ENGINE IMMOBILISER SYSTEM
11sa04
The engine immobiliser system is a theft prevention
system. When you insert the key in the ignition switch, the
transponder chip in the key’s head transmits an electronic
code to the vehicle. The engine will start only when the
electronic code in the chip corresponds to the registered
ID code for the vehicle.
The system is automatically set when the key is removed from
the ignition switch. At this time, the security indicator light
flashes. When you insert the key in the ignition switch, the
security indicator light goes out and the system is canceled
automatically, which enables the engine to start.
The transponder chip of the flat key is in its key case. You can
cancel the engine immobiliser system using the flat key. (For
details, see “Flat key” on page 9.)
