SENTRY KEYT
The Sentry KeytImmobilizer 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 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 threeseconds 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
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
seconds), it indicates that there is a fault in the electron-
ics. Should this occur, have the vehicle serviced as soon
as possible.
NOTE:
²The Sentry KeytImmobilizer 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.

²Exxon/Mobil SpeedpassŸ, additional Sentry Keyst,
or any other transponder-equipped components on
the same key chain willnotcause a key-related
(transponder) fault unless the additional part isphysi-
cally held against the ignition keybeing used when
starting the vehicle. Cell phones, pagers, or other RF
electronics will not cause interference with this system.
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 Keytis programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keystfrom 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 keys. Du-
plication of keys may be performed at an authorized
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 KeytImmobilizer
System serviced, bring all vehicle keys with you to an
authorized dealer.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Customer Key Programming
If you have two valid Sentry Keyst, you can program
new Sentry Keystto the system by performing the
following procedure:
1. Cut the additional Sentry KeytTransponder 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 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 position within 15
seconds. After 10 seconds, a chime will sound. In addi-
tion, 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 Keytinto the ignition switch.
Turn the ignition switch to the ON 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 Secu-
rity Light will turn on again for three seconds and then
turn off.
The new Sentry Keytis programmed.The Remote
Keyless Entry (RKE) transmitter will also be pro-
grammed during this procedure.
Repeat this procedure to program up to eight keys. If you
do not have a programmed Sentry Keyt, contact your
authorized dealer for details.

disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON positions, and the
brake pedal is depressed.
SECURITY ALARM SYSTEM Ð IF EQUIPPED
This system monitors the vehicle doors and ignition for
unauthorized operation. When the alarm is activated, the
system provides both audible and visible signals. For the
first three minutes the horn will sound and the headlights
and security telltale will flash repeatedly. For an addi-
tional 15 minutes only, the headlights and security telltale
will flash. The engine will run only if a valid Sentry Keyt
is used to start the vehicle. Use of the Sentry Keytwill
disable the alarm.
Rearming of the System:
The Security Alarm System will rearm itself after the 15
additional minutes of headlights and security telltale
flashing, if the system has not been disabled. If the
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining doors and ignition.
To Set the Alarm
The alarm will set when you use the power door locks, or
use the Remote Keyless Entry (RKE) Transmitter to
LOCK the doors. After all the doors are locked and
closed, the SECURITY light in the instrument cluster will
flash rapidly to signal that the system is arming. The
SECURITY light in the instrument panel cluster will flash
rapidly for about 16 seconds to indicate that the alarm is
being set. After the alarm is set, the SECURITY light will
flash at a slower rate to indicate that the system is armed.

NOTE:If the SECURITY light stays on continuously
during vehicle operation, have the system checked by an
authorized dealer.
To Disarm the System:
Use the RKE transmitter to UNLOCK the door. If some-
thing has triggered the system in your absence, the horn
will sound three times when you unlock the doors and
the SECURITY light will flash for 30 seconds. Check the
vehicle for tampering.
The Security Alarm System will also disarm if the vehicle
is started with a programmed Sentry Keyt. If an unpro-
grammed Sentry Keytis used to start a vehicle, the
engine will run for two seconds and then the Security
Alarm will be initiated. To exit the alarming mode, press
the RKE UNLOCK button, or start the vehicle with a
programmed Sentry Keyt.
The Security Alarm System is designed to protect your
vehicle; however, you can create conditions where thesystem will arm unexpectedly. If you remain in the vehicle
and lock the doors with the RKE transmitter, the alarm will
sound when you pull the door handle to exit. The door will
be locked, but the Security Alarm System will not arm.
ILLUMINATED ENTRY SYSTEM Ð IF EQUIPPED
The courtesy lights will turn on when you use the Remote
Keyless Entry (RKE) Transmitter or open the doors. This
feature is only available if you have Remote Keyless Entry.
The lights will fade to off after about 30 seconds, or they
will immediately fade to off once the ignition switch is
turned ON.
NOTE:
²The front courtesy overhead console and door cour-
tesy lights do not turn off if the dimmer control is in
the interior lights ON position (extreme top position).
²The illuminated entry system will not operate if the
dimmer control is in the extreme downward position.

3. Continue to hold the UNLOCK button, wait at least
four seconds, but no longer than 10 seconds, then press
and hold the LOCK button. Release both buttons at the
same time.
4. To reactivate this feature, repeat the above steps.
Using The Panic Alarm
To activate the PANIC mode while the ignition is OFF,
press and release the PANIC button on the RKE trans-
mitter once. When the PANIC mode is activated, the
interior lights will illuminate, the headlamps and parking
lights will flash, and the horn will sound.
To cancel the PANIC mode press and release the PANIC
button on the transmitter a second time, after five sec-
onds. Panic mode will automatically cancel after three
minutes, or if the vehicle is started and exceeds 15 mph
(24 km/h). During the PANIC Mode, the door locks andremote keyless entry systems will function normally.
PANIC mode will not disarm the Security Alarm System
on vehicles so equipped.
