Cadillac 2009 XLR Automobile User Manual


 
Immobilizer Operation
The vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition is
turned off.
The immobilization system is disarmed when the ignition
is turned to OFF/ACCESSORY or START and a valid
transmitter is found in the vehicle.
You do not have to manually arm or disarm the system.
The security light comes on if there is a problem with
arming or disarming the theft-deterrent system.
The system has one or more keyless access transmitters
that are matched to an immobilizer control unit in the
vehicle. Only a correctly matched keyless access
transmitter starts the vehicle. The vehicle may not
start if the keyless access transmitter is damaged.
If the engine does not start and the security light comes
on, there may be a problem with the immobilizer system.
Press the START button again.
If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, place the transmitter in
the transmitter pocket. See “NO FOBS DETECTED”
under DIC Warnings and Messages on page 3-60 for
additional information. Check the fuse. See Fuses and
Circuit Breakers on page 6-83. If the engine still does not
start with the other transmitter, the vehicle needs service.
If the engine does start, the first transmitter may be faulty.
See your dealer/retailer or have a new keyless access
transmitter programmed to the vehicle.
The immobilizer system can learn new or replacement
keyless access transmitters. Up to four keyless access
transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” under Keyless Access
System Operation on page 2-5.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
