When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer­ing wheel angle. This provides better lighting
through the curve. The system operates in a
speed range from approximately 6 mph (10 km/
h) to 68 mph (110 km/h).
Static cornering light* (vehicles with adaptive
light) -the cornering light switches on automati­
cally when the steering wheel is turned at acer­
tain angle at speeds up to approximately 44 mph
(70 km/h) and when the turn signal is activated
at speeds up to approximately 25 mph (40 km/
h). The area to the side of the vehicle is illuminat­
ed better when turning.
Speed dependent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways . Intersec­
tions can also be illuminated on vehicles with a
navigation system* .
Highway light function*
(Vehicles with adaptive light or LED headlights) -
This function adapts the lighting for highway
driving based on vehicle speed .
& WARNING
-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 accord­
ing to the current light and visibility condi­
tions. For example, fog cannot be detected by the light sensors . So always switch on the
low beam under these weather conditions
and when driving in the dark
io.
-Accidents could occur if you cannot see the
road ahead of you well and if others on the
road cannot see you . Always switch your
headlightsonsothatyoucanseetheroad
ahead of you and others can see your vehicle
from behind.
- The rear fog lights should only be turned on
in accordance with traffic regulations, to
prevent glare for traffic behind your vehicle .
-If the battery has been discharging for a
while, the parking lights may switch off au­
tomatically to conserve the battery charge

for the next time the engine is started. Al·
ways make sure your vehicle complies with
legal regulations regarding sufficient and
safe lighting when parking it. Avoid using
the parking lights for several hours.
- Please observe legal regulations when using
the lighting systems described .
@ Tips
-The light sensor for the automatic head­
lights* is in the rearview mirror mount.
Therefore, do not place any stickers in this
area on the windshield.
- Some functions of the exterior lighting can
be adjusted
¢ page 48 .
-If you turn off the ignition while the exterior
lights are on and open the door, you will
hear a warning tone.
- In some market-specific versions, the tail
lights do not turn on when switching on the
daytime running lights .
- In cool 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.
- A message will appear in the instrument
cluster if there is a malfunction in the light
sensor

- The rain sensor is only intended to assist the
driver . The dr iver is still responsible for
manually switching the w ipers on accord ing
to the v is ibility conditions .
- The windshield may not be treated with wa­ ter-repell ing windsh ield coating agents . Un­
favorable conditions, such as wetness, dark­
ness , or when the su n is low , can cause a
st rong glare, w hich increases t he risk of an
accident. W iper blade chatte r is a lso possi ­
ble.
- Properly f unction ing windsh ield wiper
blades are required fo r a clear view and safe
dr iving
c:> poge 53, Replacing front wind­
shield wiper blades .
CD Note
-If there is frost, make sure t he windshie ld
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.
- The windshield wiper system must be
switched off ( lever in pos ition 0) before us­
i ng a car wash . This prevents unintentional
switching on and damage to the w indshield
wipe r system .
- Do not use the wipers to remove ice from
the windows . Us ing windsh ield wipers as ice
scrapers destroys the wiper blades .
(D Tips
-The windshield wipers switch off when the
i gnition is turned off. You can activate the
windsh ield wipers after the ign it ion is
switched back on by moving the winds hield
wipe r lever to any pos it ion.
- Wo rn o r dirty windshield wipe r blades result
i n strea king . This can affec t the ra in sensor
f u nct io n. Check yo ur windshield wipe r
blades regu larly.
- The washe r fluid no zzles in the w indshie ld
washer system are hea ted* at low tempera­
tures when the ignition is on.

General information
Appl ies to vehicles: with Audi adaptive cruise contro l an d Audi
p re se nse front
Fig. 116 Front o f ve hicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*¢
page 139.
The radar sensor area¢ fig. 116 must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap­
tive cruise control and the pre sense front. For in­
formation on cleaning, refer to
c:> page 2 74. The
same applies for any modifications made in the
front area .
The function of the adaptive cruise control sys­ tem and pre sense front is limited in some condi­
tions :
- Objects can only be detected when they are
within the sensor range
¢ page 132, fig. 115.
- The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the side of your vehicle or moving into your lane.
- Objects that are difficult to detect such as mo ­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not detected at all.
- When driving through curves
c:> page 134.
-With stationary objects c!;> page 134.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
c:> page 139 . As the driv­
er, you are still responsible for starting and
for maintaining speed and distance to other objects. The pre sense front is used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi­ ble for braking at the correct time.
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing) . Using the system under these condi­
tions could result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations.
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and pre sense front will
have limited function.
- The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob­
jects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice .
- Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely . The adaptive cruise con­
trol cannot safely slow your vehicle or brake it to a stop if you are driving too close be­
hind a vehicle. Please note that the auto­
matic braking function cannot brake sud­
denly or apply the brakes fully under these
conditions.
- To reduce the risk of unintended actions,
switch the ACC off when you a re not actively
using it.

Assist
(D Note
The sensor can be displaced by impacts or
damage to the bumper , whee l housing and
underbody. The adaptive cruise control and
pre sense front may become impaired as a re­
sult . Have an authorized Audi dealer or au­
thorized Audi Service Fac ility check their func­
tion .

Fig. 117 Example: driving into a curve
When driving into a curve ¢fig. 117 and out of a

objec t in the neighboring lane and apply the
brakes. You can prevent that by pressing the ac­
celerator pedal briefly .

Adaptive cruise control
The adaptive cruise control system only reac ts to
objects that are moving or that the system has
already detected as moving. For example, if a de­
tected vehicle @turns or changes lanes, the
adaptive cruise contro l will not react to a stopped
vehicle @. Press the brake pedal to slow your ve­
hicle down.
