Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 167 Side airbag locat ion in t he drive r's se at
The side airbags are located in the sides of the
front seat backrests
c:> fig. 167 facing the doors .
They are identified by the word "AIRBAG".
The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
c:> page 187,
Airbag system c:>page 194, Child safety
c:> page 216 .
The side airbag system basically consists of:
-the electronic control module and externa l side
impact sensors
212
-the two side airbags located in the sides of the
front backrests
-the airbag warning light in the instrument clus-
ter.
The airbag system is mon itored electron ically to
make certain that it is functioni ng properly at all
times. Each time you turn on the ignition, the air­
bag system indicator light will come on for a few
seconds (self diagnostics) .
The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col­
lision. The airbag deploys in side impacts and on­
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
unit, the side airbags will not be tr iggered, even
though the car may be badly damaged as a result
of the collision.
It is not possible to define an air­
bag triggering range that w ill cover every possi­
ble angle of impact, since the circumstances will
vary considerably between one collision and an­
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
c:> page 214, Important safety instructions on
the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in position in the event of a side collision
so that the side airbags can provide protection.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing your safety
belt and wear ing it properly. This is another rea­
son why you sho uld always wear your safety
belts, not just because the law requires you to do
so
c:> page 187, General notes.
It is impo rtant to remember that while the sup­
plemental side airbag system is designed to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bruising , friction
burns and minor abrasions can also be associated

with deployed side airbags. Remember too, side
airbags wi ll deploy on ly once and on ly in certain
kinds of acc idents -your safety be lts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
ve hicle damage are not necessarily an indication
of over-sensitive or failed airbag act ivation. In
some collisions, both front and side a irbags may
inflate. Remember too, that airbags will deploy
only once and only in ce rtain kinds of coll is ions
-
your safety belts are always there to offer protec­
tion in those acc idents in which airbags are not
supposed to deploy or when they have already
deployed.
The side airbag system will not deploy:
-when the ign ition is switched off
-in side collisions when the acceleration meas-
ured by the sensor is too low
-in front-end collisions
-in rear-end collisions
-in rollovers.
I n some types of accidents the front 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 214.
-If the airbag indicator light q page 14
comes when the vehicle is being used, have
the system inspected immed iate ly by your
authorized Audi dealer. It is possible that
the a irbag will inflate when it is not sup­
posed to, or will not inflate when it should.
Airbag system
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained.
Fig. 168 Inflated side airbag on left side of vehicle
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 ex­
pands between the side trim panel and the pas­
senger . In order to help provide this addit ional
protect ion, the side airbag must inflate w ith in a
fraction of a second at very high speed and with
great force. The supplemental sid e a irbag could
injure you if you r seating position is not proper or
u pr ight or if items are located in the area where
the supp lemental side airbag expands . This ap­
plies especially to children
¢ page 216, Child
safety.
Supplementa l side airbags inflate be ­
tween the occupant and the door panel on the
s ide of the vehicle that is struck in certain side
collision ¢
fig. 168.
Although they are not a soft pillow, they can
"cushion" the impact and in this 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 deploys.
This is normal and does not mean there is a fire
in the veh icle.

Airbag syste m
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
p roperly wear safety belts and ride in a proper
seating position.
There is a lot that you and your passengers must
know and act accord ingly to help t he safety be lts
and a irbags do the ir job to provide supplemental
protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury . Improperly wearing safety belts
and improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used .
- In order to reduce the risk of injury when
the supplemental s ide airbag inflates:
- Always sit in an up right posit ion and never
lean ag ainst the area where the s upple­
mental side airbag is located.
-
- Never let a chi ld or anyone else rest the ir
head agains t the side t rim p anel in the
area whe re the supp lemental s ide a irbag
inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the fron t seat
put their hand or any other parts o f the ir
body out of the window .
- Always make sure tha t the side airbag can
inflate without inter ference.
- Never install seat covers or rep lacement
upho lstery over the front seatbacks that
have not been specifically approved by
Aud i.
- Never use add itiona l seat cushions that
cover the areas where the s ide airbags de­
ploy .
- Damage to the origina l seat covers or to
the seam in the area of the side airbag
mod ule m ust always be repaired immed i­
ately by an authorized Audi dealer.
- Objects between you and the airbag can in­
cr ease t he risk of inju ry in an accident by in­
te rfe ring w ith the way the airb ag unfo lds or
214 by being pushed
into you as the airbag in­
flates .
- Never place or attach accessor ies or other
ob jects (s uch as cup ho lde rs, telephone
bracke ts, or even l arge, b ulk y objec ts) on
the doors, over or near the area mar ke d
"A IRBAG" on the seat backrests .
- Such objec ts and accessories can become
dange ro us projecti les and cause injury
when the supplemental side airbag de­ ploys.
- Never carry any objects or pets in the de ­
ployment space between them and the
airbags or allow children or other passen­
gers to trave l in this position .
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- The a irbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an authorized
Aud i dealership.
- Damage (cracks, deep scratches etc.) to the
or iginal seat covers or to the seam in the
area of the side airbag module must always
be repaired immediately by an authorized
Aud i dea le r.
- If ch ildren are seated imprope rly, thei r risk
of injury increases in the case of an accident
~ page 216, Child safety .
-Never attempt to mod ify any components of
the airbag system in any way.
- In a side collision, side airbags will not func­
tion properly if sensors cannot correctly measure increasing air press ure inside the
doors when a ir e scapes th rough large r, un­
closed openings in the door p anel.
- Never dr ive with interior door t rim panels
removed.
- Never dr ive when parts have been re­
moved from the inside door panel and the
openings they leave have not been proper­
ly closed .
- Never dr ive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly closed .

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
-Always make certain that openings are
covered or f illed if add itiona l speakers or
other equ ipment is installed in the inside
door panels.
- Always have work on the doors done by an
author ized Audi dealer or qualified work­
shop.

Important information
Introduction
The physical princip les of what happens when
your veh icle is in a cras h apply also to childr en
¢ page 188, What happens to occupants not
wearing safety belts?.
But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater risk of serious injury in crashes than
adu lts.
Because children's bodies are not fu lly devel­
oped, they require restraint systems especially
designed for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children .
In a frontal crash at a speed of 20-35 mph (30-56 km/h) the forces acting on a 13 lbs (6 kg)
infant will be more than 20 times the we ight of
the child . This means the weight of the child
wou ld suddenly be more than 260 lbs ( 120 k g).
Under th ese conditions, only an appropriate child
rest raint properly used can reduce the r isk of se­
rio us injury. Child restraints, like adult safety
be lts, must be used properly to be effective.
Used improperly, they can increase the risk of se­
rious inj ury in an accident.
If you must install a child restraint on the front
passenger seat in exceptional circumstances, be
sure to read and heed the important information
and warn ings
¢ page 195. Infants and other ch il­
dren who are properly restrained in an appropri­
ate child restraint that is for their size and age
can benefit from the protection that supplemen­
tal side airbags provide in some kinds of crashes .

instructions for using child safety seats.
Please
be sure to read and heed all of the important in­
format ion and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restraints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in your veh icle and how they work
when infants and children in ch ild restraints are
on the front passenger seat . Because of the large
amount of impo rtant informat ion, we ca nnot re­
peat it all he re. We urge you to read the detailed
inf ormation in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans ­
porting children on the front passenger seat.
Please be sure to heed the WARNINGS
-they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children .
.&_ WARNING
All vehicle occupants and especially child re n
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly re­
stra ined child could be injured by striking the
interior or by being ejected from the vehicle
during a sudden maneuver or impact . An un­
restrained or improperly restrained child is al­
so at greater r isk of injury or death through
contact w ith an inflating airbag.
A WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or
even killed when an airbag inflates. A ch ild in
a rearward-fac ing child safety seat installed
on the front passenger seat will be seriously
in ju red and can be killed if the front airbag in­
flates.
- The inflat ing airbag will hit the child safety
seat or infa nt carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, or
door.

dealer or author ized Audi Service Facility .
A WARNING
-Forward-fac ing ch ild seats insta lled on the
front passenge r seat may inte rfere with the
deployment of the a irbag and cause serious
persona l inju ry to the child .
- If except ional circumstances require the use
of a forward-facing child res traint on the
front passenger's seat, the child's safety
and well-being require the following special
precautions to be taken:
- Always make sure that the forward-facing seat has been designed and cert ified by its
manufacture r fo r u se on a front passenger
seat with a front and s ide a irb ag.
- Always carefully follow the manufacturer's
instr uctions provided with the child seat
or i nfan t ca rrier.
- Never p ut the fo rward-facing child re­
s tra int up against o r very near the instru­
men t panel.
- Always move the front passenger seat to
the highest posit ion in the up and down
ad justment range and move it back to the
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-fac ing ch ild restraint.
- Always make sure that the safety be lt up­
pe r anchorage is behind the child restra int
and not next to o r in front of the child re­
stra int so that the safety belt will be prop­
erly positioned.
- Always make sure that nothing prevents
the front passenger's seat from be ing
moved to the rearmost posit ion in its fore
and aft adjustment range .
- Never place objects on the seat (such as a
laptop, CD p laye r, electronic games de­
vice, powe r inverter or seat heater for
child se ats). These m ay influence the ele c-
Ch ild saf ety
trical capacitance measu red by the capac i­
tive passenger detection system and can also fly around in an acc ident and cause
serious personal injury .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, powe r inverter or seat heat ­
er for child seats) on the front passenger
seat if the device is connected to the 12-
vo lt socke t or the cigarette lighter so cket.
- If a seat heate r has been retrofitted or
othe rw ise added to t he front passenger
seat, neve r insta ll any child res traint sys­
tem on this seat.
- Make su re that there a re no wet objects
(s uch as a we t towe l) and no w ater or oth­
er liquids on the front passenger seat

Advanced front airbag system and children
Your veh icle is equipped w ith a front "Advanced
A irbag System" in comp liance w it h United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your veh icle has
been certified to meet the " low-risk" require ­
ments for 3- and 6-year old children on the pas­
senger 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 a irbag inflates. In addit ion, the
system has been certified to comply w ith the
" su ppress io n" req uirements of the Safety S tand­
ard, to tu rn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
E ven tho ugh yo ur vehicle is equipped with an
Ad a
vanced Airbag system, a chi ld should a lways ride
in the seat proper ly restrained for its age and
size. The airbag on the passenger side makes the
front seat a potentially dangerous p lace for a
child to r ide . The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dange rous place for a n infant or a
larger child in a rearward-fac ing seat.
The vehicle's Advanced Airbag System has a ca­
pac itive passenger detect ion system in the front
passenger seat cush ion that ca n detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on t his seat .
The capac it ive passenger detect ion system regis ­
ters the changes that result in an electr ical field
when a c hild, a child restra int, and a baby blanket
a re on the front passenge r seat. The change in
t he meas ured capacitance due to t he p resence o f
a child, a chi ld restraint, and a baby b lanket on
the front passenger seat is re lated to the chi ld
restraint system resting on the seat . The meas ­
ured capacitance of a ch ild restraint system var-
218
ies depending on the type of system and specific
make and mode l.
The elect rical capac ita nce of the va rious types,
makes, and models of child restra in ts speci fied
by the U.S . National Highway Tra ffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
c hi ld restraint is used on the front passenger
seat w it h a typical 1 year-old infant, t he Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detect ion
system wi th the data stored in the e lec tronic co n­
tro l unit .
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu ­
factu rer for use w ith an airbag . If in exceptional
c ir cumstances you m ust use it on the front pas­
senger seat, ca refully read all of the information
o n chi ld safety and Advanced Airbags and heed
a ll of th e app licab le WARNINGS . Make certain
that the chi ld and chi ld restraint are correctly
recognized by the capacitive passenger detection
system in the front passenger seat, that the front passenger a irbag is turned off, and that the air­
bag status is always correct ly signa led by the
PASSENGER AIR BAG OFF ~; light.
Many types and models of child restra ints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved designs and older models are taken out of
production . Ch ild rest rai nts are not standa rdized .
Child res tra ints of the same type typically have
d iffe rent weights and sizes and diffe re nt "foot ­
pr ints", the size and shape o f th e bo ttom of the
ch ild restraint that sits on the seat, w hen they
are installed on a vehicle seat . These differences
make it virtua lly impossib le to certify comp liance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been
sold in the past or will be sold over the course of
the useful life of your veh icle .
