Audi drive select (drive
settings)
Introduction
Drive select makes it possible to experience dif­
ferent types of vehicle settings in one vehicle.
The dr iver can select
Comfort , Au to a nd D ynamic
modes i n the Infota inment system to switch be­
tween , fo r example, a sporty and a comfo rtable
driving mode .
Sett ings can be ad justed to your personal p refe r­
e nces in
Ind ividual mode. Th is makes it poss ible
t o combine settings such as a sporty engine se t­
ting w ith light steering .
Description
The following systems, among other things, are
infl uenced by drive select :
Engine and automatic transmission
Depending on t he mode, the e ng in e and auto ­
mat ic transmission respond more q uick ly o r in a
more balanced manner to accelerator pedal
Assist
movements . In the sporty dynamic mode, the
transmission shifts at higher speed ranges.
Adapt ive a ir suspension *
The adapt ive ai r suspension* is an e lectron ically­
co ntro lled air suspens io n and dampi ng sys tem.
T he ad justmen t depends o n the dr iving mode se­
l ected, steering movements, the driver's braking
and acce le ration, and as the road surface, veh icle
speed and load.
T he vehicle groun d clearan ce depends on t he
mode selected and the speed . When you are in
the
auto , the highway setting is activated when
yo u drive above 75 mph (120 km/h) for more
than 30 seconds. The g round clearance is in­
creased automatically if the speed drops be low
44 mp h (70 km/h) for more than 120 seconds .
Suspension control*
With the Audi Dynamic Ride Control damping
contro l, dampening characteristics of the ve hicle
can be individually adjusted us ing drive select.
This makes it possible to satisfy the des ire for
sporty suspens ion
(DYNAMIC) and comfortable
s u spension (COMFOR T) without g iv ing up bal­
anced tu ning (AUTO) .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is espec ially
su ited to long drives on a highway . The Dynam ic
mode provides sporty, direct steering .
Applies to: vehicles with dynamic steering
The steering ratio changes based on veh icle
speed in order to maintain opt imum steer ing ef­
fort fo r th e driver at all times . Thi s sets the s teer­
i ng to be less sensitive at h igher speeds i n orde r
to provide improved ve hicl e con trol. At reduced
speeds, stee ring is more direct in orde r to keep
t h e s teer ing effort as minimal as possible when
t h e driver is maneuvering the ve hicle. At low and
average speeds, dynamic steering * additionally
provides more responsive steering performance.
Sport differential*
As a compone nt o f the all whee l dr ive system
(qua ttro)
~ page 124, the sport different ia l dis -
t ributes the driving power to the rear axle .,.
105

Ass is t
depending on the s ituation. The distr ibution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high leve l of agility and ability to accel­
erate on curves. The veh icle is very responsive to
steer ing .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivot ing action and the lighting also adapt to
the mode.
Adaptive c ru ise contr ol*
The behavior when acce le rating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control a lso
responds to the driving behavior of the veh icle
ahead in a more conservative or sporty manner.
Engine sound *
The engine sound adapts to the current mode
and can be subtle to sporty .
(D Note
Applies to: vehicles with adaptive air suspension
- Make sure there is enough clearance above
and below the veh icle when parking. The
height of the vehicle (ground clearance) can
change once it is parked due to tempera ture
fluctuations, changes to the load condit ions
and c hanges to the d riving modes.
- When transporting the veh icle on a car car­
r ier, tra in, ship or by other means, only tie
the veh icle dow n at the running surfa ce of
the tires, w hic h is the outer circ umference .
Securing the vehicle at the axle compo ­
nents, suspension st ruts or towing eyes is
not permitted because the pressure in the
air suspension struts can change dur ing
transport . The vehicle may not be secured
sufficiently if this happens.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynam ic modes.
106
- The S se lector lever position a utomat ica lly
engages if the dynamic mode is selected.
- Applies to: vehicles with dynamic steering:
operating noise is heard when starting or
stopp ing the engine. Th is does not indicate
a problem.
Selecting the driving mode
F ig. 116 Infota inmen t: drive select

improves dr iving stability. ESC detects crit ica l sit­
uations such as the veh icle oversteering and un­
dersteering or the wheels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
ing engine torque. As soon as the ESC is active ly
regulat ing, the
D.1 indicato r light blin ks in the in­
s trumen t clus ter.
The fo llow ing systems are integrated in the ESC :
Ant i-lock braking system (ABS)
ABS p revents the whee ls from locking whe n brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis­
tance . It increases brak ing power when the driver
presses the brake pedal q uick ly in emergency sit­
uations . You must press and hold t he b rake pedal
until the dangerous sit uat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle dr iv ing ahead is too small. On
ve hicl es with act ivated and f unct io ni ng night vi ­
sion assist*, the brake assist system can respond mo re sensit ively if there is a warning .
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive w heels
be gin sp inning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler ­
ate and dr ive up h ills.
Electronic differential lock (EDL)
E DL a ppl ies the bra kes to a wheel tha t st art s
sp inning and tra nsfe rs t he dr ive powe r to t he
120
other driving whee ls. This func tion is no t ava ila ­
ble at hig her speeds.
I n extreme cases , EDL automat ic al ly swi tches off
to keep t he b rake o n the br aked wheel from ove r­
heating. The ve hicle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze th e vehicle by ch ang ing
t h e s teer ing torque.
I n veh icles with dynamic s teer ing*, ESC a lso
helps to stab ilize the s teeri ng in cr it ic al situ a­
tions.
Selective wheel torque control
Se lective wheel to rque control is used when d riv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both whe els on the i nside of th e
cu rve are braked se lectively as needed. This al­
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "a utomat ic post -coll is io n braking system"
can help to reduce the risk of sl iding and of addi­
tiona l co llisions after an acc iden t. If the a irbag
c on tro l modu le dete cts a collision above a cer tain
vehicle speed, the veh icle is braked by t he ESC.
The veh icle does not brake automatically if:
- the drive r presses the accelerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle elect ri­
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. Th is is es pec ially i mpo rtan t
on s lippery or we t roads. If the system s be­
g in a cting to s tabili ze yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let the inc reased safety provided tempt

Intelligent Technology
necessary. This causes the brakes to over ­
heat and increases bra king distance and
causes wear .
- Befo re driving downhi ll a long distance on a
steep hill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, b rake in in­
t e rvals a nd not continuously .
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit you r vehicle with a front spoil­
e r, whee l covers o r similar items , make sure
that the a ir flow to t he fron t wheels is not
i nte rr u pted . Othe rw ise the brake sys tem
ca n become too hot .
