In countries which allow the daytime running lights to be switched off/on, this can be done via the MMI*. In other countries, the daytime running lights stay on permanently.
Headlamp converter for driving abroad*
The asymmetric low beams of the headlights are designed to light up the nearside of the road more intensely. On Audi A3s with LED headlights* or xenon headlights* with turning light*, the headlight dip settings must be modified if you drive a right-hand drive Audi A3 in a left-hand drive country, or vice versa. Otherwise you will dazzle oncoming traffic. On Audi A3s with halogen or xenon headlights without turning light, it is not necessary to change the dip settings.
To avoid dazzling oncoming traffic:
- On Audi A3s with LED headlights* or xenon headlights* with turning light*, the headlamp converter must be activated. Select MENU button > Car > control button Systems* > Audi A3 settings > Exterior lighting > e.g. Lights for driving on left.
A message appears when the headlight settings have been changed:
Applies to left-hand drive Audi A3s:
Headlamp converter active for driving on left. Range reduced!Applies to right-hand drive Audi A3s:
Headlamp converter active for driving on right. Range reduced!Note
If the headlamp converter is activated, this is displayed in the driver information system every time the ignition is switched on.
