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 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

Description
Applies to: vehicles with Audi drive select
The following systems, among other things, are
influenced by drive select:
Engine and automatic transmission*
Depending on the mode, the engine and auto­
mat ic transmission* respond more quickly or in a
more balanced manner to accelerator pedal
movements. In the sporty
Dynamic mode, the
transmission shifts at highe r speed ranges.
Suspension control*
The suspension control* uses sensors to record
information regarding steering movements,
braking and acceleration operations by the driv­
e r, road sur face, dr iv ing speed, and load. This
makes it possible to adapt damping to the driv­
ing situation nearly in rea l time. With drive se ­
lect, you can adjust the suspension control to be
sporty
( Dynamic ), comfortab le ( Comfort ) or bal­
anced
( Auto ).
Steering
The power steering adapts. Indirect steer ing that
moves easi ly as in
Comfort mode is especia lly
suited to long drives on highways. The
Dynamic
mode provides sporty, direct steering.
The following applies to vehicles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the driver at all times. This
sets the steer ing to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, steering is more direct in
order to keep the steering effort as min imal as
possible w hen the driver is maneuvering the vehi­
cle . At low and average speeds, dynam ic steer­
in g* add itionally provides more responsive steer­
ing performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 154, the sport differential dis­
tr ibu tes the dr iv in g power to the rear ax le de­
pending on the situation. The distribution of
power varies depending on the selected mode
Assistance systems
from moderate (Comfort ) to sporty (Dynamic ).
The goal is a high level of agility and ability to ac­
ce lerate on curves . T he vehicle is very responsive
to steering.
Adaptive cruise control (ACC)*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
(D Tips
The S selecto r lever position automatically en­
gages when the
Dynamic mode is selected .
Selecting the driving mode
Applies to: vehicles with Aud i drive select
Fig . 139 Cen ter co nsole: con trols for d rive se lect
.. Press the left or right a rrow key ~fig. 139 until
t he desired mode appears in the instrumen t
cluster/ Infotainment system display. Or
.. Select in the Infotainment system: I MENU ! but-
ton

.. Select and confirm the desired setting .
You can change the driving mode when the vehi-
cle is stationary or while driving. If traffic per-
mits, after changing modes, briefly take your
foot
off the accelerator pedal so that the recently
selected mode is also activated for the engine.
Comfort -provides a comfort-oriented vehicle
setup and is suit ed for long drives on highways.
