Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance program is
a combined speed and distance control system.
Fig. 151 Front
bumper: Position of
radar sensor
Adaptive Cruise Control can help make driving more relaxed and
less tiring, particularly during long trips on interstates or other
highways that are generally straight .
Set ACC to maintain a constant, legal travel speed between 20 and
95 mph (30 -150 km/h) that is appropriate for prevailing traffic
conditions. Select a following distance to the vehicle ahead and ACC
will adjust your speed to maintain that distance .
Adaptive Cruise Contro l has technical limitations that you must
know, so please read this section carefully, understand how the
system works and use it proper ly at all times .
How does it work?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column =>
page 142, "How is the speed stored?" and
=>
page 144, "How is the distance set?" .
Contro ls and eq uip­
ment
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=> page 146, "Driver information" .
What is important for you to know
There are limits to what Adaptive Cruise Control can do as the
vehicle is being driven =>
page 150, "System limitations" .
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury.
• Always remember that the Adaptive Cruise Control has limits -
it will not slow the vehicle down or maintain the set distance
when you drive towards an obstacle or something on or near the
road that is not moving, such as vehicles stopped in a traffic jam,
a stalled or disabled vehicle.
• Always remember that the Adaptive Cruise Control cannot
detect a vehicle that is driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and
bicycles .
• Never drive at speeds that are too fast for traffic, road and
weather conditions .
• The Adaptive Cruise Control cannot slow or brake the vehicle
safely when you follow another vehicle too closely. Always
remember that the Adaptive Cruise Control has a braking power
that is only about 30% of the vehicle 's maximum braking ability.
Always be prepared to brake and take evasive action to avoid colli­
sions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to _,,,

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

• .___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. •

Sett ing th e war ning tim e
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. •
