Safety. Supplemental side airbags inflate be­
tween the occupant and the door pane l on the
side of the vehicle that is struck in certain s ide
collis ion¢
fig. 158 .
Although they a re not a soft pillow, they can
"cushion" the impact and in this way they can he lp to reduce the r isk of injury to the upper
part of the body.
A fine dust may develop when the airbag de­ p loys. This is norma l and does not mean there
is a fire in the veh icle .
Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al­
ways properly wear safety belts and ride in a
proper seating position .
There is a lot that you and your passengers
must know and act accordingly to help the
safety belts and a irbags do the ir job to pro­
vide supplemental protection .
A WARNING
An inflating side airbag can cause ser ious
or fatal injury. Improperly wearing safety
belts and improper seating positions in­
crease the risk of ser ious personal inju ry
and death whenever a vehicle is being
used.
- In orde r to reduce the risk of injury when
the supplemental side airbag inflates :
- Always sit in an upright pos ition and
never lean against the area where the
supp lemental s ide a irbag is located.
- Never let a chi ld or anyone else rest
their head against the side trim panel
in the area where the supp lemental
side ai rbag inflates.
- Always make sure that safety belts are
wo rn correctly,
- Do not let anyone sitting in the front
seat put their hand or any other parts
of their body out of the window.
- Always make sure that the side airbag
can inflate witho ut interference.

-Never install seat covers or rep lace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat c ushions that
cover the areas where the side a irbags
deploy.
- Damage to the orig inal seat cove rs or
to the seam in the area of the side a ir­
bag module must always be repaired
i mmediately by an author ized Audi
dealer.
- Objects between you and the airbag ca n
increase the risk of injury in an accident
by inter fer ing with the way the airbag
unfo lds o r by being pushe d in to yo u as
the airbag inflates .
- Never place or attach accessor ies or
othe r objects (such as cupho lders, tele­
phone brackets, or even large, bu lky
objects) on the doo rs, over or near the
area marked "A IRBAG" on the seat
bac krests.
-Such objects a nd accessories can be­
come dangerous project iles and cau se
i njury when the s upplementa l side air­
bag deploys .
- Never carry any ob je cts o r pe ts in the
deployment space be twee n them and
the airbags or allow ch ild ren or other
passengers to trave l in t his position.
- Always use the b uilt-in coat hooks on ly

- The electronic control mod ule and externa l
side impact sensors
- The side curtain airbags above the front and
rear side windows
- T he airbag ind icator light in the ins trument

The airbag system is monitored elect ron ica lly
to make certa in it is f unct ion ing properly at a ll
times. Eac h time you t urn on the ign ition, the
ai rbag system indicator light will come on for
a few seconds (se lf diagnostics) .
The side curtain airbag is not activated:
-if the igni tion is turned off,
- in s ide collisions when the accelerat ion
measured by the sensor is too low,
- in rear -end collisions,
- in ro llovers.
_&. WARNING
- Safety belts and the a irbag system will

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. 1 60 Illus trati on of pr in cip le: Inflat ed s ide curtain
airbags o n the left side
The side curtain airbags inflate between the
occupant and the windows on the s ide of the
vehicle that is struck in a side coll is ion
~ fig . 160.
When the system is trigge red, the side curta in
airbag is filled with prope llant gas and breaks
t hr ough a seam above the front and rear side
windows iden tified by the AIRBAG labe l. In or­
der to he lp prov ide this additional protection,
the side curtain ai rbag m ust inflate within the
blink of an eye at very high speed and with
great force. The side curtain a irbag co uld in­
jure you if your seating position is not proper
or upright or if items are located in the area
where the supplemental side curta in a irbag
inflates . This applies especially to ch ild ren
~ page 167.
Although they are not a soft pillow, side cur­
tain a irbags can "cushion " the impact and i n
th is way they can help to reduce the risk of in­
jury to the head and the uppe r part of the
body .
A f ine dust may deve lop when the airbag de­
ploys . T his is quite normal and does not mean
there is a fire in the vehicle.

166 Airbag sys te m
Important safety instructions on the
side curtain airbag system
Airbags are only supplemental restraints. Al­
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
a irbags do the ir job to prov ide s upplement al
protection.
_&. WARNING
-
Improperly wearing safety belts and im­
proper seating positions increase the risk
of serious personal injury and death when­
ever a veh icle is being used.
- Never let occ upants p lace any parts of
their bodies in the area from wh ich the
side curtain airbags inflate.
- Always make sure that the side curtain
airbags can inflate w ithout interference.
Unsuitable accessories fitted inside the
expansion range of a head a irbag can
dangerously interfere w ith its function . A
deploying head a irbag develops enough
force to catapult any piece of add-on
component out of its pa th of inflation
and into the passenger compartment. An
occupant hit by such a projectile can suf­
fer serio us injury or death

Technical Modifications.
- Do not swivel the sun visors to the side if
yo u have any objects clipped onto them
(for example pens).
If the a irbag should
deploy, you could be injured by these ob­
jects.
- Use the built-in coat hooks only for light­
weight cloth ing. Never leave any heavy or
sharp-edged objects in the pockets that
may interfere with airbag deployment
and can cause pe rsonal injury in an acci­
dent.
- Never use hange rs to hang clothing from
the hooks.
- Only use factory-installed sun shades or,
in the case of shades installed after the
vehicle leaves the fac to ry, only Audi roll­
up sunsc reens m ay be used~
page 277,
Additional accessories and parts re­
placement.
-Always sit in p roper seating position and
wear safety belts wh ile traveling so that
the side curtain airbags can help prov ide
protection.
- The airbag system can only be triggered
once. If the airbag has been triggered,
the system must be replaced by an au­
thor ized Audi dealer or qualified work­
shop.
-Always have work involving the side cur­ tain airbag system, removal and installa­
tion of the airbag components, or other repairs performed by an authorized Audi
deale r o r qualified workshop. O therwise
the air bag system may not work co rrec t­
ly.
- Never attempt to mod ify any compo­
nents o f the ai rbag system in any way.

168 Child Safety
-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 does
not come on and stay on, immediately
install the rearward-facing child safety
seat in a rear seating position and have
the airbag system inspected immediately
by your authorized Audi dealer.
.&, WARNING
If, in exceptional circumstances, you must
install 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 passenger front and side airbag.
- Always follow the manufacturer's in­
structions provided 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 installing
the child restraint. The backrest must be adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with
United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured . The
Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas ­
senger side makes the front seat a potentially
dangerous place for a child to ride . The front
seat is not the safest place for a child in a for­
ward-facing child safety seat.
It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat.
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight-sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight-sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its "footprint" vary for different kinds of child re -
straints and for the different models of the .,.

Child safety seats
Infant seats
Babies and infants up to about one year old
and 20 lbs. or 9 kg need special rearward -fac ­
ing child restraints that support the back,
neck and head in a crash.

.,. Secure unused safety belts on the rear seat
¢page 172.
Infants up to about one year (20 lbs . or 9 kg)
are best protected in special infan t carriers
and child safety seats designed for their age
group . Many experts believe that infants and
small children should ride only in spec ial re­
straints in which the ch ild faces the back of
the vehicle. These infant seats support the ba­
by's back, neck and head in a crash
¢ fig . 162.
The airbag on the passenger side makes the
front seat a po tentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forward -facing child seat.
It is a very dangerous p lace for an infant or a
l arger ch ild in a rearward-facing seat.

A toddler or child is usually too large for an in­
fant restraint if it is more than one year old
and weighs more than 20 lbs. (9 kg) . Toddlers
and children who are older than one
year up to about 4 years old and weigh more
than 20 lbs. (9 kg) up to 40 lbs. (18 kg) must
always be properly restrained in a child safety
seat certified for their size and weight
c::> fig . 163 and c::> fig . 164 .
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 child in a forward-facing child safe­
ty seat . It is a very dangerous place for an in­
fant or a larger child in a rearward-facing seat.
_&. WARNING
Not using a child safety seat, using the
wrong child safety seat or improperly in­
stalling a child restraint increases the risk
of serious personal injury and death in a
collision or other emergency situation.
- Children on the front seat of any car,
-
even with Advanced Airbags, can be seri­
ously injured or even killed when an air­ bag inflates . A child in a rearward-facing
child safety seat installed on the front passenger seat will be seriously injured
and can be killed if the front airbag in­
flates -even with an Advanced Airbag
System .
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always install rearward-facing child safe­
ty seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rearward-facing
child safety seat in a rear seating posi­
tion and have the airbag system inspect­
ed by your authorized Audi dealer .
- The rear side of the child safety seat
should be positioned as close as possible ..,.
