Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD
a
n
d 4LOW) are located in the instrument cluster
and indicate the current and desired transfer case
selection. When you select a different transfer
case position, the indicator lights will do the
following:
If All Of The Following Shift Conditions Are Met:
1. The current position indicator light will turn
O
FF.
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 Of The Following Shift Conditions
Ar
e Not Met:
1. The indicator light for the current position will
remain ON.
2. The newly selected position indicator light will
continue to flash.
3. The transfer case will not shift.
NOTE:
Before retrying a selection, make certain that all the
ne
cessary requirements for selecting a new transfer
case position have been met. To retry the selection,
turn the control switch back to the current position,

The “SVC 4WD Warning Light” monitors the
e
lectronic shift four-wheel drive system. If this light
remains on after engine start up or illuminates
during driving, it means that the four-wheel drive
system is not functioning properly and that service
is required.
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.
When operating your vehicle in 4WD Low, the
en
gine speed is approximately three times that of
the two-wheel drive or 4WD High positions at a
given road speed. Take care not to overspeed the
engine and do not exceed 25
mph (40 km/h).
Proper operation of four-wheel drive vehicles
de
pends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the drivetrain.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
Shifting Procedure
NOTE:
If any of the requirements to select a new
transfer case position have not been met, the
transfer case will not shift. The position indi
-
cator light for the previous position will remain
ON
and the newly selected position indicator
light will continue to flash until all the require
-
ments for the selected position have been met.
To
retry a shift: return the control switch back to
the original position, make certain all shift
requirements have been met, wait five seconds
and try the shift again.
If all the requirements to select a new transfer
case position have been met, the current posi
-
tion indicator light will turn OFF, the selected
position indicator light will flash until the
transfer case completes the shift. When the
shift is complete, the position indicator light for
the selected position will stop flashing and
remain ON.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light”
is illuminated. Not engaging the parking brake
may allow the vehicle to roll, which may cause
personal injury.
