Hazard warning switch

The button signals of the hazard warning switch are read into the Body Domain Controller (BDC). The hazard warning flashers are activated by pressing the hazard warning switch. During this the Body Domain Controller (BDC) activates all the turn indicators at the same time and the display of the hazard warning switch also flashes.

If the turn signal/high beam switch is pressed in the direction for left or right turns while the hazard warning flashers are operating, the turn indicator light assumes priority. The hazard warning flashers are reactivated after "Terminal 15 off" or when the turn indicator has stopped. If the hazard warning switch is depressed while the turn indicator lights are operating, then the hazard warning flashers assume priority.

With "Terminal 30 on" the hazard warning flashers are implemented in their energy-saving mode. In this mode, the hazard warning flashers light up for a shorter period and remain off for a longer period than usual. When the anti-theft alarm system is signalling an active alarm the hazard warning switch is suppressed and does not flash with the alarm system.

The hazard warning flashers are switched on automatically during an emergency braking situation.
