SENTRY KEY
The Sentry Key Immobilizer System prevents unauthor-
ized 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 a key fob, an Ignition Node Module,
Keyless Push Button Ignition and a RF receiver to prevent
unauthorized vehicle operation. Therefore, only key fobs
that are programmed to the vehicle can be used to start and
operate the vehicle. The system will not allow the engine to
crank if an invalid key fob is used to start and operate the
vehicle. The system will shut the engine off in two seconds
if an invalid key fob is used to start the engine.
NOTE: A key fob that has not been programmed is also
considered an invalid key.
During normal operation, after placing the keyless ignition
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 used an invalid key fob to try to start the engine. Either of these
conditions will result in the engine being 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.
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.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

VEHICLE SECURITY ALARM
The vehicle security alarm monitors the vehicle doors and
ignition for unauthorized operation. When the vehicle
security alarm 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, the
headlights will turn on, the park lamps and/or turn signals
will flash and vehicle security light will flash repeatedly.
For an additional 15 minutes only, the headlights will turn
on, the park lamps and/or turn signals, and vehicle
security light will flash.
Rearming Of The System
The vehicle security alarm will rearm itself after the 15
additional minutes of headlights and vehicle security light
flashing, if the system has not been disabled. If the condi-
tion which initiated the alarm is still present, the system
will ignore that condition and monitor the remaining doors
and ignition. To Arm The System
Follow these steps to arm the vehicle security alarm:
1. Remove the key from the ignition system (refer to
 Starting Procedures  in  Starting And Operating  for
further information).
• For vehicles equipped with Keyless Enter-N-Go — Igni-
tion, make sure the vehicle ignition system is  OFF. 
• For vehicles not equipped with Keyless Enter-N-Go —
Ignition, make sure the vehicle ignition system is  OFF 
and the key is physically removed from the ignition.
2. Perform one of the following methods to lock the vehicle:
• Push lock button on the interior power door lock
switch with the driver and/or passenger door open.
• Push the lock button on the exterior Passive Entry
Door Handle with a valid key fob available in the same
exterior zone (refer to  Keyless Enter- N-Go — Passive
Entry  in  Things To Know Before Starting Your Ve-
hicle  for further information).
• Push the lock button on the key fob.
3. If any doors are open, close them.20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The vehicle security alarm will set when you use the power
door locks, or use the key fob to lock the doors. After all the
doors are locked and closed, the vehicle 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 vehicle security light will flash at a slower
rate to indicate that the system is armed.
To Disarm The System
The vehicle security alarm can be disarmed using any of
the following methods:
1. Push the unlock button on the key fob.
2. Grasp the Passive Entry Unlock Door Handle with a
valid key fob within 5 ft (1.5 m) of the passive entry door
handle. If equipped, refer to  Keyless Enter-N-Go —
Passive Entry  in  Things To Know Before Starting Your
Vehicle  for further information.
3. Cycle the ignition out of the OFF position.
• For vehicles equipped with Keyless Enter-N-Go —
Ignition, push the Keyless Ignition START/STOP but-
ton (requires at least one valid key fob in the vehicle).
• For vehicles not equipped with Keyless Enter-N-Go,
insert a valid key into the ignition switch and turn the
key to the ON position. 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, and the horn will sound. If this occurs,
disarm the vehicle security alarm.
Security System Manual Override
The vehicle security alarm will not arm if you lock the
doors using the manual door lock plunger. 2THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 21
