approach warn ing
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
situation
.
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 braking
sharply. The indicator light

r

the danger

.
You will also hear an acoustic signa
l.
If
you do not react fast enough or
do
not react at
all to the
situation,
Braking
guard will
int
ervene
by braking
and
the message
braking guard
inter-
vention
will appear.

- If a
colli
sion is imminent, the system wi ll
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
collision.
-
At speeds under 20 mph (30
km/h),
the system
can initiate a complete deceleration shortly be-
fore a collisionl
l_
-
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 coll ision by itself. The dr iver must
always
intervene.
The
driver is
always respon-
sib le for
braking at the correct time.
-
Always pay
close
attent ion
to
traffic,
even
when
the braking
guard
is
switched
on. Be
ready
to
intervene and
be ready to take com-
plete control whenever
necessary.
Always
keep the safe and legal distance between
your vehicle and vehicles
up
ahead.
- Braking
guard
works within 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 w ith in 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
