SENTRY KEY
The Sentry KeyImmobilizer System prevents unautho-
rized 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 Key Fob with factory-mated 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 not allow the engine to crank if an invalid
Key Fob is used to start and operate the vehicle.
After placing the ignition switch in the 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. This
condition 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.
NOTE:
The Sentry Key Immobilizer System is not
compatible with 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.

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.
•For vehicles equipped with Keyless 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.

•This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.
VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors
for unauthorized entry and the ignition switch (and
Keyless Go Start/Stop button) for unauthorized opera-
tion. If something triggers the alarm, the Vehicle Security
Alarm will prevent the vehicle from starting and provide
the following audible and visible signals: the horn will
pulse, the headlights, park lamps and/or turn signals
will flash, and the Vehicle Security Light in the instru-
ment cluster will flash.
Rearming of the System
If something triggers the alarm, and no action is taken to
disarm it, the Vehicle Security Alarm will turn the horn
off after three minutes, turn all of the visual signals off
after 15 minutes, and then the Vehicle Security Alarm will
rearm itself.
To Arm the System
Vehicles Not Equipped with Keyless 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 Security Alarm is not arming. In
addition, if you open a door during the arming period,
the Vehicle Security Alarm will cancel the arming pro-
cess. 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 Go
Press the Keyless Go Start/Stop button until the Elec-
tronic Vehicle Information Center (EVIC) indicates that
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

the vehicle ignition isOFF(refer to “Starting Proce-
dures” in “Starting And Operating” for further informa-
tion). Then either press the power door LOCK switch
while the driver or passenger door is open, press the
Remote Keyless Entry (RKE) transmitter LOCK button or
press the Passive Entry Door Handle LOCK button (refer
to “Door Locks” in “Things To Know Before Starting” for
further information).
To Disarm the System
Vehicles Not Equipped with Keyless 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 position.
NOTE:
•The driver’s door key cylinder and the trunk button on
the RKE transmitter cannot arm or disarm the Vehicle
Security Alarm.
•The Vehicle Security Alarm remains armed during
trunk entry. Pressing the TRUNK button will not
disarm the Vehicle Security Alarm. If someone enters
the vehicle through the trunk, 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 protect 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 oc-
curred, 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
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

exterior lights will flash, the horn will sound, and the
ignition will not start the vehicle. If this occurs, disarm
the Vehicle Security Alarm.
Vehicles Equipped with Keyless Go
Either press the UNLOCK button on the RKE transmitter
or grasp the Passive Entry Unlock Door Handle (refer to
“Door Locks” in “Things To Know Before Starting” for
further information), press the Keyless Go Start/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 removed) and rotate it to the RUN
position.
Tamper Alert
If something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times when you
disarm the Vehicle Security Alarm. Check the vehicle for
tampering.
ILLUMINATED ENTRY — IF EQUIPPED
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter or unlock any
door.
The lights will fade to off after approximately 30 seconds
or they will immediately fade to off once the ignition
switch is turned ON from the LOCK position.
NOTE:None of the courtesy lights will operate if the
dimmer control is in the “defeat” position (extreme
downward position), unless the overhead map/reading
lights are turned on manually.
REMOTE KEYLESS ENTRY (RKE)
The RKE system allows you to lock or unlock the doors,
open the trunk, or activate the Panic Alarm from dis-
tances up to approximately 66 ft (20 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.
