In stop-and-go traffic, adaptive cruise control can
brake until the vehicle is stationary and then be-
gin driving again under certain conditions
¢ page 92.
Audi braking guard can warn you about an im-
pending collision and initiate braking maneuvers
¢pa ge 94.
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢
page 91, Switching on/off.
When driving, you can stop cruise control
¢ page 92 or change the speed
¢
page 92 at
anytime.
You can also set the distance to the object mov-
ing ahead and set the driving mode of the adap-
tive cruise control ¢ page 93 .
General information
Applies to: veh icles with Audi adaptive cruise control
Fig. 91
Front of the vehicle: sen so rs and video came ra
The areas that contain the radar and ultrasonic
sensors and the video camera ¢ fig. 91 must not
be covered by stickers, deposits or other objects
because they can int erfe re with the function of
the adaptive cruise control system and braking
guard. For information on cleaning, refer to
¢ page 235. The same applies for any modifica-
tions made in the front area.
The function of the adaptive cruise control sys-
tem and brak ing guard is limited under some
conditions.
- Objects can only be detected when they are
within the sensor range ¢ page 88, fig. 90 .
Assist
- The system has a limited ability to detect ob-
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane.
- Objects t hat are difficult to detect such as mo-
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves ¢ page 90.
- With stationary objects ¢ page 90 .
A
WARNING
~
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re-
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision . The
driver is always responsible for braking at the
correct time.
- For safety reasons, do not use adaptive
cruise control when driving 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 condi-
tions increases the risk of an accident.
- Switch adaptive cruise control off tempora-
rily when driving in turning lanes, on ex-
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations.
- 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 objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani-
mals, objects crossing the road 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.
