Fo r exa mple,  the  airbag  may  depl oy  if: 
-a small  child  that  is heavier  than  a typical  1 
year-o ld  child  is on  the  front  passenger  seat 
(regardless  of whether  the  child  is  in  one  of 
the  chi ld  seats  listed 
<!> page  171), or 
- a ch ild who  has  outgrown  child  rest raints  is 
on  the  front  passenger  seat. 
If the  front  passenger  airbag  is turned  off,  the 
P ASS ENGER  AIR  B AG OFF light  comes  on  in 
the  instrument  cluster  and  stays  on. 
If  the  front  passenger  airbag  deploys,  the 
Federal  Standard  requires  the  airbag  to  meet 
the  "low  risk"  deployment  criter ia to  reduce 
the  r isk  of  injury  through  interaction  with  the 
airbag.  "Low risk"  deployment  occurs  in those 
crashes  that  take  place  at  lower  decelerations 
as  defined  in the  electronic  control  unit 
r::> page  159,  PASSENGER AIR  BAG OFF light. 
Always remember,  a  chi ld  seat  or  infant  carri
er  insta lled  on  the  front  seat  may  be  struck 
and  knocked  out  of  position  by the  rapidly  in
flating  passenger's  airbag in a frontal  colli
sion.  The  airbag could  greatly  reduce  the ef
fectiveness  of the  child  restraint  and  even  se
riously  injure  the  child  during  inflat ion. 
For this  reason,  and  because  the  back  seat  is 
the  safest  place  for  children  - when  properly 
restrained  according  to  their  age  and  size  - we 
strongly  recommend  that  children  always  sit 
in the  back  seat 
r::> page  169,  Child  Safety . 
A WARNING 
A child  in a  rearward-facing  child  seat  in
stalled  on  the  front  passenger  seat  will  be 
ser iously  injured  and  can  be  killed  if the 
front  airbag  inflates  -even  with  an  Ad
vanced  Airbag  System . 
- T he  inflating  airbag  will  hit  the  child  seat 
or  infant  carrier  with  great  force  and  wi ll 
smash  the  child  seat  and  child  against 
the  backrest,  center  armrest,  door  or  roof. 
- Always  install  rear-facing  child  seats  on 
the  rear  seat. 
- If you  must  install  a  rearward  facing 
child  seat  on  the  front  passenger  seat

ately  install  the  rear-fac ing  child  seat  in a 
rear  seat ing  pos ition  and  have  the  airbag 
system  inspected  by your  A udi  dealer. 
- Forward-facing  child  seats  installed  on  the  front  passenger's  seat  may  interfere 
with  the  dep loyment  of the  a irbag  and 
cause  serious  persona l injury  to  the 
child. 
A WARNING 
If,  in except iona l circumstances,  you  must 
install  a  forward -facing  child  restraint  on 
the  front  passenger's  seat: 
- Always  ma ke  s ure  the  forward-facing 
seat  has  been  designed  and  certified  by  its  manufacturer  for  use  on  a front  seat 
with  a  passenger  front  and  s ide  a irbag. 
- Never  put  the  forward-facing  child  re
straint  up against  or  very  near  the  instru 
ment  panel. 
- Always move the passenge r seat into  its 
rearmost  pos ition  in the  seat's  fore  and 
aft  ad justment  range,  as  far  away  from 
the  airbag  as  possible  before  installing 
the  forward-fac ing  ch ild  restra int.  The 
backrest  must  be  adjusted  to  an  upright 
position. 
- Make sure  that  the 
PASSENGER AIR  BAG

A WARNING ,. 
If,  in  exceptional  c ircumstances,  you  must 
install  a forward  or  rearward-fac ing  child 
restraint  on  the  front  passenge r's  seat: 
- Improper  installation  of  child  restraints 
can  reduce  their  effectiveness  or  even 
prevent  them  from  providing  any  protec
t ion. 
- An improperly  installed  child  restraint 
can  interfere  with  the  airbag  as  it  de 
ploys  and  serio usly injure  or  even  kill the 
child  -even  wi th an  Advanced  Airbag 
System. 
- Always carefully  follow  the  manufactur
er's  instructions  provided  with  the  child 
seat  or  car rier . 
- Always  m ake su re  that  there  is  nothing 
on  the  front  passenger  seat  that  will 
cause  the  capacitive  passenger  detection 
system  in the  seat  to  s ignal  to  the  Airbag 
System  that  the  seat  is occupied  by a  person  when  it  is  not,  or to  signal  that  it 
is occupied  by someone  who  is  heavier 
than  the  pe rson  actually  s itting  on  the 
seat.  The  presence  of  additiona l objects 
cou ld  cause  the  passenger  front  airbag 
to  be  t urned  on  w hen  it  sho uld  be  off,  or 
cou ld  cause  the  ai rbag  to work  in a way 
that  is  different  from  the  way  it wou ld 
have  worked  without  the  object  on  the 
seat.

Your vehicle  is  equipped  with  an  "Advanced 
Airbag  System " in compliance  with  Un ited 
States  Federa l Motor  Veh icle  Safety  Standard 
(FMVSS) 208  as  applicable  at  the  time  you r 
vehicle  was  manufactured . The  safety  belts 
for  the  seats  have  "pretensioners"  that  help  to  take  slack  out  of the  belt  system.  The  pre
ten sioners  are  also  act ivated  by  the  electronic 
control  unit  for  the  airbag  system. 
T he  front  safety  belts  also  have  load  lim iters 
to  help  reduce  the  forces  applied  to  the  body 
in a  crash. 
The  airbag  for  the  driver  is in the  steering 
whee l hub 
c:> fig.  140 and  the  airbag  fo r the 
front  pas senger  is in the  instr ument  panel

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 ex tremely  important  for your  safety  and 
the  safety  of  your  passengers, especially  in 
fants  and small  children . 
A WARNING 
Never rely on airbags  alone for  protection. 
- Even when  they  deploy,  airbags  provide  only  supplemental  protection . 
- Airbag  work  most  effectively  when  used 
with  properly  worn  safety  belts . 
- Therefore,  always wear your  safety  belts 
and make sure that  everybody  in your  ve 
hicle  is properly  restrained . 
- Always  hold  the  steering  wheel  with  both 
hands on the  outside  of  the  steering 
wheel  rim  at  the  9:00  o'clock and  3:00 
o'clock  positions  to  help  reduce the  risk 
of  personal  injury  if the  driver's  airbag  in
flates. 
- Never  hold the  steering  wheel  at the  12 
o'clock  position  or with  your  hands any
where  inside the  steering  wheel  or  on the 
steering  wheel  hub.  Holding  the  steering 
wheel  the  wrong  way increases the  risk  of  severe  injury to  the  arms,  hands, and 
head if  the  driver  airbag  deploys . 
A WARNING 
Objects  between  you and the  airbag  will 
increase the  risk of  injury  in  a crash by in
terfering  with  the  way the  airbag  unfolds 
and/or  by being  pushed into you  as the  air
bag inflates. 
- Always  make sure  nothing  is in the  front 
airbag  deployment  zone that  could  be 
struck  by the  airbag  when  it  inflates. 
- Objects  in the  zone of  a deploying  airbag 
can  become projectiles  when  the  airbag 
deploys  and cause serious  personal  in
jury. 
- Never hold  things  in your  hands or  on 
your  lap when  the vehicle  is in  use . 
-
Airbag  system  151 
-Never place accessories or  other  objects 
(such as cup holders,  telephone  brackets, 
note  pads, navigation  systems,  or  things 
that  are  large, heavy, or  bulky)  on the 
doors;  never attach  then  to  the  doors  or 
the  windshield;  never place them  over or 
near or  attach  them  to  the area marked 
,,AIRBAG " on the  steering  wheel,  instru
ment  panel or  the seat  backrests;  never 
place them  between  these  areas and you 
or  any other  person  in the  vehicle. 
- Never attach  objects  to  the windshield 
above the  passenger front  airbag,  such 
as accessory GPS navigation  units  or  mu
sic players.  Such objects  could  cause seri
ous  injury  in a collision,  especially  when 
the  airbags  inflate. 
- Never recline  the  front  passenger seat to  transport  objects.  Items  can also  move 
into  the  deployment  area of  the  side  air 
bags or  the  front  airbag  during  breaking 
or  in  a sudden  maneuver . Objects  near 
the  airbags  can  fly dangerously  through 
the  passenger compartment  and cause 
injury,  particularly  when the  seat  is re
clined  and  the airbags  inflate. 
A WARNING 
-= 
A person  on the  front  passenger seat , es-
pecially  infants  and small  children,  will  re
ceive serious  injuries  and  can even be  kil
led 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  under  these  special  conditions  is impossible  in all  conceiva
ble situations  that may happen  during 
the  useful  life  of  your  vehicle. 
- The  Advanced Airbag  System  can deploy 
in accordance with  the  ,,low risk"  option 
for  3-and 6-year-old  children  under the

old  infant  restra ined  in one  of  the  for
ward  fac ing or  rearward-fac ing ch ild 
seats  with which your  vehicle  was  certi
fied  is on  the  front  passenger  seat  and 
the  other  conditions  for  airbag  deploy ment  are  met. 
- Acc ident  statist ics  have  shown  that  chil
dren  are  generally  safer  in the  rear  seat 
area  than  in the  front  seating  posit ion . 
- For their  own  safety,  all chi ldren,  espe
ci ally 12 years  and  younger,  sho uld a l

for  their  age  and  size . 
Advanced  front  airbag  system 
Your vehicle  is equipped  with  a front  Advanced 
Airbag  System  in compliance  with  United 
States  Federal  Motor Vehicle Safety  Standard 
208  as  applicable  at  the  time  your vehicle  was  manufactured. 
The front  Advanced Airbag System  supple ments  the  safety  belts  to  provide  addit ional 
protection  for  the  driver's  and  front  passeng
er's  heads  and  upper  bodies  in frontal  crashes . 
The airbags  inflate  only in frontal  impacts 
when  the  vehicle  dece le rat io n  is high  enoug h. 
The front  Advanced Airbag System  for  the 
fro nt  seat  occupants  is not  a substitute  for 
your  safety  belts . Rather,  it  is part  of the  over
a ll occupa nt  restraint  system  in your veh icle. 
A lways  remember  that  the  airbag  system  ca n 
on ly help  to  pro tect  you,  if you are  s itting  up 
right,  wearing  yo ur safety  belt  and  wearing  it 
properly.  This is why you and  yo ur passengers 
must  always  be  properly  restrained,  not  just 
beca use  the  law requires  you to  be. 
The Advanced Airbag  System  in your veh icle 
has  been  certified  to  meet  the  " low risk"  re
qu irements  for  3 and  6 year-o ld children  on 
the  passenger  side  and  very small  adu lts  on 
the  dr iver  side.  The  low  risk deployment  crite
ria are  intended  to  he lp reduce  the  risk of  in
jury  through  interaction  with  the  front  airbag  that  can occur, for  example,  by being  too 
close  to  the  steering  wheel  and  instr ument 
panel  when  the  airbag  inflates . 
In  add ition,  the system  has  been  cer tified  to 
comply  with  the  "s uppression"  requirements 
of the  Safety  Standard,  to  turn  off the  front 
airbag  for  infants  12  months  o ld and  younger 
who  are  restrained  on the  front  passenger 
seat  in child  restraints  that  are  listed  in the 
Standard 
c> page  171,  Child restraints  and 
Advanced  front  airbag  system . 
"Suppression"  requires  the  front  a irbag  on the 
passenger  side  to  be turned  off if: 
- a child  up to  abo ut  one  year  of age  is re
strained  on the  front  passenger  seat  in one 
of the  rear-fac ing or  forward-facing  infant 
restraints  listed  in Federal  Motor Vehicle 
Safety  Standard  208  with  which  the  Ad 
vanced  A irbag  System  in your  veh icle was 
cert ified . Fo r a listing  of the  chi ld restraints

old  restrained  in one  of  the  rear-facing  or 
forward-facing  infant  restraints  (listed  in 
Federal  Motor Vehicle Safety  Standard  208 
w ith  which  the  Advanced  A irbag  System  in 
your veh icle was  certified),  the  front  airbag

t h e  passenger  side  has  not  been  turned  off  by 
the  control  unit  and  can  deploy  if the  contro l 
u nit  senses  an  impact  that  meets  the  condi
t ions  stored  in its  memory.

of  a typical 1 year-old,  but  less  than  the 
weight  of a  small  adult,  the  front  airbag  on 
the  passenger  s ide  may  deploy  (the 
PASSEN· 
GER  AIR  BA G OFF 
light  does  not  come  on). 
For  example,  the  a irbag  may depl oy  if: 
- a small  child  that  is heavier  than  a typical 1 
year-o ld  child  is on  the  front  passenger  seat 
(regardless  of whether  the  child  is  in  one  of 
the  chi ld  seats  listed 
<!> page 171), 
-a ch ild who  has  outgrown  child  rest raints  is 
on  the  front  passenger  seat. 
I f the  front  passenger  airbag  is turned  off,  the 
PA SSENGER AIR  BAG OFF light  in  the  center 
of the  inst rument  panel  w ill come  on  and  stay 
on. 
If the  front  passenger  airbag  deploys,  the 
F ederal  Standard  requires  the  a irbag  to  meet 
the  " low  ris k"  deployment  criteria  to  help  re 
d uce  the  risk of  injury through  interaction 
with  the  airbag . "Low  risk"  deployment  occurs 
in those  crashes  that  take  place  at  lower  de
celerations  as  defined  in the  electronic  control

Alway s remember : Even though your  vehicle 
is equipped  with  Advanced  Airbags,  the  safest 
p lace  for  children  is properly  restrained  on  the 
back  seat.  Please  be  sure  to  read  the  impor
tant  information  in the  sect ions  that  follow 
and  be  sure  to  heed  all  of the  WARNINGS . 
A WARNING 
To reduce  the  risk of  injury  when  an  airbag 
inflates,  a lways  wear  safety  belts  prope rly. 
- If you  are  unrestrained,  lean ing forward, 
sitting  sideways  or  out  of  position  in any 
way, your  risk of  injury  is  much  higher. 
- You w ill also  receive  serious  injuries  and 
cou ld  even  be  killed  if you  are  up  against 
the  a irbag  or  too  close  to  it  when  it  in
fla tes  - even  with  an  Advanced  Airbag

seriously  injured  and  can  be  killed  if the 
front  airbag  inflates  - even  w ith  an  Ad
vanced  A irbag  System. 
- Altho ugh  the  Advanced  Airbag  System  in 
your  veh icle  is designed  to  turn  off  the 
front  airbag  when  a  rearward-facing  child  restraint  has  been  installed  on  the 
front  passenge r seat,  nobody  can  abso
lutely  guarantee  that  dep loyment  is im
possible  in all  conceivable  s ituations  that 
may  happen  dur ing  the  usef ul life  of your 
veh icle. 
- The  infla ting  airbag  will  h it  the  ch ild  seat 
or  infant  carrier  with  g reat  force  and  will 
smash  the  child  seat  and  child  against 
the  backrest,  center  armrest,  door,  or 
roof. 
- Always  install  rearward-facing  chi ld  re
straints  on  the  rear  seat. 
- If you  must  insta ll a  rearwa rd  fac ing 
child  seat  on  the  front  passenger  seat  because  of exceptional  circumstances 
and  the 
PASSENGER AIR  BAG OFF light 
does  not  come  on  and  stay  on,  immed i· 
ately  insta ll the  rear-fac ing  child  seat  in a 
rea r seat ing  pos ition  and  have  the  airbag 
system  inspected  by you r Audi dealer . 
A WARNING 
If, in except iona l circumstances,  you  must 
install  a  forward-facing  child  restraint  on 
the  front  passenge r's  seat: 
- Always  ma ke  sure  the  forward-facing 
seat  has  been  designed  and  cer tified  by 
its  manufacture r for  use  on  a  front  se at 
with  a  passenger  fron t and  s ide a irbag . 
- Never  put  the  fo rward-facing  child  re
straint  up against  or  ve ry near  the  instru

Advanced Airbag  System  components 
The front  passenger  seat  in your  vehicle  has  a 
l o t  of very  important  pa rts  of  the  Advanced 
A irbag  System  in  it.  These  parts  incl ude  the 
capacitive  passenger  detect ion  sys tem,  wir
ing,  brac kets,  and  more . The  cont ro l unit 
monitors  the  system  on  the  front  passenger 
seat  when  the  ign ition  is switched  on  and 
turns  the  airbag  indicator  light  on  w hen  a 
malfunction  i n the  one  of  the  system  compo
n ents  is detected 
c::;, page 159 . Because  the 
front  passenge r seat  contains  important  pa rts 
of  the  Advanced  Airbag  System,  you  must 
take  ca re  to  pr even t  it  from  be ing damaged. 
Damage  to  the  seat  may  preven t the  Ad 
vanced  A irbag  System  for the  front  passenger 
seat  from  doing  its job  in a crash . 
The front  Advanced Airbag  System 
consists of the  following: 
- Crash  senso rs  in the  front  o f the  veh icle  that 
measure  ve hicle acceleration/dece leration 
to  provide  information  to  the  Advanced  Air bag  System  abo ut  the  severity  of  the  crash . 
- An electronic  co ntro l unit,  with  i ntegrated 
c rash  sensors  for  f ront  and  side  impacts. 
The  cont ro l unit  "decides"  whether  to  fire  t
he  front  a irbags  based  on  the  in format ion 
received  from  the  crash  sensors.  The  contro l 
un it  also  "decides"  whether  the  sa fety  belt 
pretens ioners  sho uld  be  activated. 
- An Advanced  Airbag  with  gas  generator  fo r 
the  dr iver  inside  the  steering  wheel  hub. 
- An Advanced  Airbag  with  gas  gene rator  in
side  the  inst rument  panel  for  the  front  pas
senger. 
- A capacit ive  passenger  detection  system  un
derneath  the  front  passenger  seat  cover. 
This  system  measures  the  electrical  capac i
tance  of the  person  in the  seat.  The  informa
tion  registered  is se nt  cont inuous ly to  the 
elect ronic  control  un it  to  regu late  deploy
ment  of the  front  Advanced  A irbag  on  the

How the  Advanced Airbag  System 
components work  together 
The front  Advanced  Airbag  System  and  the 
side  airbags  supplement  the  protection  of
fered  by the  front  three-point  safety  be lts 
with  pretensioners  and  load  limiters  and  the 
adjustable  head  restra ints*  to  help  reduce  the 
risk of  injury  in a wide  range  of  acc ident  and 
crash  situat ions.  Be sure  to  read  the  impor
tant  information  abo ut  safety  and  heed  the 
WARNINGS in this  c hapter . 
Dep loyment  of  the  Advanced  Airbag  System 
and  the  activat ion  of  the  safety  be lt  preten
sioners  depend  on  the  dece lerat ion  meas ured 
by the  c rash  senso rs  and  regis tered  by the 
e lectronic  control  u nit.  Crash  sever ity  depends 
on  speed  and  deceleration  as  well  as  the  mass 
and  stiffness  of  the  vehicle  or object  involved 
i n  the  c rash. 
On the  passenger  side,  regard less  of safety

A WARNING 
To reduce  the  risk  of  injury  when  a n airbag 
inflates,  a lways wear  safety  belts  properly . 
- If  you  are  unrestrained,  lean ing  forward, 
sitting  sideways  or  out  of  position  in any 
way, your  risk  of  inj ury is much  higher. 
- You w ill also  receive  serious  injuries  and

the  a irbag  or too  close  to  it when  it  in- flates

Safety  be lts  are  important  to  he lp keep  front 
seat  occupants  in the  proper  seated  position 
so  that  a irbags  can  unfold  proper ly and  pro
vide  supplemental  protect ion  in a frontal  col
lis ion . 
The front  airbags  are  des igned  to  provide  ad
ditional  protection  for  the  chest  and  face  of 
the  driver  and  the  front  seat  passenger  when: 
- safety  belts  are  worn  proper ly, 
- the  seats  have  been  posi tioned  so  that  the 
occupant  is properly  seated  as  far  as  poss i
b le from  the  airbag , 
- and  for  ad justab le  head  restraints:  the  head 
restraints  have  been  properly  ad justed . 
B ec au se  airb ags  inflate  in the  bli nk of an  eye

or  have  p laced  on  the  seat  co uld  become  dan 
gerous  pro jecti les,  and  be  p ushed  into  you  if

When  an  airbag  deploys,  fine  dust  is  re leased. 
T his  is  no rma l and  is  not  caused  by a  fi re  in 
the  ve hicle . This  dust  is  made  up  mostly  of  a 
powder  used  to  lubricate  the  airbags  as  they 
deploy.  It  could  irr itate  skin . 
It  is important  to  remembe r that  while  the 
supplementa l airbag  system  is designed  to  re
duce  the  like lihood  of  serious  injur ies,  other 
injur ies,  for  examp le swelling,  bruising  and 
minor  abrasions,  can  also  happen  when  air-
bags  inflate . A irbags  do  not  protect  the  arms

or  the  lower  parts  of  the  body. Front  airbags 
supp lement  the  three-point  safety  belts  only 
in some frontal  collisions  in which  the  vehicle 
dece leration  is high  enough  to  deploy  the  air
bags. 
F ront  airbag s will  no t deplo y: 
- if  the  ignition  is switched  off  when  a crash 
occurs, 
- in  side collisions, 
- in  rear-end  collisions, 
- in  rollovers, 
- when  the  crash deceleration  measured  by 
the  a irbag  system  is  less than  the  m inimum 
threshold  needed for  airbag  deployment  as 
registered  by the  electronic  control  unit. 
The f ront  pas seng er  airbag  al so will  n ot 
deploy: 
- when  the  front  passenger seat  is not  occu
pied, 
- when  the  electrical  capac itance  measured  by 
the  capacitive  passenger  detect io n  system 
for  the  front  passenger  seat  indicates  that 
the  passenger side frontal  airbag  must  be  switched  off  by the  electronic  control  unit

A WARNING 
Sitting  in the  wrong  position  can increase 
the  risk of  serious  injury  in  crashes. 
- To reduce the  r isk of  injury  when  the  air
bags inflate,  the  driver  and  passengers 
must  always sit  in an upright  posit ion, 
must  not  lean against  or  place any part 
of  the ir body too  close to  the  area where 
the  a irbags are located. 
- Occupants who  a re unbelted,  out  of  posi
t ion or  too  close to  the  airbag  can be se
riously  injured  by an airbag  as it  unfolds 
with  great  force  in the  blink  of  an eye

seriously  injured  and  can be killed  if  the 
front  airbag  inflates  -even w ith  an Ad

- The inflating  airbag  will  hit  the  ch ild  seat 
or  infant  carrier  with  great  force  and will 
smash the  child  seat  and child  against 
the  backrest,  center  armrest,  door  or 
roof. 
- Always install  rear-fac ing ch ild seats on 
the  rear seat. 
- If  you  must  install  a rearward  fac ing 
child  seat on the  front  passenger  seat  because of  exceptional  circumstances 
and the

A WARNING 
r---------
O b j e cts between  you and the  airbag  will 
increase the  risk  of  injury  in a crash by in
terfering  with  the  way the  airbag  unfolds 
or by be ing pushed into you as the airbag 
inflates. 
- Never hold  things  in your  hands or on 
your  lap when  the  veh icle 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  air bags during  braking  or  other  sudden  ma
neuvers and become dangerous  projec
tiles  that  can cause ser ious personal  in
jury  if  the  a irbags inflate. 
- Never p lace or  attach  accesso ries o r oth
er objects  (such as cup holders,  te le
phone  b rac kets,  large,  heavy or  bulky  ob 
jects)  on the  doors,  over o r near the  area 
marked  "AIRBAG" on the  steering  wheel, 
instrument  panel,  seat  backrests  or  be
tween  those  areas and yourself . These 
objects  could  cause injury  in  a crash, es pecially  when  the  airbags  inflate. 
- Never recline the  front  passenger's seat 
to  transport  objects.  Items  can also 
move into  the  area of  the  s ide a irbag  or

by a person whe n it  in fa ct  is not,  o r th at 
the  person  on the  sea t  is he avie r than  he 
or  s he actually  is.  The change  in  electric 
capacitance  because of  such objects  can 
cause the  passenger front  airbag  to  be 
t ur ned on when  it  sho uld  be off,  or  can 
cause the  airbag  to  work  in  a way that  is 
different  from  the  way it  wou ld have 
worked  w ithout  ob jects on the  seat . 
- Always  make sure that  there  is nothing 
on the  front  passenge r seat that  will 
cause the  capaci tiv e  passenge r detection 
system  in the  s eat  to  s ignal  to  the  A irbag 
System that  t he seat  is occupied  by a
