activated. These features will stay on through the duration
of Remote Start or until the ignition switch is placed in the
ON/RUN mode.

and deactivated through the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” for further informa-
tion on Remote Start Comfort System operation.
General Information
The following regulatory statement applies to all radio
frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and
with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, in- cluding interference that may cause undesired opera-
tion.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
SENTRY KEY
The Sentry Key Immobilizer System prevents unauthor-
ized 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, an Ignition Node Module,
Keyless Push Button Ignition and a 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 will not allow the engine to
crank if an invalid key fob is used to start and operate the
vehicle. The system will shut the engine off in two seconds
if an invalid key fob is used to start the engine.
NOTE: A key fob that has not been programmed is also
considered an invalid key.
During normal operation, after placing the keyless 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 used
3
GETTING TO KNOW YOUR VEHICLE 33

an invalid key fob to try to start the engine. Either of these
conditions will result in the engine being 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.
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.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Customer Key Programming
Programming key fobs may be performed at an authorized
dealer.
Replacement Keys
NOTE: 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.
CAUTION!
• 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.
NOTE: 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.
When having the Sentry Key Immobilizer System serviced,
bring all vehicle keys with you to an authorized dealer.

VEHICLE SECURITY ALARM
The vehicle security alarm monitors the vehicle doors and
ignition for unauthorized operation. When the vehicle
security alarm is activated, interior switches for door locks
are disabled. The system provides both audible and visible
signals for the first three minutes. The horn will sound, the
headlights will turn on, the park lamps and/or turn signals
will flash and vehicle security light will flash repeatedly. For an additional 15 minutes only, the headlights will turn
on, the park lamps and/or turn signals, and vehicle
security light will flash.
To Arm The System
Follow these steps to arm the vehicle security alarm:
1. Remove the key from the ignition system (refer to
Starting The Engine inStarting And Operating for
further information).
• For vehicles equipped with Keyless Enter-N-Go —
Ignition, make sure the vehicle ignition system is
OFF.
• For vehicles not equipped with Keyless Enter-N-Go —
Ignition, make sure the vehicle ignition system is
OFF and the key is physically removed from the
ignition.
2. Perform one of the following methods to lock the vehicle:
• Push 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 same3
GETTING TO KNOW YOUR VEHICLE 35

exterior zone (refer toKeyless Enter- N-Go — Passive
Entry inGetting To Know Your Vehicle for further
information).
• Push the lock button on the key fob.
3. If any doors are open, close them.
The vehicle security alarm will set when you use the power
door locks, or use the key fob to lock the doors. After all the
doors are locked and closed, the vehicle security light, in
the instrument panel cluster, will flash rapidly for about 16
seconds to indicate that the alarm is being set. After the
alarm is set, the vehicle security light will flash at a slower
rate to indicate that the system is armed.
To Disarm The System
The vehicle security alarm can be disarmed using any of
the following methods:
1. Push the unlock button on the key fob.
2. Grasp the Passive Entry Unlock Door Handle with a valid key fob within 5 ft (1.5 m) of the passive entry door
handle. If equipped, refer to Keyless Enter-N-Go —
Passive Entry inGetting To Know Your Vehicle for
further information. 3. Cycle the ignition out of the OFF position.
•For vehicles equipped with Keyless Enter-N-Go —
Ignition, push the Keyless Ignition START/STOP but-
ton (requires at least one valid key fob in the vehicle).
• For vehicles not equipped with Keyless Enter-N-Go,
insert a valid key into the ignition switch and turn the
key to the ON position.
The vehicle security alarm is designed to protect your
vehicle. However, you can create conditions where the
system will give you a false alarm. If one of the previously
described arming sequences has occurred, the vehicle
security alarm will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle and open a
door, the alarm will sound. If this occurs, disarm the
vehicle security alarm.
If the vehicle security alarm is armed and the battery
becomes disconnected, the vehicle security alarm will
remain armed when the battery is reconnected; the exterior
lights will flash, and the horn will sound. If this occurs,
disarm the vehicle security alarm.

tion which initiated the alarm is still present, the system
will ignore that condition and monitor the remaining doors
and ignition.
