Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise contro 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

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 108, fig . 119.
-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 ¢
page 107.
- Stationary objects i::!) page 107.
& 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 action to avoid a collision . The
driver is always responsible fo r braking at the
correct 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 dist ract you from the need to be alert
to traffic cond itions 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 disab led 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: with Audi adaptive cruise contro l
Fig. 126 In strument cluste r: appro ach 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 braking guard do?
When detected in time, the system can assess
situations when a veh icle ahead brakes suddenly
or if your own vehicle i s 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 variou s 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 indic ator 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 ib le to avo id a collision by swerving or braking
sharply. The indicator light . and indicator in
the display will warn you about the danger
¢fig. 126. 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: Acti
vated
will appear.
l) Thi s is no t a vail able in som e coun trie s.
112
- If a collision is imminent, the system will first
provid e an
acute warning by briefly and sharply
app ly ing the b rakes.
- 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 comp lete deceleration shortly be
fore a collision ll.
- If the braking gua rd 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/MM
I*
¢ page 113 , 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

! OJ CD
In certain cases, a vehicle will be classified as
cr itical for a la ne change even if it is still some
what far away. The faster a veh icle approaches ,
the soo ner the d isplay in the exterior mirror w il l
turn on.
@ Vehicles tra veling with you
Veh icles traveling with you are ind icated in the
exterior m irror if they are classified as critical for
a lane change. All ve hicl es detected by side assist
116
are indicated by the time they enter your "blind
spot", at th e latest .
@ Vehicle s left behind
If you slow ly pass a vehicle that s ide assist has
de tected (the diffe rence in speed between the
vehicle and your vehicle is less than 9 mph or
15 km/h), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot.
The display w ill not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ
ence in speed between the vehicle and your vehi
cle is greater than 9 mph or 15 km/h).
Functional limitation s
The radar sensors are designed to detect the lef t
and rig ht adjacent lanes whe n the road lanes are
the normal width . In certa in situations, the dis
play in the exterior mirror may turn on even
t hough there is no vehicle located in the area
that is crit ica l for a lane change. For example :
- if the lanes a re narrow o r if your are driving on
the edge of your lane . If this is the case, the
system may have detect ed the vehicle in anoth
e r lane that is
not adjacent to your current lane.
- if yo u are driving through a curve. Side assist
may r eact to a vehicle that is on e lane over
from the ad jacent lane.
- if side assist reacts to other objects (such as
high or disp laced guard rai ls) .
- In poor weather condit ions. The side assist
functions are limited .
Do no t cover the radar sensors ¢
fig. 130 wit h
stickers, deposits, bicycl e wheels or other ob
jects, because this wi ll affect the function. Do not
u se side assist when towing a trailer . For infor
mation on cleaning, refer to ¢
page 207.
A WARNING
-Always pay attention to traffic and to the
area around your veh icle . S ide assist cannot
replace a driver's attention . The driver alone
is always responsib le for lane changes and
sim ila r driv ing mane uve rs .

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.
