SENTRY KEY
The Sentry Key Immobilizer System prevents
unauthorized 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 which have an
embedded electronic chip (transponder) to
prevent unauthorized vehicle operation.
Therefore, only keys that are programmed to
the vehicle can be used to start and operate the
vehicle.
If the vehicle security light is on after the key is
turned to the MAR (ACC/ON/RUN) position, it
indicates that there is a problem with the
electronics.All of the keys provided with your new vehicle
have been programmed to the vehicle
electronics.
NOTE:
A key which 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
Ú
page 274.
IGNITION SWITCH

1. Place the gear selector in PARK.

2. Rotate the key to the STOP (OFF/LOCK)
position.
3. Remove the key from the mechanical ignition switch.
Mechanical Ignition Switch Positions

CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
1 — AVV (START)
2 — MAR (ACC/ON/RUN)
3 — STOP (OFF/LOCK)
WARNING!
Before exiting a vehicle, always shift the
automatic transmission into PARK, apply
the parking brake, turn the vehicle OFF,
remove the key fobs from vehicle, and lock
your vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.

GETTING TO KNOW YOUR VEHICLE13
NOTE:
Opening the driver's door when the key is in the
ignition and the ignition switch position is STOP
(OFF/LOCK) sounds a signal to remove the key.
VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the
vehicle doors and ignition for unauthorized
operation. When the Vehicle Security system is
activated, interior switches for door locks are
disabled. The system provides both audible and
visible signals. For the first three minutes, the
horn will sound, and the turn signal lights will
flash. For an additional 15 minutes, only the
turn signal lights will flash.
TO ARM THE SYSTEM
To arm the system, the Vehicle Security system
will set when you use the key fob to lock the
doors. If a door or the hood is not properly shut,
the system will not be armed.
TO DISARM THE SYSTEM
Use the key fob to unlock the door and disarm
the system.
The Vehicle Security system will also disarm if a
programmed Sentry Key is inserted into the
ignition switch. To exit the alarming mode,
push the key fob unlock button, or insert a
programmed Sentry Key into the ignition switch. The Vehicle Security system 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
system 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 system.
REARMING OF THE SYSTEM
If the system has not been disabled, the Vehicle
Security system will rearm itself after the 15
additional minutes of turn lamps flashing. If the
condition which initiated the alarm is still
present, the system will ignore that condition
and monitor the remaining doors and ignition.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm/disarm
if you lock/unlock the doors using the manual
door lock.
Allowing children to be in a vehicle unat
-
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren. A child could operate power windows,
other controls, or move the vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!

An unlocked vehicle is an invitation. Always
remove the key from the ignition and lock all
the doors when leaving the vehicle unattended.
