The text message ... (three whi te dots) appears if a setting cannot be
implemented with the operating lever . The following are possib le
reasons :
• If you pull the control lever towards you to resume speed but no
requested speed was set .
• If you push the lever up to increase (or down to reduce) speed
when no speed has been set previously .
• I f you push the lever up to increase (or down to reduce) speed
and this speed is outside the range from 20 to 95 mph (Canada
models : 30 to 150 km/h) .
ACC functi onal it y limited
The text message ACC fun ctio na lit y lim ited appears when the ACC
system does not detect any objects over an extended time period.
For the time being, the distance to vehicles up ahead is not being
Controls and equip ­
ment
controlled . The ACC system is not switched off, so increased alert­
ness is required. The following may be reasons for the text message
ACC Functiona lly limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
react ing correctly, to veh ic les traveling ahead.
• I t is possible that you are driving on a road with very light traffic
without anything at the side of the road (e.g. guard rai ls, traffic
signs, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message disappears .
The ACC sensor is located in the right front trim grille::::>
page 118,
fig. 122 . If there is a loss of operation due to heavy contamination,
this area should cleaned to restore proper operation .
ACC not available
The text message ACC not available appears , for example, if the
temperature of the brakes is excessive. Adaptive cruise control is
temporarily not availab le . A warning tone sounds as a reminder .
ACC not a vailable !
The text message ACC not ava ila ble! appears in the event of a
malfunction . Adaptive cru ise control is turned off . A warning tone
sounds as a reminder. Have the system inspected by a qua lified
dea lership .
ACC sensor blo cked !
The text message ACC s ensor blocked ! appears when the ACC
system can no longer guarantee safe detection of objects. Adaptive
cruise control is turned off . A warning tone sounds as a reminder.
To decide whether it is necessary to switch off the ACC (ACC sensor
b locked
!) or if it is only a temporary condition (ACC F unctionally
limited), the system wi ll a lso takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC senso r is dirty or b locked (e .g . leaves, snow).
The sensor should be cleaned to restore proper sensor function

Engin e spee d !
The text message Engine sp ee d ! appears in vehicles with manual
transmission when the driver did not shift up or down in time while
using adaptive cruise contro l braking or accelerating, causing the
vehicle to exceed or not reach the perm itted limit speed. This
causes adaptive cruis e control to deactivate automatically . A chime
sounds as a reminder .
Parking brake !
The text message Parking brake! appears if emergency braking was
manually initiated with the Electromechanica l Parking Brake (EPBl.
The adaptive cruise contro l is turned off . This is accompanied by a
warning tone.
ESP a ctiv ati on
The text message ES P activati on appears if the E lectronic Stabil iza ­
tion Program (ESP ) has intervened . In this case the adapt ive cruise
control is automatical ly turned off . This is accompanied by a
warn ing tone.
Sp eed
The set speed in mph (Canada km/h ) a lways appears when saving or
changing the speed in adaptive cruise control~
page 121, "How is
the speed stored?" and~
page 121, "Changing stored speed".
Speed too low
The text message Speed too low appears if the cur ren t speed is too
low
to set or to hold the requested speed.
When setting a desired speed , it must be at leas t 20 mph (30 km/h).
At speeds below 12 mph (20 km/h), the cruise control is turned off.
In speeds over 95 mph (150 km/h), the system remains active and
resumes the speed of 95 mph (150 km /h) if the driver removes the
foot from the acce lerator .

• T he text DISTANCE! appears in the status line.
• The indicator light in the Instrument cluster blinks red.
• A warning tone sounds.
[ i] Tip s
• I f the adaptive cruise control initiates braking, the hydraulic
brake system is under pressure. Therefore, the brake peda l distance
is shorter and the pedal "feels" harder.
• Adaptive cruise control is switched off after pressing the foot­
brake . The speed saved up this point can be resumed.
• To resume the saved speed, release the brake pedal and press
the control lever~
page 122, "Turning adaptive cruise control off
temporarily".
• I f you use the accelerator t o go faster than the speed of the
object ahead of you, the
dri ver inter vention prompt will not be
accompanied by a wa rning signal.
• I f the speed you previously set is exceeded, the indicator light in
the speed ometer will switch off .•

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cruise con tro l is g overned by physical
and system -specified limits . Also, under certain circumstances, the
ACC system may react unexpectedly or late from the driver's point
of view. Therefore, always be attentive and intervene, if necessary:
• when driv ing around curves =>
page 130
• when vehicles in front are not in line with your vehicle
=>
page 131
• when other vehic les are changing lanes=> page 131
• when o ther vehicles a re di fficu lt to detec t=> pag e 131.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray . Th is can result in vehicles driv ing ahead being in adequate ly
detected or, in some circumstances, not detected at all. If ne ces ­
sary , take a ction yourself! •

Audi braking guard
Applies to vehicl es: wi th a dapt ive c ruise co ntrol
Description
Audi braking guard warns you of a threatening collision
with a vehicle ahead .
Fig. 142 Display in the
instrument cluster
The Audi braking guard is active from a speed of approx. 20 mph
(30 km /h) and works within the system limits~
page 130even when
the adaptive cruise control is deactivated .
A radar sensor is built into the front of the vehicle~
page 118,
fig. 122. The system is intended to measure the distance to reflec­
tive surfaces. If a measurement is not possible, the system does not
respond.
When the measurement has taken place, the system can assess a hazardous situation, when a vehicle ahead suddenly brakes or when
your own vehicle is driving at high speed towards a much slower
vehicle ahead. As soon as the system assumes that a possible colli ­
sion with the vehicle ahead can only be avo ided by immediate all­
out braking or by an avoiding maneuver, a warning appears.
The system has a pre-set response time to be able to warn in good
time. This system response time is automatically reduced if you acce lerate actively, for example to join a highway. Braking, trans ­
verse acceleration and the steering angle can lead to a reduced
system response time. The warning is deactivated if you begin to
overtake with full acceleration .
The system draws your attention to two different hazardous situa ­
tions:
Distance
The distance warning is issued in the event of inadequate distance
to the vehicle ahead a period of more than 5 seconds . If the distance
is less than 30 feet (9 meters) at 50 mph (80 km/h), for example, an
optical display is faded in on the instrument cluster~ fig. 142.
If the vehicle ahead brakes sharply, a collision cannot be avoided,
even in the case of an immediate response. In this case , increase the
distance to the vehicle ahead.
Speed
If there is a much slower vehicle ahead in your lane, or if the vehicle
ahead brakes sharply, the Audi braking guard calculates the point
from which a collision can only be avoided by all -out braking or by
~

an avoidin g maneuver. If a warni ng does sound, a possibl e col lis ion
w ith th e vehicle in fro nt can b e avo id ed thr ough a n evas ive
maneuve r or by brakin g.
T he warning is given in two stages:
• Pre-warning: A n op tica l disp lay a pp ea rs in th e in str umen t clus te r
and a warn ing tone sounds.
• Acute warning : If you do not respon d to t he pr e-war nin g, the

& WARNING
Always pay attention to traffic , even when the Audi braking guard
is switched on . You are always responsible for your speed and the
distance between your vehicle and other vehicles .
• Always keep the legally stipulated safety distance between
your vehicle and the vehicle ahead -danger of accident!
• The Audi brak ing guard does not respond outside the system
limits , for example if you approach a stationary obstacle (end of a
traff ic jam or breakdown vehicle ).
• Please observe that the Audi braking guard is subject to restric ­
tions in narrow bends due to the field of vision of the radar sensor.
This may possibly lead to obstacles not being detected.
• The radar sensor's
vision can be reduced by rain , snow and
heavy spray. This can result in vehicles driving ahead being inade ­
quately detected or , in some circumstances , not detected at all .
Always watch where you are driving.
• Reflecting objects such as e .g . crash barriers or the entrance to
a tunnel may impair the function of the radar sensor . •
