Audi adapt ive crui se cont rol and bra king gu ard
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 95.
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.
General information

A pp lies to vehicles: with Audi adaptive cruise co ntrol
Fig. 93 Fr ont of th e veh icle : Posit ion of radar sensor
The area that contains the radar sensor¢ fig. 93
must never be covered by stickers or other ob­
jects or obstructed with dirt, insects, snow or ice
that will inte rfe re with the adapt ive cr uise con­
trol system and brak ing guard. For information
on cleaning, refer to ¢
page 184. The same ap­
p lies for any mod ificat ions made in the front
area. T
he function of the adaptive cruise cont ro l sys­
tem and braking guard is limited under some
condit ions:
- Ob jects can on ly be de tected when they are
with in sensor range¢
page 91, fig. 96.
-The system 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, 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 90 .
-Stationa ry objects ¢ page 90.
,&_ WARNING
-= -Always pay attention to traffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are still re­
sponsib le for start ing and for maintai ning
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 col lision . The
d river is always responsible for bra kin g at the
cor re ct t ime.
- I mp roper use of adaptive cruise control can
cau se collisions, o ther accidents and serious
pe rsonal injury.
- Never let the comfort and conve nience that
adapt ive cr uise control and braking guard
offer distrac t you from the need to be alert
to traffic con dit ions 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 somethi ng 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, an acute collision war ning.

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 ACC off when it is not be ing use d.
(D Note
The sensor can be disp laced by impacts or
damage to the bum per, whee l hou sing and
unde rbody. That could affe ct the adap tive
cruise contro l system and braking guard . Have
your authorized A udi dealer or authorized
Audi Service Facility c heck their function.

In curves
App lies to vehicles: wi th Aud i adapt ive cru ise contro l
Fig. 94 Example: dr iving into a cu rve
When dr iving into a curve c:::> fig. 94 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 Aud i adap tive cr uise con tro l
Fig. 95 Example: object chang ing lanes and stationary ob ·

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 detected by the
adaptive cruise control, turns or changes lanes
and another stationary veh icle @ is located in
front of that veh icle, the system will not react to
the stat ionary vehicle.

Audi adaptive cruise control and braking guard
When the adaptive cruise control is turned on,
you must press the clutch to shift gears (as usu­
al). When sh ifting normally or when pressing the
clutch, the adaptive cruise control remains
turned on.
After you have engaged the gear, you do
not need
to press the gas pedal. The adaptive cruise con­
trol accelerates automatically if necessary .
If you press down on the clutch for too long or
shift/coup le im properly, the adaptive cruise con­
trol may turn off automat ica lly.
@ Tips
You cannot turn on the adaptive cruise control
during a shifting operation.
Audi adaptive cruise control
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 Detection range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunction
with a rada r sensor installed in the front of the
veh icle¢
page 89, fig. 93, which is subject to
des ignat ed system limits¢
page 91. Stationa ry
objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control wo rks like a regu lar cruise control system.
The stored speed is mainta ined. When approach­
ing a moving vehicle detected up ahead, the
adaptive 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
acce lerates back up to the stored speed.
Which functions can be controlled?
When you switch adapt ive cr uise control on, you
can set the current speed as the "control speed"
¢ page 91, Switching on and off.
When driving, yo u can stop cru ise contro l
¢page 93 or change the speed ¢page 92 at
any time.
You can also set the distance to the object ahead
and set the adaptive cruise control dr iv ing pro­
gram ¢

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 103 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 Audi 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 s ituation .
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 d isplay 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 avoid a co llision by swerving or braki ng
sharply. The indicator light . and indicator in
the display will warn yo u about the danger
c> fig. 103. 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 braking and the message
braking guard inter-
~ vention will appear.

This is not available in som e count ries. rl
- If a collision is imminent, the system wi ll first
provide an
acute warning by briefly 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 vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete 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 functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
c> page 96, 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
prevent a collis ion by itself. The driver must
always intervene. The driver is always respon­
sib le for b ra kin g at the correct 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 com­
p lete control whenever necessary. Always
keep t he 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 proper 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

- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
(D Tips
- You can cance l the braking that is initiated
by the system by braking yourself, by accel­
erating noticeably or by swerving.
- Braking g uard error messages ~

Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faster a vehicle approaches, the sooner the display in the exterior mirror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
Audi side assist
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles left behind
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the ve­
hicle and your vehicle is less than 9 mph (15 km/
h)), the display in the exterior mirror turns on as
soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In certain situations, the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area that is critical for a lane change. For example:
- if the lanes are narrow or if your are driving on
the edge of your lane. If this is the case, the
system may have detected the vehicle in anoth­
er lane that is
not adjacent to your current lane.
- if you are driving through a curve. Side assist
may react to a vehicle that is one lane over from
the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the rada r senso rs¢
fig. 107 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function. Do not
u se side assist when towing a trailer. For infor­
mation on cleaning, refer to¢
page 184.
A WARNING
-Always pay attention to traffic and to the
area around your vehicle . Side assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers.
