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 regu lating vehi cle 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 vehi­
cle. This helps to make driving more comfortable
on long highway stretches.
The braking guard system can warn you about an impend ing collision and initiate braking maneu ­
vers
¢ page 113.
Adaptive cruise control and braking guard have
technical limitations that you must know, so
p lease read this section carefu lly, understand
how the system works and use them properly at
all times.

Fig. 116 Fro nt of the vehicle : Position of rada r sensor
The area that contains the radar sensor
¢ fig. 116 must never be covered by stickers or
other objects or obs tructed with dirt, insects,
snow or ice that w ill interfere with the adaptive
cru ise control system and braking guard. For in­
formation on cleaning, refer to ¢
page 208. The
same applies for any modifications made in the
front area. T
he function of the adaptive cruise contro l 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
¢ page 109, fig. 119.
-The system has a limi ted ability to de tect ob­
jects that are a short d istance 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, 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

-Stationa ry objects ¢ page 108.
,&_ WARNING
-= -Always pay attention to traffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are sti ll re ­
sponsible for start ing and for maintaining
speed and distance to other objects. Braking
g uard is used to assist you . The drive r must
a lways take action to avo id a collision . Th e
d river is always responsible for bra kin g at the
correct t ime.
- I mproper use of adaptive cru ise control can
cau se collisions, o ther accidents and serious
pe rsonal injury.
- Neve r let the comfort and conve nience that
adap tive cr uise control and braking guard
o ff er distrac t you from the need to be alert
t o traffic con ditions and the need to remain
i n full control of your vehicle at all times,
- Always remember that the adaptive 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 sta lled or d isabled vehicle.
If registered by the radar sensor, vehicles or
obstacles that a re not moving can t rigger a
coll is io n warning and if confi rmed by the
video came ra, a n acute collision warning.

Audi adapt ive cru ise control and brak ing gu ard
- 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 hydrop lan­
ing). Using the system under these condi­
t ions could resu lt in a col lision.
- Switch adaptive cruise control off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situat ions.
- The adapt ive cr uise control sys tem wi ll not
brake by itself if yo u put you r foot on the ac­
celerator pedal. Doing so can ove rride the
speed and distance regulation.
- When approach ing stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking g uard will have
limited function.
- The adapt ive cr uise control system and brak­
ing guard do not react to people, animals,
objects cross ing the road or oncoming ob­
jects .
- 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 veh icle so closely that you
cannot stop your vehicle safe ly . The adap­
t ive cru ise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
automa tic brak ing funct ion c annot bring the
vehicle to a sud den or emergency stop un­
der these conditions.
- To prevent unin tended operation, always
switch adaptive c ruise control off when it is
not be ing used .
(D Note
The sensor can be displaced by impa cts or
damage to the bumper, wheel housing and
underbody . That could affect the adaptive
cruise contro l system and braking gua rd . Have
your authorized A udi dealer or authorized
Audi Service Facility check their function .

In curves
Applies to vehicles: with Audi adapt ive cruise contro l
Fig. 117 Example: dri ving in to a c urve
When dr iving into a curve c:::> fig. 117 and out of a
curve, the adaptive 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 peda l briefly .
Stationary objects
Applies to vehicles: wi th Audi adaptive cruise control
Fig . 118 Example: objec t cha ngin g la n es and sta tionary
ob jec t
The adaptive cruise contro l system only reacts to
ob jects that are moving or that the system has
already detected as moving. For example, if ave­
hicle @, which has already been de tec ted by the
adap tive cruise con trol, turns or changes lanes
and another stationary veh icle @ is located in
front of that ve hicle, the system will not react to
the stat ionary vehicle.

What can adaptive cruise control do?
The adaptive cruise control works in conjunction
with a radar sensor installed in the front of the
vehi cle
¢ page 107, fig. 116, which is subject to
designated system limits¢
page 109 . Stationary
objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control wo rks like a reg ular cruise control system.
The stored speed is maintained . When approach­
ing a moving vehicle detected up ahead, the
adapt ive cruise control system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­
ously stored. As soon as the system does not de­
tect 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 "contro l speed"
¢ page 109, Switching on and off.
When driving , you can stop cruise control
¢
page 111 or change the speed ¢ page 110 at
any time.
You can also set the distance to the object ahead
and set the adaptive cruise control driving pro­
gram

Audi adapt ive crui se cont rol and bra king gu ard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 126 Instrument cluste r: app roac h warn ing
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 bra king gu ard do ?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own veh icle 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 s ituation.
The system advises you of various situations:
- The
di sta nce wa rning 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 d isplay comes o n.
- The
app roach warning is g iven 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 avoid a co llision by swerving or braki ng
sharp ly. The indicator light . and indicator in
t h e d isplay w ill warn yo u about the danger
¢ fig. 126. You wi ll also hear an acoust ic signa l.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene by bra king and the message
Br aking guard : A cti-
~ vat ed will appear. co ~ co
rl I.O
"' N "' 11
This is not ava ilable in som e count ries. rl
- If a collision is imminent, the system wi ll first
provide an
a cute war ning by brief ly and sharply
app ly 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 veh icle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a comp lete deceleration shortly be­
fore a collisionl).
- 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 function s can b e cont roll ed ?
You can switch braking guard and the distance/
approach warning on or off in the radio/MMI*
¢ page 114, Settings in the radio/MM!*.
A WARNING
-
Lack of attention can cause collisions, other
accidents and serious personal injuries. The b raking guard is an ass ist system and cannot
p revent a coll is ion by itself. The dr iver must
a lways intervene. The driver is always respon­
s ib le for b ra ki ng at the corre ct time.
- Always pay close attent ion to traffic, even
when the b rak ing guard is switched on. Be
ready to intervene and be ready to take com ­
p lete control whenever necessary . Always
keep the safe a nd legal distance between
your vehicle and vehicles up ahead.
- Braking guard works within limits and will not respond outside the system limits, for
examp le when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­ f ic).
- Always remember that the radar sensor for
the braking guard works on ly w ithin defined
detection and range limits that may prevent
the prope r detection of other vehicles.
- The radar sensor's funct ion and range can
be reduced by ra in, snow and heavy spray.
Moving vehicles up ahead may not be
