CAUTION!
An unlocked car is an invitation to thieves. Always
remove the Key Fob from vehicle, cycle the ignition
OFF with Keyless Enter-N-Go, and lock all doors
when leaving the vehicle unattended.
Key-In-Ignition Reminder
Opening the driver’s door when the Key Fob is in the
ignition and the ignition switch position is OFF or ACC,
sounds a signal to remind you to remove the Key Fob.
NOTE:The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or ACC ignition
position.
If your vehicle is equipped with Keyless Enter-N-Go,
opening the driver’s door when the vehicle’s ignition
switch is placed in ACC or ON/RUN (engine stopped) will cause the reminder chime to sound. Refer to “Start-
ing Procedures” in “Starting And Operating” for further
information.
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 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 shut the engine off in two seconds if an
invalid Key Fob is used to start the engine.
After placing the ignition switch in the ON/RUN posi-
tion, the Vehicle Security Light will turn on for three
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
CAUTION!
The Sentry KeyImmobilizer 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.
•For vehicles equipped 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

and with RSS-210 of Industry Canada. Operation is
subject to the following conditions:
•This device may not cause harmful interference.

VEHICLE SECURITY ALARM
The Vehicle Security Alarm monitors the vehicle doors
and trunk for unauthorized entry and the ignition switch
for unauthorized operation. While the Vehicle Security
Alarm is armed, interior switches for door locks and
decklid 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 headlights will turn on, 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 three minutes, turn all of the visual signals off
after an additional 15 minutes, and then the Vehicle
Security Alarm will rearm itself.
To Arm The System

1. Remove the key from the ignition system (refer to
Starting ProceduresinStarting And Operating for
further information).
• For vehicles equipped with Keyless Enter-N-Go, make
sure the vehicle ignition system is OFF.

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
system will give you a false alarm. If one of the
previously 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.

becomes disconnected, the Vehicle Security Alarm will
remain armed when the battery is reconnected; the
exterior lights will flash, the horn will sound. If this
occurs, disarm the Vehicle Security Alarm.

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
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter to unlock the

tesy lights will turn on if the dimmer control is in the
Dome ON
position (extreme top position).

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 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.
