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 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 light only
functions when the automatic headlights are ac-
tivated.

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
— 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.

— Once you drive forward at speeds faster than 9
mph (15 km/h)
— When the knob is no longer in the position for
the front passenger exterior mirror

ZX WARNING
Curved mirror surfaces (for example convex)
enlarge the field of vision. However, they
make objects in the mirror appear smaller and
farther away. When using these mirrors to es-
timate your distance to vehicles behind you
when changing lanes, you could estimate in-
correctly, which increases the risk of an acci-
dent.

@) Note
— Applies to: vehicles with power folding out-
side mirrors: If the mirror housing was
moved by force (for example, by running in-
to an object when maneuvering the vehicle),
the mirror must be folded all the way in us-
ing the power folding function. The mirrors
will make a loud noise when they latch into
place. The mirror housing must not be
moved back into place by hand because this
could impair the function of the mirror
mechanism.
— Applies to: vehicles without power folding
outside mirrors: If the mirror housing was
moved by outside forces (such as by an im-
pact while maneuvering), you must move
the mirror housing back into place by hand.
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Never fold power folding exterior mirrors*
by hand. Only fold them in and out using
the power controls.
G) Tips
— Certain settings are stored automatically in
the active personal profile.
— If the power adjusting function malfunc-
tions, the glass in both mirrors can be

adjusted by pressing on the edge of it by
hand.
Dimming the mirrors
> The interior and exterior mirrors* dim automat-
ically when light shines on them, for example
from headlights on a vehicle behind you.

ZX WARNING
— If the glass on an automatic dimming mir-
ror* breaks, electrolyte can leak out. This
liquid can irritate the skin, eyes and respira-
tory system. If there is contact with the flu-
id, flush immediately with plenty of water.
Consult a physician if necessary.
— Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the air-
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi-
cle or, if this is not possible, open all of the
doors and windows as wide as possible.
— If electrolyte fluid comes into contact with
the eyes, flush them thoroughly with plenty
of clean water for at least 15 minutes and
then seek medical attention.
— If electrolyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes, and then
clean with soap and water and seek medical
attention. Clean affected clothing and shoes
thoroughly before wearing again.
— If the fluid was swallowed and the person is
conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro-
fessionals. Seek medical attention immedi-
ately.



Q) Note
If the glass on an automatic dimming mirror*
breaks, electrolyte can leak out. This liquid
damages plastic surfaces and paint. Clean
this liquid as quickly as possible, for example
with a wet sponge.

— If the light reaching the rearview mirror is
obstructed, the automatic dimming mirror*
will not function correctly.
— The automatic dimming mirrors* do not dim
when the interior lighting is turned on or re-
verse gear is selected.

manually switching the wipers on based on
visibility
conditions.
— The windshield must not be treated with
water-repelling windshield coating agents.
Under unfavorable conditions, such as wet-
ness, darkness, and when the sun is low,
these coatings can cause increased glare,
which increases the risk of an accident. They
can also cause wiper blade chatter.
— Properly functioning windshield wiper
blades are required for a clear view and safe
driving > page 69, Cleaning/changing wip-
er blades.

() Note
— If there is frost, make sure the windshield
wiper blades are not frozen to the wind-
shield. Switching on the windshield wipers
when the blades are frozen to the wind-
shield can damage the wiper blades.
— Prior to using a car wash, the windshield
wiper system must be switched off (lever in
position @). This prevents the wipers from
switching on unintentionally and causing
damage to the windshield wiper system.
G) Tips
— The windshield wipers switch off when the
ignition is switched off. You can activate the
windshield wipers after the ignition is
switched on again by moving the windshield
wiper lever to any position. The single wipe
function (lever in position @)) also functions
when the ignition is switched off.
— Worn or dirty windshield wiper blades result
in streaking. This can affect the rain sensor >
