•
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situ-
ations (i.e., in highway construction zones).
•When entering a turn lane or highway off
ramp; when driving on roads that are wind-
ing, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
Failure to follow these warnings can result in
a collision and death or serious personal
injury. The Cruise Control system has two control
modes:
•
Adaptive Cruise Control mode for maintaining
an appropriate distance between vehicles.
•Normal (fixed speed) cruise control mode for
cruising at a constant preset speed. For addi-
tional information, refer to “Normal (Fixed

TEM OVER TEMP” message and
a icon are displayed on the EVIC
screen, it indicates that extreme
steering maneuvers may have oc-
curred, which caused an over tem-
perature condition in the power steering sys-
tem. You will lose power steering assistance
momentarily until the over temperature condi-
tion no longer exists. Once driving conditions
are safe, then pull over and let vehicle idle. After
five minutes, the system will cool and return to
normal operation. Refer to “Power Steering” in
“Starting and Operating” for further information.
NOTE:
•
Even if power steering assistance is no
longer operational, it is still possible to
steer the vehicle. Under these conditions
there will be a substantial increase in steer-
ing effort, especially at very low vehicle
speeds and during parking maneuvers.
• If the condition persists, see your autho-
rized dealer for service.

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®
transfer case. The optional ELSD axle is fully
automatic and requires no driver input to oper-
ate. 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 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 sec-
tion, for shifting this system.
SELEC-TERRAIN™ — IF
EQUIPPED
DescriptionSelec-Terrain™ combines the capabilities of the
vehicle control systems, along with driver input,
to provide the best performance for all terrains.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 operat-
ing 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.
Selec-Terrain™ Switch

•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 accelera-
tion 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 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 suspen-
sion, 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. Activate 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™ sys-
tem will return to AUTO.

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 ap-
pearance.
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 immediatelyafter 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.

in “Understanding Your Instrument Panel” for
further information.
An audible chime will be heard whenever a
system error has been detected.
OperationThe indicator lamps 3 through 6 will illuminate to
show the current position of the vehicle. Flash-
ing indicator lamps will show a position which
the system is working to achieve. When raising,
if multiple indicator lamps are flashing on the
“Up” button, the highest flashing indicator lamp
is the position the system is working to achieve.
When lowering, if multiple indicators are flash-
ing on the
"Up"button the lowest solid indicator
lamp is the position the system is working to
achieve.
Pressing the “UP” button once will move the
suspension one position higher from the current
position, assuming all conditions are met (i.e.
engine running, speed below threshold, etc).
The “UP” button can be pressed multiple times,
each press will raise the requested level by one
position up to a maximum position of OR2 or the
highest position allowed based on current con-
ditions (i.e. vehicle speed, etc).
