Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lat ing vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system .
If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac-
celerate your vehicle. This he lps to make driv-
ing 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
maneuvers

Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un-
derstand how the system works and use them
properly at all times.

The areas that conta in the radar and ultrason-
ic sensors and the video camera c:::> fig. 83
must neve r be cove red by stic kers or other ob-
jects or obstructed with dirt, insects, snow or
ice that will interfere with the adaptive cruise
control system and braking guard. For infor-
mation on cleaning, refer to
c:::> page 210. The
same applies for any modifications made in
the front area.
The function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de t ected when they are
with in sensor range
c:::> page 86, fig. 86.
- The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of veh icles are hard to detect;
for examp le motorcycles, veh icles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at al l.
-When driving through curves

& WARNING
Always pay attention to traffic when adap -
tive cruise contro l is switched on and brak-
ing g uard is active. As the driver, you are
still respons ible for starting and for main-
taining speed and distance to other ob-
jects. Braking guard is used to assist you .
The dr iver must always take action to avo id
a collis ion . The driver is always respons ible
fo r braking at the correc t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal injury.
- Never let the comfort and convenience
that adaptive cruise control and braking
gua rd offer distract you from the need to
be alert to traffic condit ions and t he
need to rema in in fu ll control of your ve-
hicle at a ll times,
- Always remember that the adaptive
cruise control and braking guard have
limits - they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some-
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
