CAUTION!
An unlocked car is an invitation to thieves. Always
remove the key from the ignition and lock all the
doors when leaving the vehicle unattended.
Locking Doors With A Key
You can insert the key with either side up. To lock the
door, turn the key to the right. To unlock the door, turn
the key to the left. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for further information.
Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition
and the ignition position is LOCK or ACC, sounds a
signal to remind you to remove the key.
NOTE:With the driver’s door open and the key in the
ignition, the power door locks will not lock and Remote
Keyless Entry (RKE) transmitter will not function.
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 ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys 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 someone uses an invalid key to try to start the
engine.
NOTE: A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
14 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. In addition, if the Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key 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 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 keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:
Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keys from the vehicle
and lock all doors when leaving the vehicle unat-
tended.
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 keys. Du-
plication of keys may be performed at an authorized
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15

dealer or by following the customer key programming
procedure. This procedure consists of programming a
blank key to the vehicle electronics. A blank key is one
that has never been programmed.
NOTE:When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to an
authorized dealer.
Customer Key Programming
If you have two valid Sentry Keys , you can program
new Sentry Keys to the system by performing the
following procedure:
1. Cut the additional Sentry Key Transponder blank(s)
to match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch. Turn
the ignition switch to the ON/RUN position for at least
three seconds, but no longer than 15 seconds. Then, turn
the ignition switch to the LOCK position and remove the
first key. 3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ON/RUN position within
15 seconds. After 10 seconds, a chime will sound. In
addition, the Vehicle Security Light will begin to flash.
Turn the ignition switch to the LOCK position and
remove the second key.
4. Insert a blank Sentry Key
into the ignition switch.
Turn the ignition switch to the ON/RUN position within
60 seconds. After 10 seconds, a single chime will sound.
In addition, the Vehicle Security Light will stop flashing.
To indicate that programming is complete, the Vehicle
Security Light will turn on again for three seconds and
then turn off.
The new Sentry Key is programmed.The Remote
Keyless Entry (RKE) transmitter will also be pro-
grammed during this procedure.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Repeat this procedure to program up to eight keys. If you
do not have a programmed Sentry Key, contact your
authorized dealer for details.
NOTE:If a programmed key is lost, see your authorized
dealer to have all remaining keys erased from the sys-
tem’s memory. This will prevent the lost key from
starting your vehicle. The remaining keys must then be
reprogrammed. All vehicle keys must be taken to an
authorized dealer at the time of service to be
reprogrammed.
General Information
The Sentry Key system 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 unde-
sired operation.
VEHICLE SECURITY ALARM — IF EQUIPPED
This Vehicle Security Alarm monitors the doors, liftgate,
and ignition switch for unauthorized operation.
When the alarm is activated, the interior switches for
door locks are disabled. 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 the disturbance
is still present (driver’s door, passenger door, other doors,
ignition) after three minutes, the parking lights and tail
lights will flash for an additional 15 minutes.
To Arm The System
1. Remove the key from the ignition switch and get out
of the vehicle.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

2. Lock the door using either the power door LOCK
switch or the Remote Keyless Entry (RKE) transmitter
and close all doors.
3. The Vehicle Security Light in the instrument cluster
will flash rapidly for approximately 16 seconds. This
shows that the Vehicle Security Alarm is arming. During
this period, if a door is opened, the ignition switch is
turned to ON/RUN, or the power door locks are un-
locked in any manner, the Vehicle Security Alarm will
automatically disarm. After approximately 16 seconds,
the Vehicle Security Light will flash slowly. This shows
that the Vehicle Security Alarm is fully armed.
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 Disarm The System
Press UNLOCK on the RKE transmitter, or insert the key
into the ignition switch and turn the ignition switch to
the ON/RUN position.
If something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times and
exterior lights blink 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 RKE transmitter,
once the Vehicle Security Alarm is armed (after 16 sec-
onds), 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.

EQUIPPED
This system allows you to lock or unlock the doors and
liftgate or activate the Panic Alarm from distances up to
approximately 66 ft (20 m) using a hand-held Remote
Keyless Entry (RKE) transmitter. The RKE transmitter
does not need to be pointed at the vehicle to activate the
system.NOTE:The line of transmission must not be blocked
with metal objects.
