Press the corresponding switch Fig. 1:

Your Audi A5 is equipped with a headlight range control to prevent oncoming traffic from being dazzled when the Audi A5 is heavily laden.
On Audi A5s with xenon headlights*, the headlight beam settings are adjusted automatically (even during braking and acceleration).
On Audi A5s with halogen headlights, the thumbwheel Fig. 2 must be used to adjust the headlight beam settings:
O - Two front occupants, luggage compartment empty
I - All seats occupied, luggage compartment empty
II - All seats occupied, luggage compartment loaded
III - Driver only, luggage compartment loaded
Adaptive light*
The adaptive light automatically follows the contours in the road, taking the road speed and steering wheel angle into account. 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 A5s with adaptive light) - the turning light is automatically activated when the steering wheel angle exceeds a specified value 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 A5 when you turn off at a junction.
The adaptive light and turning light only work when the light switch is set to AUTO (automatic headlights*).
- 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 A5s 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 A5 lights.
