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 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
maneuvers¢
page 87.
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. 88 Front of the vehicle: sensors and video came ra
The areas that contain the radar and ultrason ­
ic sensors and the v ideo camera ¢
fig. 88
must neve r be covered by stickers or other ob­
jects or obstructed with dirt, insects, snow or
ice that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to¢
page 201. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some conditions:
- Objects can on ly be detected when they are
w ith in sensor range
¢page 83, fig. 91 .
-The system has a limited ability to detect
objects that are a shor t distance ahead,
off
t o the side of your vehicle or moving into
your lane.
- Some kinds of ve hicles 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 82 .
- Stationary objects¢ page 82.
& WARNING
Always pay attent ion to traffic when adap ­
tive cruise control is switched on and brak­ ing g uard is active. As the driver, you are
still respons ible for starting and for ma in­
taining speed and distance to other ob­
jects . Braking guard is used to assist you .
The driver must always take action to avo id
a collision. The driver is always responsible
for braking at the co rrect time.
- Improper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and conven ience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in full control of your ve­
hicle at all times,
- Always remember that the adaptive
cruise control and braking guard have
limits -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 .
I f registered by the radar sensors,

82 Audi ad apti ve cruise contr ol a nd bra king gu ard
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the v ideo camera, an acute col­
lis ion warn ing .
- For safety reasons, do not use adaptive
cruise co ntrol when driving 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) . Using the system under
these cond it ions cou ld result in a co lli ­
sion .
- Swi tch adap tive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerat ing to the set speed when in these
situations.
- The adapt ive cruise control system wi ll
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 traff ic, adaptive cruise
co ntrol will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
imals, objects c rossing the road or on­
coming objects .
- The function of the radar senso rs can be
affected by reflective objects such as
guard rai ls , the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise contro l canno t slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot br ing 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 sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard.
Have your authorized Aud i dea ler or au ­
thorized Audi Service Facility check their
funct ion .

Fig. 89 Ex ampl e: dri ving in to a curve
When d riving into a curve c> fig. 89 and out of
a curve, the ad aptive cruise control may react
to a vehicle in the next lane and apply the
brakes. You can override or prevent the brak­
i ng by pressing the acce lerator pedal briefly .

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
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 sud­
denly or if your own vehicle is t raveling 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. in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply. The indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 98. You
will also hear an acoustic signa l.
"' rl
"' 11
This is not ava ilable in som e coun tri es. rl
If you do not react fast enough or do not react
at all to the situation, braking guard will inter­
vene by braking.
- If a col lision is imminent, the system will
first provide an
acute warning by brief ly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
co llision.
- The system can initiate maximum braking
shortly before a collision
1 ) . Full deceleration
at high speeds occurs only in vehicles with
adaptive cru ise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the brak ing force .
- The pre sense functions also engage when a
collision is imm inent
c::> page 184 .
Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
c::> page 88, Settings in the 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 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 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 example when approaching a

88 Audi adaptive cruise control and braking guard
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- 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 all.
- Reflective surfaces including crash barri­
ers or tunnel entrances may impair the
function of the radar sensor.
({) Tips
-You can cancel the braking with increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeably or by swerving.
- Braking guard error messages
¢page 88.
- Keep in mind that braking guard can
brake unexpectedly . Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury.

(D Tips
- Your settings are automatically stored
and assigned to the remote control key being used at the time the settings are
made.
- If you restrict or switch off the ESC, the
braking guard also switches itself off
¢page 189.
- Switch braking guard off when you are
loading the vehicle onto a vehicle carrier,
train, ship or other type of transporta­
tion. This can prevent undesired warn­
ings from the braking guard system.
Messages
