When additional traction is required, the transfer case
4WD HIGH and 4WD LOW positions can be used to
maximize torque to the front driveshaft, forcing the
front and rear wheels to rotate at the same speed. This
is accomplished by rotating the four-wheel drive Control
Switch to the desired position.
For specific shifting instructions page 121.
The 4WD HIGH and 4WD LOW positions are designed
for loose, slippery road surfaces only. Driving in the
4WD HIGH and 4WD LOW positions on dry hard sur-
faced roads may cause increased tire wear and dam-
age to the driveline components.
NOTE:
The transfer case N (Neutral) button is located on the
lower left hand corner of the four-wheel drive Control
Switch. The transfer case N (Neutral) position is to be
used for recreational towing only
page 161.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4WD LOW) are located in the instrument cluster and
indicate the current and desired transfer case selec-
tion. 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 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 Of The Following 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 switch back to the current position, wait
five seconds, and retry selection
page 121.
The SERV 4WD Warning Light monitors the electroni-
cally shifted 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.
WARNING!
Always engage the parking brake when powering
down the vehicle if the SERV 4WD Warning 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.
When operating your vehicle in 4WD LOW, the engine
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 depends
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 indicator light for the previous posi-
tion 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 position indica-
tor 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 indi-
cator light for the selected position will stop flashing
and remain ON.
