General information
Applies to vehicles: with Audi adaptive cruise control and Audi
pre sense front
Fig. 81 Front of vehicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*
r::!>page 103.
The radar sensor area r::!> fig. Bl must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap­
tive cruise control and the pre sense front. For in­
formation on cleaning, refer tor::!>
page 235. The
same applies for any modifications made in the
front area .
The function of the adaptive cruise control sys­ tem and pre sense front is limited in some condi­
tions :
- Objects can only be detected when they are
within the sensor ranger::!>
page 96, fig. 80.
-The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the side of your vehicle or moving into your lane.
- Objects that are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves
r=> page 98.
-With stationary objects r::!> page 98.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
r::!> page 103. As the d riv­
er, you are still responsible for starting and
for maintaining speed and distance to other objects. The pre sense front is used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi­
ble for braking at the correct time.
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
- 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 could result in a collision.
- 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 set 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 pre sense front will
have limited function.
- The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob­
jects.
- 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.
- Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely. The adaptive cruise con­ trol cannot safely slow your vehicle or brake it to a stop if you are driving too close be­
hind a vehicle. Please note that the auto­
matic braking function cannot brake sud­
denly or apply the brakes fully under these
conditions.
- To reduce the risk of unintended actions,
switch the ACC off when you are not actively
using it.

Adaptive cruise control
The adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving. For example, it can
react when a vehicle that has already been de­
tected @turns or changes lanes, but adapt ive
cruise control does not react to a stationary vehi­
cle @. Press the brake pedal to slow your vehicle
down!
Pre sense front
Pre sense front only reacts to stationary objects
at low speeds.

Audi pre sense
Introduction
Applies to vehicles: with Audi pre sense bas ic or Audi pre
sense front
W ith in the limits of the system, p re sense basic
and p re sense fro nt can initiate steps to protect
veh icle o ccupants i n certa in dangerous s itua­
tions.
Critical driving situat ions can be recognized by
the pre sense front v ia a network of differe nt ve ­
h icle systems and can take steps to prepare the
veh icle occ upan ts for a po ten tial coll is ion.
The pre sense front wo rks with a radar sensor and
a video camera*. It also functions within t he lim­
i ts of the system when adapt ive cr uise con trol* is

Audi pre sense basic
Description
App lies to vehicles: wit h Aud i pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or higher .
The following functions can be triggered under certain conditions within the limits of the sys­
tem:
- Tensioning of the safety belts (for example,
during heavy braking): the front safety belts
have reversible belt pretensioners. If a col lision
does not occur, the safety belts loosen slightly
and are ready to trigger again .
- Closing the windows and the sunroof* (for ex­
ample, when over- or understeering): the w in­
dows and the sunroof* close until there is only
a small gap open .
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 des igned to assist
and it cannot p revent a coll ision. Do not let
the increased safety provided tempt you into
taking r is ks. Thi s co uld inc rease your risk of a
collis ion .
- The system can dep loy incorrectly due to
system-specific limits .
(D Tips
-Certa in p re sense bas ic functions switch off
when ESC is switched off (sport mode) o r
w hen driving in reverse. .,.

-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 97.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the funct ion 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 m ind that the radar sensor
for pre sense front only works w ith in de­
fined detection zones, which means other
vehicles may not always be detected correct­
ly.
- 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 a ll.
- 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, whee l hous ing and
underbody. The pre sense front sensor can be
damaged by this . Have an authorized Audi
Assist
dealer or authorized Audi Service Facility
check their function.
(D Tips
- You can cancel the braking with increasing
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 106.
- 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
cruise control* system

at any time. If you pass over a line, the steering
wheel will v ibrate light ly. In order for this warn­
ing vibrat ion to occur, it must first be switched
on in the MMI. Active lane assist is operable
when the lane marker line is detected on at least one side of the veh icle.

The system will not warn you befo re crossing a
l ane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
The system is des igned for driving on express ­
ways and highways and therefore on ly activates
at speeds above approx imately 40 mph (65 km/
h).
A WARNING
-
- The system warns the driver that the vehicle
is leaving the lane using corrective steering .
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself.
Al­
ways keep you r hands on the steering
wheel.
- Corrective steer ing may not occur in certa in
situa tions, su ch as during heavy braking.
- There may be cases where the camera does
not recognize all lane ma rker lines. Correc­
tive stee ring can only take p lace on the side
of the vehicle where lane marker line5 are
detec ted.
- Othe r road structures or obje cts cou ld possi­
b ly be identified un intent ionally as lane
marker l ines . As a result, corrective steering
may be unexpected or may not occur .
- The camera view can be restricted, for ex ­
ample by vehicles driving ahead or by rain,
snow, heavy spray light shining into the
camera or by d irt on the window. This can
result in active lane ass ist not detecting the
lane marker lines or detecting them incor­
rectly.
- In certain situat ions where visibility is low,
the vehicle may switch from "early" to "late"
corrective steering
l l.
- Under certain co nditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steering a lone may not be enough
to keep the vehicle in the midd le of the lane.
