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* .

Audi pre sense front
Description
A ppl ies to: ve hicles w ith Audi a daptive cruise co ntrol
W ith in the limits of the system, pre sense front
can warn you of impending coll is ions and initiate
t he corresponding brak ing maneuvers or the sup­
port ing measures when avo iding a collision .
I f detected in time, the system can rank the dan­
ge rous situation as cr itical if a ve hicle driving
a head brakes s udden ly, if your own vehicle is ap­
p roaching a s ignificantly s lower vehicle at high
speed or when there is an oncom ing vehicle d ur­
i n g a t urning maneuve r.
If detection is not poss ible , the n pre sense front
does not react .

General information
The system recognizes var ious dangerous situa ­
tions. The
early warning occurs if:
-a veh icle d riving ahead brakes s uddenly,
- yo ur own vehicle ap pro aches a signific antly
s lower vehicle o r stationary ve hicle in the direc­
tion o f travel.
l) Thi s is not a va ilab le in some co untri es .

¢ fig. 126 and a wa rning tone will warn you
about the danger .
If you do not react enough or not at all to a dan ­
gerous s ituat ion that was detected by the sys­
tem, pre sense front provides assistance by ap­ plying the b rakes.
If a collision is imminent, the system will fi rst
provide an
acute warning by b raking sharply . You
will a lso warned by an indicato r in the instrument
cluster

The followi ng func tions trigge r in conjunc tion
with pre sense basic/ rear at corresponding vehi ­

-Reversible tens io nin g of the front s afety bel ts.
-Clos ing t he windows and sun roof* .
-Infla ting t he side bols ters* on the seat back-

Audi active Lane assist
Description
Applies to : vehicles wi th A udi act ive la n e ass ist
Active lane ass ist (lane departure warning) de­
tects lane marker lines within the l imits of the
system using a camera in the windshield . If you
are approach ing a detected lane marker l ine and
it appears likely that you will leave the lane, the
system w ill warn you with corrective steering.
You can override this steering at any time. If you pass over a line, the steering whee l will vibrate
lightly . In order for this warn ing v ibration to oc­
cur, it must first be sw itched on in the Infotain­
ment system. Act ive lane assis t is ready for oper­
ation when the lane marker line is detected on at
least one side of the veh icle .
The system is designed for driving on express­ ways and h ighways and therefore only activates
at speeds above approx imately 40 mph (65 km/
h).
Applies to: vehicles with side assist: if you acti­
vate a turn s ignal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach­ i n g you, the re w ill be noticeable corrective steer­
i n g shortly before you leave the lane. This will at­
tempt to keep your veh icle in the lane.
Applies to: vehicles without side assist: the ready
system does not wa rn you if you activate a turn
signal befo re cross ing the lane marker line. In
130
this case, it assumes that you are chang ing lanes
intentionally .
Applies to: vehicles with adaptive cruise control:
there is no corrective steer ing or warnings if the
system recognizes a dist inct passing maneuver .
If the conditions are met, traffic jam assist
switches on at speeds under approximately
40 mph (65
km/h) ¢ page 121.
A WARNING
,-
- The system warns the driver that the vehicle
is leaving the lane using correct ive 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 itse lf . Al­
ways keep your hands on the steering
wheel.
- Cor rective steering may not occur in certain
situations, such as du ring heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive stee ring can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Othe r road structures or objects could poss i­
bly be identified un intent ionally as lane
marker lines . 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 or light shining into the
camera. This can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- In certain s ituations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correction .
- Under certain cond it ions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the m iddle of the lane .
- For safety reasons, act ive la ne assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the

potential for hydroplaning. Using active lane
assist under these conditions may increase
the risk of a crash.

- The relevant lane marker lines are not detected
(for example, markings in a construction zone
or because they are obstructed by snow, dirt,
water or light ing) .
- The vehicle speed is below the activation speed of approximately 40 mph (65 km/h).
- The lane is too narrow or too wide.
- The curve is too narrow.
- The driver's hands are not on the steering
wheel.
