Key-In-Ignition ReminderOpening the driver’s door when the Key Fob is
in the ignition and the ignition switch position is
OFF or ACC, sounds a signal to remind you to
remove the Key Fob.
NOTE:
The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or
ACC ignition position.
With the Keyless Enter-N-Go feature, opening
the driver’s door when the vehicle’s ignition
switch is placed in ACC or ON/RUN (engine
stopped) will cause the reminder chime to
sound. Refer to “Starting Procedures” in “Start-
ing And Operating” for further information.
SENTRY KEYThe 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 the factory-mated Key Fob
with Remote Keyless Entry (RKE) transmitter
and Wireless Ignition Node (WIN) 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 shut the engine off in two
seconds if an invalid Key Fob is used to start
the engine.
After turning the ignition switch to 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 an
invalid Key Fob 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 after-market 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.
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 pro-
grammed to any other vehicle.
CAUTION!
• Always remove the Key Fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.

CAUTION!(Continued)
• With Keyless Enter-N-Go, always remem-
ber to place the ignition in OFF.
At the time of purchase, the original owner is
provided with a four-digit Personal Identifica-
tion Number (PIN). Keep the PIN in a secure
location. This number is required for authorized
dealer replacement of Key Fobs. Duplication of
Key Fobs may be performed at an authorized
dealer.
NOTE:
When having the Sentry Key Immobilizer
system serviced, bring all vehicle ignition
keys with you to an authorized dealer.
Customer Key ProgrammingProgramming Key Fobs or RKE transmitters
may be performed at an authorized dealer.

VEHICLE SECURITY ALARM —
IF EQUIPPED
The Vehicle Security Alarm monitors the hood,
liftgate, liftgate flipper glass, vehicle doors for
unauthorized entry, and the ignition switch for
unauthorized operation. If something triggers
the alarm, the Vehicle Security Alarm will pre-
vent the vehicle from starting and provide the
following audio and visual signals: the horn will
pulse, the headlights will flash, the park lights
will flash, and the Vehicle Security Light in the
instrument cluster will flash.
To Arm the System
Vehicles Not Equipped with Keyless
Enter-N-Go
Remove the key from the ignition switch and
either press a power door lock switch while the
driver or passenger door is open, or press the
LOCK button on the Remote Keyless Entry
(RKE) transmitter. After the last door is closed,
or if all doors are closed, the Vehicle Security
Alarm will arm itself in about 16 seconds.
During that time, the Vehicle Security Light will
flash. If it does not illuminate, the Vehicle Secu-
rity Alarm is not arming. Also, if you open a door
during the arming period, the Vehicle Security
Alarm will cancel the arming process. If you
wish to rearm the Vehicle Security Alarm after
closing the door, you must repeat one of the
previously-described arming sequences.
Vehicles Equipped with Keyless
Enter-N-Go
Press the Keyless Enter-N-Go Start/Stop button
until the Electronic Vehicle Information Center
(EVIC) indicates that the vehicle ignition is
“OFF” (refer to “Starting Procedures” in “Start-
ing And Operating” for further information).

while the driver or passenger door is open,
press the lock button on the front driver or
passenger door handle with a valid key fob in
range, or press the Remote Keyless Entry
(RKE) transmitter LOCK button (refer to “Pas-
sive Entry System” in “Things To Know Before
Starting Your Vehicle” for further information).
To Disarm the System
Vehicles Not Equipped with Keyless
Enter-N-Go
Either press the UNLOCK button on the RKE
transmitter, or insert a valid ignition key into the
ignition switch, and turn the key to the ON/RUN
position.
NOTE:
•The driver’s door key cylinder cannot arm
or disarm the Vehicle Security Alarm.
• When the Vehicle Security Alarm is
armed, the interior power door lock
switches will not unlock the doors. Vehicles Equipped with Keyless
Enter-N-Go
Either press the UNLOCK button on the RKE
transmitter, pull on the front driver or passenger
door handle (refer to “Passive Entry System” in
“Things To Know Before Starting Your Vehicle”

Stop button (requires at least one valid Key Fob
in the vehicle), or insert a valid Key Fob into the
ignition switch (if the Start/Stop button is re-
moved) and rotate it to the ON/RUN position.
The Vehicle Security Alarm is designed to pro-
tect your vehicle; however, you can create
conditions where the Vehicle Security Alarm 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, the horn will sound, and the ignition will
not start the vehicle. If this occurs, disarm the
Vehicle Security Alarm.
ILLUMINATED ENTRYThe interior lights come on when you open any
door or use the Remote Keyless Entry (RKE)
transmitter to unlock any door. They will remain
on for approximately 30 seconds after all doors
are closed then fade to off.
The lights also will fade to off if you turn on the
ignition after you close all the doors. Refer to
“Electronic Vehicle Information Center (EVIC)/
Personal Settings (Customer-Programmable
Features)” in “Understanding Your Instrument
Panel” for further information.
NOTE:

DOOR LOCKSThe power door locks can be manually locked
or unlocked from inside the vehicle by using the
door lock knob. If the lock knob is down when
the door is closed, the door will lock. Therefore,
make sure the key is not inside the vehicle
before closing the door.WARNING!
•For personal security and safety in the
event of an accident, lock the vehicle doors
when you drive, as well as when you park
and leave the vehicle.
• When leaving the vehicle, always remove
the key from the ignition and lock your
vehicle. Do not leave unattended children
in the vehicle, or with access to an un-
locked vehicle. Unsupervised use of ve-
hicle equipment may cause severe per-
sonal injuries and death.

adjusting the belt to the desired length to
restrain a child seat or secure a large item in
a seat — if equipped
If you will be carrying children too small for
adult-sized seat belts, the seat belts or the
ISOFIX feature also can be used to hold infant
and child restraint systems. Refer to ISOFIX —
Child Seat Anchorage System for more infor-
mation.
NOTE:
The Advanced Front Airbags have a multi-
stage inflator design. This allows the airbag
to have different rates of inflation based on
the severity and type of collision.
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passen-
gers as safe as possible.
WARNING!
In an accident, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the interior
of your vehicle or other passengers, or you
can be thrown out of the vehicle. Always be
sure you and others in your vehicle are buck-
led up properly.
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and cause an
accident that includes you. This can happen far
away from home or on your own street.
Research has shown that seat belts save lives,
and they can reduce the seriousness of injuries
in an accident. Some of the worst injuries
happen when people are thrown from the ve-
hicle. Seat belts reduce the possibility of ejec-
tion and the risk of injury caused by striking the
inside of the vehicle. Everyone in a motor
vehicle should be belted at all times.Lap/Shoulder BeltsAll seating positions in your vehicle are
equipped with lap/shoulder belts. The belt
webbing retractor is designed to lock during
very sudden stops or accidents. This feature
allows the shoulder part of the belt to move
freely with you under normal conditions. How-
ever, in an accident the belt will lock and
reduce the risk of you striking the inside of the
vehicle or being thrown out.
WARNING!
•Wearing a seat belt incorrectly is dangerous.
Seat belts are designed to go around the
large bones of your body. These are the
strongest parts of your body and can take the
forces of an accident the best. Wearing your
belt in the wrong place could make your
injuries in an accident much worse. You
might suffer internal injuries, or you could
even slide out of part of the belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.

This safety belt system has a retractor assem-
bly that is designed to release webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the occu-
pant’s chest.
WARNING!
•The belt and retractor assembly must be
replaced if the seat belt assembly Auto-
matic Locking Retractor (ALR) feature or
any other seat belt function is not working
properly when checked according to the
procedures in the Service Manual.
• Failure to replace the belt and retractor
assembly could increase the risk of injury in
accidents.
Automatic Locking Retractors (ALR)
Mode — If Equipped
In this mode, the shoulder belt is automatically
pre-locked. The belt will still retract to remove
any slack in the shoulder belt. The Automatic
Locking Mode is available on all passenger-
seating positions with a combination lap/
shoulder belt. When To Use The Automatic Locking Mode
Use the Automatic Locking Mode anytime a
child safety seat is installed in a seating posi-
tion that has a belt with this feature. Children
12 years old and under should always be
properly restrained in the rear seat.
How To Engage The Automatic Locking
Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire belt is extracted.
3. Allow the belt to retract. As the belt retracts,
you will hear a clicking sound. This indicates
the safety belt is now in the Automatic Locking
Mode.
How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.
Seat Belts In Passenger Seating
Positions
The seat belts in the passenger seating posi-
tions are equipped with Automatic Locking
Retractors (ALR) which are used to secure a
child restraint system. For additional informa-
tion refer to “Installing Child Restraints Using
the Vehicle Seat Belt” under the “Child Re-
straints” section. The chart below defines the
type of feature for each seating position.

NOTE:
•If you have difficulties or problems reset-
ting the Active Head Restraints, see an
authorized dealer.
• For safety reasons, have the Active Head
Restraints checked by a qualified special-
ist at an authorized dealer.Enhanced Seat Belt Use Reminder
System (BeltAlert )
BeltAlert is a feature intended to remind the
driver and front passenger (if equipped with
front passenger BeltAlert ) to fasten their seat-
belts. This feature is active whenever the igni-
tion is on. If the driver or front seat passenger is
unbelted, the Seat Belt Reminder Light will turn
on and remain on until both front seatbelts are
fastened. BeltAlert triggers within 60 seconds
of vehicle speed over 5 mph (8 km/h). The
reminder sequence lasts for 96 seconds or until
the respective seatbelts are fastened. After the
sequence completes, the Seat Belt Reminder
Light remains illuminated until front belts are
fastened. The driver should instruct all other
occupants to fasten their seatbelts. If a front
seatbelt is unbuckled while traveling at speeds
greater than 5 mph (8 km/h), BeltAlert will
chime as a single notification and illuminate the
Seat Belt Reminder Light, then will proceed to
the 96 second reminder sequence.
The front passenger seat BeltAlert is not ac-
tive when the front passenger seat is unoccu-
pied. BeltAlert may be triggered when an
animal or heavy object is on the front passen- ger seat or when the seat is folded flat (if
equipped). It is recommended that pets be
restrained in the rear seat in pet harnesses or
pet carriers that are secured by seat belts, and
cargo is properly stowed.
NOTE:
•
BeltAlert can be enabled or disabled by
your authorized dealer.
• Chrysler Group LLC does not recommend
deactivating BeltAlert .
Although BeltAlert has been deactivated,
the Seat Belt Reminder Light will continue to
illuminate while the driver seat belt remains
unfastened.
Seatbelt Lock OutThe center rear seat belt system has a lock out
feature that will not allow you to extract the
center webbing unless the rear seat upper
latch is engaged.
Seat Belts and Pregnant WomenWe recommend that pregnant women use the
seat belts throughout their pregnancy. Keeping
the mother safe is the best way to keep the
baby safe.
