Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to: vehicles with Audi adapt ive cruise contro l
Fig. 106 Instrument cluster : approac h warning
Braking guard uses radar sensors and a video
camera. It also functions within the limits of the
system when adaptive cruise control is switched
off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov-
ing more slowly. Braking guard does not react if
it cannot detect the situat ion.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If the
vehicle ahead brakes sharply, you will not be
able to avoid a coll ision. The indicator light .
in the display comes on.
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharp ly.
When this warning is given, it may only be pos-
sible to avoid a collision by swerving or braking
sharp ly. The indicator light. and indicator in
the display will warn you about the danger
qfig. 106 . You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to t he situation, braking guard will intervene
by braking and the message
braking guard inter-
vention
will appear.

- If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
applying the brakes.
- If you do not react to the acute warning, brak-
ing guard can brake with increasing force with-
in the lim its of the system. This reduces the ve-
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a collision

) .
Full deceleration at
high speeds occurs only in vehicles with adap-
tive cruise control and side assist (pre sense
plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is immi-
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent

Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 9 7, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . The driver must
always int ervene. The driver is always respon-
sible for braking at the correct time.
- Always pay close attention to traffic, even
when the braking guard is swit ched on. Be
ready to intervene and be ready to take
comp lete control whenever necessary. Al-
ways keep the safe and legal distance be-
tween your vehicle and vehicles up ahead.
- Braking guard works within li mits and will
not respond outside the system limits, for
example when approaching a stopped vehi-
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf-
fic).
- Always remember that the radar sensor for
-
the brak ing guard works only within def ined ..,.
