General information
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety be lts are neces­
sary, 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.
&_ WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death.
- Safety belts are the s ingle most effective
means ava ilable to reduce the risk of serious
injury and death in automobile accidents.
For your protect ion and that of your passen­
gers, always co rre ctly wea r safety be lts
when the vehicle is moving .
- Pregnant wome n, inju red, o r physically im­
paired persons mus t also use safety be lts.
L ik e all vehicle occ upants, they are mo re
likely to be serio usly injured i f they do not
wea r safety be lts. The best way to protect a
fetus is to protect the mother -throughout
the ent ire pregnancy .
Number of seats
Your Audi has a total of four seating positions:
two in the front and two in the rear. In some
veh icles, there are f ive seating positions: two in
the front and three in the rear . Each seating posi­
tion has a safety belt .
&_ WARNING
Not wea ring safety belts or weari ng them im­
pro perly in cre ases the risk of ser io us personal
injury and dea th.
- Never st rap more tha n one perso n, includ­
ing small ch ild ren, in to any be lt .
It is espe­
c ia lly da ngerous to place a safety belt over a
child sitting on your lap .

-Never let more people ride in the vehicle
than there are safety be lts available .
- Be sure everyone riding in the vehicle is
properly restrained with a separate safety
be lt or ch ild restraint.
~ Safety belt warning light
Your vehicle has a warning system for the driver
and front seat passenger (on USA models only) to remind you about the importance of buckling­
up .

Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 145 Unbelted occupants in a vehicle heading for a wall
Fig. 146 The vehicle crashes into the wall
The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­ ies with vehicle speed and body weight. Engi­
neers call this energy "kinetic energy."
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.
Veh icle speed is the most significant factor. If
the speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 t imes!
Because the passengers of this vehicle are not us­
ing safety belts¢
fig. 145, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall¢
fig. 146 .
Safety belts
The same p rinciples apply to people sitting in a
vehicle that is invo lved in a fronta l co llision. 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 greater
speeds, these forces are even higher.
People who do not use safety belts are a lso not
attached to the ir vehicle. In a frontal collis ion
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 collisions .
What happens to occupants not wea ring
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 14 7 A driver not wearing a safety belt is violently
thrown forward
Fig . 148 A rear passenger not wearing a safety belt will fly
forwa rd and strike the driver
Unbelted occupants are not able to resist the tre­
mendous forces of impact by holding tight or
bracing themselves . Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam v iolently into the steering wheel,

instrument panel, windshield, or whatever else is
in the way
r:!> fig. 147. This impact with the vehi­
cle interior has all the energy they had just be­
fore the crash.
Never rely on airbags alone for protection . Even
when they deploy, airbags provide only additional
protection. A irbags are not supposed to dep loy in
all kinds of accidents. A lthough your Audi is
equipped w ith airbags, all vehicle occupants, in­
cluding the driver, must wear safety belts cor­
rectly in order to minimize the risk of severe in­
jury or death in a crash .
Remember too, that airbags will deploy only
once and that your safety belts are always there
to offer protect ion in those accidents in wh ic h
airbags are not supposed to deploy or when they
have a lready deployed . Unbel ted occupants can
also be thrown o ut of the veh icle where eve n
mo re severe or fatal injuries can occur .
It is also important for the rear pass engers to
wear safety belts correctly. Unbelted passengers
i n t he re ar seats endanger no t on ly themse lves
but also the drive r and other passengers
~ fig . 148. In a frontal collision they will be
thrown forward violently, where they can hit and
in jure the driver and/or front seat passenger.
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!
F ig . 14 9 Driver is co rrectly restrai ned in a sudde n brak ing
m aneu ver
Safety belts used properly can make a b ig d iffer­
ence. Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap-
142
plied to the body in an accident , and help prevent
the uncontrolled movement that can cause seri­
ous injuries. In add ition, sa fety belts red uce the
danger of being thrown out of the vehicle.
Safety be lts attach passengers to the car and g ive
them the benefit of being s lowed down more
gently or "soft ly" thro ugh the "give" in the safety
belts, crush zones and other safety feat ures engi­
neered into today's vehicles. By "absorbing" the
k inet ic energy over a longer per iod of t ime, the
safety belts make the forces on the body more
"tolerab le" and less likely to cause inju ry .
Although these examples are based on a frontal
collision, safety be lts ca n also substantially re ­
duce the r isk o f injury in ot her kinds of crashes .
So, whethe r yo u're on a long trip or just goi ng to
the cor ne r store, a lways b uckle up and make s ure
othe rs do, too. Ac ciden t st at ist ics show that veh i­
cle o ccupants prope rly wearing safety bel ts have
a lowe r risk of being injured and a m uch better
chance of surviving an acc ident . Properly using
safety be lts also great ly increases the ability of
the supp lemental airbags to do their job in a col­
li sion. For this reason, wearing a safety belt is le­
gally required in most countries including much
of the United States and Canada .
Although your Aud i is equipped with airbags, you
still have to wear the safety belts provided. Front
airbags, for examp le, are activated only in some
frontal collisions. The front airbags are not act i­
vated in all frontal collisions, in side and rear co l­
li sions, in rollovers or in cases whe re there is not
eno ugh deceler ation throug h impa ct to the front
of the vehicle . The same goes for the other a irbag
systems in your Audi. So, always wear your safety
belt and make sure everybody in your vehicle is
properly rest rained!

A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death . Safety belts can work only
when used correctly.
-Always fasten your safety belts correctly be­ fore driving off and make sure all passen­
gers are correctly restrained.
- For maximum protection, safety belts must
always be positioned properly on the body .
- Never strap more than one person, includ­
ing small children, into any belt .
- Never place a safety belt over a child sitting
on your lap.
- Always keep feet in the footwell in front of
the seat while the vehicle is being driven.
- 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 vehicle
is moving . Doing so will increase your risk of
being injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable ob-
jects 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 hard­
ware.
- Do not wear the shoulder part of the belt
under your arm or otherwise out of position .
- Several layers of heavy clothing may inter­
fere with correct positioning of belts and re­
duce the overall effectiveness of the system.
- Always keep belt buckles free of anything
that may prevent the buckle from latching
securely .
- Never use comfort clips or devices that cre­
ate slack in the shoulder belt . However, spe­
cial clips may be required for the proper use
of some child restraint systems.
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an acci­
dent. Inspect belts regularly.
If webbing,
bindings, buckles, or retractors are dam-
Safety belts
aged, have belts replaced by an authorized
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 au­
thor ized Audi dealer. Replacement may be
necessary even if damage cannot be clearly
seen. Anchorages that were loaded must al­
so 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 func­
tion of the inertia reel¢

Safe ty belts
Autom ati c s afet y belt retr actors
Every safety belt is equ ipped with an automa tic
be lt retractor on the shoulder belt. This feature
locks the belt when the belt is pulled out fast,
during hard braking and in a n accident . The belt
may a lso lock when you drive up or down a steep
hill or through a sharp curve. Dur ing normal driv­
ing the belt lets you
move freely .
Safety belt p ret en sion ers
The safety belts are equipped with a belt preten­
sioner that helps to t ighten the safety belt and
remove slack when the pretensioner is activated
¢
page 146 . The function of the pretensioner is
mon itored by a warn ing light¢
page 17.
Con vertible loc king retracto r
Every safety belt except the one on the driver
seat is equipped with a convertible locking retrac­
tor 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 183 .
.&_ WARNING
Improperly pos it ioned safety be lts can cause
ser ious injury in an accident ¢

Safety belt position.
- Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body.
- Always make sure that the rear seat bac k­
rest to which the center rea r safety belt* is
attached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a crash.
- Never attach the safety belt to the buckle for another seat. Attaching the belt to the
wrong b uckle will reduce safety belt effec­
t iveness and can cause serious persona l in­
jury.
- A passenger who is not properly restrained can be seriously in jured by the safety be lt it­
self when it
moves from the stronger parts
144
of the body into critical areas like the abdo­ men.
- Always lock the convertible locking retractor
when you are securing a child seat in the ve­
hicle

Belt tensioners
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 tensioner s
The safety belts on the front seats are equipped
with power revers ible tensioners. The following
funct io ns are available when the dr iver's/front
passenger 's safety belts are faste ned:
- Automatic tensione rs: at the start of a drive,
the safety belts automat ica lly adjust to the
passenger after a certain time period or ve hicle
spee d. To switch the a utomat ic tens ioners off,
select the following in t he M MI :
!CARI function
button
> ( Car )* systems > Vehicle settings >

- The s afety be lts may also tigh ten with this re-
vers ible tension ing f unct io n in m ino r collisions .
Pyrotechnic safety belt pretensioners
The safety belts are eq uipped w it h safety bel t
pretensione rs. The system is activa ted by se nsors
i n front, s ide a nd r ear-end collisions of grea t se ­
verity and in a ro llover. This tig htens the bel t and
takes up belt slack
c> &. in Service and disposal of
safety belt pretensioner on page 147.
Taking up
the slack helps to reduce forward occupant
movement during a collision.
A WARNING
-It is poss ible for the pretensioners to dep loy
incorrectly .
- The pyrotechnic system can only p rovide
protection for one collision. If the py rotech­
nic pretens ioners deploy, the pretensioning
sys tem must be rep laced.

\.J ' @ Tips
The pyrotechnic safety belt pretensioners can
only deploy once.
- The safety belt pretensioners do not dep loy
in minor fronta l, side and rear-end co lli­
sions.
- A fine dust is released when the pyrotechnic
safety be lt pretensioners deploy . This is nor­
mal and is not caused by a fire in the vehi­
cle.
- The relevant safety requirements must be
observed when the veh icle or components
of the system are scrapped. A qualified
dealersh ip is familiar with these regulations
and will be p leased to pass on the informa­
tion to you.
- Be sure to observe all safety, environmental
and other regulations if the veh icle or indi­
v idual parts of the system, particularly the
safety be lt o r airbag, are to be disposed. We
recommend yo u have your author ized Audi
dealer perform this serv ice for you.
Service and disposal of safety belt preten­
sioner
The safety belt pretens ioners are parts of the
safety belts on your Audi. Installing, removing,
servicing or repa iring of belt pretensioners can
damage the safety belt system and prevent it
from wor king cor rectly in a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment.
& WARNING
Improper care, servicing and repa ir proce­
dures can increase the risk of personal injury
and death by preventing a safety be lt preten­
sioner from activating when needed or acti­
vating it unexpectedly :
- The be lt pretensioner system can be act ivat­
ed only once. If belt pretensioners have
been activated, the system must be re­
placed.
S afet y be lts
- Never repair, adjust, or change any parts of
the safety belt system .
- Safety belt systems including safety belt
pretensioners cannot be repaired. Special
procedures are required for removal, instal­
lation and disposal of this system.
- For any work on the safety belt system, we
strong ly recommend that you see your au­
thor ized Audi dealer or qualified techn ician
who has an Audi approved repa ir manual,
tra ining and special equipment necessary .
@) For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­

Important information
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints . For
airbags to do their job, occupants must always
properly wear their safety belts and be in a prop ­
er seating position.
For your safety and the safety of your passen­
ge rs , before driving off, always :
"' Adjust the driver's seat and steering wheel
properly ¢
page 130,
"'Adjust the front passenge r's seat properly
¢ page 48,
"'Wear safety belts p roperly ¢ page 142 ,
"'Always properly use the proper child restraint
to protect children
¢ page 172.
In a coll is io n, airbags mus t inflate within the
blink of an eye and wi th considerab le force. The
supp lemental airbags can cause injuries if the
driv er or th e front s eat passeng er is not s eated
properly. Therefore in order to he lp the airbag to
do its job, it is important, both as a dr iver and as
a passenger to sit properly at all t imes.
By keeping room between your body and the
steering whee l and the front of the passenger
compartment, the a irbag can inflate fully and
completely and provide supplemental protect ion
in certain frontal collisions¢
page 130, Correct
passenger seating positions .
For details on the
operation of the seat adjustment con trols
¢ page 48.
It's especially important that children are proper ­
ly restra ined
¢ page 172 .
There is a lot that the driver and the passengers
can and must do to help the ind iv idual safety fea­
tures installed in your Audi work together as a
system .
Proper seating posit ion is important so that the
front airbag on the drive r side can do its job. If
you have a physical impairment or cond ition that
prevents you from s itting properly on the driver
seat with the safety be lt properly fastened and
148
reaching the peda ls, or if yo u have concerns w ith
regard to the function or operation of the Ad­
vanced Airbag System, please contact your a u­
thori zed Audi dea ler or qua lified workshop, or
ca ll Audi Customer Relations at 1-800-822-2834
for poss ib le modifications to your vehicle .
When the airbag system dep loys, a gas generator
will fill the airbags, break open the padded cov­ ers, and infla te between the steering wheel and
the driver and between the instrument panel and
t h e front passenger . T he a irbags w il l deflate im­
med iate ly after deployment so that the front oc­
cupants can see t hrou gh the windsh ie ld again
without i nterruption.
All of th is takes p lace in the b link of an eye, so
fast that many people don't even rea lize that the
a irbags have deployed. The airbags a lso infla te
with a g re at deal of force and nothing should be
i n the ir way when they deploy. Front airbags in
combination with properly worn safety belts slow
down and limit the occupant 's forward move­
ment . Together they he lp to prevent the driver
and front seat passenger from hitting pa rts of
the ins ide of the vehicle while reduc ing the fo rces
acting on the occupant dur ing the cras h. In th is
way they help to reduce the risk of injury to the
head and uppe r body i n the crash . Airbags do not
protect the arms or the lower pa rts of the body.
Both front airbags will not inflate in all frontal
collisions . The t riggering of the a irbag system de­
pends on the veh icle decelerat ion rate caused by
t h e coll is io n and regis tered by the ele ctroni c con­
tro l unit . If this ra te is be low the refe rence value
programmed in to the contro l unit, the airbags
will not be trigge red, even tho ugh the car may be
badly damaged as a resu lt of the collision. Vehi­
cle damage, rep air costs or even the lack of vehi­
cle damage is not necessarily an indication of
whether an a irbag should inflate or not .
Since the circumstances will vary cons iderab ly
between one co llision and another, it is not possi ­
ble to define a range of veh icle speeds that will
cover every poss ible kind and angle of impact
that w ill always t rigger t he a irbags . Important
factors i nclude, for examp le, the nat ure (hard or
soft) of the object which the ca r hits, the angle of
i mp act , vehicle speed , etc. The front airbags will .,.
