A WARNING 
- Always  look  for traffic  and check the  area 
around  your  vehicle  by looking  at  it directly 
as well.  The parking  system  cannot  replace 
the  driver 's attention.  The driver  is always 
responsible  when  entering  or  leaving a park
ing space and  during  similar  maneuvers. 
- Please note  that  some  surfaces,  such as 
clothing,  are not  detected  by the  system. 
-
- Sensors and cameras  have blind  spots  in 
which  people  and objects  cannot  be detect ed . Be especially  cautious  of  small  children 
and animals . 
- Always  keep your  eyes on  the  vehicle's  sur
roundings,  using  the  rearview  mirror  as 
well . 
- The sensors can be displaced  by  impacts or 
damage  to  the  radiator  grille,  bumper, 
wheel  housing  and the  underbody . The park

Airbag system 
A 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  armrest,  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  be cause  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 . 
A WARNING 
Objects  between  you  and  the  airbag  will  in
crease  the  risk  of injury  in a  crash  by interfer 
ing  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  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  dur
ing  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  cupholders,  telephone 
brackets,  large, heavy  or  bulky  objects)  on 
the  doors,  over  or  near  the  area  marked 
"AIRBAG" on  the  steering  wheel,  instru
ment  panel,  seat  backrests  or  between 
those  areas  and  yourself . These  objects 
could  cause  injury in  a crash,  especially 
when  the  airbags  inflate . 
- Never  recline  the  front  passenger's  seat  to 
transport  objects.  Items  can  also  move  into 
264 
the  area  of the  side  airbag  or the  front  air
bag  during  braking  or  in a  sudden  maneu
ver.  Objects  near  the  airbags  can  become  projectiles  and  cause  injury, particularly 
when  the  seat  is  reclined . 
- Never  place  or transport  objects  on  the 
front  passenger  seat.  Objects  on  the  front 
passenger  seat  could  cause  the  capacitive 
sensor  in  the seat  to  signal  to  airbag  system 
that  the  seat  is occupied  by a  person  when  it 
in fact  is not,  or that  the  person  on  the seat 
is heavier  than  he  or  she  actually  is.  The 
change  in electric  capacitance  because  of 
such  objects  can  cause  the  passenger  front 
airbag  to  be  turned  on  when  it should  be 
off,  or  can  cause  the  airbag  to  work  in a  way 
that  is different  from  the  way  it would  have 
worked  without  objects  on  the  seat . 
- Always  make  sure  that  there  is  nothing  on 
the  front  passenger  seat  that  will cause  the 
capacitive  passenger  detection  system  in 
the  seat  to  signal  to  the  Airbag  System  that  the  seat  is occupied  by a  person  when  it  is 
not , or  to  signal  that  it  is occupied  by some 
one  who  is  heavier  than  the person  actually 
sitting  on  the  seat.  The  presence of  an  ob
ject  could  cause  the  passenger  front  airbag 
to  be  turned  on  when  it  should  be  off,  or 
could  cause  the  airbag  to  work  in a way  that is different  from  the  way  it  would  have 
worked  without  the  object  on  the  seat . 
A WARNING 
The  fine  dust  created  when  airbags  deploy  can 
cause  breathing  problems  for  people  with  a 
history  of  asthma  or  other  breathing  condi
tions . 
- To reduce  the  risk  of  breathing  problems, 
those  with  asthma  or  other  respiratory con
ditions  should  get  fresh  air  right  away  by 
getting  out  of the  vehicle  or  opening  win
dows  or  doors. 
- If you  are in a  collision  in which airbags de
ploy , wash  your  hands  and  face  with  mild 
soap  and  water  before  eating. 
- Be careful  not  to  get  the dust  into  your  eyes, 
or  into  any  cuts  or  scratches.  ..,_

Repair , care and  disposal  of the  airbags 
Parts  of  the  a irbag  system  are  installed  at  many 
different  places  on your  Audi.  Installing,  remov ing,  servic ing  or  repa iring  a  part  in  an  area  of  the 
ve hicle  can  damage  a  part  of  an  airbag  system 
and  prevent  that  system  from  working  properly 
i n  a  collision . 
There  are  some  important  things  you  have  to 
know  to  make  sure  that  the  effectiveness  of  the 
system  w ill not  be  impaired  and  that  discarded 
components  do  not  cause  injury  or  pollute  the 
env ironment. 
A WARNING 
Improper  care,  serv icing  and  repai r proce
dures  can  increase  the  r is k  of  personal  injury 
and  death  by preventing  an  airbag  from  de
ploying  when  needed  or  dep loying  an  airbag 
unexpectedly: 
-
- Never  cover,  obstruct,  or  change  the  stee r
ing  wheel  horn  pad  or  airbag  cover  or  the  in
strument  pane l or  modify  them  in any  way. 
268 
- Never  attach  any  objects  s uch as  c upholders 
or  telephone  mountings  to  the  surfaces  cov
ering  the  a irbag  un its. 
- For cleaning  the  horn  pad  or  instrument 
panel,  use  only  a soft,  dry  cloth  or  one  mois
tened  w ith  plain  water.  Solvents  or  cleaners 
could  damage  the  airbag  cover  or  change 
the  st iffness  or  strength  of  the  material  so 
that  the  airbag  canno t deploy  and  p rotect 
properly. 
- Never  repair,  adjust , or  change  any  parts  of 
the  airbag  system. 
- All work  on  the  steering  wheel,  inst rument 
panel,  front  seats  or  e lectr ica l system  ( in
cluding  the  installation  of  a udio  eq uipment, 
cellular  telephones  and  C B radios,  etc.) 
m ust  be  perfo rmed  by a  qualified  techn ician 
who  has  the  training  and  specia l equipment 
necessary. 
- For any  work  on  the  airbag  system,  we  strong ly recommend  that  you  see  your  au
thorized  A udi  dealer  or  qualified  workshop. 
- Never  modify  the  front  b umper  or  parts  of 
the  vehicle  body. 
- Always  make  sure  that  the  side  a irbag  can 
inflate  w ithout  interference: 
- Never  install  seat  covers  or  replacement 
upholstery  over  the  front  seatbacks  that 
have  not  been  specifically  approved  by 
A udi. 
- Never  use  additional  seat  c ushions  that 
cover  the  areas  where  the  side  airbags  in
flate. 
- Damage  to  the  orig inal  seat  cove rs or  to 
the  seam  in the  area  of  the  s ide  airbag 
module  mus t always  be  repaired  immedi
ate ly by an  autho riz ed  Au di dealer. 
- The  a irbag  system  can  deploy  on ly once.  Af
ter  an airbag  h as  been  deployed,  i t m ust  be 
repla ced  with  new  replacement  parts  de
signed  and  approved  espec ia lly for  your 
Audi  model  version . Replacement  of  com
plete  airbag  systems  or  airbag  components 
must  be  perfo rmed  by qua lified  workshops 
only.  Make  su re that  any  airbag  service  ac

-The  tire  must  flex  more  if the tire  pressure  is too  low  or  if 
the  vehicle  speed  or  load  are 
too  high . This  heats  the  tire  up 
too  much.  This  increases  the 
risk  of  an  accident  because  it 
can  cause  the  tire  to  burst  and 
result  in loss  of vehicle  con
trol.

(i} For the  sake of the  environment 
-Tire  pressure  that  is too  low 
increases  fuel  consumption. 
-Fuel  consumption  may  also  in
crease  when  driving  with  the

A WARNING 
-If the  tire  pressure  indicator appears  in the 
display,  reduce your  speed  immediately  and 
avoid  any  hard  steering  or  braking  maneu
vers. Stop  as  soon  as  possible  and  check  the 
tires  and  their  pressure . 
- The  driver  is  responsible  for  maintaining  the 
correct  tire  pressure.  You must  check  the 
tire  pressure  regularly. 
- Under  certain  conditions  (such  as  a sporty 
driving  style,  winter  conditions  or  unpaved 
roads),  the  tire  pressure  monitoring  system 
indicator  may  be  delayed. 
@ Tips 
- The  tire  pressure  monitoring  system  can  al
so  stop  working  when  there  is an  ESC  mal
function. 
- Using  snow  chains  may  result  in  a system 
malfunction. 
- The  Tire  Pressure  Monitoring  System  in your 
Audi was  calibrated  with  "Audi  Original 
Tires "~ 
page  324. We  recommend  that  you 
use  these  tires. 
Storing  tire  pressures 
If  the  tire pressure  changes  or a  tire is replaced, 
it must  be confirmed  in the  Infotainment  sys
tem  . 
.. Before  storing  the  tire  pressures,  make  sure  the 
tire  pressures  of  all  four  tires  meet  the  speci
fied  values  and are  adapted  to  the  load 
~page  327 . 
.. Switch  on  the  ignition  . 
..  Select  in the  Infotainment  system:
