Hazard warning flashers

The hazard warning flashers are activated by pressing the hazard warning switch. All turn indicators are activated simultaneously while the hazard warning switch display within the instrument panel (KOMBI) also flashes.

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 turn signal/high beam switch is used to activate the turn indicator light while the hazard warning flashers are operating, the turn indicator light assumes priority. The system reverts to operation of the hazard warning flashers after "Terminal 15 off" or when the turn indicator light has returned to its original position.

If the hazard warning switch is depressed while the turn indicator light is operating, then the hazard warning flashers assume priority.

Hazard warning flashers during dangerous or emergency braking 

The hazard warning flashers are automatically activated and then deactivated following emergency or dangerous braking.

Hazard warning flashers when anti-theft alarm system triggers alarm 

When an alarm is triggered, the footwell module (FRM) receives the command to activate the hazard warning flashers via K CAN2. The signal is generated by the ultrasonic interior movement detector. The hazard warning flashers continue for 6 minutes provided that the anti-theft alarm system is not switched off in the intervening period. 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 ultrasonic interior movement detector is completely integrated within the roof function center (FZD).
