274 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.
NOTE:
The transfer case NEUTRAL button is located in the center of
the 4WD Control Switch and is pushed by using a ballpoint
pen or similar object. The transfer case NEUTRAL position is
to be used for recreational towing only. Refer to “Recre-
ational Towing” in “Starting And Operating” for further
information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located in the instrument cluster and indicate the
current and desired transfer case selection. 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.
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 transmis-
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.
