After releasing the brake pedal, the brake
power is held for a
brief moment to prevent
the vehicle from rolling back when starting. At
this time, you can easily begin to move your
vehicle.
A WARNING
- If you did not begin moving immediately
after releasing the brake pedal, under
certain circumstances, the vehicle would
begin to roll backward. Depress the
brake pedal immediately or engage the
parking brake.
- Should the engine stall, depress the
brake pedal immediately or engage the
parking brake.
- In order to prevent the vehicle from roll ing back unintentionally when starting in
stop-and -go traffic, keep the brake pedal
depressed for a few seconds before driv

_&. WARNING
-
Following other vehicles too closely in
creases the risk of a crash and serious per
sonal injury .
- Following other vehicles too closely, par
ticu larly at higher speeds increases the
risk of coll is ions and serious personal in
jury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic .
- Always select a speed and distance to
traffic ahead that is safe and appropriate
under the prevailing traff ic, road, weath
er and lighting conditions.
- Never rely on the distance control fea
ture of ACC a lone to prevent rear-end col
lis ions. Always be prepared to b rake and
take evasive act io n to avoid co llisions
and other ac cident situations.
- Never allow the clos ing speed between
yo u a nd other vehicles to be so h igh that
the adaptive cruise control may not be
able to slow your vehicle safe ly . If clos

The Audi braking guard is active from a speed
of approx. 20 mph (30 km/h) and works with
in the system limits
¢ page 125 even when
the adaptive cruise contro l is deact ivated.
A radar senso r is bui lt into the front of the ve
hicle
¢ page 114, fig. 127. The system is in
tended to measure the distance to reflect ive
surfaces. If a measurement is not possible,
the system does not respond .
When the measurement has been taken, the
system can recognize a poss ibly hazardous sit
uation, for example, when a vehicle up ahead
in your lane of travel suddenly brakes or when
your ow n ve hicle is moving at high speed to
wards a much s lowe r vehicle up ahead . As
soon as the system senses that a possible co l
l ision with the vehicle up ahead can only be
avoided by immediate full brake appl ication or
by an avoidance maneuver, a warning appears .
The system has a defau lt response time to be
ab le to sig na l befo re a col lision occu rs. This
system response time is a utomat ica lly re
d uced if you acce lerate actively, for example
to join a highway. Braking, transverse acce ler
ation and the steering ang le can lead to a re
duced system response time. The warning is
deactivated if you begin to overtake with full
acceleration.
The system can make yo u aware of two differ
ent hazardo us situations:
Distance
The distance warn ing is g iven if the sys tem
calc ulates that the re is not enough d istance
to the vehicle up ahead a period of more than 5 seconds. If the distance is less than 30 feet
(9 meters) at SO mph (80 km/h), for example,
an optical d isplay comes on in the instrument
cluster
c> fig . 146.
If the vehicle ahead brakes sharply, A udi brak
ing guard cannot help you to avoid a co llision,
even in the case of an immediate response.
Take immediate act ion to avoid the collision
and increase the distance to the vehicle up
ahead .
Adapti ve crui se control 127
Speed
If there is a much slowe r vehicle mov ing up
ahead in your lane, or if the vehicle ahead brakes sharply, the Audi brak ing guard calcu
lates the point from which a collision can only
be avoided by f ull braking or by an avo idance
maneuver . If a warning does sound, a possible
collision with the veh icle in front can only be
avo ided through an evas ive maneuver or by
braking.
The warning is given in two stages:
- Pre-warnin g: A visua l display appears in the
instrument cluster and a warning tone
sounds.
- Acute w arning : If you do not respond to the
pre-warning, the second stage warning is
given. A quick brake application helps to di
rect your attention to the road and traffic
situat ion.
Under heavy braking, the brake assistant
i=> page 114 also helps you benefit from maxi
mum brak ing eff ic iency.
_& WARNING
Inattention can cause collisions, other ac
cidents and ser ious personal inju ries.
- Always pay close attent ion to the traffic,
even when the Audi braking guard is
sw itched on. The Audi braking guard pro
vides a wa rning but does not brake the
car for you. You must app ly the brakes
yourse lf!
- Always keep the safe and lega l distance
between yo ur vehicle and vehicles up
ahead.
- Aud i brak ing g uard wor ks within lim its
and will no t respond outside the system
limits, fo r example when approach ing a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the Audi braking guard works within
defined detect ion and range limits that
may prevent the proper detection of oth
er vehicles .
