A WARNING
- T he rain sensor is only intended to assist the
driver. The driver may still be responsible
for manually switching the w ipers on based
on v is ibility conditions.
- The w indshie ld may not be treated with wa­
ter -repelling windshield coating agents. Un­
favorable conditions, s uch 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 poss ible.
- Properly functioning windsh ield wiper
blades are required for a clear view and safe
dr iv ing to red uce the risk of an accident
Light s and Vision
c::> page 58, Changing windshield wiper
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 w iper blades.
- Prior to using a car wash, the windshield
wiper system must be sw itched off (lever in
position
0). This prevents the wipers from
switching on unintentionally and caus ing
damage to the windsh ield wiper system.
@ Tips
- The windshield wipers switch off when the
ign ition is switched off. You can activate the
w indshield wipers after the ignition is
switched back on by moving the w indshield
w iper lever to any position.
- Wor n or dirty w indshie ld w iper blades resu lt
in st reaking. T his can affect the rain senso r
function. Check your windshield wiper
blades reg ularly.
- The washer fluid nozz les for the windshield
washer system are heated a t low tempera­
tures when the ignition is on .
- Whe n stopping tempo rar ily, such as at a

General information
Appl ies to: ve hicles with Audi adaptive cruise co ntro l
Fig. 90 Fro nt o f th e ve hicle : sensor s and video c amer a
The areas wi th the radar and ul trasonic senso rs
and the video camera¢
fig. 90 must not be cov­
ered by stickers, deposits or any other objects ,
because this can interfere with the adaptive
cruise control function. For information on clean­ ing, refer to¢
page 337. The same applies for
any modifications made in the front area .
In some driving situations , the adaptive cruise
control function is restricted:
- Vehicle s can only be detected when they are
within the sensor detection zones
¢ page 96,
fig . 89 .
-The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle or moving into your lane .
Assist
-Objects that are difficult to detect such as mo­
torcycles, v ehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curv es
c!;> pag e 98.
- When the vehicle is stationary ¢ page 98.
A WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on .
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you . The driver must always take action to
avoid a collision . The driver is always responsi­
ble for braking at the correct time .
- For safety reasons, do not use adaptive
cruise 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 risk of an ac­ cident.
- Switch adaptive cruise control off tempora­ rily when driving in turning lanes, on ex­
pressway exits (except if predictive control
is switched on) or in construction zones.
This prevents the vehicle from accelerating
to the stored speed when in these situa ­
tions .
- 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 obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function .
-Adaptive cruise control does not respond to
people, animals, or crossing or oncoming
objects.
- 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.

Audi pre sense
Introduction
Applies to: ve hicles with Audi pre sense
W ith in the lim its of the system, t he pre sense
f u nctions can init iate measures in part icularly
dangerous sit uat ions to protect t he ve hicle pas ­
sengers and ot her road users.
- Because different veh icle systems such as the
ESC are i nterconnected , the
pre sense b asic in ­
t roduces p reempt ive safety meas ures for the
Assist
passengers i f an unstable driving si tuation is
detected.
- The
pre sen se front system uses the data from
the adaptive cruise contro l* radar sensors and
the camera to ca lculate the probability of a co l­
lision . With in the lim its of the system, an im­
pending co llision with vehicles can be detected
in both urba n and rural speed ranges. In t his
case, the system warns the driver visua lly,
acoust ica lly and w ith a jerk on the brakes if nec­
essary. If needed, i t can in itiate a partia l o r fu ll
dece lerat ion to reduce the collision speed or to
avoid the collision under certa in circumstances.
I n conjunction with pre sense basic/rear, the
front safety belts are a lso reve rsibly tens ioned
when needed . The pre sense front is a lso active
when adaptive cruise control* is sw itched off.
- Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra ­
dar sensors and ca lculates within the limits of
the system the probability of a rear end colli­
sion with t he vehicle behind you. Pre sense rear
is also act ive when side assist* is sw itched off .
- Within the limits of the system,
pre sense city
uses the camera data and can detect an im­
pe nding collision with vehicles and pedestrians.
I n th is case , the system warns the driver visua l­
ly , acous tic ally and wit h a jerk on the b rakes if
necessary. If needed, it c an initi ate a full dece l­
erat io n to reduce the collis io n speed or to avoid
the collision under certain circumstances . In
conjunction with pre sense basic/rear, the front
safety belts are a lso reversibly tens ioned when
needed .
A WARNING
-

increasing force within the limits of the
system
l)_ This reduces the vehicle speed in the
event of a collision. At low vehicle speeds, pre
sense front can initiate a complete deceleration
shortly before a collision with a vehicle driving
ahead
1>. If pre sense front determines that you
are not braking strongly enough when a collision
is imminent, it can increase the braking force .
The following functions trigger in conjunction
with pre sense basic/rear at corresponding vehi ­
cle speeds :
- Reversible tensioning of the front safety belts.
- Closing the windows and sunroof*.
- Inflating the side bolsters* in the seat backrest
and seat surface.
Audi drive select*: the reversible belt tensioner,
the closing of the windows and sunroof* as well
as the inflating of the side bolste rs* on the seat
backrest and seat surface are not active depend­
ing on the mode selected .
Collision avoidance assist
Collision avoidance assist helps you to steer the
vehicle around an obstacle in a critical situation.
If you avoid an obstacle after the acute warning,
then the collision avoidance supports you by ap­ plying slight steering adjustment to correct your
steering wheel angle as long as you are actively
steering. Collision avoidance assist is available at
speeds between approximately 20 mph (30 km/
h) and 90 mph (150 km/h).
Turn assist
When starting 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 intervention causes your vehicle to stay
in its lane.
.8, WARNING
-Pre sense front cannot overcome the laws of
physics.
It is a system designed to assist and

it cannot prevent a collision in every circum­
stance. The driver must always intervene.
The driver is always responsible 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 collis ion.
- 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 objects that are crossing the vehi­
cle 's path or that are difficult to detect

in General information on page 97.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collision risk.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense front can be impaired
by this. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their func­
tion.
(D Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably 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.
- Certain pre sense front functions are switch­
ed off when the ESC is limited or switched
off

Audi pre sense city
' Description
App lies to : vehicles wit h 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 a speed of 6 mph (9 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 possible at speeds
up to 50 mph (85 km/h).
Warnings
App lies to: vehicles wit h Aud i pre sense city
The system recognizes various dangerous situa­
tions. The
early warning occurs when:
- a vehicle driving ahead brakes sudden ly,
- your own vehicle approaches a sign ificantly
slower vehicle or stationary vehicle in the direc­
tion of travel.
- a pedestrian is standing in the lane or is moving
into the lane.
When this warning occurs, it may only be possi­
ble to avo id a collision by swerving or braking
strongly. The message

Additionally, a jerk on the brakes may occur as an
acute warning when there is an impend ing colli­
sion . If you do not react to the acute warning, pre
sense city can brake to the point of complete de­
ce leration within the limits of the system. This
reduces the vehicle speed in the event of a colli­
sion. The message

Audi active Lane assist
Description
Applies to: veh icles w ith Audi active lane assist
Active lane assist (lane departure warning) de­
tects lane ma rker lines withi n the l imits of the
system using a camera in the windshield. If you
are approaching a detected lane marker line and it appears likely that you will leave the lane, the
system will warn you w ith corrective stee ring .
You can override this steering at any time . If you
112
pass over a line, the steering wheel will vibrate
lightly. In order for this warning vibration to oc­
cur, it must first be switched on in the Infotain­
ment system. Active lane ass ist is ready for oper­
a tion when the lane marker line is detected on at
least one side of the vehicle .
T he system is des igned for driving on express­
ways and highways and therefore on ly activates
a t speeds above approximately 40 mph (65 km/
h) .
Applies to vehicles with s ide ass ist*: if you acti­
vate a turn signa l when active lane assist is ready
a nd it classifies a lane change as critical bec ause
of veh icles traveling a longside you or approach ­
i ng you, there will be noticeable corrective steer­
i ng shortly before you leave the lane. This will at­
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist* : the sys ­
tem does not warn when it is ready if you act ivate
the turn signal before crossing the lane marker
lin e. In this case, it assumes that you are chang­
in g lanes intent ionally.
Applies to vehicles with adaptive cruise contro l*:
there is no corrective steer ing or warnings if the
system recognizes a distinct passing maneuver.
If the conditions are met, congestion assist
switches on at speeds under approximately
40 mph (65 km/h)
¢page 104.
_& WARNING
-The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.

-Th e system has been unable to detect the lanes
for an extended period of time due to road con­
