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 rrectly wear safety be lts
when the vehicle is moving .
- Pregnant women, injured, o r physically im
paired persons must a lso use safety belts.
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 five seating positions:
two in the front and three in the rear. In some
veh icles, there are four seating positions: two in
the front and two in the rear . Each seating posi
tion has a safety belt .
&_ WARNING
Not wea ring safety belts or wearing them im
properly incre ases the risk of ser io us personal
injury and dea th.
- Never st rap more tha n one person, includ
ing small ch ild ren, into any be lt .
It is espe
c ia lly da ngerous to place a safety belt over a
child sitting on your lap .
218
-Never let more people ride in the vehicle
than there are safety be lts available .
- Be s ure 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 to remind you about the importance of buckling-up .

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 . 224. 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 . 22 5 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-
220
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 roll overs or in cases where the re 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!

The safety belts on the front seats a re equipped
with power revers ible tensione rs. The following
funct ions are available whe n the drive r's/front
passenger 's safety belts are faste ned:
- Automatic tens ione rs: at the start of a drive,

infant or a child in a rearward -facing seat.
The Advanced Airbag System i n your veh icle has
been ce rt ified to comp ly with the requirements
of United States Federa l Motor Vehicle Safety
Standard ( FMVSS)
208, as well as Canada Motor
Veh icle Safety Standard (CMVSS)
208 as applica
b le at the time your vehicle was manufactured.
According to requirements, the front Advanced
Airbag System on the passenger s ide has been
certified for "suppression " for infants of about
12 month old and younger and for "low risk de
p loyment " for children aged
3 to 6 years o ld (as
defined in the standard).
The
PA SSENGER AIR BAG OFF light in the instru
ment panel tells you when the front Advanced
Ai rbag on the passenger side has been tu rned off
by the ele ct roni c con trol unit.
Each t ime you sw itch on the ign it ion, the
PAS
SENGER AIR BAG OFF
li ght will come on fo r a
few seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small c hild or child re
straint on the front passenger seat,
- will go off if the front passenger seat is occu
pied by an adult as reg istered by the weight
sensing mat¢
page 236, Monitoring the Ad
vanced Airbag System .
The PASSENGER AIR BAG OFF light comes on
when the control unit detects a tota l we ight on
the front passenger seat that requires the front
a ir bag to be turned off.
If the tota l weight on the front passenger seat is
more than that of a typical 1 year -old child but
less than the we ight of a small adult, the front
a ir bag on the passenger side can deploy (the
PASSENGER AIR BAG OFF ligh t does not come
on) .
If the PASSENGER AIR BAG OFF light does
not come on, the front a irbag on the passenger
side has not been turned
off by the electronic
control unit and can deploy if the control unit
senses an impact that meets the condit ions stor
ed in its memory.
For e xample, the airbag may deploy if:
228
- a small ch ild that is heav ier than a typica l 1
year-o ld child is on the front passenger seat
(regard less of whether the child is in one of the
child seats listed
¢ page 250), or
- a child who has outgrown c hild restraints is on
the front passenger seat.
If the front passenger a irbag is t urned
off, the
PASSENGER AIR BAG OFF light comes on in the
i nstrument cluster and stays on.
The fro nt airbag on the passenge r side m ay
not
deploy (the PASSENGER AIR BAG OFF light does
not ill uminate and stay lit) even if a small adu lt
or teenager, or a passenger who is not sitting up
right with their back against a non-recl ined back
rest with the ir fee t on the vehicle floor in front of
the sea t is on the front passenger seat
<=> page 208 , Proper seating position for the driv
er .
If the front passenger a irbag deploys, the Feder
al Standard requires the airbag to meet the "low
risk" deployment cr iteria to reduce the r isk of in
j ury th rough interaction w ith the airbag . "low
risk" deployment occurs in th ose crashes that
