Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
A pp lies to: ve hicles w ith Aud i adapt ive cruise co ntro l
The adaptive cruise contro l system assists the
driver by regulating vehicle speed and helping to
maintain a set distance to the veh icle 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
impending collision and initiate braking maneu­
vers
c> page 94.
Adaptive cruise control and braking guard have
technical limitations that you must know, so
please read th is section carefully, understand
how the system works and use them properly at
all times.

Fig. 102 Front of t he veh icle: Posit ion of radar sensor
The area that contains the radar sensor
c> fig. 102 must never be covered by st ickers or
other objects or obstructed 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
c> page 182. The
same appl ies for any modifications made in the
front area .

The function of the adaptive cruise control sys ­
tem and braking guard is limited under some
condit ions:
- Objects can only be detected when they are
within sensor range
<:!) page 90, fig . 105.
-The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane.
- Some k inds of veh icles are hard to detect; for
example motorcycles, veh icles 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 89.
- Stationary objects i::!) page 89 .
& WARNING
-Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects . Braking
guard is used to assist you . The driver must
a lways take act ion to avoid a collision . The
driver is always responsible for braking at the
cor rect time.
- Improper use of adaptive cruise contro l can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adapt ive cr uise control and braking guard
offe r distract you from the need to be alert
to traffic conditions and the need to remain
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 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 disabled veh icle.
If registered by the radar sensor, veh icles o r
obstacles that are not moving can trigger a
coll ision warning and if confirmed by the
video camera, an acute collision warning. ..,

Audi ada pti ve c ruise contr ol and br akin g gu ard
-For safety reasons, do not use adapt ive
cruise contro l when driv ing 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) . Us ing the system under these condi­
t ions could result in a collision .
- Switch adaptive cruise contro l off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in const ruc tion zones. This
preven ts the vehicle from accelerating to
the set speed when in these situat ions .
- T he adapt ive cr uise con trol system will no t
br ake by i tself if you pu t your foot on the ac­
celerator peda l. Doing so can override the
speed and distance regulation.
- Whe n approaching stat ionary obje cts such
as stopped traffic, adapt ive cruise control
will not respo nd and braking guard will have
limited function .
- The adaptive cruise control system and
brak ing guard do not react to peop le, ani­
ma ls, objects crossing the road or oncom ing
objects.
- The function of the radar sensor can be af­
fected by reflective objects such as guard
rai ls, t he entrance to a tunnel, heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safely . The adap­
t ive cr uise control cannot slow or brake the
vehicle safely when you follow another veh i­
cle too close ly. Always remember th at the
au tom atic b raking function ca nnot br ing the
vehicle to a sudden or emergency stop un­
der these conditions .
- T o preven t unintended operation, always
switch AC C off when i t is not be ing used.
(D Note
The sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and
underbody. That co uld affect the adaptive
cru ise con trol sys tem and braking guard.

F ig. 103 Ex amp le : d ri ving int o a c urve
When driving into a curve¢ fig. 103 and out of a
curve, the adapt ive cruise control may react to a
vehicle in the next lane and apply the brakes . Yo u
can override or prevent the b raking by press ing
the accelerator pedal b riefly.
Stationary objects

The adaptive cruise control system only reacts to
objects 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 stat ionary vehicle @ is located in
front of that vehicle, the system will not react to
t h e stationary veh icle.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to: vehicles w ith Audi adaptive cruise co ntro l
Fig. 112 Instrument cluster : approac h 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 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 situat ion.
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 detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply.
When this warning is given, it may only be pos­
s ible to avoid a collision by swerving or braking
sharply. The indicator light . will warn yo u
about the danger¢
fig. 112. You will also hear
an acoustic signal.
If you do not react fast enough or do not react at
a ll to the situation, Braking guard will intervene
by braking and the message
braking guard inter­
vention
will appear.
l) This is not ava ilab le in some countries.
94
- If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
app lying 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 collis ion.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration 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 warning on or off in the radio or MMI
¢ page 95, Settings in the radio/MM!.
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious 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 respon­
sible for braking at the correct time .
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al­
ways keep the safe and legal distance be ­
tween your vehicle and vehicles up ahead .
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approach ing a stopped vehi­
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 detection 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

- 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
c reases the risk of an acc ident. The bra kes
must be d ried fi rst w ith a few careful b rake
applications.
(D Note
- If you wash t he vehicle in an automatic car
wash, yo u m ust fold the exte rior m irrors in
to reduce the risk of damage. Power fo ld ing
exter ior mir ro rs* m ust only be folded in and
out using t he power folding fu nction .
- To reduce the risk of paint damage, do not
wash the vehicle in d irect sunlig ht.
- To reduce the risk of damage, do not wash
th e power top wit h a press ure washe r.
Ca re and cleaning
- To re duce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or s imilar items .
- Matte finish painted veh icle components:
- To reduce the risk of damage to the sur-
face, do not use po lishing agents or hard
