Audi adaptive cruise
control
Description
Applies to: vehicles with Audi adaptive cruise control
)
F ig . 122 De tect ion range
A ss istance systems
T he adaptive cruise cont rol system is a combina­
tion of speed and distance regu lation.
It assists
the driver by both regu lating the speed and
maintain ing a d istance to the vehicle driv ing
ahead, w ith in the limits of the system. If the sys­
tem detects a vehicle driving ahead, the adaptive cruise control can brake and accelerate your vehi­
cle . T his increases d riving comfort during long
trips o n highways and in stop-and-go traffic.
What can adap tiv e crui se con trol do ?
The adaptive cru ise control sys tem uses radar .
The radar is subject to designated system limits
¢ page 124 .
On open roads with no traffic, it functions like a
cruise contro l system . The stored speed is main­
ta ined . When approaching a vehicle ahead and
the system detects it, the adapt ive cruise control
system automat ically brakes to match that ob­
ject's speed and t hen maintains the stored d is­
t a nce. As soon as t he sys tem does not de tec t a
vehicle driving ahead, adaptive cruise cont ro l ac ­
ce lerates up to the stored speed .
Within the lim its of t he sys tem, adapt ive cru ise
contro l can brake in stop -and-go t raff ic until t he
vehicle is s tat iona ry and then begin driving again
under certain conditions ¢
page 12 7, Driving in
stop-ond-go traffic .
Which functions can be controlled?
When you switc h adap tive cr uise control o n, you
can set the cur rent speed as the "contro l speed"
¢ page 12 5, Switching on/off .
When driving, yo u can stop cru ise cont rol
¢ page 127 or change the speed ¢page 126 at
any t ime .
You can also set the distance to the vehicle ahead and set the adaptive c ruise cont rol d riving pro­

General information
Applies to: vehicles with Audi adaptive cruise contro l/Audi pre
sense front
Fig . 1 23 Front o f veh icle: sensor
The rada r sensor area r:!) fig. 123 must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap ­
tive cruise control or the pre sense front . For in­
formation on cleaning,
see ¢ page 354 . The
same applies for any modifications made in the
front area .
The funct ion of the adaptive cruise contro l sys­
tem or pre sense front is limited in some condi ­
tions:
-Vehicles can only be detected when they are
within the sensor range
¢page 123, fig. 122 .
-The system has a lim ited abi lity to detect
vehicles that are a short d istance ahead , off to
the side of your vehicle or moving into your lane .
-Objects that are difficu lt to detect such as mo­
torcycles, vehicles with h igh ground clearance
or an overhang ing load are detected late or not
detected at all.
-When dr iving through curves ¢ page 125.
-When the vehicle is stationary ¢ page 125.
A WARNING
Always pay attent io n to the traffic aro und you
when adaptive cruise control is switched on .
As the driver, you a re st ill respons ible for your
own speed and the distance to othe r vehicles.
Th e adapt ive cr uise control is u sed to assis t
you . The driver must a lways take act ion to
avoid a collision . The driver is always responsi ­
ble for brak ing at the correct time .
124
-For safety reasons, do not use adaptive
cru ise control when dr iving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing). Using the system under these cond i­
tions could result in a co llision .
-Switch adaptive cruise cont rol off tempora­
rily when dr iv ing in turning lanes, on ex­
pressway ex its or in construction zones. This
prevents the veh icle from accelerating to
the stored speed when in these situat io ns.
-The adap tive cruise contro l system will not
brake by itself if you put yo ur foot on the ac­
celerator pedal. Doing so c an override the
speed and distance regulation .
- Adapt ive cruise control does not respond to
peop le, animals, or crossing or oncoming
objects .
-The funct ion of the radar se nsors can be af­
fected by ref lective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice .
~ Note
The sensor can be d isplaced by impacts or
damage to the bumper, wheel housing and underbody . This can impair the adaptive
cruise control. Have an authorized A udi dealer
or authorized Audi Service Facility check their
f u nct ion.

When approaching a veh icle driving ahead, the
adaptive cru ise control system brakes to match
that vehicle's speed and then adjusts to the set
d istance.
If the vehicle dr iv ing ahead accelerates ,
then the adaptive cruise control will also acceler­
ate up to the speed that you have set.
The higher the speed, the greate r the d istance
