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
