Audi adaptive cruise
control and braking
guard
Introduction
App lies to: veh icles with Audi adaptive cruise contro l
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 de ­
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your veh i­
cle . This helps to make driving more comfortable
on long highway stretches .
The braking gua rd system can warn you about an
impend ing collision and initiat e braking maneu­
vers
¢ page 115.
Adaptive cruise control and braking guard have
technical lim itations that you must know, so
please read th is section carefully, understand
how the system works and use them properly at
all times.
General information
General information
Applies to: vehicles with Audi adaptive cruise control
Fig. 122 Fro nt o f th e ve hicle: Pos it ion of rada r sen sor
The area that contains the radar sensor
¢
fig . 122 must never be covered by st ickers or
other objects or obs tructed with dirt, insects,
snow or ice that w ill interfere w ith the adaptive
cruise control system and braking guard. For in­
formation on cleaning, refer to¢
page 204 . The
same applies for any modifications made in the
front area . T
he function of the adaptive cruise control sys ­
tem and braking guard is limited under some
condit ions:
- Ob jects can on ly be de tected when they are
within sensor range
q page 111, fig . 125.
-The sys tem has a limited ability to de tect ob­
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, ve hicles w ith hig h
ground clearance or overhanging loads may be
detected when it is too late or they may not b e
detected at all.
- When driving through curves
¢ page 110 .
- Stationa ry objects q page 110 .
,&_ WARNING
-= -Always pay attention to t raffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are still re­
sponsible for starting and for maintain ing
speed and distance to other objects . Braking
g uard is used to ass ist you . The driver must
a lways take act ion to avoid a co llision . The
driver is always respons ible for braking at the
cor rect time.
- I mproper use of adaptive cruise control can
cause collisions, other accidents and ser ious
pe rsonal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and braking g uard
offe r distract you from the need to be a lert
to traffic cond itions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adapt ive cruise
control and braking guard have limits -they
will not 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, such as vehicles stopped
in a traff ic jam, a stalled or disab led vehicle .
If reg istered by the radar sensor, vehicles or
obstacles that a re not mov ing can trigger a
coll is ion warning and if confi rmed by the
video camera, an acute co llision wa rning.

Audi adaptive cruise control and braking guard
-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 ra in and hydroplan­
ing). Using the system under these condi·
tions could result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations .
- The adaptive cruis e control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regu lation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani­
mals, objects crossing the road or oncom ing
objects.
- The function of the radar sensor can be af­
fected 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 adap·
t ive cruise control cannot slow or brake the
vehicle safely when you fo llow another veh i­
cle too closely. Always remember that the
automatic braking function cannot bring the
vehicle to a sudden or emergency stop un­
der these conditions .
- To prevent unintended operation, always
switch adaptive cruise control off when it is
not being used.
(D Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive
cruise control system and braking guard .
Have your authorized Audi dealer or author­
ized Audi Service Facility check their function.

In curves
App lies to : vehicles wit h Audi adapt ive cruise control
Fig. 123 Example: driv ing into a curve
When driving into a curve c:::> fig . 123 and out of a
curve, the adapt ive cruise control may react to a
vehicle in the next lane and apply the brakes . You
can override or prevent the braking by pressing
the accelerator pedal briefly.
Stationary objects
Applies to: vehicles wi th Audi adaptive cruise control
Fig . 124 Examp le: object chang ing lanes and stat ionary
ob ject
The adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving . Fo r example, if ave­
hicle @, which has already been detected by the
adaptive cruise control, turns or changes lanes
and another stationary vehicle @ is located in
front of that vehicle, the system will not react to
the sta tionary veh icle.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to: ve hicles with Audi adaptive cruise co ntro l
Fig. 132 Instrument cluste r: approach warning
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive 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 g iven 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 .
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
s ible to avo id a col lision by swerving or brak ing
sharp ly. Th e indicator light . will warn you
about the danger
¢fig. 132. 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
by braking and the message
Braking guard: Acti­
vated
will appear.
1> Th is is not ava ilab le in some coun tries.
-If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
apply ing the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys­
tem. This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a comp lete decelerat ion shortly be­
fore a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force .
Which functions can be controlled?
You can switch braking guard and the distance/
approach warn ing on or
off in the radio/MM!*
¢ page 116, Settings in the radio/MM!*.
A WARNING
-
Lack of attention can cause collisions, other
accidents and ser ious personal in juries. The
braking guard is an assist system and cannot
prevent a collision by itself. The driver must
always intervene. The driver is always respon­
sible for braking at the correct tim e.
- 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 necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead .
- Braking guard works wit hin limits and will
not respond outside the system limits, for
examp le when approaching a stopped veh i­
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 guard works only within defined
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

at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function

(D Tips
-You can cancel the braking that is initiated
by the system by braking yourself, by accel­
erating noticeably or by swerving.

- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . This in­
creases the risk of an acc ident. The brakes
must be d ried fi rst w ith a few careful b rake
applications.
