What can adaptive cruise control do?
The adaptive cruise control system uses rada r
and a video camera. The radar is subject to
designated system limits ¢ page 87.
On open roads w ith no traffic, it functions l ike
a cruise control system . Th e stored speed is
maintained . When approaching an object
ahead and the system detects it, the adaptive
cr uise control system automatically brakes to
match that object's speed and then maintains
the stored distance. As soon as the system
does not detect an object ahead, adaptive
cru ise control accelerates up to the stored
speed .
With in the limits of the system, adaptive
cru ise control can brake in stop-and-go traff ic
until the vehicle is stationary and then begin
driving aga in under certa in conditions
¢ page 91, Driving in stop-and-go traffic.
Which functions can be controlled?
When you switch adaptive cruise control on,
you can set the current speed as the "control speed" ¢ page
89, Switching on/off.
When driving, you can stop cruise control
c::> page 91 or change the speed c::> page 90
at any time .

Audi pre sense Introduction
Applies to vehicles: with Audi pre se nse basic or Aud i pre
sense front
W ithin the limits of the system, pre sense ba­
sic and pre sense front can initiate steps to
protect vehicle occupants in certa in danger­
ous situations.
Critical driving situat ions can be recognized by
the pre sense front via a network of different
veh icle systems and can take steps to prepare
the vehicle occupants for a potentia l co llision.
The pre sense front wo rks with a radar sensor
and a video camera*.
It also functions within
the limits of the system when adaptive cruise
control* is switched off.

Audi pre sense basic
Description
Applies to vehicles : with Audi pre se nse basic
The function of the pre sense basic is activat­
ed at a speed of 20 mph (30 km/h) or higher.
The following functions can be triggered un­
der certain conditions within the limits of the
system:
- T ensioning of the safety be lts (for example,
during heavy braking) : The front safety belts
have reversible belt pretensioners. If a colli­
s ion does not occur, the safety belts loosen
slight ly and are ready to trigger again .
- Closing the windows (for example, if under­
or oversteering): The windows close until
there is only a small gap open.
Audi pre sense 95
Audi drive select: The dep loyment time is
adapted in dynamic mode.
A WARNING
The pre sense basic cannot overcome natu­ ral physical laws. It is a system designed to
assist and it cannot prevent a collis ion. Do
not let the increased safety provided
tempt you into taking risks. This could in­
crease your r isk of a collis ion.
- The system can deploy incorrectly due to
system-specific limits.
(D Tips
- Certa in pre sense bas ic functions switch
off when ESC is switched off (sport
mode) or when dr iving in reverse.
- The pre sense basic functions may not be
available if there is a ma lfunction in the
ESC system or the airbag control mod­
ule.
- Note that with pre sense bas ic, the rever­
sible safety belt pretensioner on the
front passenger's side deactivates when
t he fron t passenger's airbag is deactivat­
ed.
Audi pre sense front
Description
Applies to vehicles : wit h Audi pre sense front or Audi
adaptive crui se con trol
Pre sense front informs you if the distance to
the vehicle ahead falls below the safe distance
for an extended period of time. It can warn of
a possible collision and initiate braking ma­ neuvers, within the limits of the system.
When detected in time, the system can assess
dangerous situat ions where an object ahead
brakes suddenly or if your own veh icle is trav­
el ing at a high speed and approaching an ob ­
ject that is moving more slow ly . If detection is
not poss ible, then pre sense front does not re­
act.

Warnings
App lies to vehicles: with Audi pre sense front or Audi
adaptive cruise control
Fig. 94 Instrument cluster: approac h warning
The system recognizes various dangerous sit­
uations:
- Vehicles with adaptive cruise control : The
distance warning occurs if you drive too
closely to the object ahead for a long period
of t ime. If the object ahead brakes strongly,
you would not be able to avoid a coll ision.
The indicator light . indicates this.
- The
approach warning occurs when an ob­
ject ahead is traveling mo re slowly or brakes
strongly. When this warning occurs, it may only be possible to avoid a collision by
swerving or braking strongly. The message
Audi pre sense. Distance ¢ fig . 94 and a
warning tone will warn you about the dan­ ger. For vehicles with adaptive cruise con­
trol, the. indicator light also turns on.
If you do not react enough or not at all to a
dangerous situation that was detected by the
system, pre sense front provides ass istance by
applying the brakes.
- If a collision is imminent, the system will
first provide an
acute warning by braking
sharply. You will also be made aware of the
danger by the instrument cluster display
¢
fig. 94. F or vehicles with adaptive cruise
control, the. indicator light also turns on.
- If you do not react to the acute warning, pre
sense front can brake with increasing force

lision. The message Audi pre sense -Input
also appears.
- At low driving speeds , pre sense front can
begin complete deceleration shortly before
a collision
ll .
- If pre sense front determines that you are
not braking strongly enough when a colli ­
sion is immin ent, it can increas e the braking
force.
A WARNING
- Pre sense front cannot overcome natural
physical laws. It is a system designed to
assist and it cannot prevent a collision .
The driver must always intervene. The
driver is always responsible for braking
at the correct time. Do not let the in­
creased safety provided tempt you into
taking risks. This could increase your risk
of a collision.
- The system can deploy incorrectly due to
system-specific limits .
- Please note that the sensor does not al­
ways 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 vehicle's path or are difficult to de­
tect ¢
page 87, General Information.
-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,
other 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 responsible for braking at the
right time.
- Always pay attention to traffic, even
when pre sense front is switched on. Al-
ways be ready to intervene and take over
complete control of the vehicle whenever

Audi active Lane assist Lane assist
Description
Applies to vehicles: with Audi active lane assist
Active lane assist detects lane marker lines
within the limits of the system using a camera
in the windshield.
If you are approaching a de­
tected lane marker line and it appears likely
that you will leave the lane, the system will
warn you with corrective steering. You can
override this steering at any time. If you pass
over a line, the steering wheel will vibrate
lightly. In order for this warning vibration 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 vehicle.
The system will not warn you before crossing
a lane marker line if you have activated the
turn signal. In this case, it assumes that you
are changing lanes intent ionally.
The system is designed for driving on express ­
ways and highways and therefore only acti­
vates at speeds above approximately 40 mph (65 km/h).
_& WARNING
- The system warns the driver that the ve­
hicle 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.
Always keep your hands on the steering
wheel.
- Corrective steering may not occur in cer­
tain situations, such as during heavy
braking.
- There may be cases where the camera
does not recognize all lane marker lines.
Corrective steering can only take place
on the side of the vehicle where lane
marker lines are detected.
,....,
..,., 1) This function is not available in all countries. ,....,
Audi active lane assist 99
-Other road structures or objects could
possibly be identified unintentionally as
lane marker lines. As a result, corrective
steering may be unexpected or may not
occur.
- The camera view can be restricted, for
example by vehicles driving ahead or by
rain, snow, heavy spray light shining into
the camera or by dirt on the window. This
can result in active lane assist not detect­
ing the lane marker lines or detecting
them incorrectly.
- In certain situations where visibility is
low, the vehicle may switch from "early"
to "late" corrective steering
l).
-Under certain conditions such as ruts in
the road, an inclined roadway or cross­
winds, the corrective steering alone may
not be enough to keep the vehicle in the
middle of the lane.
- For safety reasons, active lane 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 con­
ditions may increase the risk of a crash.

Audi drive select Driving settings
Introduction
Applies to vehicles: with Audi drive select
Audi drive select makes it possible to experi­
ence diffe rent types of vehicle settings in one
vehicle. The driver can select from three
com­
fort , auto
and dynamic modes using the 1:1:.~
button in the center conso le or the MM I to
switch between a sporty and a comfortable
driving mode, for examp le. In the
individual *
mode, the settings can be adjusted to your
personal preferences. This makes it poss ible
to combine settings such as a sporty eng ine
tuning with light steering.
A WARNING
Using Audi drive select incorrectly can lead
to collisions, other accidents and serious injuries.
Description
Applies to vehicles: with Audi drive select
The vehicle setup in each mode depends on
the vehicle's features. However, the engine
and steering are always affected .
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 acce lerator
pedal movements.
Adaptive dampers (Audi magnetic ride)*
The adaptive dampers use senso rs to record
information regarding steering movements,
brak ing and acce lerat ion operat ions by the
driver, road surface, driving speed, and load.
With Audi drive se lect you can adjust the
adaptive dampers sporty (dynamic), comfort­
ab le (comfort) or balanced (auto).
Steering
The stee ring adapts in terms of stee ring assis­
tance. There are different modes
¢page 108.
Indirect steering that moves easi ly as in com -
Audi drive select 107
fort mode is especially suited to long drives
on a highway. The dynamic mode provides
sporty, direct steer ing.
For vehicles wi th progressive steering* the
steering performance is mo re agile.
Cornering light*
The cornering light adjusts when driv ing on
curves at speeds between 6 mph (10 km/h)
and 68 mph (110 km/h). The pivoting action
and the lighting are also adapted to the
mode.
Adaptive cruise control*
T he behav ior when accelerating can be adjust­
ed from comfortable to sporty, depending on
the Aud i drive select mode. Adapt ive cru ise
control also responds to the driving behavior
of the vehicle ahead in a more conservative or
sporty manner.
(D Tips
In some mode ls, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
