Key-In-Ignition Reminder
If you open the driver’s door with the integrated ignition
key in the ignition, a chime will sound to remind you to
remove the key.
NOTE:The Key-In-Ignition reminder only sounds
when the integrated ignition key is placed in the LOCK
or ACC position.
SENTRY KEY
The Sentry Key Immobilizer 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 the factory-mated Remote Keyless Entry
(RKE) transmitter with integrated key and Wireless Igni-
tion Node (WIN) to prevent unauthorized vehicle opera-
tion. Therefore, only RKE transmitters that are pro-
grammed 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 RKE transmitter is used to start the
engine.
After turning the ignition switch to the ON 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 transmitter
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 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 RKE transmitters provided with your new
vehicle have been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only RKE transmitters that are programmed to
the vehicle electronics can be used to start and operate
the vehicle. Once an RKE transmitter is programmed to a
vehicle, it cannot be programmed to any other vehicle.
CAUTION!
Always remove the keys from the vehicle and lock all
doors when leaving the vehicle unattended. 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 RKE trans-
mitters. Duplication of RKE transmitters may be per-
formed at an authorized dealer, this procedure consists of
programming a blank transmitter to the vehicle electron-
ics. A blank transmitter is one that has never been
programmed.
NOTE:
When having the Sentry Key Immobilizer
system serviced, bring all vehicle RKE transmitters with
you to the authorized dealer.
Customer Key Programming
Programming of RKE transmitters may be performed at
an authorized dealer.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

General Information
The Sentry Keysystem complies with FCC rules Part 15
and with RSS-210 of Industry Canada. Operation is
subject to the following conditions:
•This device may not cause harmful interference.
•This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.
VEHICLE SECURITY ALARM
This Vehicle Security Alarm monitors the vehicle doors,
liftgate, liftgate flipper glass, and ignition for unautho-
rized operation. When the alarm is activated, the Vehicle
Security Alarm provides both audio and visual signals.
The horn will sound, the headlights, park lamps and/or
turn signals will flash repeatedly for three minutes. If
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 addi-
tional 15 minutes.
NOTE:
The Panic and Security alarms are quite differ-
ent. 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 Set the Alarm
The alarm will set when you use the Remote Keyless
Entry (RKE) transmitter to lock the doors and liftgate, or
when you use the power door lock switch while the door
is open. After all the doors are locked and closed, the
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

Vehicle Security Light (located in the instrument cluster)
will flash rapidly for about 16 seconds to signal that the
Vehicle Security Alarm is arming. During this 16 second
arming period, opening any door or the liftgate will
cancel the arming. If the Vehicle Security Alarm success-
fully arms, the Vehicle Security Light will flash at a
slower rate to indicate the alarm is set.
To Disarm the System
To disarm the Vehicle Security Alarm, you will need to
press the UNLOCK button on the RKE transmitter or
turn the ignition key to the ON position. If something has
triggered the Vehicle Security Alarm in your absence, the
horn will sound three times when you unlock the doors.
Check the vehicle for tampering.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
Vehicle Security Alarm will arm unexpectedly. If you
remain in the vehicle and lock the doors with the RKEtransmitter, once the Vehicle Security Alarm is armed
(after 16 seconds), when you pull the door handle to exit,
the alarm will sound. If this occurs, press the UNLOCK
button on the RKE transmitter to disarm the Vehicle
Security Alarm. You may also accidentally disarm the
Vehicle Security Alarm by unlocking the driver’s door
with the key and then locking it. The door will be locked
but the Vehicle Security Alarm will not arm.ILLUMINATED ENTRY
The interior lights come on when you open any door or
use the Remote Keyless Entry (RKE) transmitter to un-
lock any door. They will remain on for approximately
30 seconds after all doors are closed then fade to off.
The lights also will fade to off if you turn on the ignition
after you close all the doors.
20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If your RKE transmitter fails to operate from a normal
distance, check for these two conditions:
1. A weak battery in the RKE transmitter. The expected
life of the battery is a minimum of three years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
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 328 ft (100 m).
NOTE: The vehicle must be equipped with an auto-
matic transmission to be equipped with Remote Start.
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 pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level
•RKE PANIC button not pressed

on the RKE transmitter twice, within five sec-
onds. The parking lights will flash and the horn
will chirp twice (if programmed). Then, the
engine will start and the vehicle will remain in the
Remote Start mode for a 15 minute cycle. NOTE:
•If an engine fault is present the vehicle will start and
then shut down 10 seconds later.
•The park lamps will turn on and remain on during
Remote Start mode.
•For security, power window and power sunroof op-
eration (if equipped) are disabled when the vehicle is
in the Remote Start mode.
•The engine can be started two consecutive times (two
15 minute cycles) with the RKE transmitter. However,
the ignition switch must be cycled to the ON position
before you can repeat the start sequence for a third
cycle.
To Exit Remote Start Mode Without Driving the
Vehicle
Press and release the REMOTE START button one time or
allow the engine to run for the entire 15 minute cycle.

•For personal security and safety in the event of an
accident, lock the vehicle doors when you drive, as
well as when you park and leave the vehicle.
•When leaving the vehicle, always remove the key
from the ignition and lock your vehicle. Do not
leave unattended children in the vehicle, or with
access to an unlocked vehicle. Unsupervised use of
vehicle equipment may cause severe personal in-
juries and death.
