Never change or replace the bumper or bon
net as a part of tuning measures. This can
impair the effectiveness of the pedestrian
protection system and invalidate the oper
ating permit for your vehicle.
- False activation of the pedestrian protection
system is possible.
Servicing the pedestrian protection system
Applies to: vehicles with pedestrian protection system
Fig. 187 Pressing back/checking the bonnet
If the pedestrian protection system has been de
ployed, the bonnet will be slightly raised at the
end next to the windscreen. In addition, the indi
cator lamp m will be displayed along with a
message .
.,. To engage the bonnet again, press it down with
both hands on the left side of the vehicle in
area (i)¢Fig.187 ¢.&,. .
.,. To check whether the bonnet is properly engag
ed, pull the rear edge of the bonnet @ up
wards. If the bonnet can be lifted, press it
down again .
.,. When the bonnet has engaged properly, repeat
the procedure on the right side of the vehicle .
.,. Drive to the nearest qualified workshop without
delay and have the pedestrian protection sys
tem serviced ¢(D.
8_ WARNING
- Do not press back the bonnet unless both of
your hands are flat on top of the bonnet. If
you do this, you cannot catch your fingers
between the bonnet and body. Take care
when pressing back the bonnet: careless or Safe
driving
uncontrolled movements can cause injury to
yourself or others -risk of injury!
- The system can only be activated once. If
the pedestrian protection system has been
triggered, have it replaced without delay by
a qualified workshop.
CD CAUTION
- All repairs to the bumper and the pedes
trian protection system must only be carried
out by a qualified workshop working to the
specifications of the Audi factory. Improper
repairs can impair the effectiveness of the
system and invalidate the operating permit
for your vehicle.

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. 188 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. 188. 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 230, 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-
230 ner".
Please also ensure that your passenger's
seat belt is properly fastened ¢ 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 ¢ page 231, Forces acting in a
collision.
For information on how children can travel safely
in the car refer to¢ page 223, Child seats.
_& WARNING
- Seat belts must be put on before every trip -
even when driving in town. This also applies
to 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 233, 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.
_& WARNING
- The seat belts can only provide maximum
protection if the seats are adjusted properly
¢ page 54, Front seats.
- To ensure proper protection, it is important
to wear the seat belts in the correct position
¢ page 232, 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.

CX) -
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 265.
- 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 Seat
belts
The physical principles involved in a frontal
impact
Very large forces are generated during a colli
sion; these forces have to be absorbed.
Fig. 189 Passengers of a vehicle which is headed for a
brick wall. They are not using seat belts.
Fig. 190 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. 189. 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. 190. This would
result in serious or potentially fatal injury.
..,.

belts
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 (1,000 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.
Fig. 191 A driver not wearing a seat belt can be thrown
forwards
In a frontal collision, unbelted passengers will be
thrown forwards and make violent contact with
the steering wheel, dashboard, windscreen, etc
¢ Fig. 191. 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.
232 How
to wear seat belts
properly

WARNING
-Always make certain that the belt is posi
tioned properly ¢ Fig. 192 -risk of injury
¢ page
233, 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. 194 Adjusting shoulder/lap belt
The following equipment is available for your ve
hicle to help you position the seat belt properly
to suit your height:
- Height-adjustable seats
- Belt guide ring on backrest
A 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. 194.
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
- 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.

ID
The seat belts are equipped with belt tensioners.
Pyrotechnic belt tensioners
The seat belts are tensioned automatically in se
vere collisions, depending on the circumstances.
This helps to reduce the forward motion of the
occupants.
A WARNING
- False activation of the belt tensioner 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 belt tensioners can only be activated
once. If they have been activated at any
time, the system must be replaced.
Q) Note
- Some smoke may be released when the belt
tensioners are activated. This does not
mean there is a fire in the vehicle.
- The relevant safety requirements must be
observed when the vehicle or components
234 of
the system are scrapped. Your authorised
dealer is familiar with these regulations and
will be pleased to pass on the information
to you.

CX) 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 seat belts, the airbag sys
tem gives the front occupants additional protec
tion for the head and chest in the event of a se
vere frontal collision.
In a severe side collision the side airbags reduce
the risk of injury to the occupants ¢,&..
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 indicator lamp m 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 two side airbags
- The indicator lamp El 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 Airbag
system
this reason it is very important to wear the
seat belts at all times ¢ page 230, 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 54, 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 any way.
- Never make any alterations to the front
bumper or the body.
- Do not remove the 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 deac
tivated, it is important that the new owner
is also given the relevant documents.

system
- The relevant safety requirements must be
observed when the vehicle or components
of the airbag or belt tensioner systems are
scrapped.
- For safety reasons, the alternator and the
starter are both disconnected from the bat
tery via a pyrotechnic circuit breaker in se
vere accidents.
- Any repairs to the pyrotechnic circuit
breaker must always be performed by a
qualified workshop -risk of accident!
- The relevant safety requirements must be
observed when the vehicle or the circuit
breaker 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.
({D 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.

CX) Deactivating
the passenger's airbag
Applies to: vehicles with key-operated switch for passenger's
airbag
If an airbag has been deactivated, it should be
reactivated as soon as possible so that it can
continue to give the required protection.
Fig. 199 Glove box: Key-operated switch for deactivating
passenger's airbag
Fig. 200 Warning lamp lights up when passenger's airbag
is deactivated
If you install a rearward-facing child seat on the
passenger's seat you must deactivate the pas
senger's airbag beforehand .
... To deactivate the passenger's airbag, use the
emergency key to turn the key-operated switch
to OFF ¢ Fig. 199 .
... The
passenger's airbag can be reactivated by
turning the key to position ON.
Monitoring of airbag system
The indicator lamp JJI ¢ page 16 will light up for
a few seconds every time the ignition is switched
on.
If the passenger's airbag has been deactivated,
the indicator lamp "PASSENGER AIR BAG OFF
or" AIR BAG OFF" will light up constantly as a
reminder¢ Fig. 200 . Airbag
system
.&_ WARNING
- Never install a rearward-facing child seat on
the passenger's seat unless the passenger's
airbag has been deactivated -this can result
in potentially fatal injuries to the child
¢page 223.
- If you have deactivated the passenger's air
bag, reactivate it as soon as the child seat is
no longer needed so that the airbag can
continue to give the required protection.
- It is the driver's responsibility to ensure that
the key-operated switch is set to the correct
position.

In conjunction with the seat belts, the front air
bags give additional head and chest protection
for the driver and passenger in the event of a se
vere frontal collision <=> A in Important safety
notes on the front airbag system on page 238.
How the front airbags work
When fully inflated, the airbags reduce the risk
of head or chest injury.
Fig. 203 Front airbags in inflated condition
The driver's and passenger's airbag are triggered
in certain frontal collisions c:> Fig. 203. Further
airbag systems may also be triggered, depending
on the circumstances.
When the system is triggered, the airbags fill
with a propellant gas and open out in front of the
driver and passenger<=> Fig. 203. In order to pro
vide the desired extra protection in an accident,
the airbags have to inflate extremely rapidly
(within fractions of a second). The fully deployed
airbags cushion the forwards movement of the
front occupants and help to reduce the risk of in
jury to the head and the upper part of the body.
Special openings in the airbag allow the gas to
escape at a controlled rate to restrain the for
ward movement of the occupant's head and tor
so. Once the impact has been absorbed, the air
bag deflates sufficiently for the front occupants
to see forward.
238 Important
safety notes on the front airbag
system
There are a number of safety points concerning
the airbag system which you should remember.
This will help to reduce the risk of injury in an ac
cident.

- It is important for the driver and passenger
to maintain a distance of at least 25 cm
from the steering wheel or dashboard
<=> Fig. 204. The airbag system will not be
able to give the required protection if you sit
too close to the steering wheel or dash
board. There is also a risk of injury if the air
bags are inflated. Additionally, the seat po
sition should always be adjusted to the body
size of the occupant.
- If you do not wear a seat belt, if you lean
forward or to the side, or are not seated cor
rectly while the vehicle is in motion, you are
at greater risk of injury. Should the airbag
system be triggered in an accident there is
an even greater risk of injury.
- Never let a child travel on the passenger
seat without an appropriate restraint sys
tem. If the airbag is triggered in an acci
dent, the child could sustain serious or fatal
injuries c:> page 223, Child seats.
- Child seats in which the child faces the rear
of the car are located directly in the path of
the passenger's airbag if it inflates. In this
case, the child could sustain serious or fatal
injuries if the airbag were to be deployed.
- Applies to vehicles on which the passeng-
er's airbag cannot be deactivated: Do NOT
