Introduction
Applies to vehicles: with S tronic transmiss ion
Your vehicle is equipped with an electronical­
l y -controlled DSG transmission called S tronic.
T wo independent clutches transfer the power
between the engine and transmission. It al­
lows the vehicle to accelerate without a no­
ticeable interruption in traction .
T he transmission upshifts or downshifts auto­
matically. The driving style continuously influ­
ences the selection of the driving program .
When a
moderate driving style is used, the
transmission selects the most econom ica l
driving mode. The transmission upshifts at a
lower RPM and downshifts at a higher RPM to
improve fuel effic iency .
T he transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) r=> page 114,

Fo r exa mple, the a irbag may depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld seats listed
<!> page 172), or
- a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
P ASS ENGER AIR B AG OFF light comes on in
the instrument cluster and stays on.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criter ia to reduce
the r isk of injury through interaction with the
airbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
r::> page 15 7, PASSENGER AIR BAG OFF light.
Always remember, a chi ld seat or infant carri­
er insta lled on the front seat may be struck
and knocked out of position by the rapidly in­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the child restraint and even se­
riously injure the child during inflat ion.
For this reason, and because the back seat is
the safest place for children -when properly
restrained according to their age and size - we
strongly recommend that children always sit in the back seat
r::> page 170, Child Safety .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System .
- T he inflating airbag will hit the child seat
or infant carrier with great force and wi ll
smash the child seat and child against
the backrest, center armrest, door or roof.
- Always install rear-facing child seats on
the rear seat.
- If you must install a rearward facing
child seat on the front passenger seat
-

because of exceptional circumstances
and the
PA SSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately install the rear-fac ing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your A udi dealer.
- Forward-facing child seats installed on the front passenger's seat may interfere
with the dep loyment of the a irbag and
cause serious persona l injury to the
child.
A WARNING
If, in except iona l circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always ma ke s ure the forward-facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never put the forward-facing child re­
straint up against or very near the instru ­
ment panel.
- Always move the passenge r seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible before installing
the forward-fac ing ch ild restra int. The
backrest must be adjusted to an upright
position.
- Make sure that the

Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
A irbag System in it . These parts include the
capacitive passenger de tect ion system, wir­
ing, b ra ck ets, and more. The cont ro l unit
monitors the system on the front passenger
seat when the ign ition is switched on and
turns the airbag indicato r light on when a
malfunction in the one of the system compo­
nents is detected¢
page 157 . Because the
fro nt passenger seat contains important parts
of the Advanced Airbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Ad­
vanced A irbag System for the front passenger
se at from doing i ts job in a c rash.
The front Advanced Airbag System
consists of the following:
- Crash sensors in the fro nt of the ve hicle that
m easure ve hicle accelera tion/de celera tion
to provide info rmation to the Advanced Air­
bag System abo ut the seve rity of the crash.
- An electronic cont ro l u nit, with integrated
c rash sensors for front and side impacts.
The cont ro l unit "decides" whether to fire
the front airbags based on the information received from the crash sensors. The contro l unit also "decides" whether the sa
fety belt
pretensioners sho uld be activated.
- An Advanced A irbag w ith gas generato r for
the driver inside the steering wheel h ub.
- An Advance d Airbag w ith g as generato r in­
side the inst rument panel for the front pas ­
senger.
- A capacit ive passenger detection system un­
de rneath the front passenger seat cover .
This system meas ures the electrical capac i­
tance of the person in the seat. The informa ­
tion registered is sent cont inuo usly to the
electronic control un it to regu late deploy­
ment of the front Advanced A irbag on the
passe nger side .
- An airbag monitor ing system and indicator
light in the instrument cluster¢
page 156 .
-A sensor in each front seat registers the dis­
tance betwee n the respective seat and the
steer ing whee l o r inst rument panel. The in­
formation registered is sent cont inuous ly to
t he ele ct ron ic contro l unit to regula te de­
p loyment of the front Adva nced A irb ags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of t he instr u­
ment p anel ¢
page 217 and t ells yo u when
the fron t Advanced Airbag on the passenge r
side has been turned off.
- A sensor in the safety be lt latch for the driv ­
er and for the front seat passenger that
senses whether t hat safety belt is latched or
not and transmits this information to the
electronic control un it.
A WARNING
Damage to the front passenger seat can
prevent the front airbag from wor king
p roperly.
- Improper repair or d isassembly of the
front passenge r and dr iver sea t will pre­
vent the Advanced Airbag System from

caused by airbags when they inflate, particu ­
l ar ly when the occupant sitting next to it is
not seated proper ly. The s ide a irbag for the
front passenger seat can be used with proper­ ly installed child restraints. Please be sure to
read the important information and warnings
wheneve r us ing a ch ild restrai nt in a vehicle:
Safety belts~
page 135, Airbag system
~ page 144, Child safety ~ page 170.
The si de ai rbag system ba sically con sists of:
- the e lectronic control module and external
s ide impact sensors
- the two airbags located in the sides of the
front backrests and the two airbags* located
in the rear backrest
- the airbag warning light in the instrument
cluster.
The airbag system is monitored elect ronica lly
to make certain that it is functioning properly
at all times . Each time you switch on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics).
T he side airbag system supplements the safe­
ty belts and can help to reduce t he risk of in­
jury to the driver's, front and rear passenger 's
upper torso on the side of the vehicle that is
struck in a side collision . The airbag deploys
only in s ide impacts and o nly when the veh icle
acceleration registered by the control un it is
h igh enough . If this rate is below the refer­
ence va lue programmed into the control u nit,
the side airbags will not be triggered , even
though the ca r may be badly damaged as a re ­
sult of the collision . It is not possible to de­
f ine an a irbag tr igger ing range that will cover
every possible angle of impact, since the cir­
cumstances will vary considerably between
one co llision and another . Important factors
include, for examp le, the nature (hard or soft)
of the impacting object, the ang le of impact ,
ve hicl e speed, etc.
~ page 165, Impor tant
safety instructions on the side airbag system.
Aside from the ir normal safety function, safe­
ty belts work to he lp keep the driver or front
passenger in position in the event of a side collision so that the side airbags can provide
protection.
T he airbag system is
not a substi tute for you r
sa fety belt . Rather, it is part o f the overa ll oc­
c u pant restra int system in you r vehicle . A l­
ways remember that the side airbag system can only help to protect you if you are wearing
your safety belt and wearing it proper ly. This
is another reason why you should always wear
your safety belts, not just because the law re ­
quires you to do so~
page 135, General
notes.
I t is important to remember that w hile the
supplementa l side airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injur ies, for example, swelling, bru is ing ,
fr iction burns and m ino r abrasions can a lso be
associated w ith dep loyed side airbags. Re­
member too, side a irbags w ill dep loy on ly
once and on ly in ce rtain kinds of accidents -
your safety belts a re always the re to offer pro­
tection .
Vehicle damage , repair costs or even the lack
of ve hicle damage are not necessarily an indi ­
cation of over-sensitive or failed airbag activa­
t ion. In some coll is ions, both front and side
airbags may inflate. Remember too, that air­
bags will deploy only once and only in certain
k inds of collisions -your safety belts are a l­
ways the re to offer p rotection in those acc i­
dents in which airbags are not supposed to
deploy or when they have a lready deployed .
The side airbag system will not deploy:
-when the ignit ion is switched off
- in side co llisions when the acceleration
measured by t he senso r is too low
- in front-end collisions
- in rear-end co llisions
- in rollove rs .
In some types of accidents the front airbags,
s ide cu rtain airbags and s ide a irbags may be
t rigge red togethe r.

Smart Technology
Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is installed by some vehi­
cle manufacturers to record data about crash­
es so that it can be analy zed later . Crash data
recorders are also called "Event Data Record­
ers ( EDR)" .
In some legal jurisdictions, it is not permitted
to access or download data recorded by pre­
installed crash data recorders in order to eval­
uate a crash without clear consent of the vehi ­
cle owner .
Your vehicle is not equipped with a crash data recorder. However it does contain a variety of
electronic control modules for various vehicle
systems such as engine function, exhaust
treatment or airbags and safety belts .
These electronic control modules record vehi­ cle data during normal driving for diagnosis
and repair purposes . The recording capability
of the electronic control modules is limited to
data only- no sound is recorded.
If the control
module detects a system ma lfunction or other
change in status, a very limited amount of da ­
ta is recorded for an extremely small period of
time . Data that is recorded in such a case may
include vehicle speed, d riving direction, the
load on the brakes and head restraints and
performance in the event of an acciden t or
other change in status . The stored data can
only be read or downloaded with special devi­
ces.
Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) con­
tr ibutes to driver safety. It reduces the risk of
slipp ing and improves driving stability. ESC
Smart Technolog y 189
detects critical situations such as the vehicle
oversteering and understeering or the wheels
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torque.
Once the ESC is activated, the indicator light
m blinks in the instrument cluster .
The following systems are integrated in the
ESC:
Anti-lock braking system (ABS )
ABS prevents the whee ls from locking when
braking. 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 peda l indicates that the
system is acting to stabilize the vehicle.
Brake assi st sys tem
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the brake pedal until the dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sensit ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin spinning and adapts the force to
the road conditions . This makes it easier to
start , accelerate and dr ive up inclines .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equ ipped with
all wheel drive*). This function is not available
at higher speeds .
In extreme cases, EDL automatically switches
off to keep the brake on the braked wheel
from overheating . The vehicle is still working
correctly. EDL will switch on aga in automat i­
cally when cond itions have returned to nor-
mal. .,..

Selective catalytic reduction
General information
Applies to vehicles: with diesel e ngine
In vehicles with se lective cata lytic reduction, a
urea solut ion (Ad Blue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen -emissions .
Ad Blue is the marketing name for Diese l Ex­
ha ust Fluid (DEF) .
The AdBlue is carried in a separa te tank in t he
vehicle . The AdBl ue usage accounts for ap­
proximately 0.5% to 1.2% of the diese l fuel
that is used .
When a message abo ut refil ling the Ad Blue
appears in the inst rume nt cl uste r dis play, you
must refi ll the Ad B lue yourse lf or have it refil­
l ed by an authorized Audi dealer or aut horized

A WARNING
Failure to heed Ad Blue refill information in
the inst rume nt cluste r can p revent the
ve­
hicle from being started and driven . If the
veh icle cannot be driven and an eme rgency
ar ises, perso na l inju ry can occur.
- Always have the Ad Blue tank refilled well
before the tank r uns d ry.
