Optical Alarm Function

The PSE control module (combined) (A37) or ATA control module (N26) controls the optical signals. The sequence differs depending on the national version.

- ECE: Hazard warning flashers flash for 5 minutes in intervals
- (CH): Low-beam headlights are switched on continuously
- (USA): Fog lamps and tail lamps flash for 2.5 minutes in intervals
- All: Front and rear interior lighting is switched on (when interior lamp switch is in the "on" position)


NOTE: The alarm can be terminated by activating or deactivating the ATA. After termination of the alarm the ATA remains activated.
