The distance at which the adaptive cruise con

time intervals. A time interval to a vehicle in
front is estab lished and maintained. Th is pro

A WARNING
Following ot her vehicles too closely in
creases the risk of a crash and serious per
sonal injury .
- Following other vehicles too closely, par
t icularly at higher speeds increases the
risk of collis ions and serious pe rsonal in
Jury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to br ing you r vehicle to a safe
stop and makes i t even mo re ne cessary
to pay close attention to traffic.
- Always select a speed and distance to
traffic ahead that is safe and appropr iate
under the prevailing traff ic, road, weath
er and Lighting conditions .
- Never re ly on the dis tance control fea
ture of ACC a lone to p reven t rear -end col
lisions. Always be prepared to brake and
take evasive act ion to avoid co llisions
and other acc ident situations.
- Never allow the closing speed between
you and other vehicles to be so h igh that
the adaptive cruise control may not be
able to slow your vehicle safe ly. If clos
ing speed is too high, you must apply the
brakes yourself to reduce the risk of a
rear-end c rash.

Audi braking guard
Description
Applies to vehicles: with a daptive cruise co ntrol
Audi braking guard warns you of a possible
collision with a moving vehicle up ahead .
Fig. 149 Display in the instrument cluster
The Audi braking guard is act ive from a speed
of app rox. 20 mph (30 km/h) and wor ks w ith
in the system limits¢
page 127 even when
the adaptive cruise contro l is deactivated .
A radar sensor is bu ilt into the front of the ve
h icle
¢page 116, fig. 130. 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 meas urement has been taken, the
system can recognize a possibly hazardous sit
uation, for example, whe n a vehicle up ahead
in your lane of trave l sudden ly brakes or when
your own vehicle is moving at high speed to wards a much slower vehicle up ahead . As
soon as the system senses that a possible col
lision with the vehicle up ahead can only be
avoided by immed iate full brake app lication or
by an avoidance maneuver, a warning appea rs.
The system has a defau lt response time to be
able to signal before a collision occurs. This
system response time is automat ica lly re
duced if you acce lerate actively, fo r example
to join a highway . B rak ing, tra nsverse acceler
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 .
Adapti ve crui se control 129
The system can make you aware o f two diffe r
ent hazardous situations:
Distance
T he distance warning is given if the system
ca lculates that there is not enough distance
to the vehicle up 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 examp le,
an optical display comes on in the instrument
cluster¢
fig. 149.
If the vehicle ahead brakes sharp ly, Audi brak
ing guard cannot help you to avoid a collision,
even in the case of an immediate response.
Take immed iate action to avoid the co llision
and increase the distance to the vehicle up
ahead.
Speed
If there is a much slower vehicle moving up
ahead in your lane, or if the vehicle ahead
brakes sharply, the Aud i brak ing guard calcu
lates the po int from which a collision can only
be avoided by full braking or by an avoidance
maneuve r. If a warning does sou nd, a poss ible
collision with the ve hicle in front can on ly be
avo ided th rough an evas ive maneuve r or by
braking.
T he warning is given in two stages :
-Pre -warning: A visual display appears in the
instrument cluster and a warning tone
sounds.
- Acute warning : If you do not respond to the
pre-warn ing, 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 ass istant
¢
page 116 also helps you benef it from maxi
mum brak ing eff ic iency.
A WARNING
I nattention can cause collisions, other ac
cidents and ser ious perso nal i nju ries.
130 Adapti ve crui se co ntrol
- Always pay close attention to the traffic,
even when the Audi brak ing guard is
switched on. The Aud i brak ing guard pro
vides a warning but does not brake the
car for you . You must apply the brakes
yourself!
- Always keep the safe and legal distance
between your vehicle and veh icles up
ahead.
-Audi braking guard works within limits and w ill not respond outs ide the system
limits, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the A udi braking guard works within
defined detection and range limits that
may prevent the proper detection of oth
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de
tected at all.
- Always pay careful attention to the traf
fic s ituation and be ready to intervene
and be ready to take complete control
whenever necessary.
- Reflective surfaces includ ing crash barri
ers or tunnel entrances may impair the
function of the radar sensor .

· General information '
App lies to vehicles : wit h side assist
Side assist has limits and cannot detect
vehicles under all road and weather condi
tions . Please remember system limitations
and never rely on the system, especially when:
- driving through curves¢
page 136,
-lanes are of different widths¢ page 137.
' When driving through curves
Applies to vehicles: wit h side assist
Side assist cannot detect vehicles in curves
with a turning radius of less than 328 feet
(100 m).
When driving through a curve, it is possible
that side assist may register a vehicle two
lanes over, and the signal on the outside mir
ror will light up.
