On open roads with no traffic, it functions like a
cruise control syst em . Th e stored spe ed is main­
tained. When approach ing a veh icle driving
ahead, the adaptive c ruise control system auto­
mat ica lly brakes to mat ch that vehicle's speed
and then maintains the set distance . As soon as
the system does not detect a vehicle driving ahead, adaptive cruise contro l accelerates up to
the stored speed.
In stop -and -go traff ic, adaptive cru ise control can
brake unt il the vehicle is stat io nary and then can
also start driving again automatically under cer­
tain
condi tions ¢ page 106.
In traffic jams or stop -and -go traffic, traffic jam
assist can assist the
driver ¢ page 109 .
Which function s can be contr olled ?
When you switch adapt ive cruise control on, you
can set the current speed as the "control speed"
¢ page 104, Swi tching on/off.
When driving, you can stop c ruise contro l
¢ page 107 or change the speed ¢ page 106 at
any time.
You can a lso set the distance to the vehicle driv ­
ing ah ead and s et the driv ing mode of the adap­
tive cruise
control ¢ page 10 7.
General information
Applies to: ve hicles with Audi adaptive cruise co ntro l
Fig. 10 0 Fro nt of the v ehi cle : se nso rs a nd v ideo cam era
The areas w ith the rada r and u ltrasonic sensors
and the video
camera ¢ fig. 100 must not be cov­
ered by stickers, deposits or any other objects ,
because this can interfe re with the adapt ive
cru is e control funct ion. For information on clean-
A ssi st a nce systems
ing, see ¢ page 344 . The same applies fo r any
modifications made in the front area .
In some dr iving s it u ations, the adaptive c ruise
contro l func tion is restricte d:
- Veh icles can on ly be de tected when they are
w ith in the sensor detection zones
¢ page 102,
fig.
99 .
- The system has a limited ability to detect
ve hicles that are a short dis tance ahead, off to
t he side of your ve hicle or movi ng i nto yo ur
lane.
- Ob jects that are d ifficult to detect s uch as mo­
torcycles, veh icles with high gro und clea rance
or an overhanging load are detec ted late or not
detected at all.
- When driving through curve s
¢page 104 .
-W he n the veh icle is sta tionary r=;, page 104 .
A WARNING
Always pay at ten tion to the traffic around you
when adaptive cru ise con trol is switched on .
As the driver, you are still responsible for your
own speed and the d istance to other veh icles.
The adaptive cruise cont rol is used to assist
you. The driver must always take action to
avoid a collision . The driver is always responsi ­
bl e for braking at the correct t ime.
- For safety reasons, do not use adaptive
cr uise control when the road surface is in
poor condi tion and/or in bad weather condi­
tions (such as ice, fog, gravel, heavy rain and
hyd roplani ng) . Using the system under
these co ndi tions i ncrea ses the r is k of an a c­
cide nt.
- Sw itch adaptive cru ise con trol
off tempora­
r ily when dr iv ing in tu rning lanes, on e x­
p re ssway ex its (except if predictive con trol
is switched on) or in construct io n zones .
This prevents the vehicle from acce lerating
to the stored speed w hen in these situa­
tions.
- The adaptive cruise contro l system will not
brake by itself if you put yo ur foot on the ac­
celerator pedal. Doing so can over ride the
speed and d ista nce regulation .

Assistance systems
-When approaching stationary obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function.
- Adaptive cruise control does not respond to
people, animals, or cross ing 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.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody . Th is can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
function.
@ Tips
For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
¢page 374.
In curves
Applies to: vehicles w ith Audi adaptive cruise control
Fig . 101 Example: driving into a curve
When driving into a curve ¢ fig. 101 and out of a
curve, the adaptive cruise control may react to a
vehicle in the neighboring lane and apply the
brakes. You can prevent that by pressing the ac­
celerator pedal briefly.

Stationary vehicles
Applies to: vehicles with Audi adapt ive cruise control
))
Fig . 102 Example: vehicle changing lanes and stationary
vehicle
Within the limits of the system, adaptive cruise control can react to stationary vehicles
¢
fig. 102, as long as you are driving slower than
30 mph (SO km/h) and the system classifies the
possible passing maneuver as low . For example,
if a vehicle that was already detected
(D turns or
c h anges lanes, the adaptive cruise control reacts
to the stationary vehicle ahead of
it @ .

Audi pre sense
Introduction
Applies to: ve hicles w ith Audi p re se nse
W ith in the limits of the system, the pre sense
functions can in it iate measures in particularly
dangerous s ituat ions to protect the ve hicle pas ­
sengers and ot her r oad users.
- Due to the interl ink ing of various vehicle sys­
tems , crit ica l dr iv ing s ituat ions can be detected
by
pr e s ense basic and measu res fo r preventa­
t ive occ upan t protect ion are can be initiated.
- T he
pre sen se front system uses the data from
t h e adapt ive cr uise control* radar sensors and
t h e camera to calc ulate the probab ility of a col ­
lision . Within the limits of the system, an im ­
pending collision with vehicles can be detected
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary . If needed, it can initiate a partial or fu ll
deceleration to reduce the collision speed or to
avo id the co llision unde r ce rtain c ircumstances .
In conjunct ion with p re sense basi c/rear, the
front safety belts are also revers ibly tensioned
whe n needed. The pre sense front is also act ive
when adaptive cruise control* is switched o ff.
- Pr e se nse rear con tains pre sense basic func ­
tions. It uses the data from the side assist* ra­
dar sensors and calc ulates within the limits of
the system the probability of a rear end colli ­
sion with the vehicle behind you . Pre sense rear
is also active when s ide assist* is switched off .
112
-Within the limits of the system, pre sen se cit y
uses the camera data and can detect an im ­
pending collision with vehicles and pedestrians .
In this case, the system warns the driver visual­ ly, acoustical ly and w it h a jerk on the brakes if
necessary . If needed, it ca n initiate a full dece l­
erat ion to reduce t he coll is ion speed or to avoid
the collision under certa in circumstances . In
conjunction with p re sense basi c/rear, the front
safety belts are a lso reve rsibly te nsioned whe n
needed.
& WARNING
Read the genera l information inc::> .&. in Gen ­
eral information on page 103,
~ .&. in Gener ­
al information on page 122.
(D Tips
- C erta in p re sense funct io ns sw itch off when
driving in reve rse.
- Th e pre sense f unct io ns m ay no t be ava ila ­
ble i f th ere is a ma lfunct ion in the ESC sys ­
tem or t he airbag control module .
-Note that the reve rsib le belt tens ione r o n
the front passenger 's side deactivates when
the front passenger's airbag is deactivated.
- Switch the pre sense off when yo u are not
using public streets or when loading the ve ­
hicle onto a vehicle carrier, train, ship or
other type of transportat ion. This can pre­
vent an undesired intervention from the pre
sense system.
Audi pre sense basic
App lies to: vehicles wit h Audi pre sense basic
The pre se nse bas ic functions are activated at a
speed of approx imately 20 mp h (30 km/h) o r
highe r.
The following functions ca n be triggered u nder
certain co nd it io ns w it hi n the lim its of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy brak ing) : the front safety belts
have reversible belt te nsioners . If a collision
does not occur , the safety belts loosen slig htly
and are ready to tr igger aga in.
...

Ass is tanc e system s
Turn a ssist
When start ing to dr ive and up to speeds of maxi­
mum 6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning left or right (available in certain co untries). The
braking intervent ion causes your vehicle to stay
in its lane.
A WARNING
-Pre sense front cannot overcome the laws of
physics . It is a system des igned to assist and
it cannot prevent a collision in every circum­
sta nce. The d rive r must a lways i ntervene.
T he d river is always respons ib le for b raking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This cou ld increase your risk of a co llision .
-The system can deploy incorrectly d ue to
system -specific limits .
-Please note that the sensors and the camera
do not always detect all objects or lane
markings. This increases the risk of an acci ­
dent.
-Pre sense front does not react to people, an ­
ima ls or ob jects that are crossing the veh i­
cle's path or that are diff icu lt to detect
c::> &
in General information on page 103.
-Reflective ob jects s uch as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a coll is io n risk.
{UJ) Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody . Pre sense fro nt can be impa ired
by this. Have an authorized Aud i dealer or au­
thori zed Aud i Service Fac ility check the ir func­
tion.
