If you sell the vehicle, please remember to pass on the
complete Service Wallet to the new owner. If the front passenger's
airbag has been 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.
•
In an accident in which one or more airbags are triggered the
alternator and the starter are - for safety reasons - both discon-
nected from the battery via a pyrotechnic circuit breaker.
−Any repairs to the pyrotechnic circuit breaker must always
be performed by a qualified workshop (accident risk).
−The relevant safety requirements must be observed when
the vehicle or the circuit breaker are scrapped.
When are the airbags triggered?
The airbag system is triggered in collisions with a severe
impact.The airbag system is designed so that the airbags for the driver and
front passenger are triggered in a severe frontal collision.
In severe side collisions the side airbags are triggered on the impact
side of the vehicle.
In certain types of accident the front airbags and the side airbags
may be triggered together.
The airbag system is not triggered in minor frontal or side collisions,
or in rear collisions or if the car overturns. In these situations the
occupants are protected by wearing the seat belts.
Factors determining the triggering response
It is not possible to define the exact triggering response of the
airbag system in all possible situations, since the circumstances in different types of accident will vary considerably. Important 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 primarily 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 colli-
sion and activate the restraint systems accordingly. If the decelera-
tion rate is below the predefined reference value in the control unit
the airbags will not be triggered, even though the accident may
cause extensive damage to the car.
Note
The airbag releases a fine dust when it inflates. This is quite normal
and does not mean there is a fire in the vehicle.Front airbagsDescription of front airbags

Technical data The front airbag for the driver is located in the padded hub of the
steering wheel ⇒page 116, fig. 95. The front airbag for the front
passenger is in the dashboard above the glove box ⇒fig. 96. The
locations of the airbags are marked with the word “AIRBAG”.
In conjunction with the three-point seat belts, the front airbags give
additional head and chest protection for the driver and front
passenger in the event of a severe frontal collision ⇒ in “Impor-
tant safety notes on the front airbag system” on page 117.
How the front airbags work
When fully inflated, the airbags reduce the risk of head or
chest injury.
The airbag system is designed so that the airbags for the driver and
front passenger are triggered in a severe frontal collision.
In certain types of accident the front airbags and the side airbags
may be triggered together.
When the system is triggered, the airbags fill with a propellant gas
and open out in front of the driver and front passenger ⇒fig. 97. In
order to provide 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 move-
ment of the front occupants and help to reduce the risk of injury 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 forward movement of the occupant's
head and torso. Once the impact has been absorbed, the airbag
deflates sufficiently for the front occupants to see forward.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 accident.

WARNING
•
It is important for the driver and front passenger to maintain a
distance of at least 25 cm from the steering wheel or dashboard
⇒page 117, fig. 98. The airbag system will not be able to give the
required protection if you sit too close to the steering wheel or
dashboard. There is also a risk of injury if the airbags are inflated.
The front seats and head restraints must always be positioned
correctly for the height of the occupant.
•
If you do not wear a seat belt, if you lean forward or to the side,
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 there is an even greater risk of injury.
•
Never let a child travel on the front seat without an appropriate
restraint system. If the airbag is triggered in an accident, the child
could sustain serious or fatal injuries ⇒page 122, “Child safety”.
•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been
deactivated. However, if you have no alternative but to use a rear-
ward-facing child seat on the front passenger's seat, the front
passenger's airbag must be deactivated beforehand by means of
the key-operated switch ⇒page 120, “Deactivating the airbags”.
Failure to observe this precaution could result in serious or poten-
tially fatal injury.
•
Occupants sitting in the front of the car must never carry any
objects or pets in the space between them and the airbags, or
allow children or other passengers to travel in this position.
•
Do not cover or stick anything on the steering wheel hub or the
soft plastic surface of the airbag unit on the passenger's side of
the dashboard, and do not obstruct or modify them in any way.
These parts should only be cleaned with a dry cloth (or with a
cloth moistened with plain water). It is also important not to
attach any objects such as cup holders or telephone mountings to
the surfaces covering the airbag units.
•
Any work on the airbag system or removal and installation of
the airbag components for other repairs (such as repairs to the
steering wheel) should be performed by a qualified workshop.Note
If necessary, you can deactivate the front passenger's airbag by
means of the key-operated switch ⇒page 120, “Deactivating the
airbags”.Side airbagsDescription of side airbags

on page 119.
In a side collision the side airbags reduce the risk of injury to the
areas of the body facing the impact.
How the side airbags work
When fully inflated, the side airbags reduce the risk of
head or chest injury.In certain types of side collisions the side airbag is triggered on the
impact side of the vehicle ⇒fig. 100.
In certain types of accident the front airbags and the side airbags
may be triggered together.

Important safety notes on the side 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 accident.
WARNING
•
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 side airbag system be triggered in an acci-
dent.
•
If children are not seated correctly, they are at greater risk of
injury in an accident. This is particularly the case if the child is
travelling on the front passenger's seat and the airbag system is
triggered in an accident. This could result in serious or potentially
fatal injury ⇒page 122, “Child safety”.
•
It is also important not to attach any accessories (such as cup
holders) to the doors. This would impair the protection offered by
the side airbags.
•
The sensors for the airbags are located in the front doors. You
must therefore not make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers), as this could impair the func-
tion of the side airbags. Any damage to the front doors could lead
to faults in the system. Repairs or any other work on the front
doors must therefore always be carried out by a qualified work-
shop.
•
Do not apply excessive force to the sides of the backrests (such
as hard knocks or kicks), as this could damage parts of the system.
The side airbags could then fail to operate when required.
•
If you intend to fit protective covers over the seats, these must
be of the specific type approved for use on Audi seats with side
airbags. Conventional seat covers would obstruct the side airbag
when it inflates out of the backrest, and seriously reduce the
airbag's effectiveness.

Any damage to the original seat upholstery or around the
seams of the side airbag units must be repaired immediately by a
qualified workshop.
•
Any work involving the side airbag system or removal and
installation of the airbag components for other repairs (such as
repairs to the seats) should always be performed by a qualified
workshop. Otherwise the airbag system may fail to work
properly.
Deactivating the airbagsDeactivating airbags
If airbags have been deactivated, they should be reacti-
vated as soon as possible so that they can continue to
give the required protection.There are two ways of deactivating the airbags: you can deactivate
the front passenger's airbag yourself by means of the key-operated
switch ⇒page 120. The other airbags can be deactivated by your
Audi R8 dealer.
Deactivating front passenger's airbag when a child
safety seat is in use
If you have no alternative but to install a rearward-facing child safety
seat on the front passenger's seat you must deactivate the front
passenger's airbag beforehand.
Monitoring of airbag system
The airbag warning lamp will light up for a few seconds every time
the ignition is switched on.
WARNING
•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been
deactivated – this can result in potentially fatal injuries to the child
⇒page 123.

Child safety 122Child safetyPoints to remember if children are
travelling in the carIntroductionThe physical principles involved and the forces acting in a collision
apply to children just as much as adults ⇒page 110, “Forces acting
in a collision”. But, unlike adults, children do not have fully devel-
oped muscle and bone structures. This means that children are
subject to a greater risk of injury.
To reduce this risk, children must always use special child restraint
systems when travelling in the car.
Use only child restraint systems which are officially approved under
the European standard ECE R 44 and are suitable for the child. ECE R
refers to the Economic Commission of Europe Recommendation,
which categorises child restraint systems in 5 groups ⇒page 123,
“Child seat categories”. Child restraints that have been tested and
approved under the ECE R 44 standard bear the ECE-R 44 test mark
on the seat (the letter E in a circle with the test number below it).
We recommend using child restraint systems from the range of
Audi Genuine Accessories available from Audi R8 dealers. The
“Huckepack” range includes suitable restraint systems for all ages.
These systems have been specially designed for use in Audi vehicles
and comply with the ECE R 44 standard.
Follow the manufacturer's instructions and observe any statutory
requirements when installing and using child restraints ⇒ in
“Important safety notes for using child safety seats”.
Important safety notes for using child safety seats
Correct use of child safety seats can help to reduce the
risk of injury in an accident.
WARNING
•
All vehicle occupants, especially children, must wear a seat
belt while the vehicle is in motion.
•
Children who are less than 1.5 metres tall must not wear a
normal seat belt without a child restraint, as this could cause inju-
ries to the abdominal and neck areas.
•
Babies and children must never travel on another occupant's
lap.
•
A suitable child safety seat can protect your child ⇒page 123,
“Child safety seats”.
•
Never allow two children to occupy one child safety seat.
•
Never leave a child without supervision in a child safety seat.
•
Never allow a child to travel in the car without a suitable child
restraint.
•
Never allow a child to stand up or kneel on a seat while the car
is moving. In an accident, the child could be catapulted through
the car, causing possibly fatal injuries to itself and other occu-
pants.
•
If children lean forward or are otherwise out of position when
the car is moving, they are at greater risk of injury in an accident.
This is especially the case if the airbag is activated during an acci-
dent. There is then a risk of serious or potentially fatal injury.
•
To ensure proper protection, it is important to wear the seat
belts in the correct position ⇒page 112, “How to wear seat belts
properly”. Always check that the belt is properly positioned

Technical data according to the instructions provided by the manufacturer of the
child safety seat. Incorrectly worn seat belts can give rise to inju-
ries even in a minor collision.
•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been
deactivated.
•
Extra caution is advised if you are installing a child safety seat
using the same mounting bolts as the existing car seat belts. The
bolts must be screwed in all the way to the full depth of the
mounting holes and tightened to a torque of 50 Nm. Failure to
observe this precaution could result in potentially fatal injury. We
recommend having the installation performed by a qualified work-
shop.
•
Do not use a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been
deactivated. The child seat would be directly in the path of the
airbag as it inflates, and the child could sustain serious or fatal
injuries if the airbag were to be deployed.
•
However, if you have no alternative but to use a rearward-
facing child seat on the front passenger's seat, the front
passenger's airbag must be deactivated beforehand by means of
the key-operated switch. Failure to observe this precaution could
result in serious or potentially fatal injury.
•
Make sure that the front passenger's airbag is reactivated by
means of the key-operated switch as soon as the child seat is no
longer needed on the front passenger's seat.
•
When using a child safety seat of the type which faces in the
direction of travel, the front passenger's seat must be moved back
to the rearmost position.
Child safety seatsChild seat categories
Only use child restraint systems that are officially
approved and suitable for the child.Child restraint systems are covered by the European standard
ECE R 44 (issued by the Economic Commission of Europe).
The child seats are divided into 5 categories:
Children who are taller than 1.5 metres can use the existing seat
belts without a booster cushion.
Child restraints that have been tested and approved under the ECE
R 44 standard bear the ECE-R 44 test mark on the seat (the letter E
in a circle with the test number below it).
