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.

Electronic stabilization
control (ESC)
Description
Elect ronic stabilization control (ESC) supports
driver safety.
It red uces the risk of slipping and
improves driving stability. ESC detects crit ica l sit­
uations such as when the vehicle is oversteering
and understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or reducing eng ine torq ue. When the ESC engages,
the hJ ind icator light blinks in the instrument
cluste r.
The fo llow ing systems are integrated in the ESC:
Ant i-loc k bra king system (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It increases braking power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the b rake pedal
until the dangerous situat io n is over . In veh icles
with adapt ive cr uise control*, the bra ke assist
sys tem is more sensitive if the d ista nce detec ted
t o the vehicle dr iv ing ahead is too small.
Anti -Slip Regulation (ASR )
ASR reduces eng ine power when the drive wheels
begin sp inning a nd adapts the force to the road
conditions . This makes it easie r to start, acceler­
a te and dr ive up h ills.
Electron ic differenti al lock (EDL )
The EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
other driving wheel or wheels ( if the veh icle is
eq uipped w ith all whee l dr ive*) . T his function is
not available at higher speeds.
146 In extreme cases,
ED L automat ically switches off
to keep the brake on the braked wheel from over­ heating. The veh icle is still working correct ly. ED L
will switch on again automatically when condi­
tions have returned to normal.
Steering r ecommendat ion
The ESC he lps to stabilize the vehicle by changing
the steering torque.
In veh icles with dynamic s teer ing*, ESC a lso
helps to stab ilize the steering in cr it ica l situa ­
tions.
Selective wheel torque control
Se lective whee l torque cont rol is used when d riv­
i ng on curves. The front whee l on the inside of
t h e curve or both whee ls on the i nside of the
curve are braked se lectively as needed. This al­
l ows more precise driving in curves.
Automatic post -collision b raking system
The "automat ic post-collis io n braking system"
can help to reduce the risk of sliding and of addi­
tiona l collisions after an acc ident. If the a irbag
contro l modu le detects a collision, the ve hicle is
braked by the ESC.
The veh icle does not bra ke automatically if:
-the dr iver presses the accelerator pedal, or
-the ESC, the brake system or the veh icle electri-
cal system are not functioning.
&_ WARNING
-The ESC and its integrated systems cannot overcome the lim its imposed by natura l
phys ica l laws. This is espec ially important
on sl ippery or wet roads. If the systems be­
gin acting to stabilize your vehicle, you
should immediately alter your speed to match the road and traffic conditions. Do
not let the increased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
-Please note the r isk of a coll is ion increases
when dr iv ing fast, especially through curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead . The ESC and
its integrated systems cannot always

Intelligent Technology
& WARNING
- Only apply the brakes for the purpose of
cleaning the brake system whe n road and
t raffic conditions perm it . You must not en­
dange r othe r road users . This increases the
risk of an accide nt.
- Never let the vehicle roll while the e ng ine is
stopped because this increases the risk of a n
a cci den t.
([) Note
- Neve r let the brakes " rub" by pressing the
pedal lightly when braki ng is not actually
necessa ry . T his ca uses the bra kes to over­
h ea t an d inc reases br akin g d istance an d

- B efo re driv ing downhill a long distance on a
steep hi ll, decre ase your spee d an d se lec t a

you nee d to b rake additionally, b rake in in­
tervals and not continuously .
(D Tips
- If the brake booste r is no t working, yo u
must press the brake pedal with much more
fo rce than normal.
- If you retrofit you r vehicle with a front spoil­
er, whee l covers o r similar items, ma ke sure
that the a ir flow to the front whee ls is not
