Advanced Airbag  System  components 
The front  passenger  seat  in your  vehicle  has  a 
l ot  of very  important  parts  of the  Advanced 
Ai rbag  System  in  it.  These  parts  incl ude  the 
capacitive  passenger  detection  system,  wir 
i n g,  brackets,  and  more . The  control  unit 
monitors  the  system  o n the  front  passenger 
seat  when  the  ign ition  is switched  on  and 
turns  the  airbag  indicator  light  on  when  a 
malfunct ion  in the  one  of  the  system  compo
nents  is detected  ¢ 
page 160. Because  the 
front  passenger  seat  contains  important  parts 
of the  Advanced  Airbag  System,  you  must 
t ake  care  to  p reven t  it  from  being  damaged. 
D amage  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  sensors  in the  front  o f the  veh icle  that 
measure  vehicle  acceleration/dece leration 
to  provide  information  to  the  Advanced  Air
bag  System  about  the  severity  of  the  crash . 
- An electronic  co ntrol  unit,  with  integrated 
crash  sensors  for  front  and  side  impacts . 
The  contro l unit  "decides"  whether  to  fire

Two seporate  indicators  monitor  the  function 
of  the Advanced Airbag  System:  the  airbag 
monitoring  indicator  light  and  the 
PASSEN 
GER AIR BAG OFF light. 
The Advanced Ai rbag System  (incl uding  the 
electronic  control  unit,  sensor circu its  and sys
tem  wir ing)  is mo nitored  continuously  to 
make sure that  it  is funct io ni ng  properly 
whenever  the  ignition  is on . Each time  you 
switch  on  the  ignition,  the  ai rbag mon itor ing 
i ndica to r li ght

- does not  come  on when  the  ignition  is 
sw itched  on, 
- does not  go out  a few  seconds after  you 
have sw itched  on the  ignit io n, or 
- comes on whil e dr iv ing . 
If  an airbag  system  malfunction  is detected, 
the  indicator  lig ht  w ill first  sta rt  flash ing to 
catch the  driver's  attent io n  and then  stay on 
continuously  to  serve as a co nstant  rem inder 
to  have the  system  inspected  immediately.

chlorate.  When  the  vehicle  or  parts  of  the 
restraint  system  including  airbag  modules 
and safety  belts  wit h pretens ioners are 
scrapped,  all  applicable  laws and  regula
tions  must  be observed. Your authorized 
Aud i dea ler  is familiar  wit h these  requ ire
ments  and we  recommend  that  you  have 
your  dea le r  perfo rm this  se rv ice for  you. 
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 Aud i, 
lowering  the  vehicle,  changing  the  stiffness  of 
the  suspension,  including  the  springs,  suspen
sion  st ruts,  shock absorbers  etc.  can change 
the  forces  that  are measured  by the  a irbag 
sensors and se nt  to  the  electron ic control 
un it.  Some suspension  changes can, for  exam
p le,  increase  the  force  levels meas ured 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  a irbag 
from  deploying  when  it  should. 
A WARNING 
Changing the  vehicle's  suspension  includ
ing  use of  unapproved  tire -rim  combina
tions  can change Advan ced A irbag  per
formance  and increase  the risk of  serio us 
personal  in jury in  a crash. 
- Never install  suspension  components 
that  do not  have the  same performance  character istics  as the  components  origi
nally  installed  on your  vehicle. 
- Never use tire-rim  combinatio ns that 
have not  been approved  by A udi. 
Knee  airbags 
Description  of  knee airbags 
Applies  to  vehicles: with  knee  airbags 
The knee  airbag  system  can provide  supple
mental  protection  to  properly  restrained 
front  seat  occupants. 
F ig . 1 65  Driver's  knee airbag 
The driver  knee airbag  is  in  the ins trumen t 
pane l underneath  t he steering  wheel 
¢ fig.  165, the  airbag  for  the  passenger  is at 
about  the  same height  in the  instrument  pan

T he knee airbag  offe rs additional  p rotection 
to  the  driver 's and passenger's  knees and up
per and  lower  th igh areas and supplements 
the  protection  provided  by the  safety  belts. 
If t he front  airbags  dep loy , the  knee ai rbags

is met 
¢ page  15 7, More important  things  to 
know  about  front  airbags. 
In  addition  to  their  norma l safety  function, 
safety  belts  help  keep the  dr iver or  front  pas
senger  in position  in a fronta l collision  so that 
the  a irbags can provide  supplemental  protec
t ion . 
The airbag  system  is not  a substit ute  for  your 
safety  belt.  Rather,  it  is part  of  the overa ll oc
cupant  restra int  system  in your  vehicle.  Al
ways remember  that  the  a irbag  system  can 
o nly help  to  protect  you  if you  are weari ng 
your  safety  belt  and wea ring  i t properly.  This 
is why you  should  always wear your  safety 
belt,  not just  beca use the  law  requi res you to

The side  airbag  system  basically con sists  of: 
- the  e lectronic  control  module  and  external 
s ide  impact  sensors 
- the  two  airbags  located  in the  sides  of the 
front  backrests  and  the  two  airbags*  located 
in the  rear  backrest 
- the  airbag  warning  light  in  the  instrument 
cluster. 
The  airbag  system  is  monito red  elect ron ica lly 
to  make  certain  that  it  is functioning  properly 
at  all times.  Each  time  you  switch  on  the  igni
tion,  the  airbag  system  indicator  light  will 
come  on  for  a few  seconds  (self  diagnostics) . 
T he  side  airbag  system  supplements  the  safe
ty  belts  and  can  help  to  reduce  the  risk of  in 
jury  to  the  driver's,  front  and  rear  passenger's  upper  torso  on  t he side  of  the  vehicle  that  is 
struck  in a  side  collision . The  airbag  deploys 
only  in  s ide  impac ts and  on ly when  the  veh icle 
acceleration  registered  by the  control  u nit  is 
hi gh  enough . If  this  rate  is below  the  refer
e nce va lue  progr ammed  i nto  the  con trol  un it, 
the  side  airbags  will  not  be  triggered,  even 
though  the  ca r may  be  badly  damaged  as  a  re
sult  of the  collision . It  is not  possible  to  de
f ine  an  a irbag  trigger ing  range  that  will  cover 
eve ry  possible  angle  of  impact,  since  the  cir
cumstances  will vary  considerably  between 
one  co llision  and  another . Important  facto rs

Aside  from  the ir no rmal  safety  function,  safe
ty  belts  wor k to  he lp keep  the  d river or  front 
passenger  in  posi tion  in the  event  of  a  side

protection. 
T he  airbag  system  is 
not a  substi tute  fo r your 
s af ety belt . Ra ther,  it  is  part  o f the  over all oc

ways  remember  that  the  side  airbag  system 
can  on ly help  to  protect  yo u  if you  are  wearing 
your  safety  be lt  and  wearing  it  proper ly. This 
is another  reason  why you  should  always  wear 
your  safety  be lts,  not  just  because  the  law  re
quires  you to  do  so c::;,

It  is  important  to  remember  that  wh ile  the 
suppleme nta l side  airbag  system  is  desig ned 
to  r educe  the  likelihood  of  ser ious  injuries, 
othe r injur ies,  for  exampl e, swelling,  bru is ing ,

Vehicle  damage,  repair  costs  o r even  the  lack 
of  ve hicle  damage  are  not  necessarily  a n indi 
cation  of over-sensitive  or failed  airbag  activa
tion.  In  some  coll is ions,  both  front  and  side 
a irbags  may  inflate.  Remember  too,  that  air
bags  will deploy  only  once  a nd  only  in  cer tain 
ki nds  of  col lisions  -you r safety  belts  a re a l
ways  t he re to  offe r protection  in those  acc i
dents  i n which  a irbags  are  not  supposed  to 
deploy  or  when  they  have  a lready  deployed . 
The side  airbag  system  will  not  deploy: 
-when  the  ignit io n  is switched  off 
- in  side  co llisions  whe n the  acceleration 
meas ured  by t he  sensor  is too  low 
- in front-end  collisions 
- in  rear -end  co llisions 
- in  rollove rs .

The  side  curtain  airbags  are  located on  both 
sides  of  th e  interior  above  the front  and  rear 
side  windows ~ 
fig.  169. They are ident ified 
by the  word  "AIRBAG" on  the windshield 
frame  and the  center  roof  pillar. 
The  side  curtain  airbag  system  supplements 
the  safety  belts  and  can  help  to  reduce  the  risk of  injury for  occupants'  heads  and uppe r 
torso  on the  side  of the  vehicle  that  is struck 
in  a  side  collision . The  side  curtain  airbag  in
flates  in side  impacts and  only  when  the  vehi
cle  acceleration  registered  by the  control  unit  is high  enough.  If this  rate  is  below  the  refer
ence  value  programmed  into the  control  unit, 
the  side  curtain  airbag  will  not  be  triggered, 
even  though  the  car  may  be  badly  damaged  as 
a  result  of the  collision.  It  is not  possible  to 
define  an  airbag triggering  range  that  will 
cover  every  possible  angle of impact,  since the 
circumstances  will  vary considerably  between 
one  collision  and  another.  Important factors 
include,  for  example,  the nature  (hard  or soft) 
of the  impacting  object,  the  angle  of  impact, 
vehicle  speed, etc.~ 
page 171,  How side  cur
tain  airbags  work. 
Aside  from  their  normal  safety  function,  safe
ty  belts  work  to  help  keep  the  driver  or front 
passenger  in  position  in the  event  of a  colli
sion  so  that the  side  curtain  airbags  can  pro
vide  protection. 
The airbag  system  is not  a  substitute  for  your 
safety  belt.  Rather, it  is  part  of  the  overall  oc
cupant  restraint  system  in your  vehicle.  Al
ways  remember  that the  airbag  system  can 
only  help  to  protect  you  if you  are  wearing 
your  safety  belt  and  wearing  it  properly.  This 
is another  reason why you  should  always  wear 
your  safety  belts,  not  just  because  the law  re
quires  you  to do  so 
Q page  138,  General 
notes. 
It is  important  to  remember  that  while  the 
side  curtain  airbag  system  is designed  to help 
reduce  the  likelihood  of serious  injuries, other 
injuries,  for  example,  swelling,  bruising,  fric 
tion  burns  and  minor  abrasions  can  also  be  as
sociated  with  these  airbags  upon  deployment.  Remember  too, these  airbags  will deploy  only  once  and  only  in  certain  kinds  of accidents 
-
your  safety  belts  are  always  there  to  offer  pro
tection. 
The  side curtain  airbag  system  basically 
consists of: 
- The electronic  control  module  and  external 
side  impact  sensors 
- The  side  curtain  airbags  above  the  front  and 
rear  side  windows 
- The  airbag  indicator  light  in the  instrument 
panel 
The  airbag  system  is monitored  electronically 
to  make  certain  it  is functioning  properly  at all 
times.  Each time  you  switch  on  the  ignition, 
the  airbag  system  indicator light  will come  on 
for  a few  seconds  (self  diagnostics). 
The  side curtain  airbag  is not  activated: 
- if  the  ignition  is switched  off, 
- in side  collisions  when  the  acceleration 
measured  by the  sensor  is  too low, 
- in  rear-end  collisions. 
_&. WARNING 
- Safety  belts  and  the  airbag  system  will 
only  provide  protection  when  occupants 
are  in the  proper  seating  position 
¢page  53,  General recommendations. 
- If the  airbag  indicator  light Q page  19 
comes  when  the  vehicle  is  being used, 
have  the  system  inspected  immediately 
by your  authorized  Audi  dealer. It is pos
sible  that  the  airbag  will  inflate when  it 
is not  supposed  to,  or  will not  inflate 
when  it  should.

Audi  pre  sense 
Preventative  passenger 
protection 
A pp lies  to  veh icles: with  Audi  pre se nse 
Audi  pre sense can initiate  steps  to  help  pro
tect  vehicle  occupants  in certain  situations. 
The  functions  described  depend  on  equ ipment 
installed  in your  vehicle: 
Audi  pre  sense basic* 
The following  functions  can be triggered in 
certain  driving  situations: 
- Tightening  of  the safety  belts  (for  example, 
during  heavy braking) : the  front  safety  belts 
have  reversible  belt  pretensioners.  If  a colli
sion does not  occur, the  safety  belts  loosen 
slightly  and are ready to  be tightened  again. 
- Closing the  windows  and the  sunroof*:  the 
windows  and the  sunroof*  close  leaving a 
small  open  gap. 
Audi  pre sense basic  functions can be trig
gered at speeds above 20 mph (30 km/h). 
Vehicles with  Aud i drive  select*:  the  deploy
ment  time  is adapted  in 
Dynamic mode. 
Audi  pre  sense front (vehicles  with 
adaptive  cruise control*) 
Audi  pre sense front  includes  the  functions  in 
Audi  pre sense basic. In  addition,  within  the 
limits  of  the  system,  the  likelihood of  a colli 
sion with  the  vehicle  immediately ahead is al
so calculated . If  the  system  senses an  immi
nent  collision  the  following functions  can be 
tr iggered : 
- Braking  guard 
c::> page 92 
- Tightening  the  safety  be lts 
- Closing  the  windows  and  the sunroof*  (leav -
ing  a small  open  gap) 
Audi  pre  sense rear (vehicles  with  Audi 
side  assist*) 
Audi  pre sense rear  includes the  functions  in 
Audi  pre sense basic. In  addition,  the  likeli
hood  of  a rear-end  collision  with  the  vehicle 
coming  from  behind  is also calcu lated. 
If the  risk 
of  a co llision  is  detected,  the  following 
functions  can be triggered: 
- Tig htening  the  safety  belts 
- Closing  the windows  and the  sunroof*  (leav-
ing  a  small  open  gap) 
Audi  pre  sense plus* 
Audi  pre sense plus  includes  the  functions  in 
Audi  pre sense front  and Audi  pre sense rear. 
Error  message 
Audi pre  sense: not available 
Preventative  passenger protection  is not  avail
able.  See your  authorized  Audi  dealer immedi
ately  to  have the  malfunction  corrected. 
_& WARNING 
-= 
Audi  pre sense cannot  overcome  the  laws 
of  physics. It  cannot  prevent a collision.  Do 
not  let  the  increased  safety provided 
tempt  you to  take  risks. This will  increase 
the  r isk of  a collis ion  and serious  personal 
in juries . 
- The sensors cannot  always detect  all  ob
jects.  This increases  the  risk of  a colli
s10n. 
-Aud i pre sense does not  detect  people  or 
an im als  or objects  that  are  crossing the 
veh icle's  path 
c::> page 86. 
-The radar  sensor's vis ion can be reduced 
by heavy rain,  ice, snow,  heavy road sp ray 
and  reflections  from  guard  rails,  tunnel 
entrances,  etc.  These and similar  condi
tions  can prevent  vehicles from  being  ac 
curately  detected  and  in some  cases they 
may  not  be detected  at  all. 
(D Note 
The sensors can be displaced  by  impacts  or 
damage  to  the  bumper,  wheel  housing  and 
underbody.  This can affect  the  function  of 
the  Audi  pre sense system.  Have your  au
thorized  Audi  dealer  check to  make sure 
that  the  system  is working  properly.

Winter t ire s 
When  driving  in the  w inter,  your  vehicle  w ith 
all-wheel  drive  has  an  advantage,  even  with 
regular  tires.  In  winter  road  conditions  it  may 
be  advisable  to  mount  winter  tires  (or  all-sea
son  tires)  for  improved  driveability  and  brak ing:  these  tires  must  be  mounted  on 
a ll  fo ur 
wheels . 
See  also c:> page  267,  Winter  tires. 
Tire  chain s 
Where  tire  cha ins  are  mandatory  on  certain 
roads,  th is  normally  a lso  applies  to  vehicles 
with  all-wheel  drive 
c> page  268,  Snow 
chains. 
Re placing  wh eels/ tire s 
Vehicles  w ith  all-wheel  drive  must  a lways 
have  tires  of  the  same  size.  Also  avoid  tires 
with  different  tread  depths.  For  details  see 
page 
c:> page  260,  New tires  and  replacing 
tires and  wheels . 
Off-Road dri ving ? 
Your Audi  does  not  have  enough  ground  clear
ance  to  be  used  as  an  off-road  vehicle.  It  is 
therefore  best  to  avoid  rough  tracks  and  un
even  terrain  as  much  as  possible.  Also  refer  to 
c:>page204. 
A WARNING 
Always  adjust  your  driving  to  road  and  traf
fic  condit ions . Do not  let  the  extra  safety 
afforded  by all-wheel  dr ive tempt  you  into 
taking  extra  risks. 
- Although  the  all-wheel  dr ive  is very  ef
fec tive, a lways  remember  that  braking 
capacity  is limited  by t ire  traction.  Yo u 
should  therefore  not  dr ive at  excessive 
speeds  on  icy or  slippery  road  surfaces. 
- On wet  road  surfaces,  be  careful  not  to 
drive  too  fast  because  the  front  wheels  cou ld  begin  to  slide  on  top  of  the  water 
(aquaplaning).  If  this  sho uld  occur,  you 
will  have  no warning  from  a  sudden  in
crease  in engine  speed  as  with  a front
wheel  drive  vehicle.  A lways  drive  at 
speeds  wh ich  are  suited  to  the  road  con
ditions  -risk  of  c rash.

Energy  management 
Starting  ability  is optimized 
Energy management  controls  the  distribution 
of  electrical  energy  and  thus  optimizes  the 
availability  of electrical  energy  for starting  the  engine. 
If  a vehicle  with  a conventional  energy  system 
is  not  d riven for  a  long  per iod  of  t ime,  the  bat
tery  is discharged  by idling  current  consumers  (e .g.  immobilize r).  In  certain  circumstances  it 
can  resu lt  in the re  be ing  insuffic ient  energy 
available  to  start  the  engine. 
Intelligent  energy  management  in your  vehi
cl e  ha ndles  the  distribution  of  e lectr ica l ene r
gy.  Start ing  ability  is markedly  improved  and 
the  life  of  the  battery  is extended . 
Bas ica lly, energy  management  consists  of 
ba tter y dia gno sis,  id lin g curr ent manage
ment 
and dynamic ener gy manag ement. 
Battery  di agnos is 
Battery  diagnosis  continuously  determ ines 
the  state  of  the  batte ry . Sensors  determine 
battery  voltage,  battery  current  and  battery 
tempe rature.  This  de termines  the  curren t 
state  of  cha rge  and  the  power  of  the  battery . 
Idling  current  management 
Idling  current  management  reduces  energy 
consumption  while  the  vehicle  is standing . 
With  the  ign ition  switched  off,  it  controls  the 
energy  supply  to  the  various  electrica l compo 
nents.  Da ta  fr om  ba ttery  d iagnos is  is cons id 
ered. 
Depend ing  on  the  batte ry's  state  of  cha rge, 
individ ual  cons ume rs a re g radually  turned  off 
to  prevent  excessive  discharge  o f the  battery 
and  th us  maintain  star ting  capability. 
Dynamic  energy  management 
While  the  vehicle  is being  dr iven,  dynamic  e n
ergy  ma nagement  distr ibutes  the  energy  gen
erated  a ccord ing  to  the  needs  of  the  individ u-
al  components . It  regulates  consumpt ion,  so 
that  more  e lectrical  energy  is  not  being  used  .,.

A WARNING 
-Only wash  the  vehicle  when  the  ignition 
is off  and  follow  the  instructions  from 
the  car  wash  operator  to  reduce  the  risk  of  accidents . 
- To reduce  the  r isk  of  cuts,  protect  your
self  from  sharp  metal  components  when 
wash ing  the  underbody  or  the  inside  of 
t he  wheel  housings. 
- After  washing  the  vehicle,  the  braking  ef
fec t may  be  delayed  due  to  mo isture  on 
the  brake  rotors  or  ice  in the  winter.  The 
brakes  must  be  dried  first  with  a few 
careful  brake  applications. 
Q) Note 
- If  you  wash  t he  vehicle  in  an  automatic 
car  wash,  yo u must  retrac t the  rear  spoil
er  if necessary,  and  fo ld  the  exter ior  mir
rors  in to  reduce  the  risk  of  damage. 
Power  folding  exterior mirrors*  must  on
l y be  folded  in  and out  using  the  power 
fo ld ing  funct ion. 
- To prevent  paint  damage,  do  not  wash 
the  veh icle  in direct  sunlight.  -
To  reduce  the risk  of  damage  to  the  sur
face,  do  not  use  insect removing  spong
es,  kitchen  sponges or  similar  items. 
- Matte  finish  painted  vehicle  compo
nents: 
- To reduce  the  risk  of  damage  to  the  surface,  do  not  use  polishing  agents  or hard  wax. 
- Never  use  car  wash  cycles  that  apply  protective  wax. 
It can  destroy  the 
matte  fi nish  effect. 
- Do not  place  any  stickers or  magnet ic 
signs  on  vehicle  parts  painted  w ith
