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 KeyImmobilizer 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.
(Continued)
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 provide the following audio
and visual signals: the horn will pulse, the
headlights will turn on, the park lights will flash,
and the Vehicle Security Light in the instrument
cluster will flash.
To Arm The SystemFollow these steps to arm the Vehicle Security
Alarm:
1. Remove the key from the ignition system
(refer to Starting Procedures inStarting And
Operating for further information).
• For vehicles equipped with Keyless Enter-N-
Go, make sure the vehicle ignition system is

NOTE:
•The driver’s door key cylinder and the
liftgate button on the RKE transmitter
cannot arm or disarm the Vehicle Security
Alarm.
• The Vehicle Security Alarm remains
armed during power liftgate entry. Press-
ing the liftgate button will not disarm the
Vehicle Security Alarm. If someone enters
the vehicle through the liftgate and opens
any door the alarm will sound.
• When the Vehicle Security Alarm is
armed, the interior power door lock
switches will not unlock the doors.
The Vehicle Security Alarm is designed to pro-
tect 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, the horn will sound. If this occurs, disarm
the Vehicle Security Alarm.
Tamper AlertIf something has triggered the Vehicle Security
Alarm in your absence, the horn will sound
three times and the exterior lights blink three
times when you unlock the doors. Check the
vehicle for tampering.
ILLUMINATED ENTRYThe courtesy lights will turn on when you use
the Remote Keyless Entry (RKE) transmitter to
unlock the doors or open any door.
This feature also turns on the approach lighting
in the outside mirrors (if equipped). Refer to
“Mirrors” in “Understanding The Features Of
Your Vehicle” for further information.
The lights will fade to off after approximately
30 seconds or they will immediately fade to off
once the ignition switch is turned to ON/RUN
from the OFF position.
NOTE:
•
The front courtesy overhead console and
door courtesy lights do not turn on if the
dimmer control is in the Dome ONposi-
tion (extreme top position).
• The Illuminated Entry system will not op-
erate if the dimmer control is in the
“Dome defeat” position (extreme bottom
position).REMOTE KEYLESS ENTRY (RKE)This system allows you to lock or unlock the
doors or liftgate from distances up to approxi-
mately 33 ft (10 m) using a hand-held Key Fob
with RKE transmitter. The RKE transmitter does
not need to be pointed at the vehicle to activate
the system.

3. Remove and replace the battery. When re-
placing 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.
4. To assemble the RKE transmitter case, snap
the two halves together.
General InformationThe RKE transmitter and receivers operate on a
carrier frequency of 433.92 MHz as required by
EEC regulations. These devices must be certi-
fied to conform to specific regulations in each
individual country. Two sets of regulations are
involved: ETS (European Telecommunication
Standard) 300–220, which most countries use,
and German BZT federal regulation 225Z125,
which is based on ETC 300–220 but has addi-
tional unique requirements. Other defined re-
quirements are noted in ANNEX VI of COMMIS-
SION DIRECTIVE 95/56/EC. Operation is
subject to the following two conditions:
•This device may not cause harmful interfer-
ence. •
This device must accept any interference
received, including interference that may
cause undesired operation.
If your RKE transmitter fails to operate from a
normal distance, check for these two condi-
tions:
1. Weak battery in RKE transmitter. The ex-
pected life of the battery is a minimum of three
years.
2. Closeness to a radio transmitter such as a
radio station tower, airport transmitter, and
some mobile or CB radios.
DOOR LOCKSThe power door locks can be manually locked
from inside the vehicle by using the door lock
knob. To lock each door, push the door lock
knob on each door trim panel downward. To
unlock the front doors, pull the inside door
handle to the first detent. To unlock the rear
doors, pull the door lock knob on the door trim
panel upward. 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 fob from the ignition and lock your
vehicle.
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle.

•If your liftgate is power closing and you
put the vehicle in gear, the liftgate will
continue to power close. However, ve-
hicle movement may result in a detection
of an obstruction.
WARNING!
•Driving with the liftgate open can allow
poisonous exhaust gases into your vehicle.
You and your passengers could be injured
by these fumes. Keep the liftgate closed
when you are operating the vehicle.
• If you are required to drive with the liftgate
open, make sure that all windows are
closed, and the climate control blower
switch is set at high speed. Do not use the
recirculation mode.
Gas props support the liftgate in the open
position. However, because the gas pressure
drops with temperature, it may be necessary to
assist the props when opening the liftgate in
cold weather.
OCCUPANT RESTRAINTSSome of the most important safety features in
your vehicle are the restraint systems:
• Three-point lap and shoulder belts for the
driver and all passengers
• Advanced Front Air Bags for driver and front
passenger
• Supplemental Active Head Restraints (AHR)
located on top of the front seats (integrated
into the head restraint)
• Supplemental Driver Side Knee Air Bag
• Supplemental Side Air Bag Inflatable Cur-
tains (SABIC) for the driver and passengers
seated next to a window
• Supplemental Seat-Mounted Side Air Bags
(SAB)
• An energy-absorbing steering column and
steering wheel
• Knee bolsters/blockers for front seat occu-
pant •
Front seat belts incorporate pretensioners
that may enhance occupant protection by
managing occupant energy during an im-
pact event
• All seat belt systems (except the driver’s and
front passenger) include Automatic Locking
Retractors (ALRs), which lock the seat belt
webbing into position by extending the belt
all the way out and then 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 Air Bags have a multi-
stage inflator design. This allows the air bag
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

3. Slide the latch plate upward over the folded
webbing. The folded webbing must enter the
slot at the top of the latch plate.
4. Continue to slide the latch plate up until it
clears the folded webbing.
Adjustable Upper Shoulder Belt
Anchorage
In the front seating positions, the shoulder belt
can be adjusted upward or downward to posi-
tion the belt away from your neck. Press the
release button to release the anchorage, and
then move it up or down to the position that
serves you best.As a guide, if you are shorter than average, you
will prefer a lower position, and if you are taller
than average, you will prefer a higher position.
When you release the button, verify the shoul-
der belt anchorage is latched by pulling down-
ward on the shoulder belt anchorage until it is
locked into position.
NOTE:
The adjustable upper shoulder belt anchor-
age is equipped with an Easy Up feature.
This feature allows the shoulder belt an-
chorage to be adjusted in the upward posi-
tion without pressing the release button. To
verify the shoulder belt anchorage is
latched, pull downward on the shoulder belt
anchorage until it is locked into position.
In the rear seat, move toward the center of the
seat to position the belt away from your neck.
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 UsingThe Vehicle Seat Belt” under the “Child Re-
straints” section. The chart below defines the
type of feature for each seating position.

If the passenger seating position is equipped
with an ALR and is being used for normal
usage:
Only pull the belt webbing out far enough to
comfortably wrap around the occupant’s mid-
section so as to not activate the ALR. If the ALR
is activated, you will hear a ratcheting sound as
the belt retracts. Allow the webbing to retract
completely in this case and then carefully pull
out only the amount of webbing necessary to
comfortably wrap around the occupant’s mid-
section. Slide the latch plate into the buckle
until you hear a click.

Enhanced Seat Belt Use Reminder
System (BeltAlert)
BeltAlertis a feature intended to remind the
driver and front passenger (if equipped with
front passenger BeltAlert) to fasten their seat
belts. The 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 seat belts are
fastened.
The BeltAlert warning sequence begins after
the vehicle speed is over 5 mph (8 km/h), by
blinking the Seat Belt Reminder Light and
sounding an intermittent chime. Once the se-
quence starts, it will continue for the entire
duration or until the respective seatbelts are
fastened. After the sequence completes, the
Seat Belt Reminder Light remains illuminated
until the respective seat belts are fastened. The
driver should instruct all other occupants to
fasten their seat belts. If a front seat belt is
unbuckled while traveling at speeds greater
than 5 mph (8 km/h), BeltAlert will provide
both audio and visual notification. 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.
BeltAlert can be enabled or disabled by your
authorized dealer. Chrysler Group LLC does
not recommend deactivating BeltAlert .
NOTE:
Although BeltAlert has been deactivated,
the Seat Belt Reminder Light will continue to
illuminate while the driver’s or front passen-
ger (if equipped with belt alert) seat belt
remains unfastened.
Seat Belt 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.
Pregnant women should wear the lap part of
the belt across the thighs and as snug across
the hips as possible. Keep the belt low so that
it does not come across the abdomen. That
way the strong bones of the hips will take the
force if there is an accident.
Supplemental Restraint System
(SRS) — Air Bags
This vehicle has Advanced Front Air Bags for
both the driver and front passenger as a
supplement to the seat belt restraint systems.
The driver’s Advanced Front Air Bag is
mounted in the center of the steering wheel.
The passenger’s Advanced Front Air Bag is
mounted in the instrument panel, above the
