SYMBOLS KEY
If you do not read the entire Owner’s Manual, you may miss important
information. Observe all Cautions and Warnings.
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 out of control. Because of the higher center of gravity, if this vehicle is
out of control it may roll over while some other vehicles may not.
Do not attempt sharp turns, abrupt maneuvers, 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 fact, the US government notes that the universal use
of existing seat belts could cut the highway death toll by 10,000 or more each
year and could reduce disabling injuries by two million annually. In a rollover
crash, an unbelted person is significantly more likely to die than a person
wearing a seat belt. Always buckle up.
WARNING!
These statements apply to operating procedures
that could result in a collision, bodily injury and/or
death.
CAUTION! These statements apply to procedures that could
result in damage to your vehicle.
NOTE: A suggestion which will improve installation,
operation, and reliability. If not followed, may
result in damage.
TIP: General ideas/solutions/suggestions on easier
use of the product or functionality.

GETTING TO KNOW YOUR VEHICLE
KEYS
KEY FOB

Your vehicle is equipped with a key fob which
supports Passive Entry, Remote Keyless Entry
(RKE), Keyless Enter ‘n Go™ (if equipped), and
Remote Start (if equipped). The key fob allows you to
lock or unlock the doors and tailgate 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. The key fob also contains a mechanical key.

NOTE:
The key fob’s wireless signal may be blocked if
the key fob is located next to a mobile phone,
laptop, or other electronic device. This may
result in poor performance.
With the ignition in the ON/RUN position, and
the vehicle moving at 2 mph (4 km/h), all RKE commands are disabled.

Key Fob

NOTE:
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
condition may be indicated 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 illu-
minates from key fob button pushes, then the
key fob battery requires replacement.
Improper disposal of key fob batteries may be
harmful to the environment. Please see an
authorized dealer for proper battery disposal
Ú page 432.
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 effectiveness of the electronic devices
inside of the key fob, avoid exposing the key fob
to direct sunlight.

To Lock/Unlock The Doors And Tailgate
Push and release the unlock button on the key fob
once to unlock the driver’s door, or twice to unlock
all the doors. To lock all the doors, push the lock
button once.
When the doors are unlocked, the turn signals will
flash and the illuminated entry system will be
activated. When the doors are locked, the turn
signals will flash and the horn will chirp.
NOTE:
All doors can be programmed to unlock on the
first push of the unlock button through
Uconnect Settings Úpage 215.
The mechanical flip key can be used to lock or
unlock the doors, tailgate, glove compartment,
storage compartments (if equipped), and rear
seatbacks.
Key Left Vehicle Feature
If a valid key fob is no longer detected inside the
vehicle while the vehicle’s ignition system is in the
ON/RUN or START position, the message “Key Fob
Has Left The Vehicle” will be shown in the
instrument cluster display along with an interior
chime. An exterior audible and visual alert will also
be activated to warn the driver. The vehicle’s horn will rapidly chirp three times
along with a single flash of the vehicle’s exterior
lights.
NOTE:
The doors have to be open and then closed in
order for the vehicle to check for the presence of
a key fob; the Key Left Vehicle feature will not
activate until all of the doors are closed.
These alerts will not be activated in situations
where the vehicle’s engine is left running with
the key fob inside.
Replacing The Battery In The Key Fob
The recommended replacement battery is
CR2450.
NOTE:
Customers are recommended to use a battery
obtained from Mopar®. Aftermarket coin
battery dimensions may not meet the original
OEM coin battery dimensions.
Perchlorate material — special handling may
apply. See www.dtsc.ca.gov/hazardouswaste/
perchlorate for further information.
Do not touch the battery terminals that are on
the back housing or the printed circuit board.
When a key fob battery is low, a warning will be
indicated on the vehicle’s instrument cluster,
and the fob LED will no longer illuminate with a
button push.

1. Remove the back cover of the key fob by inserting a flat-blade screwdriver into the slot
on the bottom of the fob. Apply light pressure
until the cover unsnaps being careful not to
damage the seal. Proceed counterclockwise
(in the order shown in the following image) to
loosen the remaining snaps until the battery
cover can be removed.

GETTING TO KNOW YOUR VEHICLE17
2. Remove the depleted battery by inserting a small flat-blade screwdriver into the battery
removal slot and sliding the battery forward
and upward being careful not to damage the
electronic board underneath.

Battery Replacement

3. Install the new battery into the key fob, making sure the positive (+) side is facing up. Slide the
battery until it is seated securely below the
tabs.
4. Reassemble the back cover making sure it is properly aligned before snapping it back in
place.
Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be repurposed and reprogrammed to
another vehicle.
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.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed or
activated. Operation is automatic, regardless of
whether the vehicle is locked or unlocked.
WARNING!
The integrated key fob contains a coin cell
battery. Do not ingest the battery; there is a
chemical burn hazard. If the coin cell battery is
swallowed, it can cause severe internal burns
in just two hours and can lead to death.
If you think a battery may have been swal-
lowed or placed inside any part of the body,
seek immediate medical attention.
Keep new and used batteries away from chil
-
dren. If the battery compartment does not
close securely, stop using the product and
keep it away from children.
WARNING!
Always remove the key fobs from the vehicle
and lock all doors when leaving the vehicle
unattended.
Always remember to place the Keyless
Enter ‘n Go™ Ignition in the OFF position when
exiting the vehicle.2

23_JT_OM_EN_USC_t.book Page 17

18GETTING TO KNOW YOUR VEHICLE
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. Therefore,
only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The
system cannot reprogram a key fob obtained from
another vehicle.
After placing the ignition switch in the ON/RUN
position, the Vehicle Security Light will turn on for
three seconds for a bulb check. If the light remains
on after the bulb check, it indicates that there is a
problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates
that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob
is used to start the engine but there is an issue
with the vehicle electronics, the engine will start
and shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than
ten seconds), it indicates that there is a fault in the
electronics. Should this occur, have the vehicle
serviced as soon as possible by an authorized
dealer. All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics
Ú
page 432.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the
ignition switch with the push of a START/STOP
ignition button as long as the key fob is in the
passenger compartment.
The START/STOP ignition button has several
operating modes that are labeled and will
illuminate when in position. These modes are OFF,
ACC, RUN, and START.
START/STOP Ignition Button

The push button ignition can be placed in the
following modes:
OFF The engine is stopped.
Some electrical devices (e.g. power locks,
alarm, etc.) are available.
ACC
Engine is not started.
Some electrical devices are available (power
windows, etc.).
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.

GETTING TO KNOW YOUR VEHICLE19
RUN
Driving position.
All electrical devices are available.
START
The engine will start.
NOTE:In case the ignition switch does not change with
the push of the START/STOP ignition button, the
key fob may have a low or depleted battery. In this
situation, a backup method can be used to operate
the ignition switch. Put the nose side of the key fob
(side with the mechanical flip key) against the
START/STOP ignition button and push to operate
the ignition switch.
Backup Starting Method
Do Not Use Mechanical Key

CAUTION!
Do not press the mechanical key against the
START/STOP ignition button.
Do not use sharp metal objects (e.g. screw -

switch. This button comes as an assembly,
and is not removable. This can damage the
silicone shield.
WARNING!
When exiting the vehicle, always remove the
key fob from the vehicle and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
Allowing children to be in a vehicle unattended
is dangerous for a number of reasons. A child
or others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the Keyless Enter ‘n Go™ Ignition in
the ON/RUN position. A child could operate
power windows, other controls, or move the
vehicle.
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup
may cause serious injury or death.

23_JT_OM_EN_USC_t.book Page 19

20GETTING TO KNOW YOUR VEHICLE
NOTE:When opening the driver's door with the ignition in
the ON/RUN (engine not running) position, a chime
will sound to remind you to place the ignition in the
OFF position. In addition to the chime, the
message will display “Ignition Or Accessory On” in
the cluster.
REMOTE START — IF EQUIPPED
(GASOLINE)

This system uses the key fob to start the
engine conveniently from outside the
vehicle while still maintaining security.
The system has a range of 328 ft (100 m).

Remote Start is used to defrost windows in cold
weather, and to reach a comfortable climate in all
ambient conditions before the driver enters the
vehicle.
NOTE:
The vehicle must be equipped with an auto -
matic transmission to be equipped with Remote
Start.
Obstructions between the vehicle and key fob
may reduce this range Ú page 432.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The vehicle
doors and tailgate will lock, the turn signals will
flash twice, and the horn will chirp twice (if
equipped). Pushing the Remote Start button again
will shut the engine off.
NOTE:
With Remote Start, the engine will only run for
15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is low,
the vehicle will start and then shut down in
10 seconds.
The parking lights will turn on and remain on
during Remote Start mode.
For security, power window operation is
disabled when the vehicle is in the Remote Start
mode.
The ignition must be placed in the ON/RUN posi -
tion before the Remote Start sequence can be
repeated for a third cycle.
All of the following conditions must be met before
the engine will remote start:
Gear selector in PARK
Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not pressed)
Battery at an acceptable charge level
Panic button not pushed
System not disabled from previous Remote
Start event
CAUTION!
An unlocked vehicle is an invitation for thieves.
Always remove key fob from the vehicle and lock
all doors when leaving the vehicle unattended.
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas contains
carbon monoxide (CO) which is odorless and
colorless. Carbon monoxide is poisonous and
can cause serious injury or death when
inhaled.
Keep key fobs away from children. Operation
of the Remote Start system, windows, door
locks or other controls could cause serious
injury or death.
