Safe driving
186Safe drivingGeneral notesSafety is the first priority
Your safety is our first priority.This chapter contains important information, tips, sugges-
tions and warnings that you should read and observe for
your own safety and the safety of your passengers.
WARNING
•
The information in this chapter is important for the driver of
the vehicle and all passengers. Th e other chapters in this manual
(and, where applicable, in the ot her literature supplied with the
vehicle) contain further importan t notes which you should read
and observe for your own safety and that of your passengers.
•
Ensure that the complete vehicle wa llet is always in the vehicle.
This is especially imp ortant when you lend or sell the vehicle to
others.
Safety features
The safety features listed he re are part of the vehicle's
occupant restraint system. They work together to help
reduce the risk of injury in a wide variety of accident situ-
ations.Your safety and the safety of your passengers should not be left to
chance. In the event of an accident, the safety features incorporated
in your vehicle are capable of reducing the risk of injury. These are
just a few of the safety features in your Audi:•
Optimised three-point seat belts for all seats,
•
Belt force limiters for the front seats,
•
Belt pre-tensioners for the front seats,
•
Head restraints for all seats,
•
Optimised protection against injuries of the cervical vertebrae,
•
Front airbags,
•
Side airbags in the front seat backrests and on the outer rear
seats*,
•
Head-protection airbags (sideguard system),
•
“ISOFIX” mountings* for “ISOFIX” child safety seats on the rear
seats,
•
Height-adjustable head restraints on the seats,
•
Adjustable steering column.
These individual safety features are harmonised to provide you and
your passengers with the best possible protection in accident situ-
ations. However, they can only be effective if you and your passen-
gers sit in the correct position and adjust and use the safety equip-
ment properly.
For these reasons, this chapter explains why these safety features
are so important, how they can protect you, what you need to
remember when using them, and how you and your passengers can
gain the most benefit from them. There are also a number of impor-
tant safety warnings which you and your passengers should always
observe in order to minimise the risk of injury.
Safety is everyone's responsibility!

Safe driving
188Correct sitting positionsCorrect sitting position for driver
The correct driving position is important for safe and
fatigue-free driving.For your own safety, and to reduce the risk of injury in the
event of an accident, we re commend the following driving
position.
– Adjust the steering wheel so there is a distance of at least 25 cm between the steering wheel and your breastbone
⇒fig. 199. – Move the driver's seat forwards or backwards so that you
can press the accelerator, brake and clutch pedals all the
way to the floor with your knees slightly bent ⇒.
– Make sure that you can comfortably reach the top of the steering wheel.
– Adjust the head restraint so that the top of the head restraint is level with the top of your head ⇒fig. 200.
– Adjust the backrest to an upright position so that your back remains in contact with the upholstery.
– Fasten your seat belt correctly ⇒page 194 .
– Keep both feet in the footwe ll so that you are in full
control of the vehicle at all times.
For detailed information on how to adjust the driver's seat, see
⇒ page 73, “Seats and storage”.
WARNING
•
A driver 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 driver's seat so there is a distance of at least 25 cm
between your breastbone and th e centre of the steering wheel
⇒ fig. 199.
•
While driving, always hold the steering wheel with both hands
on the outside of the rim at about the 9 o'clock and 3 o'clock posi-
tion. This reduces the risk of injury if the driver's airbag inflates.
•
Never hold the steering wheel at the 12 o'clock position, or
with your hands inside the rim or on the steering wheel hub. This
could result in serious injuries to the arms, hands and head if the
driver's airbag inflates.
•
To reduce any risk of injury to the driver during a sudden brake
application or in an accident, neve r drive with the backrest tilted

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 190 .
– Keep both feet in the footwell in front of the seat.
– Fasten your seat belt correctly ⇒page 197.In exceptional cases you can disable the front passenger's airbag
via the key-operated switch* ⇒page 208 .
For detailed information on how to adjust the front passenger's
seat, see ⇒page 73, “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 73, “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.

Seat belts
194Seat beltsWhy 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.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.
Properly worn seat belts hold the occupants in the best position for
maximum protection ⇒fig. 203. The seat belts are capable of
absorbing much of the kinetic energy arising in a collision. Also they
help to prevent uncontrolled movements which could lead to severe
injuries ⇒page 195, “Important safety instructions for using seat
belts”.
If they wear the seat belts correc tly, the passengers benefit greatly
from the ability of the belts to re duce 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 collision. Taken together, all these features reduce the forces acting on the occupants and consequently the risk of
injury.
Although these examples are based on
a frontal collision, the phys-
ical principles involved are the same in other types of accidents and
for vehicles with an airbag system. This is why it is so important to
put on the seat belts before every trip – even when “just driving
around the corner”. Ensure that your passengers wear their seat
belts as well ⇒.
Properly worn seat belts 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 195, “Forces acting in a colli-
sion”.
For information on how children can travel safely in the car
⇒ page 210, “Points to remember if children are travelling in the
car”.
WARNING
•
Seat belts must be put on before ev ery trip – even when driving
in town. This also applies to th e rear passengers (injury risk).
•
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 198, “Wearing and adjusting the seat belts during
pregnancy”.

Technical data
Airbag systemDescription of airbag systemGeneral notes on airbag system
The airbag is an integral part of the car's passive safety
system.In conjunction with the three-poin t seat belts, the airbag system
gives the front occupants additional 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 in the areas of the
body facing the impact ⇒.
In addition to their no rmal function of protecting the occupants in a
collision, the seat belts also hold them in a position where the
airbags can inflate properly and provide maximum protection.
The airbag system will only work with the ignition on. The airbag
system is monitored electronically; the airbag warning lamp indi-
cates 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 side ai rbags on the outer rear seats*
and the head-protection airbags,
•
the airbag warning lamp 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 ignition is switched
on,
•
goes out and then comes on again after the ignition is switched
on,
•
comes on or flickers while the car is moving.
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 occupants are wearing
their seat belts. For this reason it is very important to wear the
seat belts at all times ⇒page 194, “Why is it so important to use
seat belts?”.
•
The seat belts and airbags can only provide maximum protec-
tion if the occupants are seated correctly ⇒page 73, “Seats and
storage”.
•
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 located in various parts
of the vehicle. If repairs to other vehicle components make it
necessary to perform work on the airbag system or to remove or
install parts of the airbag system, this may cause damage to the
airbag system. As a result, the ai rbags may not inflate correctly or
may not be triggered at all in an a ccident situation. For this reason,
you should always have the work carried out by a qualified work-
shop.
•
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 compon ents of the airbag system in
any way.
•
Never make any alterations to the front bumper or the body.

Airbag system
202•
Do not remove the front seats.
•
The airbag system can only be ac tivated 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 vehicle, please remember to pass on the
complete Service Wallet to the new 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 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 circ uit breaker are scrapped.
When are the airbags triggered?
The airbag system is triggere d 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 the 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 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 situat ions, since the circumstances in
different types of accident will va ry 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
The airbag system is not a substitute for the seat belts.The front airbag for the driver is located in the padded hub of the
steering wheel ⇒fig. 214. The front airbag for the front passenger
is in the dashboard above the glove box ⇒fig. 215. 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 204.
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, side airbags and one
of the head-protection 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. 216.
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 fo rward 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.

Airbag system
204Important 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 th e driver and front passenger to maintain a
distance of at least 25 cm from the steering wheel or dashboard
⇒ fig. 217. 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 th e 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 tr iggered in an accident, the child
could sustain serious or fatal injuries ⇒page 210, “Child safety”.
•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the fron t 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 deac tivated beforehand by means of
the key-operated switch* ⇒page 208 . 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 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 or removal of seats) must be performed by a qual-
ified workshop.Note
If necessary, you can deactivate the front passenger's airbag by
means of the key-operated switch* ⇒page 208 .
