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).

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! •

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. •

Audi lane assist -
----------------
, Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warning. This can be due to the
following:
• There are no boundary lines, or there is only one boundary line
present .
• The boundary lines are not detected (e.g. due to snow, dirt, wet
conditions or light shining into the camera lens).
• More than two boundary lines (such as at construction sites) are
located in the vehicle's lane.
• The vehicle's speed is below the speed needed to activate it,
which is about
40 mph (65 km/h).
• The lane is narrower than about
8 ft. (2.5 ml, or wider than about
16 ft. (5 ml.
• The curve is too sharp.
Notes on the instrument cluster display
When the lane assist turns off automatically, the instrument cluster
indicator goes out and one of the following messages appears on
the display:
Audi lane assist not available: Currently no sensor vision
This message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• The exterior side of the camera viewing window=>
page 150,
fig. 148 is covered with dirt or ice. Clean this part of the windshield.
• The camera viewing window is fogged up on the inside. In this
case, wait until the fog disappears before turning lane assist on
again.
• The system was unable to detect boundary lines over an
extended period of time due to road conditions (such as snow­
covered lanes). Do not turn lane assist on again until the lines can
be more easily detected.
Audi lane assist not available
Controls and equip ­
ment A temporary malfunction is preventing
lane assist from operating .
Try turning on lane assist again at a later time.
Audi lane assist: system fault
The system should be checked by an authorized Audi dealer or other qualified workshop.
[ i] Tips
• Make sure that the camera viewing window=> page 150, fig. 148
is not covered by stickers or similar objects .
• Always keep the camera viewing window clean. This can usually
be done by operating the windshield wipers. •

Setting the warning time
Early: This setting warns the driver before a wheel touches the
detected lane boundary line. The warning depends on the vehicle's
angle as it approaches the boundary line . If you approach a
boundary line gradually, the warning w ill occur earlier. If you
approach the boundary line at a very sharp ang le, the warning will
occur just before a wheel touches the line.
Adaptive : In this setting, the warning time adjusts to the character ­
istics of the road and the vehic le speed. The warning occurs later for
curves and occurs earlier for straight stretches of road . The warning
occurs later on narrow roads than on wide roads.
Late: This setting warns the driver when a whee l drives over the
detected lane boundary line .
Setting the steering wheel vibration
When adjusting the steering wheel vibration, the steering wheel
vibrates so that you can check the intensity you have set.
[ i ] Tips
• When making the adjustment, lane assist is not activated. The
steering wheel vibrates briefly only to assist you in changing the
setting .
• Your settings are automatically stored and assigned to the
remote control key being used.•
