G:;/ !f Safety systems
The fl (USA models) ;EI (Canada models) in
dicator light monitors the safety systems (e.g .

Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
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 helps 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
c:::> page 92.
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.

Applies to vehicles: with Audi adaptive cruise control
Fig. 87 Front of th e veh icle: senso rs and video camera
The areas that conta in the radar and ultrason
ic sensors and the v ideo camera
c:::> fig. 87
must neve r be cove red by stic kers or other ob
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor
mation on cleaning, refer to
c:::> page 213. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::> page 88, fig. 90.
- 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 ve hicles 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 all.
-When driving through curves

& WARNING
A lways pay attention to traffic when adap
tive cruise contro l is switched on and brak
ing g uard is active. As the dr iver, 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 a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve
h icle 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 o r disabled vehicle.
