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 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 . Th is 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
c::;, page 113.
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
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 114 Front of the vehicle: Position of radar sensor
The area that contains the radar sensor
c::;, fig. 114 must never be covered by stickers
or other objects or obstructed with dirt, in
sects, snow or ice that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c::;, page 219. The same applies for any modifi
cations made in the front area . The
function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
.:!>page 109 , fig. 117.
-The system has a limited ability to detect
objects that are a short distance 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
c::;, page 108.
-Stationary objects c::;, page 108.
A WARNING
-Always pay attention to traffic when adap-
tive cruise control is switched on and brak ing guard is active. As the dr iver, you are
still respons ible for start ing 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 collision. The driver is always responsible
for braking at the correct time.
- Improper use of adaptive cruise con trol
can cause collisions, other accidents and
serious personal injury .
- Never let the comfort and convenience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic conditions and the
need to remain in fullcontrolofyourve
hicle at all times,
- Always remember that the adaptive
cru ise contro l and braking guard have
limits -they will not slow 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
moving, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obstacles that are not moving can
trigger a collision warning and if .,.

108 Audi adaptive cruise control and braking guard
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 could result in a colli
sion.
- Switch adaptive cruise control off tempo
rar ily when driv ing in turning lanes, on
expressway exits or in construc tion
zones. This prevents the vehicle from ac
celerating to the set speed when in these
situations.
- Th e adaptive cruise 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 adaptive cr uise 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 vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
ano ther vehicle too closely . Always re
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch adaptive cruise control off when it
is not being used.
QJ Note
The sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and underbody.
That could affect the adaptive
cruise control system and braking guard. Have yo ur authorized Aud i dea ler or a u
thorized Audi Service Facility check their
function.
In curves
Applies to vehicles: with Audi adaptive cruise contro l
Fig. 115 Examp le: driv ing into a curve
When driving into a curve ¢fig . 115 and out
of a curve, the adaptive cruise control may re
act to a vehicle in the next lane and app ly the
brakes. You can override or prevent the brak
ing by pressing the accelerator pedal briefly.
' Stationary objects
Applies to vehicles: with Aud i adapt ive cru ise contro l
Fig. 116 Example: object changing lanes and station

T he adaptive cru ise control system only reacts
to objects that are moving or that the system
has a lready detected as moving. For examp le,
if a vehi cle@ , which has al ready been detect
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
® is located in front of that vehicle, the sys
tem will not react to the stat ionary veh icle.

What can adaptive cruise control do?
The adaptive cruise control works in conjunc
tion with a radar sensor installed in the front
of the vehicle
¢ page 107, fig. 114, which is
subject to designated system limits
¢page 109. Stationary objects are disregard
ed .
On open roads w ith no traffic, adaptive cruise
control works like a regular cruise control sys
tem. The stored speed is maintained. When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au
tomatically slows down to match that vehi
cle's speed and then maintains the distance
that the driver previously 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 control on,
you can set the current speed as the "control speed"
¢ page 109, Switching on and off.
When driving, you can stop cruise control
¢ page 111 or change the speed ¢ page 11 0
at any time .
You can a lso set the distance to the object
ahead and set the adaptive cruise control driv ing program

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 124 Instrument cluste r: approac h 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 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
gua rd 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 wi ll
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 this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light
I and indicator in the display will warn
you about the danger
c:> fig. 124. You will al
so hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter-
ll Th is is not ava ilable in som e coun tri es.
vene by braking and the message Braking
guard: Activated
will appear.
- If a coll ision is imminent , the sys tem wi ll
first 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 limits 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 complete deceleration shortly before a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision 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/
MMI* i::!> page 114, 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 driver is
always respons ible for braking at the cor
r ect time .
- Always pay close attention 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 examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traff ic).
