NOTE:
If shift conditions/interlocks are not met a message will
show on the instrument cluster display with instructions
required to complete the shift

4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
the ignition switch in the ON position or the engine run-
ning, shift the transmission into NEUTRAL (N), and push
the 4WD LOW button once on the transfer case switch
until the 4WD LOW indicator light begins to flash in the
instrument cluster. The 4WD LOW light will go out when
the shift is complete.
NOTE:
•
If shift conditions/interlocks are not met a message
will show on the instrument cluster display with
instructions required to complete the shift
page 88.
•
Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being prop-
erly aligned. Several attempts may be required for
clutch teeth alignment and shift completion to
occur. The preferred method is with the vehicle roll-
ing 0 to 3 mph (0 to 5 km/h). If the vehicle is mov-
ing faster than 3 mph (5 km/h), the transfer case
will not allow the shift.
QUADRA-DRIVE II SYSTEM —
IF EQUIPPED
The Quadra-Drive II System features two torque transfer
couplings. The couplings include an Electronic Limited-
Slip Differential (ELSD) rear axle and the Quadra-Trac II
transfer case. The ELSD axle is fully automatic and
requires no driver input to operate. Under normal driv-
ing conditions, the unit functions as a standard axle,
balancing torque evenly between left and right wheels.
With a traction difference between left and right
wheels, the coupling will sense a speed difference. As
one wheel begins to spin faster than the other, torque
will automatically transfer from the wheel that has less
traction, to the wheel that has traction. While the trans-
fer case and axle coupling differ in design, their opera-
tion is similar. Follow the Quadra-Trac II transfer case
shifting information, preceding this section, for shifting
this system.
SELEC-TERRAIN — IF EQUIPPED
SELEC-TERRAIN MODE SELECTION
Selec-Terrain combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains. Tap the toggle up or
down to cycle through the positions.
Selec-Terrain consists of the following positions:
•
ROCK (if equipped) – Off-road calibration is only
available in 4WD LOW. The vehicle is raised
(if equipped with Air Suspension) for improved
ground clearance. Traction-based tuning with
improved steerability for use on high traction off-
road surfaces. Use for low speed obstacles such as
large rocks, deep ruts, etc. If equipped with air sus-
pension, the vehicle level will change to Off-Road 2
