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.

WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedi-
cated message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive and/or alternative
to the information contained in the Owner’s
Manual, which you are advised to read care-
fully in all cases. Always refer to the informa-
tion in this chapter in the event of a failure
indication. All active telltales will display first
if applicable. The system check menu may
appear different based upon equipment op-
tions and current vehicle status. Some tell-
tales are optional and may not appear.
Red Warning Lights
— Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four
to eight seconds as a bulb check when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position. This light will illuminate with a
single chime when a fault with the air bag has
been detected, it will stay on until the fault is
cleared. If the light is either not on during
startup, stays on, or turns on while driving,
have the system inspected at an authorized
dealer as soon as possible.
— Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake light
turns on it may indicate that the parking
brake is applied, that the brake fluid level is
low, or that there is a problem with the
anti-lock brake system.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
73

If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
four seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized dealer.The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
— Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Con-
tact an authorized dealer as soon as possible.
This indicates a possible problem with the
electrical system or a related component.
— Door Open Warning Light
This indicator will illuminate when a door is
ajar/open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a
single chime.
— Electric Power Steering Fault
Warning Light
This warning light will turn on when there's a
fault with the EPS (Electric Power Steering)
system. Refer to “Power Steering” in “Start-
ing And Operating” in the Owner’s Manual for
further information.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.
— Electronic Throttle Control (ETC)
Warning Light
This warning light will illuminate to indicate
a problem with the Electronic Throttle Con-
trol (ETC) system. If a problem is detected
while the vehicle is running, the light will
either stay on or flash depending on the
nature of the problem. Cycle the ignition
when the vehicle is safely and completely
stopped and the transmission is placed in the
PARK position. The light should turn off. If

ACC/ON/RUN position and if the driver’s seat
belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver
or front passenger seat belt remains unbuck-
led, the Seat Belt Reminder Light will flash or
remain on continuously and a chime will
sound.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
— Transmission Temperature Warning
Light — If Equipped
This warning light will illuminate to warn of a
high transmission fluid temperature. This
may occur with strenuous usage such as
trailer towing. If this light turns on, stop the
vehicle and run the engine at idle or slightly
faster, with the transmission in PARK or
NEUTRAL, until the light turns off. Once the
light turns off, you may continue to drive
normally.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning
Light is illuminated you could cause the
fluid to boil over, come in contact with hot
engine or exhaust components and cause
a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.
— Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
Yellow Warning Lights
— Service Adaptive Cruise Control
Warning Light
This light will turn on when the ACC system is
not operating and needs service. For further
information, refer to “Adaptive Cruise Control
(ACC)” in “Starting And Operating.”
— Anti-Lock Brake (ABS) Warning
Light
This warning light monitors the Anti-Lock
Brake System (ABS). The light will turn on
when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and may stay on for as
long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the
brake system is not functioning and service is
required as soon as possible. However, the
conventional brake system will continue to
operate normally, assuming the Brake Warn-
ing Light is not also on.

This warning light will indicate when the
Electronic Stability Control system is Active.
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN posi-
tion, and when ESC is activated. It should go
out with the engine running. If the “ESC
Indicator Light” comes on continuously withthe engine running, a malfunction has been
detected in the ESC system. If this warning
light remains on after several ignition cycles,
and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see an authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
• The “ESC Off Indicator Light” and the
“ESC Indicator Light” come on momen-
tarily each time the ignition is placed in the
ON/RUN or ACC/ON/RUN position.
• The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive.
• This light will come on when the vehicle is
in an ESC event.— Service LaneSense Warning Light

SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to en-
sure that the ABS is working properly each
time the vehicle is started and driven. During
this self-check, you may hear a slight clicking
sound as well as some related motor noises.
ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow,
gravel, bumps, railroad tracks, loose debris,
or panic stops may increase the likelihood of
ABS activation(s).
You also may experience the following when
ABS activates:
• The ABS motor noise (it may continue to
run for a short time after the stop).
• The clicking sound of solenoid valves.• Brake pedal pulsations.
• A slight drop of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated elec-
tronic equipment that may be suscep-
tible to interference caused by improp-
erly installed or high output radio
transmitting equipment. This interfer-
ence can cause possible loss of anti-lock
braking capability. Installation of such
equipment should be performed by
qualified professionals.
• Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may
lead to a collision. Pumping makes the
stopping distance longer. Just press
firmly on your brake pedal when you
need to slow down or stop.
• The ABS cannot prevent the natural laws
of physics from acting on the vehicle,
nor can it increase braking or steering
efficiency beyond that afforded by the
WARNING!
condition of the vehicle brakes and tires
or the traction afforded.
• The ABS cannot prevent collisions, in-
cluding those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
• The capabilities of an ABS equipped
vehicle must never be exploited in a
reckless or dangerous manner that could
jeopardize the user’s safety or the safety
of others.
ABS is designed to function with the OEM
tires. Modification may result in degraded
ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light”
will turn on when the ignition is turned to the
ON/RUN mode and may stay on for as long as
four seconds.
If the “Anti-Lock Brake Warning Light” re-
mains on or comes on while driving, it indi-
cates that the anti-lock portion of the brake
system is not functioning and that service is
SAFETY
86

required. However, the conventional brake
system will continue to operate normally if
the “Anti-Lock Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on,
the brake system should be serviced as soon
as possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning
Light” does not come on when the ignition is
turned to the ON/RUN mode, have the light
repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced
Electronic Brake Control system (EBC). This
system includes Electronic Brake Force Dis-
tribution (EBD), Anti-Lock Brake System
(ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Elec-
tronic Roll Mitigation (ERM). These systems
work together to enhance both vehicle stabil-
ity and control in various driving conditions.Your vehicle may also be equipped with
Trailer Sway Control (TSC), Ready Alert Brak-
ing (RAB), Rain Brake Support (RBS), Dy-
namic Steering Torque (DST), Hill Descent
Control (HDC), and Selec-Speed Control
(SSC).
Your vehicle may also be equipped with
Trailer Sway Control (TSC), Ready Alert Brak-
ing (RAB), Rain Brake Support (RBS), and-
Dynamic Steering Torque (DST).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the
braking torque between the front and rear
axles by limiting braking pressure to the rear
axle. This is done to prevent overslip of the
rear wheels to avoid vehicle instability, and to
prevent the rear axle from entering ABS be-
fore the front axle.
Brake System Warning Light
The red “Brake System Warning Light” will
turn on when the ignition is turned to the
ON/RUN mode and may stay on for as long as
four seconds.If the “Brake System Warning Light” remains
on or comes on while driving, it indicates that
the brake system is not functioning properly
and that immediate service is required. If the
“Brake System Warning Light” does not
come on when the ignition is turned to the
ON/RUN mode, have the light repaired as
soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emer-
gency braking situation by sensing the rate
and amount of brake application and then
applies optimum pressure to the brakes. This
can help reduce braking distances. The BAS
complements the anti-lock brake system
(ABS). Applying the brakes very quickly re-
sults in the best BAS assistance. To receive
the benefit of the system, you must apply
continuous braking pressure during the stop-
ping sequence, (do not “pump” the brakes).
Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake
pedal is released, the BAS is deactivated.

Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags
(SABs) (If Equipped)
Your vehicle may be equipped with Supple-
mental Seat-Mounted Side Air Bags (SABs).
If your vehicle is equipped with Supplemen-
tal Seat-Mounted Side Air Bags (SABs),
please refer to the information below.
Supplemental Seat-Mounted Side Air Bags
(SABs) are located in the outboard side of the
front seats. The SABs are marked with “SRS
AIRBAG” or “AIRBAG” on a label or on the
seat trim on the outboard side of the seats.
The SABs (if equipped with SABs) may help
to reduce the risk of occupant injury during
certain side impacts, in addition to the injury
reduction potential provided by the seat belts
and body structure.
When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim
cover. The inflating SAB deploys through the
seat seam into the space between the occu-
pant and the door. The SAB moves at a veryhigh speed and with such a high force that it
could injure occupants if they are not seated
properly, or if items are positioned in the area
where the SAB inflates. Children are at an
even greater risk of injury from a deploying air
bag.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air
Bags; the performance could be adversely
affected and/or objects could be pushed
into you, causing serious injury.
Supplemental Side Air Bag Inflatable Curtains
(SABICs) (If Equipped)
Your vehicle may be equipped with Supple-
mental Side Air Bag Inflatable Curtains
(SABICs). If your vehicle is equipped with
Supplemental Side Air Bag Inflatable Cur-
tains (SABICs), please refer to the informa-
tion below.
Supplemental Side Air Bag Inflatable Cur-
tains (SABICs) are located above the side
windows. The trim covering the SABICs is
labeled “SRS AIRBAG” or “AIRBAG.”
