The dist ance warn ing is issued in the event of
inadequate distance to the vehicle ahead a pe-
riod of more than S seconds. If the distance is
less than 30 feet (9 meters) at SO mph
(80 km/h), for example, an optical display is
faded in on the instrument cluster ¢ fig. 130.
If the vehicle ahead brakes sharply, a collision
cannot be avoided, even in the case of an im-
mediate response . In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower vehicle ahead in your
lane, or if the vehicle ahead brakes sharply,
the Audi braking guard calculates the point
from which a collision can only be avoided by
all-out braking or by an avoiding maneuver. If
a warni ng does sound, a possible collision
with the vehicle in front can be avoided
through an evasive maneuver or by braking .
The warning is given in two stages :
- Pre-warning:
An optical disp lay appears in
the instr ument cluster and a warning tone
sounds.
- Acute warni ng:
If you do not respond to the
pre-warning, the second stage, the acute
warning, is issued. A brake jolt reminds you
to concentrate on the road again.
Under heavy breaking, brake ass ist

WARNING
Always pay attention to traffic, even when
the Audi braking guard is switched on. You
are always responsible for your speed and
the distance between your vehicle and oth-
er vehicles.
- Always keep the legally stipulated safety
distance between your vehicle and the
vehicle ahead - danger of accident!
- The Audi braking guard does not respond
outside the system limits, for example if
you approach a st at ionary obst acle (end
of a t raffic jam or breakdown vehicle).

- Please observe that the Audi braking
guard is subject to restrict ions in narrow
bends due to the field of vision of the ra-
dar sensor. This may possibly lead to ob-
stacles not being detected .
- The radar sensor's vision can be reduced
by rain, snow and heavy spray. This can
result in vehicles driving ahead be ing in-
adequately detected or, in some circum-
stances, not detected at all. Always
watch where you are driving.
- Reflecting objects such as e.g. crash bar-
riers or t he ent ran ce to a tunne l may im-
pair the function of t he radar sensor .
