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.

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.
