.&_ WARNING
-
-The rain sensor is only designed to assist
and support the driver.
It remains entire­
ly t he driver's responsibility to monitor
outside weather cond itions and to man­
ually activate the wipe rs as soon as rain
or drizzle reduces v isibility through the
windshie ld.
- The windsh ield must no t be treated w ith
wate r-repellent mate rials. They can in­
crease glare unde r poo r vis ibility condi ­
tions such as wetness, d arkness, or when
the sun is low on the hor izon. In addi­
tion, they can cause the w indshield w ip­
ers to chatter .
- Prope rly f unctioning windshield wiper
b lades are required for a clear view and
safe driving

windshield wiper blades.
(D Note
- In the case of frost, check whethe r th e
windshield wiper blades are frozen to
the windsh ield. Switching on the wind­
shield wipers can damage the wiper
blades!
- Pr ior to us ing a car wash, the w indshield
w iper system must be sw itched off ( lever
in posit ion @). Th is he lps to prevent un­
intentional switching on and damage to
the winds hield wiper system.
- Do not use the w ipers to clear a frosted
w indow . Us ing the wipers as a conven­
ient ice scrape r will destroy the wipe r
blades .
(D Tips
-The windshie ld w ipers are switched off
w hen the ignit ion is off . Activate the
w indshield wipers after the ign ition is
switched back on by moving the w ind­
shield wiper lever to any position.
- Worn or dirty windshield wipe r blades
result in streaking. This can affect the

rain sensor function. Check your
windshield wiper b lades regularly.
- The washer fluid nozzles of the wind­
sh ield washer system are heated at low
temperatures when the ignit ion is on .
- When stopping temporarily, e .g . at a
traffic light , the set speed of the wind­
shield wipers is automatically red uced by
one speed.

84 Audi ad apti ve cruise control and bra king gu ard
Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regu lat ing 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 90.
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. 83 Front of th e veh icle: senso rs and video camera
The areas that conta in the radar and ultrason­
ic sensors and the v ideo camera
c:::> fig. 83
must neve r be cove red by stic kers or other ob­
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to
c:::> page 210. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::> page 86, fig. 86.
- The system has a limited ability to detect
objects that are a short d istance 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 all.

& WARNING
A lways pay attention to traffic when adap ­
tive cruise contro l is switched on and brak­
ing g uard 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 a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cruise 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 registered by the radar sensors,

Audi adapt ive crui se c ontrol an d bra kin g guard 85
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 be ing 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 le r or a u­
thorized Audi Serv ice Facility check their
funct ion.

Audi braking guard
Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 93 Instrument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the limits 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 vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Brak ing
guard does not react if it cannot detect the
situation.
The system advises you of various situations:
- The
distance 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 collision . The indicator
light
I in the display comes on .
- The
approach warning is given when a de­
tected veh icle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. Th e indicator
light
I and indicato r in the display will warn
you about the danger¢
fig. 93. You will a lso
hear an acoustic signal.
ll This is not ava ilable in some co un tri es .
If you do not react fast enough or do not react
at all to the situation, braking guard will inter·
vene by braking.
- If a coll is ion is imminent, the system will
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake wit h increas ing
force w ith in the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
short ly before a collision
1l . Full deceleration
at high speeds occurs only in vehicles with
adapt ive cruise control and side assist (pre
sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is im·
m inent, it can increase the braking force.
- The pre sense functions also engage when a
collision is imminent¢
page 192.
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
¢ page 91, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, oth­
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always respons ible for braking at the cor­
rect time.
- Always pay close att ent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take comp lete control whenever necessa­
ry . Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead.
- Braking guard works within limits and
will not respond outside the system lim· its, for example when approaching a ..,.

Audi adaptive cru ise control and brakin g guar d 91
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar 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 in cl ud ing crash barr i­
ers or tunnel ent rances may impair the
function of the radar sensor.
(D Tips
- You can ca ncel the braking w ith increas­
i ng force that is initiated by the system
by b raking yo urself, by accelerating no­
ticeab ly or by swerving.
- Bra king guard error messages
¢page 91.
- Keep in m ind that braking guard can
brake unexpectedly. Always secure any
c ar go or objec ts that you are transpor t­
i ng to reduce the risk of damage or in­
ju ry.

In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The fas ter a vehicle ap­
p roaches, the sooner the display in the exteri­
or m irror will t urn on.
@ V ehicles traveling with you
Vehicles traveling w ith you are indicated in the

© Vehicle s 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
15 km/h), the display in the exterio r mirror
turns on as soon as the vehicle enters your blind spot.
The disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the veh icle and your
vehicle is greater than 9 mph or 15 km/h).
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 your
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lane 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¢
fig. 101 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer. For
i nformation on cleaning, refer to ¢
