Seat belts
Why is it so important to
use seat belts?
Seat belts provide effective protection
The common belief that passengers can brace
their weight with their hands in a minor collision
is false.

Fig.
215 Driver with correctly positioned seat belt - good
protection if the brakes are applied suddenly
It is an established fact that seat belts provide
good protection in accidents. Therefore wearing
a seat belt is required by law in most countries.
When worn correctly, seat belts hold the occu­
pants in the best position for maximum protec­
tion
^>Fig.
215. The seat belts are capable of ab­
sorbing much of the kinetic energy which is
gen­

erated in a collision. They also help to prevent
uncontrolled movements which could Lead to se­
vere injuries
^>page
275, Important safety
notes when using seat belts.
If they wear the seat belts correctly, the passen­
gers benefit greatly from the ability of the belts
to reduce the kinetic energy gradually. The front
crumple zones and other passive safety features
(such as the airbag system) are also designed to
absorb the kinetic energy generated in a
colli­

sion.
Taken together, all these features reduce
the forces acting on the occupants and conse­
quently the risk of injury.
Although these examples are based on a frontal

collision,
the physical principles involved are the
same in other types of accidents. This is why it is
so important to put on the seat belts before ev­
ery trip - even when "just driving around the cor­
ner". Ensure that your passengers wear their seat
belts as well
^A-

Seat belts worn correctly have been shown to be
an effective means of reducing the potential for
injury and improving the chances of survival in a
serious accident

collision.

in the car refer to

267, Child seats.
A WARNING
- Seat belts must be put on before every trip -
even when driving in town. This also applies
to the rear passengers - risk of injury!
- During pregnancy, women should always
ensure they wear a seat belt. The best way
to protect the unborn child is to protect the
mother
^>page
278, Wearing and adjust­
ing the seat belts during pregnancy.
Important safety notes when using seat
belts
There are a number of safety points concerning
the seat belts which you should remember. This
will help to reduce the risk of injury in an
acci­

dent.
A WARNING
- The seat belts can only provide maximum
protection if the seats are adjusted properly

^>page
58, Front seats.
- To ensure proper protection, it is important
to wear the seat belts in the correct position

^>page
277, How to wear seat belts prop­

erly.
Ensure that the seat belts are worn ex­
actly as recommended in this chapter. Belts
which are
not
worn properly can increase
the risk of injury in accidents considerably.
- Do not allow the seat belt to become twis­
ted or jammed, or to rub on any sharp
edges.
- Never allow two passengers (even children)
to share the same seat belt. It is especially
dangerous to place a seat belt over a child
sitting on your lap.
275

Seat belts
- Do not wear the belt over hard or fragile ob­
jects (such as glasses or pens, etc.) because
this can cause injuries.
- Loose, bulky clothing (such as an overcoat
over
a
jacket) impairs the proper fit and
function of the belts.
- The belts must be kept clean, otherwise the
retractors may not work properly

•=>
tab. Cleaning the interior on page 314.
- The slot in the seat belt buckle must not be
blocked with paper or other objects, as this
can prevent the latch plate from engaging
properly.
-The latch plate of the belt must always be
engaged in the correct buckle for that seat,
otherwise the belt will not be fully effective.
- Check the condition of the seat beLts at
reg­

ular intervals. If
you
notice that the belt

webbing,
fittings, retractor mechanism or
buckle of any of the belts is damaged, the
belt must be replaced by a qualified work­

shop.

- The seat belts must not be removed or
modified in any way. Do not attempt to re­
pair
a
damaged belt yourself.
- Seat belts which have been worn in an
acci­

dent and stretched must be replaced by a
qualified workshop. The belt anchorages
should also be checked.
Forces acting in a
collision
The physical principles involved in a frontal
impact

Very
large forces are generated during a
colli­

sion; these forces have to be absorbed.

Fig.
216 Passengers of
a
vehicle which is headed for a
brick
wall.
They are not using seat belts.

Fig.
217 The vehicle crashes into the wall
The physical principles involved in a frontal
colli­

sion are relatively simple:
Both the moving vehicle and the passengers pos­
sess energy, which is known as "kinetic energy"

^>Fig.
216. The amount of "kinetic energy" de­
pends on the speed of the vehicle and the weight
of the vehicle and passengers. The higher the
speed and the greater the weight, the more ener­
gy there is to be absorbed in an accident.
The most significant factor, however,
is
the
speed of the vehicle. If the speed doubles from
25 km/h to 50 km/h, for example, the kinetic en­
ergy increases by
a
factor of four. Because these
passengers are not restrained by seat belts, the
entire amount of kinetic energy has to be absor­
bed
at
the point of impact
^>Fig.
217. This would
result in serious or potentially fatal injury.

Even
at
urban speeds
of
30 km/h to 50 km/h, the
forces acting on the occupants in a collision can
reach the equivalent
of
1 ton (1000 kg)
or
more.
At greater speed these forces are even higher.

Again:
if
the speed doubles, the forces increase
by
a
factor of four.
Passengers who do not wear seat belts are not

"attached"
to the vehicle. In a frontal collision
they will continue to move forward at the speed
their car was travelling just before the impact.
What happens to passengers not wearing
seat belts?

Passengers
not wearing seat belts risk fatal inju­
ries in the event
of
an
accident.

In a frontal collision, unbelted passengers will be
thrown forwards and make violent contact with
the steering wheel, dashboard, windscreen, etc

^Fig.
218. Passengers not wearing their belts
risk being thrown out of the car. This could result
in potentially fatal injuries.
The common belief that occupants can brace
their weight with their hands in a minor collision
is false. Even
at
low speeds the forces acting
on

the body in a collision are so great that
it
is not
possible to hold yourself in the seat.
It is also important for the rear passengers
to

wear seat belts, as they could otherwise be
thrown forwards violently in an accident. Rear
passengers who do not use seat belts endanger
not only themselves but also the other occupants

Seat belts

•
Pull the belt to check that it is now securely fas­

tened.

The three-point inertia reel belts are tensioned
automatically. The retractor system gives com­
plete freedom of movement, as long as the pull
on the belt is slow. Hard braking locks the belt.
The belt will also lock when you accelerate, drive
up or down a steep hill or corner sharply.
A WARNING
- Always make certain that the belt is
posi­

tioned properly
^>Fig.

<=$page
278, Adjusting the seat belts.
- The latch plate of the belt must always be
engaged in the correct buckle for that seat.
Otherwise the belt will not be fully effective
and the danger of injury increases.
Adjusting the seat belts
Always position seat belts properly for maximum
safety.

Fig.
222 Adjusting shoulder/lap belt
The following features allow you to match the
position of the seat belt to your height:
- Belt height adjustment*
- Seat height adjustment (front seats)

/K WARNING

- The shoulder section of the belt should be
fitted across the centre of the collar bone
close to the body. To fasten the belt, take
hold of the belt above the latch plate and
pull it slowly down across your chest. Wear
the lap portion of the seat belt as low as
possibLe over the hips so that there is no
pressure on the lower abdomen. The belt
should always be worn tightly
^>Fig.
222.
Pull the belt tight if necessary to take up
any slack.
-Always make sure that belt is positioned
properly. Incorrectly worn seat belts can
give rise to injuries even in a minor coLlision.
- Seat belts worn too loose can result in
inju­

ries because they allow excessive forward
movement in a crash; the occupant will be
brought to a sudden stop by the belt web­

bing.

Wearing and adjusting the seat belts
during pregnancy

To
afford the best protection for the unborn
child it is important for the mother to wear the
seat belt properly at all times.

Belt tensioners

Reversible
belt tensioners*
The following functions are available when seat
belts with reversible belt tensioners are buckled:
- The seat belts can be tensioned reversibly in
certain situations
^>page
120.
- The seat belts can be also be tensioned reversi­
bly in light collisions.
Pyrotechnic belt tensioners*
Seat belts with pyrotechnic belt tensioners are
tensioned automatically in severe collisions, de­
pending on the circumstances. This helps to re­
duce the forward motion of the occupants.

A,
WARNING
- False activation of the
belttensioner
is pos­

sible.

- Any work on the tensioner system or remov­
al and installation of system components
for other repairs must be performed by a
qualified workshop.
- The pyrotechnic system can only be activa­
ted once. If the pyrotechnic belt tensioners
have been activated at any time, the system
must be replaced.

Airbag system
Airbag system
Description of airbag
system
General notes on airbag system
The airbag is an integral part of the car's passive
safety system.
In conjunction with the three-point seat belts,
the airbag system gives the front occupants
addi­

tional protection for the head and chest in the
event of a severe frontal collision.
In a severe side collision the side airbags and the
head-protection airbags reduce the risk of injury
to the occupants
•=>
A-
In addition to their normal function of protecting
the occupants in a collision, the seat belts also
hold them in a position where the airbags can in­
flate properly and provide maximum protection.
The airbag system will only work with the
igni­

tion on. The airbag system is monitored electron­
ically; the airbag warning lamp indicates whether
the system is functioning properly.
The main parts of the airbag system are:
-The electronic monitoring system (control unit
and sensors)
- The two front airbags
- The front side airbags
-The head-protection airbags
- The indicator Lamp
Q
in the instrument cluster
There is a fault in the airbag system if the
warning lamp
- does not come on when the ignition is switched

on.

- does not go out about 4 seconds after the
igni­

tion is switched on.
- goes out and then comes on again after the ig­
nition is switched on.
- comes on or flickers while the car is moving.

A WARNING
- The airbags are not a substitute for the seat

belts;
they are an integral part of the car's
overall passive safety system. The airbags
can only offer effective protection if the oc­
cupants are wearing their seat belts. For
this reason it is very important to wear the
seat belts at all times
^>page
275, Why is it
so important to use seat belts?.
The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly
^>page
58, Front seats.

•
If you do not wear a seat belt, if you lean

forward,
or are not seated correctly while
the vehicle is in motion, you are at greater
risk of injury should the airbag system be
triggered in an accident.
Components of the airbag system are loca­
ted in various parts of the vehicLe. If repairs
to other vehicle components make it neces­
sary to perform work on the airbag system
or to remove or install parts of the airbag

system,
this may cause damage to the air-
bag system. As a result, the airbags may not
inflate correctly or may not be triggered at
all in an accident situation. For this reason,
you should always have the work carried out
by a qualified workshop.
If a fault should occur in the airbag system,
have the system checked immediately by a
qualified workshop. Otherwise the system
may fail to trigger in an accident.
Do not attempt to modify components of
the airbag system in
anyway.

Never make any alterations to the front
bumper
or
the body.
Do not remove the front seats.
The airbag system can only be activated

once;
if the airbag has been triggered, the
system must be replaced. Should the airbag
system or airbag modules have to be re­

placed,
the qualified workshop carrying out
the replacement will document all details.

•
If any repair work is required
or
the airbag
and restraint systems have to be replaced,
have the work carried out by your authorised
Audi dealer or a qualified workshop which
adheres to the Audi factory standards. This
will minimise the risk of injury.
If you sell the vehicle, remember to pass on
the complete Service Wallet to the new
owner. If any of the airbags have been
281

Airbag system
deactivated, it is important that the new
owner is also given the relevant documents.
- The relevant safety requirements must be
observed when the vehicLe or components
of the airbag or belt tensioner systems are

scrapped.

When are the airbags triggered?
One or more airbag systems are triggered in se­
vere collisions, depending on the circumstances.
Factors determining the triggering response
It is not possible to define the exact triggering
response of the airbag system in all possible sit­
uations, since the circumstances in different
types of accident will vary considerably. Impor­
tant factors include, for example, the nature
(hard or soft) of the object which the car hits, the
angle of impact, vehicle speed and so on.
Whether the airbags are triggered depends
pri­

marily on the vehicle deceleration rate resulting
from the collision. By processing the signals from
the sensors Located in the vehicLe, the electronic
control unit is immediately able to evaluate the
severity of the collision and activate the restraint
systems accordingly. If the deceleration rate is
below the predefined reference value in the
con­

trol unit the airbags will not be triggered, even
though the accident may cause extensive damage
to the car. In these situations, the occupants are
protected by wearing the seat belts.

Note

The airbag may release a fine dust when it in­

flates.
This is quite normal and does not
mean there is a fire in the vehicle.
