GETTING TO KNOW YOUR VEHICLE21

Battery Removal Pocket

NOTE:When replacing the battery, ensure the (+) sign on
the battery is facing upward. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean
it with rubbing alcohol.
5. Replace the battery by using your thumb to push down and slide the battery under the
small lip on the top edge of the opening.
Key Fob Battery Replacement

6. To assemble the key fob case, line up the top edge of the back cover with the top of the fob,
and press the edges into the interlocking
hinges until all edges snap together with no
large visual gaps.
7. Reinsert the emergency key until it locks into place.
NOTE:The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer.
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 chil -
dren. If the battery compartment does not
close securely, stop using the product and
keep it away from children.

22GETTING TO KNOW YOUR 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. 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 408.
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 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,
ON/RUN, and START.
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.
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.

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 position
All electrical devices are available (e.g. climate
controls, heated seats, etc.) START
The engine will start (when foot is on the brake
pedal)
NOTE:
If the ignition position does not change with a
push of the ignition button, and the instrument
cluster displays a message such as “Key Fob
Not Detected”, 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
opposite of the emergency key) against the
START/STOP ignition button and push to
operate the ignition switch.
Replacement of the key fob battery is recom
-
mended.

Depleted Key Fob Battery Procedure

1 — OFF
2 — ON/RUN
WARNING!
When exiting the vehicle, always place the
ignition in the OFF position, 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 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.
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.

24GETTING TO KNOW YOUR VEHICLE
NOTE:
The key fob may not be detected by the vehicle
Keyless Enter ‘n Go™ system if it is located next
to a mobile phone, laptop or other electronic
device, or in the cupholders near aluminum
cans; these devices may block the key fob’s
wireless signal and prevent the Keyless Enter ‘n
Go™ system from starting the vehicle.
For more information on the engine starting
procedure, see Úpage 119.
When opening the driver's door and the ignition
is in the ON/RUN position (engine not running),
a chime will sound to remind you to place the
ignition in the OFF position. In addition to the
chime, the message “Ignition ON” will display in
the cluster.
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 driver enters the
vehicle.
NOTE:Obstructions between the vehicle and key fob may
reduce this range Ú page 408.
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.
NOTE:
If the Remote Start button on the key fob is
pushed too rapidly during activation, the vehicle
may not start.
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.
Headlight animation (if equipped) will occur
when Remote Start is activated, if “Headlight
Illumination On Approach” is enabled within
Uconnect Settings.
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.
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.
