and immediately arm the alarm
system.
The vehicle alarm system will not

doors are closed.
. Always unlock the vehicle with
the RKE transmitter.
Unlocking the driver door with the
key will not disarm the system or

How to Detect a Tamper
Condition
IfKis pressed and the horn chirps
and the lights flash three times, an
attempted break-in has occurred
while the system was armed.
Immobilizer
See Radio Frequency Statement
0 302.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system. The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the transmitter
leaves the vehicle.
The immobilization system is
disarmed when ENGINE START/
STOP is pressed and a valid
transmitter is found in the vehicle.
The security light in the instrument
cluster comes on when there is a
problem with arming or disarming
the theft-deterrent system.
The system has one or more
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
vehicle off and try again.
If the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the front cupholder.
See
“Starting the Vehicle with a Low
Transmitter Battery” underRemote
Keyless Entry (RKE) System
Operation 027.
If the engine does not start with the
other transmitter or when the
transmitter is in the pocket in the
front cupholder, the vehicle needs
service. See your dealer who can
service the theft-deterrent system
and have a new transmitter
programmed to the vehicle.
Do not leave the transmitter or
device that disarms or deactivates
the theft-deterrent system in the
vehicle.
