Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed "
c!;> page 98, Switching on/off.
When driving, you can stop cruise control
c!;> page 100 or change the speed ¢ page 99 at
any time .
You can also set the dist ance to the vehicle d riv
ing ahead and set the driving mode of the adap
tive cruise control¢

General information
Appl ies to: ve hicles with Audi adaptive cruise co ntro l
Fig. 90 Fro nt o f th e ve hicle : sensor s and video c amer a
The areas wi th the radar and ul trasonic senso rs
and the video camera¢
fig. 90 must not be cov
ered by stickers, deposits or any other objects ,
because this can interfere with the adaptive
cruise control function. For information on clean ing, refer to¢
page 337. The same applies for
any modifications made in the front area .
In some driving situations , the adaptive cruise
control function is restricted:
- Vehicle s can only be detected when they are
within the sensor detection zones
¢ page 96,
fig . 89 .
-The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle or moving into your lane .
Assist
-Objects that are difficult to detect such as mo
torcycles, v ehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.

- When the vehicle is stationary ¢ page 98.
A WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on .
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you . The driver must always take action to
avoid a collision . The driver is always responsi
ble for braking at the correct time .
- For safety reasons, do not use adaptive
cruise control when the road surface is in poor condition and/or in bad weather condi
tions (such as ice, fog, gravel, heavy rain and
hydroplaning). Using the system under
these conditions increases the risk of an ac cident.
- Switch adaptive cruise control off tempora rily when driving in turning lanes, on ex
pressway exits (except if predictive control
is switched on) or in construction zones.
This prevents the vehicle from accelerating
to the stored speed when in these situa
tions .
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary obstacles
such as stopped traffic, adaptive cruise con
trol will respond with limited function .
-Adaptive cruise control does not respond to
people, animals, or crossing or oncoming
objects.
- The function of the radar sensors can be af
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
