{D) Tips
Always replace child restraints that were in­
stalled in a vehicle dur ing a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Ai rbag System" in compliance with United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208 as applicable at the time your vehicle was manufactured.
The Advanced Airbag system in your vehi cle has
been certified to meet the "low-risk" require­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the
"s uppress io n " req uiremen ts of the Safety Stand­
ard, to turn of f the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in chi ld restraints that are listed in
the Standard.
E ven though your vehicle is equipped with an Ad­
vanced Ai rbag system, all children, especially
those 12 years and younger, should always r ide
in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a
Child safety
child to ride. The front seat is not the safest place
for a chi ld in a forward-facing chi ld safety seat . It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat.
T he vehicle's Advanced A irbag System has a ca­
pacitive passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a ch ild in a child restraint sys­
tem on this seat.
The capacitive passenger detection system regis­
ters the changes that result in an electrical field
when a child, a child restraint, and a baby b lanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a ch ild restraint, and a baby blanket on
the front passenger seat is related to the child
restraint system resting on the seat . Th e meas­
ur ed capacitance of a child restraint system var­
ies depending on the type of system and specific
make and mode l.
T he elect rical capacitance of the various types,
makes, and models of child restra in ts specified
by the U.S .National Highway Traff ic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w ith a typical 1 year -old infant, the Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detection
system with the data stored in the electronic con­
trol unit.
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Unit­
ed States Federal Motor Vehicle Safety Standards
and has been certified by its manufacturer for
use with an a irbag. Always be sure that the child
r estra int is properly installed at one of the rear
seating positions.
If in except ional circumstances
you must use it on the front passenger seat, care­
f ully read all of the information on child safety
and Advanced Airbags and heed all of the .,.

@ Tips
The chi ld seats listed in categories A to C have
been statically tested by Audi only for the Ad­
vanced Airbag function .
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the vehicle, especially children:
~ Always use the right child safety seat for each
child and a lways use it properly~
page 22 7.
~ Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe­
ty seat .
~ When using the vehicle safety be lt to install a
child safety seat , you must first activate the
convertible locking retractor on the safety be lt
to prevent the child safety seat from moving
~ page 232.
~ Push the child safety seat down w ith your full
weight to get the safety be lt rea lly t ight so that
the seat cannot move forward and sideways more than 1 in (2 .5 cm).
~ Secure unused safety belts on the rear seat
~ page 227.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
stra ined for their age and size.
_&, WARNING
Not using a ch ild safety seat , using the w rong
child sa fety seat or imp roperly installing a
child restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especia lly children
must be restrained properly whenever riding
in a vehicle . An unrestrained or improperly
restrained child could be injured by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
Ch ild safety
An unrestrained or improperly restrained
child is also at greater r isk of injury or death
through contact with an inf lating airbag.
- Commercially available child safety seats
are required to comply with U.S . Federal
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213) .
- When buying a child restra int, select one
that fits your chi ld and the vehicle.
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion . The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequate contact with the seat.
- Always heed all lega l requirements per­
ta ining to the insta llation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using .
- Never allow children under 4 ft
9 in (57 in/
1.45 m) to wear a normal safety belt . H ow­
eve r, the rear seat in the TT Coupe is de­
signed to permit children who are between
4 ft 3 in (1.3 m) and 4
ft 9 in (57 in/1.45 m)
tall to use the available three-point lap and
shoulder safety belts.
- Never let more than one child occupy a chi ld
safety seat .
- Never let babies or o lder children ride in a
veh icle while sitting on the lap of another
passenger.
- Holding a child in your arms is never a sub­
stitute for a child restraint system .
- The strongest person cou ld not ho ld the
ch ild with the forces that exist in an acci­
dent . The child will strike the interior of
the vehicle and can also be struck by the passenger.
- The child and the passenger can also in­
jure each other in an accident.
- Never install rear-fac ing child safety seats
or infant car riers on the front passenger
seat. A child w ill be seriously injured and
can be killed when the passenger a irbag in­
flates -even with an Advanced Airbag Sys­
tem .

Ch ild sa fety
Child seats
Infant seats
Babies and infants up to about one year old and
20 lbs or
9 kg need special rearward -facing child
restraints that support the back , neck and head
in a crash .

~ page 227.
Infants up to about one yea r (20 lbs or 9 kg) a re
best protected in special infant carr iers and child
safety seats designed for the ir age group. Many
expe rts believe that infants and small ch ild ren
shou ld ride o nly in special restra ints in wh ich the
ch ild fa ces the back of the vehicle. These infant
seats support the baby's back, neck and head in a

~ fig. 171 .
The airbag on the passenge r side makes the front
sea t a potent ially dangerous place for a child to
ride. The fron t seat is not the safest place for a
c h ild in a forward -fac ing ch ild seat. It is a
very
dange rous p lace for an infant or a larger chi ld in
a rearward-fac ing seat . .,..

fastened snugly and as low as possible around
the pelvis. Never let the lap belt portion of the
safety belt pass over the child's stomach or abdo ­
men .
I n a crash, a irbags must inflate within a blink of
an eye and with considerable force. In order to do its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu ­
pant moves forward into the a irbag.
A vehicle occupant who is out of position and too
close to the airbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck v iolently and will receive ser ious or
possibly even fatal injury .
In order for the airbag to offer protection, it is important that all vehicle occupants, especially
any children, who must be in the front seat be­
cause of exceptional circumstances, be properly restrained and as far away from the airbag as
possible . By keep ing room between the child's
body and the front of the passenger compart­
ment, the airbag can inflate comp letely and pro ­
vide supp lemental prote ct ion in certain frontal
collisions .
A WARNING
Not using a booster seat, us ing the booster
seat improperly, incorrectly insta lling a boos­
ter seat or using the vehicle safety belt im­ properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situat ion. To help reduce the risk of se­
r ious personal inju ry and/or death:
- The shoulder belt must lie as close to the
center of the child 's collar bone as possible
and must lie flat and snug on the uppe r
body .
It must neve r lie across the th roat or
neck. The lap belt must lie across the pelv is
and never across the stomach or abdomen.
Make sure that the belt lies flat and snug .
Pull on the belt to tighten if necessary.
- Failure to proper ly route safety belts over a
child's body will cause severe injuries in an
acc ident or other emergency situation
9 page 189 .
Ch ild safety
- The rear side of the ch ild safety seat should
be positioned as close as possible to the
backrest on the veh icle seat.
- Ch ildren on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even k illed when an airbag inflates.
- Never let a chi ld stand or kneel on any seat,
for example the front seat.
- Never let a chi ld r ide in the cargo area of
your veh icle.
- Always remember that a chi ld leaning for­
ward, sitt ing sideways or o ut of pos ition in
any way du ring an accident can be struck by
a dep loying airbag. Th is w ill resu lt in serious
pe rsonal injury or death.

the safety be lt is locked so that the ch ild and
c hi ld safety seat will stay in place .
Always remembe r: E ven thoug h your veh icle is
equipped wi th an Advan ced Airba g system, all
c hi ldren, especially those 12 yea rs and younger,
shou ld always ride in the back seat proper ly re ­
strained for their age and size .
A WARNING
Improperly installed child safety seats in­
crease the r isk of serious personal injury and
death in a co llision .
-
-Always make sure that the safety be lt re­
tractor is locked when installing a c hild
safety seat. An unlocked safety be lt retrac­
to r cannot hold the ch ild safety seat in place
during normal d riving or in a c rash.

Gasoline grade
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gasoline can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/

the eng ine.
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol o r MT BE (commonly referred to as oxygen­
ates) if the blended m ix tu re meets t he fo llow ing

ers is carbon deposit build-up ca used by the type
of gasoline yo u use.
A lt hough gasoline grades d iffer from one manu ­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Dete r­
gent Gasoline, please go to the official website
(www.toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
g ine of peak performance.
