For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2WD
Two-Wheel Drive High Range — This range is for
normal street and highway driving on dry hard
surfaced roads.
4WD HIGH
Four-Wheel Drive High Range — This range
provides torque to the front driveshaft (engages
four-wheel drive) which allows front and rear
wheels to spin at the same speed. This provides
additional traction for loose, slippery road
surfaces only.
4WD LOW
Four-Wheel Drive Low Range — This range
provides low speed four-wheel drive. It
maximizes torque (increased torque over 4WD
HIGH) to the front driveshaft, allowing front and
rear wheels to rotate at the same speed. This
range provides additional traction and
maximum pulling power for loose, slippery road
surfaces only. Do not exceed 25 mph (40 km/h)
in this range.
N (Neutral)
N (Neutral) — This range disengages both the
front and rear driveshafts from the powertrain.
To be used for flat towing behind another
vehicle. Refer to "Recreational Towing" in this
section for further information.
WARNING!
You or others could be injured or killed if you

leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking brake.
The transfer case NEUTRAL (N) position
disengages both the front and rear drive
shaft 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.
The transmission may not engage PARK if the

vehicle is moving. Always bring the vehicle to
a complete stop before shifting to PARK, and
verify that the transmission gear position indi-
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
STARTING AND OPERATING
This electronically shifted transfer case is
designed to be driven in the two–wheel drive
position (2WD) for normal street and highway
conditions on dry hard surfaced roads. Driving
the vehicle in 2WD will have greater fuel
economy benefits as the front axle is not
engaged in 2WD.
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 pushing the desired position
on the 4WD control switch.
Refer to "Shifting Procedure" in this section for
specific shifting instructions.
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 surfaced roads may cause
increased tire wear and damage to the driveline
components.
