(I) -Rain sensor mode. The windshield wipers
switch on once the vehicle speed exceeds ap­
proximately 2 mph (4 km/h) and it is raining.
The higher the rain sensor sensitivity is se t
(switch @to the right), the earlier the wind­
shield wipers react to moisture on the wind­
shield. You can deactivate rain sensor mode in
the MMI, which will then activate intermittent
mode. Select:
ICARI function button > (Car)*
systems control button > Driver assist> Rain

posi tion longer, the wipers switch from slow
wiping to fast wiping .
® - Clean the windshield . The wipers wipe
one time after several seconds of driving to remove water drople ts. You can switch this
function off by moving the lever to position ®
within 10 seconds after the afterwipe . The af­
terwipe function is reactivated the next time
you switch the ignition on.
Cleaning the headlights*. The headlight wash­
er system* operates only when the headlights

camera* are washed in intervals.
.&_ WARNING
-
- The rain sensor is only designed to assist
and support the driver.
It remains entire­
ly the driver's responsibility to monitor
outside weather conditions and to man­
ually activate the wipers as soon as rain
or drizzle reduces visibility through the
windshield.
- The windsh ield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
- Properly functioning windshield wiper
blades are required for a clear view and
safe driving
q page 47, Replacing
windshield wiper blades.
(D Note
- In the case of frost, check whether the
windshield wiper blades are frozen to
the windshield. Switching on the wind­
shield wipers can damage the wiper
blades!
- Prior to using a car wash, the windshield
wiper system must be switched off (lever
in position @). This helps to prevent un­
intentional switching on and damage to
the windshield wiper system.
- Do not use the wipers to clear a frosted
window . Using the wipers as a conven­
ient ice scraper will destroy the wiper
blades .
(D Tips
-The windshield wipers are switched off
when the ignition is off . Activate the
windshield wipers after the ignition is
switched back on by moving the wind­
shield wiper lever to any position.
- 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 of the wind­
shield washer system are heated at low
temperatures when the ignition is on.
- When stopping temporarily, e.g. at a traffic light , the set speed of the wind­
shield wipers is automatically reduced by
one speed.

are extremely dirty, you can also clean
them with a soft sponge or cloth.
- For your safety, you should replace the
wiper blades once or twice a year. See
your authorized Audi dealer for replace­
ment blades.
(D Note
- The windshield wiper blades must only
be folded away when in the service posi­
tion! Otherwise, you risk damaging the
paint on the hood or the windshield wip­
er motor.
- You should not move your vehicle or
press the windshield wiper lever when
the wiper arms are folded away from the
windshield. The windshield wipers would move back into their original position
and could damage the hood and wind­
shield .
- To help prevent damage to the wiper sys­
tem, always loosen blades which are fro­
zen to the windshield before operating
wipers .
- To help prevent damage to wiper blades, do not use gasoline, kerosene, paint
thinner, or other solvents on or near the
wiper blades .
- To help prevent damage to the wiper
arms or other components, do not at­
tempt to move the wipers by hand.

control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regulating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system .
If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac ­
celerate your vehicle. This helps to make driv­
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 88.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them
properly at all times.

Fig. 82 Front of the veh icle: sensors and video camera
The areas that conta in the radar and ultrason­
ic sensors and the v ideo camera
c:::> fig. 82
must never be cove red by stic kers or other ob­
jects or obstructed with dirt, insects, snow or
ice that will interfere w ith the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to
r:;, page 211. The same applies
for any modifications made in
the front area.
T he function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ithin sensor range
c:::> fig . 85.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of veh icles are hard to detect;
for examp le motorcycles, veh icles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at al l.

& WARNING
A lways pay attention to traffic when adap­
tive cruise contro l is switched on and brak­
ing guard is active. As the driver, you are
still respons ible for starting and for main­
taining speed and distance to other ob­
jects. Braking guard is used to assist you .
The dr iver must always take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking at the correct time.
- Improper use of adaptive cru ise control
can cause collisions, other acc idents and
serious personal injury.
- Never let the comfort and convenience
that adaptive cruise control and braking
gua rd offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
hicle at a ll times,
- Always remember that the adaptive
cr uise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled o r disabled vehicle.
I f re gistered by the radar sensors,

Audi adapt ive crui se c ontrol an d bra kin g guard 8 3
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the video camera, an acute col­ lis ion warn ing.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these cond itions cou ld result in a co lli ­
sion .
- Switch adaptive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones . This prevents the vehicle from ac­
celerating to the set speed when in these
situations .
- The adapt ive cru ise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­ ride the speed and distance regulation .
- When approaching stationary objects such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people , an­
ima ls, objects crossing the road o r on­
coming objects .
- The function of the radar sensors can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
heavy rain or i ce.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
conditions .
- To prevent unintended operation, always
switch ACC off when it is not being used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and underbody. That cou ld affect the adaptive
cruise control system and brak ing guard .
Have your authorized Aud i dea ler or a u­
thorized Audi Serv ice Facility check their
funct ion.

Descript ion
App lies to vehicles: with Audi adap tive cruise control
F ig . 92 Instr ument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the lim its of
the system when adapt ive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approachi ng a veh icle up
ahead that is moving more slowly . Bra king
g ua rd does not react if it cannot detect th e
situ ation .
The system advises you of various situations:
- The
distan ce warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will not be able to avoid a coll is io n. The indicator
li ght
I in the display comes on .
- The
approach warning is g iven when a de­
tected veh icle up ahead in yo ur lane is mov ­
i ng much more slowly than you are o r if it
brakes sha rply . W hen this wa rning is given,
it m ay only be poss ible to avoid a collision

A WARNING
-
Lack of attentio n can cause collisions, oth-
er accidents and serio us pe rsonal injuries.
Th e braking gua rd is an ass ist system and
ca nnot prevent a collision by it self. T he
dr ive r m ust always intervene. The dr ive r is
a lways res ponsib le f or br ak ing at the cor­
r e ct t ime.
- Always p ay clo se a ttent ion to traff ic,
even when the braking guar d is swi tched
o n. Be ready to in tervene and be ready to
take comp lete contro l whenever necessa­
ry. Always keep the safe and legal dis ­
tance between your ve hicle and veh icles
up ahead.
- Braking guard works within limits and
w ill not respond outside t he system lim­
its, for examp le w hen approachi ng a
stopped vehicle or stati onary obstacle ..,.

- Alw ays remember that the radar sensor
for the b raking guard works only within
defined detection and ra nge limits that
may prev ent the proper det ection of oth­
er ve hicles.
- The ra dar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent rances may impair the
function of the radar sensor.

@ Veh icles left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph or

Functi onal limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the d isp lay in the exterior mirror may
turn on even though there is no veh icle locat­
ed in the area that is cr itical for a lane change.
For example:
- if the lanes are narrow or if your are dr iving
on the edge of your lane.
If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to you r
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lan e ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors with stickers,
deposits, bicycle wheels or other objects, be­
cause this will affect the function . Do not use
s ide ass ist when towing a trailer . For informa­
tion on clean ing, refer to
