Automatic
transmission S tronic-transmission
Introduction
Appl ies to vehicles: with S tro nic tr ansmiss ion
Your vehicle is equipped with an electronical­
ly-controlled DSG transmission called S tronic.
Two independent clutches transfer the power
between the engine and transmission. It al­
lows the vehicle to accelerate without a no­
ticeable interruption in traction .
The 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 economica l
driving mode. The transmission upshifts at a
lower RPM and downshifts at a higher RPM to
improve fuel efficiency.
The 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) o page 115,

Child restraints on the front seat - some
important things to know
~ Be sure to read the impo rtant informat ion
and heed the WARNINGS for impo rtant de­
ta ils about ch ild ren and Advanced Airbags
Qpage 169.
Even though you r vehicle is equ ipped with an
Advanced Airbag Sys tem, ma ke certain that
all c hildren, especially those 12 years and
younger, a lways ride in the back sea t properly
restrained for their age and size . The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to ride.
The front seat is not the safest place for a
child in a forward-facing child seat. It can be a
ve ry dangerous p lace for an infant or a ch ild in
a rearward-facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comply with the require­
ments of United States Federa l Motor Ve hicle
Safety Standard 208 as applicable at the time
your ve hicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turned off ("sup ­
p ressed") if a c hild up to about one year of
age restra ined in one of the rear-facing o r fo r­
ward -facing infan t restra ints listed in Federal
M otor Vehicle Safety Standard 208 with w hich
the Advanced A irbag System in your vehicle
was certified has been installed on the front
passenger seat. Fo r a listing of the child re­
straints that were used to certify compliance

The PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced Airbag on the passenger side has been turned off by the e lectronic control unit. E
ach time you switch on the ignition, the
PAS­
SENGER AIR BAG O FF
light will come on for a
f ew seconds and :
- w ill stay on if the fro nt passenge r seat is not
occupied,
- w ill stay on i f the e lec tric al ca pacit ance
meas ured by the capacitive passenger de ­
tection system for the front passenger seat equa ls the combined capacitance of an in ­
fant up to about one year of age and one of
the rearward-facing or forward-fac ing ch ild
restraints listed in Federal Motor Vehicle
Safety Standard 208 with wh ich the Ad ­
vanced Airbag System in your vehicle was
c e rt ified . Fo r a listing of t he chi ld restraints
t ha t were used to certify you r vehi cle's com­
p lian ce w it h t he U.S. Safety Stand ard

cupied by an adult as regis tered by the ca ­
pacitive passenge r de tection sys tem
c::> page 158, Monitoring the Advanced Air·
bag System.
The PASSENGER AIR BAG OFF light comes on
when e lec trica l capacitance registered on the
front passenger seat is eq ua l to or less tha n
t h e comb ined capacitance of a typica l 1 year­
o ld infant and one of the rearward-facing or
forward-facing chi ld restraints listed in Fede r­
al Motor Vehicle Safety Standard 208 w ith
wh ich the Advanced Airbag System in your ve­
hicle was certified.
If the total e lectr ica l capacitance registered
on the front passenger seat is more than that
of a typical 1 year -o ld child but less than the
weight of a small adu lt , the front airbag on
t h e passenger side can deploy (the
PASSEN­
GER AIR BAG OFF
light does not come on).
If the
PASSENGER AIR BAG OFF light does
not come on, the front airbag on the passen­
ger side has not been turned off by t he e lec­
t ro nic cont ro l unit a nd can deploy if the con­
t ro l u nit se nses an impact tha t mee ts the con-
di tions s tored in its memory .

Fo r exa mple, the airbag 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 171), 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 159, 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 169, 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
-
A irbag system 149
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
rearmost 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
PASSENGER AIR BAG
OFF
l ight comes on and stays on all the
time wheneve r the ig nit ion is switched
on.
A WARNING
To reduce the ri sk of ser ious injury, ma ke
sure that the
PASSENGER AIR BAG OFF
light wi ll be displayed whenever a child re ­
straint is insta lled on the front passenger
seat and the ignition is switched on.
- If the PASSENGER AIR BAG OF F light
does not stay on, perform the checks de­
scribed

154 Airbag sys te m
- Always make su re that t here is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a
person when it is not, or to signal that it
is occ upied by someone who is heavier
than the person actu ally s itting on the
sea t. The presence of additiona l obje cts
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes o n and stays on all the
t ime whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l o t of very important pa rts of the Advanced
A irbag System in it. These parts incl ude the
capacitive passenger detect ion sys tem, wir­
ing, brac kets, 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 indicator light on w hen a
malfunction i n the one of the system compo­
n ents is detected
c::;, page 159 . Because the
front passenge r seat contains important pa rts
of the Advanced Airbag System, you must
take ca re to pr even t it from be ing damaged.
Damage to the seat may preven t the Ad ­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front o f the veh icle that
measure ve hicle acceleration/dece leration
to provide information to the Advanced Air­ bag System abo ut the severity of the crash .
- An electronic co ntro l unit, with i ntegrated
c rash sensors for f ront and side impacts.
The cont ro l unit "decides" whether to fire t
he front a irbags based on the in format ion
received from the crash sensors. The contro l
un it also "decides" whether the sa fety belt
pretens ioners sho uld be activated.
- An Advanced Airbag with gas generator fo r
the dr iver inside the steering wheel hub.
- An Advanced Airbag with gas gene rator in­
side the inst rument panel for the front pas­
senger.
- A capacit ive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuous ly to the
elect ronic 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 t he i nstr ument cluster
¢ page 158.
-A senso r in each front seat registers the dis­
tanc e between the r espective seat and the
s teer ing whee l o r ins trumen t panel. The in­
form ation regis tered is sent cont inuo usly to
t he ele ct ron ic cont ro l unit to regula te de­
p loyment of the front Adv a need Ai rbags.
- The
PASSENGER AIR BAG OFF ligh t comes
on and stays on in the cen ter o f the instr u­
ment panel
c::;, page 214 and tells you when
the front Advanced Airbag on the passenger
side has been turned off.
- A sensor in t he safety be lt latch fo r th e d riv­
er and for the front seat passenger that
senses whether that safety belt is latched or not and transmits this information to t he
electronic control un it .
A WARNING
--
D amage to the fron t passenger seat can
p rev ent the fro nt airbag from wor king
prop erly.
- I mp rope r re pa ir or disassembly of the
fr ont passenge r and dr ive r sea t will pre­
ven t th e Adv anced Air bag System from
functioning p ro perly.
- Repairs to the front pa ssenge r seat must
be pe rformed by qualifie d and properly
trained workshop personnel.

or the lower parts of the body. Front airbags
supp lement the three-point safety belts only
in some frontal collisions in which the vehicle
dece leration is high enough to deploy the air­
bags.
F ront airbag s will no t deplo y:
- if the ignition is switched off when a crash
occurs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by
the a irbag system is less than the m inimum
threshold needed for airbag deployment as
registered by the electronic control unit.
The f ront pas seng er airbag al so will n ot
deploy:
- when the front passenger seat is not occu­
pied,
- when the electrical capac itance measured by
the capacitive passenger detect io n system
for the front passenger seat indicates that
the passenger side frontal airbag must be switched off by the electronic control unit
(the
P AS SENGER A IR BA G OFF light
c:> page 159 and how they work comes on
and stays on).
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the r isk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright posit ion,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located.
- Occupants who a re unbelted, out of posi­
t ion or too close to the airbag can be se­
riously injured by an airbag as it unfolds
with great force in the blink of an eye
c:> page 148 .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
-
A irbag system 157
seriously injured and can be killed if the
front airbag inflates -even w ith an Ad­
vanced A irbag System.
- The inflating airbag will hit the ch ild seat
or infant carrier with great force and will
smash the child seat and child against
the backrest, center armrest, door or
roof.
- Always install rear-fac ing ch ild seats on
the rear seat.
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the
P A SSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately insta ll the rear-fac ing child seat in a
rear seat ing position and have the airbag
system inspected by your A udi dealer.
A WARNING
r---------
O b j e cts between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
or by be ing pushed into you as the airbag
inflates.
- Never hold things in your hands or on
your lap when the veh icle is in use.
- Never transport items on or in the area
of the front passenger seat. Objects
could move into the area of the front air­ bags during braking or other sudden ma­
neuvers and become dangerous projec­
tiles that can cause ser ious personal in­
jury if the a irbags inflate.
- Never p lace or attach accesso ries o r oth­
er objects (such as cup holders, te le­
phone b rac kets, large, heavy or bulky ob ­
jects) on the doors, over o r near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those areas and yourself . These
objects could cause injury in a crash, es­ pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move into the area of the s ide a irbag or
the front a irbag during braking or in a

sudden maneuver . Objects near the
air bags can become projectiles and cause
injury, particularly when the s eat is re­
cli ned .
- Never place or transport objects on the
front passenger seat. Objects on the
front passenger seat could cause the ca­
pacitive senso r in the seat to s ignal to
airbag system that t he seat is occupied
by a person whe n it in fa ct is not, o r th at
the person on the sea t is he avie r than he
or s he actually is. The change in electric
capacitance because of such objects can
cause the passenger front airbag to be
t ur ned on when it sho uld be off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout ob jects on the seat .
- Always make sure that there is nothing
on the front passenge r seat that will
cause the capaci tiv e passenge r detection
system in the s eat to s ignal to the A irbag
System that t he seat is occupied by a
perso n when it is not, or to sign al that it
is occupied by someone who is heavier
than the person actually sitting on the
seat . The prese nce of an o bject co uld
cause the passenger front a irbag to be
t u rned on when it sho uld be off, or co uld
cause the airbag to work in a way that is
differe nt from the way it wou ld have
