Safety belts
General notes
Always wear safety belts!
Wearing safe ty bel ts correctly saves lives!
This chapter exp lains why safety be lts are nec ­
essary, how they work and how to adjust and
wear them correctly .
.. Read a ll the information that fo llows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of ser ious
personal in jury and death .
- Safety belts are the sing le most effective
means avai lab le to reduce the risk of se­
r ious injury and dea th in a utomob ile acci­
dents . For your protection and that of
yo ur passenge rs, always co rrectly wear
safety belts when the vehicle is moving .
- Pregnant women, injured, or physically
im paired perso ns m ust also use safety
belts . Lik e all veh icle occup ants, they are
more like ly to be ser iously injured if they
do not wea r safety be lts . The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi TT Roadster has two seating posi­ tions. Each sea ting pos it ion has a sa fety be lt .
A WARNING
Not wearing safety belts or weari ng them
improperly increases the risk of ser io us
personal i njury and death.
- Never st rap more than one pe rson, in­
cluding small ch ild ren, into any belt. It is
especially dange rous to place a safety
belt over a child s itting on y our lap.
- Never l et mo re peop le ride in the ve hicl e
than there are safety be lts ava ilable. -
Be s ure everyone riding in the vehicle is
properly restrained w ith a separate safe ­
ty belt or child restra int.
4 Safety belt warning light
Your vehicle hos o warning system for the
driver and front seat passenger to remind you
abou t the importance of buckling-up.
Fi g. 101 Safety bel t warni ng lig ht in the instr ument
cl uster -e nla rg ed
Befor e driv ing off, always:
.. Fas ten yo ur safe ty belt and make sure you
wear it properly.
.. Make s ure that your passenge rs also buck le
up and properly wear their safety be lts.
.. Protect children with a child restraint sys-
tem appropriate for the s ize and age .
T he warning light . in the instrument clus­
ter lights up when the ig nition is switched on
as a reminder to fasten the safety belts . In ad­
dition, you will hear a warning tone for a cer­
ta in period of time .
Fasten your safety belt and make sure that
your passengers also properl y put on the ir
safety belt s.
A WARNING
-Safety belts are the s ingle most effec tive
means ava ilable to reduce the risk of se­
rio us inju ry and death in au tomobile a cci­
dents . Fo r you r protection and tha t of
your passengers, a lways cor rectly wear
safety belts when t he vehi cle is moving .
- F ailure to p ay a tten tion to the w arn ing
light that come on, could lead to person­
a l injury.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 102 Unbelted occupants in a ve hicle heading for a
wall
Fig. 103 The vehicle c ras hes into the wall.
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies 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 weight, 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 vehicle are not
using safety belts
r::;, fig. 102, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them -here, the wall
c:> fig . 103 .
The same principles apply to people sitting in
a vehicle that is involved in a frontal collision .
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces acting on the body can
Safety belts 101
reach one ton (2,000 lbs, or 1,000 kg) or
more. At higher speeds, these forces are even
greater.
People who do not use safety belts are also
not attached to their vehicle. In a frontal colli­
sion they will also keep moving forward at the
speed their vehicle was travelling just before
the crash. Of course, the laws of physics don't
just apply to frontal collisions, they determine what happens in all kinds of accidents and col ­
lisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 104 A driver not wear ing a safety belt is v io len tly
thrown forward
Unbelted occupants are not able to resist the
tremendous forces of impact by holding tight
or bracing themselves . Without the benefit of
safety restraint systems, the unrestrained oc­ cupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way r::;, fig . 104 . This impact
with the vehicle interior has all the energy
they had just before the crash.
Never rely on airbags alone for protection .
Even when they deploy , airbags provide only
additional protection . Airbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver, must
wear safety belts correctly in order to mini­
mize the risk of severe injury or death in a
crash.

102 Safet y belt s
Remember too, that airbags wi ll deploy on ly
once and that your safety belts are always
there to offer protect ion in those accidents in
which airbag s are not suppo sed to deploy or
when they have already deployed . Unbelted
occupants can also be thrown out of the vehi ­
cle where even more severe o r fatal inju ries
can occu r.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision. It's simply
not tru e!
Fig . 10 5 Driver is properl y re strain ed in a sudd en br ak­
ing man euve r.
Safety belts used properly can make a big dif ­
ference . Safety be lts help to keep passengers
in their seats , g radually reduce energy levels
applied to the body in an accident, and help
preven t the uncontro lled moveme nt that can
cause serious injur ies . In additio n, safety belts
reduce the danger of being thrown out of the
ve hicle .
Safety belts attach passengers to the car and
g ive them the benefit of being s lowed down
more gently or "softly" t hrough t he "give" in
the safety belts , crush zones and other safety
fe atures engineered into today's vehicles. By
"absorb ing" the kinetic energy over a longer
period of time, the safety belts make the
forces on the body more "to lerable" and less
likely to cause injury .
Although these examples are based on a fron­ tal collision , safety belts can also subs tan tial­
ly reduce the risk of injury in other k inds of
crashes . So, whether you' re on a long tr ip or
just going to the corner store, always buckle u
p and make sure others do, too. Accident sta ­
tist ics show that veh icle occupants properly
wearing safety belts have a lower risk of be ing
injured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen ­
tal airbags to do the ir job i n a collision . Fo r
t hi s reason, wea ring a safety belt is legally re­
quired in mos t countr ies includi ng m uch of
t h e Un ited States and Canada .
Although your Aud i is equipped wi th a irbags,
you still have to wear the safety be lts prov id­
ed. Front ai rbags , fo r example , a re activated
only in some front al collisions. The fron t air­
bags are not act ivated in a ll frontal coll is ions,
in side and rear co llisions, in roll overs or in
cases where there is not eno ugh deceleration
through impact to the front of the veh icle.
The same goes for the other a irbag systems in
your Aud i. So, always wear yo ur safety belt
and make su re everybody in your veh icle is
properly restrai ned!
Important safety instructions about
safety belts
Safety belts must always be properly posi­
tioned across the strongest bones of your
body.
" Always wear safety belts as illust rated and
descr ibed in th is chapte r.
" Ma ke su re that yo ur safety belts are always
ready for use and are not damaged.
A WARNING
-
Not wear ing safety be lts or wearing them
i mproperly i ncreases the r is k of se rious
personal injury and death. Safety belts can
work on ly when used correctly.
- Always fasten your safety belts correct ly
befo re driving off and make sure all pas­
sengers are properly restrained.
- For maximum protection, safety belts
must always be pos itioned c orrectly on
the body .

-Never strap more than one person, in­
cluding small children, into any single
safety belt.
- Never place a safety belt over a child sit­
ting on your lap.
- Always keep feet in the footwell in front
of the seat while the vehicle is being driv­
en.
- Never let any person ride with feet on
the instrument panel or sticking out the
window or on the seat.
- Never remove a safety belt while the ve­ hicle is moving. Doing so will increase
your risk of being injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable
objects in or on your clothing, such as
eye glasses, pens, keys, etc., as these
may cause injury.
- Never wear the shoulder part of the belt under your arm or otherwise out of posi­
tion.
- Several layers of heavy clothing may in­
terfere with correct positioning of belts
and reduce their effectiveness.
- Always keep belt buckles free of anything
that may prevent the buckle from latch­
ing securely .
- Never use comfort clips or devices that
create slack in the shoulder belt. Howev­
er, special clips may be required for the
correct use of some child restraint sys­
tems.
- Never allow safety belts to become dam­
aged by being caught in door or seat hardware.
- Torn or frayed safety belts can tear and
damaged belt ha rdware can break in an
accident. Inspect belts regularly.
If web­
bing, bindings, buckles, or retractors are
damaged, have belts replaced by an au­
thorized Audi dealer or qualified work ­
shop.
- 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 be lts
may not work properly and can impair
the function of the inertia reel¢

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 .
The belt may a lso lock when you drive up or
down a steep hill or through a sha rp curve.

104 Safety belts
During normal driving the belt lets you move
freely.
Safety belt pretensioners
The safety belts are equipped with a belt pre­
tensioner that helps to tighten the safety belt
and remove slack when the pretensioner is ac­
tivated. The function of the pretensioner is
monitored by a warning light
q 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
¢ page 137.
.&_ WARNING
Improperly positioned safety belts can
cause serious injury in an accident
¢ page 104, 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 critical areas
like the abdomen.
- Always lock the convertible locking re­
t ractor when you are securing a child
seat in the vehicle

-
- The shoulder belt should lie as close to
the center of the collar bone as possible and should fit well on the body. Hold the
belt above the latch tongue and pull it
evenly across the chest so that it sits as
low as possible on the pelvis and there is
no pressure on the abdomen . The belt
should always fit snugly
¢ fig . 10 7. Pull
on the belt to tighten if necessary .
- The lap belt portion of the safety belt
must be positioned as low as possible
across pelvis and never over the abdo­
men . Make sure the belt lies flat and
snug
q fig. 107. Pull on the belt to tight­
en if necessary.
- A loose-fitting safety belt can cause seri­
ous injuries by shifting its position on
your body from the strong bones to more vulnerable, soft tissue and cause serious
injury.
- Always read and heed all WARNINGS and
other important information

risk of being inj ured or k illed.
Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries.
Wearing safety belts improperly can cause se­
rious injury or death. Safety belts can only
work when they are correctly positioned on
the body . Improper seating pos itions reduce
the effectiveness of safety be lts and will even
increase the risk of injury and death by mov­
ing the safety be lt to crit ica l areas of the
body. Improper seating positions a lso in­
crease the risk of serious injury and death
when an airbag dep loys and strikes an occu­
pant who is not in the correct seati ng posi­
tion. A driver is respons ible for the safety of
all vehicle occupants and especially for chil­
dren. Therefore:
.. Never permit anyone to assume an incorrect
sitting position in the vehicle while traveling

Safety belt preten­
sioners
How safety belt pretensioners work
In front and side collisions above a particular
severity , safety belts in use are tensioned au ­
tomatically .
The safe ty belts are equippe d with safety be lt
pretensioners. The sys tem is activated by sen ­
sors in front and side collisions of great se­
verity. This tightens the belt and takes up belt
slack
c::> .&. in Service and disposal of safety
belt pretensioner on page 106.
Tak ing up the
slack helps to reduce forward occupant move­
ment during a co llision .
(D Tips
The safety be lt pretensioner can only be
activated once.
- In m inor frontal and side coll isions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
fo rce , the safety belt pretens io ner are
not act ivated.
- When the safety be lt pretensioner is ac­
tivated, a fine dust is released . This is
no rma l and is not caused by a fi re in the
vehicle.
- The rel eva nt safety requirements must
be obse rved when t he vehicle or compo­
nen ts of the system are scr ap ped . A
q ualified dea le rship is famili ar wi th
these re gulations and w ill be pleased to
p ass on the informat io n to you. - Be sure to observe all safety, env
iron ­
menta l and other regu lations if the ve hi­
cle or individual parts of the system, par­
ticu larly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this service fo r you.

Airbag system
Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, a lways:
• Adjust the driver's seat and steering wheel
properly
c:> page 92,
• Adjust the front passenger's seat properly
c:> page 60,
• Wear safety be lts properly c:> page 102,
• Always properly use the proper child re-
straint to protect children
c:> page 129.
In a collision airbags must inflate within the
blink of an eye and with considerable force .
The supplemental airbags can cause injuries if
the dr iver or the front seat passenger are not
seated properly . Therefore in order to help the
a ir bag to do its job, it is important, both as a
d river and as a passenge r to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compa rtment, the airbag can inflate fully and
comp letely and provide supp lemental protec­
tion in ce rtain frontal collisions
c:> page 92,
Proper occupant seating positions . For detai ls
on the operat ion of the seat adjustment con­
trols
c:> page 60 and c:> page 61.
I t's especially important that children a re
properly restrained
c:> page 129.
There is a lot that the d river and the passen­
ger can and must do to help the individua l
safety features ins talled in your A udi work to­
gether as a system.
Prope r seat ing pos ition is important so that
the front airbag on the drive r side ca n do i ts
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals, or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified workshop, or call Audi Customer Re­
lations at 1-800-822-2834 for poss ible modi­
fi cat ions to your veh icle.
When the airbag system deploys, a gas gener ­
ator will f ill the a irbags, break open t he pad­
ded cove rs, and inflate between the steering
whee l and the dr ive r and between the instru­
ment pane l and the fron t passenger. The a ir­
bags will deflate immediately after dep loy­
ment so that the front occupants can see
t hr ough the windshie ld again witho ut inter­
ruption .
All of th is takes p lace in the b link of an eye, so
fast that many peop le don't even realize that
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
should be in their way when they deploy.
Front a irbags in combination wi th properly
worn safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and passenger from
hitting parts of the inside the vehicle while re­
ducing the fo rces acting on t he occ upan t dur­
ing the crash . In this way they help to reduce
the risk of injury to the head and upper body in the crash. Airbags do not protect the arms
or the lower parts of the body.
Both front airbags wi ll not inflate in all fronta l
collisions . The triggering of the a irbag system
depends on the vehicle dece leration rate
caused by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed in to the con­
trol unit , the airbags will not be triggered ,
even though the car may be badly damaged as
a resu lt of the co llision . Ve hicle damage, re­
pair costs o r even the lack of ve hicle damage
is not necessarily an indica tion of whether an
airbag shou ld inflate or not .
It is not possib le to define a range of vehicle
speeds that w ill cove r every possib le kind and .,.
