Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 99 Instrument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adapt ive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud-
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving 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 de-
tected vehicle up ahead in your lane is mov-
ing much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply . The indicator
light. and indicator in the display will
warn you about the danger

This is not avail able in some count ries.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter·
vene by braking.
- If a coll ision 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,
braking guard can brake wit h increasing
force with in the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
short ly before a collision
1
l . Full deceleration
at high speeds occurs only in vehicles with
adapt ive cruise control and side assist (pre
sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is im·
m inent, it can increase the brak ing force.
- The pre sense functions also engage when a
collision is imminent

A
WARNING
Lack of attention can cause collisions, oth-
er accidents and serious personal injuries .
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The dr iver is
always responsible for braking at the cor-
rect time.
- Always pay close att ent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take comp lete control whenever necessa-
ry. Always keep the safe and legal dis-
tance between your vehicle and vehicles
up ahead.
- Braking guard works within limits and
will not respond outside the system lim·
its, for example when approaching a ..,.
