122 STARTING AND OPERATING
If shift conditions are not met, 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. 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 Ú page 123.
The "SERV AWD" Warning Light monitors the
electronic shift all-wheel drive system. If this
light remains on after engine start up or
illuminates during driving, it means that the
all-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 AWD
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. This could
cause damage to driveline components.
When operating your vehicle in AWD LOW, the
engine speed is approximately three times that
of the AWD AUTO position at a given road speed.
Take care not to overspeed the engine and do
not exceed 25 mph (40 km/h).
Proper operation of all-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 transfer case.
Because all-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.
For additional information on the appropriate
use of each transfer case mode position, see
the information below:
AWD LOW
All-Wheel Drive Low Range – This range
provides low speed all-wheel drive. Locks the
front and rear driveshafts together forcing the
front and rear wheels to rotate at the same
speed. Additional traction and maximum pulling
power for loose, slippery road surfaces only.
Do not exceed 25 mph (40 km/h).
NEUTRAL (N)
This range disengages both the front and rear
driveshafts from the powertrain. To be used for
flat towing behind another vehicle Ú page 166.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL position without first fully
engaging the parking brake. The transfer case
NEUTRAL position disengages both the front
and rear drive shafts from the powertrain and
will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake
should always be applied when the driver is not
in the vehicle.
