To Release the Steering Wheel Lock
Insert the key in the ignition switch and start the engine.
If the key is difficult to turn, move the wheel slightly to
the right or left to disengage the lock.
NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to
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 Transaxle Ignition Interlock System —
If Equipped
This system prevents the key from being removed unless
the shift lever is in PARK and the shift knob pushbutton
is out. It also prevents shifting out of PARK unless the
key is in the ON position and the brake pedal is
depressed.
SENTRY KEY — IF EQUIPPED
The Sentry Key Immobilizer System prevents unautho-
rized operation of the vehicle by disabling the engine. The system will shut the engine off after two 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 if the vehicle is locked or unlocked. During
normal operation, the Vehicle Security Light will come on
for three seconds 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 seconds of running.

Keep in mind that an unprogrammed key is also consid-
ered an invalid key even if it is cut to fit the ignition lock
cylinder for that vehicle.
If the Vehicle Security Light comes on during normal
vehicle operation (when the 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 by an authorized dealer.
NOTE:
•The Sentry KeyImmobilizer System is not compat-
ible with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
•Exxon/Mobil SpeedPass™, additional Sentry Keys ,
or any other transponder equipped components on the
same keychain will notcause a key-related (transpon-
der) fault unless the additional part is physically heldagainst the ignition key
being used when starting the
vehicle. Cell phones, pagers, or other radio frequency
controlled electronics will not cause interference with
this system.
All of the keys provided with a new vehicle have been
programmed to that vehicle’s 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.
CAUTION!
Always remove Sentry Keys from the vehicle and
lock all doors when leaving the vehicle unattended.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).
This PIN is required for replacement of keys by an
authorized dealer. Duplication of keys must be per-
formed at an authorized dealer. 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 KeyImmobilizer
System serviced, bring all vehicle keys with you to the
authorized dealer.
Sentry 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 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
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 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 indicator
light will turn on again for three seconds and then turn
off.

The new Sentry Keyhas been programmed. The Re-
mote Keyless Entry (RKE) transmitter will also be
programmed during this procedure. Repeat this proce-
dure to program up to a total of eight keys. If you do not
have a programmed Sentry Key, contact your autho-
rized dealer for details.
NOTE: If a programmed key is lost, see your authorized
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 autho-
rized 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 undes-
ired operation.
VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the doors, liftgate,
and ignition switch for unauthorized operation.
If something triggers the alarm, the Vehicle Security
Alarm will signal for about 18 minutes. For the first three
minutes the horn will sound and the headlights, park
lights, tail lights and the Vehicle Security Light in the
cluster will flash. Then the exterior lights will flash for
another 15 minutes.
If the monitored Vehicle Security Alarm that triggered the
alarm is deactivated, the alarm will continue to sound
until three minutes of alarm time is reached. If the
monitored Vehicle Security Alarm that triggered the
alarm is deactivated, after the alarm has been on for three
minutes the alarm will shut off immediately.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Set the Alarm
1. Remove the key from the ignition switch and get out
of the vehicle.
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 16 seconds. This shows that the
Vehicle Security Alarm is arming. During this period, if a
door is opened, the ignition switch is turned ON, or the
power door locks are unlocked by either the power door
lock switch or the RKE transmitter, the Vehicle Security
Alarm will automatically disarm. After 16 seconds, the
Vehicle Security Light will flash slowly. This shows that
the Vehicle Security Alarm is fully armed.
To Disarm the Alarm
Unlock a front door using the RKE transmitter.
Starting the vehicle with a valid Sentry Keywill disarm
the Vehicle Security Alarm. A valid key is one that is
programmed to that particular vehicle. A valid key will
disarm the Vehicle Security Alarm. An invalid key will
trigger the alarm.
Tamper Alert
If the horn sounds three times when you unlock a front
door using the RKE transmitter, the alarm has been
activated. Check the vehicle for tampering.

doors using the manual door lock plunger.
REMOTE KEYLESS ENTRY (RKE)
This system allows you to lock or unlock the doors and
liftgate, or activate the Panic Alarm from distances ap-
proximately 66 ft (20 m) using a hand-held RKE trans-
mitter. The RKE transmitter does not need to be pointed
at the vehicle to activate the system.
