& WARNING (conti nued)
• Never recline the front passenger's seat to transport objects.
Items can also move into the area of the s ide airbag or the front
airbag during braking or in a sudden maneu ver. Objects near the
airbags can become projectiles and cause injury, particularly when
the seat is reclined .
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other br eathing
conditions.
• To reduce the risk of breathing problems, those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the veh icle or opening windows or doors.
• If you are in a colli sion in which airbags deploy, wa sh your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
scratches.
• If the residue should get into your eyes, flush them with
water .•

Important safety instructions on
monitoring the Advanced Airbag System
& WARNING
An airbag system that is not functioning properly cannot provide supplemental protection in a frontal crash.
• If the airbag indicator light comes on, it means that there may
be something wrong with the Advanced Airbag System.
It is
possible that the airbag will inflate when it is not supposed to, or
will not inflate when it should.
• Have the airbag system inspected immediately by your autho­
r ized Audi dealer.
& WARNING
If the front airbag inflates, a child without a child restraint, or in
a rearward-facing child safety seat, or in a forward-facing child
restraint that has not been properly installed will be seriously
injured and can be killed.
• Even though your vehicle is equipped with an Advanced Airbag
System, make certain that all children, especially 12 years and
younger, always r ide on the back seat properly restrained for their
age and size.
• Always install forward or rear-facing child safety seat s on the
rear seat -even with an Advanced Airbag System.
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on, immediately install the rear-facing child safety seat in a rear

seating position and have the airbag system inspected by your
authorized Audi dealer.
• A tight tether o r other strap on a rearward -facing child
restraint attached to the front pa ssenger seat can put too much
pressure on the weight -sensing mat in the seat and register more
weight than i s actually on the seat . The heavier weight regi stered
can make the system work as though an adult were on the seat
and deploy the Advan ced Airbag when it mu st be suppre ssed
causing serious or even fatal injury to the child .
• If , in exceptional circumstanc es, you must install a forward­
facing child restraint on the front passenger seat, always move
the seat into its rearmost po sition in the seat' s fore and aft adjust­
ment range, as far away from the airbag as possible . The backrest
must be adjusted to an upright position. Make sure that the PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on.
& WARNING
• If the PASSENGER AIR BAG OFF light doe s not go out when an
adult is sitting on the front passenger seat after taking the steps
described above, make sure the adult is properly seated and
restrained at one of the rear seating positions.
• Have the airbag system inspected by your authorized Audi
dealer before transporting anyone on the front passenger seat .
[ i ] Tips
If the we ight-sensing mat in the front passenger seat detects an
em pty seat , the front airbag on the passenge r side will be t urne d off,
and the PASSENGER AIR BAG OFF light will stay on .•

Repair, care and disposal of the airbags
Parts of the airbag system are
insta lled at many different places on
your Audi . Ins tall ing, remov ing, serv icing o r rep airi ng a pa rt in an
area of the vehicle ca n damage a part of a n airbag system and prevent
t ha t sys tem from working prope rly in a coll is io n.
Th ere are some importa nt things you have to know to ma ke sure t hat
the effectiveness of the system will not be impai red and that
dis ca rded compo nents do not cause injury or po llute t he e nvir on­
ment .
& WARNING
Improper care , serv icing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover, obstruct, or change the steering wheel horn pad or
airbag cover or the instrument panel or modify them in any way .
• Never attach any objects such as cup holders or telephone
mountings to the surfaces covering the airbag units.
• For cleaning the horn pad or instrument panel, use only a soft ,
dry cloth or one moistened with plain water . Solvent s or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly.
• Never repair, adjust, or change any part s of the airbag system .
• All work on the steering wheel, instrument panel , front seats
or electrical sy stem (including the installation of audio equip­
ment, cellular telephones and CB radios, etc. ) must be performed
by a qualified technician who has the training and special equip­ ment necessary .
• For any work on the airbag system, we strongly recommend
that you see your authorized Audi dealer or qualified workshop.
• Never modify the front bumper or parts of the vehicle body . ..,_
Vehicle care Do-it-yourself service Technical data

-Airbag system -
--=---=----------------
Vehicle damage, repair costs or even the lack of veh icle damage are
not necessarily an indication of over-sensitive or failed airbag activa­
tion . In some collisions, both front and side airbags may inflate.
Remember too, that airbags will deploy only once and only in certain
kinds of collisions -your safety belts are always there to offer protec­
tion in those accidents in which airbags are not supposed to deploy or
when they have already deployed.
The side airbag system will not deploy:
• when the ignition is turned off
• in side collisions when the acceleration measured by the sensor is
too low
• in front-end collision s
• in rear-end collisions
• in rollovers .
In some types of accidents the front airbags, side curtain airbags and
side airbags may be triggered together.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position=>
page 163.
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to activate the
airbag. •
How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants who are properly
restrained .
Fig. 141 Inflated side
airbags on left side
of
vehicle, rear side
airbag optional equip­
ment
When the system is triggered, the airbag is filled with propellant gas
and breaks through a seam in the seat surface area marked
"AIRBAG". It expands between the side trim panel and the passenger.
In order to help provide this additional protection, the side airbag
must inflate within a fraction of a second at very high speed and with
great for ce. The supplemental side airbag could injure you if your
seating position is not proper or upr ight or if items are located in the
area where the supplemental s ide a irbag expands. This applies espe ­
cially to children=>
page 167, "Child Safety". Supplemental s ide
airbags inflate between the occupant and the door panel on the side
of the vehicle that is struck in certain side collision=> fig. 141.
Although they are not a soft pillow, they can "cushion" the impact
and in th is way they can help to reduce the risk of injury to the upper
part of the body.
A fine dust may develop when the airbag dep loys. This is normal and
does not mean there is a fire in the vehicle. •

• The airbag indicator light in the instrument panel
The airbag system is monitored electronically to make certain it is
functioning properly at all times. Each time you turn on the ignition,
the airbag system indicator light will come on for a few seconds (self
diagnostics).
The side curtain airbag is not activated:
• if the ignition is turned off,
• in side collisions when the acceleration measured by the sensor is
too low,
• in rear-end collisions,
• in rollovers.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position =>
page 73,
"General recommendations" .
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your authorized
Audi dealer. The side curtain airbag may not work properly even
when the vehicle acceleration in a side collision is high enough to
activate the airbag. •
Safety first Vehicle OP-eration
Airbag system
How side curtain airbags work
Side curtain airbags can work together with side airbags
to help reduce the risk of head and upper torso injuries for
occupants who are properly restrained.
Fig. 143 Illustration
of principle: Inflated
s ide curtain airbags on
the left side
The side curtain airbags inflate between the occupant and the
w indo ws on the side of the vehicle that is struck in a side collision
=> fig . 143.
When the system is triggered, the side curtain airbag is filled with
propellant gas and breaks through a seam above the front and rear
side windows identif ied by the AIRBAG label. In order to help provide
this additional protection, the side curtain airbag must inflate with in
the blink of an eye at very high speed and with great force. The side
curtain airbag could injure you if your seating position is not proper or
upright or if items are located in the area where the supplemental
side curtain airbag inflates. This applies especially to ch ildren
::::>page 167.
Although they are not a soft pillow, side curtain airbags can "cushion"
the impact and in this way they can help to reduce the risk of injury to
the head and the upper part of the body.
A fine dust may develop when the airbag deploys. This is quite no rmal
and does not mean there is a fire in the vehicle. •

Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Airbag System" in compli­
ance wi th Uni ted St ates Federa l Mo to r Vehicle Safety St andar d
(FMVSS) 208 as applicable at the time your veh icle was manufac­
tu red . The Advanced A
irbag system in yo ur vehicle has been certif ied to
mee t the "low -r is k" requiremen ts fo r 3-and 6-ye ar old ch ildre n on
t he passenger side and small adults on the dr iver side . The low risk
dep loyment criteria are inten ded to reduce the risk of injury through
interaction with the a irbag t hat can occur, for example, by being too
close to the stee ring wheel an d instr ument panel when the airbag
inflates. In addi tion, the sy stem has been certified to comp ly with t he
"suppression" requirements of the Safety Standa rd, to t urn off the
fron t air bag for infan ts u p to 1 2 months who a re res tra ined on the
front passenger seat in child restrai nts that are listed in the Stan­
d ar d.
Even thoug h your vehicle is equipped with an Advanced Airbag
system , a ll ch ildren, especially those 12 years and yo unger, should
always r ide in t he back seat p roperly restrained for t heir ag e and si ze .
Th e ai rbag on the passenge r si de makes the front seat a potentia lly
dange rous p lace for a child to r ide. Th e front seat is not th e safest
place fo r a child in a forward- facing c hild safety seat. It can be a very
d an ge rous p lace for a n infan t or a large r chil d i n a rea rwa rd-facing
seat. •

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of everybody
in the vehicle, especially children:
Always use the right child safety seat for each child and
always use it properly~
page 172.
-Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking retractor on the safety belt to prevent the child safety seat
from moving ~
page 177.
-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety seat
to the front passenger seat, make sure that it is not so
tight that it causes the weight-sensing mat to measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size . _,,
