If Adaptive Cruise Control is turned off or no speed is set, no vehicle
is shown.
@ Status
• The text OFF appears in white letters when Adaptive Cruise
Control is turned off.
• The text
AVAILABLE appears in white letters when the system is
turned on but no requested speed has been set.
• The text
OVERRIDE appears in white letters when you exceed the
requested speed by accelerating.
• The text
DISTANCE! appears in red letters when the interval to a
vehic le traveling ahead is too short and you also have to slow your
vehicle with the foot brake.
• The text messages
DISTANCE 1, DISTANCE 2, DISTANCE 3 or
DISTANCE 4
appear in green letters to indicate the time interval
(distance) you have set and ACC is active.
© Distance
A pointer (arrow) is shown in this area. When slowly approaching a
moving vehicle detected ahead in your lane of travel, this pointer
represents the distance to that vehicle . When approaching that
vehicle rapidly, it serves as early warning of an impending request
for the driver to assume ful l vehicle control. The pointer moves on a
scale from right to left.
Open road: With an open road and no moving vehicle detected up
ahead, no pointer is shown.
Driving in traffic: If a vehicle traveling up ahead in your lane of travel
is detected, the pointer moves to the center area of the scale. This
area represents the time interval (distance) set. It is shown in
green
to make it easier to see.
Driver intervention prompt: Whenever the selected time interval
(distance) to the vehicle moving up ahead in your lane of travel is
less than the time interval (distance) set, the pointer moves into the
red area of the display. When the pointer reaches the farthest posi­
tion on the left, the driver intervention prompt is disp layed to indi -cate that the driver must now assume full vehicle control in order to
prevent
a collision. •

System limitations
Applies to vehicles : with Ada ptive C rui se C ont rol
General information
The radar sensor has limits that the driver must know to
be able to use ACC properly.
The Adaptive Cruise Control works within limits 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 view. There­
fore, always be attentive to what is happening around you and
always be ready to intervene, if necessary:
• when driving around curves=>
page 151.
• when vehicles up front are not in line with your vehicle
=>
page 151.
• when other vehicles are changing lanes=> page 151.
• when other vehicles are difficult to detect=> page 152.
• when vehicles up ahead are not moving or obstacles are in your
travel lane=>
page 152.
& WARNING
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 detected at all.
• Always pay careful attention to the traffic situation and be
ready to intervene and be ready to take complete control when­
ever necessary. •

Audi lane ass is t -
-------------------------
Audi lane assist
Lane assist
Applies to veh icles : with lane assist
Description
Lane a ssist helps you keep y our 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
detects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indica tor light /: on the instrument cluster .
I f the system is in active standby mode and the turn signal is acti­
vated before driving ov er the boundary line, the warning does not
occur since the sys tem allows for intenti onal lane changes.
The system is designed for driving on freeways and expanded high ­
ways and t hus works on ly at speeds of 40 mph (65 km/h) or mo re .
& WARNING
• Lane ass ist will not k eep your vehicle in your lane. The sy stem
only warns the d riv er w hen t he vehicle i s le av ing the lan e. The
driv er is alway s re spon sible for keeping the vehicle in the lane.
• The camera is not able to d ete ct all lane boundary lines and in
s o me cases might al so dete ct lane str ucture s or objects as
boundary lines . This c an le ad to in corre ct wa rning s or warnings
that fa il to go off at all .
• The camer a's visibili ty ca n be i mpaired by vehi cle s ahe ad of
you , for instan ce, or by rain , snow , h eavy spray or li ght shining into
th e cam era lens . Thi s can ca use lane as sis t to f ail to d ete ct

• .___A_ u_ d _ i_l_a _n _ e_ a_ s_s _is _ t _________________________________________________ _
I Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warn ing. This can be due to the
following:
• There are no boundary lines, or there is on ly 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 s ide of the camera viewing window=>
page 153,
fig. 171 is covered with dirt or ice. Clean this part of the windshield.
• The camera v iewing 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
A temporary malfunction is preventing lane assist from operating .
Try turning on lane assist again a t 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 153, fig. 171
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. •

Earl y:
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 l ine gradua lly, the warning will occur ear lier. If you
approach the boundary line at a very sharp angle, the warning wi ll
occur just before a whee l touches the line.
Adapti ve : In this setting, the warning time adjusts to the character ­
istics of the road and the vehicle 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.
Se ttin g th e 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 whee l vibrates briefly only to assist you in changing the
setting .
• Your settings are automatically stored and assigned to the
remote contro l key being used. •

T he system works at speeds faster than 19 mph (30 km/h) .
& WARNING
• Improper reliance on the side assist system can cause colli­
sions and seriou s per sonal injury:
- Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to c hange lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly.
• The 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 veh icles or , in some cases, not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Please note that side assi st indicates there are approaching
vehicles, or vehicles in your bl ind spot , only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km /h).
• S ide assist signal does not work around tight corners (turning
radiu s less than 328 feet or 100 m ).
• Side assist is no replacement for the driver's full attention . The
d river alone is responsible for lane changes and similar driv ing
maneuvers. Always keep an eye on the d ire ction you are travel ing
and the relevant area around the vehicle .
