Central Electronic Module (CEM) (2005-2007): Design: Horn

There are two horns in front of the radiator. There are four switches in the steering wheel. The horn is activated when one of these is closed.

The signal continues for as long as the switch is closed.

The horn is also activated when the panic alarm button on the remote control is pressed (certain markets).

The power supply for the horn is controlled from the central electronic module (CEM).
