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 or 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
instrument cluster. If there are no indicator lights on or

flashing the transfer case position is all-wheel drive
(AWD). If an indicator light is on, the desired position
(4HI or 4LO) has been met.
If One or More Shift Requirements are not Met
1. An indicator light will flash until conditions are met.
2. The transfer case will 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 the Shifting Procedure for 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
SVC 4WDlight 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 NV244 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.
218 STARTING AND OPERATING
Page 219 of 408

When operating your vehicle in 4LO, the engine speed is
approximately three times that of the AWD 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.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
even if the transmission is in the Park (P) position.
The parking brake should always be applied when
the driver is not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position, see the information below:
AW D
Normal All Wheel Drive High Range - Employs inter-
axle differential. Allows front and rear wheels to rotate at
different speeds. All road surfaces.

Page 220 of 408

4HI
4 Wheel Drive High Range - Locks the transfer case
inter-axle differential. Forces front and rear wheels to
rotate at the same speed. Additional traction for loose or
slippery road surfaces only.
4LO
4 Wheel Drive Low Range - Low speed 4 wheel drive.
Locks the transfer case inter-axle differential. Forces the
front and rear wheels to rotate at the same speed.
Additional traction and maximum pulling power for
loose or slippery road surfaces only. Do not exceed 25
mph (40 km/h).
N
Neutral - Disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. See Recreational Towing for more infor-
mation.Shifting Procedure - NV244 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:
220 STARTING AND OPERATING
Page 221 of 408

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.
AWD to 4HI or 4HI to AWD
Rotate the 4WD Control Switch to the desired position.
Shifts between AWD 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 a Anti-Lock Brake
Systems, the 4x4 system will not allow shifts between
AWD/ 4HI if the rear wheels are spinning (no traction).
In this situation, an indicator light will flash until condi-
tions are met. 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.
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).
STARTING AND OPERATING 221

2. Shift the transmission into NEUTRAL (depress clutch
on manual transmissions).
3. Ensure ignition key is in the ON position with the
engine either RUNNING or OFF. 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.

LIMITED-SLIP REAR AXLE DIFFERENTIAL— 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.

PARKING BRAKE
The foot operated parking brake is positioned below the
lower left corner of the instrument panel. To release the
parking brake, pull the parking brake release handle.
Be sure the parking brake is firmly set when parked and
the gear-shift lever is in the PARK position. When
parking on a hill you should apply the parking brake before placing the gear shift lever in PARK; otherwise the
load on the transmission locking mechanism may make it
difficult to move the selector 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.
