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 RKE Key Fob, an Ignition Node
Module, Keyless Push Button Ignition and a RF receiver
to prevent unauthorized vehicle operation. Therefore,
only RKE 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 RKE Key
Fob is used to start and operate the vehicle. The system
will shut the engine off in two seconds if an invalid RKE
Key Fob is used to start the engine.
NOTE:A RKE Key Fob that has not been programmed is
also considered an invalid key. During normal operation, after placing the keyless igni-
tion 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 an invalid RKE 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 electron-
ics. Should this occur, have the vehicle serviced as soon
as possible by an authorized dealer.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!
The Sentry Key Immobilizer system is not compat-
ible with some aftermarket remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the RKE Key Fobs provided with your new vehicle
have been programmed to the vehicle electronics.
Replacement RKE Key Fobs
NOTE: Only RKE Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a RKE 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 Enter-N-Go,
always remember to place the ignition in the OFF
position.
NOTE: Duplication of RKE Key Fobs may be performed
at an authorized dealer. This procedure consists of pro-
gramming a blank RKE Key Fob to the vehicle electron-
ics. A blank RKE Key Fob is one that has never been
programmed.
When having the Sentry Key Immobilizer System ser-
viced, bring all vehicle keys with you to an authorized
dealer.2

1. This device may not cause harmful interference, and
2. This device must accept any interference received,including interference that may cause undesired op-
eration.
NOTE: Changes or modifications not expressly approved

VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors
for unauthorized entry and the Keyless Enter-N-Go —
Ignition for unauthorized operation. While the Vehicle
Security Alarm is armed, interior switches for door locks
and liftgate release are disabled. If something triggers the
alarm, the Vehicle Security Alarm will provide the fol-
lowing audible and visible signals: the horn will pulse,
the park lamps and/or turn signals will flash, and the
Vehicle Security Light in the instrument 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 29 seconds, 5 seconds between cycles, up to 8
cycles if the trigger remains active and then the Vehicle
Security Alarm will rearm itself.
20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Arm The System
Follow these steps to arm the Vehicle Security Alarm:
1. Make sure the vehicles ignition is cycled to the “OFF”position (refer to Starting Procedures inStarting
And Operating for further information).
• For vehicles equipped with Keyless Enter-N-Go —
Passive Entry, make sure the vehicles keyless igni-
tion system is OFF.
• For vehicles not equipped with Keyless Enter-N-Go
— Passive Entry, 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 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 RKE Key Fob available in
the same exterior zone (refer to Keyless Enter-N-Go
— Passive Entry inThings To Know Before Starting
Your Vehicle for further information).
• Push the LOCK button on the RKE Key Fob.
3. If any doors are open, close them.
To Disarm The System
The Vehicle Security Alarm can be disarmed using any of
the following methods:
• Push the UNLOCK button on the RKE Key Fob.
• Grasp the Passive Entry Unlock Door Handle (if
equipped, refer to Keyless Enter-N-Go — Passive
Entry inThings To Know Before Starting Your Ve-
hicle for further information).

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 21

•Cycle the vehicle ignition system out of the OFF
position.
• For vehicles equipped with Keyless Enter-N-Go —
Passive Entry, push the keyless ignition button (re-
quires at least one valid RKE Key Fob in the vehicle).
• For vehicles not equipped with Keyless Enter-N-Go
— Passive Entry, insert a valid key into the ignition
and turn the key to the ON position.
NOTE:
• The driver’s door key cylinder and the liftgate button
on the RKE Key Fob cannot arm or disarm the Vehicle
Security Alarm.
• The Vehicle Security Alarm remains armed during
power liftgate entry. Pushing 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 protect your
vehicle. However, you can create conditions where the
system will give you a false alarm. If one of the previ-
ously 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.
Security System Manual Override
The Vehicle Security Alarm will not arm if you lock the
doors using the manual door lock plunger.
22 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Tamper Alert
If something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times and the
exterior lights will blink 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 RKE
Key Fob to unlock the doors or after opening any door.
This feature also turns on the approach lighting in the
outside mirrors (if equipped).
The courtesy lights will fade to off after approximately 30
seconds, or they will immediately fade to off once the
ignition is placed in the ON/RUN position from the OFF
position.NOTE:
•
The front courtesy overhead console and door cour-
tesy lights will turn on if the dimmer control is in the
“Dome ON” position (extreme top position).
• The Illuminated Entry system will not operate if the
dimmer control is in the “Dome defeat” position
(extreme bottom position).
REMOTE KEYLESS ENTRY (RKE)
The RKE system allows you to lock or unlock the doors,
open the power liftgate, remote start your vehicle (if
equipped), or activate the Panic Alarm from distances up
to approximately 66 ft (20 m) using a hand-held RKE Key
Fob. The RKE Key Fob does not need to be pointed at the
vehicle to activate the system.
