manually switching the wipers on according
to the v is ibility conditions.
- The w indshield may not be treated w ith wa­
te r-repell ing windsh ield coating agents. Un­
favorable conditions, such as wetness, dark­ ness or low sun, can resu lt in increased
glare, which increases the risk of an acci ­
dent. Wiper blade chatter is also possible.
- Properly functioning w indshield w iper
blades are required for a clear view and safe

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehi cle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system.
If the system de­
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your vehi­
cle. This helps to make driving 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 maneu­
vers¢
page 91.
Adaptive cruise control and braking guard have
technica l limitations that you m ust know, so
p lease read this section carefu lly, understand
how the system works and use them properly at
all times.

Fig. 89 Front of th e veh icle: sensors and video camera
The areas that contain the radar and ultrason ic
sensors and the video camera ¢
fig. 89 must nev­
e r be covered by stickers or other objects or ob­
structed with dirt, insects, snow or ice that will
interfere with the adaptive cruise contro l system
and braking guard . For information on cleaning, refer to
¢
page 205. The same applies for any
modif ications made in the front area.
T he function of the adaptive cru ise contro l sys­
tem and braking guard is limited unde r some
conditions:
- Objects can only be de tected when they are
w ith in sensor range
¢page 87, fig. 92.
- The system has a limited ability to detect ob­
jec ts that are a shor t distance ahead, off to the
side of yo ur vehicle or mov ing into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, vehicles with high
ground clear ance or overhanging loads may be
detected when it is too late o r they may not be
detected at all.
-When driving through curves

_& WARNING
Always pay a ttent ion to traffic when adap tive
cr uise control is switched on and braking
guard is active. As the driver, you are sti ll re­
sponsib le for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you. The driver must
a lways take action to avo id a col lision . The
d river is always responsible for brak ing at the
correct t ime.
- Improper use of adaptive cruise control can cause collisions, other accidents and serious
pe rsonal inj ury.
- Never let the comfort and conve nience that
adapt ive cr uise control and b rak ing guard
offer distrac t you from the need to be alert
to traffic condit io ns and the need to remain
in full control of your veh icle at all times,
- Always remember tha t the adaptive cruise
con trol and bra king guard have limits -they
will no t slow the vehicle down or maintain
the set distance when you dr ive towards an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehicles
or obstacles that a re not moving can trigger
a collision wa rning and if confirmed by the
video came ra, an acute collision warning.

Audi adapt ive cru ise control and brak ing gu ard
- 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 hydrop lan­
ing). Using the system under these condi­
t ions could resu lt in a col lision.
- Switch adaptive cruise control off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situat ions.
- The adapt ive cr uise control sys tem wi ll not
brake by itself if yo u put you r foot on the ac­
celerator pedal. Doing so can ove rride the
speed and distance regulation.
- When approach ing stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking g uard will have
limited function.
- The adapt ive cr uise control system and brak­
ing guard do not react to people, animals,
objects cross ing 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.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly . The adap­
t ive cru ise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
automa tic brak ing funct ion c annot bring the
vehicle to a sud den or emergency stop un­
der these conditions.
- To prevent unin tended operation, always
switch ACC off when it is not be ing use d.
(D Note
The sensors can be displac ed by impacts or
damage to the bum per, whee l hou sing and
unde rbody. That could affe ct the adap tive
cruise contro l system and braking guard . Have
your authorized A udi dealer or authorized
Audi Service Facility c heck their function.

The adaptive cruise contro l system only reacts to
ob jects that are moving or that the system has
already detected as moving. For example, it can
react when a vehicle that has already been de­
t ec ted @ turns or changes lanes, but adapt ive
cruise control does not react to a stationary vehi ­
cle @.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 99 Instrument cluster : approach warning
Braking guard uses radar sensors and a video
camera. It also functions within the lim its of the
system when adaptive cruise control is sw itched
off.
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own veh icle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slow ly . Braking guard does not react if it
cannot de te ct 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 avo id a collision. The indicator light.
in the d isplay comes on .
- The
approach warning is g iven when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be pos­
sible to
avoid a co llis ion by swerving or braking
sharp ly. The indicator light. and indica tor in
the display will warn yo u about the danger
¢
fig. 99. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
M N by braking. <( I.J "". rl I.O
"' N <.0 ll This is not a vailable in some coun tri es. rl
- If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake with increasing force within
the limits of the system. This reduces the vehi­
cle speed in the event of a collision.
- The system can initiate maximum braking
short ly before a collision
1l . Full dece leration at
high speeds occurs only in vehicles with adap­
tive cruise control and s ide ass ist (pre sense
plus).
- If the braking guard senses that you are not
braking hard enough when a collis ion is imm i­
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imm inent ¢
page 185 .
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 92, Settings in the Infotainment sys­
tem .
A WARNING
--
Lack of attention can cause collisions, other
accidents and ser ious personal injuri es. The
braking guard is an ass ist system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always respon­
sib le for braking at the correct time.
- Always pay close attent ion to traffic,
even
when the braking guard is switched on . Be
ready to intervene and be ready to take com­
p lete control whenever necessary. Always
keep the safe and legal distance between
your veh icle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
example when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
-Always remember that the radar sensor for
the braking gua rd works on ly w ithin defined
liJ,,

Audi adaptive cru ise control and b ra king guard
detection and range limits that may prevent
the proper detect ion of other 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 detected
at all.
- Reflective surfaces includ ing crash barr iers
or tunnel entrances may impair the function
of the radar senso r.
@ Tips
- You can cance l the braking with increasing
force that is initiated by the system by brak­
i ng yourself, by accelerating noticeably or by
swervrng .

Fig. 107 Rear of the ve hicle: pos it io n of t he sensors
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
(D Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away . The faste r a vehicle approaches,
the sooner t he d isplay in the exter io r mirro r will
turn on.
@Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
98
are indicated by the time they enter your "blind
spot", at the latest.
@ Vehicles left behind
If you slowly pass a veh icle that side assist has
detected (the difference in speed between the ve­
hicle and your vehicle is less than 9 mph or 1S
km/h), the display in the exterior mirror turns on
as soon as the vehicle enters your blind spot.
T he display will not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph or 15 km/h).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In certain s ituations, the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area that
i s 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 anoth­
er lane that is
not adjacent to your current lane.
- if yo u are driving through a c urve . Side assist
may react to a vehicle that is one lane over from
the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar sensors
q fig. 107 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . Do not
use side assist when towing a trailer . For infor ­
mation on cleaning, refer to
q page 205 .
A WARNING
-Always pay attention to traffic and to the
area around your veh icle. S ide ass ist cannot
replace a dr iver's attention . The driver alone
is always responsible for lane changes and
sim ila r driv ing maneuvers.

M N <( I.J "". rl I.O
"' N I.O rl
-Improper reliance on the side assist system
can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes .
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Sid e assist cannot detect a ll vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, snow or heavy m ist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface . Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody. This can affect the system . Have
your authorized Audi dealer or authorized
Audi Service Facility check their function.
