0 00 <..:l ' Audi adaptive cruise control
Description
Applies to: vehicles with Audi adaptive cruise control
Fig . 8 9 Detectio n ra n ge
The adaptive cruise co ntro l system is a comb ina­
tion of speed and d istance regula tion.
It assists
the dr iver by bot h regula ting the speed and
main taining a distance to the vehicle driving
ahead , within the limits of the system . If the sys­
tem detects and object ahead, adaptive cruise
control can brake and acce lerate your vehicle.
This makes driving more comfortable both on long stretches of highway and in stop-and-go
traffic .
What can adaptive c rui se control do?
T he adaptive cruise contro l system uses video, ra ­
dar and ultrasound . Objects driving ahead can be
recogni zed up to 650 feet (200 m) away.
On open roads with no traffic, it functions like a
cru ise control system . T he stored speed is ma in­
tained. When approaching an object ahead, the
adapt ive cruise control system automatically
brakes to match that object's speed and then
maintains the stored d istance. As soon as the
system does not detect a n object ahead, adaptive
cru ise con trol a cce lerates up to the stored speed .
In stop-and -go traff ic, adaptive cru ise control can
brake unt il the vehicle is s tat io nary and then be­
g in d riving aga in under certai n conditions
¢ page 90.
Aud i braking guard can warn you about an im ­
pending col lision and in itiate braking maneuve rs
q page92 .
Assi st a nce systems
Which functions can be controlled?
When yo u switc h adap tive cr uise control on, you
can set the current speed as the "contro l speed"
¢ page 89, Switching on/off .
When driving, yo u can stop cru ise cont rol
¢ page 91 or ch ange t he speed ¢ page 90 at
any t ime .
Yo u can also se t the distance to the object mov­
i ng ahead and set the d riving mode of the adap­
t ive cr uise con trol ¢

Assistance systems
-With stationary objects ¢ page 89.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision. The
driver is always responsible for braking at the
correct time.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing). Using the system under these condi­
tions increases the risk of an accident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations .
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani­
mals, objects crossing the road or oncoming
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
A WARNING
- Improper use of adaptive cruise control can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adaptive cruise control and braking guard
88
offer distract you from the need to be alert
to traffic conditions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warning and if confirmed by the
video camera, an acute collision warning.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The adap­
tive cruise control cannot slow or brake the
vehicle safely when you follow another vehi­ cle too closely. Always remember that the
automatic braking function cannot bring the
vehicle to a sudden or emergency stop un­
der these conditions .
- To prevent unintended operation, always
switch ACC off when it is not being used .
@ Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive
cruise control system and braking guard .
Have an authorized Audi dealer or authorized
Audi Service Facility check their function.

" N .... 0 00 \.J ' What can the braking guard do?
When detected in time, the system can assess
dangerous sit uat ions where an object a head
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is
mov ing more slowly. The brak ing guard does not
react if it cannot detect the situation.
The system advises you of various dangero us sit­
uations :
- T he
distan ce warning occurs if you d rive too
closely to the object ahead for a long period o f
time . If the object ahead brakes strongly, you
would not be able to avoid a collision .
The.
indicator light appears as an indication for th is.
- The
app roach wa rning occurs when an object
ahead is traveling more s low ly or brakes
strongly. When th is warning occurs, it may on ly
be poss ible to avoid a co llision by swerving or
braking strongly . The danger is indicated by the
• ind icator light ~ fig . 99 . An aud io signal w ill
also sound .
If you do not react early enough or at a ll to a dan­
ge rous situation, the braking guard suppo rts you
w ith a brak ing intervent ion .
- If a co llision is imminent, the system will first
provide an
ac ute warning by braking sharply.
- If you do not react to the acute warning, the braking guard can increase the braking force
within the limits of the system
ll . Th is reduces
the veh icle speed in the event of a collision .
- The system can init iate comp lete decelerat ion
shortly before a collision
l l. Full deceleration at
high speeds occurs only in vehicles with adap­
t ive cru ise control and s ide ass ist (pre sense
plus).
- If the braking gua rd determines that you are
not brak ing st rongly eno ugh whe n there is an
i mpending co llision, i t can increase the brak ing
fo rce .
- T he pre se nse functions also engage whe n
the re is an impend ing
collision ~ page 95.

ment system
~ page 94, Settings in the Info­
tainment system .
A WARNING
--
Lack of attention can cause collisions, other
accidents and ser ious personal inj uries. The
braking guard is a n assist system and cannot
pr event a collision by itself . T he dr iver m ust
a lways inte rvene . The d river is always respon­
s ib le for b raking at the co rrect t ime.
- Always pay close atten tion to traffic, even
when the b raking gua rd is switched on. Be
ready to in tervene and be rea dy to take
comp le te co ntro l wheneve r ne cess ary. A l­
ways keep the sa fe and legal distance be ­
tween your vehi cle a nd ve hicl es up ahead .
- B raki ng g uard works w it hi n limi ts a nd will
not respond o uts ide the system limits, fo r
examp le when approach ing a stopped veh i­
cle or stationary obstacle (end of a traff ic
jam or vehicle that has broken down in traf ­
fic).
- Always remember that the radar sensor for
the brak ing guard works only within def ined
detection and range limits that may prevent
the proper detect ion of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Mov ing vehicles up ahead may not be
promptly de tected or may no t be detected
at a ll.
- Reflective surfaces includi ng crash ba rriers
or tunne l entra nces may impair the function
of t he ra da r se nso r.
(D Tips
- You can cancel the braking with increas ing
force tha t is initiated by t he sys tem by brak­
ing yourse lf, by acce le ra ting not iceably or
by swe rving.
- Keep in mind that b raking gua rd can b rake
unexpectedly. A lways secure a ny cargo or
