FOUR-WHEEL DRIVE OPERATION
NV233/243 GII Transfer Case Operating
Information/Precautions
The NV233/243 is an electric shift transfer case and is
operated by the 4WD Control Switch (Transfer Case
Switch), which is located on the instrument panel.
The NV233/243 transfer case provides 4 mode positions:
2 (rear) wheel drive high range, 4 wheel drive high range,
4 wheel drive low range, and neutral.
The NV233/243 transfer case is designed to be driven in
the 2 wheel drive position (2WD) for normal street and
highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4WD LOCK and 4WD LOW positions can be used to lock
the front and rear driveshafts together and force the front
and rear wheels to rotate at the same speed. This is
accomplished by rotating the 4WD Control Switch to thedesired position - see Shifting Procedure section for
specific shifting instructions. The 4WD LOCK and 4WD
LOW positions are designed for loose or slippery road
surfaces only. Driving in the 4WD LOCK and 4WD LOW
positions on dry hard-surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents.
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 is no indicator light on or
flashing, the transfer case position is two-wheel drive
STARTING AND OPERATING 199

(2WD). If the indicator light is on, the desired position
(4WD LOCK and 4WD LOW) has been obtained.
If One or More Shift Requirements are not Met:
1. An indicator light will flash.
2. 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 theShifting Procedurefor your transfer
case, located in this section of the owner’s manual.
The “SVC 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 theSVC 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 NV233/243 trans-
fer case is not equipped with a synchronizer and there-
fore 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 trans-
fer case.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or
200 STARTING AND OPERATING

4WD LOCK
4 Wheel Drive Lock (4WD LOCK) Range - Locks the front
and rear driveshafts together. Forces the front and rear
wheels to rotate at the same speed. Additional traction
for loose or slippery road surfaces only.
4WD LOW
4 Wheel Drive Low (4WD LOW) Range - Low speed 4
wheel drive. Locks the front and rear driveshafts to-
gether. 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 - NV233/243 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 indica-
tor light will continue to flash until all the requirements
for the selected position have been met. To retry a shift:
202 STARTING AND OPERATING

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 4WD LOCK or 4WD LOCK to 2WD
Rotate the 4WD Control Switch to the desired position.
Shifts between 2WD and 4WD LOCK 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 turn-
ing 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/ 4WD LOCK if the rear wheels are spinning (no
traction). In this situation the selected position indicator
light will flash and the original position indicator lightwill 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.4WD LOCK to 4WD LOW or 4WD LOW to 4WD
LOCK
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 2-3
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 203

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 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 (5) seconds, and retry shift.
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.
204 STARTING AND OPERATING

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 Four-Wheel Drive
(4WD) and indicate the current and desired transfer case
selection (4WD⇔4WD LOCK).
The “SVC 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 theService 4WDlight 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
206 STARTING AND OPERATING

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 thewheels 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 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 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 (5) seconds, and retry the shift.
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.
210 STARTING AND OPERATING

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.
212 STARTING AND OPERATING

WARNING!
•Always 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.
•Be sure the parking brake is fully disengaged
before driving. Failure to do so can lead to brake
failure and an accident.
•Never leave children alone in a vehicle. Leaving
children in a vehicle unattended 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
windows, 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 more than that
required with the power system operating.
If either the front or rear hydraulic system loses 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.
Rear Wheel Anti-Lock Brake System – If
Equipped
This Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically controls the opera-
tion of the rear brakes to prevent rear wheel lockup.
