Key Fob
Key Fob — If Equipped
The Key Fob operates the ignition switch. Insert the
square end of the key fob into the ignition switch located
on the instrument panel and rotate to the desired posi-
tion. It also contains the Remote Keyless Entry (RKE)
transmitter and an emergency key, which stores in the
rear of the Key Fob.
The emergency key allows for entry into the vehicle
should the battery in the vehicle or the RKE transmitter
go dead. You can keep the emergency key with you when
valet parking.
To remove the emergency key, slide the mechanical latch
at the top of the Key Fob sideways with your thumb and
then pull the key out with your other hand.NOTE:
When using the emergency key to gain access to
your vehicle, be aware that the security alarm may be
triggered. Insert the Key Fob into the ignition and place
the ignition in the ON/RUN mode to disarm the security

Keyless Push Button Ignition Key Fob — If Equipped
This Keyless Push Button Ignition Key Fob allows the
driver to operate the ignition switch with the push of a
button, as long as the Remote Keyless Entry (RKE)
transmitter is in the passenger compartment. The Keyless
Push Button Ignition has four operating positions, three
of which are labeled and will illuminate when in posi-
tion. The three positions are OFF, ACC, and ON/RUN.
The fourth position is START, during start RUN will
illuminate. It also contains the Remote Keyless Entry
(RKE) transmitter and an emergency key, which stores in
the rear of the Key Fob.
The emergency key allows for entry into the vehicle
should the battery in the vehicle or the RKE transmitter
go dead. You can keep the emergency key with you when
valet parking.To remove the emergency key, slide the mechanical latch
on the backside of the Key Fob sideways with your
thumb and then pull the key out with your other hand.

NOTE:A Key Fob that has not been programmed is also
considered an invalid key.
During normal operation, after turning on the ignition
switch, 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 electron-
ics. Should this occur, have the vehicle serviced as soon
as possible by an authorized dealer.CAUTION!
The Sentry Key Immobilizer system is not compat-
ible 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.
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.
20 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 Ve-
hicle Security Alarm is activated, interior switches for
door locks are disabled. The system provides both au-
dible and visible signals for the first three minutes the
horn will sound and 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
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining 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 toStarting Procedures inStarting And Operating for
further information).
• For vehicles equipped with Keyless Enter-N-Go,
make sure the vehicle ignition system is OFF.
• For vehicles not equipped with Keyless Enter-N-Go,
make sure the vehicle ignition system is OFFand
the key is physically removed from the ignition.
2. Perform one of the following methods to lock the vehicle:
• Push LOCK 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
22 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

same exterior zone (refer toKeyless Enter- N-Goin
Things To Know Before Starting Your Vehicle for
further information).
• Push the LOCK button on the Remote Keyless Entry
(RKE) transmitter.
3. If any doors are open, close them.
The Vehicle Security Alarm will set when you use the
power door locks, or use the Remote Keyless Entry (RKE)
transmitter 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 Remote Keyless
Entry (RKE) transmitter.
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 inThings To Know Before Starting Your Vehicle
for further information).
3. Cycle the vehicle ignition system out of the OFF position.
• For vehicles equipped with Keyless Enter-N-Go,
push the Keyless Enter-N-Go Start/Stop button (re-
quires 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
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 23

system will give you a false alarm. If one of the previ-
ously 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.
ILLUMINATED APPROACH
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter to unlock the
doors or open any door.
This feature also turns on the approach lighting in the
outside mirrors (if equipped). Refer to “Mirrors” in
“Understanding The Features Of Your Vehicle” for fur-
ther information.
The lights will fade to off after approximately 30 seconds,
or they will immediately fade to off once the ignition
switch is turned to ON/RUN from the OFF position.
The front courtesy overhead console and door courtesy
lights will not turn off if the dimmer control is in the
“Dome ON” position (rotate horizontal thumb wheel on
the bottom of the switch to the far right detent position).
