Audi pre sense
Introduction
App lies to: vehicles with Audi pre sense
Within the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the vehicle pas­
sengers and other road users.
- Due to the interlinking of various vehicle sys­
tems, critical driving situations can be detected by
pre sense basic and measures for preventa ­
t ive occupant protection are can be initiated .
- The
pre sense front system uses the data from
the adaptive cruise control* radar sensors and
the camera to calculate the probability of a col­
li sion. 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 initiat e a partial or full
deceleration to reduce the collision speed or to
avoid the collision under certain circumstances .
I n conjunction with pre sense basic/rear, the
front safety belts are also revers ibly tensioned
when needed . The pre sense front is also active
when adapt ive cruise control* is switched off .
-Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra­
dar sensors and calcu lates withi n the limits of
the system the probability of a rear end coll i­
sion with the vehicle beh ind you. Pre sense rear
is also active when side assist* is switched
off.
- Within the limits of the system, pre sense city
uses the camera data and can detect an im­
pending collision with vehicles and pedestrians.
In this case, the system warns the dr iver visual­
ly, acoustically and with a jerk on the brakes if
necessary. If needed, it can initiate a full decel­
eration to reduce the collision speed or to avoid
Assistance systems
the collision under certain circumstances. In
conjunction with pre sense basic/rear, the front
safety belts are a lso reversibly tens ioned when
needed .
A WARNING
Read the genera l information in c:>&. in Gen­
eral information on page 114,
c:> &. in Gener­
al information on page 135.
(D Tips
- Certain pre sense functions switch off when driving in reverse.
- The pre sense functions may not be availa­ ble if there is a malfunction in the ESC sys­
tem or the airbag control module.
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated .
- Switch the pre sense
off when you a re not
using public streets or when loading the ve­
hicle onto a vehicle carrier, tra in, sh ip or
other type of transportat ion. This can pre­
vent an undesired inte rvention from
the pre
sense system.
Audi pre sense basic
Description
Applies to : vehicles with Audi pre sense basic
The pre sense basic functions are activated at a
speed of approx imately 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 examp le,
during heavy braking): the front safety belts have reversible belt tensioners . If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger aga in .
- Closing the windows and sunroof* .

your steering wheel ang le as long as you a re ac­
tively steer ing . Evasive steering support is availa­
ble at speeds between approximately 20 mph
(30 km/h) and 90 mph (150 km/h).
Tu rn as sist
When starting to drive a nd 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 tu rning
left or right (available in certain countries). The
braking intervention 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
stance. The drive r must always i nte rvene.
T he driver is always responsib 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 collision .
- The system can deploy incorrectly due 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
imals or objects that are cross ing the veh i­
cle's path or that are difficu lt to
detect¢ &
in General information on page 114 .
-Reflective objects such 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 collis ion risk .
@:) Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Pre sense front can be impa ired
by this . H ave an autho rized Aud i dealer or au­
thorized Audi Service Fac ility check their func­
tion .
l) Th is is no t a va ilable in som e countries.
A ss ista nce sys te m s
{!) 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.
- 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.
- Certa in pre sense front funct ions are switch­
ed off when the ESC is limited or switched
off

Audi pre sense city
Description
A ppl ie s to: ve hicles w ith Aud i p re se nse c ity
Within the limits of the system, pre sense city
can warn you of impending collisions with
vehicles and pedestrians and initiate the applica­
ble braking maneuver if needed. Pre sense city is
active at speeds of approximately 6 mph (10 km/ h) and higher .
A pedestrian warning can occur at speeds up to
SO mph (85 km/h), and vehicle warnings can oc­
cur at speeds up to 155 mph (250 km/h). A pre
sense city braking maneuver is poss ible at speeds
up to SO mph (85 km/h).
Warnings
A ppl ies to: ve hicles w ith Aud i p re sense c ity
The system recognizes various dangerous situa­
tions. The
early warning occurs if:
- a veh icle driving ahead brakes suddenly,
- your own vehicle approaches a significantly
slower vehicle or stationary vehicle in the direc­
tion of travel.
- a pedestrian is standing in the lane or is moving
into the lane .
When this warning occurs, it may only be possi­
ble to avoid a collision by swerving or braking
strongly . The message

128
¢ page 126, fig. 126 and a warning tone will
warn you about the danger.
Additionally, a jerk on the brakes may occur as an
acute warning when there is an impending colli­
sion . If you do not react to the acute warning, pre
sense city can brake to the point of complete de­
ce leration within the limits of the system . This
reduces the vehicle speed in the event of a colli­
sion. The message

3 a,
-If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case , the
system may have detected a veh icle in another
lane that is
not adjacent to your current lane.
-If you are driving through a curve . Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
-If side assist reacts to other objects (such as
roadside structures like guard rails).
-In poor weather conditions . The side assist
functions are limited.
Do not cover the radar
sensors ¢ fig. 134 with
stickers, deposits, bicycle whee ls or other ob­
jects, because this wi ll impa ir the function. Do
not use side assist when towing a trailer. For in­
formation on cleaning, see
¢page 362 .
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot replace a dr iver's attention. The dr iver alone
is a lways responsib le for lane changes and
similar d riving maneuvers.
-In some situat ions, the system may not
function or its funct ion may be limited. For
example:
-If vehicles are approach ing or being left
behind very quickly. The display may not
turn on in t ime.
-In poor weather conditions such as heavy
rain, snow or heavy mist.
-On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outs ide of the sensor
range.
