Automatic headlight range control 
Your vehicle is equipped with automatic head- 
light range control. It reduces glare for oncoming 
traffic if the vehicle load changes. The headlight 
range adjusts automatically. 
Audi adaptive light 
Applies to: vehicles with adaptive light 
Audi adaptive light provides better visibility when 
driving in the dark. The lights are adapted to the

road conditions based on speed, such as when 
driving on expressways, rural roads, at intersec- 
tions, and around curves. The adaptive lights only 
function when the light switch is in the AUTO po- 
sition and the all-weather lights are switched off. 
  
ZX WARNING 
— Follow the safety precautions and note the 
limits of the assist systems, sensors, and 
cameras > page 114. 
— Automatic headlights are only intended to 
assist the driver. They do not relieve  the 
driver of responsibility to check the head- 
lights and to turn them on manually based 
on the current light and visibility conditions. 
For example, fog cannot be detected by the 
light sensors. So always switch on the low 
beams ZO under these weather conditions 
    
and when driving in the dark. 
  
@) Tips 
— If the vehicle battery has been discharging 
for a while, the parking light may switch off 
automatically. Avoid using the parking 
lights for several hours.

—Incool or damp weather, the inside of the 
headlights, turn  signals, and tail lights can 
fog 
over due to the temperature difference 
between the inside and outside. They will 
clear shortly after switching them on. This 
does not affect the service life of the light- 
ing.
