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

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.

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. ..,

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

Fig. 116 Rear of the vehicle: pos it ion of the sensors
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
cr itical for a lane change even if it is still some­
what far away. The faster a veh icle approaches ,
the sooner the display in the exterior mirror w il l
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
98
are indicated by the time they enter your "blind
spot", at the latest .
© Vehicles left behind
If you slow ly pass a vehicle that side assist has
de tected (the diffe rence in speed between the
vehicle 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 wi ll 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 crit ica l 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 driv ing 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 ass ist
functions are limited.
Do not cover the radar sensors
c:> fig. 116 with
stickers, deposits, bicycle wheels or other ob­
j ects, because th is w ill affect the function . Do not
use side assist when towing a trailer. For infor­
mation on cleaning, refer to
c:> page 182.
A WARNING
- Always pay attention to traff ic 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 . IJ>-

-Improper reliance on the side assist system
can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, snow or heavy mist.
- on very wide lanes, in tight curves or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system. Have
your authorized Audi dealer or authorized
Audi Service Facility check their function.
(D Tips
-If the window glass in the driver's door or
front passenger's door has been tinted , the
display in the exterior mirror may be misin­
terpreted.
