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 loca ted above the doors on the left
and right sides of the vehicle ⇒page 207, fig. 220. The locations of
the airbags are marked with the word “AIRBAG”.
In conjunction with the three-point seat belts and side airbags, the
head-protection airbags give the occupants additional protection
against head and neck injuries in a severe side collision ⇒ in
“Important safety notes on the head-protection airbags” on
page 208 .
Together with other design features (including cross-braces in the
seats and the overall strength of the body structure), the sideguard
system offers an effective further improvement to occupant protec-
tion in side impacts.
How the head-protection airbags work
When fully inflated, the airbags reduce the risk of head or
chest injury in a side collision.In certain types of side collisions the head-protection airbag is trig-
gered together with the side airbag on the impact side of the vehicle
⇒ fig. 221.
When the system is triggered, the airbag fills with a propellant gas
and covers the entire area in front of the side windows, including
the door pillars. In this way the system is able to protect both the
front and the rear occupants on the side of the vehicle where the
impact occurs. The head-protection airbag inflates to soften the
impact if an occupant strikes parts of the interior or objects outside
the vehicle with their head. By reducing the head impact and
restraining uncontrolled movement of the head, the airbag also
reduces the forces acting on the neck. In addition, since it covers the
front door pillar when fully inflat ed, the head-protection airbag also
gives extra protection if the car shou ld collide with an obstacle at an
oblique angle.
The front airbags, side airbags and head-protection airbags may be
triggered together in certain types of accident.
In order to provide the desired extra protection in an accident, the
airbags have to inflate extremely rapidly (within fractions of a

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.

The key-operated switch for deactivating the front
passenger's airbag is located in the glove box ⇒fig. 222.
– To deactivate the front passenger's airbag, insert the ignition key into the switch and turn it to position .
– The front passenger's airbag can be reactivated by turning the key to position .Deactivating front passenger 's airbag when a child
safety seat is in use
If you have no alternative but to i nstall a rearward-facing child safety
seat on the front passenger's seat you must deactivate the front
passenger's airbag beforehand.
We recommend, however, that child seats should be only fitted on
the rear seat so that the front passenger's airbag can remain func-
tional and provide protection in an accident ⇒page 210 .
Monitoring of airbag system
The airbag warning lamp will light up for a few seconds every time
the ignition is switched on.
If the front passenger's airbag ha s been deactivated via the key-
operated switch, the indicator lamp “PASSENGER AIRBAG OFF” will
light up constantly as a reminder ⇒page 209, fig. 223. Please refer
also to the description of the
 warning lamp in the instrument
cluster ⇒page 17 . When the front passenger's airbag is deactivated using the key-
operated switch, the seat belt warning lamp for the front passenger

⇒ page 18 is also switched off.
WARNING
•
If you have no alternative but to install a rearward-facing child
seat on the front passenger's se at, the front passenger's airbag
must be deactivated beforehand. Po tentially fatal injuries to the
child can result if the front passenger's airbag is not deactivated!
⇒ page 211, “Using a child safety seat on the front passenger's
seat”
•
If you have deactivated the fron t passenger's airbag, reactivate
it as soon as the chil d 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.Note
All the other airbags in the car will remain functional if the front
passenger's airbag has been deactivated with the key-operated
switch.

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.

•
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 particularly the case if the child is travelling on the front
passenger's seat and the airbag system is triggered in an accident.
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 co rrect position ⇒page 197, “How to wear seat belts
properly”. Always check that th e belt is properly positioned
according to the instru ctions 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 if the front pass enger's airbag has not been deac-
tivated ⇒page 211 .
•
Extra caution is advised if you ar e 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 ti ghtened 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
workshop.
Using a child safety seat on the front passenger's seat
Whenever possible, child safety seats should always be
installed on the rear seat.For safety reasons, we recommend that child safety seats should be
installed on the rear seats whenever possible. However, if you have
to use a child seat on the front passenger's seat when there is no
other alternative , it is most important to note the following warn-
ings:
WARNING
•
Do not use a rearward-facing child safety seat on the front
passenger's seat unless the fr ont 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 alte rnative but to use a rearward-
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.
•
Make sure that the front passen ger'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 pass enger's seat must be moved back
to the rearmost position.

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.
