sta tus indi cator
The different symbols for the time intervals appear if you change the
settings ~ fig. 139 .
The text message ... (three white dots) appears if a setting cannot be implemented with the operating lever . The following are possible
reasons:
• If you pul l the control lever towards you to resume speed but no
requested speed was set .
• I f you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.
• If 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 fun cti ona lity limited
The text message AC C functionalit y limited 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
Con tro ls and eq uip­
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
reacting correctly, to veh ic les travel ing 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 area under the front license plate.
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 n ot ava ila ble appears, for example, if the
t emperature of the brakes is excessive. Adap tive Cruise Control is
temporarily not available . A warning tone sounds as a reminder .
ACC not available!
The text message ACC not ava ilable ! appears in the event of a
malfunction . Adaptive Cruise Contro l is tur ned o ff. A warning to ne
sounds as a reminder. Have the system inspected by a qua lified
dea lership .
ACC se nsor bl ocked !
The text message AC C sensor blocked ! appears when the ACC
System can no longer guarantee safe detection of objects . Adaptive
cruise control is turned off. A chime sounds as a rem inder .
To decide whether it is necessary to switch off the ACC (ACC sensor
blocked
!) or if it is only a temporary condition (ACC functionality
limited), the system wi ll also takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC sensor is dirty o r blocked (e .g . leaves, sn ow).

v ention prompt
In cer tain situati ons, the braking power of t he Adaptive cruise
control is not sufficient to maintain an adequate distance from the
object ahead. In this situation, the Adap tive cruise contro l ca lls on
you as the driver to take action.
The
driver intervent ion prompt a lerts you visual ly and audibly.
• A red vehicle is shown in the instrument c luster disp lay
=> fig. 1 40 .
• The tex t

• The indicator light
,;:::::,11 .. ,;:::::, in the speedometer b links red.
• An warning tone sounds .
[ i ] Tips
• I f the Adaptive cruise control initiates braking, the hydraul ic
brake system is under pressure. Therefore, the brake peda l distance
is shorter and the pedal "feels" harder.
• Adaptive Cruise C ontro l is switched off af ter pressing the foot -
brake. The speed
saved up this point can be resumed. _,,,

_____________________________________________ A_ d_a ...: pc.. t _i_ v _e_ C_ ru_ is_ e_ C_ o_n_ t_ r_ o _ l __ ,n
• To resume the saved speed, release the brake pedal and press
t he control lever~
page 139, "Turning Adaptive Cruise Contro l off
temporarily".
• If you use the accelerator to go faster than the speed of the
object ahead of you, the
drive r int erv enti on prompt will not be
accompanied by a warning signal.
• If the speed you previously set is exceeded, the indicator light in
t he speedometer wi ll switch off .•

General information
Some driving situations which affect the function of the
radar sensor ore described below.
When driving, the Adaptive Cru ise Control is governed by physical
and system -specified limits. Also, under certain circumstances, the
ACC system may react unexpec tedly or late from the dr iver's point
of view. Therefore, always be attentive and intervene, if necessary :
• when driv ing around curves~
page 148
• when vehicles in front are not in line with your
vehic le ~
page 148
• when other vehicles are changing lanes~ page 149
• when other vehic les are difficu lt to detect~ page 149.

& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray. This can result in vehicles driving ahead being inadequately
detected or, in some circumstances, not detected at all. If neces­
sary, take action yourself! •

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 overridden by depressing the
accelerator pedal.
Leaving a curve
At the exit from very long curves the predictive lane reading can
cause th e Adaptive Cruise Control to react to another vehicle in the
next lane and apply the brakes in your vehicle => fig. 143. The
braking action can be over ridden by depressing the accelerator
pedal. •

Audi lane assist
Lane assist
Applies to vehic les : w ith lane assist
Description
Lane assist helps you keep your vehicle in your lane.
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver . If lane assist
de tects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indicator light /: on the instrument cluster.
If the system is in active standby mode and the turn signal is acti­
vated before driving over the boundary line, the warning does not
occur since the system allows for intentional lane changes.
The system is designed for driving on freeways and expanded high­
ways and thus works only at speeds of 40 mph (65 km/h) or more.
& WARNING
• Lane assist will not keep your vehicle in your lane. The system
only warns the driver when the vehicle is leaving the lane . The
driver is always responsible for keeping the vehicle in the lane .
• The camera is not able to detect all lane boundary lines and in
some cases might also detect lane structures or objects as
boundary lines . This can lead to incorrect warnings or warnings
that fail to go off at all.
• The camera's visibility can be impaired by vehicles ahead of
you , for instance, or by rain, snow, heavy spray or light shining into
the camera lens. This can cause lane assist to fail to detect
boundary lines. •
