STARTING AND OPERATING
3. If the transfer case will not shift, a message
will appear on the cluster 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.
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 2WD 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
If any of the requirements to select a new
transfer case position have not been met, then
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, then the current
position indicator light will turn off and 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.
