2. Separate the key fob halves using a #2 flat blade screwdriver or a coin, and gently pry the
two halves of the key fob apart. Make sure not
to damage the seal during removal.

3. Remove the back cover to access and replace
the battery. When replacing the battery, match
the (+) sign on the battery to the (+) sign on the
inside of the battery clip, located on the back
cover. Avoid touching the new battery with your
fingers. Skin oils may cause battery deterio -
ration. If you touch a battery, clean it with
rubbing alcohol.
4. To assemble the key fob case, snap the two halves together.
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.
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
children. 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.
For vehicles equipped with Keyless
Enter ‘n Go™ Ignition, always remember to
place the ignition in the OFF position.

22_MP_OM_EN_USC_t.book Page 16

GETTING TO KNOW YOUR VEHICLE17
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.
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 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
10 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 328.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the
ignition with the push of a button as long as the
key fob is in the passenger compartment.
The START/STOP ignition button has three
operating modes. The three modes are OFF,
ON/RUN, and START.

CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket Remote Start
systems. Use of these systems may result in
vehicle starting problems and loss of security
protection.

REMOTE START — IF EQUIPPED
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 approximately
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 customer enters the
vehicle.
NOTE:Obstructions between the vehicle and key fob may
reduce this range Ú page 328.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The vehicle
doors will lock, the parking lights will flash, and the
horn will chirp twice (if programmed). Then, the
engine will start, and the vehicle will remain in the
Remote Start mode for a 15 minute cycle. Pushing
the Remote Start button a third time shuts the
engine off.
To drive the vehicle, push the unlock button and
place the ignition in the ON/RUN position.
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 and power sunroof
operation (if equipped) are 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
Liftgate 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
Vehicle Security Light flashing (if equipped)
Ignition in the OFF position
Fuel level meets minimum requirement
Vehicle Security system is not signaling an intru
-
sion
Malfunction Indicator Light is not illuminated
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.WARNING!

Do not start or run an engine in a closed garage

VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the vehicle
doors, hood, liftgate, and the Keyless Enter ‘n Go™
Ignition for unauthorized operation. While the
Vehicle Security system is armed, interior switches
for door locks and liftgate release are disabled. If
something triggers the system, the Vehicle Security
system will provide the following audible and
visible signals:
The horn will pulse
The turn signals will flash
The Vehicle Security Light in the instrument
cluster will flash
NOTE:
The Vehicle Security system is factory adjusted
to standards from different countries.
The Vehicle Security system is a complementary
security system developed to hinder the occur -
rence of vehicle theft and prevent vandalism. It
does not prevent the theft of your vehicle; the
system is a deterrent.
The Vehicle Security system does not monitor
glass breakage or the movement of objects or
people inside the vehicle. The alarm does not
intervene in the case of vehicle tilt variations
when it is parked.
TO ARM THE SYSTEM
Follow these steps to arm the Vehicle Security
system:

1. Make sure the vehicle’s ignition is placed in the OFF position.

For vehicles equipped with Keyless Entry,
make sure the vehicle’s keyless ignition
system is OFF.
2. Perform one of the following methods to lock the vehicle:
Push the lock button on the interior power
door lock switch with the driver and/or
passenger door open.
Push the lock button on the exterior Passive
Entry door handle with a valid key fob avail -
able in the same exterior zone Ú page 23.
Push the lock button on the key fob.
3. If any doors are open, close them.
When the Vehicle Security system is armed, the
Vehicle Security Light (located in the lower left
portion of the instrument cluster display) will begin
to flash every three seconds until it is disarmed.
