General Information
The following regulatory statement applies to all radio
frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and
with Industry Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions:
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
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
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 Key Fob with a factory-mated Remote
Keyless Entry (RKE) transmitter, a Keyless Push Button
Ignition 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 with an invalid Key Fob.
After placing the ignition 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 system. In
addition, if the light begins to flash after the bulb check,
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

it indicates that someone tried to use 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 system.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.
CAUTION!
•Do not make modifications or alterations to the
immobilizer system. Modifications or alterations to
the immobilization system may result in a loss of
security protection.
• The Sentry Key Immobilizer system is not compat-
ible with some aftermarket remote starting sys-
tems. 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.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
When having the Sentry Key Immobilizer System serviced,
bring all vehicle keys with you to an authorized dealer.
Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.

VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors
for unauthorized entry and the Keyless Enter-N-Go
Start/Stop button 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 following audible and visible
signals:
• The horn will pulse.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

•The park lamps and/or turn signals will flash.
• 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 three minutes, turn all of the visual signals off
after 15 additional 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 to Starting Procedures inStarting
And Operating for 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 to Keyless Enter-N-Goin
Things To Know Before Starting Your Vehicle for
further information).
• Push the LOCK button on the Remote Keyless Entry
(RKE) transmitter.
3. If any doors are open, close them.
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 with a
valid Key Fob available in the same exterior zone (if
equipped). Refer to Keyless Enter-N-Go inThings To
Know Before Starting Your Vehicle for further infor-
mation.
• Cycle the vehicle ignition system out of the OFF
position.
• For vehicles equipped with Keyless Enter-N-Go,
push the Keyless Enter-N-Go Start/Stop button (re-
quires at least one valid Key Fob in the vehicle). •
For vehicles not equipped with Keyless Enter-N-Go,
insert a valid key into the ignition switch and turn
the key to the ON 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 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
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 21

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.
ILLUMINATED ENTRY
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. Refer to “Mirrors” in
“Understanding The Features Of Your Vehicle” for fur-
ther 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:Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
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 automatic
transmission to be equipped with Remote Start.
• Obstructions between the vehicle and RKE transmitter
may reduce this range.
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 closed
• Hazard switch off
• Brake switch inactive (brake pedal not pushed)
• Battery at an acceptable charge level
• RKE PANIC button not pushed
• System not disabled from previous remote start event
