Advanced Airbag  System  components 
The front  passenger  seat  in your  vehicle  has  a  lot  of very  important  parts  of  the  Advanced 
Airbag  System  in  it.  These  parts  include  the 
weight-sens ing  mat,  sensors,  wiring,  brack
ets,  and  more . The  fu nction  of the  system  in 
the  front  passenger  seat  is checked  by the 
e lectronic  control  u nit  when  the  ignit ion  is on. 
The  control  unit  mo nitors  the  Advanced  Air
bag  Sys tem  and  turns  the  airbag  indicator 
light  on  when  a  ma lfunction  in the  system 
components  is  detected . The function  of  the 
ai rbag  ind icator  light  is described  in  greater 
detai l below.  Because  the  front  passenger 
seat  contains  important  parts  of the  Ad
vanced  A irbag  System,  you  must  take  care  to 
prevent  it  from  be ing  damaged . Damage  to 
the  seat  may  prevent  the  Advanced  A irbag  for 
the  front  passenger  seat  from  doing  its  job  in 
a  cra sh . 
The front  Advanced Airbag  System 
consists of the  following: 
- Crash  senso rs  in the  front  of the  veh icle  that 
measu re  ve hicle  ac celera tion/de ce le ra ti on 
to  provide  info rm ation  to  the  Advanced  Air
bag  System  abo ut  the  severity  of  the  crash . -
An elect ronic  contro l unit,  with  integrated 
crash  sensors  for  front  and  side  impacts . 
The  control  un it  "decides"  whether  to  fi re 
the  front  a irbags  based  on  the  informat ion 
received  from  the  crash  sensors.  The  contro l 
un it  also  "decides"  whether  the  safety  belt 
prete nsioners  shou ld  be  act ivated . 
- An Advanced  A irbag  w ith  gas  generator  for 
the  dr iver  inside  the  stee ring  wheel  hub . 
- An Advanced  A irbag  w ith  gas  generator  in
side  the  instrument  panel  for  the  front  pas
senge r. 
- A we ight-sensing  mat  under  the  up ho lstery 
padding  of the  front  passenger  seat  cushion 
that  measures  the  total  weight  on  the  seat . 
The  informat io n  registe red  is sent  continu
ou sly to  the  elec troni c con tro l unit  to  regu 
la te  deployment  of the  front  Advanced  Air

-Improper  repair  or  disassembly  of  the 
front  passenger  and  driver  seat  will  pre
vent  the  Advanced  Airbag  System  from 
functioning  properly . 
- Repairs  to  the  front  passenger  seat  must 
be  performed  by qualified  and  properly 
trained  workshop  personnel. 
- Never  remove  the  front  passenger  or 
dr iver  seat  from  the  veh icle . 
- Never  remove  the  upholstery  from  the 
front  passenger  seat . 
- Never  disassemble  or  remove  parts  from 
the  seat  or  disconnect  wires  from  it. 
- Never  carry  sharp  objects  in your  pockets 
or  place  them  on  the  seat.  If  the  weight
sensing  mat  in the  passenger  seat  is 
punctured  it  cannot  work  properly. 
- Never  carry  things  on your  lap  or  carry 
objects  on  the  passenger  seat . Such 
items  can  increase  the  weight  registered 
by the  weight-sens ing  mat  and  send  the 
wrong  info rmation  to  the  airbag  control 
unit. 
- Never  store  items  under  the  front  pas
senger  seat.  Parts  of the  Advanced  Ai r
bag  System  under  the  passenger  seat 
cou ld  be  damaged,  preventing  them  and 
the  airbag  system  from  working  proper 
ly . 
- Never  place  seat  covers  or  replacement 
upholstery  that  have  not  been  specifical
ly approved  by A udi on  the  front  seats. 
- Seat  covers  can  prevent  the  Advanced 
Airbag  System  from  recognizing  child  re
straints  or  occupants  on  the  front  pas
senger  seat  and  prevent  the  side  airbag  in the  seat  backrest  from  deploy ing  prop
erly. 
- Never  use  cush ions,  pillows,  blankets  or 
similar  items  on  the  front  passenger 
seat . The  add itional  padd ing  will  prevent 
the  weight-sens ing  mat  in the  seat  from 
accu rately  reg iste ring  the  ch ild  restra int 
or  person  on  the  seat  and  prevent  the 
Advanced  Airbag  System  from  function ing  properly . 
-If you  must  use  a  child  restra int  on  the

inspected  by your  authorized  Audi dealer . 
How  the  Advanced  Airbag  System 
components  work  together 
The front  Advanced  Airbag  System  and  the 
s ide  airbags  supp lement  the  protection  of
fered  by the  front  three-point  safety  belts 
with  pretensioners  and  load  limiters  and  the 
adjustable  head  rest raints  to  help  reduce  the 
risk of  inj ury in a wide  range  of  accident  and 
c rash  situations.  Be s ure  to  read  the  impor
tant  information  about  safety  and  heed  the 
WARNINGS in this  chapter. 
Deployment  of the  Adv a need  A irbag  System 
and  the  activation  of  the  safety  belt  preten
sioners  depend  on  the  deceleration  measured 
by the  crash  sensors  and  registered  by the 
electronic  control  unit.  Crash  severity  depends 
on  speed  and  deceleration  as  we ll as  the  mass 
and  stiffness  of the  veh icle  or  object  involved 
in the  crash . 
When  the  e lectronic  control  unit  registers  a 
low severity  crash  and  the  safety  belt  is  being 
used,  the  airbag  will  not  deploy.  If  the  safety 
belt  is  not  being  used,  the  first  stage  deploys, 
followed  by the  second  stage  after  a  much  lat er  t ime  in the  crash  sequence. 
If  the  electron ic control  unit  registers  a crash 
of  medium  severity , the  first  stage  of  the  air 
bag  deploys  followed  by the  second  stage  at  a 
much  later  time  in the  crash  sequence  -re
gardless  of  whether  the  safety  belt  is  be ing 
u sed  or  not . In  higher  sever ity  crashes  as  reg

Other  things  that  can affect  Advanced 
Airbag  performance 
Changing  the  vehicle's  suspension  system  can 
change  the  way that  the  Advanced  Airbag  Sys
tem  pe rforms  in a  crash.  For example,  using 
tire-r im  combinations  not  app roved  by Aud i, 
lowe ring  the  vehicle,  ch anging  the  stiffness  of 
the  suspension,  incl uding  the  springs,  s uspen
sion  struts,  shock  absorbers  etc.  can  change 
the  forces  that  are  measured  by the  ai rbag 
sensors  and  sent  to  the  electronic  control 
un it.  Some  suspension  changes  can,  for  exam
p le,  increase  the  force  levels  measured  by t he 
sensors  and  make  the  airbag  system  deploy  in 
crashes  in wh ich  it would  not  dep loy  if the 
cha nges  had  not  been  made.  Other  k inds  of 
cha nges  may  reduce  the  force  levels  meas
ure d by  the  sensors  and  preven t  the  a irbag 
from  deploying  when  it sho uld . 
The  senso rs  in the  safety  belt  buckle  fo r th e 
d river and  front  passe nger  sea t tell  the  elec
tronic  control  module  if the  safety  belt  is 
l atched  or  not.  I f the  safety  belt  is being  used, 
the  front  airbag  will deploy  at  a  slightly  high er  rate  of vehicle  deceleration  than  if the  safe
ty  belt  is not  being  used.  Therefore,  in a  par
ticular  collision,  it  is poss ible  that  an  airbag 
will  not  deploy  at  a seating  position  where  the  safety  belt  is being  used  but  will  inflate  at  the  position  where  t
he safety  be lt  is not  being 
used.  It  is  important  that  nothing  interfere 
with  the  safety  be lt  b uckles  so that  the  sen
sors  can  send  the  correct information  about 
safety  belt  use  to  the electronic  control  un it.

can  on ly help  to  protect  you  if you  are  wearing 
your  safety  be lt  and  wearing  it  properly.  This 
is another  reason  why  you  should  always  wear 
your  safety  be lts,  not  just  because  the  law  re
quires  you  to do  so¢

notes. 
It i s important  to  remember  that  wh ile  the 
supplementa l side  airbag  system  is designed 
to  reduce  the  likelihood  of  ser ious  injuries, 
other  injur ies,  for  example,  swelling,  bru is ing, 
and  mi nor  ab rasions  ca n also  be  assoc iated 
with  deployed  side  airbags . Remember  too, 
s ide  a irbags  w ill dep loy  only  once  and  only  in 
certain  kinds  of  accidents  - your  safety  belts  are  always  there  to  offer  protection. 
Vehicle  damage,  repair  costs  or  even  the  lack 
of  ve hicle  damage  are  no t necessa rily a n in di
cat ion  o f ove r-sensitive  or  failed  airbag  a ctiva
t ion . In  some  coll is ions,  both  front  and  side 
airbags  may  inflate . Remember  too,  that  air 
bags  will  deploy  only  once  and  only  in  certain 
k inds  of  co llisions  -yo ur safety  be lts  are  a l
ways  there  to  offer  protection  in those  acc i
den ts  in which  airbags  are  no t supposed  to 
deploy  or  when  they  have  a lready  deployed . 
The side  airbag  system  w ill n ot  deploy: 
- when  the  ignition  is tu rned  off 
- in  side  co llisions  when  the  acceleration 
meas ured  by the  sensor  is too  low 
- in front-end  collisions 
- in  rea r-end  col lisions 
- in rollove rs . 
In  some  types  o f accidents  the  front  airbags, 
s ide  curtain  airbags  and  s ide  a irbags  may  be 
triggered  together. 
_A WARNING 
- Safety  belts  and  the  airbag  system  wi ll 
only  provide  protection  w hen  occupants

- If  the  ai rbag  ind icator  light  comes  on 
when  t he  vehicle  is being  used,  have  the 
system  inspected  immediately  by your 
authorized  Audi  dealer . The  airbag  may

-Objects  between  you and the  airbag  can 
increase the  risk of  injury  in  an accident 
by interfering  with  the  way the  airbag 
unfolds  or  by being  pushed  into  you  as 
the  airbag  inflates . 
- Never place or  attach  accessories or 
other  objects  (such as cupholders,  tele
phone  brackets,  or  even large,  bulky 
objects)  on the  doors,  over or  near the 
area marked  "AIRBAG" on the  seat 
backrests. 
- Such objects  and  accessories can be
come dangerous  projectiles  and cause 
injury  when  the  supplemental  side air
bag deploys . 
- Never carry  any objects  or  pets  in the 
deployment  space between  them  and 
the  airbags  or  allow  children  or  other 
passengers to  travel  in this  position . 
- Always  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  side air
bag dep loyment  and can cause  personal 
injury  in an accident. 
- Always  prevent  the  side airbags  from  be
ing  damaged  by heavy objects  knocking 
against  or  hitting  the  sides of the  seat
backs. 
- The airbag  system  can only  be triggered 
once. 
If the  airbag  has been triggered, 
the  system  must  be replaced  by an au
thorized  Audi  dealership . 
- Damage (cracks, deep  scratches etc .) to 
the  original  seat  covers or to  the  seam in 
the  area of  the  side airbag  module  must 
always  be  repaired immediately  by an au
thorized  Audi  dealer . 
- If  children  are seated  improperly,  their 
risk  of  injury increases in the  case of  an 
accident ~ page  200,  Child Safety . 
- Never attempt  to  modify  any compo
nents  of  the  airbag  system  in any way . 
- In  a side  collision,  side airbags  will  not 
function  properly  if  sensors cannot  cor rectly  measure  increasing air pressure  in 
side the  doors when  air escapes through 
Airbag  system  197 
larger,  unclosed  openings  in  the  door

- Never drive with  interior  door  trim  pan
els removed . 
- Never drive  when  parts  have been  re
moved from  the  inside  door  panel  and 
the  open ings they  leave have not  been 
properly  closed. 
- Never  drive when  loudspeakers  in the 
doors  have been  removed unless the 
speaker holes have been  properly 
closed. 
- Always  make certain  that  openings  are 
covered or filled  if  additional  speakers 
or  other  equipment  is installed  in the  inside  door  panels. 
- Always  have work  on  the doors done  by 
an authorized  Audi  dealer  or  qualified

Side  curtain  airbags 
Description  of  side curtain  airbags 
The side  curtain  airbags  can provide  supple
mental  protection  to  properly  restrained  oc 
cupants . 
Fig. 202 Side  curta in a irbags,  driver's  s ide: locatio n 
The side c urtain  airbags  are located  on both 
sides of  the  interior  above the  front  and  rear 
side  windows ~ fig.  202 . They ar e identified 
by the  word  "AIRBAG" on the  windshield 
frame  and the  center  roof  pillar . 
The side curtain  airbag  system  supplements 
the  safety  belts  and can help  to  reduce the  risk of  injury  for  occupants'  heads and upper 
torso  on the  side of  the  vehicle  that  is struck 
in a side collision.  The side  cur tain airbag  ..,.  
Page 200 of 342

198  Airbag system 
inflates  in side  impacts  and  only when  the  ve
hicle acceleration  registered  by the  control 
unit  is high  enough.  If this  rate  is  below  the 
reference  value  programmed  into  the  contro l 
unit,  the  side  airbags  will not  be triggered, 
even  though  the  car  may  be  badly damaged  as 
a result  of the  collision . It  is not  possible  to 
define  an  airbag  triggering  range  that  will 
cover every possible  angle  of  impact,  since  the 
circ umstances  w ill vary cons iderably  between 
one  co llision and  another.  Important  factors 
include,  for  examp le,  the  nat ure  (hard  or  soft) 
of the  impacting  object,  the  angle  of  impact, 
vehicle  speed,  etc. 
c:> page  198,  How side  cur
tain  airbags  work. 
Aside from  their  normal  safety  function,  safe 
ty  belts  work to  he lp keep  the  driver  or front 
passenger  in position  in the  event  of  a co lli 
sion  so that  the  side  curta in airbags  can  pro
vide  protection. 
The airbag  system  is not  a substitute  for  your 
safety  belt.  Rather,  it is part  of  the  overall  oc
cupant  restraint  system  in your  ve hicle. Al
ways remember  that  the  airbag  system  can 
only help  to  protect  you  if you  are  wearing 
your  safety  belt  a nd wear ing  it  prope rly. Th is 
is ano ther  reason  why you  shou ld a lways wear 
your  safety  bel ts, not  just  beca use  the  law re 
qu ires you  to do  soc:>

It  is important  to  remember  that  whi le the 
side  curta in a irbag  system  is des igned  to  he lp 
redu ce the  like lihood  of serious  injuries,  othe r 
injuries,  fo r example,  swell ing,  bruising,  and 
minor  abrasions  can also  be  associated  wit h 
these  airbags  upon  deployment.  Remember 
too,  these  a irbags  w ill deploy  on ly once  and 
only in certain  kinds  of accidents  -your  safety 
be lts  are  a lways there  to  offer  protection . 
The side curtain  airbag  system  basically 
con sists of : 
-The electronic  control  module  and  external 
side  impact  sensors 
- The side  curtain  airbags  above  the  front  and  rear  side  w indows  - The airbag  indicator  light  in the  instrument 
panel 
T he  airbag  system  is  mon itore d elec tronically 
to  make  certain  i t  is func tioning  properly  at  all 
times . Each t ime you  turn  on the  ignition,  the 
airbag  system  indicator  light  will come  on for 
a few seconds  (sel f diagnostics). 
The  side curtain  airbag  is not  activated: 
- if the  ignition  is  turned  off 
- in side  co llision s whe n the  accele ration 
meas ured  by the  sensor  is too  low 
- in rear-end  col lisions . 
A WARNING 
-Safety  belts  and  the  airbag  system  will 
only provide  pro te ction  when  occupant s 
are  i n the  proper  seating  posi tion 
<=>page 71,  General recommendations. 
- If  th e airbag  ind ica tor  light  comes  on 
when  the  vehicle  is being  used,  have  the 
system  inspected  immediately  by you r 
authorized  Audi dealer . The s ide  curtain 
airbag  may  not  work  proper ly even when 
the  vehicle  acce lerat ion  in a s ide  collision 
is high  enough  to  activate  the  airbag. 
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 .

-Always  install  rear-facing  child  safety 
seats  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  does 
not  come  on  and  stay  on,  immediately 
install  the  rear-facing  child  safety  seat  in 
a  rear  seating  position  and  have  the  air
bag  system  inspected  immediately  by 
your  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  an  "Advanced 
Airbag  System"  in compliance  with  United 
States  Federal  Motor  Vehicle  Safety  Standard 
Child  Safety  201 
(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  si ze. 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  ..,.

202  Child  Saf ety 
seat.  The  weight  of  a  child  restraint  and  its 
"footprint"  vary for  different  kinds  of  chi ld  re
straints  and  for  the  d ifferent  models  of  the 
same  kind  of  child  restraint  offered  by child 
restraint  manufacturers . 
The  weight  ranges  for  the  individual  types,  makes  and  mode ls of  ch ild  restra ints  that  the 
NHTSA has  specified  in the  Safety  Standard 
together  with  the  weight  ranges  of  typical  in
fants  and  typical  1 year-old  child  have  been 
stored  in the  control  unit  of  the  Advanced  A ir
bag  System.  When  a  ch ild  restrai nt  is  being 
used  on  the  front  passenger  seat  with  a  typi 
cal  1 yea r-old  chi ld,  the  Advanced  Airbag  Sys
tem  compares  the  weight  measured  by the 
weight  sensing  mat  with  the  information  stor
ed  in the  electronic  contro l unit. 
The  electron ic cont rol  unit  a lso  registers  the 
tension  on  the  front  passenger  safety  belt. 
The  tension  on  the  safety  be lt  for  the  front 
passenger  seat  will  be  different  for  an  adult 
who  is properly  using  the  safety  belt  as  com
pared  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  be lt . T he  input  from  this  sen
sor  is then  used  with  the  we ight  to  "dec ide", 
whe ther  there  is a ch ild  restraint  w ith  a typ ica l 
1 year-o ld  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, 
make  sure  that  it  has  been  certified  to  meet 
United  States  Federal  Motor  Vehicle  Safety 
Standards  and  has  been  certified  by its  manu
facturer  for  use  w ith  an  airbag . Always  be  sure 
that  the  ch ild  restraint  is  p roperly  insta lled  at 
one  of  the  rear  seat ing  pos itions . If  in  excep
tional  c ircu mstances  you  must  use  it  on  the 
front  passenger  seat,  carefu lly read  all  of  the 
info rmation  on  c hild safety  and  Advanced  Air
bags  and  heed  a ll of  the  applicable  WARN
INGS.  Make  certain  that  the  child  restraint  is 
correctly  recognized  by the  weig ht-sensing  mat  inside  the  front  passenger  seat,  that  the 
front  passenger  airbag  is turned  off  and  that 
the  a irbag  status  is a lways  correct ly signa led 
by the 
PAS SENGER  AIR  BAG OFF light. 
Many  types  and  models  of  child  restraints 
have  been  available  over  the  years,  new  mod
els  are  introduced  regu larly  incorporating  new 
and  improved  des igns  and  o lder  models  are 
taken  out  of  product ion.  Ch ild  restraints  are 
not  standard ized . Child  restraints  of  the  same 
type  typically  have  d ifferent  weights  and  sizes 
and  different  'footpr ints,'  the  size  and  shape 
of  the  bo ttom  of  the  ch ild  restra int  that  sits 
o n  the  seat,  when  they  are  inst alled  on  a  vehi
cle  seat.  These  d ifferences  make  it v irtually 
impossible  to  certify  compliance  with  the  re 
quirements  for  advanced  airbags  with  each 
and  every  ch ild  restraint  that  has  ever  been 
sold  in the  past  or  will  be  sold  over  the  course  of  the  useful  life  of  your  veh icle. 
For this  reason,  the  United  States  National 
Highway  Traffic  Safety  Administrat ion  has 
published  a  list  of  spec ific type,  makes  and 
models  of  child  restraints  that  mus t be  used 
to  certify  comp liance  of  the  Advanced  Airbag 
System  i n your  veh icle  w ith  the  suppression 
requirements  of  Federal  Motor  Vehicle  Safety 
Standard  208.  These  chi ld  restraints  are :
