Audi drive select (drive
settings)
Introduction
Drive select makes it possible to experience dif­
ferent types of vehicle settings in one vehicle .
The driver can se lect
Comfort , Auto and Dynamic
modes in the Inf ota inme nt system to switch be­
tween, for example, a sporty and a comfo rtable
driving mode .
I n the
Individual mode, the sett ings can be ad­
justed to your perso nal preferences. This makes
it poss ible to comb ine settings such as a spo rty
engine setting with light steering.
Description
The following systems, among other things, are
influenced by drive select:
Engine and automatic transmission
Depending on the mode , the engine and a uto­
mat ic tran smission respond more quickly or in a
mo re balanced manner to accelerator peda l
104 movements
. In the sporty dynamic mode, the
transmission shifts at higher speed ranges.
Adaptive air suspension*
The adaptive a ir suspens ion* is an electron ically­
controlled air suspension and damping system.
The adjustment depends on the driving mode se­
l ected, steering movements, the driver's braking
and acce leration, and as the road surface, vehicle
speed and load.
The vehicle ground clearance depends on the
mode selected and the speed . When you are in
the
auto mode, the highway setting is activated
when you drive above 75 mph (120 km/h) for
more than 30 seconds. The ground clearance is
i ncreased automatically if the speed drops below
44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especia lly
su ited to long drives on a highway. The dynamic
mode provides sporty, direct steering.
App lies to: vehicles wit h dynamic steer ing
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef ­
fort for the driver at all times. Th is sets the steer­
i ng to be less sensitive at h igher speeds in order
to provide improved veh icle control. At reduced
speeds, steering is more direct in o rder to keep
t h e steer ing effort as minimal as possible whe n
the driver is maneuvering the vehicle. At low and
average speeds, dynamic steering* additionally
provides more responsive steering performance.
Sport differential*
As a component of the all whee l dr ive system
(quattro)
~ page 123, the sport differe ntial dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies from ba lanced (comfort) to sporty
(dynamic) depending on the se lected mode. The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.

" N .... 0 0 \,;J ' Intelligent Technology Electronic stabilization
control (ESC)
Description
Electronic stabilization control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critica l sit­
uations such as the vehicle oversteering and un­
dersteering or the wheels are spinning. The vehi­
cle is stabilized by applying the brakes or reduc­ ing engine torque. As soon as the ESC is actively
regulating, the
If] indicator light b links in the in­
strument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is act ing to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat ion is over . In veh icles
with adaptive cruise contro l*, the brake assist
system is more sensitive if the distance detected
to the vehicle dr iv ing ahead is too small. On
vehicles with activated and functioning night vi­
sion assist*, the brake assist system can respond more sensitively if there is a warning .
Anti-Slip Regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL applies the brakes to a whee l that starts
spinning and transfers the drive power to the
other driving wheel or wheels (if the vehicle is
Intelligent Technology
equipped with a ll wheel drive*). This function is
not avai lab le at higher speeds.
In extreme cases , EDL automatically switches off
to keep t he brake on the braked whee l from over ­
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Power steering
The ESC can also support veh icle stability
through steering .
Selective wheel torque control
Selective wheel torque control is used when driv­
i ng on curves. The front whee l on the ins ide of
the curve or both wheels on the ins ide of the
curve are braked selectively as needed. This al­
lows more precise driving in curves.
Automatic post-collision braking system
The "automat ic post-collis ion braking system"
can help to reduce the risk of sliding and of addi­
tional collisions after an accident. If the airbag
contro l module
detects a co llision above a certa in
vehicle speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
cal system are not functioning.
A WARNING
-
- The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
p hys ica l laws. This is especially impo rtant
on slippery or wet roads. If the systems be­
g in acting to stabilize yo ur 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 risk of a coll ision increases
when dr iv ing fast, especially through curves
and on slippery or wet roads, and when

" N .... 0 0 \,;J ' All wheel drive (quattro)
Applies to: vehicles wit h all wheel drive
In oil wheel drive, oil four wheels ore powered .
General information
In all wheel drive, the driving power is divided be­
tween all four wheels. This happens automatical­
l y depending on your driving behavior as well as
the current road conditions. Also see
c:> page 119, Electronic stabilization control
(ESC) .
A center differential distributes the driving power
variab ly to the front and rear axle. It works to­
gether with selective wheel torque control, which
activates when driving through curves
c:>poge 119. With the sport differential*, power
distribution to the rear wheels is variable and can
be adjusted w ith drive select
c:> poge 104 .
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics
both under normal driv ing cond itions and on
snow and ice. Always read and fo llow safety pre­
cautions
c:> .&, .
Winter tires
By using all wheel drive, your vehicle has good
forward mot ion with standard tires in winter con­
ditions . However, in winter we recommend using
winter or all season tires on all four w heels, be­
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 217, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid using tires with different tread depths
c:> page 208, New tires or wheels .
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
Intelligent Technology
A WARNING
--
- Also, in veh icles with all wheel drive, adapt
your driving style to the current road and
traffic conditions . Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause t his increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydrop lane" if driving at speeds that
are too high. Unlik e front wheel drive
veh icles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty . This significantly improves the start ing ability
and increases the vehicle battery life.
(D Tips
- If you dr ive short distances frequently, the
veh icle battery may not charge enough
w hile driving. As a result, convenience func­
tions for electr ical equipment may be tem­
porarily unavailable.
- Th e vehicle battery w ill gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be reduced or
switched off.
