AUTO* - The automatic headlights switch on (and off again) automatically according to the ambient light conditions (for instance at dusk, in the rain or in a tunnel). On Audi A3s with integrated daytime running lights*, the daytime running lights or the dipped headlights (different versions for different countries) are switched on automatically, depending on the ambient light level.

- Front fog lights
- Rear fog light(s)All-weather lights*
Applies to Audi A3s with LED headlights
- All-weather lights (in place of the front fog light switch .)On Audi A3s with all-weather lights, the front lights are adjusted automatically so that the headlights on your own Audi A3 do not blind you, for instance when driving on a wet road.
Headlight range control 
Your Audi A3 is equipped with a headlight range control to prevent oncoming traffic from being dazzled when the Audi A3 is heavily laden.
On Audi A3s with xenon headlights* or LED headlights*, the headlight beam settings are adjusted automatically (even during braking and acceleration).
On Audi A3s with halogen headlights, the knob Fig. 1 must be used to adjust the headlight beam settings:
- Briefly press the knob to release it.
- Turn the knob towards 3 or 0 to reduce or increase the range of the headlights.
- Briefly press the knob again to engage it.

Audi adaptive light*
The adaptive light is activated only when the light switch is set to AUTO. You can deactivate the adaptive light on the MMI* ►Link.
When the lights are on, they are automatically adapted to bends in the road, depending on the speed of the Audi A3 and the steering wheel angle. This feature provides better illumination when you drive through a corner. The system is active at speeds from approximately 10 km/h to 110 km/h.
Static cornering light (turning light)* (on Audi A3s with adaptive light) - the turning light is automatically activated when the steering wheel angle exceeds a specified value (up to about 70 km/h) or when the turn signals are switched on (up to about 40 km/h). This feature provides better illumination at the side of the Audi A3 when you turn off at a junction.
Speed-dependent light distribution* - The speed-dependent light distribution adjusts the Audi A3 lighting as required in towns, on motorways and on other main roads. Intersections can also be illuminated if your Audi A3 is equipped with a navigation system*.
Motorway light function*
(On Audi A3s with adaptive light or LED headlights) - this function adjusts the Audi A3 lighting on motorways according to your speed.
- The automatic headlights* are only intended to assist the driver. The driver must always ensure that the headlights are used when required, and may have to switch them on manually when the light conditions or visibility are poor. For example, the light sensors are not able to detect fog. Therefore, you should always switch on the dipped headlights in these conditions and when driving after dark.
- Observe all relevant statutory requirements when using the lighting systems described here.
Caution!
To avoid dazzling the traffic behind you, the rear fog light should only be used in accordance with statutory regulations.
Note
- The light sensor for the automatic headlights* is located in the mounting for the interior mirror. Do not affix any stickers on this section of the windscreen.
- Some of the settings for the exterior lighting can be adjusted ►Link.
- A buzzer will sound if you switch off the ignition and open the door when the exterior lighting is on.
- On Audi A3s for some markets, the rear lights remain off when the daytime running lights are switched on.
- In cool or damp weather, the inside of the headlights, turn signals or rear lights can sometimes mist up, due to the temperature difference between the interior and exterior of the car. They should clear again partially or completely soon after you switch on the headlights. This phenomenon has no influence on the life expectancy of the Audi A3 lights.
- If you are towing a trailer or caravan equipped with a rear fog light on a Audi A3 with a factory-fitted towing bracket, only the rear fog light on the trailer or caravan will light up.
