Audi adaptive cruise
control
Description
A pp lies to: ve hicles w ith Audi adaptive cruise co ntro l
F ig. 88 Detection range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the dr iver by bot h regula ting the speed and
maintaining 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 accelerate your vehicle.
This makes driving more comfortable both on
long stretches of hig hway and in stop-and-go
traffic .
What c an adapti ve crui se control do ?
The adaptive cruise contro l system uses video, ra­
dar and ultrasound. Objects driving ahead can be
recognized up to 650 feet (200 m) away.
On open roads with no traffic, it functions like a
cruise control system . The stored speed is main­
tained. When approaching an object ahead, the
adaptive cruise control system automatically brakes to match that object's speed and then
maintains t he stored d istance . As soon as the
system does not detect an object ahead, adaptive
cru ise control acce lerates up to the stored speed .
In stop-and-go traffic, adaptive cru ise control can
brake unt il the vehicle is stat ionary and then be­
g in driving aga in under certain conditions
c::> page89.
Audi braking guard can war n you about an im ­
pending collision and initiate brak ing maneuve rs
<=:> page 91 .
86
Which functions can be controlled?
When you switch ad apt ive cr uise control on, you
can set the current speed as the "control speed"
c::> page 88, Switching on/off.
When dr iving, you can stop cruise cont rol
¢ page 90 or ch ange the speed c::> page 89 at
any time.
You can also set the distance to the object mov­ i ng ahead and se t the driving mode of t he adap­
tive cr uise
control¢ page 90.
General information
App lies to : vehicles wi th Audi adap tive c ruise con trol
Fig. 89 Fro nt of th e vehicle: senso rs a nd video camera
The areas that contain the rada r and ultrasonic
senso rs and the video camera
c::> fig . 89 must not
be covered by stickers, deposits or o ther objects
because this can interfere with the function of
the adapt ive cruise control system and braking
guard . For info rmation on clea ning, see
¢ page 221. The same applies for any modif ica­
tions made in the front area.
The function of the adaptive cru ise control sys­
tem and braking guard is limited under some
cond itions.
- Objects can only be detected when they are
w ith in the sensor range
<=:>page 86, fig. 88.
- The system has a l imi ted abili ty to detect ob­
jec ts that are a sho rt d istance ahead, off to the
side of your vehicle or moving into your lane.
- Obje cts that are d ifficult to detect such as mo­
torcycles, veh icles with high ground clea rance
or an overhanging load are detected late or not
detected at all.
- When driving through curves

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
Assistance systems
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.

Ass is tanc e system s
What can the braking guard do?
When detected in t ime, the system can assess
dangerous situations where an object ahead
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is moving more slowly. The braking guard does not
react if it cannot detect the s ituation.
The system advises you of various dangerous sit­ uations :
- T he
dista nce warning occurs if you d rive too
closely to the object ahead for a long period of
time. If the object ahead brakes strongly, you
would not be able to avoid a collision .
The.
indicator light appears as an indication for this.
- The
app ro ach warning occurs when an object
ahead is traveling more slow ly or brakes
strongly. When th is warning occurs, it may only
be possible to avoid a co llision by swerv ing or
braking strongly . The danger is indicated by the
• ind icator light ¢ fig . 98 . An aud io signal w ill
also sound .
If you do not react early enough or at all to a dan­
ge rous situation, the braking guard suppo rts you
with a brak ing intervention .
- If a collision is imminent, the system will f irst
provide an
a cut e warn ing 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 vehicle speed in the event of a collision .
- The system can init iate comp lete deceleration
shortly before a collision
ll _ Full deceleration at
high speeds occurs only in vehicles with adap­
tive cru ise control and s ide ass ist (pre sense
pl us).
- If the braking gua rd determines that you are
not brak ing strongly enough whe n there is an
im pending co llision, it can increase the bra king
force .
- T he pre sense functions also engage whe n
t h ere is an impend ing collision ¢

Which fun ction s can be controlled?
Yo u can swi tch the braking guard and the d is­
tance/approach warning on or
off in the Infotain ­
ment system ¢
page 93, Settings in the Info ­
tainment system .
A WARNING
Lack of attention can cause collisions, other
accidents and ser ious personal injuries . The
braking guard is an assist system and cannot
prevent a collis ion by itself . The dr iver must
a lways intervene. The d river is always respon­
sib le for braking at the co rrect t ime.
- Always pay close attention to traffic, even
when the b raking guard is sw itched on. Be
ready to intervene and be ready to take
co mplete co ntro l whenever necessa ry . Al ­
ways keep the sa fe and legal distance be ­
tween your vehicle and ve hicles up ahead .
- Br aki ng g uard wo rks w ithin limits and w ill
no t respond outside the system limits, for
examp le when approaching a stopped vehi ­
cle or stationary obstacle (end of a traffic
jam or ve hicle that has broken down in traf ­
fic).
- Always remember that the radar sensor for
the brak ing guard works only within defined
detection and range limits that may prevent
the proper detection of other vehicles .
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Mov ing veh icles up ahead may not be
promptly detected or may not be detected
at al l.
- Reflective surfaces including crash ba rr iers
or tunne l entra nces may impair the function
of the rada r senso r.
(D Tips
- You can cancel the braking with increas ing
force that is initiated by the system by brak­ ing yourse lf, by acce le rating not iceably or
by swerv ing.
- Keep in mind that b raking gua rd can b rake
unexpectedly. A lways secure a ny cargo or
