Assistance systems
Description
Applies to: vehicl es w ith Aud i drive select
The follow ing 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
mo re 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 regard ing steering movements ,
braking and acceleration operations by the driv­
er , road surface, driving 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
sporty
( Dynamic ), comfortab le ( Comfort ) or bal­
anced
( Auto ).
Steering
The power steering adapts. Indi rect s teer ing that
moves easily 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
steer ing effort for the driver at all times . This
sets the steering to be less sensitive at higher
speeds in order to prov ide improved vehicle con­
trol. At reduced speeds, steering is more direct in
order to keep the steering effort as min imal as
possible when the driver is maneuvering the vehi­
cle. At low and average speeds, dynamic steer­
ing* additionally provides more responsive steer­
ing performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 1 SO, the sport differential dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the selected mode
134
from moderate (Comfort ) to sporty (Dynamic ).
The goal is a high level of agility and ability to ac­
ce lerate on curves . The vehicle is very respons ive
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.
@ Tips
The S selector lever position automatically en­
gages when the
Dynamic mode is selected .
Selecting the driving mode
Applies to: vehicles with Audi drive se lect
Fig. 135 Center co nsole: controls for drive se lect
.,. Press the left or right a rrow key ~ fig. 135 until
the desired mode appears in the instrument
cluster/ Infotainment system disp lay. Or
.,. Select in the Infotainment system: IMENU j but-
ton
> Vehicle > Audi drive select.
.,. 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.
.,.

Parking systems

proaching an obstacle from approximately
3.1 feet (95 cm) away. There are audible signals
when approximately 1.6 feet (SO cm) away from
the obstacle.
If you press the P,,1A button to switch
the park ing aid off, it can only be reactivated au­
tomatically when one of the following conditions
is met :

-The vehicle speed exceeds 6 mph (10 km/h).
-The ignition is switched off and back on again.
-The parking brake is set and then released .
-The selector lever must be in the P posit ion (au-
tomatic transmission) .
Segments in the visual display
The segments in front of and behind the vehicle
q fig. 138 help you to determine the distance be­
tween your vehicle and an obstacle . The red
lines* mark the expected direction of travel ac­
cording to the steering angle. A white segment
i ndicates an identified obstacle that is outside of
the vehicl e's path. Red segments show identified
obstacles that are in your vehicle's path. As your
vehicle comes close r to the obstacle, the seg ­
ments move clos er to the vehicle. The collision
area has been reached when the next to last seg­
ment is displayed. Obstacles in the coll is ion area ,
i ncluding those outside of the vehicle's path, are
shown in red. Do not continue driving forward or
