A WARNING
- If the fIE) (USA models)/ tl] (Canada mod­
els) warning light does not go out, or if it
comes on while dr iv ing, the ABS system is
not working proper ly . The vehicle can then
be stopped only with the standard brakes
(without ABS). You will not have the protec­
tion ABS provides. Contact your authorized
Audi dealer as soon as possible.
- USA models: If the 1111 warning light and
the
9 warning light come on together, the
rear wheels could lock up first under hard
braking. Rear wheel lock-up can cause loss
of vehicle control and an acc ident. Have your
veh icle repaired immediately by your au­
thorized Audi dealer or qualified workshop .
Drive slowly and avoid sudden, hard brake
applications .
-Canada models: If the brake warn ing light
• and the ABS warning light
tlJ come on
together, the rear whee ls could lock up first
under hard b raking. Rear whee l lock-up can
cause loss of vehicle control and an acci­
dent . Have your vehicle repaired immediate­
ly by your authorized Audi dea ler or quali­
fied workshop. Drive slowly and avoid sud­
den, hard brake applications.
t!i I !i: Safety systems
The fl (USA models)/ EI (Canada mode ls) indi­
cator light monitors the safety systems (e.g. a ir­
bags, pretensioners) and illum inates for a few
seconds each time you switch the ignition on.
If the
II (USA models) tEI (Canada models) in­
dicator light does not go out, or if it illuminates
wh ile you are driving, or if it starts to blink, then
there is a malfunct ion somewhere in the system .
If the light does not illuminate when you switch
the ignition on, this also means there is a mal­
function.
A WARNING ~

Audi drive select Drive settings
Introduction
Applies to: vehicles with Audi drive select
Drive select provides the possibility to experience
d iff erent types of vehicle settings in one veh icle.
F or instance, using the three
Comfort, Auto and
Dynamic modes, the driver 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 vehicle
setup for
Individual* mode can be customized by
you. This makes it possible to combine settings
such as a sporty engine tuning with comfortable
steering.
A WARNING
-
Improper use of the Audi drive select can
cause collisions, other accidents and serious
personal injury .
Description
Applie s to: vehicles with Audi drive select
The vehicle setup in each mode depends on the
veh icle's features . However, the engine, auto­
matic transmission and steering are always in­
volved.
Engine and automatic transmission
Depending on the mode, the engine and the au ­
tomatic transm ission respond quicker or in a
more balanced manner to accelerator pedal
movements . In the sporty dynam ic mode, the au­
tomatic transmission shifts at higher RPMs .
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steer ing that moves
eas ily, like the steering in comfort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering.
gi The follow ing applies to vehicles with dynam ic
;:::: steering*: the steering rat io changes based on
r--.
~ vehicle speed in order to ma inta in optim um 0
fi:' steering effort for the driver at all times. This 00
Audi drive select
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
tro l. At reduced speeds, however, steering is
more direct in order to keep the steering effort as
minimal as possible when the driver is maneuver­
ing the vehicle. At low and average speeds, dy ­
nam ic steering additionally prov ides more re­
sponsive steering performance .
Adaptive dampers*
The adaptive dampers* use sensors to record in­
formation regarding steering movements, brak­
ing and acceleration operations by the driver,
road surface, driving speed, and load . This makes
it possible to adapt damping to the driving situa­
t ion virtua lly in real time. Drive select also makes
it possible to sat isfy the desire for sporty suspen­
sion (Dynamic) and comfortable suspension
(Comfort) without giving up balanced tuning (Au­
to).
Sport differential*
As a component of the all whee l dr ive system
(quattro)
c::> page 172, the sport different ial* dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the mode selected.
The goal is a high level of ag ility and ability to ac­
celerate on curves. The vehicle is very responsive
to steering.
Audi adaptive cruise control*
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 sound of the engine is adapted to the select­
ed mode and ranges from subtle to sporty.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto and
Dynamic modes.
- For vehicles with an automatic transmis-
sion, se lecting the
Dynamic mode resu lts in ...,

Intelligent Technology Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road ho lding and vehicle
dynamics to help reduce the probability of skid­
ding and loss of vehicle control. It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situat ions, including when the
vehicle is beginn ing to spin (yaw) out of control
and helps you to get the veh icle back under con­
tro l by selectively braking the wheels , and/or re­
ducing engine powe r and provid ing steering as­
sistance to help ho ld the veh icle on the driver 's
intended course. The indicator light
bJ in the in­
strument cluster blinks when ESC is taking action
to help you contro l th e vehicl e.
The follow ing systems a re integr ated in the ESC:
Anti -lock braking system (ABS )
ABS preve nts the wheels from lock ing up when
b raking . The ve hicle can still be stee red even dur­
in g ha rd brak ing . Apply steady pressure to the
b rake pedal. Do not p ump the pedal. A pu lsing in
the brake pedal indicates tha t the system is help ­
ing you to brake the vehicle .
Brake assist system
The brake assist sys tem can dec rease braking dis­
tance .
It increases brak ing power when the d rive r
pr esses the brake pedal q uickly in eme rge ncy sit ­
uations . You m ust press and hold the b rake pedal
unti l the situation is over . In vehicles with adap ­
tive cruise control* , the brake assist system is
mo re sensitive if the distance det ected to the ve­
h icle ahead is too small.
Anti -slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and dr ive up h ills.
gi Electronic differential lock (EDL ) ...... N

Intellig ent Technology
whee l or wheels if the vehicle is equ ipped with
all-wheel drive*. This function is not avai lable at
highe r speeds.
In extreme cases , EDL automat ic all y swi tches off
to help keep t he b rake on the braked wheel from
overheating . EDL will switch on again automati­
ca lly when cond itions have returned to normal.
Steering recommendation
T he ES C helps to s tabilize the vehicle by changing
the s teering torque.
In veh icles with dynamic steer ing*, ESC a lso
helps to stab ilize the steer ing in crit ica l sit ua­
tions.
Electronic interaxle differenti al lock */
selective wheel torque control*
T he elect ronic inte raxle d iffere ntial lo ck (front
whee l dr ive) o r the sele ct ive whee l torque co ntro l
(a ll w heel d rive) operates when driving thro ugh
cu rves. The front wheel on the inside of the curve
o r both wheels on the inside of the curve are
braked selectively as needed. This allows more
precise driving in curves . The applicab le system
may not activate when driving in wet or snowy
condit ions .
A WARNING
--The ESC and i ts integrated systems ca nnot
overcome the laws of physics. This is espe­
cially importa nt on slippery or wet roads. If
the systems begin act ing to sta biliz e your
veh icle, you shou ld immedi ate ly change
your speed to match the road and traffic conditions. Do not let the increased safety
provided by these systems tempt yo u to
take risks. Doing so will increase the risk of
a loss of vehicle control, collision and seri­
ous personal injur ies .
- Always adapt your speed to road, traffic and
weather conditions . The risk of losing con ­
trol of the vehicle increases when driv ing
too fast, especially through curves and o n
slippe ry o r wet roads , and whe n driving too
close to ve hicl es up ahea d. The ESC and its
integ ra t ed systems cannot always preven t
collis ions -the re is s till a risk o f accidents!
