The  fl uid  level  may  drop slightly after  some  time 
due  to  the  automatic  adjustment  of  the  brake 
pads . This  is not  cause  for  alarm.

light  (U .S. mode ls: 
1111 , Canadian  models:.) 
will  come  on¢ 
page  18 and ¢ page  28 . Do not 
continue  to  operate  the  vehicle.  The  complete  brake  system  should  be  thoroughly  checked  by an 
author ized  Audi  dealer  or  qualified  workshop  and 
the  cause  corrected . If  the  brake  fluid  level  is  too 
low,  the  brake  warning/ind icator  light  will  illumi
nate.  Contact  an  authorized  Audi dealer 
immedi 
a te ly. 
Changing  brake  fluid 
Have the  brake  fluid  changed  by an experienced  technician. 
Brake  fluid  absorbs  mo isture  from  the  air.  If  the 
water  conte nt  in the  brake  fluid  is too  h igh,  cor
ros ion  in  the  brake  system  may  resu lt  after  ape
riod  of  time.  The  boiling  poi nt  of  the  brake  flu id 
will  also  dec rease  cons iderably  and  decrease 
braking  pe rformance. 
Therefore,  the  b rake  fluid  must  be  changed 
e ve ry 
two year s. 
Always  use  new  b rake  fluid  wh ich con
forms  to  Fede ral  Motor  Veh icle  St andard  "FMVSS 
116  DOT  4". 
The  brake  fluid  reservoir  can  be  diff icult  to  reach, 
therefore,  we  re commend  that  yo u have  the 
b rake  fl uid changed  by yo ur autho rized 
Audi 
deal er. 
Your dealer  has  the  cor rect  too ls,  the 
right  brake  fluid  and  the  know -how  to  do  this  for 
you. 
A WARNING 
- Brake  fluid  is  poisonous.  It  must  be  stored 
only  in the  closed  original  container  out  of 
the  reach  of  chi ldren! 
- B rake  failure  can  resu lt  from  old  or  inappro
pr iate  brake  flu id.  Observe  these  precau
t io ns: 
Ch eck ing  and  Filling 
-Use  only  brake  fluid  that  meets  SAE speci
ficat ion 
J 1703  and  conforms  to  Federal 
Motor  Vehicle  Standard  116.  Always  check 
with  your  authorized  Aud i dealer  to  make 
sure  you  are  us ing  the  correct  brake  fluid . 
The  co rrect  type  of  brake  flu id  is also  i ndi
cated  on  the  b rake  fluid  reservoir. 
- The  brake  flu id  must  be  new.  Heavy  use  of 
the  b rakes  can  cause  a vapo r lock  if the 
bra ke fluid  is  left  in the  system  too  long. 
T his  can  se riously  affe ct  the  efficiency  of 
t h e  b rakes  as  we ll as  you r safety . This 
could  resu lt  in an  accident. 
(D Note 
B rake  flu  id  will  damage  the  paint  of  your  ve h i

@) For the  sake of  the  environment 
Because  of  the  p roblem  of  proper  d isposa l of 
brake  fluid  as  well  as  the  spec ial  too ls  re
q uire d and  the  necessary  expertise,  we  rec
ommend  that  yo u have  the  bra ke  fluid 
c hanged  by yo ur authorize d Au di dealer. 
Battery 
General  information 
Under normal ope rat ing  condit ions,  the  batte ry 
in you r A udi does  not  need  any  mainte nance. 
Wi th 
high o utside  temperatures  or  long  daily 
drives  we  recommend  that  yo u  have  the  elec tro 
lyte  level  checked  by an  authorized  A udi  dealer  or 
qualified  workshop . The  electro lyte  level  should 
also  be  checked  each  time  the  battery  is charged 
~ page  231. 
Have  the  batte ry checked  when  you  take  your  ve
hicle  in for  service.  You are  we ll advised  to  re
place  a  battery  that  is older  than  S years. 
Wi th certain  types  of  airbag  deployment,  the 
battery  is d isconnected  from  the  veh icle  electri 
ca l system  for  safety  reasons¢.&.

Checking  and  Filling 
Disconnecting  the  battery  terminals 
Some  vehicle functions (power  window  regula
tors,  for  example)  are  lost  if the  battery  termi 
na ls  are  disconnected.  These functions  have  to  be 
relearned  after  the  battery terminals  are  con
nected  again.  To  prevent  this,  the battery  should 
only  be  disconnected  from  the  vehicle  e lectrical 
system  when  absolutely  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 
energy  consumption  and  ma intains  starting  ca
pab ility  over  a  longer  period 
c::> page  195 . 
Take  into  consideration  that  when  you  unlock 
your  veh icle,  some  convenience  functions,  such 
as  the  interior  lights  or  the  power  seat  adjust
ment,  may  not be  available.  The  convenience 
functions  will  be available  again  when  you  turn 
on  the  ignition  and  start  the engine. 
Winter  operation 
During the  winter  months,  battery  capacity tends 
to  decrease  as  temperatures  drop.  This  is  be
cause  more  power  is also  consumed  while  start
ing,  and  the  head lights,  rear  window  defogger, 
etc.,  are  used  more  often. 
Avoid unnecessary  power consumption,  particu
larly  in  city  traffic  or  when  traveling  only  short 
d istances . Let your  authorized  Audi  dealer  check 
the  capacity  of the  vehicle  battery  befo re winter 
sets  inc::> 
page  231. A well  cha rged  battery  w ill 
not  only preven t starting  problems  when the 
weather  is  cold, but  will  also  last  longer. 
Working  on  the  battery 
Be  especially  careful when  working  on  or near 
the  battery.

-Please  note  that  summer  and 
winter  tires  are  designed  for 
the  conditions  that  are  typical in those  seasons . Audi  recom
mends  using  winter  tires  dur
ing  the  winter  months . Low 
temperatures  significantly  de crease  the  elasticity  of  summ

and  b raking  ability.  If  summer 
tires  are  used  in very  cold 
temperatures,  cracks  can  form 
on  the  tread  bars,  resulting  in  permanent  tire  damage  that 
can  cause  loud  driving  noise 
and  unbalanced  tires. 
-Burnished,  polished  or  chromed  rims  must  not  be used  in winter  driving  condi
