FOUR-WHEEL DRIVE OPERATION
• This is an electric-shift transfer caseand is operated by the 4WD Control
Switch (Transfer Case Switch), which
is located on the instrument panel.
• The transfer case provides four mode positions:
• Two-wheel drive high range (2WD)
• Four-wheel drive lock range (4WD
LOCK)
• Four-wheel drive low range (4WD LOW)
• NEUTRAL (N)
• This 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 rotating the 4WD Control Switch to the desired position. 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 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 4WD Control Switch. The
transfer case NEUTRAL position is to be used for recreational towing only.
NOTE: Do not attempt to make a shift while only the front or rear wheels are
spinning. The NV233/243 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.
WARNING!
You or others could be injured if you leave the vehicle unattended with the
transfer case in the NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL 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.
