with  the  vehicle  interior  has  all  the  energy 
they  had  just  before  the  crash. 
Never  rely  on  airbags  a lone  for  protection. 
E ven  when  they  deploy,  airbags  provide  only 
additional  protection . Ai rbags  are  not  sup
posed  to  deploy  in  all  kinds  of accidents.  Al
though  your  Audi  is  equipped  with  a irbags,  all 
veh icle  occupants,  including  the  driver , must 
wear  safety  belts  correctly  in order  to  mini mize  t he  risk of  severe  injury  or  death  in a 
crash . 
Remember  too,  that  airbags  wi ll deploy  on ly 
once  and  that  your  safety  belts  are  always 
there  to  offer  protection  in those  accidents  in 
which  airbags  are  not  supposed  to  deploy  or 
when  they  have  a lready  deployed . Unbelted 
occupants  ca n also  be  thrown  out  of  the  vehi
cle  whe re  even  more  severe  or  fa tal  in ju ries 
can  occur . 
It is  also  impo rtant  fo r the  rear  passenge rs  to 
wear  safety  belts  correctly.  Unbe lted  passen
ge rs  in the  rea r seats  endanger  no t on ly  them

Safety  belts  protect 
People think  it 's possible  to  use the  hands  to 
brace  the  body  in  a minor  collision.  It 's simply 
not  true! 
F ig . 1 47 Driver  is correctly  restra ined  in a sudden  bral<·

Safety  belts  used  properly  can  make  a  big  dif
ference . Safety  be lts  he lp to  keep  passengers 
in their  seats,  gradually  reduce  energy  levels 
Safety  belts  139 
applied  to  the  body  in an  accident,  and  he lp 
prevent  the  uncontrolled  movement  that  can 
ca use  serio us injuries . In  addition,  safety  be lts 
reduce  the  danger  of  being  thrown  out  of the 
vehicle. 
Safety  be lts  attach  passengers  to  the  car  and 
give t hem  the  benefit  of  being  s lowed  down 
more  gently  or  "softly"  through  the  "give"  in 
the  safety  belts,  crush  zones  and  other  safety 
features  enginee red  into  today's  vehicles.  By 
"absorbing"  t he  kinetic  energy  over  a  longer 
per iod  of t ime,  the  safety  be lts make  the 
fo rces  on  the  body  more  "tolerable"  and  less 
li kely to  ca use  inju ry. 
Althoug h these  examples  a re  based  o n a fron
ta l co llision,  safety  belts  can  a lso  substantia l
l y reduce  the  risk  of  in jury in other  kinds  of 
cr ashes.  So, whethe r you're  on  a  long  trip  o r 
just  going  to the  co rner  store,  a lways  buckle 
u p and  make  sure  others  do,  too . Accident  sta 
tistics  show  that  vehicle  occupants  properly 
wearing  safety  belts  have  a  lower  risk of  be ing 
i njured  and  a  much  better  chance  of surviving 
an  accident.  Properly  using  safety  belts  also 
greatly  increases  the  ability  of  the  supplemen 
ta l airbags  to  do  the ir job  in a  collision . Fo r 
th is  reason,  wearing  a safety  belt  is  legally  re
quired  in  mos t countries  including  much  of 
t he  United  States  and  Canada. 
Althoug h your  Aud i is equipped  wi th a irbags, 
you  st ill have  to  wear  the  safety  belts  p rov id
ed . Front  airbags,  fo r example,  a re  activa ted 
o nly in some  frontal  collisions.  The front  a ir
bags  are  not  act ivated  in a ll frontal  coll isions, 
in s ide  and  rear  co llisions,  in  roll  ove rs or  in 
cases  where  t here  is  not  eno ugh  deceleration 
through  impact  to  the  front  of the  veh icle. 
The  same  goes  for  the  other  a irbag  systems  in 
your  Audi . So,  always  wear  your  safety  belt 
and  make  su re everybody  in your  veh icle  is 
properly  restrai ned!

Wearing  safety  belts  improperly  can  cause  se
rious  injury or  death.  Safety  belts  can  only 
work  when  they  are  correctly  positioned  on

How safety  belt  pretensioners  work 
In front , side  and  rear -end  collisions above  a 
particular  severity,  safety  belts  are tensioned  automatically. 
The  safety  belts  are  equipped  with  safety  belt 
pretensioners . The  system  is activated  by sen
sors  in front,  side  and  rear-end  co llisions  of 
great  seve rity . This tightens  the  belt  and  takes

up  the  slack  helps  to  reduce  forward  occupant 
movement  during  a  collision. 
{[)  Note 
Never  let the  belt  remain over  a  rear  seat
back  that  has  been  folded  forward. 
(D Tips 
The  safety  belt  pretensioner  can  only  be  activated  once. 
- In  minor  frontal  and side  collisions,  in 
rear-end  collisions,  in  a  rollover  and  in 
accidents  involving  very  little  impact 
force,  the  safety  belt  pretensioner  are 
not  activated. 
- In  the  case  of  a side  crash,  the  safety 
belt  pretensioners  will activate  on  the 
driver's  or front  passenger's  sides  only, 
depending  on  which  side  of  the  vehicle 
the  crash  occurs . 
- When  the  safety  belt  pretensioners  are 
activated,  a fine  dust  is released.  This  is 
normal  and  is not  caused  by a fire  in the 
vehicle. 
- The  relevant  safety  requirements  must 
be  observed  when  the  vehicle  or  compo 
nents  of  the system  are  scrapped . An au
thorized  Audi  dealer  or  qualified  work
shop  is  familiar  with  these  regulations 
and  will  be  pleased  to  pass  on  the  infor
mation  to  you. 
- Be  sure to observe  all  safety,  environ
mental  and  other  regulations if the  vehi
cle  or  individual  parts  of the  system,  par
ticularly  the  safety  belt or airbag,  are  to 
be  disposed.  We  recommend  you  have 
your  authori zed  Audi  dealer  perform  this 
service  for  you . 
Service and  disposal of  safety  belt 
pretensioner 
The  safety  belt  pretensioners  are  parts  of  the

There  are  some  important  things  you  have  to 
know  to  make  sure  that  the  effectiveness  of 
the  system  will  not  be  impaired  and  that  dis
carded  components  do  not  cause  injury  or  pol
lute  the  environment. 
A WARNING 
Improper  care,  servicing  and  repair proce
dures  can  increase  the  risk of  personal  in
jury  and  death  by preventing  a  safety  belt 
pretensioner  from  activating  when  needed 
or  activating  it  unexpectedly : 
- The  belt  pretensioner  system  can  be  acti 
vated  only  once . If  belt  pretensioners 
have  been  activated,  the  system  must be

Airbag  system Important  things  to know 
Importance  of  wearing  safety  belts  and 
sitting  properly 
Airbags  are only supplemental  restraints.  For 
airbags  to do their job , occupants  must  al
ways properly  wear  their safety  belts  and  be 
in a proper  seating  position. 
For  your  safety  and  the  safety  of  your  passen
gers,  before  driving off,  always: 
""  Adjust  the driver's  seat  and  steering wheel 
properly ¢ 
page 128, 
"" Adjust  the  front  passenger's seat  properly 
¢page  59, 
""  Wear  safety  be lts  properly ¢ page  140, 
"" Always  properly  use  the  proper  child  re-
straint  to  protect  chi ldren ¢ 
page  166. 
In  a collision  airbags  must  inflate within  th e 
blink  of  an  eye  and  with  considerable  force. 
The  supplemental  airbags  can  cause  injuries  if 
the  driver  or  the  front  seat  passenger  is not 
seated  properly . Th erefore  in  order  to help  the 
a ir bag  to  do  its job,  it  is  important,  both  as  a 
driver  and  as  a  passenger to  s it properly  at  all 
times. 
By keeping  room  between  your  body  and the 
steering  wheel  and  the  front of the  passenger 
compartment,  the airbag  can  inflate  fully  and 
comp letely  and  provide  supplemental  protec
tion  in certain  frontal  collisions ¢

whee l and  the driver  and  between  the  instru
ment  panel  and  the  front  passenger.  The  air
bags  will  deflate  immediately  after  deploy
ment  so  that  the  front  occupants  can  see 
through  the  windshield  aga in without  inter
ruption . 
All of  th is  takes  place  in the  blink  of  an  eye,  so 
fast  that  many  people  don 't  even  realize  that 
the  air bags  have  deployed . The  airbags  also 
inflate  with  a  great  deal of  force  and  noth ing 
shou ld be  in  their way when  they  deploy. 
Front  airbags  in combination  with  properly 
worn  safety  belts slow  down  and  limit  the  oc 
cupant's  forward movement.  Together  they 
help  to  prevent  the driver  and  front  seat  pas
senge r from  hitting  parts  of  the  inside the  ve
hicle  while  reducing the  forces  acting  on the 
occupant  dur ing  the  crash.  In  this  way they 
help  to  reduce the  risk  of  injury  to  the  head 
and  upper  body  in the  crash . A irbags  do  not 
protect  the  arms or the  lower  parts  of  the 
body . 
Both  front  air bags  w ill not  inflate  in  all  frontal 
collisions . The  triggering  of the  air bag  system 
depends  on  the  vehicle  deceleration rate 
caused  by the  collision  and  registered  by the 
electron ic control  unit. 
If this  rate  is  below 
the  reference  value  programmed into  the con
trol  unit,  the  airbags  will  not  be triggered, 
ev en though  the  car  may  be  bad ly damaged  as 
a  resu lt  of  the  co llision . Vehicle  damage,  re
pair  costs  or  even  the  lack of  ve hicle  damage 
is  no t necessarily  an  indication  of  whether  an 
airbag  should  inflate  or  not . 
It  is  not  possib le  to  define  a  range of  vehicle 
speeds  that  w ill cover  every  possib le  kind  and  ..,.

angle  of  im pact  that  will always  trig ger  the 
airbags,  since  the  circumstances  wi ll vary  con
siderably  between  one  collision  and  another. 
Important  factors  include,  for  example,  the 
nature  (hard  or  s oft)  of the  object  which  the 
car  h its,  the  angle  of  impact,  vehicle  speed, 
etc.  The  front  airbags  will also  not  inflate  in 
side  or  re ar collisions,  or  in  roll-overs . 
Always remember : Airbags  will deploy  only 
once,  and  only  in certa in  kinds  of  collisions . 
Your safety  belts  are  always  there  to  offe r pro
tection  in those  s ituations  in which  airbags 
a re  not  supposed  to  deploy , or  when  they  have 
a lready  deployed;  for  example , when  yo ur ve
h icle  strikes  or  is  st ruck  by another  after  the 
first  collision . 
This  is just  one  of the  reaso ns why  an  a irbag  is 
a  supplementary  restra int  and  is not  a  s ubst i
tute  for  a  safety  be lt.  The  airbag  system 
works  most  effective ly when  used  with  the 
safety  be lts.  Therefore,  always  properly  wear 
you r safety  belts ¢ 
page  137 . 
A WARNING 
Sitting  too  close  to  the  steer ing  wheel  or 
instrument  panel  will decrease  the  effec
tiveness  of  the  airbags  and  will  increase 
the  risk of  pe rsonal  injury  in a  collision . 
- Never  sit  closer  than  10  inches  (25  cm) 
to  the  stee ring  wheel  or  instr ument  pan
el. 
- If you  cannot  sit  more  than  10  inches 
(25  cm) from  t he  steer ing  wheel,  investi
gate  whethe r adaptive  equipment  may 
be  available  to  help  you  reach  the  pedals 
and  incre ase  your  sea ting  dis tance  from 
the  steering  wheel. 
- If you  are  unrestr ained,  lean ing  fo rward, 
s itting  sideways  or  out  of  posi tion  in any 
way, your  risk  of  injury  is much  higher. 
- Yo u w il l a lso  receive  serio us in juries  and 
co uld  even  be  killed  if you  are  up  against 
the  airbag  or  too  close  to  it when  it  in 
flates  -even  with  an  Advanced  Airbag. 
- To  reduce  the  r is k  of  i njury  when  an  air 
bag  inf lates,  a lways  wear  safety  belts 
properly 
c::> page  140,  Safety  belts . 
-Always make  certain  that  ch ild ren  age  12 
or younger  always  ride  in the  rear  seat.  If 
children  are  not  properly  restrained,  they 
may  be  severe ly injured  or  killed  when  an 
airbag  inflates . 
- Never  let  c hildren  ride  unrestrained  or 
improperly  restrained  in the  vehicle . Ad
just  the  front  seats  prope rly . 
- Never  ride  with  the  back rest  reclined. 
- Always  sit  as  far  as  possible  from  the 
steer ing  whee l or the  instrument  pane l 
¢page  128. 
-Always  sit  upright  with  your  back  against 
the  backrest  of your  seat. 
- Never  p lace  your  feet  on  the  instrument 
panel  or  on  the  seat.  Always  keep  both 
feet  on  the  floor  in front  of  the  seat  to 
he lp prevent  serious  in ju ries  to  the  legs 
and  h ips  if the  airbag  inflates . 
- Never  recline  the  front  passenger 's seat 
to  transport  objects . Items  can  a lso 
move  i nto  the  a rea  of  the  s ide  airbag  or 
the  front  a irbag  d uring  br akin g  or  in a 
sudden  maneuve r. Obje cts  ne ar the  air 
bags  can  become  projec tiles  and  cause 
inj ury when  an  airbag  inflates.

Even though your  vehicle is equipped  with  an 
Advanced  Airbag  System,  make  certain  that 
all  ch ildren,  especially  those  12  years  and 
younger,  a lways  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  veh icle 
has  been  certified  to comply  w ith  the  Requ ire
ments  of  United  States  Federa l Motor  Vehicle 
Safety  Standard  208 as applicable  at  the  time 
your  vehicle  was  manufactured. 
The  Standard  requires  the front  ai rbag  on  the 
passenger  side  to  be turned  off  ("sup
p ressed")  if  a ch ild  up to  about  one  year of 
age  restrained  in one  of the  rear-facing or for
ward -facing  infant  restraints  listed  in  Federal 
Motor  Vehicle  Safety  Standard  208  with  wh ich 
the  Advanced  Airbag  System  in your  vehicle 
was  certified  has  been  installed  on  the  front  passenger  seat . For a  listing  of the  child  re
straints  that  were  used to  certify  compliance

The PASSENGER  AIR  BAG OFF light in the  in
strument  panel tells  you  when  the  front  Ad
vanced  A irbag  on  the  passenger  side  has  bee n 
turned  off  by the  electronic  control  unit. 
Each t ime  you  turn  on  the  ignition,  the 
PAS 
SENGER  AIR  BAG OFF 
light  will  come  on  for  a 
few  seconds  and : 
- will stay  on  if the  front  passenger  seat  is  not 
occupied, 
- 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 oc
cupied  by an  adult  as  registered  by the 
weight-sensing  mat 
Q page  156,  Monitor
ing  the Advanced Airbag  System . 
The PASSENGER  AIR  BAG OFF light  comes on 
when  the  control  un it  detects  a total  weight 
on  the  front  passenger  seat  that  requires  the 
front  airbag  to  be  turned  off. 
Airbag system  147 
If  the total  weight  on  the  front  passenger 
seat  is  more  than  that  of a  typical  1 year-o ld 
c hild  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  a irbag  on  the  passenger side  has  not 
been  turned  off by the  electronic  con trol unit 
and  can  deploy  if the  contr ol unit senses  an 
impact  that  meets  the cond itions  stored  in its 
memory . 
For example,  the airbag  may  deploy  if: 
-a  small  ch ild  that  is  heav ie r  than  a  typical  1 
year-old  ch ild is  o n the  front  passenger  seat 
(regard less  of whether  the  child  is  in one  of 
the  child  safety  seats  listed 
Q page  168), 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  illum inate  and  stay  lit) even  if a 
small  adult  or  teenager,  or  a  passenger who is 
not  sitting  uprig ht  with  their  back  against  a 
non-reclined  backrest  w ith 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  thro ugh interaction  with  the 
airbag . "Low  risk" deployment  occ urs in  those 
crashes  that  take  place  at  lower  dece lerat ions 
as  defined  in the  electronic  control  unit 
Q page  156,  PASSENGER AIR  BAG OFF light . 
Always  remember,  a child  safety  seat  or  infant 
carr ier  installed  on  the  front  seat  may  be 
struck  and  knocked  out of  posit ion  by the  rap
idly  inflating  passenger's  airbag  in a frontal 
collision . The  airbag  could  greatly  reduce  the 
effectiveness  of the  child  restraint  and  even 
seriously  injure the  child  during  inflation.  •
