WARNING!(Continued)
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove the Key Fob from vehicle, place the ignition
in the OFF and lock all doors when leaving the
vehicle unattended.
SENTRY KEY®
The Sentry Key® Immobilizer System prevents unau-
thorized 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 Key Fob with a factory-mated Remote
Keyless Entry (RKE) transmitter, an Ignition Node Mod-
ule, Keyless Ignition Node (KIN) and a RF receiver 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. The system will shut the engine
off in two seconds if an invalid Key Fob is used to start
the engine.
NOTE:A Key Fob that has not been programmed is also
considered an invalid key.
During normal operation, after turning on the ignition
switch, 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
2

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.
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 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 Enter-N-Go™,
always remember to place the ignition in the OFF
position.
NOTE:Duplication of Key Fobs may be performed at an
authorized dealer. This procedure consists of program-
ming a blank Key Fob to the vehicle electronics. A blank
Key Fob is one that has never been programmed.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

When having the Sentry Key® Immobilizer System ser-
viced, bring all vehicle keys with you to an authorized
dealer.
Customer Key Programming
Programming Key Fobs or RKE transmitters may be

VEHICLE SECURITY ALARM — IF EQUIPPED
This Vehicle Security Alarm monitors the vehicle doors,
liftgate, and ignition for unauthorized operation. When
the alarm is activated, the interior switches for door
locks, and power liftgate are disabled. The Vehicle Secu-
rity Alarm provides both audio and visual signals; the
horn will sound, the headlights will turn on, park lamps
and/or turn signals will flash repeatedly for three min-
utes. 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

NOTE:The Panic and Security alarms are quite different.
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
Follow these steps to arm the Vehicle Security Alarm:
1. Make sure the vehicles ignition is cycled to the “OFF”
position (refer toStarting ProceduresinStarting
And Operatingfor further information).•For vehicles equipped with Keyless Enter-N-Go™,
make sure the vehicle ignition system is OFF.
•For vehicles not equipped with Keyless Enter-N-
Go™, 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 Key Fob available in the
same exterior zone (refer toKeyless Enter-N-Go™
inThings To Know Before Starting Your Vehiclefor

20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Disarm The System
The Vehicle Security Alarm can be disarmed using any of
the following methods:
•Push the UNLOCK button on the Remote Keyless
Entry (RKE) transmitter.
•Grasp the Passive Entry Unlock Door Handle (refer to
Keyless Enter-N-Go™inThings To Know Before
Starting Your Vehiclefor further information).
•Cycle the vehicle ignition system out of the OFF
position.
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. Pushing the LIFTGATE buttonwill 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.

Tamper Alert
If 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 ENTRY — IF EQUIPPED
The 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).
The 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 Key Fob
with RKE transmitter. The RKE transmitter does not need
to be pointed at the vehicle to activate the system.
