Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster. If there is no indicator light on or
flashing, the transfer case position is in two-wheel drive
(2WD). If the indicator light is on, the desired position
(4WD LOCK and 4WD LOW) has been obtained.
If One or More Shift Requirements are not Met:
1. An indicator light will flash.
2. 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
seconds, and retry selection. To find the shift require-
ments, refer to the ЉShifting ProcedureЉ in this section.
The “SVC 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 ؆SVC 4WD؆ light is illumi-
nated. 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 NV233/243 trans-
fer case is not equipped with a synchronizer and there-
fore 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 trans-
fer case.
