The NV233/243 transfer case provides four mode posi-
tions:
•
Two-wheel drive high range (2WD)
•
Four-wheel drive lock range (4WD LOCK)
•
Four-wheel drive low range (4WD LOW)
•
Neutral (N)
The NV233/243 transfer case is designed to be driven in
the two-wheel drive position (2WD) for normal street
and highway conditions on 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 turning the transfer case switch to the
desired position - Refer to “Shifting Procedure” for
further information. The 4WD LOCK and 4WD LOW
positions are designed for loose or slippery road surfaces
only. Driving in the 4WD LOCK and 4WD LOW posi-
tions on dry hard-surfaced roads may cause increased
tire wear and damage to the driveline components.
NOTE: The transfer case NEUTRAL position is selected
by pressing the recessed button located on the lower
left-hand corner of the transfer case switch. The transfer
case NEUTRAL position is to be used for recreational
towing only. Refer to “Recreational Towing” in “Starting
and Operating” for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located on the instrument cluster. If there is
no indicator light on or flashing, the transfer case is in
two-wheel drive (2WD). If the indicator light is on, the
desired position (4WD LOCK and 4WD LOW) has been
obtained.
