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.
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 autho -
rized 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
Úpage 381.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
If applicable, refer to the “Hybrid Supplement” for
additional information.
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, ACC, RUN, and START.
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.
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.

the steps from the beginning.
PROGRAMMING HOMELINK® TO A
M
ISCELLANEOUS DEVICE
The procedure on how to program HomeLink® to a
miscellaneous device follows the same procedure as
programming to a garage door opener
Úpage 48. Be sure
to determine if the device has a rolling code, or non-rolling
code before beginning the programming process.
NOTE:Canadian radio frequency laws require transmitter signals
to time-out (or quit) after several seconds of transmission,
which may not be long enough for HomeLink® to pick up
the signal during programming. Similar to this Canadian
law, some US gate operators are designed to time-out in
the same manner. The procedure may need to be
performed multiple times to successfully pair the device to
your HomeLink® buttons.
WARNING!
 Your motorized door or gate will open and close while
you are programming the universal transceiver. Do
not program the transceiver if people or pets are in
the path of the door or gate.
 Do not run your vehicle in a closed garage or
confined area while programming the transceiver.
Exhaust gas from your vehicle contains Carbon
Monoxide (CO) which is odorless and colorless.
Carbon Monoxide is poisonous when inhaled and
can cause you and others to be severely injured or
killed.

AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — IF EQUIPPED
The Automatic High Beam Headlamp Control system
provides increased forward lighting at night by
automatically controlling the high beams through the use
of a camera mounted on the vehicle’s header. This
camera detects vehicle specific light and automatically
switches from high beams to low beams until the
approaching vehicle is out of view.

 The Automatic High Beam Headlamp Control can be
turned on or off by selecting “ON” under “Auto High
Beam” within your Uconnect Settings
Úpage 184, as
well as turning the headlight switch to the AUTO posi -
tion and placing the multifunction lever in the high
beam position.
 Broken, muddy, or obstructed headlights and taillights
of vehicles in the field of view will cause headlights to
remain on longer (closer to the vehicle). Also, dirt, film,
and other obstructions on the windshield or camera
lens will cause the system to function improperly.
FLASH-TO-PASS
You can signal another vehicle with your headlights by
lightly pulling the multifunction lever toward you. This will
cause the high beam headlights to turn on, and remain on,
until the lever is released.
AUTOMATIC HEADLIGHTS — IF EQUIPPED
This system automatically turns the headlights on or off
according to ambient light levels. To turn the system on,
rotate the headlight switch clockwise to the last detent for
automatic headlight operation. When the system is on, the
headlight time delay feature is also on. This means the
headlights will stay on for up to 90 seconds after you place
the ignition into the OFF position. To turn the automatic
system off, move the headlight switch out of the AUTO
position.
NOTE:The engine must be running before the headlights will
come on in the automatic mode.
