Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 1 36 Unbe lted occupants in a ve hicle head ing for a
wall
Fig. 137 T he vehicle cras hes into the wall
The physical principles are simple. Both the
veh icle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
e rgy."
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 ene rgy increases 4 t imes!
Because the passengers of th is veh icle are not
using safety belts¢
fig. 136, they will keep
mov ing at the same speed the vehicle was
mov ing just befo re the crash, unt il something
stops them - here, the wall ¢
fig. 137.
Safety belts 135
The same principles apply to people s itting in
a vehicle that is involved in a frontal coll ision .
Even at c ity 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 greater speeds, these fo rces are even
highe r.
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 veh icle was travel ling just before
the crash . Of co urse, the laws of physics don't
just app ly to frontal collisions, they determine
what happens i n all k inds of a cc ident s and col­
li s ions.
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!

occupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way
c::> fig. 138. This impact
with the vehicle interior has all the energy
t hey had just before the crash.
Never rely on a irbags 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.
Remember too, that airbags will deploy only
once and that your safety belts are always
there to offer protection in those accidents in
which airbags are not supposed to deploy or
when they have already deployed . Unbelted
occupants can also be thrown out of the vehi­
cle where even more severe or fatal injuries
can occur.
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and othe r passen­
gers ~
fig. 139. In a frontal collision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas­
senger .
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision . It's simply
not true !
Fig. 140 Driver is co rr ect ly re strain ed in a sudd en brak­
ing maneuve r
Safety belts used properly can make a big dif­
ference. Safety belts help to keep passengers
in their seats, gradually reduce energy levels
applied to the body in an accident, and help
prevent the uncontrolled movement tha t can
cause serious injuries . In addition, safety belts
reduce the danger of being thrown out of the
vehicle .
Safety belts attach passengers to the car and
give them the benefit of being slowed down
more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features engineered into today's vehicles. By
"absorbing " the kinetic energy over a longer
period of ti me, the safety belts make the
forces on the body more "tolerable" and less
likely to cause injury.
Although these examples are based on a fron­
tal collision, safety belts can also substantial­
ly reduce the r isk of injury in other kinds of
crashes. So, whether you're on a long trip or
just going to the corner store, always buckle up and make sure others do, too. Accident sta­
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of being
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 their job in a collision . For
this reason, wearing a safety belt is legally re­
quired in most countries including much of
the United States and Canada.
Although your Audi is equipped with airbags,
you still have to wear the safety belts provid­
ed. Front airbags , for example, are activated
only in some frontal collisions. The front air­
bags are not activated in all frontal collisions,
in side and rear collisions, in roll overs or in
cases where there is no t enough decelera tion
through impact to the front of the vehicle .
The same goes for the other airbag systems in
your Audi . So, always wear your safety belt
and make sure everybody in your vehicle is
properly restrained!

Important safety instructions about
safety belts
Safety belts must always be correctly posi­
tioned across the strongest bones of your
body.
~ Always wear safety belts as illustrated and
described in this chapter.
~ Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. Safety belts can
work only when used correctly .
- Always fasten your safety be lts correctly
before driving off and make sure all pas­
sengers are correc tly restrained.
- For maximum protection, safety belts must always be positioned properly on
the body .
- Never strap more than one person, in­
cluding small children, into any 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 d riv­
en .
- Never let any person ride with their 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 be ing 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 allow safety belts to become dam­
aged by being caught in door or seat
hardware .
- Do not wear the shoulder part of the belt
under your arm or otherwise out of posi ­
tion . Safety belts

- Several layers of heavy clothing may in­
terfere with correct positioning of belts and reduce the overall effectiveness of
the system .
- Always keep belt buckles free of anything
tha t 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 requ ired for the
proper use of some child restraint sys­
tems .
- Torn or frayed safety belts can tear, and
damaged belt hardware 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 . Replace­
ment may be necessary 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 bel ts clean. Dirty belts
may not work properly and can impair
the function of the inertia reel

Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries.
Wear ing safety be lts imprope rly can cause se ­
rio us inj ury or death. Safety be lts can on ly
wo rk when they are correct ly positioned on
the body. Improper seating positions reduce
the effect iveness of safety belts and will even
increase the r isk of injury and death by mov­
ing the safety belt to cr itical areas of the
body. Imprope r seat ing pos it ions also in­
crease the risk of serio us in jury and death
when an air bag deploys and str ikes a n occu­
pant who is not in the correct seating posi­
tion . A d river is responsib le for the sa fety of
all vehicle occupants and especially for chi l­
dren. Therefore:
~ Never permit anyone to ass ume an incorrect
sitting position in the veh icle w hile traveling
¢&_ .
A WARNING
Imprope rly worn safety belts increase the
r isk of serious personal injury and death
whenever a veh icle is being used. -
Always make sure that all vehicle occu­
pants are co rrectly restrained and stay in
a correct seating position whenever the
veh icle is being used .

Safety belt preten­
sioners
How safety belt pretensioners work
In front, side and rear -end collisions above a
particular severity and in a rollover , safety
belts are tensioned automatically.
Reversible safety belt tensioners
T he safety belts on the fro nt sea ts ar e e qui p­
ped with powe r reversib le tensioners . The fo l­
lowing functions a re ava ila bl e when the driv­
er's/front passenger's safety belts are fas­
tened :
- Automatic tens ioners : at the star t of a drive,
the safety belts automat ica lly adjust to the
passe nger afte r a certain time period or ve ­
hicle speed. To switch the automatic ten­
sioners off, select the following in the MMI:
! CARI function button> Car systems > Vehi­
cle settings > Seats > Driver's seat or Pas­
s enger's seat
> Automatic belt t ensioner >

reve rsible tensioning function in minor co lli­
sion s.
Pyrotechnic safety belt pretensioners
The safety belts are equ ipped with safety belt
pre tensioners . The system is act ivated by se n­
sors i n front, s ide and rear-end co llisions of
great severity and in a rollover. This tig htens

and disposal of safety belt pretensi oner on
page 141.
Taking up the slack helps to reduce 1111>

forward occupant movement during a colli­
sion.
A WARNING
- It is possible for the pretensioners to de­
ploy incorrectly.
- The pyrotechnic system can only provide
protection for one collision . If the pyro­
technic pretensioners deploy, the preten­
sioning system must be replaced.
(D Tips
The pyrotechnic safety belt pretensioners
can only deploy once.
- The safety belt pretensioners do not de­
ploy in minor frontal and side collisions,
in rear-end collisions, in rollovers and in
collisions involving very little impact
force .
- A fine dust is released when the pyro­
technic safety belt pretensioners deploy.
This is normal and is not caused by a fire
i n the veh icle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped . A
qualified dea lership is familiar with
these regulations and will be pleased to
pass on the information to you.
- Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this
service for you.
Service and disposal of safety belt
pretension er
The safety belt pretensioners are parts of the
safety belts on your Audi . Installing, remov­
ing, servicing or repairing of belt pretension­
ers can damage the safety belt system and prevent it from working correctly in a colli­
sion.
There are some important things you have to know to make sure that the effectiveness of
Safety belts 141
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment .
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly :
- The belt pretensioner system can be acti­ vated only once .
If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety be lt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­
pair manual, training and special equip­
ment necessary.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of the
restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is fami liar with these requirements
and we recommend that you have your
dealer perform this service for 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, always:
• Adjust the dr iver's seat and steering wheel
properly ¢
page 125,
• Adjust the front passenger's seat properly
r=;page 55,
• Wear safety be lts properly r=; page 13 7,
• Always properly use the proper child re-
stra int to protect children¢
page 166.
In a collision, airbags must inflate within the
blink of an eye and with considerable force .
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to he lp the
a irbag to do its job, it is important, both as a
d river and as a passenger to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag ca n inflate fully and
comp letely and provide supp lemental protec­
tion in certain frontal collisions¢
page 125,
Proper occupant seating positions .
For detai ls

It's especially important that children a re
properly restrained ¢
page 166.
There is a lot that the driver and the passen­
gers 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 driver s ide can 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 peda ls , 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
ficat ions to your ve hicle.
When the airbag system deploys, a gas gener ­
ator will f il l the a irbags, break open t he pad­
ded cove rs, and i nflate between the steer ing
whee l and the dr iver and between the instru­
ment pane l and the front passenger. The a ir­
bags will deflate immediately after dep loy­
ment so that the front occupants can see
t h rough 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 tha t
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
shou ld be in their way when they deploy.
Front airbags in combination with properly
wor n safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and front seat pas­
senger from hitting pa rts of the inside of the
vehicle while reducing the forces acting on the
occupant dur ing the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. A irbags 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 t riggering of the airbag system
depends on the vehicle dece lerat ion rate
caused by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed into the con ­
t rol unit , the airbags will not be trigge red,
even though the car may be badly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs or even the lack of ve hicle damage
is not necessari ly an indication of whether an
airbag shou ld inflate or not .
