A WORD ABOUT YOUR KEYS
The double sided keys may be inserted into the locks
with either side up. The keys for your new vehicle are
enclosed in a plastic bag with a bar code label affixed to
the front. The bar code can be used to order duplicate
keys from your dealer or a locksmith. If you received
your keys without the bag, ask your dealer to give you
the number.
Key-In-Ignition Reminder
If you open the driver’s door when the key is in the
ignition switch, a chime will sound to remind you to
remove the key.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition and lock
all the doors when leaving the vehicle unattended.
SENTRY KEY — IF EQUIPPED
With this system, an electronically coded ignition key
sends a signal to the vehicle electronics. If the electronics
recognizes the signal, the vehicle will start and continue
to run. If the system does not recognize the signal the
vehicle will start and run for a maximum of 2 seconds
after the initial key ON. After six unsuccessful attempts
at starting, the system will shut down until the correct
key is used.
NOTE:The Sentry Key Immobilizer System is not
compatible with remote starting systems. Use of these
systems may result in vehicle starting problems and a
loss of security protection. Additional Sentry Keys or
Mobil Speed-pass™ devices held against or immediately
adjacent to the ignition key when starting the engine may
cause vehicle starting problems. If a problem occurs,
remove the Sentry Key from the key-ring and attempt to
start the vehicle again. Pagers, cell phones, walkman, etc.
will have no effect on this system.

TheSecurity Light, located in the instrument cluster,
will illuminate for about 2 seconds when the ignition
switch is first turned to the ON position. If the vehicle
electronics do not receive a valid signal from the ignition
key, theSecurity Lightwill flash continuously to signal
that the vehicle has been immobilized. If theSecurity
Lightremains on during vehicle operation, it indicates a
fault in the system electronics. If this option was ordered,
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 cannot
be programmed to any other vehicle.At the time of purchase, the original owner is provided
with a four digit PIN. This number is required for dealer
replacement of keys. Duplication of keys may be per-
formed 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 and
needs to be cut.
NOTE:When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.
12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Customer Key Programming
You can program new keys to the system if you have two
valid keys by doing the following:
1. Insert the first valid key into the ignition and turn the
ignition to the ON position for at least 3 seconds but no
longer than 15 seconds. Turn the ignition back to the OFF
position and remove the first key.
2. Insert the second valid key and switch the ignition to
the ON position within 15 seconds. After 10 seconds the
Security Lightwill begin to flash. Turn the ignition back
to the OFF position and remove the second key.
3. Insert a blank Sentry Key into the ignition and switch
the ignition to the ON position within 60 seconds of
having removed the second key. After 10 seconds the
Security Lightwill stop flashing, then turn on for 3
seconds; then turn off.The new Sentry Key has been programmed. Repeat this
process to program up to an additional 6 keys. A maxi-
mum of 8 keys can be programmed to the system,
including the original keys provided with the vehicle.

As a safety feature the doors will not lock when using the
door lock switches during the following condition:
1. The driver’s door is open while the key is in the
ignition.
Central Locking — If Equipped
Vehicles with security will have a feature calledCentral
Locking. When the key is placed in the door cylinder
and turned to theUnlockposition, the security will be
disarmed, the illuminated entry will be turned on and
that door will be mechanically unlocked. If the key is
once again turned to the unlock position within 5 seconds
of the first unlock, the remaining doors will unlock. If the
key is turned to theLockposition while all doors are
closed, illuminated entry will be canceled, security will
begin arming, and all doors will lock.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

door locks and remote keyless entry systems will func-
tion normally. Panic mode will not disarm the security
system on vehicles so equipped.
Programming Additional Transmitters
Vehicles with the keyless entry option will be shipped
from the assembly plants with two key fob transmitters
programmed only for that vehicle. A total of four fobs can
be programmed for your vehicle. Additional fobs can be
programmed to your vehicle through the use of a cur-
rently programmed fob.
NOTE:When entering program mode using that fob,
ALL currently programmed fobs will be erased and you
will have to reprogram them for your vehicle. However,
if program mode is entered and no action is performed,
the previously programmed fobs will continue to func-
tion.
1. Enter your vehicle and close all doors.2. Fasten your seat belt (fastening the seat belt will cancel
any chiming that may confuse you during this program-
ming procedure).
3. Place the key into the ignition.
4. Turn the ignition to the ON position (Do not start the
engine).
5. Press and hold the UNLOCK button on a programmed
(i.e. functional) key fob.
6. Continue to hold the UNLOCK button, wait at least 4
seconds, but no longer than 10 seconds, then press and
hold the PANIC button.
7. When a single chime is heard, release both buttons.
The chime indicates that the system is in program mode.
8. Press and release both the LOCK and UNLOCK
buttons, simultaneously on the fob to be programmed.
26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors and ignition for
unauthorized operation. When the alarm is activated, the
system provides both audible and visual signals. For the
first 3 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 Key
is used to start the vehicle. Use of the Sentry Key will
disable the alarm.
Rearming of the System:
The security system will rearm itself after the 15 addi-
tional 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 remaining doors
and ignition.
To Set the Alarm:
The alarm will set when you use the power door locks,
turn the key in the driver’s door lock cylinder, or use the
Keyless Entry 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
your dealer.
