@ Light switch
Turn the light switch @ to the corresponding po-
sition when the ignition is switched on. The 2
symbol and the selected position will turn on (ex-
cept position 0).
O - The daytime running lights* will automatical-
ly turn on. In vehicles for some markets, you can
switch the automatic daytime running lights on
and off in the MMI.
AUTO - The headlights will automatically adapt to
the surrounding brightness.
300: — Parking lights
20 - Low beam headlights
When the low beam headlights or parking lights
are switched on, the corresponding Be or 200 in-
dicator light will turn on depending on vehicle
equipment.
@ All-weather lights Zo
Requirement: the light switch must be in the AU-
TO or ZO position.
The headlights automatically adjust so that there
will be less glare, for example when the road sur-
face is wet.
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 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.

function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
The mirror surfaces tilt slightly when reverse
gear is selected to provide a better view, for ex-
ample of the edge of the curb.
You can adjust the mirror surface by turning the
knob in the desired direction.
The mirror moves from the reversing position
back to the original position:
— When you switch the ignition off
— When 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

Z\ 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 exte-
rior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must use the pow-
er folding function to fold the mirror all the
56
way out. The mirrors will make a loud noise
when they latch into place. The mirror hous-
ing 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
exterior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must move it back
in 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.
@) Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.
Dimming the mirrors

ZA WARNING
Applies to: vehicles with automatic dimming mirrors
— Electrolyte fluid can leak out from broken
mirror glass. This liquid can irritate the skin,
eyes and respiratory system. If there is con-
tact with the fluid, flush immediately with
plenty of water. Consult a physician if neces-
sary.
— 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

responding position:
@ Windshield wipers off
@ Rain sensor/intermittent mode. The wind-
shield wipers switch on once the vehicle speed
exceeds approximately 2 mph (4 km/h) and it is
raining. The higher the sensitivity of the rain sen-
sor that is set (switch © to the right), the earlier
the windshield wipers react to moisture on the
windshield. You can deactivate the rain sensor
mode, which switches the interval mode on. In
intermittent mode, you can adjust the interval
time using the switch ©.
> Applies to: MMI: Select on the home screen:

and afterwipes depends on how long the lever is
held in position ©).
The wipers wipe one time after several seconds of
driving to remove water droplets. You can switch
this function off by moving the lever to position
© within ten seconds of the afterwipe. The after-
wipe function is reactivated the next time you
switch the ignition on.
If you hold the lever in position ©) for longer
than half a second, the edge wiping feature will
be activated. This moves the windshield wipers
closer to the edge of the windshield and per-
forms an afterwipe to clean the residue that re-
sults from the wiping process from the edge of
the windshield. The function is available when
driving at speeds up to 75 mph (120 km/h).
The headlight washer system* operates only
when the low beam headlights are on. If you
move the lever into position ), the headlights
will be cleaned at fixed intervals.

Z\ WARNING
— The rain sensor is only intended to assist the
driver. The driver may still be responsible for
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 59, 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.
@) 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
function. Check your windshield wiper
blades regularly.
— The washer fluid nozzles for the windshield
washer system are heated when the ignition
is on if the outside temperature is low.
— When stopping temporarily, such as at a
traffic light, the speed of the windshield
wipers automatically reduces by one level.
