Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise contro l system assists the
driver by regulating vehicle speed and helping to
maintain a set distance to the veh icle 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
c::> page 90.
Adaptive cruise control and braking guard have
technical limitations that you must know, so
please read this section carefully, understand
how the system works and use them properly at
all times.

Fig. 88 Front of the ve hicle: sensors and video camera
The areas that contain the radar and ultrasonic
sensors and the video camera
c::> fig. 88 must nev­
er be covered by stickers or othe r objects or ob­
structed with dirt, insects, snow or ice that will
interfere with the adaptive cruise control system
and braking guard. For information on cleaning,
84
refer to c::> page 203. The same applies for any
modifications made in the front area .
The function of the adaptive cruise control sys­
tem and braking guard is limited under some
conditions:
- Objects can only be detected when they are
w ithin sensor range
c::>page 86, fig. 91.
- Th e system has a limited ability to detect ob­
jects that are a short distance ahead, off to the
side of you r vehicle or moving into your lane .
- Some kinds of vehicles are hard to detect; for
example 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.
- When driving through curves

-Stationary objects c::> page 85.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you. The driver must
always take act ion to avoid a collision . The
driver is always respons ible for braking at the
correct time.
- Improper use of adaptive cruise control can cause collisions , other accidents and serious
personal injury.
- Never let the comfort and convenience that
adapt ive cru ise control and braking guard
offe r dist ract you from the need to be alert
to traffic conditions and the need to remain
in fu ll contro l of your ve hicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will no t slow the vehicle down or maintain
the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a traff ic jam, a stalled or disab led vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a co llision warning and if confirmed by the
video camera, an acute co llision warning.

Audi ada pti ve c ruise contr ol and br akin g gu ard
-For safety reasons, do not use adapt ive
cruise contro l when driv ing 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) . Us ing the system under these condi­
t ions could result in a collision .
- Switch adaptive cruise contro l off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in const ruc tion zones. This
preven ts the vehicle from accelerating to
the set speed when in these situat ions .
- T he adapt ive cr uise con trol system will no t
br ake by i tself if you pu t your foot on the ac­
celerator peda l. Doing so can override the
speed and distance regulation.
- Whe n approaching stat ionary obje cts such
as stopped traffic, adapt ive cruise control
will not respo nd and braking guard will have
limited function .
- The adaptive cruise control system and
brak ing guard do not react to peop le, ani­
ma ls, objects crossing the road or oncom ing
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rai ls, t he entrance to a tunnel, heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safely . The adap­
t ive cr uise control cannot slow or brake the
vehicle safely when you follow another veh i­
cle too close ly. Always remember th at the
au tom atic b raking function ca nnot br ing the
vehicle to a sudden or emergency stop un­
der these conditions .
- T o preven t unintended operation, alw ays
switch AC C off when i t is not be ing used.
(D Note
The sensors can be displaced by impacts o r
damage to the bumper, whee l housing and
underbody. That co uld affect the adaptive
cru ise con trol sys tem and braking guard .
Have your a uthorized Audi dea ler or author·
ized Aud i Service Facility check their function.
In curves
Applies to vehicles: w ith Audi adapt ive cruise control
F ig. 89 Exampl e: d ri ving into a curve
When driving into a curve¢ fig. 89 and out of a
curve, the adaptive cruise control may react to an
object in the neighboring lane and app ly the
brakes . Yo u can prevent that by pressing the ac­
ce le rator peda l br iefly.
Stationary objects
Applies to vehicles : w ith Audi adaptive cruise control
Fig. 90 Exa mple : object changing la nes a nd s tatio nary ob ·
j e ct
T he adaptive cruise control system only reacts to
objects 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
tected @ turns or changes lanes, but adaptive
cruise control does not react to a stationary veh i­
cle @.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: w ith Audi adaptive cruise co ntro l
Fig. 98 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera . It also functions within the limits of the
system when adaptive cruise control is switched
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 vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly . Braking guard does not react if
it cannot detect the situat ion.
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 coll is ion. The indicator light.
in the display comes on .
- The
approach warning is given 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 avo id a collision by swerving or braking
sharp ly. Th e indicator light. and indicator in
the display will warn you about the danger
qfig. 98. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to t he situation, braking guard will intervene
by braking.
l ) Thi s is not ava ilab le in some co un tri es .
90
-If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
app lying the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake with increasing force with­
in the limits of the system. This reduces the ve­
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a co llision
1
) . Full deceleration at
high speeds occurs only in vehicles with adap­
tive cruise control and side assist (pre sense
plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent
qpage 184.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
q page 91, Settings in the Infotainment sys­
tem .
A WARNING
Lack of attent ion can cause collisions, other
accidents and serious personal injuries . The
b ra king guard is an assist 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 atten tion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
comp lete contro l whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works with in 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 brak ing guard works only within def ined Ill>

Audi adapt ive cruis e control and braking gua rd
de tect ion and range limits t hat may prevent
the proper detection of other veh icles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles up ahead may not be
promptly detected or may not be detected
at all .
- Reflective surfaces including crash barriers
or tunnel entrances may impair the funct ion
of the radar sensor.
(D Tips
- You can cancel the brak ing with increasing
force that is init iated by the system by b rak­
i ng yourself, by accelerat ing noticeab ly or
by swerving .

Audi side assist
-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.
- Side assist cannot detect all 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 mist .
- 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.
(D Tips
-If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be misin­
terpreted.
