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

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: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

Recreational Towing 4WD Models
CAUTION!
Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
NOTE:Both the NV233 and NV244 HD transfer cases
must be shifted into Neutral (N) for recreational towing.
The Neutral (N) selection button is located on the lower
left hand corner of the 4WD Control Switch. Shifts into
and out of transfer case Neutral (N) can take place with
the selector switch in any mode position. Automatic
Transmissions must be placed in P (Park) position for
recreational towing. Manual Transmissions must be
placed in gear (for example, 4th gear) for recreational
towing.
Recreational Towing Procedure
Use the following procedure to prepare your vehicle for
recreational towing.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in Neutral (N) before
recreational towing to prevent damage to internal
parts.
1. Bring vehicle to a complete stop.
2. Shut engine OFF.
3. Place ignition key in the ON position.
4. Depress brake pedal.
5. Shift automatic transmission to Neutral (N) or depress
clutch on manual transmission.
