Child  restraints  on  the  front  seat  -some 
important  things  to  know 
- Be sure  to  read  the  important  information  and  head  the 
WARNINGS  for  important  details  about  children  and 
Advanced  Airbags :=> 
page  169. 
Even though  your  vehicle  is  equipped  with  an  Advanced  Airbag 
System,  make  certain  that  all  children,  especially  those  12 years  and 
younger,  always  ride  in  the  back  seat  properly  restrained  for  their  age and  size . 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  safety  seat.  It 
can  be a very  dangerous  place  for  an  infant  or  a child  in  a rearward 
facing  seat. 
The Advanced  Airbag  System  in  your  vehicle  has  been  certified  to 
comply  with  the  requirements  of  United  States  Federal  Motor 
Vehicle  Safety  Standard  208 as applicable  at  the  time  your  vehicle 
was  manufactured. 
The  Standard  requires  the  front  airbag  on  the  passenger  side  to  be 
turned  off  ("suppressed")  if  a child  up to  about  one  year  of  age 
restrained  in  one  of  the  rear-facing  or  forward-facing  infant 
restraints  listed  in  Federal  Motor  Vehicle  Safety  Standard  208 with 
which  the  Advanced  Airbag  System  in your  vehicle  was  certified  has  been  installed  on  the  front  passenger  seat.  For a listing  of  the  child 
restraints  that  were  used  to  certify  compliance  with  the  US Safety 
Standard => 
page 171. 
The PASSENGER  AIR  BAG OFF light in the  instrument  panel  tells  you 
when  the  front  Advanced  Airbag  on  the  passenger  side  has  been 
turned  off  by  the  electronic  control  unit. 
Each time  you  turn  on  the  ignition,  the 
PASSENGER  AIR  BAG OFF 
light  will  come  on  for  a few  seconds  and: 
•  will  stay  on  if  the  front  passenger  seat  is not  occupied, 
Controls  and  equip
ment  Safety  first  Vehicle  operation 
• 
will  stay  on  if  there  is a small  child  or  child  restraint  on  the  front 
passenger  seat, 
•  will  go  off  if  the  front  passenger  seat  is  occupied  by  an  adult  as 
registered  by the  weight-sensing  mat=> 
page  158, "Monitoring  the 
Advanced  Airbag  System" . 
The 
PASSENGER  AIR  BAG  OFF light  comes  on  when  the  control  unit 
detects  a total  weight  on  the  front  passenger  seat  that  requires  the 
front  airbag  to  be  turned  off. 
If  the  total  weight  on  the  front  passenger  seat  is  more  than  that  of 
a typical  1 year-old  child  but  less  than  the  weight  of  a small  adult, 
the  front  airbag  on  the  passenger  side  can  deploy (the 
PASSENGER 
AIR  BAG  OFF 
light  does  not  come  on).  If the PASSENGER  AIR  BAG 
OFF 
light  does  not  come  on,  the  front  airbag  on  the  passenger  side 
has  not  been  turned  off  by the  electronic  control  unit  and  can 
deploy  if  the  control  unit  senses  an  impact  that  meets  the  condi
tions  stored  in  its memory. 
For example,  the  airbag  may  deploy  if: 
• a small  child  that  is heavier  than  a typical  1 year -old  child  is  on 
the  front  passenger  seat  (regardless  of  whether  the  child  is in  one 
of  the  child  safety  seats  listed=> 
page 171), or 
•  a child  who  has  outgrown  child  restraints  is  on  the  front 
passenger  seat. 
If  the  front  passenger  airbag  is turned  off,  the 
PASSENGER  AIR  BAG 
OFF 
light  comes  on  in  the  instrument  cluster  and  stays  on. 
The  front  airbag  on  the  passenger  side  may 
not deploy  (the 
PASSENGER  AIR  BAG OFF light  does  not  illuminate  and  stay  lit) even 
if a small  adult  or teenager,  or a passenger  who  is not  sitting  upright 
with  their  back against  a non-reclined  backrest  with  their  feet  on  the 
vehicle  floor  in  front  of  the seat  is on  the  front  passenger  seat 
=> 
page  128, "Proper  seating  position  for  the  driver". 
If  the  front  passenger  airbag  deploys,  the  Federal Standard  requires 
the  airbag  to  meet  the  "low  risk"  deployment  criteria  to  reduce  the  risk  of  injury  through  interaction  with  the  airbag . "Low  risk"  deploy
ment  occurs  in  those  crashes  that  take  place  at  lower decelerations

Your  vehicle  is equipped  with  an  "Advanced  Airbag  System"  in 
compliance  with United  States  Federal  Motor  Vehicle  Safety Stan
dard  (FMVSS) 208 as applicable  at  the  time  your vehicle  was  manu
factured.  The  safety  belts  for the front  seats  have "pretensioners" 
that  help  to  take  slack  out  of  the  belt system.  The  pretensioners  are 
also  activated  by the  electronic  control  unit  for the  airbag  system . 
The  front  safety  belts  also  have  load  limiters  to help  reduce  the 
forces  applied  to  the  body  in  a crash. 
The airbag  for  the driver  is  in the  steering  wheel hub~ fig. 
143 and 
the  airbag  for  the front  passenger  is  in  the  instrument  panel 
~ fig. 144. The  general  location  of  the  airbags  is  marked  "AIRBAG". 
There  is a lot you  need  to  know  about the airbags  in your  vehicle.  We 
urg e you  to  read  the  detailed  information  about  airbags,  safety  belts 
and  child  safety  in  this and the other  chapters  that  make  up  the 
owner's  literature.  Please be  sure  to  heed  the  WARNINGS  -they  are 
extremely  important  for your  safety  and the  safety  of  your  passen
gers,  especially  infants  and  small  children.

ARN ING  (continued ) 
• Airbag  work  most  effectively  when  used with  properly  worn 
safety  belt s. 
•  Therefore , always  wear  your  safety  belts  and  make  sure that 
everybody  in your  vehicle  is properly  restra ined . 
& WARNING 
A person on the  front  passenger  seat , espe cially  infants  and  small 
c hildren,  will  receive  serious  injuries  and  can  even  be  killed  by 
being  too  close to  the  airbag  when  it  inflates . 
•  Although  the  Advanced  Airbag  System  in your  vehicle  is 
designed  to  turn  off  the  front  passenger  airbag  if  an  infant  or  a 
small  child  is on the  front  passenger  seat , nobody  can  absolutely 
guarantee  that  deployment  unde r these  spe cial  conditions  is 
impossible  in all  conce ivable  situations  that  may  happen  during 
the useful life of your vehicle. 
•  The  Advanced  Airbag  System  can  deploy  in  accordance  with 
the  "low  risk" option  under the  U .S . Federal Standa rd if a child that 
is heavier  than  the  typical  one -year  old  child  is on the  front 
pas senger  seat  and  the  other  cond itions  for  airbag  deployment 
are  met. 
•  Accident  statistics  have shown  that  children are generally  safer 
in the  rear  seat  area  than  in the  front  seating  position . 
•  For their  own  safety , all  children , espec ially  12  years  and 
younger,  should  always  ride  in the  back  properly  restrained  for 
their  age  and  size . •

& WARNING (continued) 
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  airbag  system  inspected 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. 
•  Never  put  the  forward-facing  child  restraint  up against  or very 
near  the  instrument  panel . 
•  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  forward-facing  child 
restraint . The  backrest  must  be  adjusted  to  an  upright  position. 
•  Make  sure that  the  PASSENGER AIR BAG OFF light  comes  on 
and  stays  on all the  time  whenever  the  ignition  is switched  on.  • 
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-sensing  mat,  sensors,  wiring,  brackets,  and  more.  The  func
tion  of  the  system  in  the front  passenger  seat  is  checked  by  the  elec 
tronic  control  unit  when  the ignition  is on.  The  control  unit  monitors 
the  Advanced  Airbag  System  and  turns  the  airbag  indicator  light  on 
when  a  malfunction  in  the  system  components  is detected.  The 
function  of  the  airbag  indicator  light is  described  in greater  detail 
below.  Because  the  front passenger  seat  contains  important  parts 
of  the  Advanced  Airbag  System, you  must  take  care  to  prevent  it from  being  damaged. 
Damage to  the  seat  may  prevent  the 
Advanced  Airbag  for  the  front  passenger  seat  from  doing its  job  in 
a  crash . 
The  front  Advanced  Airbag  System  consists  of  the 
following:  •  Crash  sensors  in  the  front  of  the vehicle  that  measure vehicle 
acceleration/deceleration  to provide  information  to the  Advanced 
Airbag  System  about  the  severity  of  the crash. 
•  An  electronic  control  unit,  with  integrated  crash  sensors  for  front 
and  side  impacts.  The  control  unit "decides"  whether  to  fire the 
front  airbags  based  on  the informa tion received  from  the crash 
sensors.  The  control  unit also  "decides"  whether  the safety  belt 
pretensioners  should  be  activated. 
•  An  Advanced  Airbag  with  gas  generator  for the  driver  inside  the 
steering  wheel  hub . 
•  An  Advanced  Airbag  with  gas  generator  inside  the instrument 
panel  for  the  front  passenger. 
•  A weight-sensing  mat  under  the  upholstery  padding  of  the  front 
passenger  seat  cushion  that  measures  the  total weight  on  the  seat. 
The  information  registered  is  sent  continuously to  the  electronic 
control  unit  to regulate  deployment  of  the front  Advanced  Airbag  on

belt  is  not  being  used,  the  first  stage  deploys,  followed  by  the 
second stage after  a much  la ter  time  in  the  crash  sequence. 
If the  electronic  control  unit  registers  a crash  of  medium  severity, 
the  first  stage  of the  airbag  deploys  followed  by the  second  stage  at  a  much  later  time  in the  crash  sequence  -regardless  of  whether  the 
safety  belt  is  being  used  or  not . In  higher  severity  crashes  as regis 
tered  by the  e lectronic  contro l unit,  both  the first  and  second  stages 
deploy  almost  at  the  same  time. 
On the  passenger  side,  regardless  of  safety  belt use, the  airbag  will 
be  turned  off  if the  weight  on  the  passenger  seat  is  less than  the 
amount  programmed  in the  electronic  control  unit . The front  airbag 
on  the  passenger  side  will also  be  turned off if one  of  the  ch ild 
safety  seats  that  has been  certified  under  Federal Motor Vehicle 
Safety  Standard  208  has been  recognized  on the  seat.  The 
PASSENGER AIR BAG OFF  light  comes  on  and  stays  on  to  tel l you 
when  the front  Advanced  Airbag  on the  passenger  s ide has  been 
turned  off=> 
page  149, "Child  restraints  on  the  front  seat  - some 
i m portant  things  to  know". 
& WARNING 
To reduce  the  risk  of  injury  when  an  airbag inflates, always  wear 
safety  belts  properly . 
•  If you  are unrestrained , leaning forward , sitting  sideways  or  out 
of  position  in  any way, your  risk of injury  is much  higher. 
•  You  will  also  receive serious  injuries and  could  even  be killed  if 
you  are  up  against  the  airbag  or  too  close to  it  when it  inflates  -
even with  an Advanced  Airbag=>

More  important  things  to  knovv  about  front 
airbags 
Fig . 145  Inflated  front 
airbags 
Safety  belts  are  important  to  help  keep  front  seat  occupants  in  the 
proper  seated position  so that  airbags  can  unfold properly  and 
provide  supp lemental  protection  in  a fronta l collision. 
The  front  airbags  are  designed  to  provide  additional protection  for 
the  chest  and  face  of  the  driver  and  the  front  seat  passenger  when: 
•  safety  be lts  are  worn  properly, 
•  the  seats  have  been  positioned  so that  the  occupant  is  properly 
seated  as far  as  possible from the airbag, 
•  and  the  head  restraints  have  been  properly  adjusted. 
Because  airbags  inflate  in  the blink  of an eye with  great  force,  things 
you  have  on  your  lap  or  have placed  on  the  seat  cou ld  become 
dangerous  projectiles,  and  be  pushed  into you  if  the  airbag  inflates . 
When  an  airbag  deploys,  fine  dust is released.  This  is normal  and  is 
not  caused  by a fire  in  the  vehic le.  This  dust  is made  up  most ly of  a 
powder  used to lubricate  the airbags  as  they  deploy.  It  could irritate 
skin. 
It  is  important  to  remember  that  while  the  supplemental  airbag 
system  is designed  to  reduce  the  likelihood  of  serious  injuries,  other 
injuries,  for  example  swelling,  bruising  and  minor  abrasions,  can 
also  happen  when  airbags  inflate . Airbags  do  not  protect  the  arms ._,

poi nt  s afet y be lts o nly  in  s ome fro ntal c oll isi ons  i n whi ch the  v ehicl e 
deceleration  is  hi gh enough  to  d eploy  the  airbags . 
Front  airbags will not  deploy: 
• if  the  ignition  is  switched  off  when  a crash  occurs, 
•  i n  sid e  collisi ons, 
•  in  r ear- e nd  collisions ,

& WARNING 
Sitting  in the  wrong  position  can  increase  the  risk  of  serious  injury 
in  crashes . 
•  To reduce  the  risk  of  injury  when  the  airbags  inflate , the  driver 
and  passengers  must  always  sit  in  an  upright  position , must  not 
lean  against  or  place  any  part  of  their  body  too  close  to  the  area 
where  the  airbags  are  located . 
•  Occupants  who  are  unbelted , out  of  position  or  too  close  to  the 
airbag  can  be  seriously  injured  by  an  airbag  as  it  unfolds  with 
great  force  in  the  blink  of  an  eye~ page

& WARNING 
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  inflates  - 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  arm  rest , door  or  roof. 
•  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  because  of  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  airbag  system  inspected  by  your 
authorized  Audi  dealer . 
& WARNING 
Objects  between  you  and  the  airbag  will  in crease  the  risk  of  injury 
in  a crash  by  interfering  with  the  way  the  airbag  unfolds  or  by 
being  pushed  into  you  as the  airbag  inflates . 
•  Never  hold  things  in your  hands  or  on  your  lap  when  the  vehicle 
is  in  use. 
•  Never  transport  items  on  or  in  the  area  of  the  front  passenger 
seat.  Objects  could  move  into  the  area  of  the  front  airbags  during 
braking  or  other  sudden  maneuvers  and  become  dangerous 
projectiles  that  can  cause  serious  personal  injury  if  the  airbags 
inflate . 
•  Never  place  or  attach  accessories  or  other  objects  (such  as cup 
holders,  telephone  brackets , large,  heavy  or  bulky  objects)  on  the 
doors , over  or  near  the  area  marked  "AIRBAG " on  the  steering 
wheel , instrument  panel , seat  backrests  or  between  those  areas 
and  yourself . These  objects  could  cause  injury  in  a  crash , espe-
cially  when  the  airbags  inflate .  ...
