range adjusts automatically.
Audi adaptive light
Applies to: vehicles with Audi 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.
ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— Automatic headlights are only intended to
assist the driver. The driver is still responsi-
ble for controlling the headlights and may
need to switch them on and off manually
depending on 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.

G) 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.
— When using lighting equipment, the driver
is responsible for adhering to any local ap-
plicable regulations while driving and when
parking the vehicle.
— Only the front headlights turn on when the
daytime running lights are switched on*. In
vehicles in certain markets, the tail lights
will also turn on.
—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.

coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— For safety reasons, the hood must always be
latched securely while driving. Because of
