HIFTING ROCEDURES
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/RUN position and the engine
running, shift the transmission into NEUTRAL (N), push
and hold the 4WD LOW button until the 4WD LOW
Indicator Light begins to flash in the instrument cluster.
When the shift is complete, the 4WD LOW Indicator Light
will remain on solid.
4WD LOW Button
NOTE:
If shift conditions/interlocks are not met, a "To Complete
4WD Shift Put Transmission In Neutral" or "To Complete
4WD Shift Speed Must Be Below 3 MPH" or "To Complete
4WD Shift Allow Engine To Return To Idle" will flash from
the instrument cluster display page 84.
Ú
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), push and hold
the 4WD LOW button until the 4WD LOW Indicator Light
begins to flash in the instrument cluster. When the shift is
complete, the 4WD LOW Indicator Light will remain off.
NOTE:
 If shift conditions/interlocks are not met, "4WD Shift
Canceled" or "4WD Shift Aborted/ Retry Shift" will
display on the instrument cluster. To re-attempt shift,
put the transmission in NEUTRAL (N) and push and
hold the 4WD LOW button.
 If shift conditions/interlocks are not met, a
"To Complete 4WD Shift Put Transmission In Neutral"
or "To Complete 4WD Shift Speed Must Be
Below 3 MPH" or "To Complete 4WD Shift Allow
Engine To Return To Idle" will flash from the instrument
cluster display page 84.
Ú
STARTING AND OPERATING
 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.

The Quadra-Trac 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.
