Instrument cluster : approac h 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 Audi 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 coll ision by swerving or braking
sharply. The indicator light .
will warn you
about t he danger¢ fig. 102. 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 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 within the limits of the sys-
tem. This reduces the vehicle speed in the event
of a collis ion.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration 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 warning on or off in the radio or MMI

A
WARNING
Lack of attent ion 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 switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al-
ways keep the safe and legal distance be-
tween your vehicle and vehicles up ahead.
- Braking guard works with in limits and will
not respond outside the system limits, for
examp le when approach ing 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 detection 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
