Immobilizer Operation - Cadillac SRX 2012 Owner's Manual

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, located in the
instrument panel 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 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
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
located in the center console.
See "NO REMOTE DETECTED"
under Key and Lock Messages on
page 5 36.
I n f o r ma t i o n P r o v i d e d b y :
If the ignition modes will not
change with the other transmitter,
your vehicle needs service. If the
ignition does change modes, the
first transmitter may be faulty.
See your dealer who can service
the theft-deterrent system and have
a new RKE transmitter programmed
to the vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see "Programming
Transmitters to the Vehicle" under
Remote Keyless Entry (RKE)
System Operation on page 2 3.
Do not leave the key or device
that disarms or deactivates the
theft-deterrent system in the vehicle.
