• Shifting into or out of 4WD LOW is pos-
sible with the vehicle completely stopped;
however, difficulty may occur due to the
mating clutch teeth not being properly
aligned. Several attempts may be re-
quired 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.
NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position,
engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL "pin" switch (with
a pen, etc.) for four seconds until the LED light
by the switch starts to blink indicating shift in
progress. The light will stop blinking (stay on
210
solid) when the NEUTRAL shift is complete. A
"To Tow Vehicle Safely, Read Neutral Shift Pro-
cedure in Owners Manual" message will dis-
play on the Electronic Vehicle Information Cen-
ter (EVIC). Refer to "Electronic Vehicle
Information Center (EVIC)" in "Understanding
Your Instrument Panel" for further information.
Neutral Switch
5. Repeat Steps 1 to 4 to shift out of NEUTRAL.
NOTE:
If shift conditions/interlocks are not met, a
"To Tow Vehicle Safely, Read Neutral Shift
Procedure in Owners Manual" message will
flash from the Electronic Vehicle Informa-
tion Center (EVIC). Refer to "Electronic Ve-
hicle Information Center (EVIC)" in "Under-
standing Your Instrument Panel" for further
information.
Quadra-Drive II System –
If Equipped
The optional 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 trans-
fer case. The optional ELSD axle is fully auto-
matic and requires no driver input to operate.
Under normal driving conditions, the unit func-
tions 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 differ-
ence. 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.
