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 transfer case switch back to the original
position, make certain all shift requirements have been
met, wait five seconds, and try the shift again.
2WD-to-4WD LOCK or 4WD LOCK-to-2WD
Turn the transfer case 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 transfer case 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 ACC position.
NOTE: On vehicles equipped with Anti-Lock Brake
Systems, the four-wheel drive 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 posi-
tion indicator light 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.
