore
the front and rear driveshaft speeds must be equal for the

In this situation the selected position indicator light will
flash and the original position indicator light will remain
ON. At this time, reduce speed and stop spinning the
wheels to complete the shift. There may be a delay up to
10 seconds for the shift to complete after the wheels have
stopped spinning.
NOTE:Delayed shifting out of the 4HI position may be
experienced due to uneven tire wear, low tire pressure, or
excessive loading.

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
PARKING BRAKE
The parking brake should be applied whenever the
driver is not in the vehicle.
The foot operated parking brake is positioned below the
lower left corner of the instrument panel.
To apply the parking brake:Place your foot on the
parking brake pedal and push firmly downward as far as
the pedal will go. When the parking brake is applied and
the ignition is ON, the BRAKE light in the instrument
cluster will light.
NOTE:The BRAKE light in the instrument cluster
indicates only that the parking brake is appliedÐit does
not indicate the degree of application.
To release the parking brake:Pull the parking brake
release handle towards you. The BRAKE light in the
instrument cluster will go out when the parking brake is
disengaged.
To park on a hill:You must make sure that the parking
brake is fully applied and the gear shift lever is in PARK
(for an automatic transmission) or in REVERSE or FIRST
(for a manual transmission). You should apply the park-
ing brake before shifting to PARK; otherwise, the load on
the transmission locking mechanism may make it diffi-
cult to move the shift lever out of the Park position.
When parking on a hill, turn the front wheels:
²Towardthe curb on adownhillgrade.
²Awayfrom the curb on anuphillgrade.
