too far back. The airbag system and seat belts can only provide
proper protection when the backre
st is in an upright position and
the driver is wearing the seat belt in the correct position. The
further the backrest is tilted back, the greater the risk of injury due
to incorrect positionin g of the belt webbing or an incorrect sitting
position.
•
Adjust the head restraint properly so that it can give maximum
protection.
Correct sitting position for front passenger
The front seat passenger must sit at least 25 cm away
from the dash panel so that the airbag has enough room
to inflate and give maximum protection in an accident.For your own safety and to reduce the risk of injury in the
event of an accident, we recommend adjusting the front
passenger's seat as follows:
– Move the front passenger's seat as far back as possible ⇒ .
– Adjust the backrest to an upright position so that your back remains in contact with the upholstery.
– Adjust the head restraint so that the top of the head restraint is level with the top of your head ⇒page 166 .
– Keep both feet in the footwell in front of the seat.
– Fasten your seat belt correctly ⇒page 173.In exceptional cases you can disable the front passenger's airbag
via the key-operated switch* ⇒page 183 .
For detailed information on how to adjust the front passenger's
seat, see ⇒page 70, “Seats and storage”.
WARNING
A passenger who is not sitting in the correct position or who is not
wearing a seat belt can be fatally injured if the airbag is triggered.•
Adjust the front passenger's seat so there is a distance of at
least 25 cm between your breastbone and the dash panel.
•
Always keep your feet on the fl oor when the vehicle is moving;
never rest them on the instrument panel, out of the window or on
the seat. If you sit in an incorrect position, you increase your risk
of injury in the event of sudden brak ing or an accident. If the airbag
is triggered, you could sustain pote ntially fatal injuries by sitting
out of position.
•
To reduce the risk of injury to the front passenger in the case of
sudden braking or an accident, th e passenger should never travel
in a moving vehicle with the backrest reclined. The airbag system
and seat belt can only provide pr oper protection when the back-
rest is in an upright position and the passenger is wearing the seat
belt in the correct position. The fu rther the backrest is tilted back,
the greater the risk of injury due to incorrect positioning of the belt
webbing or an incorrect sitting position.
•
Always adjust the head rest raints properly for maximum
protection.
Correct sitting position for passengers in the rear
Rear seat passengers should sit upright with both feet on
the floor and wear their seat belts properly whenever the
vehicle is moving.To reduce any risk of injury in the event of sudden braking
or an accident, passengers in the rear seats must observe
the following:

Examples of incorrect sitting positions
Occupants can suffer severe or fatal injuries injuries if
they sit in an incorrect position while the vehicle is
moving.Seat belts can only provide maximum protection if the belt
webbing is positioned correctl y. Sitting out of position
greatly reduces the effectiveness of the seat belts and
increases the risk of injury since the belt webbing is not
worn in the position for which it is designed. The driver is
responsible for the safety of all vehicle occupants, espe-
cially for children.
– Never allow anyone to sit out of position while the vehicle is moving ⇒.The following list shows just some examples of incorrect sitting
positions which can be dangerous to all occupants. The list is not
complete, but will help to make you aware of possible dangers
which can be avoided.
Therefore, whenever the vehicle is moving:•
never stand up in the vehicle,
•
never stand on the seats,
•
never kneel on the seats,
•
never travel with the backrest reclined too far,
•
never lean against the dash panel,
•
never lie down on the rear seat,
•
never sit on the front edge of a seat,
•
never sit sideways,
•
never lean out of the window,
•
never put your feet out of the window,
•
never put your feet on the dash panel,
•
never put your feet on the seat cushion,
•
never ride in the footwell,
•
never travel on a seat with out wearing the seat belt,
•
never climb into the luggage compartment.
WARNING
Sitting out of position increases the risk of severe injuries.•
Sitting out of position exposes the occupants to potentially
fatal injuries: if the airbags inflate they can strike any occupant
who is not in one of th e designed seat positions.
•
Before starting a trip, sit in the correct position and stay in this
position as long as the vehicle is moving. Before every trip, make
sure all passengers are sitting in the correct positions and remain
correctly seated at all times ⇒page 70, “Seats and storage”.
Pedal are aPedal s
The pedals must always be free to move and must never
be obstructed by floor mats or any objects in the footwell.– Make sure that the accelerator, brake and clutch pedals
are not obstructed and can be pressed all the way down
to the floor.
– Make sure that all pedals are able to return freely to their original positions.Only use floor mats which leave the pedal area free and can be
securely fastened in the footwell.
If one of the brake circuits should fail, increased brake pedal travel
will be required to bring the vehicle safely to a stop.

inside. In this case the child wo
uld be unable to get out of the
vehicle without help. This could have fatal consequences.
•
Never allow children to play in or around the vehicle. Always
close and lock the boot lid and all the doors when you leave the
vehicle.
•
Never let passengers ride in the luggage compartment. All
occupants must be properly restrained by the seat belts at all
times ⇒page 170 .Note
•
Air circulation in the vehicle helps reduce fogging of the
windows. Used air escapes through ventilation slots in the rear of
the vehicle. Make sure that these ventilation slots are not
obstructed.
•
Suitable belts for securing loads to the fastening rings* are
commercially available.
Applies to vehicles: with fastening ringsFastening rings
Unsecured loads are a hazard to all vehicle occupants.There are fastening rings in the luggage compartment
which can be used to secure luggage and other objects
⇒ page 78 .
– Use the fastening rings to secure items safely in the luggage compartment ⇒ in “Loading the luggage
compartment” on page 77.During a collision or an accident, even small and light objects can
possess so much energy that they can cause very severe injuries.
The amount of this “kinetic energy” depends on the speed of the vehicle and the weight of the object. The most significant factor,
however, is the speed of the vehicle.
An example: An object weighing 4.5 kg is lying unsecured in the
vehicle. During a frontal collision at a speed of 50 km/h, this object
generates a force corresponding to 20 times its weight. That means
that the effective weight of the object increases to about 90 kg. You
can imagine the severity of the injuries which might be sustained if
this “projectile” strikes an occupant as it flies through the
passenger compartment.
WARNING
If items of luggage or other obje
cts are secured to the fastening
rings with inappropriate or da maged retaining cords, injuries
could result in the event of sudden braking or a collision.•
To prevent pieces of luggage or other objects from flying
forward, always use appropriate retaining cords which are prop-
erly secured to the fastening rings.
•
Never secure a child seat on the fastening rings.

Important safety instructions for 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 accident.
WARNING
•
The seat belts can only provi de maximum protection if the
seats are adjusted properly ⇒page 70, “Seats and storage”.
•
To ensure proper protection, it is important to wear the seat
belts in the co rrect position ⇒page 173, “How to wear seat belts
properly”. Ensure that the seat belts are worn exactly as recom-
mended in this chapter. Belts wh ich are not worn properly can
increase the risk of injury in accidents considerably.
•
Do not allow the seat belt to be come twisted or jammed, or to
rub on any sharp edges.
•
Never allow two passengers (even children) to share the same
seat belt. It is especially dangerou s to place a seat belt over a child
sitting on your lap.
•
Do not wear the belt over hard or fragile objects (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 an d function of the belts.
•
The belts must be kept clean, otherwise the retractors may not
work properly ⇒page 226, “Seat belts”.
•
The slot in the seat belt buckle must not be blocked with paper
or other objects, as this can prev ent the latch plate from engaging
properly.
•
The latch plate of the belt mu st always be engaged in the
correct buckle for that seat, ot herwise the belt will not be fully
effective.
•
Check the condition of the seat bel ts at regular intervals. If you
notice that the belt webbing, fi ttings, retractor mechanism or buckle of any of the belts is da
maged, the belt must be replaced
by a qualified workshop.
•
The seat belts must not be remov ed or modified in any way. Do
not attempt to repair a damaged belt yourself.
•
Seat belts which have been worn in an accident and stretched
must be replaced by a qualified workshop. The belt anchorages
should also be checked.
Forces acting in a collisionThe physical principles involved in a frontal impact
Very large forces are generat ed during a collision; these
forces have to be absorbed.

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 them-
selves but also the other occupants
⇒page 172, fig. 181.
How to wear seat belts properlyPutting on the three-point seat belts
Always fasten your seat belts before driving off.– Adjust the front seat and head restraint correctly before
putting on the seat belt ⇒page 70, “Seats and storage”. – To fasten the belt, take hold of the latch plate and pull it
slowly across your chest and lap ⇒.
– Insert the latch plate into the buckle for the appropriate seat and push it down until it is securely locked with an
audible click ⇒fig. 183.
– Pull the belt to check that it is now securely fastened.
The three-point inertia reel belts are tensioned automatically. The
retractor system gives complete 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 in a
sharp curve.
WARNING
•
Always make certain that the belt is positioned properly
⇒ fig. 182 – risk of injury ⇒page 173, “Adjusting the seat belts”.
•
The latch plate of the belt must always be engaged in the
correct buckle for that seat. Oth erwise 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.

– Press the red button in the seat belt buckle ⇒page 174,
fig. 186. The latch plate will spring out of the buckle.
– Guide the belt back by hand so that it is taken up by the retractor.Belt tensionersHow the belt tensioners work
The seat belts for the driver and front passenger are
equipped with belt tensioners.The seat belts on the front seats are tensioned automatically in
frontal, side and rear-end impacts above a certain degree of
severity. This helps to reduce the forward motion of the occupants.
In a less severe accident, or in the event of a roll-over, the belt
tensioners are not activated.
WARNING
•
Any work on the tensioner system or removal and installation
of system components for other repairs must be performed by a
qualified workshop.
•
The belt tensioners can only be ac tivated once. If they have
been activated at any time, the system must be replaced.Note
•
Some smoke may be released when the belt tensioners are acti-
vated. This does not mean there is a fire in the vehicle.
•
The relevant safety requirements must be observed when the
vehicle or components of the system are scrapped. Your authorised
Audi dealer is familiar with these regulations and will be pleased to
pass on the information to you.

•
The airbag system can only be acti vated once; if the airbag has
been triggered, the system must be replaced. Should the airbag
system or airbag modules have to be replaced, the qualified work-
shop carrying out the replacement will document all details in the
appropriate section of the Service Schedule.
•
If you sell the vehi cle, please remember to pass on the
complete Service Wallet to the ne w owner. If any of the airbags
have been deactivated, it is impo rtant that the new owner is also
given the relevant documents.
•
The relevant safety requiremen ts 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 on th e impact side of the
vehicle are triggered together with the head-protection airbag.
The front airbags, side airbags and one of the head-protection
airbags may be triggered together in certain types of accident. The airbag system is
not triggered in minor frontal or side collisions,
or in rear collisions or if the ca r 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 syst ems 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.

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 an d front passenger to maintain a
distance of at least 25 cm from the steering wheel or dashboard
⇒ page 179, fig. 190. The airbag system will not be able to give the
required protection if you sit to o close to the steering wheel or
dashboard. There is also a risk of injury if the airbags are inflated.
The front seats and head restra ints 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 fr ont seat without an appropriate
restraint system. If the airbag is triggered in an accident, the child
could sustain serious or fatal injuries ⇒page 185, “Child safety”.
•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the fr ont passenger's airbag has been deactivated. However, if you have no alternative but to use a rear-
ward-facing child seat on the fr
ont passenger's seat, the front
passenger's airbag must be deac tivated beforehand by means of
the key-operated switch* ⇒page 183. Failure to observe this
precaution could result in serious or potentially 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 obstru ct 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 ho lders 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) must 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 183 .

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 airbags be triggered in an accident.
•
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. This could result in serious or potentially fatal injury
⇒ page 185, “Child safety”.
•
It is 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 lo cated in the front doors. You
must therefore not make any modi fications 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 ca rried out by a qualified work-
shop.
•
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heav y or sharp-edged objects in the
pockets.
•
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 fa il to operate when required.
•
If you intend to fit protective co vers 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 ba
ckrest, and seriously reduce the
airbag's ef fectiveness.
•
Any damage to the original seat upholstery or around the
seams of the side airbag units mu st 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) must al ways be performed by a qualified
workshop. Otherwise the airbag system may fail to work
properly.
Head-protection airbags (sideguard)Description of head-protection airbags
The head-protection airbags work together with the side
airbag system to give extra protection in a side impact.The head-protection airbags are located above the doors on the left
and right sides of the vehicle ⇒fig. 193. The locations of the airbags
are marked with the word “AIRBAG”.

•
The sensors for the airbags are lo cated in the front doors. You
must therefore not make any modi fications 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 ca rried out by a qualified work-
shop.
•
Where sun blinds are fitted on th e rear doors, these must not
obstruct or impair the airbags in any way.
•
If unsuitable accessories are installed near the head-protection
airbag, the protection afforded by the airbag can be seriously
impaired if the system is triggered. When the head-protection
airbag opens, parts of these accessories coul d be thrown into the
vehicle and inju re passengers ⇒page 250 .
•
Any work involving the head-protection airbags, or removal
and installation of the airbag components for other repairs (such
as repairs to the roof liner), must always be performed by a quali-
fied workshop. Otherwise the airbag system may fail to work
properly.
Applies to vehicles: with key-operated switch for front passenger's airbagDeactivating the front passenger's airbag via the key-operated switchIf an airbag has been deactivated, it should be reactivated
as soon as possible so that it can continue to give the
required protection.The key-operated switch for deactivating the front
