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/RUN position or the
engine running, shift the transmission
into NEUTRAL, and press the “4WD
LOW” button once on the transfer
case switch. The “4WD LOW”
indicator light in the instrument cluster
will flash and turn off when the shift is
complete.
NOTE:
• If the shift conditions/interlocks are not met, or a transfer case motor
temperature protection exists, a “For 4x4
Low Slow Below 5 MPH or 8 KPH Put
Trans in N Press 4 Low” message will
flash on the Electronic Vehicle
Information Center (EVIC).
• 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.
NEUTRAL Shift Procedure
• Turn the ignition switch to theON/RUN position, engine off.
• Vehicle stopped, with foot on brake.
• Place the transmission into NEUTRAL. • Press and hold the NEUTRAL button
located near the 4WD mode control
knob with a pen or similar object for
four seconds. The indicator light will
begin to flash indicating the shift is in
progress. The light will stop blinking
(stay on solid) when the NEUTRAL shift
is complete. A “4WD SYSTEM IN
NEUTRAL” message will display on
the Electronic Vehicle Information
Center (EVIC).
• Repeat these Steps to shift out of NEUTRAL.
SELEC-TERRAIN™
• Selec-Terrain™ combines thecapabilities of the vehicle control
systems, along with driver input, to
provide the best performance for all
terrains.
Rotate the mode control knob to select the
following Selec-Terrain™ positions: • Sport – Dry weather, on-road
calibration. Only available in 4WD
High range. Performance-based
tuning that provides a rear wheel
drive feel but with improved handling
and acceleration over a two-wheel
drive vehicle. The Electronic Stability
Control will set to allow more driver
control of the vehicle while
maintaining safe handling controls.
The vehicle will lower (if equipped
with Air Suspension) by 0.59 inches
(15 mm) in the SPORT mode.
• Snow – The Electronic Stability
Control is set for additional stability in
inclement weather. Use on and off
road on loose traction surfaces such
as snow.
• Auto – Fully automatic full-time
four-wheel drive operation can be
used on and off road. Balances
traction with steering feel to provide
improved handling and acceleration
over two-wheel drive vehicles.
OFF-ROAD CAPABILITIES
57

•Sand/Mud – Off-road calibration
for use on low traction surfaces such
as mud, sand, or wet grass. 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.
• Rock – Off-road calibration only
available in 4WD Low range. The
vehicle is raised (if equipped with Air
Suspension) for improved ground
clearance. Traction based tuning with
improved steer-ability for use on high
traction off-road surfaces. Activates
the Hill Descent Control for steep
downhill control. Use for low speed
obstacles such as large rocks, deep
ruts, etc.
Quadra-Lift™
• The Quadra-Lift™ air suspension system provides full time load leveling
capability along with the benefit of
being able to adjust vehicle height by
the push of a button. Quadra-Lift™ is
available with both Quadra-Trac II
®
and Quadra-Drive II™.
• The system requires that the engine be running for all changes. When
lowering the vehicle all of the doors,
including the liftgate, must be closed. • The Quadra-Lift™ air suspension
system uses a lifting and lowering
pattern which keeps the headlights
from shining into oncoming traffic.
When raising the vehicle, the rear of
the vehicle will move up first and then
the front. When lowering the vehicle,
the front will move down first and then
the rear.
• After the engine is turned off, you may notice that the air suspension system
operates briefly. This is normal. The
system is correcting the position of the
vehicle.
• To assist with changing a spare tire, the Quadra-Lift™ air suspension
system has a feature which allows the
automatic leveling to be disabled.
Press and hold both the “Up” and
“Down” buttons simultaneously
between 5 and 10 seconds; a
message will appear in the EVIC
stating leveling has been disabled
immediately after both buttons have
been released. Driving the vehicle
over 5 mph (8 km/h) will return the
air suspension to normal operation.
• An audible chime will be heard whenever a system error has been
detected.
Operation • Pressing the “Up” or “Down” button once will move the suspension one
position higher or lower from the
current position, assuming all
conditions are met (i.e., engine
running and all doors and liftgate
closed).
• The 4 indicator lamps will illuminate to show the current position of the
vehicle. Flashing indicator lamps will
show a position which the system is
working to achieve. If multiple
indicator lamps are flashing on the
“Up” button, the highest flashing
indicator lamp is the position the
system is working to achieve.
OFF-ROAD CAPABILITIES
58

• Normal Ride Height(NRH) – This is the
standard position of the
suspension and is meant
for normal driving. Only
the bottom Indicator lamp
on the “Up” button will be illuminated
when the vehicle is in this position.
• Off-Road 1 (OR1) (Raisesthe vehicle approximately
1.3 in (33 mm) – This
position is intended for
off-road driving only
where vehicle speeds may
go above 25 mph (40 km/h). Press
the “Up” button once from NRH while
vehicle speed is below 48 mph
(77 km/h). The bottom two Indicator
lamps on the “Up” button will be
illuminated when the vehicle is in
OR1.
• Off-Road 2 (OR2) (Raisesthe vehicle approximately
2.6 in (65 mm) – This
position is intended for
off-road driving where
maximum ground
clearance is required. Press the “Up”
button twice from NRH, or once from
OR1 position while vehicle speed is
below 20 mph (32 km/h). All three
Indicator lamps on the “Up” button
will be illuminated when the vehicle is
in OR2.
• Park Mode (Lowers thevehicle approximately
1.5 in (38 mm) – This
position lowers the vehicle
for easier passenger entry
and exit. Press the
“Down” button once from NRH while
the vehicle speed is below 25 mph
(40 km/h). Once the vehicle speed
goes below 15 mph (24 km/h) the
vehicle height will begin to lower. The
Indicator lamp on the “Down” button
will be illuminated when the vehicle is
in Park Mode.WARNING!
• You or others could be injured 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
driveshafts from the powertrain and
will allow the vehicle to move
regardless of the transmission
position. The parking brake should
always be applied when the driver
is not in the vehicle.
• The air suspension system uses a high pressure volume of air to
operate the system. To avoid
personal injury or damage to the
system, see your authorized dealer
for service.
Hill Start Assist/Hill
Descent Control
• The Hill Start Assist system assists the
driver when starting a vehicle from a
stop on a hill.
• The Hill Descent Control system maintains vehicle speed while
descending hills during off-road
driving situations and is available in
4WD HIGH range and 4WD LOW
range.
• Refer to your Owner's Manual on the DVD for further details.

CAUTION!
• When installing the integrated power module cover, it is important to ensure the cover is properly positioned and fully latched. Failure to do so may allow water
to get into the integrated power module and possibly result in a electrical system
failure.
• When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated
may result in a dangerous electrical system overload. If a properly rated fuse
continues to blow, it indicates a problem in the circuit that must be corrected.
