126 STARTING AND OPERATING
SHIFT POSITIONS
For additional information on the appropriate use of each
four-wheel drive system mode position, see the following
information:
4WD HI
This range is the default operating mode for daily use.
N (NEUTRAL)
This range disengages the driveline from the powertrain. It
is used for towing your vehicle behind another vehicle
Ú page 181.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slippery
road surfaces. Do not exceed 25 mph (40 km/h).
SHIFTING PROCEDURES
4WD HI To 4WD LOW
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 running,
shift the transmission into NEUTRAL (N), and push and
hold 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 remain on
solid when the shift is complete.
4WD LOW Button
NOTE:
If shift conditions/interlocks are not met a message will
show on the instrument cluster display with instructions
required to complete the shift
Ú page 96.
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 running,
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 instruc-
tions required to complete the shift
Ú page 96.
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 properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The
preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph
(5 km/h), the transfer case will not allow the shift.
QUADRA-DRIVE II SYSTEM —
I
F 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 driving 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 transfer case and axle coupling differ in
design, their operation is similar. Follow the Quadra-Trac II
transfer case shifting information, preceding this section,
for shifting this system.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (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.
