mation center (EVIC) Section of your Owner’s Manual
for details.
WARNING!
Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake, brake pedal or the gear selector
lever. Don’t leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove key from the ignition and lock all doors
when leaving the vehicle unattended.
Key-In-Ignition Reminder
If you open the driver’s door and the key is in the ignition
switch, a chime will sound to remind you to remove the
key.
NOTE:The Key-In-Ignition reminder only occurs when
the ignition key is placed in the LOCK or ACC positions.
SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized operation of the vehicle by disabling the engine.
The system will shut the engine off after 2 seconds of
running if an invalid key is used to start the vehicle. This
system utilizes ignition keys which have an electronic
chip (transponder) embedded into them. Only keys that
have been programmed to the vehicle can be used to start
and operate the vehicle.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the Theft Alarm/
Immobilizer Light will come on for three (3) seconds
12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

immediately after the ignition switch is turned on for a
bulb check. Afterwards, if the bulb remains on, this
indicates a problem with the electronics.
If the bulb begins to flash after the bulb check, this
indicates that an invalid key has been used to start the
vehicle. Both of these conditions will result in the engine
being shut off after two (2) seconds of running.
Keep in mind that a key which has not been programmed
is also considered an invalid key even if it is cut to fit the
ignition lock cylinder for that vehicle.
If the Theft Alarm/Immobilizer Light comes on during
normal vehicle operation (vehicle has been running for
longer than 10 seconds), a fault has been detected in the
electronics and the vehicle should be serviced as soon as
possible.
NOTE:
•
The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
•Exxon/Mobil Speed Pass,™additional Sentry Keys, or
any other transponder equipped components on the
same keychain willnot
cause a key-related (tran-
sponder) 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 have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been programmed to a vehicle, it can
not be programmed to any other vehicle.
At the time of purchase, the original owner is provided
with a four digit PIN number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed at an authorized dealer or by using the
Customer Key Programming procedure. This procedure

consists of programming a blank key to the vehicle
electronics. A blank key is one which has never been
programmed.
NOTE:When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to the
dealer.
Customer Key Programming
You can program new sentry keys to the system if you
have two valid sentry keys 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 and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds a chime
will sound and the Theft Alarm Light will begin to flash.
Turn the ignition switch OFF and remove the second key.4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds a single chime will sound. The Theft Alarm Light
will stop flashing, turn on for 3 seconds; then turn off.
The new Sentry Key has been programmed.The Keyless
Entry Transmitter will also be programmed during this
procedure.
Repeat this procedure to program up to a total of 8 keys.
If you do not have a programmed sentry key, contact
your dealer for details.
NOTE:If a programmed key has been lost, see your
dealer to have all remaining keys erased from the sys-
tems memory. This will prevent the lost key from starting
your vehicle. The remaining keys must then be repro-
grammed. All vehicle keys must be taken to the dealer at
the time of service to be reprogrammed.

2. Remove and replace the battery. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean it with
rubbing alcohol.
3. To reassemble the transmitter case, snap the two
halves together. Make sure there is an even“gap”be-
tween the two halves. Test transmitter operation.
VEHICLE THEFT ALARM
This system monitors the vehicle doors and ignition
switch for unauthorized entry or operation. When the
alarm is activated, the system provides both audible and
visual signals. The horn will pulse, headlights/park
lights will flash, the Vehicle Theft Alarm/Immobilizer
light, located on the instrument panel below the Elec-
tronic Vehicle Information Center buttons will flash, and
the vehicle will not start. If the alarm is triggered and no
action is taken to disarm it, the system will turn off the
horn after three minutes and after 15 minutes of light
only operation the system will then rearm itself.
To arm the system:Remove the key from the ignition
switch and either:1. Press a power door lock switch while the driver’sor
passenger’s door is open.
2. Press the LOCK button on the keyless entry transmit-
ter.
After the last door is closed, or if all doors are closed, the
system will arm itself in about 16 seconds. During that
time, the Vehicle Theft Alarm/Immobilizer light will
flash. If it does not illuminate, the system is not arming.
If you open a door during this arming period, the system
will cancel the arming process. You must repeat one of
the previously described arming sequences to rearm the
system.
To disarm the system:Press the UNLOCK button on the
keyless entry transmitter. Also, using a valid sentry key
and moving the ignition switch to the ON/START posi-
tion will disarm the system. If you disarm the system and
access the liftgate area, the system must be rearmed, as
described previously, when closing the liftgate. If some-
thing has triggered the system in your absence, the horn
will sound three times when you disarm the system.
Check the vehicle for tampering.
