STARTING AND OPERATING
25
If the transfer case does not shift into the desired
position, one or more of the following events may
occur:
1. The indicator light for the current position will
remain on.
2. The newly selected position indicator light will
continue to flash.
3. If the transfer case will not shift, there will be a
cluster message stating the 4WD shift has
canceled.
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, push the current position, wait five
seconds, and retry selection. To find the shift
The SERV 4WD Warning Light monitors the
electronic 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. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 4WD AUTO or 4WD HIGH positions at a given
road speed. Take care not to overspeed the engine
and do not exceed 55 mph (88 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 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.
If all the requirements to select a new transfer
case position have been met, the current position
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 posi
-
tion will stop flashing and remain on.
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 or death.
