If the G1 indicator lamp illuminates, the sys­
tem has switched the ESC off. In this case , you
can switch the ignition off and then on to
sw itch the ESC on again . The system is func­
tioning completely when the indicator lamp
switches off .
I f the

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.

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need
less traction, you can switch
off ASR by press­
i ng the button~~
page 186, fig. 159 or
~ page 186, fig. 160. Be sure to sw itch ASR
on again when you no longer need less trac­
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle .
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r­
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 185
tomat ica lly when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-whee l dr ive) opera tes when dr iv­
ing thro ugh curves. The front wheel on the in­
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti­
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
function cannot overcome the laws of
physics. This is especially important on
slippery or wet roads . If the systems be­
gin acting to stabilize your vehicle, you
should immediately change yo ur speed
to match the road and traff ic conditions.
Do not let the increased safety provided
by these systems tempt you to take risks .
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per­
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los­
ing con tro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se­
lective whee l torque control* function
cannot prevent collisions.
