3. Remove the cap covering the key fob battery.
4. Insert the small flat-bladed tool into the gap next to the battery and pry the battery upward to remove.
5. 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
deterioration. If you touch a battery, clean it with
rubbing alcohol.

Key Fob Battery Replacement

6. Replace the battery cap, the reassemble the key fob case by snapping 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 elec -
tronics can be used to start and operate the 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 autho -
rized dealer.
 Keys must be ordered to the correct key cut to match
the vehicle locks.
 It is not mandatory to replace the key fob if a new emer -
gency key is needed, and vice versa.
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 swallowed 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 chil -
dren.
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™ Igni -
tion, always remember to place the ignition in the
OFF position when exiting the vehicle.

16GETTING TO KNOW YOUR VEHICLE
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
Úpage 275.
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 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.

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 still available.
ON/RUN
 Driving mode.
 All electrical devices are available (e.g., climate
controls, heated seats, etc.).
START
 The engine will 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.
1 — OFF
2 — ON/RUN

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 Úpage 275.
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 opera -
tion (if equipped) are disabled when the vehicle is in
the Remote Start mode.
 The ignition must be placed in the ON/RUN position
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 intrusion
 Malfunction Indicator Light is not illuminatedWARNING!
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.

REMOTE START ABORT MESSAGE —
I
F EQUIPPED
One of the following messages will display in the
instrument cluster display if the vehicle fails to remote
start or exits Remote Start prematurely:
 Remote Start Aborted — Door Open
 Remote Start Aborted — Hood Open
 Remote Start Aborted — Fuel Low

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. It also monitors movement inside
the passenger compartment (volumetric protection —
if equipped), cutting of battery cables, and unexpected
lifting/tilting of the vehicle (anti-lift protection —
if equipped). 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
NOTE:
The Vehicle Security system is activated by the Engine
Immobilizer system, which is automatically activated
when you get out of the vehicle with the key fob and
lock the doors.
 The Vehicle Security system is factory adjusted to stan -
dards from different countries.
 The Vehicle Security system is a complementary secu -
rity system developed to hinder the occurrence of
vehicle theft and prevent vandalism. It does not
prevent the theft of your vehicle; the system is a deter -
rent.
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 available in the
same exterior zone
Úpage 23.
 Push the lock button on the key fob.
3. If any doors (or liftgate) are open, close them.
When the Vehicle Security system is armed (except on
some versions for specific markets), the system will emit
an acoustic warning and a warning light (located next to
the interior door handle) will flash until it is disarmed.
NOTE:
 If there is a fault with the system, the system will emit
an acoustic signal a second time.
 If this occurs, wait about 4 seconds and switch off the
Vehicle Security system following this procedure:
a. Press the unlock button on the key fob.
b. Check that the doors, hood, and liftgate are closed, and then reactivate the system by pressing
the lock button.
 If the alarm emits a sound even when the doors, hood,
and liftgate are closed, there is a fault with the system.
Contact an authorized dealer for assistance.
 The vehicle doors can be locked without arming the
Vehicle Security system by using the emergency key in
the exterior door lock cylinder.
