Care, service and disposal  of the  airbags 
Parts  of  the  airbag  system  are  installed  at 
many  different  places  o n your  Audi . Insta lling, 
removing,  servicing  or  repa iring  a  part  in an 
area  of the  veh icle  can  damage  a  part  of  an 
airbag  system  a nd  prevent  that  system  from 
working  properly  in a  coll is ion. 
There  are  some  important  things  you  have  to 
know  to  make  sure  that th e  effectiveness  of 
the  system  w ill not  be  impaired  and  that dis
carded  components  do  not  cause  injury  or  pol -

A WARNING 
1
Improper  care,  servicing and  repair proce
dures  can increase  the  risk of personal  in 
jury 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.  Solvents  or 
cleaners  could damage  the  airbag  cover 
or change  the  stiffness  or strength  of the 
material  so that  the  airbag  cannot  de
ploy and  protect  properly. 
- Never repair, adjust,  or change  any parts 
of the  airbag  system. 
- All work on the  steering  wheel,  instru
ment  panel,  front  seats  or electrical  sys
tem  (including the  installation of audio 
equipment,  cellular  telephones  and  CB 
radios,  etc .) must  be performed  by a 
qualified  technician  who has  the  training 
and  special equipment  necessary. 
- For any work on the  airbag  system,  we 
strongly  recommend  that you see your 
authorized  Audi dealer  or qualified work
shop. 
- Never modify the  front  bumper  or parts 
of the  vehicle body . 
- Always make sure  that  the  side airbag 
can inflate  without  interference: 
- Never install  seat  covers or  replace
ment  upholstery  over the  front  seat
backs that  have not  been  specifically 
approved  by Audi. 
- Never  use additional  seat  cushions  that 
cover the  areas  where the  side airbags 
inflate. 
- Damage to  the  original  seat  covers or 
to  the  seam  in the  area  of the  side air bag  module  must  always be repaired 
Airbag  system  123 
immediately by an authorized  Audi 
dealer. 
- The airbag  system  can be activated  only 
once . After an airbag  has  inflated,  it 
must  be replaced  by an authori zed Audi 
dealer  or qualified  technician  who has 
the  technical  information,  training and 
special  equipment  necessary. 
- The airbag  system  can be deployed only 
once . After an airbag  has  been  deployed, 
it must  be replaced  with  new replace
ment  parts  designed and  approved  espe
cially for your Audi model  version . Re
placement  of  complete airbag  systems 
or airbag  components  must  be per
formed  by qualified workshops  only.  Make sure  that  any airbag  service action 
is entered  in your Audi Warranty 
& Main
t enance  booklet  under

124  Airbag system 
Other  things  that  can affect  Advanced 
Airbag  performance 
Changing  the  vehicle's  suspension  system  can 
change  the  way  that  the  Advanced  Airbag  Sys
tem  performs  in a crash.  For example,  using 
tire-r im combinations  not  approved by Audi, 
lowering  the  vehicle,  changing  the  stiffness  of 
the  suspension,  including  the  springs,  suspen
sion  strut s,  shock  absorbers  etc.  can  change 
the  forces  that  are  measured  by the  airbag  sensors  and  sent  to  the  electronic  control 
unit.  Some  suspension  changes  can,  for  example,  increase  the force  levels  measured  by the 
sensors  and  make  the  airbag  system  deploy  in 
crashes  in  which  it would  not  deploy  if  the 
changes  had  not  been  made.  Other  kinds  of 
changes  may  reduce  the  force levels  meas
ured  by  the  sensors  and  prevent the  airbag 
from  deploying  when  it  should . 
The  sensors  in the safety  belt buckle  for  the 
driver  and front  passenger  seat tell  the  elec
tronic  control  module  if the safety  belt  is 
latched  or  not . 
If 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 possible  that  an  airbag 
will not  deploy  at  a  seating  position  where  the 
safety  belt  is being  used  but  will  inflate  at  the 
position  where  the  safety belt  is not  being 
used. 
It is  important  that  nothing  interfere 
with  the  safety  belt  buckles so  that the sen
sors  can  send  the  correct  information  about 
safety  belt  use  to  the  electronic  control  unit . 
A WARNING 
Changing  the  vehicle's  suspension  includ
ing  use  of  unapproved  tire-rim  combina
tions  can change  Advanced  Airbag  per
formance  and  increase  the risk of  serious 
personal  injury in a  crash. 
- Never  install  suspension  components 
that  do not  have  the  same  performance 
characteristics  as  the  components  origi
nally  installed  on your  vehicle. 
- Never  use  tire-rim  combinations  that 
have  not  been  approved  by Audi. 
A WARNING 
-Items  stored  between  the  safety  belt 
buckle  and  the  center  console  can  cause 
the  sensors  in the  buckle  to  send  the 
wrong  information  to  the  electronic  con
trol  module  and  prevent  the  Advanced  Air
bag  System  from  working  properly. 
- Always  make  sure  that  nothing  can  inter
fere  with  the  safety  belt  buckles  and  that 
they  are  not  obstructed.

that  the  airbags  can  provide  s upplemental 
protection. 
The  airbag  system  is  not  a s ubst itute  for  yo ur 
safety  be lt.  Rathe r,  it  is part  of  the  overall  oc
cupant  restraint  system  in your  veh icle . Al
ways  remember  that  the  airbag  system  ca n 
only  help  to  protect  you  if you  are  wearing 
your  safety  belt  and  wearing  it  properly . This 
is why you  shou ld  always  wear  your  safety 
be lt,  not  just  because  the  law  requires  you  to 
do  soc::> 
page  102,  Why  safety  belts?. 
The  safety  belt  buck le for  the  driver  and  front 
seat  passenger  have  switches  that  tell  the  air bag  control  module  if the  safety  belt  is  being 
used  or  not . If  the  safety  belt  is  being  used, 
the  knee  airbag  will deploy  at  a  slightly  higher 
r ate  of decelera tion  than  if the  belt  is not  be
in g  used.  Therefore,  in a  par ticular  collision , it 
is poss ible  th at  an  airbag  will  not  deploy  at  a 
seating  position  where  the  safety  belt  is  being 
used  but  will  inflate  at  the  position  where  the 
safety  belt  is not  be ing  used. 
Remembe r too,  airbags  will deploy  only  once 
and  only  in  certain  kinds  of accidents  -your 
safety  belts  are  a lways  there  to  offer  protec 
tion  in those  acc idents  in which  airbags  are 
not  supposed  to  deploy  or when  they  have  al
ready  deployed,  for  example  when  your  vehi
cle  strikes  o r is struck  by another  after  the 
fi rst  coll is io n. 
This  is just  one  of t he  reasons  why an  a irbag  is 
not  a  substitute  for  the  safety  belt.  The  airbag 
system  works  most  effective ly when  used  with 
the  safety  belts.  Therefore,  always  wea r your 
safety  belts  correctly . 
It  is important  to  remember  that  while  the 
supp lemental  knee  airbag  system  is designed 
to  reduce  the  like lihood  of  serious  injur ies, 
o ther  injuries,  fo r example,  swel ling,  b rui sing, 
minor  abrasions  and  friction  burn s can  also 
oc cur when  an  airbag  infl ates. 
The  knee airbag  system  basically cons ists 
of : 
-The  elect roni c con trol  mod ule 
A irba g  sy stem  125 
- Two in flatable  ai rbags  (a irbag  and  gas  gen 
erator),  one  for  the  driver  and  o ne for  the 
front  passenger 
- The  a irbag  i ndicator  light  in the  instr ument 
panel 
The knee airbag  system will  not  deploy: 
- when  the  ignit ion  is tu rned  off 
- in frontal  collisions  when  the  deceleration 
meas ured  by the  cont ro l unit  is too  low 
- in  side  collisions 
- in  rear-end  collisions 
- in  rollovers 
- in  the  event  of  a system  malfunction  (warn-
ing/ind icator  light  is on)

A WARNING 
- Safety  belts  and  the  airbag  system  can 
only  provide  protection  w hen  occupa nts 
are  in the  proper  seating  position 
<::>page  118. 
- If  the  airbag  ind icator  light  comes  on 
when  the  vehicle  is  being  used,  have  the  sys tem  inspected  immediately  by your 
author ized  Audi dealer. 
How  knee airbags  work 
The risk of  injury  to  the  leg  area  can  be  re
duced  by  fully  deployed  knee  airbags.

-
The  knee  airbag  system  has  been  designed  so 
that  the  airbags  for  the  dr iver  and  fro nt  pas
senger  deploy  in  certain  but  not  all  frontal 
collisions . 
II>-

126  Airbag  sys te m 
If the  front  airbags  deploy, the  knee  airbags 
a lso deploy  in frontal  co llisions when  the  de 
p loyment  threshold  stored  in the  control  unit 
is met. 
When the  system  dep loys fill the  airbags  with 
a prope llant  gas,  and  inflate  between  the  low
er  part  of the  instrument  panel  and the  driver 
and  the  lower  part  of the  instrument  panel 
and  the  front  passenger 
<=> page  118,  fig.  122. 
Although  they  are  not  a soft  pillow, they  can 
"cush ion" the  impact  and  in this  way they  can 
he lp to  reduce the  r isk of  injury to  the  lower 
extremities. 
A ll of this  takes  place  i n the  blink of an eye, so 
fast  that  many  people  don't  even  realize that 
the  airbags  have deployed.  The a irbags  also 
inflate  with  a great  deal  of force and  it is  im
portant  for occupant  safety  that  noth ing 
should  be  in the ir way when  they  deploy. 
Fu lly inflated  airbags  in combination  with 
properly worn safety  belts  slow down and  lim
it the  occupant's  forward  movement  and  help 
to  reduce the  r isk of  injury. 
Important  safety  instructions  on the 
knee  airbag  system 
Airbags  are  only  supplemental  restraints.  Al
ways  wear  safety  belts  correctly  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 ir bags  to  provide supp lemental  protection . 
,&. WARNING 
An inflating  knee  airbag  can cause  ser ious 
injury. Wear ing sa fety  belts  inco rrectly and 
improper  seating  positions  increase  the 
r isk of serious  personal  injury and  death 
whenever  a veh icle is being  used. 
- The knee airbag  system  cannot  protect 
you properly if you are  seated  too  close 
to  any of the  airbag  locations.  When  ad
just ing their  seat  positions,  it  is impor
tant  that  both  the  driver and  the  front  passenge r keep their  upper  bodies  and  knees  at  the  following  m
inimum  safe 
distances: 
- at  least  10  inches  (25 cm) between  the 
chest  and the  stee ring wheel/inst ru
ment  panel. 
- at  leas t 4  inches  (10  cm) between  the 
knees  and  the  lower part  of the  instru
ment  panel. 
- The  risk of personal  injury increases  if 
you lean fo rward or to  the s ide,  or  if the 
seat  is improperly  posi tioned  and you are 
not wearing  yo ur safety  belt.  The risk in 
creases  even more  should  the  a irbag  de
ploy. 
- Always ma ke sure that  the  knee airbag 
can inf late  without  interference.  Objects 
between  yo u and the  airbag  can  increase 
the  risk of in jury in an accident  by  inter
fering w ith  the  way the  a irbag  deploys  or 
by being  pushed  into you as  the  airbag 
deploys. 
- Never let  anybody, espec ia lly children 
or anima ls in the  footwe ll in front  of 
the passenger seat. If the a irbag  de· 
ploys, th is can result  in serious  or fatal 
injur ies. 
- No objects  of any k ind shou ld be car
ried in the  footwell  area  in front  of the 
driver's or passenger's  seat.  Bulky ob
jects  (shopping  bags,  for example)  can  hamper  o r prevent  proper  deployment 
of the  airbag . Small objects  can be 
th rown thro ugh the  veh icle if the  air
bag  deploys and  injure yo u or your p as
sengers. 
- Make sure there  are  no cracks, deep 
scratches  or other  damage  in  the area  of 
the  instrument  panel where  the  knee air 
bags  are  located . 
- If  child ren are  incorrectly seated,  their 
risk of injury increases  in a collision

Side  airbags 
Description  of  side airbags 
The airbag system  can provide supplemental 
protection  to properly  restrained  front  seat  occupants . 
Fig. 12 6 Side a irbag  locat ion  in t he d river 's seat 
The s ide  a irbags  are  located  in the  sides  of  the 
front  sea t backrests ¢ 
fig.  126 facing  the 
doors.  They  are  identified  by the  word  "AIR
BAG". 
The  side  airbag  sy stem  ba sic ally  con sis ts  of: 
- th e e lectronic  control  module  and  exter nal 
s ide  impact  senso rs 
- the  two  side  airbags  located  in the  sides  of 
the  front  backrests 
- the  a irbag  warning  light  in the  instrument 
cluster . 
The  airbag  system  is  monitored  electron ically 
to  make  certain  that  it  is functioning  properly 
at  all times . Each time  you  turn  on  the  igni
tion,  the  airbag  system  indicato r light  will 
come  on  fo r a  few  seconds  (self  diagnosti cs) . 
The  s ide  airbag  system  supplements  the  safe
ty  belts  and  can  help  to  reduce  the  risk of  in
jury  to  the  dr iver's  and  front  passenger's  up
pe r torso  and  head  inj uries  on  the  side  of the 
veh icle  tha t  is  s truck  i n a  side  collision . The 
ai rbag  dep loys  only  in  side  impacts  and  only 
when  the  vehicle  acceleration  registered  by 
the  cont rol  unit  is high  e nough . If  t his  rate  is 
be low  the  reference  va lue  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  co llision . 
It is not 
possible  to  def ine  an  a irbag  tr igger ing  range

that  will cove r every  possib le  ang le  of  impact, 
since  the  circumstances  wi ll vary  cons iderably 
between  one  co llision  and  another.  Important 
factors  include,  for  examp le,  the  nature  (hard 
or  soft)  of  the  impacting  object,  the  angle  of  i mpact,  vehicle  speed,  etc.  ¢ 
page  128, Im 
portant  safety  instructions  on the  side  airbag  system . 
Aside  from  their  normal  safety  function,  safe
ty  belts  work  to  help  keep  the  drive r or  front 
passenger  in  position  in t he  event  of a  side 
collision  so  that  the  side  airbags  ca n provide 
protection . 
The  airbag  system  is 
not a  substitute  for  your 
safety  belt . Rather,  it  is  part  of the  overall  oc
cupant  restra int  system  in your  vehicle . A l
ways  remember  that  the  side  airbag  system 
c an  on ly help  to  pro te ct  yo u  if you  are  wearing 
your  safe ty  be lt  and  wea ring  i t 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¢ 
page  102,  Why safety 
belts? . 
It is 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 ising, 
and  minor  abrasions  can  also  be  associated 
with  deployed  side  airbags . Remember  too , 
s ide  a irbags  will  deploy  only  once  and  only  in 
ce rtain  kinds  of  accidents  -your  safety  belts 
a re a lways  the re to  offer  p rotection . 
Vehicle  damage,  repair  costs  o r even  t he  lack 
of ve hicle  damage  are  not  necessa rily a n in d i
cation  of ove r-s ensitive  o r failed  airbag  activa
t ion.  In  some  col lisio ns,  both  front  and  side 
airbags  may  in flate.  Remember  too,  that  air
bags  will deploy  only  once  and  on ly in ce rtain 
k inds  of  co llisions  -yo ur safety  belts  are  a l
ways  the re to  offer  protection  in those  acci
dents  in which  airbags  are  not  supposed  to 
deploy  or  when  they  have  a lready  deployed . 
The side  airbag  sy ste m will  not  deploy: 
- when  the  ignit ion  is turned  off 
- in  side  co llisions  whe n the  a ccelera tion 
meas ured  by t he  sensor  is too  low  
Page 130 of 236
128  Airbag system 
-in front -end  collisions 
- in  rear-end co llisions 
- in  ro llovers. 
In  some types  of  accidents  the  front  airbags 
and side a irbags may be triggered  together . 
A WARNING 
-Safety  belts  and the  a irbag  system  wi ll 
only  p rov ide protection  when  occupants 
are in the  proper  sea ting  posit ion 
¢page  128. 
- If  the  airbag  indicato r 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  ac
celeration  in a side co llision  is high 
enough  to  activate  the  airbag. 
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. 127 Inflated  side  air bags  on  left  side  of vehicle 
When  the  system  is triggered , the  airbag  is 
fi lled with  propellant  gas and  breaks through 
a seam  in the  seat  surface  area marked  "AIR
B AG". 
It expands between  the  side t rim  panel 
and the  passenger. In  order to  help  provide 
this  additiona l protection,  the  side airbag 
must  inflate  with in a fraction  of  a second  at 
very  high  speed and  with  great  force.  The sup
plemental  side airbag  could  injure you  if your 
seating  position  is not  proper  or  upright or if 
items  are  located in the area where  the  sup 
p lemental  side a irbag  expands . This appl ies 
especia lly to  childre n ¢ page  130,  Child Safe- ty
. Supplemental  side airbags  inflate  between 
the  occupant  and the door  panel on the  side 
of  the  vehicle  that  is  struck  in  certain side  col
li sion 
¢ fig.  12  7. 
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 deve lop when  the  airbag  de
ploys . This  is normal  and does not  mean  there 
is  a fire  in the  vehicle. 
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 accord ingly  to help  the 
safety  belts and airbags  do their  job  to  pro
vide  supplemental  protection . 
A WARNING 
-
An inflat ing s ide a irbag can cause se rious 
or fata l injury.  Improperly  wearing  safety 
bel ts and  imp roper  sea ting  positions  in
crease the  r isk of  se rious personal  injury 
and dea th whenever  a vehicle  is being 
used . 
- In order  to  reduce  the risk of  in jury w hen 
the  supplemental  side airbag  inflates: 
- Always sit  in  an upright  position  and 
never lean  aga inst the  area whe re the 
supplementa l side airbag  is located . 
- Never let  a child  or  anyone e lse rest 
their  head aga inst the  s ide trim  pane l 
i n the  area where  the  s upplementa l 
s ide airbag  inflates . 
- Always  make sure that  safety  be lts  are 
worn  correctly, 
- Do not  let  anyone  s itting  in the  front 
seat put  their  hand  or  any other  parts 
of  the ir body out  of  the  window. 
- Always make sure that  the  s ide airbag 
can inf late without  inte rfe rence.
