ACC: Sensor blocked
The text message ACC: Sensor blocked ap­
pears when the ACC System can no longer ac­
curately detect vehicles moving up ahead in
your lane of travel. Adaptive cruise control is turned
off. A warning tone also sounds as a re­
minder.
To decide whether it is necessary to switch
off
the ACC (ACC : Sensor blocked) or if it is only a
temporary condition (ACC functionality limit­
ed) the system will take into cons ideration the
outside temperature and/or the windshield
operat ion.
The ACC sensor is dirty or blocked (e.g. leaves,
snow).
The ACC sensor is located behind the area to

time, the distance to moving vehicles in your
lane of travel up ahead is not being ma in­
ta ined . The ACC system is not switched off,
and increased attention to the traffic situation
is absolutely necessary. The following may be
reasons why the message

appears :
- The ACC sensor is d irty . The ACC system is
not react ing, or is not reacting correctly, to
moving vehicles up ahead in your lane of
t ravel.
- There may be very light traffic on and there
is nothing that marks the side of the road
(for examp le, guard ra ils, traffic signs,
trees). As soon as a moving vehicle up ahead
is detected again, ACC becomes active again
and the message disappears.

System limitations
General information
Applies to vehicles: with adaptive cruise co ntrol
The radar sensor has limits that the driver
must know to be able to use ACC properly .
The adaptive cruise control works within lim­ its that are also related to radar sensor range
and sight distance . In some situations ACC
may react unusually or late from the driver's
point of v iew. Therefore, always be attent ive
to what is happening around you and always
be ready to intervene, if necessary:
-when driving around curves ¢page 127
- when vehicles up front are not in line with
your vehicle ¢ page 128
- when other veh icles are changing lanes
i=> page 128
- when other vehicles are difficult to detect
i=> page 128
- when vehicles up ahead are not moving or obstacles are in your travel lane i=>page 128
A WARNING
The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles up ahead may not be
prompt ly detec ted or may not be detected
a t all.
- Always pay careful att ention to the traf­
fic s ituation and be ready to intervene
and be re ady to take comp lete cont rol
whenever necessary.

den by depressing the accelerator pedal.
L e aving a curv e
At the end of very long curves, ACC's predic­
tive lane reading can cause ACC to react to an­
other vehicle in the next lane and app ly the
brakes on your vehicle¢ fig . 143. The braking
action can be overr idden by depress ing the ac­

Audi braking guard
Description
Applies to vehicles: with a daptive cruise co ntrol
Audi braking guard warns you of a possible
collision with a moving vehicle up ahead .
Fig. 149 Display in the instrument cluster
The Audi braking guard is act ive from a speed
of app rox. 20 mph (30 km/h) and wor ks w ith­
in the system limits¢
page 127 even when
the adaptive cruise contro l is deactivated .
A radar sensor is bu ilt into the front of the ve ­
h icle
¢page 116, fig. 130. The system is in ­
tended to measure the distance to reflect ive
surfaces .
If a measurement is not possible,
the system does not respond.
When the meas urement has been taken, the
system can recognize a possibly hazardous sit ­
uation, for example, whe n a vehicle up ahead
in your lane of trave l sudden ly brakes or when
your own vehicle is moving at high speed to­ wards a much slower vehicle up ahead . As
soon as the system senses that a possible col­
lision with the vehicle up ahead can only be
avoided by immed iate full brake app lication or
by an avoidance maneuver, a warning appea rs.
The system has a defau lt response time to be
able to signal before a collision occurs. This
system response time is automat ica lly re­
duced if you acce lerate actively, fo r example
to join a highway . B rak ing, tra nsverse acceler­
ation and the steering ang le can lead to a re­
duced system response time. The warning is
deactivated if you begin to overtake with full
acceleration .
Adapti ve crui se control 129
The system can make you aware o f two diffe r­
ent hazardous situations:
Distance
T he distance warning is given if the system
ca lculates that there is not enough distance
to the vehicle up ahead a pe riod of more than
S seconds . If the distance is less than 30 feet
(9 meters) at SO mph (80 km/h), for examp le,
an optical display comes on in the instrument
cluster¢
fig. 149.
If the vehicle ahead brakes sharp ly, Audi brak ­
ing guard cannot help you to avoid a collision,
even in the case of an immediate response.
Take immed iate action to avoid the co llision
and increase the distance to the vehicle up
ahead.
Speed
If there is a much slower vehicle moving up
ahead in your lane, or if the vehicle ahead
brakes sharply, the Aud i brak ing guard calcu­
lates the po int from which a collision can only
be avoided by full braking or by an avoidance
maneuve r. If a warning does sou nd, a poss ible
collision with the ve hicle in front can on ly be
avo ided th rough an evas ive maneuve r or by
braking.
T he warning is given in two stages :
-Pre -warning: A visual display appears in the
instrument cluster and a warning tone
sounds.
- Acute warning : If you do not respond to the
pre-warn ing, the second stage warning is
given. A quick brake application helps to di­
rect your attention to the road and traffic
situat ion.
Under heavy braking, the brake ass istant
¢
page 116 also helps you benef it from maxi­
mum brak ing eff ic iency.
A WARNING
I nattention can cause collisions, other ac­
cidents and ser ious perso nal i nju ries.

130 Adapti ve crui se co ntrol
- Always pay close attention to the traffic,
even when the Audi brak ing guard is
switched on. The Aud i brak ing guard pro­
vides a warning but does not brake the
car for you . You must apply the brakes
yourself!
- Always keep the safe and legal distance
between your vehicle and veh icles up
ahead.
-Audi braking guard works within limits and w ill not respond outs ide the system
limits, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the A udi braking guard works within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar 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 all.
- Always pay careful attention to the traf­
fic s ituation and be ready to intervene
and be ready to take complete control
whenever necessary.
- Reflective surfaces includ ing crash barri­
ers or tunnel entrances may impair the
function of the radar sensor .

Safety tips
App lies to vehicles: wit h side ass ist
The s ide ass ist detect ion may be lim ited when
d riving around narrow street corners , on hilly
streets, and under poor weathe r cond itions.
It is poss ible that the radar sensors may also
detect other objects , such as high o r stag­
gered guardra ils .
Side assist does not measure actual lane
width . T he system assumes a fixed lane w idth .
Detection in the left and r ight lanes is based
on this assumed lane width . When driving on
na rrow roads or when driving to the left or
right of the center of a travel lane , it is possi ­
b le that vehicles wi ll be detected that are
not
in the lane next to the lane you are using.
A WARNING
- Improper reliance on the s ide ass ist sys­
tem can cause collisions and serious per­
sonal injury :
- Neve r rely only on side assist when
changing lanes .
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side ass ist cannot detect a ll vehicles un­
der all cond itions- danger of accident!
- Side ass ist cannot detect vehicles in time
to alert you when they approach from beh ind at very h igh speeds or drop back
very quick ly .
- T he radar sensor's
vision can be reduced
or entirely blocked by rain, snow, and
heavy spray. This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at a ll.
Always keep an eye on the direction you are traveling and the relevant area
around the vehicle .
- 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). -
Side assist signa l does not work around
tight corners (turning radius less than
328 feet, or 100 m).
- Side assist is no replacement for the driv­
er 's full attention. The driver alone is re­
sponsible for lane changes and sim ilar
driving maneuvers. Always keep an eye
on the d irect ion you are traveling and the
re levant area around the vehicle.
(D Note
To ensure that side assist is not adversely
affected, you should not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
with stickers or bi cycle racks).
(D Tips
If the pos itions of the radar sensors have
been changed as a result of a rear end-co l­
lision, for instance, have s ide assist
checked by an autho rized Aud i deale r for
safety reasons.
