headlights turn off automatically?

Hello,

These year of Audi A4 did not come with automatic headlights. So they will not got off automatically when you turn off the engine.
However if the lights are left on then you will hear a chime to remind you to turn them off.

Keep in mind that the headlights can drain the battery fast if they are left on.
