If One or More Shift Conditions are not Met
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will con-
tinue to 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, as this can cause
damage to driveline components.
