bars become red from the bottom upward.
A WARNING
If you press the ISE TI b utton when driving at
speeds below 20 mph (30 km/h), the vehicle

Assistance systems
Appl ies to: vehicles w ith Audi side assist
If you activate a turn signal when active lane as­
sist is ready and it classifies a lane change as crit­
ical because of vehicles traveling alongside you or
approaching you, there will be noticeable correc ­
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane .
Applies to: veh icles without Audi s ide ass ist
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 intentionally.
A WARNING
-The system warns the driver that the vehicle
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. Al­
ways keep your hands on the steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking.
- There may be cases where the camera does not recognize all lane marker lines . Correc­
tive steering can only take place on the side of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi­
bly 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 ex­
ample 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 detecting the
lane marker lines or detecting them incor­
rectly.
- Under certain conditions such as ruts in the
road, an inclined roadway or crosswinds, 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
134
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 .

If the system is switched on but is not ready to

the cause:
-There is no lane marker line.
-The relevant lane marker lines are not detected
(for example, mark ings in a construction zone
or because they are obstructed by snow, dirt,
water or lighting).
-The veh icle speed is below the activation speed
of approx imately 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.

Audi drive select
Introduction
App lies to : vehicles wi th Audi drive se lec t
Audi drive select makes it poss ible to experience
different types of vehicle settings in one vehicle.
The dr iver can select from three modes,
Comfort ,
Auto
and Dynamic , using the ~.'/:.1 button in the
center console or by using the Infotainment sys­
tem. This allo ws you to switch between a sporty
and a comfo rtable driving mode, for example. In
the
Individual* mode, the settings can be adjust ­
ed to your personal preferences . This makes it
possible to comb ine settings such as a sporty en­
gine setting with light steering.
Description
Applies to: vehicles wit h Audi drive se lect
The vehicle setup in each mode depends on the
vehicle 's features. However, the engine and
steering are a lways affected .

u. 00 .-< N l'­ N .-< 0 N > 00
Engine and automatic transmission
D epending on the mode, the eng ine 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 higher speed ranges.
Suspen sion control (Audi magnetic ride) *
The s uspension contro l uses sensors to reco rd in­
formation regarding steering movements, brak ­
ing and acce leration operations by the driver, as
well as information abo ut th e road s urface, driv ­
ing speed, and load. With Audi dr ive select you
can adjust the suspens ion control to sporty (dy­
namic), comfortable (comfort) or balanced (au­
to) .
Steering
T he steering adapts in terms of steering assis ­
tance. There are different modes
¢ page 142 .
Indirect steering that moves easily as in comfort
mode is especia lly su ited to long drives on a high ­
way . The dynam ic mode p rovides sporty, d irect
steer ing .
For vehicles w ith progressive steering* the steer­
in g performance is more ag ile .
Audi adapt ive light *
The i llumination on curves in adaptive light is
adapted to the se lected mode.
Audi adaptive cruise control*
The behav ior when a cce le ra ting can be adjus ted
from com fortab le to sporty, depending on the
drive select mode . Adaptive cr uise control a lso
r e sponds to the driving behavior of the ve hicle
ahead in a more conservative or sporty manner.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynam ic modes.
A ss istance systems
- The "S " sele ctor leve r position au tomatically
engages if the dynamic mode is selected.
