Assist
(D Note
The sensor can be displaced by impacts or
damage to the bumper , whee l housing and
underbody. The adaptive cruise control and
pre sense front may become impaired as a re­
sult . Have an authorized Audi dealer or au­
thorized Audi Service Fac ility check their func­
tion .

Adaptive cruise control
The adaptive cruise control system only reac ts to
objects that are moving or that the system has
already detected as moving. For example, if a de­
tected vehicle @turns or changes lanes, the
adaptive cruise contro l will not react to a stopped
vehicle @. Press the brake pedal to slow your ve­
hicle down.
Pre sense front
Pre sense front only reacts to stationary objects
at low speeds.

When approaching an object detected ahead, the adaptive cruise contro l system brakes to match
that object's speed and then regu lates to the
stored distance. If the object detected ahead ac­ celerates, adaptive cruise control will also accel­
erate up to the stored speed.
The higher the speed, the greater the distance in
meters

Audi pre sense
Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre sense front
With in the limits of the system, p re sense basic
and pre sense front can in it iate steps to protect
vehicle occupants in certain dangerous s itua­
tions .
Critical driving situat ions can be recogn ized by
the pre sense front via a network of different ve­ hi cle systems and can take steps to prepare the
ve hicl e o ccupants for a potential collis ion.
The pre sense front works w ith a radar sensor
and a video camera*. It also functions within the limits of the system when adaptive c ruise con­
tro l* is switched off .

Audi pre sense basic
Description
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or h igher .
The following functions can be triggered under certain condit ions w ith in the lim its of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy braking): the front safety belts have reversib le be lt tens ioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to tr igger aga in.
- Closing the windows and the sunroof* (for ex­
ample when over- or understeering): the win­
dows close until the re is only a small gap open
and the s unroof* closes all the way .
Audi drive select: the deployment time is adapt­ ed in dynam ic mode.
_&. WARNING ~
The pre sense basic cannot overcome natural
physical laws. It is a system desig ned to ass ist
and it cannot p revent a collision. Do not let
the increa sed safe ty p rovided tempt you into
t aking r is ks. This co uld in crease yo ur risk of a
collis ion .
- The system can dep loy inco rre ctly due to
system-specif ic limits.
(D Tips
- Certa in p re sense basic functions switch off
when ESC is swi tched off (sport mode) or
w hen driving in reverse. .,.

Audi pre sense front
Description
A pp lies to veh icles: with Audi pre sense front or Audi adapt ive
cr uise control
Pre sense front informs you if the distance to the
vehicle ahead falls below the safe distance for an
extended period of time.
It c an warn of a poss i­
b le co llision and initiate braki ng maneuve rs,
within the limits of the system.
When detected in time, the system can assess
dangerous s ituations where an object ahead
b rakes suddenly or if your own vehi cle is t raveling
at a high speed and approaching an object that is
mov ing more slowly. If detect ion is not possible,
then pre sense front does not react.

ahead is traveling more slowly or brakes
strong ly. When this warning occurs, it may only
be possible to avoid a coll is ion by swerving or
braking strongly. The message

• c:> fig. 125 and a warning tone will warn you
about the danger. For vehicles with adaptive
cruise control, the. indicator light also turns
on .
If you do not react enough or not at all to a da n­
gerous s ituation that was detected by the sys­
tem , pre sense front provides assistance by ap­
plying t he b rakes .
- If a collision is imminent, the system will first
prov ide an
acute w arning by braking sharply .
You will also be made aware of the danger by the ins trument cluste r display
c:> fig . 125. For
veh icles with adaptive cru ise cont rol, the . in­
dic ator light a lso tu rns on .
- If you do not react to the acute warning, pre
sense front can brake w ith increasing force
w it hi n the lim its of the system
l )_ This reduces
the vehicle speed in the event o f a collis ion . The
message

- At low driving speeds, pre sense front can begin
complete deceleration shortly before a
co llision
l).
- If p re sense front determines t hat you are not
braking strongly enough when a co llision is im­
m inent, it can increase the braking force.
A WARNING
-
- Pre sense front cannot overcome natura l
phys ica l laws. It is a system designed to as ­
sist and it cannot prevent a collision . The
driver m ust always intervene . The dr iver is
always responsible fo r braki ng at the correct
time . Do not let the in crease d sa fety prov id­
ed tempt you into ta king risks. This could in­
crease your risk of a collision .
- The system can dep loy inco rre ctly due to

,....,
N
0 > co ,...., -Please note that the sensor does not always
detect all objects. This increases the risk of
a collision.
- Pre sense front does not react to people or
animals or objects that are crossing the ve­
hicle's path or are difficult to detect
¢ page 133.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensor and
the system's ability to detect a collision risk.
- Lack of attention can lead to collisions, oth­
er accidents and serious injuries. pre sense
front is an assistance system and cannot
prevent a collision by itself. The driver must
always intervene. The driver is always re­
sponsible for braking at the right time.
- Always pay attention to traffic, even when
pre sense front is switched on. Always be
ready to intervene and take over complete
control of the vehicle whenever it is neces­
sary. Always follow traffic laws regarding
maintaining a safe distance between your
vehicle and vehicles ahead.
- pre sense front works within certain limits
and cannot react to situations that are out­
side of the system limits, such as when ap­
proaching a stationary vehicle or a station­
ary obstacle (the end of a traffic jam or ave­
hicle that has broken down).
- Always keep in mind that the radar sensor
for pre sense front only works within de­
fined detection zones, which means other
vehicles may not always be detected cor­
rectly.
- The function and range of the radar sensor
can be impaired by rain, snow and heavy
mist. Vehicles ahead may not be detected
right away, or not detected at all.
- Reflective surfaces such as guard rails or en­
trances to tunnels may impair the function
of the radar sensor.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense front can be impaired
by this. Have an authorized Audi dea ler or au-
Assist
thorized Audi Service Facility check their func­
tion.
(D Tips
- You can cancel the bra king with increas ing
force that is initiated by the system by brak­
ing yourself, by acce lerating noticeably or
by swerving.
- For information on driver messages about
pre sense, refer to¢
page 142.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
- Certain pre sense front functions switch off
when ESC is switched off (sport mode) or
when driving in reverse.
- The pre sense front functions are not availa­
ble if there is a malfunction in the adaptive
