94 Audi adaptive cruise control and braking guard
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 regulat 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 he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers¢
page 100.
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.
General information

Applies to vehicles: with Audi adaptive cruise co ntrol
Fig. 103 Fro nt of the vehicle: Position of radar senso r
The area that contains the radar sensor
¢
fig . 103 must never be cove red by stickers
or other objects or obstructed with dirt, in­
sects, snow or i ce that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
¢
page 198. The same applies for any modifi­
cations made in the front area . T
he function of the adaptive cruise cont rol
system and braking guard is limited under
some condit ions:
- Objects can only be detected when they are
within sensor range
¢fig . 106 .
-The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehicle or moving into
your lane.
- Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles 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¢
page 95.
-Stat ionary objects ¢ page 95.
A WARNING
-
Always 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
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a col lision. The driver is always responsible
for braking at the correct time.
- Im proper use of adaptive cruise con trol
can cause collisions, other accidents and
serio us personal injury.
- Never let the comfor t and convenience
that adaptive cruise control and braking
guard offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cru ise contro l and brak ing guard have
lim its -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 or disabled vehicle.
If registered by the radar sensor, vehicles
or obsta cles that are not moving can
trigger a co llision warning and if

Audi adapt ive crui se c ontrol an d bra kin g guard 95
confirmed by the video camera, an acute
collision warning.
- 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
hydroplan ing). Using the system under
these conditions cou ld result in a co lli­
sion.
- Switch adaptive cruise control off tempo­ rar ily when driving in turning lanes, on
expressway exits or in cons truction
zones. This prevents the vehicle from ac­ celerating to the set speed when in these
situations.
- The adaptive cr uise control system wi ll
not brake by itse lf if you p ut your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation .
- When approaching stationary objects
such as stopped traff ic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects.
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safely. The
adaptive cruise cont ro l cannot slow or
brake the veh icle safely when you follow
ano ther veh icle too closely. Alway s re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
condit ions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, whee l housing and
underbody . That could affect the adaptive cruise control system and braking g
uard.
Have your authorized Audi dea ler o r au­
thorized Audi Service Facility chec k their
funct ion.

if a ve hicl e@ , which has already been detec t­
ed by the adaptive cru ise con trol , turns or
changes lanes and another stationa ry vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

Fig. 106 Detect ion range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunc­
tion with a radar sensor installed in the front
of the vehicle
c::> fig. 103, which is subject to
des ignated system limits
c::> page 96. Station­
a ry objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control works like a regu lar cruise control sys­
tem. The stored speed is main tained. When
approaching a moving vehicle detected up
ahead, the adaptive cruis e control system au­
tomatically s lows down to match that vehi­
cle's speed and then maintains the distance
that the driver previous ly stored. As soon as
the system does not detect a vehicle up
ahead, adaptive cruise control accelerates
back up to the stored speed .
Which functions can be controlled?
When you switch adaptive cruise contro l on,
you can set the current speed as the "control
speed"
c::> page 96, Switching on and off.
When driving, you can stop cruise control
c::> page 98 or change the speed c::> page 9 7
at any time.
You can a lso set the distance to the object
ahead and set the adaptive cruise control driv ­
i ng program

Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approach warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise control is switched off .
What can Audi 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 . Braking
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 vehicle up ahead in your lane is mov­ ing much more slowly than you are or if it
brakes sharply . When th is warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply . The indicator
l ight
I and indicato r in the display will warn
you about the danger
¢ fig. 113 . You will al­
so hear an acoustic signal.

- If a coll is ion is imminent, the system wi ll
fi rst provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake within the lim its of
the system. This reduces the vehicle speed
in the event of a collision .
- At speeds under 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration

).
- If the braking guard senses that you are not
brak ing hard enough when a co llision is im­
minent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or MMI
¢ page 101, Settings in the radio/
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 dr iver is
always responsible for braking at the cor­
rect 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 complete 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 examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in t raffic).

Audi adaptive cru ise control and brakin g guar d 101
-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 includ ing crash barr i­
ers or tunnel ent ran ces may impair the
function of the radar sensor.
- You can cance l the braking that is initiat­
ed by the system by braking yourself, by
accelerating noticeab ly or by swerving.
- Bra king guard error messages

Fo r example:
- if the lanes are narrow or if your are driving
on th e edge of your lane. If this is the case,
the system may have detected the vehicle in
another la ne that is
not adjacent to you r
cur rent lane .
- if you a re driving throug h a c urve . Side assist
may react to a vehicle that is one lane ove r
from the ad jacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist
fu nctions are limited .
Do not
