The head-protection airbag system is triggered in
certain types of side collision
^>Fig.
235. Further
airbag systems may also be triggered, depending
on the circumstances.
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. 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 re­
straining uncontrolled movement of the head,
the airbag also reduces the forces acting on the
neck.
In order to provide the desired extra protection in
an accident, the airbags have to inflate extremely
rapidly (within fractions of
a
second).
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 ac­
cident.
A WARNING
- It is important to ensure that the area
around the openings for the head-protec­
tion airbags remains unobstructed at all

times,
so that the airbags can infLate prop­
erly 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 passengers and the
head-protection airbags must never be oc­
cupied 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 them (such as pens or
a
garage door
opener). These objects could cause injury if
the head-protection airbag is triggered.
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 function of the side air-

bags.
Any damage to the front doors could
Lead to faults in the system. Repairs or any
other work on the front doors must there­
fore always be carried out by
a
qualified
workshop.
Sun blinds fitted on the rear doors 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 im­
paired if the system is triggered. When the
head-protection airbag opens, parts of
these accessories could be thrown into the
vehicle and injure passengers
^>page
340.
Any work involving the head-protection air-

bags,
or removal and installation of the air-
bag components for other repairs (such as
repairs to the roof liner), must always be
performed by
a
qualified workshop. Other­
wise the airbag system may fail to work
properly.

If
you
have no alternative but to install
a
rear­

ward-facing child seat on the front passenger's
seat you must deactivate the front passenger's
airbag beforehand.
We recommend that child seats should be fitted
on the rear seat so that the front passenger's air-
bag can remain functional and provide protection
in an accident

a few seconds every time the ignition is switched

on.

If the front passenger's airbag has been deactiva­

will light up
constantly as a reminder

A WARNING

- If
you
have no alternative but to install a
rearward-facing child seat on the front pas­
senger's seat, the front passenger's airbag
must be deactivated beforehand. Potential­
ly fatal injuries to the child can result if the
front passenger's airbag is not deactivated

•=>
page 267
- If
you
have deactivated the front passeng­
er's airbag, reactivate it as soon as the child
seat is no longer needed so that the airbag
can continue to give the required protec­

tion.

- It is the driver's responsibility to ensure that
the key-operated switch is set to the correct

position.

Accessories
and

to the
vehicle
Accessories,
replacement parts
and

repairs
Always
ask
your dealer
or
specialist retailer
for

advice before purchasing accessories
and
re­
placement parts.
Your
car is
designed
to
offer
a
high standard
of

active and passive safety. For this reason,
we
rec­
ommend that you ask your Audi dealer
for
advice
before fitting accessories
or
replacement parts.
Audi dealers have
the
latest information from
the manufacturer and
can
recommend accesso­
ries and replacement parts which
are
suitable
for

your requirements. They can also answer
any

questions you might have regarding official
regu­

lations.
We recommend you
to
use only Audi accessories
and Audi Genuine Parts. Audi has tested these
products
for
suitability, reliability and safety.
Audi dealers have
the
necessary experience
and

facilities
to
ensure that
the
parts
are
installed
properly.
Although
the
market
is
constantly scrutinised,
Audi
cannot
judge
or
assume responsibility
for

the reliability, safety and suitability
of
non-genu­
ine products
-
even though
in
some instances,
these parts
may
have been approved
by
an
offi­

cially recognised technical testing authority
or

accompanied
by
an official approval certificate.
Any retro-fitted equipment which has a direct
ef­

fect on
the
vehicle and/or
the
way
it is
driven

(e.g.
cruise control system
or
electronically-con­
trolled suspension) must
be
approved
for
use
in

your vehicle and bear
the e
mark
(the
European
Union's approval symbol).
If any additional electrical components are fit­
ted which
do not
serve
to
controL
the
vehicLe
it­

self
(for
instance a refrigerator box, laptop
or

ventilator
fan,
etc.), these must bear the C€ mark
(manufacturer conformity declaration
in the Eu­

ropean Union).

A,
WARNING

Never attach accessories (such
as cup
holders
or telephone brackets)
to the
surfaces cover­
ing
the
airbag units
or the
areas around
the

airbags: this could cause injury
if
the airbag
is

triggered.

Modifications
Modifications must always
be
carried
out
accord­
ing
to our
specifications.
Unauthorised modifications
to the
electronic
components, software, wiring
or
data transfer
in

the vehicLe may cause malfunctioning. Due
to the

way
the
electronic components
are
linked togeth­
er
in
networks, other systems
may be
affected
by

the faults. This can seriously impair safety, lead
to excessive wear
of
components,
and
also inva­
lidate
the
type approval
for
your vehicle.
You will appreciate that your Audi dealer cannot
be held liable
for
any damage caused
by
modifi­
cations and/or work performed incorrectly.
We recommend that
all
work should
be
per­
formed
by
an Audi workshop using Audi Genuine

Parts.

/K
WARNING

- Incorrectly performed modifications
or
oth­

er work
on
your vehicLe can lead
to
malfunc­
tions and cause accidents.
-
Do not
use an additional
or
replacement
number plate holder other than
the
original
one fitted
at the
front
of
the vehicle.
Radio transmitters
and

business equipment
Transmitters
An external aerial
is
required
in
order
to
operate
radio equipment inside
the
vehicle. The maxi­
mum range
of
the equipment can only
be
ach­

ieved with
an
external aerial.
Retrofit installations
of
radio transmitters
in the

vehicle
are
subject
to
official approval and can
af­

fect
the
type approval
for
your vehicle.

extreme cases this could mean
that
you lose the
type approval
for
your vehicle.
Qualified workshops will be able to inform you
about options for installing and operating radio
transmitters.
Business equipment
Retrofit installation of business or other equip­
ment in the vehicle is permitted, provided the
equipment cannot interfere with the driver's im­
mediate controL of the vehicle. Any such equip­
ment must carry the
CC
mark. Any retrofit equip­
ment that could influence the driver's control of
the vehicLe must have a type approval for road
vehicles and must carry the e mark.
A WARNING
- Loose or incorrectly secured radio equip­
ment could be catapulted through the
vehi­

cle during sudden driving/braking manoeu­
vres or in the event of an accident. This
poses a risk of injury to occupants.
- Always ensure that radio equipment is prop­
erly secured outside the deployment area of
the airbags or stowed safely while the
vehi­

cle is moving.
- Mobile telephones or radio equipment
which are operated inside the vehicle
with­

out
a
correctly installed external aerial can
create excessive magnetic fields that could
cause a health hazard.
© CAUTION
If
you
use radio equipment in the car without
an external aerial, the electromagnetic radia­
tion in the vehicle could exceed the recom­
mended limits. This also applies to external
aerials which have not been correctLy instal­

led.

- Do not operate radio equipment in the
vehi­

cle unless an external aerial is properly
con­

nected.

Please observe the relevant regulations and
follow the instructions in the operating
man­

ual for the radio equipment.
