What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver's ability to concentrate on the road
without being distracted.
The driver is responsible for the safety of the
veh icle and a ll of its occupants . If your ability
to drive is impaired, safety risks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road ¢
,&..
Therefore:
.. Do not let yourself be distracted by passen­
gers or by us ing a cellular telephone.
.. NEVER drive when your driv ing ability is im­
paired (by medicat ions, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road
and speed limits and plain common sense.
.. ALWAYS adjust your speed to road, traffic
and weather condit ions .
.. Take frequent breaks on long trips . Do not
drive for more than two hours at a stretch .
.. Do NOT drive when you are tired, under
pressure or when you are stressed.
A WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used .

Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 91 The correct d istance between d river a nd stee r­
in g whee l
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
foll owing pos ition:
.,. Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floor
while keeping your knee(s) slightly bent
q&_ ,
.. Adjust the angle of the seatback so that it is
in an upright position so that your back
comes in full contact with it when you drive.
.. Adjust the steering wheel so that there is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and your breast
bone ¢
fig. 91. If not possible, see your au­
thorized Audi dealership about adaptive
equ ipment .
.. Adjust the steer ing wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face .
.. Grasp the top of the steering wheel with
your elbow(s) slightly bent .
.. Adjust the head restraint so the upper edge
is as even as possible with the top of your
head . If that is not poss ible, try to adjust
the head restraint so that it is as close to
this position as possible .
.. Fasten and wear safety belts correctly

General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are nec­
essary, how they work and how to adjust and
wear them correctly .
.. Read all the information that follows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death.
- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving.
- Pregnant women, injured, or physically
impaired persons must also use safety
belts. Like all vehicle occupants, they are
more likely to be seriously injured if they
do not wear safety belts. The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi TT Coupe has two seating positions in the front and two height-limited seating
positions in the rear. Each seating position has
a safety belt. The rear seat area in your Audi
TT Coupe does not have enough room for pas­
sengers of all sizes. For reasons of safety, no
person taller than 4'11" (1.S meters) should
ever ride in the rear seat area.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. -
Never strap more than one person, in­
cluding small children, into any belt.
It is
especially dangerous to place a safety belt over a child sitting on your lap.
- Never let more people ride in the vehicle
than there are safety belts available.
- Be sure everyone riding in the vehicle is
properly restrained with a separate safe­
ty belt or child restraint.
- Persons taller than 4'11" (1.5 m) as well
as children in booster seats who are too
close to the rear window and roof can
suffer severe head and neck injuries
when the rear lid is closed or in a crash .
- The minimum clearance between the passenger's heads and the rear window
must never -under any circumstances -
be less that 1 inch (2.5 cm.) when the
passengers sit fully upright.
- Always make sure that rear seat passen­
gers cannot be struck when the rear lid is
closed.
,! Safety belt warning light
Your vehicle has a warning system for the
driver and front seat passenger to remind you
about the importance of buckling-up.
Fig. 94 Safety belt warning light in the instrument
cluster· enlarged
Before driving off, always:
" Fasten your safety belt and make sure you
wear it properly .
.. Make sure that your passengers also buckle
up and properly wear their safety belts.
.. Protect children with a child restraint sys-
tem appropriate for the size and age.
Ill-

The warning light. in the instrument cluster
lights up when the ignition is switched on as a
reminder to fasten the safety belts. In addi ­
tion, you w ill hear a warning tone for a certain
period of time.
Fasten your safety belt and make sure that
your passengers also properly put on their
safety belts.
A WARNING
- Safety belts are the sing le most effective
means availab le to reduce the risk of se­
rious injury and death in automob ile acci­
dents. For your protect ion and that of
yo ur passengers, always correctly wear
sa fety belts when the vehicle is moving.
- Failure to pay attention to the warning
ligh t that come on, could lead to person­
al injury.
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles.
Fig. 95 Unb elted occupa nts in a vehicle head ing for a
wall
Fig. 96 T he ve hicle crashes into the wall.
Safety belts 101
The physical principles are simple . Both the
vehicle and the passengers possess energy
which var ies with vehicle speed and body
weight. Engineers call this energy "kinetic en­
ergy."
The higher the speed of the vehicle and the
greater the vehicle's we ight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor . If
the speed doubles from 15 to 30 mph (25 to
50 km/h), the energy increases 4 times!
Because the occupants in this vehicl e are not
using safety belts¢
fig. 95, they will keep
moving at the same speed the vehicle was
moving just before the crash, until someth ing
stops them - here, the wall¢
fig. 96.
The same principles apply to people sitting in
a vehicle that is involved in a frontal coll ision .
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces acting on the body can
reach one ton (2,000 lbs, or 1,000 kg) or
more . At higher speeds, these forces are even
greater.
Peop le who do not use safety belts are also
not attached to their vehicle . In a frontal colli­
s ion they will also keep moving forward at the
speed their vehicle was travell ing just before
the crash . Of co urse, the laws of physics don't
just apply to frontal collisions, they determine
what happens in all kinds of accidents and col­
lisions .

104 Safety belts
damaged, have belts replaced by an au­
thorized Audi dealer or qualified
workshop.
- Safety belts that have been worn and
loaded in an accident must be replaced
with the correct replacement safety belt
by an authorized Audi dealer or qualified
workshop. Replacement may be necessa­
ry even if damage cannot be clearly seen.
Anchorages that were loaded must also
be inspected.
- Never remove, modify, disassemble, or
try to repair the safety belts yourself.
- Always keep the belts clean . Dirty belts
may not work properly and can impair
the function of the inertia reel

Fastening safety belts
Seat first -everybody buckle up!
,
Fig. 100 Belt buck le an d tongue o n the driver' s seat
To provide maximum protection, safety belts
must always be positioned correctly on the
wearer's body .
• Adjust the fron t sea t and he ad restraint
properly
c:> page 54, General recommenda ­
tions .
• Hold the belt by the tongue and pull it
evenly across the chest and pelvis
c:> &-
• Insert the tongue into the correct buckle of
your seat until you hear it latch securely
c:> fig. 100.
• Pull on the belt to make sure that it is se ­
curely latched in the buckle .
Automatic safety belt retractors
Every safety belt is equipped with an automat­
ic belt retractor on the shoulder belt. This fea­
ture locks the belt when the belt is pulled out
fast, during hard braking and in an accident.
T he belt may also lock when you drive up or
down a steep hill or through a sharp curve.
During normal driving the belt lets you move
freely .
Safety belt pretensioners
The safety belts on the front seats are equip­
ped with a belt pretensioner that helps to
tighten the safety belt and remove slack when
the pretensioner is activated. The function of
the pretensioner is monitored by a warning light
c:> page 15 .
Switchable locking feature
Every safety belt except the one on the driver
seat is equipped with a switchable locking fea­
ture that
must be used when the safety belt is
used to attach a child seat . Be sure to read the
important information about this feature
c:> page 140.
_& WARNING
Improperly positioned safety belts can
cause serious injury in an accident
c:> page 105, Safety belt position .
-Safety belts offer optimum protection
only when the seatback is upright and
belts are properly positioned on the
body .
-
-Never attach the safety belt to the buck­
le for another seat. Attaching the belt to
the wrong buckle will reduce safety belt
effectiveness and can cause serious per­
sonal injury .
- A passenger who is not properly restrain­
ed can be seriously injured by the safety
belt itself when it moves from the stron-
ger parts of the body into cr itical areas
like the abdomen .
- Always lock the- convertible locking re­ tractor when you are securing a child seat in the vehicle

110 Airbag sys te m
Child restraints on the front seat - some
important things to know
• Be sure to read the impo rtant in formation
and head the WARNINGS for important de­
ta ils about ch ildren and Advanced Airbags
i=> page 130.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
all children, especially those 12 years and
younger, a lways ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld safety seat. It
can be a very dangerous place for a n infan t or
a child in a rearward-facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comply with the Requ ire­
men ts of United States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your vehicle was manufact ured.
The Standa rd requires the fron t air bag on t he
passenger side to be turned off ("sup­
p ressed") if a ch ild up to about one yea r of
age restrained in one of the rear-facing or for­
ward-facing infant restraints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re ­
straints that were used to certify compliance
with the US Safety Standard
c> page 132.
The PASSENGE R AIR BAG OFF light in the in­
strument panel tells you when the front Ad­
vanced A irbag on the passenger side has been
turned off by t he e lectronic control unit.
Each t ime you tur n on the ignition, the
PAS ­
SENGER AIR BAG OFF
l ight will come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied ,
- will stay on if there is a small child or child
restraint on the front passenger seat, -
will go off if the front passenger seat is oc ­
cupied by an adult as registered by the
weight -sensing mat
r::!) page 119, Monitor­
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
when the control unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off .
If the total weight on the front passenge r
seat is more than that of a typica l 1 year -old
c h ild b ut less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PAS SENGER
AIR BAG OFF
light does not come on, the
front a irbag on the passenger side has not
been turned off by the elect ronic con trol unit
and can deploy if the control uni t se nses an
impact that meets the cond itions stored in its
memory .
For exampl e, th e airbag ma y deplo y if:
-a small ch ild that is heav ie r than a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whethe r the child is in one of
the child safety seats listed
<:!) page 132), or
- a child who has outgrown ch ild restraints is
on t he front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument pane l and stays on .
The front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not illum inate and stay lit) even if a
small adult o r teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- re cli ned ba ck res t w it h thei r feet on the
vehicle floor in front of the sea t is on the front
passenge r seat
c::> page 91, Proper seating po ­
sition for the driver.
If the front passenger a irbag dep loys, the
F ede ra l St andard req uires the airbag to meet
the "low risk" dep loyment criteria to reduce
the risk of injury t hro ugh interaction wit h the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions ..,_

as defined in the electronic control unit
¢ page 119, PASSENGER AIR BAG OFF light .
Always remember, a chi ld safety seat or infant
carrier installed on the front seat may be
struck and knocked out of position by the rap ­
id ly inflating passenger's airbag in a frontal
coll is ion . T he airbag cou ld greatly reduce the
effectiveness of the child restraint and even
seriously injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for children -when properly
rest ra ined accord ing to their age and si ze - we
s trongly recommend that children always sit
in the back seat¢
page 130, Child Safety.
A WARNING
A child in a rearward-facing child safety
seat insta lled on the front passenger seat
w ill be seriously injured and can be k illed if
t he front a irbag inf lates - even with an Ad­
vanced Airbag System .
- The inflating a irbag w ill hit the child
sa fety seat or infant carrier w it h great
f orce and w ill smash the ch ild safety seat
and child against the backrest , door or
roof .
- Always install rear -facing child sa fety
seats on the rear seat.
- If you mus t install a rearward facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PASSENGER AIR BAG O FF
light does not come on and stay on, im­
med iately install the rear-facing child
safety seat in a rear seating posit ion and
have the a irbag system inspected by you r
Audi dealer.
- Forward-fac ing ch ild safety seats instal­
led on the front passenger's seat may in­
terfere with the deployment of the air­
bag and cause serious person al injury to
the ch ild .
WARNING
If, in exceptional c ir c umstances, you mus t
install a forwa rd -facing child restra int on
the front passenger's seat:
A irbag system 11 1
-Always ma ke sure 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 passenger seat into its
rearmost position in t he seat's fore and
aft adj ustment range, as fa r away from
the airbag as possible before installing
the forward-fa cing ch ild restra int. The
backrest mu st be ad ju sted to an upright
posi tion.
- Ma ke sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time wheneve r the ignit ion is swi tched
on.
A WARNING
To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light wi ll be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itched on .
- If the
PASSENGER AIR BAG OFF light
does not stay on, perform the checks de­
scribed ¢
page 119 , Monitoring the Ad ­
vanced Airbag System .
-Take t he chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
li g ht does not stay on .
- Have the airbag system inspected by
your Aud i dea le r i mmediately .
- Always carefully follow instr uctions from
child restraint manufacture rs when in­
stalling c hild restra ints .
A WARNING
If, in e xcept io na l circumstances, you must
ins tall a forward o r rearwa rd-facing child
restra int on the front passenger's se at:
- Imp roper install ation of ch ild restrai nts
can reduce their effec tiveness o r even
preven t them from providing any protec­
tion. •
•

-The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U .S . Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de­
ployment are met .
-Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was
manufac tured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's head s and upper bodies in frontal crashes.
T he airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
T he front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up­
right , wearing your safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite­
ria are intended to help reduce the risk of in­
jury through interaction with the front airbag that can occur, for example, by being too
Airbag system 113
close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard ¢
page 132 , Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re­
strained on the front passenger seat in one
of the rear-facing or forward-facing infant restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your vehicle was
certified . For a listing of the child restraints
that were used to certify your vehicle's com­ pliance with the US Safety Standard
¢page 132,
-weight less than a threshold level stored in
the control unit is detected on the front pas­
senger seat.
When a person is detected on the front pas­ senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing or forward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­
quires the front airbag to be turned off. If the
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory.
If the total weight on the front passenger
seat is more than that of a typical 1 year-old , ..,. •
•

but less than the weight of a small adu lt, the
front airbag on the passenger side may deploy (the
PASSENGER AIR B AG OFF light does not
come on).
F or exa mple , the air b ag m ay 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 whe ther the child is in one of
the chi ld safety seats listed
~ page 132),
- a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the cente r
of the instrument panel w ill come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adult or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upright with
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenger seat.
If the front passenger airbag deploys, the Federal Standard requires the airbag to meet
the "low risk " deployment criteria to help re­
duce the risk of inju ry through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the e lectronic control
un it
~ page 119.
Alw ays re m emb er: Even tho ugh you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of in jury is much higher . -
You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in­
flates - even w ith an Advanced A irbag
~ page 108 .
A WARNING '"----
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag infla tes - even with an Ad­
vanced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is de signed to turn off the
front airbag when a rearward -facing
child restraint has been installed on the
front passenger seat, nobody can abso­
lutely g uarantee that dep loyment is im­
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat and child aga inst the bac krest, door, or
roof .
- Always install rearward-facing ch ild re­
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat be cause of exceptiona l circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately insta ll the rear -fac ing child
safety seat in a rear seating position and
have the airbag system inspected by your
Aud i dealer.
A WARNING
If, in exceptional circumstances, you must
i nstall a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacture r fo r 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 passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing child restraint . The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
lo t of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
electronic control unit when the ignition is on.
The control unit monitors the Advanced Air­
bag System and turns the airbag indicator
light on when a malfunction in the system
components is detected. The function of the
airbag indicator light is described in greater
detail below. Because the front passenger
seat contains important parts of the Ad­
vanced Airbag System, you must take care to
prevent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airbag System
consists of the following:
- Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air­
bag System about the severity of the crash.
-An electronic control unit, with integrated
crash sensors for front and side impacts .
The control unit "decides" whether to fire
the front airbags based on the information
r eceived from the crash sensors. The control
Airbag system 115
unit also "decides" whether the safety belt
pretensioners should be activated.
