CAUTION!
Failure to follow the recommended downshifting
speeds may cause the engine to over speed and / or
damage the clutch disc even if the clutch pedal is
depressed.
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 the
desired 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.
STARTING AND OPERATING 233
5

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
(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 the9Shifting Procedure9for your transfer
case, located in this section of the owner's manual.
The ªSVC 4WDº 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 4WD(light is illumi-
nated. Not engaging the parking brake may allow the
vehicle to roll, which may cause personal injury.
234 STARTING AND OPERATING

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
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.
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
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
STARTING AND OPERATING 235

For additional information on the appropriate use of each
transfer case mode position see the information below:
2WD
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.
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.
236 STARTING AND OPERATING

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: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 light
STARTING AND OPERATING 237

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.
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).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.
