Introduction
Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehi cle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system. If the system de-
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your vehi-
cle. This he lps to make driving more comfortable
both on long highway stretches and in stop-and-
go traffic.
The braking guard system can warn you about an
impending collision and initiate braking maneu-
vers¢ page
91.
Adaptive cruise control and braking guard have
technica l limitations that you m ust know, so
please read this section carefu lly, understand
how the system works and use them properly at
all times.

Fig. 89
Front of t he vehicle: sensors and video camera
The areas that contain the radar and ultrason ic
sensors and the video camera ¢ fig. 89 must nev-
e r be covered by stickers or other objects or ob-
structed with dirt, insects, snow or ice that will
interfere with the adaptive cruise contro l system
and braking guard . For information on cleaning,
refer to ¢ page 205 . The same applies for any
modif ications made in the front area.
The function of the adaptive cru ise contro l sys-
tem and braking guard is limited unde r some
conditions:
- Objects can only be de t ected when they are
with in sensor range ¢page 87, fig. 92.
- The system has a limited ability to detect ob-
jec t s that are a shor t d istance ahead, off to the
side of your vehicle or mov ing into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, vehicles with high
ground clear a nce or overhanging loads may be
detected when it is too late o r they may not be
detected at all.

WARNING
Always pay attent ion to traffic when adap t ive
cruise control is switched on and braking
guard is active. As the driver, you are sti ll re-
sponsib le for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you. The driver must
a lways take action to avoid a col lision . The
d river is always responsible for brak ing at the
correct t ime.
- Improper use of adaptive cruise control can
cause collisions, other accidents and serious
pe rsonal injury.
- Never let the comfort and conve nience that
adapt ive cruise control and braking guard
offer distrac t you from the need to be alert
to traffic condit io ns and t he need t o remain
in full control of your veh icle at all times,
- Always remember t hat the adaptive cruise
con t rol and bra king guard have limits - they
will not slow t he vehicle down or maintain
the set distance when you dr ive towards an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehicles
or obstacles that a re not moving can trigger
a collision wa rning and if confirmed by the
video came ra, an acute collision warning.
