SENTRY KEY
The Sentry KeyImmobilizer 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 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 posi-
tion, 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 sec-
onds), 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 compat-
ible 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 programmed to any other vehicle.
CAUTION!
•Always remove the Key Fobs from the vehicle and
lock all doors when leaving the vehicle unat-
tended.
•With Keyless Enter-N-Go, always remember to
place the ignition in OFF.
At the time of purchase, the original owner is provided
with a four-digit Personal Identification 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 autho-
rized 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 Key Fobs with you to
the authorized dealer.
Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.
General Information
The Sentry Key system complies with FCC rules Part 15
and with RSS-210 of Industry Canada. Operation is
subject to the following conditions:
•This device may not cause harmful interference.
20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•This device must accept any interference that may be
received, including interference that may cause unde-
sired operation.
VEHICLE SECURITY ALARM — IF EQUIPPED
This Vehicle Security Alarm monitors the vehicle doors,
liftgate, liftgate flipper glass, and ignition for unauthor-
ized operation. When the alarm is activated, the interior
switches for door locks, power liftgate and flipper glass
are disabled. The Vehicle Security Alarm provides both
audio and visual signals, the horn will sound, the head-
lights, park lamps and/or turn signals will flash repeat-
edly for three minutes. If the disturbance is still present
(driver’s door, passenger door, other doors, ignition) after
three minutes, the headlights, park lamps and/or turn
signals will flash for an additional 15 minutes.
NOTE:The Panic and Security alarms are quite differ-
ent. Please take a moment to activate the Panic and the
Security modes to hear the differences in the horn. In case one should go off in the future, you will need to know
which mode has been activated in order to deactivate it.
Rearming The System
If something triggers the alarm, and no action is taken to
disarm it, the Vehicle Security Alarm will turn off the
horn after three minutes, turn off all of the visual signals
after 15 minutes, and then the Vehicle Security Alarm will
rearm itself.
To Arm The System
Vehicles Not Equipped With Keyless Enter-N-Go
The alarm will set when you use the Remote Keyless
Entry (RKE) transmitter to lock the doors and liftgate, or
when you use the power door lock switch while the door
is open. After all the doors are locked and closed, the
Vehicle Security Light (located in the instrument cluster)
will flash rapidly for about 16 seconds to signal that the
Vehicle Security Alarm is arming. During this 16 second
arming period, opening any door or the liftgate will
2

cancel the arming. If the Vehicle Security Alarm success-
fully arms, the Vehicle Security Light will flash at a
slower rate to indicate the alarm is set.
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 “Starting And Operating” for further
information). Then either press the power door LOCK
switch 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
“Keyless Enter-N-Go” in “Things To Know Before Start-
ing Your Vehicle” for further information).To Disarm The System
Vehicles Not Equipped With Keyless Enter-N-Go
To disarm the Vehicle Security Alarm, you will need to
press the UNLOCK button on the RKE transmitter or
turn the ignition switch to the ON/RUN position. If
something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times when you
unlock the doors. Check the vehicle for tampering.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
Vehicle Security Alarm will arm unexpectedly. If you
remain in the vehicle and lock the doors with the RKE
transmitter, once the Vehicle Security Alarm is armed
(after 16 seconds), when you pull the door handle to exit,
the alarm will sound. If this occurs, press the UNLOCK
button on the RKE transmitter to disarm the Vehicle
Security Alarm. You may also accidentally sound the
Vehicle Security Alarm by unlocking the driver ’s door
with the key and then opening the door.
22 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If your RKE transmitter fails to operate from a normal
distance, check for these two conditions:
1. A weak battery in the RKE transmitter. The expected
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.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE: The vehicle must be equipped with an auto-
matic transmission to be equipped with Remote Start.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•Liftgate/Flipper Glass closed
•Hazard switch off
•Brake switch inactive (brake pedal not pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level

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 passengers as safe as
possible.
If you will be carrying children too small for adult-sized
seat belts, the seat belts or the Lower Anchors and Tether
for CHildren (LATCH) feature also can be used to hold
infant and child restraint systems. For more information
on LATCH, see Lower Anchors and Tether for CHildren
(LATCH).
NOTE: The Advanced Front Airbags have a multistage
inflator design. This allows the airbag to have different
rates of inflation based on the severity and type of
collision.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag:
1.Children 12 years old and under should always ride
buckled up in a rear seat.
WARNING!
Infants in rear facing child restraints should never
ride in the front seat of a vehicle with a passenger
Advanced Front Airbag. An airbag deployment can
cause severe injury or death to infants in that posi-
tion.
Children that are not big enough to wear the vehicle seat
belt properly (see section on Child Restraints) should be
secured in the rear seat in child restraints or belt-
positioning booster seats. Older children who do not use
child restraints or belt-positioning booster seats should ride properly buckled up in the rear seat. Never allow
children to slide the shoulder belt behind them or under
their arm.
If a child from 1 to 12 years old (not in a rear facing child
seat) must ride in the front passenger seat, move the seat
as far back as possible and use the proper child restraint.
(Refer to “Child Restraints”)
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2.
All occupants should always wear their lap and
shoulder belts properly.
3. The driver and front passenger seats should be
moved back as far as practical to allow the Advanced
Front Airbags room to inflate.
