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 regulating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system .
If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac ­
celerate your vehicle. This helps to make driv­
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 88.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them
properly at all times.

c:::> fig. 82
must never be cove red by stic kers or other ob­
jects or obstructed with dirt, insects, snow or
ice that will interfere w ith the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to
r:;, page 211. The same applies
for any modifications made in
the front area.
T he function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ithin sensor range
c:::> fig . 85.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of veh icles are hard to detect;
for examp le 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 al l.

& WARNING
A lways pay attention to traffic when adap­
tive cruise contro l is switched on and brak­
ing guard is active. As the driver, you are
still respons ible for starting and for main­
taining speed and distance to other ob­
jects. Braking guard is used to assist you .
The dr iver must always take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking at the correct time.
- Improper use of adaptive cru ise control
can cause collisions, other acc idents and
serious personal injury.
- Never let the comfort and convenience
that adaptive cruise control and braking
gua rd offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
hicle at a ll times,
- Always remember that the adaptive
cr uise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled o r disabled vehicle.
I f re gistered by the radar sensors,

Audi adapt ive crui se c ontrol an d bra kin g guard 8 3
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the video camera, an acute col­ lis ion warn ing.
- For safety reasons, do not use adaptive
cruise control when driving 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). Using the system under
these cond itions cou ld result in a co lli ­
sion .
- Switch adaptive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones . This prevents the vehicle from ac­
celerating to the set speed when in these
situations .
- The adapt ive cru ise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­ ride the speed and distance regulation .
- When approaching stationary objects such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people , an­
ima ls, objects crossing the road o r on­
coming objects .
- The function of the radar sensors can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
heavy rain or i ce.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
conditions .
- To prevent unintended operation, always
switch ACC off when it is not being used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and underbody. That cou ld affect the adaptive
cruise control system and brak ing guard .
Have your authorized Aud i dea ler or a u­
thorized Audi Serv ice Facility check their
funct ion.

F ig . 92 Instr ument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the lim its of
the system when adapt ive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approachi ng a veh icle up
ahead that is moving more slowly . Bra king
g ua rd does not react if it cannot detect th e
situ ation .
The system advises you of various situations:
- The
distan ce 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 coll is io n. The indicator
li ght
I in the display comes on .
- The
approach warning is g iven when a de­
tected veh icle up ahead in yo ur lane is mov ­
i ng much more slowly than you are o r if it
brakes sha rply . W hen this wa rning is given,
it m ay only be poss ible to avoid a collision

A WARNING
-
Lack of attentio n can cause collisions, oth-
er accidents and serio us pe rsonal injuries.
Th e braking gua rd is an ass ist system and
ca nnot prevent a collision by it self. T he
dr ive r m ust always intervene. The dr ive r is
a lways res ponsib le f or br ak ing at the cor­
r e ct t ime.
- Always p ay clo se a ttent ion to traff ic,
even when the braking guar d is swi tched
o n. Be ready to in tervene and be ready to
take comp lete contro l whenever necessa­
ry. Always keep the safe and legal dis ­
tance between your ve hicle and veh icles
up ahead.
- Braking guard works within limits and
w ill not respond outside t he system lim­
its, for examp le w hen approachi ng a
stopped vehicle or stati onary obstacle ..,.

- Alw ays remember that the radar sensor
for the b raking guard works only within
defined detection and ra nge limits that
may prev ent the proper det ection of oth­
er ve hicles.
- The ra dar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent rances may impair the
function of the radar sensor.

A UD I
Fi g. 100 Rear of t he ve hicle: positio n of t he se nsors
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicl es th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The fas ter a vehicle ap­
p roaches, the sooner the display in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en­
t er your "blind spot", at the latest.
Aud i side assist 95
@ Veh icles left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph or
15 km/h), the display in the exterio r mir ror
turns on as soon as the vehicle enters your blind spot.
T he disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the veh icle and your
vehicle is greater than 9 mph or 15 km/h).
Functi onal limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the d isp lay in the exterior mirror may
turn on even though there is no veh icle locat­
ed in the area that is cr itical for a lane change.
For example:
- if the lanes are narrow or if your are dr iving
on the edge of your lane.
If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to you r
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lan e ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors with stickers,
deposits, bicycle wheels or other objects, be­
cause this will affect the function . Do not use
s ide ass ist when towing a trailer . For informa­
tion on clean ing, refer to
q page 211.
_&. WARNING
-Always pay a ttent ion to traffic and to t he
ar ea a round your ve hicl e. S ide assist can­
not repla ce a driver's attention. The driv­
er a lone is always responsible fo r lane
changes and similar driving mane uvers.

96 Audi side assist
-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der 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 au­
thorized Audi Service Facility check their
function.
