- The windshie ld may not be treated with wa­
ter-repelling windshield coating agents . Un­
favorable conditions, such as wetness, dark­
ness or low sun, can result in increased
glare, which increases the risk of an acc i­
dent . Wiper blade chatter is also possible.
- Properly functioning windsh ield wiper
blades are required for a clear view and safe
driving
¢ page 62, Replacing wiper
blades.
(D Note
- If there is frost, make sure the 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 position 0) before us-

General information
Appl ies to: ve hicles with Audi adaptive cruise contro l
Fig. 108 Fro nt of the vehicle: sensors and video camera
The areas with the radar and ultrasonic sensors
and the video camera
c:> fig . 108 must not be cov ­
ered by stickers, deposits or any other objects, because this can inte rfere with the adaptive
cr uise control funct ion. For information on clean­
ing, see
c:> page 354 . The same app lies for any
modifications made in the front area.
In some d riving situations, the adaptive cru ise
control funct ion is restr icted:
- Vehicles can only be detected when they are within the sensor detection zones
c:> page 108,
fig. 107.
- The system has a limited abil ity to detect
vehicles 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 clearan ce
or an overhanging load are detected late or not dete cted at all.
- When driving through curves
c:> page 110 .
-When the vehicle is stat ionary c:> page 110.
..&, WARNING
Always pay attent ion to the traffic aro und you
when adap tive cruise contro l is swi tched o n.
As the driver, you are s till responsible for your
own speed and the distance to other vehicles .
The adaptive cruise control is used to assist
you. The driver must a lways take action to
avoid a collision. The driver is a lways responsi­
ble for brak ing at the correct time.
A ss is ta nce syst ems
-For safety reasons, do not use adaptive
cru ise control when the road surface is in
poor condition and/or in bad weather condi­
tions (such as ice, fog, gravel, heavy rain and
hydroplaning). Using the system under
these conditions increases the r isk of an ac­
cident.
- Sw itch adaptive cruise control off tempora­
rily when dr iv ing in turning lanes, on ex­
p ressway ex its (except if predictive con trol
is switched on) or in const ruct ion zones.
This prevents the vehicle from acce lerating
to the stored speed when in these situa­
tions.
- The adaptive cruise contro l 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 obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function.
- Adaptive cr uise control does not respond to
peop le, animals, or crossing or oncoming
objects.
- The funct ion of the radar sensors can be af­
fected by reflective objects such as guard rails, the entrance to a tunnel, heavy rain or
ice.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check
the ir
f u nct ion.

Audi pre sense
Introduction
A pp lies to: ve hicles w ith Audi p re se nse
W ithin the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the veh icle pas­
sengers and other road users .
- Due to the interlinking of various vehicle sys­
tems, crit ical dr iving s ituations can be detected
by
pre sense basic and measures for preventa ­
tive occupant protection are can be initiated .
- The
pre sense front system uses the data from
the adapt ive cruise control* radar sensors and
the camera to calculate the probab ility of a col­
li sion. Withi n the limits of the system, an im­
pending collision with vehicles can be dete cted
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary. If needed, it can initiate a partial or full
deceleration to reduce the co llision speed or to
avo id the collision under certain c ircumstances .
In conjunct ion with pre sense basic/rear, the
front safety belts are also revers ibly tensioned
when needed . The pre sense front is also active
whe n adapt ive cruise control* is swit ched off.
- Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra­
dar sensors and calculates within the limits of
the system the probab ility of a rear end coll i­
s ion with the vehicle behind you. Pre sense rear
is also active when side assist* is switched off.
- Within the limits of the system,
pre sense city
uses the camera data and can detect an im ­
pending collision with vehicles and pedestrians.
In this case, the system warns the driver visual ­
ly, acoustically and with a jerk on the brakes if
necessary. If needed, it can initiate a full decel­
eration to reduce the collision speed or to avoid
120
the collision under certa in circumstances . In
conjunction with pre sense basic/rear, the front
safety belts are also reversibly tensioned when
needed .
A WARNING
-
Read the general information inc> & in Gen-
eral information on page 109,
c> & in Gener­
al information on page 130.
(D Tips
- Certain pre sense funct ions sw itch off when
dr iving in reverse.
- The pre sense functions may not be availa­
ble if there is a malfunct ion in the ESC sys­
tem or the a irbag control module.
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated .
- Switch the pre sense off when you are not
using public streets or when loading the ve­
hicle onto a vehicle carrier, tra in, sh ip or
other type of transportation. This can pre­
vent an undesired intervention from
the pre
sense system.
Audi pre sense basic
Description
App lies to : vehicles wi th Audi pre sense basic
The pre sense bas ic functions are activated at a
speed of approx imately 20 mph (30 km/h) or
higher .
The following functions can be triggered under certain condit ions w ith in the lim its of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy brak ing): the front safety belts
have reversib le be lt tens ioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- Closing the windows and sunroof* .
-

Ass is tan ce sys tems
your steering whee l ang le as long as you are ac­
tively steering. Evasive steering support is availa­
b le at speeds between approximately 20 mph
(30 km/h) and 90 mph (150 km/h).
Tu rn assist
When start ing to drive and up to speeds of maxi­
mum
6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning
left or right (available in certain countries). The
braking intervent ion causes your vehicle to stay
in its lane.
A WARNING
-Pre sense front cannot overcome the laws of
physics.
It is a system des igned to assist and
it cannot prevent a collision in every circum­
stance. The driver must always i ntervene.
T he driver is always responsib le for braking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This could increase your risk of a collision.
- The system can deploy incorrectly due to
system-specific limits .
- Please note that the sensors and the camera
do not always detect all objects or lane
markings. This increases the risk of an acci­
dent.
- Pre sense front does not react to people, an­
imals or ob jects that are crossing the veh i­
cle's path or that are difficu lt to
detect¢ .&.
in General information on page 109.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the fu nction of the radar sensors and
the system's ability to detect a coll is ion risk .
(D Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Pre sense front can be impa ired
by this. Have an authorized Aud i dealer or au­
thorized Audi Service Fac ility check their func­
tion.
l ) Th is is not availab le in some countr ies.
122
(D Tips
- You can cancel the braking with increas ing
force that is initiated by the system by bra k­
ing yourself, by acce lerating not iceably or
by swerving.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
- Specific pre sense front functions switch off
when the ESC is restricted or sw itched off

Audi pre sense city
Description
Applies to: vehicles with Audi pre sense city
Within the limits of the system, pre sense city
can warn you of impending collisions with
vehicles and pedestrians and initiate the applica­
ble braking maneuver if needed. Pre sense city is
active at speeds of approximately 6 mph (10 km/ h) and higher.
A pedestrian warning can occur at speeds up to
50 mph (85 km/h), and vehicle warnings can oc­
cur at speeds up to 155 mph (250 km/h) . A pre
sense city braking maneuver is poss ible at speeds
up to 50 mph (85 km/h).
Warnings
Applies to: vehicles with Audi pre sense city
The system recognizes various dangerous s itua­
tions. The
early warning occurs if:
- a vehicle driving ahead brakes suddenly,
- your own vehicle approaches a significantly
slower vehicle or stationary veh icle in the direc­
t ion of travel.
- a pedestrian is standing in the lane or is moving
i nto the lane .
When this warning occurs, it may only be possi­ ble to avoid a collision by swerving or braking
strongly. The message
