Selec-Terrain™ consists of the following posi-
tions:
•Sport – Dry weather, on-road calibration.
Only available in 4WD High range. Perfor-
mance based tuning that provides a rear
wheel drive feel but with improved handling
and acceleration over a two-wheel drive ve-
hicle. The Electronic Stability Control will set
to allow more driver control of vehicle while
maintaining safe handling controls. The ve-
hicle will lower (if equipped with Air Suspen-
sion) to Aero Mode in High Range. 4WD Low
is not available in SPORT mode, if 4WD Low
is selected the Selec-Terrain™ will automati-
cally switch back to AUTO.
• 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 oper-
ating conditions), the transmission may use
second gear (rather than first gear) during
launches, to minimize wheel slippage. If
equipped with air suspension, the level will
change to Normal Ride Height (NRH) if the transfer case is in high range. The level will
change to Off-Road 1 if the transfer case is in
Low range.
• 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 accel-
eration over two-wheel drive vehicles. If
equipped with air suspension, the level will
change to NRH.
• Sand/Mud – Off road calibration for use on
low traction surfaces such as mud, sand, or
wet grass. Driveline is maximized for trac-
tion. Some binding may be felt on less for-
giving surfaces. The electronic brake con-
trols 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.
• 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. If equipped with air
suspension, the vehicle level will change to
Off-Road 2. If the Selec-Terrain™ switch is in
ROCK mode, and the transfer case is
switched from 4WD Low to 4WD High, the
Selec-Terrain™ system will return to AUTO.

QUADRA-LIFT™ — IF EQUIPPED
Description
The Quadra-Lift™ air suspension system pro-
vides full time load leveling capability along
with the benefit of being able to adjust vehicle
height by the push of a button.
214

speed remains between 15 mph (24 km/h)
and 25 mph (40 km/h) for greater than
60 seconds, or the vehicle speed exceeds
25 mph (40 km/h) the Park Mode change will
be cancelled. To exit Park Mode, press the
“Up” button once while in Park Mode or drive
the vehicle over 15 mph (24 km/h).
The Selec-Terrain™ switch will automatically
change the vehicle to the proper height based
on the position of the Selec-Terrain™ switch.
The height can be changed from the default
Selec-Terrain™ setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain™”
in “Starting and Operating” for further informa-
tion.
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. If a door is opened at any time while the
vehicle is lowering the change will not be
completed until the open door(s) is closed.
The Quadra-Lift™ air suspension system uses
a lifting and lowering pattern which keeps the
headlights from incorrectly shining into oncom-
ing 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, it may be noticed
that the air suspension system operates briefly,
this is normal. The system is correcting the
position of the vehicle to ensure a proper
appearance.
To assist with changing a spare tire, the
Quadra-Lift™ air suspension system has a fea-
ture 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. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information. Driving the vehicle over
5 mph (8 km/h) will return the air suspension to
normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for
further information.WARNING!
The air suspension system uses a high pres-
sure volume of air to operate the system. To
avoid personal injury or damage to the sys-
tem, see your authorized dealer for service.

OFF-ROAD DRIVING TIPS
NOTE:
Prior to off-road driving, remove the front air
dam to prevent damage. The front air dam is
attached to the lower front fascia with seven
quarter turn fasteners and can be removed
by hand.
Quadra-Lift™ – If EquippedWhen off-roading, it is recommended that the
lowest useable vehicle height that will clear thecurrent obstacle or terrain be selected. The
vehicle height should then be raised as re-
quired by the changes in terrain.
The Selec-Terrain™ switch will automatically
change the vehicle to the optimized height
based on the Selec-Terrain™ switch position.
The vehicle height can be changed from the
default height for each Selec-Terrain™ mode
by normal use of the air suspension switches.
Refer to “Quadra-Lift™ – If Equipped” in “Start-
ing and Operating” for further information.
When to Use 4WD LOW Range –
If Equipped
When off-road driving, shift to 4WD LOW for
additional traction. This range should be limited
to extreme situations such as deep snow, mud,
or sand where additional low speed pulling
power is needed. Vehicle speeds in excess of
25 mph (40 km/h) should be avoided when in
4WD LOW range.
Driving Through WaterAlthough your vehicle is capable of driving
through water, there are a number of precau-
tions that must be considered before entering
the water.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering, as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
new vehicle limited warranty.
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle. If you must drive through water, try to
determine the depth and the bottom condition
(and location of any obstacles) prior to enter-
ing. Proceed with caution and maintain a
steady controlled speed less than 5 mph
(8 km/h) in deep water to minimize wave ef-
fects.
Flowing Water
If the water is swift flowing and rising (as in
storm run-off), avoid crossing until the water
level recedes and/or the flow rate is reduced. If
you must cross flowing water avoid depths in
excess of 9 in (23 cm). The flowing water can
erode the streambed, causing your vehicle to
