case selection. When you select a different transfer case
position, the indicator lights will do the following:
If All Shift Requirements are Met
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until the
transfer case completes the shift.
3. When the shift is complete, the indicator light for the
selected position will stop flashing and remain ON.
If One or More Shift Requirements are not Met
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will flash.
3. The transfer case will not shift.
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 the ЉShifting ProcedureЉ for your transfer
case, located in this section of the owner’s manual.
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 the ؆Service 4WD؆ light is
illuminated. 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 the
