Essential Information
Consult the Table of Contents to determine
which section contains the information you
desire.
Since the specification of your vehicle
depends on the items of equipment ordered,
certain descriptions and illustrations may
differ from your vehicle's equipment.
The detailed Index at the back of this User
Guide contains a complete listing of all
subjects.
Symbols
Some vehicle components have colored
labels 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 clearanceand 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 out of 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
operate this vehicle safely may result in a
collision, rollover of the vehicle, and severe
or fatal injury. Drive carefully.
Rollover Warning Label

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.

WARNINGS AND CAUTIONS
This User Guide contains
WARNINGS against
operating procedures that could result in a
collision, bodily injury and/or death. It also
contains CAUTIONS against procedures that
could result in damage to your vehicle. If you
do not read this entire guide, you may miss

GETTING TO KNOW YOUR VEHICLE
KEYS
Key Fob
Key FobYour vehicle uses a keyless ignition system.
The ignition system consists of a key fob with
Keyless Go and a START/STOP push button
ignition system. The Remote Keyless Entry
(RKE) system consists of a key fob with a
mechanical key and Keyless Enter-N-Go
feature (if equipped).
NOTE:
The key fob may not be detected by the
vehicle if it is located next to a mobile phone,
laptop or other electronic device; these
devices may block the key fob’s wireless
signal.
The key fob allows you to lock or unlock the
doors and swing gate from distances up to
approximately 66 ft (20 m). The key fob
does not need to be pointed at the vehicle to
activate the system. NOTE:
With the ignition in the ON/RUN position
and with the vehicle doors open, the lock
button will be disabled, and only the unlock
button will be enabled. All RKE commands
will be disabled once the vehicle begins
moving at 2 mph (4 km/h) or above.
Backup Mode Starting
In case the ignition switch does not change
with the push of a button, the key fob may
have a low or fully depleted battery. A low key
fob battery can be verified by referring to the
instrument cluster, which will display direc
-
tions to follow.
NOTE:
A low key fob battery condition may be indi -
cated by a message in the instrument cluster
display, or by the LED light on the key fob. If
the LED key fob light no longer illuminates
from key fob button pushes, then the key fob
battery requires replacement.

WARNING!
Push the Mechanical Key Release Button
only with the key fob facing away from
your body, especially your eyes and objects
that may be damaged, such as clothing.
CAUTION!

The electrical components inside of the key
fob may be damaged if the key fob is
subjected to strong electrical shocks. In
order to ensure complete efficiency of the
electronic devices inside of the key fob,
avoid exposing the key fob to direct sunlight.

In this situation, a back up method can be used
to operate the ignition switch. Put the nose side
of the key fob against the START/STOP ignition
button, and push to operate the ignition switch.
Backup Starting Method
NOTE:
Improper disposal of key fob batteries may
be harmful to the environment. Please see an
authorized dealer for proper battery disposal.
To Unlock The Doors And Swing Gate
Push and release the key fob unlock button
once to unlock the driver's door only, or twice
to unlock all the doors and swing gate. When
the key fob unlock button is pushed, the Illu -
minated Entry will initiate, and the turn
signal lights will flash twice.
To Lock The Doors And Swing Gate
Push and release the lock button on the key
fob to lock all doors. The turn signals will
flash, and the horn will chirp once to
acknowledge the lock signal.
Request For Additional Key Fobs
NOTE:
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle.
Duplication of key fobs may be performed at
an authorized dealer. This procedure
consists of programming a blank key fob to
the vehicle electronics. A blank key fob is
one that has never been programmed. NOTE:
When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys
with you to an authorized dealer.
Keys must be ordered to the correct key
cut to match the vehicle locks.
IGNITION SWITCH
Keyless Enter-N-Go — Ignition
This feature allows the driver to operate the
ignition switch with the push of a button as
long as the key fob is in the passenger
compartment.
The Keyless Push Button Ignition has several
operating modes that are labeled and will
illuminate when in position. These modes
are OFF, ACC, RUN, and START.
NOTE:
In case the ignition switch does not change
with the push of a button, the key fob may
have a low or depleted battery. In this situa
-
tion, a back up method can be used to
operate the ignition switch. Put the nose side
of the key fob (side with the mechanical key)
against the START/STOP ignition button and
push to operate the ignition switch.
WARNING!
Always remove the key fobs from the
vehicle and lock all doors when leaving
the vehicle unattended.
Always remember to place the ignition in
the OFF mode.

panels should be closed to prevent wind,
leaves, and other debris from blowing into
the vehicle. Items left in the vehicle that may
shift over a period of time (e.g. plastic bags,
clothes, or groceries), could result in a
nuisance alarm. Additionally, extreme environmental condi
-
tions (wind, rain, hail, thunder, etc.), or
extreme noise (audio systems, traffic condi -
tions, trains, etc.), or direct impacts to the
vehicle may result in a nuisance alarming
condition.
If one of the previously described arming
sequences has occurred, the vehicle security
alarm will arm regardless of whether you are

vehicle and open a door, the alarm will
sound. If this occurs, disarm the vehicle
security alarm.
If the vehicle security alarm is armed and the
battery becomes disconnected, the vehicle
security alarm will remain armed when the
battery is reconnected; the exterior lights will
flash, the horn will sound. If this occurs,
disarm the vehicle security alarm.
Security System Manual Override
The system will not arm if you lock the doors
