WARNING: Operating, servicing and maintaining a passenger vehicle or off-highway
motor vehicle can expose you to chemicals including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the State of California to cause cancer and
birth defects or other reproductive harm. To minimize exposure, avoid breathing exhaust,
do not idle the engine except as necessary, service your vehicle in a well-ventilated area
and wear gloves or wash your hands frequently when servicing your vehicle. For more
information go to www.P65Warnings.ca.gov/passenger-vehicle.
The driver’s primary responsibility is the safe operation of the vehicle. Driving while distracted can result in loss of vehicle control, resulting in an accident
and personal injury. FCA US LLC strongly recommends that the driver use extreme caution when using any device or feature that may take their attention
off the road. Use of any electrical devices, such as cellular telephones, computers, portable radios, vehicle navigation or other devices by the driver while
the vehicle is moving is dangerous and could lead to a serious accident. Texting while driving is also dangerous and should never be done while the vehicle
is moving. If you find yourself unable to devote your full attention to vehicle operation, pull off the road to a safe location and stop your vehicle. Some states
or provinces prohibit the use of cellular telephones or texting while driving. It is always the driver’s responsibility to comply with all local laws.

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.

16GETTING TO KNOW YOUR VEHICLE
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

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.

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

142GETTING TO KNOW YOUR INSTRUMENT PANEL
If any of these systems require service, the OBD II
system will turn on the Malfunction Indicator Light
(MIL). It will also store diagnostic codes and other
information to assist your service technician in
making repairs. Although your vehicle will usually
be drivable and not need towing, see an authorized
dealer for service as soon as possible.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may need
to access this information to assist with the
diagnosis and service of your vehicle and
emissions system Ú page 214.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to
pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration. For states and/or provinces that require
an Inspection and Maintenance (I/M),
this check verifies the Malfunction
Indicator Light (MIL) is functioning and is
not on when the engine is running, and that the
OBD II system is ready for testing.
The OBD II system may not be ready if your vehicle
was recently serviced, recently had a depleted
battery or a battery replacement. If the OBD II
system should be determined not ready for the I/M
test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test,
which you can use prior to going to the test station.
To check if your vehicle's OBD II system is ready,
you must do the following:

1. Cycle the ignition switch to the ON position, but do not crank or start the engine.

NOTE:If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction
Indicator Light (MIL) symbol come on as part of
a normal bulb check.
CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection
port in order to read the VIN, diagnose, or
service your vehicle.
If unauthorized equipment is connected to the
OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

23_JT_OM_EN_USC_t.book Page 142

GETTING TO KNOW YOUR INSTRUMENT PANEL143
3. Approximately 15 seconds later, one of two things will happen:
The MIL will flash for about 10 seconds and
then return to being fully illuminated until
you turn OFF the ignition or start the engine.
This means that your vehicle's OBD II
system is not ready and you should not
proceed to the I/M station.
The MIL will not flash at all and will remain
fully illuminated until you place the ignition
in the off position or start the engine. This
means that your vehicle's OBD II system is
ready and you can proceed to the I/M
station. If your OBD II system is
not ready, you should see
an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do nothing
more than drive your vehicle as you normally would
in order for your OBD II system to update. A
recheck with the previously mentioned test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system
is ready, if the MIL is illuminated during normal
vehicle operation you should have your vehicle
serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL is on
with the engine running.3
