You can adjust individual settings in the MMI.
.. Select : I CARI funct ion button > Car systems
control button > Driver assist> Audi lane
assist .
Setting the warning point Early :
With this setting, a warning is provided
before a wheel touches the detected lane
boundary line. The warning depends on the
angle in which the ve hicle is approaching the
line. The distance at which the warning is giv­
e n increases as the angle becomes sharper. If
you dr ive toward a boundary line at a very
sha rp angle, the warning will come just before
a w heel touches the line.
Medium : With this sett ing, the warning point
i s adapted to the cou rse of the road, the lane
width and the speed . You wi ll st ill be warned
if you cross slightly over a dotted line when
driving on curves.
Late: This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel v ibration can be set to
Low , Medium or Strong . Selecting each of the
set tings will cause the steering wheel to vi­
brate so you can ch eck the strength of the vi­
bration in that setting.

examp le, you ca n combine settings such as a
sporty en gine t uning with comfortab le steer­
ing.
A WARNING
Improper use of the A udi drive select can
cause collisions, ot her acc idents and se ri­
ous pe rsonal injury.
Description
The vehicle setup in each mode depends on
the veh icl e's featu res. The engine, t ransm is­
sion, stee ring, reve rsible sa fe ty belt tension­
e rs a nd adap tive air su spension are alw ays in­
volved.
Engine and transmission
Depending on the mode, the e ng ine and the
tra nsmission respond quic ker or i n a more bal­
an ced manne r to acce le rator pedal move­
men ts. In the sporty dyn ami c mode, the
tra nsmission sh ifts at highe r RP Ms.
Air suspension
The adaptive air suspens ion/adaptive air sus­
pe nsion spor t*
(Air suspension in the MM I) is
an elec tronic ally con trolled air suspensio n and
da mpi ng sys tem. They are adjus ted depend­
ing on the se lected driving mode, the drive r's
steering, braking and acceleration input and
the road s urface, ve hicle speed and load. A
sporty setting is generally used i n ve hicles
with adaptive air suspension sport*. T
he vehicle clea rance varies depending on the
se lected mo de an d the speed .
T he highw ay setting is activate d automatically
whe n you dr ive above 7 5 mph (120 km/ h) for
more than
3 0 seconds in the auto or dynamic
mode. The gro und clea rance is increased a uto ­
matically if the speed drops below
44 mph
(70 km/h) for more than 120 seconds.
Steering
T he s teering adap ts i n t erms of s teer ing effor t
and stee ring ratios . Indirect stee ring that
moves easily, like the steer ing in comfo rt
mode, is best suited to long drives on a high­
way. In contrast, dynamic mode provides
sporty, direct steer ing .
The following app lies to vehi cles with dynamic
stee ring* : the steer ing rat io changes based on
vehicle speed in order to ma inta in optimum
steering effort for the drive r at all times. This
sets the stee ring to be less sens itive at h igher
s p eeds in order to provide improved vehicl e
control. At r educed speeds, howeve r, steer ing
is mo re dir ect i n order to keep the stee ring ef­
f o rt as minima l as po ssible when the drive r is
mane uveri ng the veh icle. At low and average
speeds, dynamic steering ad dit iona lly pro ­
vides more responsive steering pe rformance .
Sport differential*
As a compone nt o f the all whee l dr ive system
(quat tro)
r:!> page 204, the Spor t differen tia l*
dis tributes t he d riving power to the rear ax le
depen ding on the sit uat io n. The distrib ution
of power var ies depending on the se lected
mode, from ba lanced (comfort) to agile (dy­
nam ic). The goal is a high level of agility and
ability to accelerate on curves . The vehicle is
very res pons ive to stee ring .
Curve light*
The curve light adapts to driving on curves.
The pivoting act ion and the lighting are also
adapted to the mode.
Adaptive cruise control*
T he be hav ior when ac celera ting can be adjust­
ed from comforta ble to sporty, de pending on ..,.

the drive select mode. Adaptive cruise control
also responds to the driving behavior of the
veh icle ahead in a more conservative or sporty
manner.
Engine sound*
The sound of the engine is adapted to the se­
l ected mode and ranges from subtle to sporty.
(D Note
- Make sure there is enough clearance
above and below the vehicle when park­
i ng. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load cond i­
tions and changes to the dr iv ing modes,
which can affect clearance.
- When transporting the veh icle on a car
carrier, tra in, ship or by other means, on­
ly tie the veh icle down at the running
surface of the tires, which is the outer
circumference. Secur ing the vehicle at
the axle components, s uspension struts
or towing eyes is not permitted because
the pressure in the air suspension struts
can change during transport . The vehicle
may not be sec ured s ufficient ly if this
happens.
- If you are going to tow a trailer, you
must activate the trailer operation mode
C? poge 212.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the
auto
and dynamic modes.
- Selecting the
dynamic mode results in
sporty shifting characteristics . The S
gear position engages automatically.
- In vehicles that have dynamic steering*,
operating noise is heard when starting or
stopping the engine. Th is does not indi­
cate a problem.

Pedestrian de tect ion depends on the differ­
ence in temperat ure between the person and
the background. Pedestrians may not be de­
tected if the temperature difference is too
smal l. The pedestrian highlighting feature is
deactivated at temperatures above 77 °F (25
0 () and when it is light outside.
A WARNING
--
Night vision ass istant has l imits and can­
not always detect pedestrians . Always pay
close attention to traffic and the area
a round your vehicle even when night vision
assis tant is sw itched on.
- Night vision assistant can only warn
about people located within the v isual
range of the infrared camera. The vis ual
ra nge corresponds to the image in the in­
strument cluster display.
- Night vision assistant may not detec t
peop le and highlight them if
- they are not in an upright posit ion, for
example if they are sitt ing, crouching
o r lying down and/or
- if the outline in the disp lay is incom­
plete or interrupted, for example be­
cause the perso n is part ial ly hidden by
a parked vehicle.
@ Tips
- Pedestrian detection and the pedestrian
warm ing are limited to objects that are
detected as pedest rians. The system
does not detect an imals. Even though
the shape and warmth radiated by each objec t detected is eval uated, the system
does have limitat io ns and it can g ive in­
correct warnings .
- For technical reasons, the image pauses
