Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:This mode is intended to be enabled with engine
running.
Transport Mode
To assist with flat bed towing, the air suspension system
has a feature which will put the vehicle into Entry/Exit
height and disable the automatic load leveling system.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information.
NOTE: This mode is intended to be enabled with engine
running. Wheel Alignment Mode
Before performing a wheel alignment this mode must be
enabled. Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information.
NOTE:
This mode is intended to be enabled with engine
running.
Protection Mode
In order to “protect” the air suspension system, the
vehicle will enter Protection Mode when load leveling
cannot be achieved. Some driving may be required to
clear the protection mode telltale in the EVIC. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.

by one position down to a minimum of Entry/Exit Mode
or the lowest position allowed based on current condi-
tions (i.e. vehicle speed, etc.)
Automatic height changes will occur based on vehicle
speed and the current vehicle height. The indicator lamps
and EVIC messages will operate the same for automatic
changes and user requested changes.
•Off-Road 2 (OR2) – Indicator lamps 3, 4, 5, and 6 will
be illuminated when the vehicle is in OR2.
• Off-Road 1 (OR1) – Indicator lamps 3,4 and 5 will be
illuminated when the vehicle is in OR1.
• Normal Ride Height (NRH)/Aero Mode – Indicator
lamps 3 and 4 will be illuminated when the vehicle is
in this position.
• Entry/Exit Mode – Indicator lamp 3 will be illumi-
nated when the vehicle is in Entry Exit Mode. Entry/
Exit mode can be requested up to 33 mph (53 km/h). If vehicle speed is reduced to, and kept below, 15 mph
(24 km/h) indicator lamp 4 will flash and indicator
lamp 3 will remain solid until Entry/Exit Mode is
achieved at which point indicator lamp 4 will turn off.
• Transport Mode – No indicator lamps will be illumi-
nated. Transport Mode is disabled by driving the
vehicle.
• Tire/Jack Mode – indicator lamps 3 and 6 will be
illuminated. Tire/Jack Mode is disabled by driving the
vehicle.
• Wheel Alignment Mode – indicator lamps 3 and 4 will
be illuminated. Wheel Alignment Mode is disabled by
driving the vehicle.

NOTE:The rear axle must be locked before the front axle
will lock.
To unlock the front axle; move the axle locker switch to
REAR LOCK. The FRONT/REAR LOCK indicator light
will go out when the axle is unlocked.
NOTE: The axle lockers could be torque locked due to
side to side loads on the axle. Driving slowly while
turning the steering wheel from a left hand turn to a right
hand turn or driving in REVERSE for a short distance
may be required to release the torque lock and unlock the
axles.
To unlock the rear axle; move the axle locker switch to
AXLE UNLOCK. The REAR LOCK indicator light will go
out when the rear axle is unlocked.STABILIZER/SWAY BAR SYSTEM — POWER
WAGON ONLY
Your vehicle is equipped with an electronic disconnecting
stabilizer/sway bar. This system allows greater front
suspension travel in off-road situations.
Due to the use of taller springs, this vehicle has an
increased ride height of approximately 1.9 in (48.3 mm)
in the front and 1.5 in (38.1 mm) in the rear. A major
advantage to increasing ride height is the positive effect
it has on approach/departure and break over angles.
This system is controlled by the electronic control sway
bar switch located on the instrument panel.
420 STARTING AND OPERATING

To disconnect the stabilizer/sway bar, shift to either 4HI
or 4LO as shown in “Four Wheel Drive Operation” and
press the right hand Off Road stabilizer/sway bar button
to obtain the Off-Road position. The amber indicator
light will flash until the stabilizer/sway bar has been
fully disconnected.
NOTE:The stabilizer/sway bar may be torque locked
due to left and right suspension height differences. This
condition is due to driving surface differences or vehicle
loading. In order for the stabilizer/sway bar to
disconnect/reconnect, the right and left halves of the bar
must be aligned. This alignment may require that the
vehicle be driven onto level ground or rocked from side
to side.
To return to the On-Road mode; press the left hand On
Road stabilizer/sway bar button.WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is greatly reduced. Do not
attempt to drive the vehicle over 18 mph (29 km/h).
Driving faster than 18 mph (29 km/h) may cause loss
of control of the vehicle, which could result in
serious injury or death. Contact your local service
center for assistance.

Off-Road Driving Tips And Vehicle Characteristics
Your vehicle has excellent on and off-road capabilities.
These off-road capabilities will allow you to explore
those wilderness trails where few travel, providing a

CAUTION!
The door sill height is 25 inches. Water may intrude
into the interior of the vehicle at greater depths.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simultane-
ous use of the brake and throttle (two footed driving).
When climbing rocks, logs, or other stepped objects,
using light brake pressure with light throttle will keep the
vehicle from jerking or lurching. This technique is also
used when you need to stop and restart a vehicle on a
steep incline.
The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-
road. You should be familiar with the terrain and area
before proceeding. There are many types of surface
conditions: hard packed dirt, gravel, rocks, grass, sand,mud, snow and ice. Every surface has a different effect on
your vehicle’s steering, handling and traction. Control-
ling your vehicle is one of the keys to successful off-road
driving, so always keep a firm grip on the steering wheel
and maintain a good driving posture. Avoid sudden
accelerations, turns or braking. In most cases there are no
road signs, posted speed limits or signal lights. Therefore
you will need to use your own good judgment on what is
safe and what isn’t. When on a trail you should always be
looking ahead for surface obstacles and changes in
terrain. The key is to plan your future driving route while
remembering what you are currently driving over.
CAUTION!
Never park your vehicle over dry grass or other
combustible materials. The heat from your vehicle
exhaust system could cause a fire.

compact spare tires have the letter “T” or “S” molded
into the sidewall preceding the size designation. Ex-
ample: T145/80D18 103M.•
High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

EXAMPLE:
Size Designation: P= Passenger car tire size based on U.S. design standards
....blank.... = Passenger car tire based on European design standards
LT = Light truck tire based on U.S. design standards
TorS= Temporary spare tire
31 = Overall diameter in inches (in)
215 = Section width in millimeters (mm)
65 = Aspect ratio in percent (%)
— Ratio of section height to section width of tire
10.5 = Section width in inches (in)

measure GTW is to put your fully loaded trailer on a
vehicle scale. The entire weight of the trailer must be
supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
NOTE:The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting and Operating” for further
information.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. In most cases it should not be
more than 10% of the trailer load. You must consider this
as part of the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
