Seat belts
196The physical principles involved in a frontal collision are relatively
simple:
Both the moving vehicle and the passengers possess energy, which
is known as “kinetic energy” ⇒ page 195, fig. 204. The amount of
“kinetic energy” depends 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 energy 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
energy increases by a factor of four. Because these passengers are
not restrained by seat belts, the entire amount of kinetic energy has
to be absorbed at the point of impact ⇒fig. 205. 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. A rule of
thumb: 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 injuries 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, wind-
screen, etc ⇒ fig. 206. Passengers not wearing their belts risk being
thrown out of the car, resulting 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.

Airbag system
206Important 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 th e vehicle is in motion, you are at greater
risk of injury should the side airbags on the front seats or the outer
rear seats* be triggered in an accident. This applies particularly to
children if they are not properly protected by a child restraint
system ⇒page 212, “Important notes on side airbags and child
safety”.
•
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 210, “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 (front and rear*).
•
The sensors for the airbags are lo cated 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 dama ge 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.
•
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heavy 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 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 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 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) must always be performed by a qualified
workshop. Otherwise the airbag system may fail to work
properly.WARNING (continued)

208second). 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 head-protection airbags
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 to ensure that the area around the openings for
the head-protection airbags remains unobstructed at all times, so
that the airbags can in flate properly if needed.
•
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heavy or sharp-edged objects in the
pockets. When using the coat hooks, do not hang the clothes on
coat hangers.
•
The space between the passenge rs and the head-protection
airbags must never be occupied by children, other passengers or
pets. Passengers should never lean out or put a hand or arm out of
the window while the vehicle is in motion.
•
Do not move the sun visors out to cover the side windows if
there is anything attached to th em (such as pens or a remote
control for the garage door). These objects could cause injury if the
head-protection airbag is triggered.
•
The sensors for the airbags are lo cated 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 dama ge 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.
•
Where sun blinds are fitted on th e rear doors, these must not
obstruct or impair th e 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 trigge red. When the head-protection
airbag opens, parts of these acce ssories could be thrown into the
vehicle and injure passengers ⇒page 277 .
•
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), mu st 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.

Child safety
210Child safetyPoints to remember if children are
travelling in the carIntroduction
Statistics show that children are generally safer on the
rear seat than on the front passenger's seat.Children under 12 years of age shou ld normally travel on the rear
seat
2). Children travelling on the rear seat must use a child restraint
system or the seat belts provided, depending on their age, height
and weight. For safety reasons, the child restraint system should be
installed behind the front passenger's seat.
The physical principles involved and the forces acting in a collision
apply to children just as much as adults ⇒ page 195, “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 213,
“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 dealers. The
“Huckepack” range includes suitable restraint systems for all ages. These systems have been specially developed and tested for use in
Audi vehicles and comply with the ECE-R 44 standard.
Follow the manufacturer's instru
ctions 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 vehicl e is in motion.
•
Children who are less than 1.5 metres tall must not wear a
normal seat belt without a child rest raint, as this could cause inju-
ries to the abdominal and neck areas.
•
Babies and children must neve r travel on another occupant's
lap.
•
A suitable child safety seat can protect your child ⇒page 213,
“Child safety seats”.
•
Never allow two children to o ccupy 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 ac cident, the child coul d be catapulted through
the car, causing possibly fatal injuries to itself and other occu-
pants.
2)Observe any restrictions or regulations to the contrary.

Child safety
212Applies to vehicles: with side airbagsImportant notes on side airbags and child safety
Children must never sit too close to the opening for the
side airbag.The side airbags offer increased protection in a side-on collision.
In order to be effective, the side airbags need to inflate very quickly
(within fractions of a second) ⇒page 205, “How the side airbags
work”.
The airbag inflates with such force that injury can be caused if the
occupant is not sitting upright, or if there are any objects close to
the opening for the side airbag. This applies particularly to children if they are travelling in a way
which does not comply with the statutory safety regulations.
Incorrect position – danger
of injury from the side
airbag
If the side airbag were to inflate in an accident, it would strike the
child on the head and most likely cause serious injury ⇒fig. 224.
Correct position – properly restrained in a suitable
child safety seat
The child is correctly seated in a suitable child restraint system on
the rear seat ⇒ fig. 225. There is enough space between the child
and the opening for the side airbag.
In an accident, the airbag would be able to inflate completely to
offer maximum protection.
WARNING
To help prevent serious injury, children travelling in the vehicle
must always be protected with a restraint system which is suited
to their age, he ight and weight.•
The child's head must always be well away from the opening
for the side airbag. There is a risk of suffering injury.
•
Do not leave or place any object s in the space next to the side
airbag. There is a risk of suffering injury.Note
If required, you can have the side airbags for the rear passengers
deactivated by a qualified workshop.

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).
Child safety seat: category 0 / 0+
A suitable child safety seat and a correctly worn seat belt
can protect your child.Babies up to about 9 months old / 10 kg and infants up to about
18 months old / 13 kg are best protected by child safety seats that
can be adjusted to a horizontal position ⇒fig. 226.
Follow the manufacturer's instru ctions and observe any statutory
requirements when installing and using child restraints
⇒ page 210, “Important safety notes for using child safety seats”.
WARNING
Never install a rearward-facing child safety seat on the front
passenger's seat if the front pass enger's airbag has not been deac-
tivated ⇒page 211 . This can result in serious or possibly fatal
injury.

Child safety
218Possible alternatives for securing a child safety seat
A child safety seat can be secured on the rear seats and
on the front passenger's seat.The following alternatives are available for safely securing a child
safety seat on the rear seats and on the front passenger's seat.•
Child safety seats of the categories 0 to 3 can be secured with the
standard three-point seat belts.
•
Child safety seats of the categories 0, 0+ and 1 with the “ISOFIX”
system can be secured without seat belts using the “ ISOFIX”
retainers* ⇒page 218 .
Compatibility of vehicle seat positions for child safety seats
(according to EC directive 77/541):
“universally compatible”
The front passenger's backrest must be set as far forward as
possible or adapted to the child safety seat as required, and the
seat height must be adjusted to its highest position.
The front passenger's airbag must be deactivated if a rearward-
facing child seat is used.
The front passenger's seat ca n be equipped with optional
“ ISOFIX ” retainers.
The rear seats can be equipped with optional “ ISOFIX” retainers.
WARNING
While the vehicle is moving, chil dren must always be protected
with a restraint system which is suited to their age, height and
weight. Please refer to the chapter “Child seat categories”.•
Never install a rearward-facing ch ild safety seat on the front
passenger's seat unless the fr ont passenger's airbag has been
deactivated. This could result in potentially fatal injuries. If you
have no alternative but to let a ch ild travel on the front passenger's
seat, the front passenger's airbag must be deactivated before-
hand. Please refer to the chapter “Deactivating airbags”.
•
Note the important information and warnings concerning the
use of child safety seats found in the chapter “Important safety
notes when using child safety seats” and in the installation
instructions provided by the manufacturer of the child safety
seat.
Applies to vehicles: with ISOFIX system“ISOFIX” child seat mounting system
Child safety seats with the “ISOFIX” system can be
secured quickly and easily.When removing or fitting the child safety seat, please be
sure to follow the manufacturer's instructions.

Your vehicle and the environment
230Anticipate well in advance
A car uses most fuel when accelerating. If you anticipate hazards
and speed changes well in advance, you will need to brake less and
thus accelerate less. Wherever possible, let the car slow down grad-
ually with a gear engaged , for instance when you can see that the
next traffic lights are red. This takes advantage of the engine
braking effect, reducing wear on the brakes and tyres. Emissions
and fuel consumption will drop to zero due to the overrun fuel cut-
off.
Change gear early to save fuel
An effective way of saving fuel is to change up quickly through the
gears. Running the engine at high rpm in the lower gears uses an
unnecessary amount of fuel.
Manual gearbox: Shift up to second gear as soon as possible. If
possible, we recommend shifting up to the next gear at approx.
2,000 rpm.
Automatic gearbox: Press the accelerator slowly and avoid using
the “kick-down” feature.
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption, exhaust emissions
and noise levels all increase very ra pidly at higher speeds. Driving at
moderate speeds will help to save fuel.
Do not let the engine idle for longer than necessary
It is worthwhile switching off the engine when waiting in a traffic
jam, at level crossings or at traffic lights with a long red phase. The
fuel saved after only 30 - 40 seconds is greater than the amount of
fuel needed to restart the engine.
The engine takes a very long time to warm up when it is running at
idling speed. Mechanical wear and pollutant emissions are also
especially high during this initial warm-up phase. It is therefore best
to drive off immediately after starting the engine. Avoid running the
engine at high speed. Regular servicing
Regular servicing can establish a basis for good fuel economy
before you start driving. A well-serviced engine gives you the
benefit of
improved fuel efficiency as well as maximum reliability
and an enhanced resale value. A badly tuned engine can consume
up to ten percent more fuel than necessary.
Avoid short trips
The engine and emission control system need to reach their proper
working temperature in order to minimise fuel consumption and
emissions.
A cold engine uses disproportionately more fuel. The engine only
reaches its working temperature after about four kilometres, when
fuel consumption will return to a normal level. This is the reason
why we recommend avoiding short trips wherever possible.
Maintain the correct tyre pressures
Always make sure the tyres are in flated to the correct pressures
⇒ page 268 to save fuel. If the tyre pressures are just 0.5 bar too low,
this can increase the fuel consumption by as much as 5 %. Due to
the greater rolling resistance, under-inflation also increases tyre
wear and impairs handling.
Do not use winter tyres all through the year; they will increase fuel
consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel consumption, so it is
worth checking the luggage comp artment occasionally to make
sure that no unnecessary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even
when it is no longer needed. At a speed of 100-120 km/h your car will
use about 12 % more fuel as a result of the extra wind resistance
caused by the roof carrier - even when it is empty.
