The indicator light _
shows that ACC is active and that no moving
vehicle has been detected with in range of the radar sensor up ahead in your lane of
travel. The set speed is maintained.
- - Driving in tr aff ic: The indicator
light - shows that a vehicle moving in
your lane of travel has been detected up
front in your lane of travel. Your speed is ad
justed according to the speed of the vehicle
up front . ACC accelerates and brakes auto
matically within the system's capabilit ies .

_& WARNING
Improper use of the adaptive cruise con
trol features and inattention can lead to a
crash and serious personal injury.
- Never allow the closing speed between
you and othe r vehicles to be so high that
the adaptive cruise contro l may not be
able to slow your vehicle safely. If clos
ing speed is too high, you must apply the
brakes yo urself to reduce the risk of a
rear-end crash.
- Always select a greater following d is
tance to the vehicle up ahead on wet
roads than on dry roads.
- Always read and heed the information
and WARNINGS <=>

System limitations
General information
Applies to vehicles: with adaptive cruise co ntrol
The radar sensor has limits that the driver
must know to be able to use ACC properly .
The adaptive cruise control works within lim its that are also related to radar sensor range
and sight distance . In some situations ACC
may react unusually or late from the driver's
point of v iew. Therefore, always be attent ive
to what is happening around you and always
be ready to intervene, if necessary:
-when driving around curves ¢page 125
- when vehicles up front are not in line with
your vehicle ¢ page 126
- when other veh icles are changing lanes
i=> page 126
- when other vehicles are difficult to detect i=>page 126
- when vehicles up ahead are not moving or obstacles are in your travel lane i=>page 126
A WARNING
The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles up ahead may not be
prompt ly detec ted or may not be detected
a t all.
- Always pay careful att ention to the traf
fic s ituation and be ready to intervene
and be re ady to take comp lete cont rol
whenever necessary.

L e aving a curv e
At the end of very long curves, ACC's predic

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. 146 Display in the instrument cluster
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 deactivated.
A radar sensor is bu ilt into the front of the ve
hicle
¢page 114, fig. 127. The system is in
tended to measure the distance to reflective
surfaces .
If a measurement is not possible,
the system does not respond.
When the measurement 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 application or
by an avoidance maneuver, a warning appears.
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. Braking, transverse acceler
ation and the steering angle can lead to a re
duced system response time. The warning is
deactivated if you begin to overtake with full
acceleration .
Adaptive cruise control 127
The system can make you aware o f two differ
ent hazardous situations:
Distance
The distance warning is given if the system
calculates that there is not enough distance
to the vehicle up ahead a period 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. 146.
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
maneuver. If a warning does sound, a poss ible
collision with the ve hicle in front can on ly be
avo ided through an evasive maneuver or by
braking.
The 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
situation.
Under heavy braking, the brake ass istant
¢
page 114 also helps you benef it from maxi
mum brak ing efficiency.
A WARNING
Inatt ention can cause collisions, other ac
cidents and serious personal injuries.
128 Adapti ve crui se co ntrol
-Always pay close attenti on to t he traffic,
even w hen the Aud i brak ing guard is
switched on. The Aud i b rak ing guard pro
vides a warning but does no t brake the
car for you . You m ust apply t he brakes
yours elf!
- Always ke ep the sa fe and legal distance
betwe en your vehicle and veh icles up
ahead.
-Audi braking guard works within limits and w ill not respond outs ide the system
limits, for examp le when approaching a
stopped vehicle or s tationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember th at the radar sensor
f or the A udi braking guard wo rks within
defined detection and range limits that
may prevent the proper detection of oth
er veh icles.
- 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 al l.
- Always pay careful attention to the traf
fic s ituation and be ready to intervene
and be ready to take comp lete control
whenever necessary.
- Reflective surfaces includ ing crash barri
