The system a llows only speeds to be set be ­
tween 20 to 95 mph (30 to 150 km/h) to be
set. This speed range is faint ly illuminated in
the speedometer (LED lights).
Ind icator lights (symbols )
-- Open road :
The indicator light_
shows that ACC is act ive and that no moving
vehicle has been detected with in range of the radar sensor up ahead in your lane of
travel. The set speed is maintained.
- - Driving in traff ic: The ind icator
light - shows that a vehicle moving in
your lane of travel has been detected up
front in your lane of travel. Your speed is ad­
justed according to the speed of the vehicle
up front . ACC accelerates and brakes auto­
matically within the sys tem's capabilit ies .
-- Driver int ervention prompt: The
red flashing warning light- means
Request for driver to a ssume control. You
as the dr iver must s low the vehicle with the
f oot brake. The symbo l-t ells you

_& WARNING
Improper use of the adaptive cruise con­
trol feat ures and inattent ion can lead to a
crash and ser ious pe rsonal inju ry.
- Never a llow the closing speed between
you and othe r vehicles to be so high that
the adaptive cruise cont ro l may not be
ab le to slow yo ur vehicle safely. If clos­
ing speed is too high, you must apply the
brakes yo urself to reduce t he ris k of a
rear-e nd crash.
- Always sele ct a greate r followi ng d is­
tance to the vehicle up ahead on wet
roads t han on d ry roads.

ACC: Unavailable
The text message ACC: Unavailable appears,
for example, if the temperature of the brakes
i s excessive. Adaptive cruise control is tempo­
rarily not available. A warning tone sounds as
a reminder .
ACC: Not available
The text message ACC: Not available appears
in the event of a malfuncti on. Adaptive cruise
control is turned
off . A warning tone sounds
as a reminder. Have the system inspected by a
q ua lified dealership.
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
the right of the front license plate . If the ACC
sensor is dirty or blocked, clean the area to re­
store system operat ion.

ACC functionality limited
T he message ACC functionality limited ap­
pears when the ACC System does not detect
any moving vehicles up ahead in yo ur lane of
trave l for a longer period of time. During this
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.
T he ACC sensor is located be hind the area to
the right of the front license plate. If the ACC
senso r is dirty or blocked, clean the area to re­
store system operation.

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.

When driving around curves
Applies to vehicles: wit h adaptive cruise control
Fig. 142 Vehicle e nter ing a curve
Fi g. 14 3 Vehicle leav ing a curve
Entering a curv e
When entering a curve, the adaptive cruise
control may react to a vehicle in the next lane
and apply the brakes in your vehicle
¢ fig . 142. The braking action can be overrid·
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
ce lerator pedal.

Vehicles offset to one side
Applies to vehicles: with adaptive cruise control
Fig. 144 Vehicle traveling a head o utside the detect ion
range of t he rada r se nsor
Vehicles mov ing up ahead but offset i n the
lan e cannot be detected by ACC until they are
in sensor range.
Lane changes by other vehicles
Applies to vehicles: with adaptive cruise control
Fig. 145 A vehicle changes lanes
Vehicles that cut into your lane a sho rt dis­
tance in front of you cannot be detected by
ACC until they are in senso r range.
Vehicles that are difficult to detect
Applies to vehicles: with adaptive cruis e contro l
Fig. 146 Two -wheeled vehicle drivi ng ahead
Some vehicles moving up ahead in your lane
of trave l are difficult to detect, for examp le
two -wheeled veh icles, vehicles w ith high
ground clearance, loads sticking out the back .
Vehicles like this are often detected late or in
some situations not at all.
Stationary vehicles
Applies to vehicles: with adaptive cruise contro l
Fig. 147 Turning and stationary ve hicle
Fig. 148 Sheering out and stat ionary veh icle
If a vehicle that has been detected by ACC ex­
its the highway or sheers out into the neigh­
boring travel lane, and there is a stationary
vehicle ahead of that vehicle, ACC will not de·
tect or react to that stationary vehicle

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 .
