Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to: vehicles with Audi adaptive cruise contro l
Fig. 132 Instrument cluste r: approach warning
Braking guard uses a radar sensor. It also func-
tions within the limits of the system when adap-
tive 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 collision. 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 sharply .
When this warning is given, it may only be pos-
sible to avoid a collision by swerving or brak ing
sharp ly. The indicator light . will warn you
about the danger
¢fig. 132. You will also hear
an acoustic signal.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
by braking and the message
Braking guard: Acti-
vated
will appear.

> This is not ava ilable in some countries.
- If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
apply ing the brakes.
- If you do not react to the acute warning, brak-
ing guard can brake within the limits of the sys-
tem. This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a comp lete decelerat ion shortly be-
fore a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision is immi-
nent, it can increase the braking force .
Which functions can be controlled?
You can switch braking guard and the distance/
approach warn ing on or
off in the radio/MM!*

A WARNING
-
Lack of attention can cause collisions, other
accidents and serious personal injur ies. 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 t ime.
- Always pay close attention to traffic, even
when the braking guard is switched 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 wit hin limits and will
not respond outside the system limits, for
examp le 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 braking guard works only within defined
detection and range limits that may prevent
the proper detect ion of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
