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 vehicle is
turned off.
The immobilization system is
disarmed when the pushbutton start
is activated to enter the ACC/
ACCESSORY mode or the ON/
RUN/START mode and a valid
transmitter is present in the vehicle.
The security light in the instrument
cluster comes on if there is a
problem with arming or disarming
the theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched
RKE 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 may come 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
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, ON/
RUN/START, OFF), and the RKE
transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
in the center console. See Key and
Lock Messages 0138.
