Audi adapt ive crui se cont rol and bra king gu ard
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 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 helps to make driving more comfortable
on long highway stretches.
The braking guard system can warn you about an impend ing collision and initiate braking maneu
vers
¢ page 113.
Adaptive cruise control and braking guard have
technical limitations that you must know, so
p lease read this section carefu lly, understand
how the system works and use them properly at
all times.

Fig. 116 Fro nt of the vehicle : Position of rada r sensor
The area that contains the radar sensor
¢ fig. 116 must never be covered by stickers or
other objects or obs tructed with dirt, insects,
snow or ice that w ill interfere with the adaptive
cru ise control system and braking guard. For in
formation on cleaning, refer to ¢
page 208. The
same applies for any modifications made in the
front area. T
he function of the adaptive cruise contro l sys
tem and braking guard is limited under some
condit ions:
- Ob jects can on ly be de tected when they are
within sensor range
¢ page 109, fig. 119.
-The system has a limi ted ability to de tect ob
jects that are a short d istance ahead, off to the
side of your vehicle or moving into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, vehicles 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
-= -Always pay attention to traffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are sti ll re
sponsible for start ing and for maintaining
speed and distance to other objects. Braking
g uard is used to assist you . The drive r must
a lways take action to avo id a collision . Th e
d river is always responsible for bra kin g at the
correct t ime.
- I mproper use of adaptive cru ise control can
cau se collisions, o ther accidents and serious
pe rsonal injury.
- Neve r let the comfort and conve nience that
adap tive cr uise control and braking guard
o ff er distrac t you from the need to be alert
t o traffic con ditions and the need to remain
i n full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the 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, such as vehicles stopped
in a traff ic jam , a sta lled or d isabled vehicle.
If registered by the radar sensor, vehicles or
obstacles that a re not moving can t rigger a
coll is io n warning and if confi rmed by the
video came ra, a n acute collision warning.
