Appl ies to: veh icles w ith Audi adaptive light
Adaptive light provides bette r visibili ty when i t is
dark by adapting the ligh ts to the road condi tions
based on speed, such as on e xpressways, rura l
roads, at intersections, and in curves. The adap­
t ive lights only function when the light switch is
in the AUTO* posit ion and the all weather lights
are switched off .
A WARNING

- Automatic headlights * are on ly intended to
assis t the dr iver. They do not relieve t he
d river of respons ibi lity to check the head­
lights and to turn them on manua lly based
on the cur re nt ligh t and v isibility condition s.
For e xamp le, fog cannot be detected by the
light senso rs . So always switch on the low
beams under these weather con dit ions an d
when dr iv ing in the dark

once you drive forwa rd faster than 9 mph
(15 km/h) or turn the ignition off.
A WARNING ~
Cu rved mirror surfaces (for example convex)
enlarge the field of vision. However, they make objects in the mirror appear smaller
and farther away. Your may est imate incor­
rect ly when you use these mirrors to gauge
your distance from the veh icles beh ind you
when chang ing lanes, which increases the risk
of an accident .
(D Note
-Applies to vehicles with power folding exte­
rior mirrors : if the m irro r hous ing was
moved by outs ide forces (such as an impact
w hen maneuve ring), you must use the pow-
er folding function to fold the mirro r all the
way out. The mirrors will make a loud noise
when they latch into place. The mirror hous-
ing must not be moved back into p lace by

hand because this would impair the func­
tion 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.
(D) Tips
If the power adjustment fails, both mirrors
can be adjusted by hand by pressing on the
edge of the mirror surface.
Dimming the mirrors
Your vehicle is equipped with a manual or auto ­
matic* dimming rearview mirror .
Manual dimming rearview mirror
• Pull the lever on the bottom of the mirror back .
Automatic dimming mirrors*
• The interior and exterior mirrors dim automati­
cally when light shines on them, for example
from headlights on a vehicle behind you.
& WARNING
Applies to: vehicles with automatic dimming rearview
mirror
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
doors and windows as wide as possible.

-
- If electrolyte fluid enters the eyes, flush
them thoroughly with a large amount 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 at­
tention. 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.

- If there is frost, make sure the windshie ld
wiper blades are not frozen to the wind­
sh ield. Switching on the windshield wipers
when the blades are frozen to the wind­
shield can damage the wiper blades.
- The windshield wiper system must be
switched off (lever in position @) before
us­
ing a car wash. This prevents the wipers
from sw itching on unintentionally and caus­
i ng damage to the w indshield wiper system.

fun ct ion . Check your windshield wiper
blades regularly .
- The washer fluid nozzles in the w indshield
washer system are heated* at low tempera ­
tures when the ignition is on.
