130STARTING AND OPERATING
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
AutoStick — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
AutoStick Paddle Shifters
Operation
To activate AutoStick mode, tap one of the paddle
shifters on the steering wheel. Tapping the (-)
paddle shifters to enter AutoStick mode will
downshift the transmission to the next lower gear,
while tapping (+) to enter AutoStick mode will
retain the current gear. The current transmission
gear will be displayed in the instrument cluster. In
AutoStick mode, you can use the paddle shifters,
to manually shift the transmission. Tapping the (-)
paddle shifters, will downshift the transmission to
the next lower gear. Tapping the (+) paddle
shifters, will upshift the transmission to the next
highest gear.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition
would result. It will remain in the selected gear
until another upshift or downshift is chosen, except
as follows.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans
-
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) at a stop will allow
starting in SECOND gear. Starting out in SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Holding the (-) paddle pressed, will downshift
the transmission to the lowest gear possible at
the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected. The
vehicle will force an upshift, but it will stay in
AutoStick mode.
To disengage AutoStick mode, push and hold the
(+) paddle shifters until "D" is once again indicated
in the instrument cluster. You can shift in or out of
AutoStick mode at any time without taking your
foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

132STARTING AND OPERATING
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference will
adversely affect performance and function of the
transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
SHIFT POSITIONS
For additional information on the appropriate use
of each four-wheel drive system mode position,
see the following:
4WD HI
This is the default operating range 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 195.
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/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 a “To Complete 4WD Shift Speed Must Be Below
3 MPH” or a “To Complete 4WD Shift Allow Engine
To Return To Idle” message will flash from the
instrument cluster display Ú page 98.
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.

STARTING AND OPERATING133
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 Cancelled” or “4WD Shift Aborted/
Retry Shift” message will be displayed on the
instrument cluster. To reattempt 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 a “To Complete 4WD Shift Speed
Must Be Below 3 MPH” or a “To Complete 4WD
Shift Allow Engine To Return To Idle” message
will flash from the instrument cluster display
Úpage 98.
Shifting into or out of 4WD LOW is possible with
the vehicle completely stopped; however, diffi -
culty 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-TRAC II SYSTEM —
I
F EQUIPPED
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. Follow the Quadra-Trac II
transfer case shifting information, preceding this
section, for shifting this system.
ELECTRONIC SWAY BAR DISCONNECT —
I
F EQUIPPED
Your vehicle may be equipped with an electronic
disconnecting stabilizer/sway bar. This system
allows greater front suspension travel in off-road
situations.
This system is controlled by the SWAY BAR switch
located on the instrument panel (to the right of the
gear selector).

Selec-Terrain
Selec-Terrain consists of the following positions:
ROCK – Off-road calibration is only available in
4WD LOW. The vehicle is raised (if equipped
with air suspension) for improved ground clear -
ance. 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
suspension, the vehicle level will change to
Off-Road 2 (OR2). If the Selec-Terrain switch is
in ROCK mode, and the transfer case is
switched from 4WD LOW to 4WD HI, the
Selec-Terrain system will return to AUTO.
SAND/MUD – Off-road calibration for use on low
traction surfaces such as mud or sand. Driveline
is maximized for traction. Some binding may be
felt on less forgiving surfaces. The electronic
brake controls are set to limit traction control
management of throttle and wheel spin. If
equipped with air suspension, the level will
change to Off-Road 1 (OR1).
SNOW – Tuning set for additional stability in
inclement weather. Use on and off-road on
loose traction surfaces such as snow. When in
SNOW mode (depending on certain operating
conditions), the transmission may use SECOND
gear (rather than FIRST gear) during launches,
to minimize wheel slippage. If equipped with air
suspension, the default ride height for SNOW is
Normal Ride Height (NRH).
AUTO – Fully automatic full-time four-wheel
drive operation can be used on and off-road.
Balances traction with seamless steering feel to
provide improved handling and acceleration
over two-wheel drive vehicles. If the suspension
is already in OR1 or OR2, the vehicle will not
lower to NRH with Auto selection as to maintain
capability.
NOTE:If equipped with air suspension, the level will only
raise to Normal Ride Height (NRH) in the AUTO
mode. If the vehicle is in OR1 or OR2 the height will
not lower automatically until defined speed
thresholds are exceeded.
SPORT – This mode is only available in 4WD HI.
When activated, the engine and transmission,
steering and suspension (if equipped with air
suspension) are all set to their SPORT settings.
SPORT mode will provide improved throttle
response and modified transmission shift
points as well as firmer suspension and
steering, the vehicle will also be dropped to Aero
Height for an enhanced driving experience.
When SPORT mode has been activated, an indi -
cator light will illuminate in the instrument
cluster.
