114 STARTING AND OPERATING
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 only. 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 “N”, and push the “4WD
LOW” button once on the transfer case switch.
The “4WD LOW” indicator light in the instrument
cluster will begin to flash and remain on solid
when the shift is complete.
Transfer Case Switch
NOTE:
If shift conditions/interlocks are not met, or a
transfer case motor temperature protection
condition exists, a “For 4x4 Low Slow Below
3 mph (5 km/h) Put Trans in “N” Press 4 Low”
message will flash from the instrument cluster
display Ú page 81.
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, and push the “4WD
LOW” button once on the transfer case switch.
The “4WD LOW” indicator light in the instrument
cluster will flash and go out when the shift is
complete.
NOTE:
If shift conditions/interlocks are not met, or a
transfer case motor temperature protection
condition exists, a “For 4x4 High Slow Below
3 mph (5 km/h) Put Trans in NEUTRAL push
4 Low” message will flash from the instru-
ment cluster display Ú page 81.
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 — IF
E
QUIPPED
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.
