Characteristic
Distance between tone wheel and rear sensor
0.1 - 2.00 mm (0.004 - 0.079 in)

Immobilizer system operation (02_45)
For enhanced theft protection, the vehicle is equipped with an electronic immobilizer
system that is activated automatically when the ignition key is removed.
Keep the second key in a safe place since it is not possible to make a copy if it gets
lost. This would imply replacing numerous parts of the vehicle (besides the locks).
Each key in the grip has an electronic device - transponder - which modulates the
radio frequency signal emitted by a special built-in aerial in the switch when the vehicle
is started.
02_45
The modulated signal is the "password" by which the appropriate central unit recog-
nises the key and only after this occurs, it allows the engine start-up.
CAUTION
THE IMMOBILIZER SYSTEM CAN MEMORISE UP TO FOUR KEYS.
DATA STORAGE OPERATION CAN ONLY BE PERFORMED AT THE DEALER'S.
