Engine immobiliser system

The engine immobiliser system is a
theft prevention system. When you in-
sert the key in the ignition switch, the
transponder chip in the key's head
transmits an electronic code to the ve-
hicle. The engine will start, only when
the electronic code in the chip corre-
sponds to the registered ID code for
the vehicle.
