22GETTING TO KNOW YOUR VEHICLE
After placing the ignition switch in the ON/RUN
position, the vehicle security light will turn on for
three 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 light begins to flash after the
bulb check, it indicates that someone
attempted to start the engine with an invalid key
fob. In the event that a valid key fob is used to
start the engine but there is an issue with the
vehicle electronics, the engine will start and
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 electronics. Should this occur,
have the vehicle serviced as soon as possible by
an authorized dealer. All of the key fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
KEY PROGRAMMING
Programming key fobs may be performed at an
authorized dealer.
REPLACEMENT KEYS
NOTE:
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle.
NOTE:
Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has
never been programmed.
When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.

NOTE:
The driver's door key cylinder and the trunk
button on the key fob cannot arm or disarm
the vehicle security alarm.
When the vehicle security alarm is armed,
the interior power door lock switches will not
unlock the doors.
The vehicle security alarm is designed to protect
your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the vehicle security
alarm will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the vehicle security alarm.
If the vehicle security alarm is armed and the
battery becomes disconnected, the vehicle
security alarm will remain armed when the
battery is reconnected; the exterior lights will
flash, the horn will sound. If this occurs, disarm
the vehicle security alarm.
REARMING OF THE SYSTEM
If something triggers the alarm, and no action is
taken to disarm it, the vehicle security alarm will
turn the horn off after 29 seconds, five seconds between cycles, up to eight cycles if the trigger
remains active and the vehicle security alarm
will rearm itself.
TAMPER ALERT
If something has triggered the vehicle security
alarm in your absence, the horn will sound three
times and the exterior lights will blink three
times when you disarm the vehicle security
alarm. Check the vehicle for tampering.
