Before  you  check  anything  in the  engine  compartÂ
ment, 
always  re ad  a nd  hee d all  W ARNING S 
¢ A in  Working  in  the  engine  compartment  on 
page  220. 
.,  Read  the  brake  fluid  level  from  the  brake  fluid 
reservoir 
<=> fig . 202,  ¢page  222. The  brake  flu Â
id  level  must  be  between  the  "MIN" and "MAX" 
mark ings. 
The  location  of  the  brake  fluid  reservoir  can  be  seen  in the  engine  compartment  illustration 
¢ page  222. 
The  fluid  level  may  drop slightly after  some  time 
due  to  the  automatic  adjustment  of  the  brake 
pads . This  is not  cause  for  alarm . 
If  the  brake  fluid  level  falls 
considerably below 
the  ' 'MIN" mark,  the  brake  warning/indicator

Changing  brake  fluid 
Have the  brake  fluid  changed  by an experienced 
technician . 
Brake  fluid  absorbs  moisture  from  the  air. If the 
water  content  in the  brake  fluid  is too  high,  cor rosion  in the  brake  system  may  result  after  apeÂ
riod  of  time . The  boiling  po int  of the  brake  fluid 
will a lso  decrease  considerably  and  decrease 
braking  performance. 
Therefore , the  brake  fluid  must  be  changed 
eve ry 
two  y ears . Always  use  new  brake  fluid  which  conÂ
forms  to  Feder-al Motor  Vehicle  Standard  "FMVSS  116  DO T 4". 
The  brake  fluid  reservoir  can  be  difficult  to  reach , 
therefore,  we  recommend  that  you  have  the  brake  fluid  changed  by your  author ized 
Audi 
d ea ler . Your  dealer  has  the  correct  tools,  the 
right  brake  fluid  and  the  know -how  to  do  this  for 
you. 
A WARNING 
- Brake fluid  is  po isonous.  It  must  be  stored 
only  in the  closed  original  container  out  of 
the  reach  of children! 
- Brake fai lure  can  result  from  o ld  or  inapproÂ
priate  brake  fluid . Observe  these  precauÂ
tions: 
- Use only  brake  fluid  that  meets  SAE speci ficat ion 
J 1703  and  conforms  to  Federal 
Motor  Ve hicle  Standard  116.  Always check 
with  your  authorized  Audi  dealer  to  make 
sure  you  are  using  the  correct  brake  f luid . 
The  correct  type  of  brake  f luid  is also  indiÂ
cated  on  the  brake  fluid  reservoir. 
- The  brake  fluid  must  be  new . Heavy use  of 
the  brakes  can  cause  a  vapor  lock  if the 
brake  fluid  is  left  in the  system  too  long . 
This  can  seriously  affect  the  efficiency  of 
the  brakes  as  well  as your  safety.  This 
could  result  in an  accident.

@ For the  sake  of  the  environment 
Because  of  the  problem  of  proper  disposal of 
brake  fluid  as  we ll as  the  special  toots  reÂ
quired  and  the  necessary  expertise,  we  recÂ
ommend  that  you  have  the  brake fluid

Battery 
General  information 
Under normal operating  conditions,  the  battery 
in your  Audi  does  not  need  any  maint enance. 
With 
high outside  temperatures  or  long  daily 
drives  we  recommend  tha t you  have  the  electroÂ
lyte  level  checked  by a  service  facility.  The  elecÂ
trolyte  level should  also  be  checked  each  time 
the  battery  is charged  ¢ 
page  233. 
Have the  battery  checked  when  you  take  your  veÂ
hicle  in for  serv ice.  You are  well  advised  to  reÂ
place  a  battery  that  is older  than  5 years . 
With  certain  types  of airbag  deployment,  the  batte ry  is  disconnected  from  the  vehicle  electriÂ
cal  system  for  safety  reasons¢ 
& in Repair,  care 
and  disposal  of  the  airbags  on page  159 . 
Disconnecting  the  battery  terminals 
Some  vehicle  functions  (power window  regu laÂ
tors,  for example)  are  lost  if the  battery  te rmi Â
nals  are  disconnected.  These  functions  have  to  be 
relearned  after  the  battery  terminals  are  conÂ
nected  again.  To prevent  th is,  the  battery  should 
only  be  disconnected  from the vehicle  e lectr ica l 
system  when  abso lutely  necessary  for repairs. 
Vehicles  not  driven  for  long  periods 
If  you  do  not  drive  your  vehicle  over  a  period  of 
several  days  or weeks,  electrical  components  are 
gradually  cut  back  or  sw itched  off.  This  reduces 
ene rgy consumption  and  ma inta ins  starting  caÂ
pability  over  a  longer  period ¢ 
page  195. Some 
of  the  convenience  functions may  not operate, 
such  as  the  interior  lights or the  power  seat adÂ
justment.  The convenience  funct ions  will  be 
ava ilable  again  when  you  switch  on  the  ignition 
and  start  the  engine. 
Checking  and Filling 
Winter  operation 
During  the  winter months,  battery capacity  tends 
to  decrease  as  temperatures  drop . This  is beÂ
cause  more  power  is also  consumed  while  startÂ
ing,  and  the  headlights,  rear  window  defogger, 
etc.,  are  used  more  often. 
Avo id  unnecessary  power  consumption,  particuÂ
larly  in  city traffic  or  when traveling  only  short 
distances . Let  your  authorized  Audi  dealer  check 
the  capacity  of the  vehicle  battery  before  winter 
sets  in  ¢ 
page  233. A well  charged  battery will 
not  only  prevent starting  problems  when  the 
weather  is  cold,  but  will also  last  longer . 
(D Tips 
If  your  vehicle  is  left  standing  for  several 
weeks  at extremely  low temperatures,  the  veÂ
hicle  battery  should  be  removed and  stored 
where  it  w ill not  freeze . This  will  prevent  it 
from  be ing damaged  and  having  to  be reÂ
placed. 
Working  on  the  battery 
Be  especially  careful  when  working  on  or near 
the  battery. 
The  battery  is  located  in the luggage  compartÂ
ment  under  the  floor . Before  you  check  anything 
in the  luggage  compartment, 
read and heed all

_& WARNING 
Temperature  grades  apply  to  tires  that  are 
properly  inflated  and  not  over  or  underinf lat Â
ed. 
Tire  pressure  monitoring  system 
U) General  notes 
Applies  to:  vehicles with  tire  pressure  monito ring  system 
Each  tire, including  the spare  (if  provided), 
should  be  checked  monthly  when  cold  and  inflatÂ
ed  to  the  inflation  pressure  recommended  by the 
vehicle  manufacturer  on  the  vehicle placard  or 
tire  inflat ion  pressure  label.  (If  your vehicle  has 
tires  of  a different  size  than  the  size  indicated  on 
the  vehicle  placard  or tire  inflation  pressure  laÂ
bel,  you  should  determine  the  proper  tire  inflaÂ
tion  pressure  fo r those  tir es) . 
As an  added  safety  feature,  your  vehicle  has  been 
equipped  with  a t ire  pressure  monitoring  system 
(TPMS) that  illuminates  a  low tire  pressure  tellÂ
tale  when  one  or  more  of your  tires is significantÂ
ly  under-inflated . Accord ingly,  when  the  low tire 
p ressure  telltale  illuminates,  you  should  stop  and 
check  your  tires  as  soon  as  possible,  and  inflate 
them  to  the  proper  pressure.  Driving on  a signifiÂ
cantly  under-inflated  tire  causes the  tire  to  overÂ
heat  and  can  lead to  tire failure.  Under-inflation 
also  reduces  fuel  efficiency  and  tire tread  life, 
and  may  affect  the  vehicle's  handling  and  stopÂ
ping  ability. 
Please  note  that  the TPMS  is  not  a  substitute  for 
proper  tire maintenance,  and  it  is the  driver's  reÂ
sponsib ility to  maintain  correct  tire  pressure, 
even  if under-inflation  has  not  reached  the  level 
to  trigger  illumination  of the  TPMS low tire  presÂ
sure  telltale. 
Your vehicle  has  also  been  equipped  with  a  TPMS 
malfunct ion  indicator  to  indicate when  the  sysÂ
tem  is  not  operating  properly.  The  TPMS malÂ
function  indicator  is comb ined  w ith  the  low tire 
pressure  telltale. When  the  system  detects  a 
malfunction,  the  telltale  will flash  for  approxiÂ
mately  one  minute  and  then  remain  cont inuous ly 
illuminated.  This sequence  will continue  upon 
254 
subsequent  vehicle  start-ups  as  long as  the  malÂ
function  exists. 
When  the malfunction  indicator  is  illum inated, 
the  system  may  not  be  able to  detect  or s ignal 
low  tire  pressure  as  intended . TPMS malfunctions 
may  occur  for  a variety  of  reasons,  including  the 
i nstallation  of  replacement  or  alternate  tires  or 
wheels  on  the vehicle  that  prevent  the TPMS 
from  functioning  properly.  Always  check  the 
TPMS  malfunction  telltale  after  replacing  one  or 
more  tires  or wheels  on your  vehicle  to  ensure 
that  the  replacement  or  alternate  tires  and 
whee ls  allow  the  TPMS to  continue  to  function 
properly. 
If  the  Tire  Pressure Monitoring  System 
indicator  appears 
Applies  to:  vehicles with  tire  pressure  monitoring  system 
The tire pressure  indicator in the  instrument 
cluster  informs you  if the  tire pressure  is too  low 
or  if there  is a system  malfunction. 
Fig . 209 Instrument  cl uste r:  indicator  light  with  me ssage 
Using  the  ABS sensors,  the  tire  pressure  monitorÂ

Fuses  a nd  bul bs 
Bulbs 
Replacing  light  bulbs 
For your  safety,  we recommend  that  you  have 
your  authorized  Audi dealer  replace  burned  out 
bulbs  for you. 
It  is becoming  increasingly  more  and  more  diffiÂ
cult  to  replace  vehicle  light  bulbs  since  in  many 
cases,  other  parts  of  the  car  must  first  be  reÂ
moved  before  you  are  able  to  get  to  the  bu lb . 
This applies  espec ially  to  the  light  bulbs  in the 
front  of  your  car  wh ich you  can  only  reach 
through  the  engine  compartment . 
Sheet  metal  and  bulb  holders  can  have  sharp 
edges  that  can  cause  ser ious  cuts,  and  parts 
m ust  be  correctly  taken  apa rt  and  then  p roperly 
put  back  together  to  help  prevent  breakage  of 
parts  and  long  term  damage  from  water  that  can 
enter  housings  that  have  not  been  properly  reÂ
sealed. 
For your  safety,  we  recommend  that  you  have 
your  authorized  Audi  dealer  replace  any  bu lbs  for 
you,  since  your  dealer  has  the  proper  tools,  the  correct  bulbs  and  the  expertise. 
G as  di sc harg e  l am ps  (Xe non li ghts): 
Due to  the  high  electrical  voltage,  have  the  bulbs 
replaced  by a  qua lified  technic ian . Headlights 
with  Xenon  light  can  be  identified  by the  high 
voltage  sticker. 
LED headlights*  require  no  maintenance.  Please 
contact  your  authorized  Aud i dealer  if a  bulb 
needs  to  be  replaced. 
A WARNING 
Contact  w ith  high-voltage  components  of  the 
electrical  system  and  improper  rep lacement 
of  gas  discharge  (Xenon)  headlight  bulbs  can 
cause  serious  personal  injury  and  death. 
- Xenon  bulbs  are  pressurized  and  can  exÂ
plode  when  being  changed. 
- Changing  Xenon  lamps  requires  the  special  training,  instructions  and  equipment. 
- Only an  a uthorized  Audi  dea ler  or  other 
qualified  workshop  should  change  the  bulbs 
in gas  discharge  lamps .

A WARNING 
-
There  are  parts  with  sharp  edges  on  the  open- ings  and  on  the  bulb  holders  that  can  cause 
serious  cuts. 
- If you  are  uncertain  about  what  to  do,  have 
the  work  performed  by an  authorized  Audi 
dealer  or  other  qualified  workshop.  Ser ious 
pe rsonal  injury  may  resu lt  from  improperly 
pe rformed  wor k. 
@ Tips 
- If you  must  replace  the  light  bulbs  yourself, 
always  remember  that  the  eng ine  compartÂ
ment  of  any  vehicle  is a  hazardous  area  to 
work  in.  Always  read  and  heed  all WARNÂ INGS ~ 
page  220. 
-It is  best  to  ask  your  authorized  Audi  dealer 
whenever  you  need  to  change  a  bulb.
