2011 AUDI A3 light

• 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. •

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. •

Important safety instructions on the side
curtain airbag system
Airbags are only su pple mental restra ints . Alwa ys prop­
erl y we ar s afe ty belts and ride in a proper se ating posi ­
tion .
There i s a lot t hat you an d your pass eng ers m ust kno w and do to help
the saf ety be lts and airbags do t heir j ob to provide supp lemental
protec tion.
in. WARNING
Improperly wearing safety belts and improper seating positions
increase the risk of serious personal injury and death whenever a
vehicle is being used.
• Never let occupants place any parts of their bodies in the area
from which the side curtain airbags inflate.
• Always make sure that the side curtain airbags can inflate
without interference. Unsuitable accessories fitted inside the
expansion range of a curtain airbag can dangerously interfere with
its function. A deploying head airbag develops enough force to
catapult any piece of add-on component out of its path of inflation
and into the passenger compartment. An occupant hit by such a projectile can suffer serious injury or death :::::,
page 302, "Tech­
nical Modifications".
• Do not swivel the sun visors to the side if you have any objects
clipped onto them (for example pens). If the airbag should
deploy, you could be injured by these objects. • Use the built-in coat hooks only for lightweight clothing. Never
leave any heavy or sharp-edged objects in the pockets that may
interfere with airbag deployment and can cause per sonal injury in
an accident.
• Never use hangers to hang clothing from the hooks.
• Only use factory-installed sun shades or , in the case of shades
installed after the vehicle leave s the factory, only Audi roll-up
& WARNING (co ntinued )
sunscreens may be used:::::, page 301, "Additional accessories and
parts replacement ".
• Always sit in proper seating position and wear safety belts
while traveling so that the side curtain airbags can help provide
protection.
• The airbag system can only be triggered once . If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealer or qualified workshop.
• Always have work involving the side curtain airbag system,
removal and installation of the airbag components, or other
repairs performed by a qualified workshop. Otherwise the airbag
system may not work correctly.
• Never attempt to modify any components of the airbag system
in any way .•

& WA RNING (conti nued)
• Always install rear-facing child safet y seat s on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger seat in exceptional circumstances and the
PASSENGER AIR BAG OFF light do es not come on and stay on,
immediately in stall the rear-facing child safety seat in a rea r
seating position and have the airbag system inspected immedi­
ately by your authorized Audi dealer.
& WARNING
If , in exceptional circumstances , you must in stall a forward-facing
child restraint on the front passenger' s seat:
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for use on a front seat with a
pa ssenger front and side airbag.
• Always follow the manufacturer 's instructions p rovided with
the child safety seat or carrier.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible before install ing the child restra int . The back­
re st must be adju sted to an upright position .
• Always make sure that the PASSENGER AIR BAG OFF light
c omes on and stays on all the time whenever the ignition i s
switched on .•
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. •

Th e weigh t-sens ing ma t me asures tot al we ight of the child and the

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the
PASSENGER AIR
BAG OFF
light.
Controls and equip­ ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot­
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restra ints that must be used to cert ify compliance of
the Advanced Airbag System in yo ur vehicle with the suppression
requirements of Federal Motor Veh icle Safety Standard 208. These

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 . _,,

-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).
Infants up to about one year (20 lbs. or 9 kg) are best protected in
special infant carriers and chi ld safety seats designed for t heir age
group. Many experts believe that infants and small childr en should
r ide only in spec ia l restra ints in w hich the child faces the back of the
vehicle. These infant seats support the baby's back, neck and head in
a crash=> fig. 144.
The airbag on the passenger side makes the front seat a potentially
dangerous place for a child to ride. The front seat is not the safest
place for a ch ild in a forward-facing child seat.
It is a very dangerous
place for an infant or a large r child in a rear ward-fac ing seat.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a crash.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat· even with an Advanced Airbag System.
A child will be seriously injured and can be killed when the
inflating airbag hits the child safety seat or infant carrier with
great force and smashes the child safety seat and child against the
backrest, center armrest, door or roof=>
page 147, "Child
restraints on the front seat -some important things to know".
• Always install rear-facing child safety seats or infant carriers
on the rear seat.
• Never install a rear-facing child rest raint in the forward-facing
direction. Such restraints are designed for the special needs of
infants and very small children and cannot protect them properly
if the seat is forward-facing.
