Audi drive select Driving settings
Introduction
App lies to vehicles: w it h drive se lect
Audi drive select provides the possibility to ex­
perience different types of veh icle sett ings in
one vehicle. For instance, using the three
Comfort, Auto and Dynamic modes, the driv­
er can switch from a sporty to a comfortab le
driving mode with the press of a button.
Addit ionally, in vehicles with MM I*, the vehi ­
cle setup for
Individual* mode can be cus­
tomized by you. This makes it possib le to
combine settings such as a sporty engine tun­
ing with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury.
Description
Ap plies to vehicles: w it h drive se lect
The vehicle setup in each mode depends on
the vehicle's features. However, the engine,
automatic t ransmission* and steering are al­
ways involved.
.
Engine and automatic transmission*
Depending on the mode, the engine and the
automatic transmission respond quicker or in
a more ba lanced manner to acce lerator pedal
movements. In the sporty dynamic mode, the
automatic transmission shifts at higher R PMs.
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect steer ing that
moves easily, like the stee ring in comfort
mode, is best su ited to long dr ives on a high­
way. In contrast, dynamic mode prov ides
sporty, di rect steering .
The follow ing applies to vehicles with dynam ic
steer ing*: the stee ring ratio changes based on
ve hicl e speed in order to maintain optimum
Audi drive select 111
steering effort for the driver at all times. This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steer ing
is more direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuveri ng the vehicle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive steering pe rformance.
Adaptive dampers*
The adaptive dampers* use sensors to record
i nformation regarding steering movements,
braking and acceleration operations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the driving situation virtually i n rea l time.
Audi drive select also makes it possible to sat­
isfy the desire for sporty s uspension (Dynam­
ic) and comfortable suspension (Comfort)
without giv ing up balanced tuning (Auto).
Sport differential*
As a component of the all whee l dr ive system
(quattro ®)
q page 189, the sport differential*
distributes the driving power to the rear axle
depending on the situation . The distribution
of power var ies depending on the mode se­
lected. The goal is a high level of agility and
ability to accelerate on curves . The ve hicle is
very respons ive to steering .
Adaptive cruise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise control
also responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner .
Engine sound*
The sound of the eng ine is adapted to the se­
lected mode and ranges from subtle to sporty.
0) Tips
-In some models, the maximum vehicle
speed can only be reached in the
Auto
and Dynamic modes.

186 Intelligent technology
-Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways help to reduce the risk of loss of ve­ hicle control.
(i_) Tips
- ABS and ASR only work correctly when
all four wheels are equipped with identi­
cal tires . Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working .
- If the indicator light
I] or l;S (USA
models);tl] (Canada models) appears,
there may be a malfunction ¢

Turning off ASR
In some situations, it may be useful to switch
ASR
off to allow the wheels to spin. For exam­
ple:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow chains
Qu ickly press the
i.i, OFF I button ¢ fig. 159
and¢ fig. 160. The fi indicator light turns on
and the message

It is only possible to turn off the ASR up to
30 mph (SO km/h) for vehicles with front
wheel drive . At about 45 mph (70 km/h) it au ­
tomatically turns on again .
It is possible to
turn
off the ASR at any speed for vehicles with
all wheel drive.
Turning off ESC
Press and hold the I B OFFI button for three
seconds . The
Ii ESC indicator light turns on
and the message
Stabilization control (ESC):
off. Warning! Restricted stability
appears in
the display. ASR is also switched
off when ESC
is switched off.
Switching on
Press the 1 .$ OFFI button again. The 11 indica­
tor light turns on and the message
Stabiliza­
tion control (ESC): On
appears in the display .
_&. WARNING
- Drive wheels can spin and you can lose
control of the vehicle more easily when
ASR and ESC are switched off, especially
when the road is slippery .
- Switch ASR/ESC
off only when your driv­
ing skills, traffic and weather conditions
permit.
(D Tips
You cannot switch ASR and ESC
off when
