HOW TO USE THIS MANUAL
Essential Information
Each time direction instructions (left/right or
forwards/backwards) about the vehicle are
given, these must be intended as regarding
an occupant in the driver's seat. Special
cases not complying with this rule will be
properly specified in the text.
The figures in this User Guide are provided by
way of example only: this might imply that
some details of the image do not correspond
to the actual arrangement of your vehicle.
In addition, the User Guide has been con-
ceived considering vehicles with the steering
wheel on the left side; it is therefore possible
that in vehicles with the steering wheel on the
right side, the position or construction of
some controls is not exactly mirror-like with
respect to the figure.
To identify the chapter with the information
needed you can consult the index at the end
of this User Guide.Chapters can be rapidly identified with dedi-
cated graphic tabs, at the side of each odd
page. A few pages further there is a key for
getting to know the chapter order and the
relevant symbols in the tabs. There is always
a textual indication of the current chapter at
the side of each even page.
Symbols
Some vehicle components have colored la-
bels whose symbols indicate precautions to
be observed when using this component.
Refer to “Warning Lights and Messages” in
“Getting To Know Your Instrument Panel” for
further information on the symbols used in
your vehicle.
ROLLOVER WARNING
Utility vehicles have a significantly higher
rollover rate than other types of vehicles. This
vehicle has a higher ground clearance and a
higher center of gravity than many passenger
vehicles. It is capable of performing better in
a wide variety of off-road applications. Driven
in an unsafe manner, all vehicles can go outof control. Because of the higher center of
gravity, if this vehicle is out of control it may
roll over when some other vehicles may not.
Do not attempt sharp turns, abrupt maneu-
vers, or other unsafe driving actions that can
cause loss of vehicle control. Failure to oper-
ate this vehicle safely may result in a colli-
sion, rollover of the vehicle, and severe or
fatal injury. Drive carefully.
Failure to use the driver and passenger seat
belts provided is a major cause of severe or
fatal injury. In a rollover crash, an unbelted
person is significantly more likely to die than
a person wearing a seat belt. Always buckle
up.

•Off-Road 1 (OR1) (Raises the vehicle approxi-
mately 1.1 inches (28 mm))– This is the
primary position for all off-road driving until
OR2 is needed. A smoother and more com-
fortable ride will result. Push the “UP”
button once from the NRH position while
the vehicle speed is below 38 mph
(61 km/h). When in the OR1 position, if the
vehicle speed remains between 40 mph
(64 km/h) and 50 mph (80 km/h) for
greater than 20 seconds or if the vehicle
speed exceeds 50 mph (80 km/h), the
vehicle will be automatically lowered to
NRH.
•Off-Road 2 (OR2) (Raises the vehicle approxi-
mately 2.2 inches (55 mm))– This position is
intended for off-roading use only where
maximum ground clearance is required. To
enter OR2, push the “UP” button twice
from the NRH position or once from the
OR1 position while vehicle speed is below
20 mph (32 km/h). While in OR2, if the
vehicle speed exceeds 25 mph (40 km/h)
the vehicle height will be automatically
lowered to OR1.•Aero Mode (Lowers the vehicle approximately
0.6 inches (15 mm))– This position provides
improved aerodynamics by lowering the ve-
hicle. The vehicle will automatically enter
Aero Mode when the vehicle speed remains
between 52 mph (83 km/h) and 56 mph
(90 km/h) for greater than 20 seconds or if
the vehicle speed exceeds 56 mph
(90 km/h). The vehicle will return to NRH
from Aero Mode if the vehicle speed re-
mains between 20 mph (32 km/h) and
25 mph (40 km/h) for greater than 20 sec-
onds or if the vehicle speed falls below
20 mph (32 km/h). The vehicle will enter
Aero Mode, regardless of vehicle speed if
the vehicle is in “SPORT” mode.
•Entry/Exit Mode (Lowers the vehicle approxi-
mately 1.6 inches (40 mm)– This position
lowers the vehicle for easier passenger en-
try and exit as well as lowering the rear of
the vehicle for easier loading and unloading
of cargo. To enter Entry/Exit Mode, push 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. If the vehicle speed remains between15 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
Entry/Exit Mode change will be cancelled.
To exit Entry/Exit Mode, press the “Up”
button once while in Entry/Exit Mode or
drive the vehicle over 15 mph (24 km/h).
NOTE:
Automatic lowering of the vehicle into Entry/
Exit Mode can be enabled through the
Uconnect Touch-Screen Radio. If this feature
is enabled, the vehicle will only lower if the
gear selector is in "PARK", the terrain switch
is in "AUTO", the transfer-case is in "AUTO”
and the vehicle level should be either in
Normal or Aero Mode. The Vehicle will not
automatically lower if the air suspension level
is in Off Rd 2 or Off Rd 1. If the vehicle is
equipped with Intrusion Theft Module (ITM),
the lowering will be suppressed when the
ignition is switched OFF and the door is open
to prevent setting the alarm off.
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
STARTING AND OPERATING
164

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 ac-
celeration over two-wheel drive vehicles. If
equipped with air suspension, the level will
change to Normal Ride Height (NRH).
•Sand– Off road calibration for use on low
traction surfaces such as sand or wet grass.
Driveline is maximized for traction. Some
binding may be felt on less forgiving sur-
faces. The electronic brake controls are set
to limit traction control management of
throttle and wheel spin. If equipped with
air suspension, the default ride height for
Sand is Normal Ride Height (NRH).
•Mud– Off road calibration for use on low
traction surfaces such as mud. Driveline is
maximized for traction. Some binding may
be felt on less forgiving surfaces. The elec-
tronic brake controls are set to limit trac-tion 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 im-
proved ground clearance. Traction based
tuning with improved steer-ability for use
on high traction off-road surfaces. Use for
low speed obstacles such as large rocks,
deep ruts, etc. If equipped with air suspen-
sion, 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.
NOTE:
Activate the Hill Descent Control or Selec
Speed Control for steep downhill control. See
“Electronic Brake Control System” in this
section for further information.Instrument Cluster Display Messages
When the appropriate conditions exist, a
message will appear in the instrument clus-
ter. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.

sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
WARNING!
Do not use Summer tires in snow/ice con-
ditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can
be identified by a “mountain/snowflake”
symbol on the tire sidewall.
If you need snow tires,
select tires equivalent
in size and type to the
original equipment
tires. Use snow tires
only in sets of four;
failure to do so may
adversely affect the
safety and handling of your vehicle.Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at sus-
tained speeds over 75 mph (120 km/h). For
speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire
dealer for recommended safe operating
speeds, loading and cold tire inflation pres-
sures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of non-
studded tires. Some states prohibit studded
tires; therefore, local laws should be checked
before using these tire types.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “In Case Of Emergency” in
the Owner’s Manual for further information.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an auto-
matic car wash with a compact or limited
use temporary spare installed. Damage to
the vehicle may result.
Refer to the “Towing Requirements - Tires” in
“Starting And Operating” in the Owner’s
Manual for restrictions when towing with a
spare tire designated for temporary emer-
gency use.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare
tire and wheel equivalent in look and func-
tion to the original equipment tire and wheel
found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rota-
tion for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for
the recommended tire rotation pattern.SERVICING AND MAINTENANCE

Minimum Ground Clearance (Reference A)
The clearance value is measured next to the
lower edge of the differential. This value also
defines those for the “Approach Angle” the
“Departure Angle” and the “Breakover
Angle”.
Dimensions are expressed in inches (mm)
and refer to the vehicle equipped with its
original tires.Approach Angle (Reference B)
The approach angle is determined by the
horizontal line of the road surface, and by the
tangent line passing between the front wheel,
and the most projecting low point of the car.
The wider the angle, the lower the chance to
hit an obstacle with the body or chassis, when
climbing a steep slope or overcoming an
obstacle.Departure Angle (Reference C)
The departure angle is determined by the
same lines of the “Approach Angle”, and
refers to the rear part of the vehicle.
Breakover Angle (Reference D)
The value of the “Breakover Angle” is linked
to the ground clearance of the vehicle and
indicates the attitude of the vehicle to over-
come a wedge, more or less steep, preventing
279

the vehicle from resting on the ground with
the body or chassis after touching the wedge
with its lowest and most projecting parts
(usually the underbody), because this would
highly reduce wheel grip.
The wheels, without a suitable grip to the
ground, will not have sufficient hold to move
the vehicle, and will surge.
The higher the ground clearance, the wider
the breakover angle. Always bear in mind that
the higher the ground clearance, the lower
the stability, due to a higher center of gravity
which reduces the side rollover angle.WHEELS
Refer to the Tire Placard label located on the
door sill of the vehicle or to the Registration
Document for the tire size and pressure.

nance” for further information.
