and  have  the  cooling  system  inspected.  If  the 
cooling  system  is not  leaking,  a  loss  can  come 
from  the  coolant  boiling  through  overheating  and  being  pushed  out  of  the  cooling  system. 
A WARNING 
- The  cooling  system  is  under pressure.  Do 
not  open  the  coolant  expansion tank  cap 
when  the  engine  is hot. This increases  the 
risk  of  burns . 
- The  coolant  add itive  and  the  coolant  can  be 
dangerous  to  your  health. For this  reason, 
keep  the  coolant  in  the original  container 
and  away  from  children.  There  is a  risk  of 
poisoning. 
- When  working  in the  engine  compartment, 
remember  that  the radiator  fan  can  switch 
on  even  if the  ignition  is switched  off, which 
increases  the risk  of  injury. 
(D Note 
Do not  add  coolant if the  expansion  tank is 
empty.  There may  be  a ir in the  cooling  sys
tem,  which  increases  the  risk  of  engine  dam
age . If  this  is the  case,  do  not  continue  driv

Brake  fluid 
Checking brake fluid  level 
The brake  fluid  level  can be checked with  a quick 
glance . 
Fig. 250 Engine  compa rtment:  Cover o n the brake  fluid

Before  you  check  anything  in the  eng ine  compart 
ment, 
always  read and  heed all  WARNINGS 
Checking  and  Filling 
c::> .&. in Working  in  the  engine  compartment  on 
page  304. 
"  Read  the brake  fluid  level  from  the  brake  fluid 
reservoir 
c::> fig.  250, c::> page  306,  fig.  247. The 
brake  fluid  level must  be  between  the "MIN" 
and  "MAX"  markings. 
The  brake  flu id  reservoir  is  located  at  the rear 
partition  of  the  engine  compartment  on  the  left 
side 
~ page  306 . 
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/indicato r 
light  (USA models: 
11111 , Canada  models : II> 
will  come  on c::> page 29.  Do not  continue  to oper
ate  the  vehicle.  The  complete  brake  system 
should  be  thoroughly  checked  by an  authorized 
Audi  dealer  or  qualified  workshop  and  the  cause 
corrected . If  the  brake  fluid  level  is too  low,  the 
brake  warning/indicator  light  will  illuminate . 
Contact  an  authorized  Audi  dealer 
immediately . 
@ Tips 
The  brake  fluid  reservoir  is located  under
neath  the  cover. 
Changing  brake fluid 
Hove the  broke  fluid  changed  by on 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  ape
riod  of  time.  The  boiling  point  of  the  brake  fluid 
will  also  decrease  considerably  and  decrease  braking  performance . 
Therefore,  the  brake  fluid  must  be  changed 
every 
two  years . 
Always  use  new  brake  fluid  which  con
forms  to  Federal  Motor  Vehicle  Standard  "FMVSS 
116 DOT 4" . 
The  brake  fluid  reservoir  can  be  difficult  to  reach, 
therefore,  we  recommend  that  you  have  the  brake  fluid  changed  by your  authorized 
Audi 
dealer.

To reduce  the  risk  of  lime  sca le  deposits  on  the 
spray  nozzles,  use  clean  water  with  low  amounts 
of  calci um.  Always  add  window  cleaner  to  the  wa
t er.  When  the  outside  temper atures  are  co ld,  an 
anti-free zing  agent  should  be  added  to  the  water 
so that  it does not freeze . 
Cl) Note 
-The  concentration  of  anti-free zing  agent 
must  be  adjusted  to  the  vehicle  operating 
conditions  in the  respective  climate.  A con 
centration  that  is too  high  can  lead  to  veh i
cle  damage . 
- Never  add  rad iator  anti -freeze  or  other  addi 
tives  to  the  washer  fluid . 
- Do not  use  a  glass  cleaner  that  contains 
paint  solvents,  beca use  this  could  damage 
the  pa int.

Treadwear  indicator 
Original  equipment  tires  contain 
treadwear indicators in the  tread 
pattern,  which  are  bars  that  are  1/16  in  (1.6  mm)  high  and  are 
spaced  evenly  around  the  tire  per pendicular  to  the  running  direc
tion 
c::> fig. 254 . The  letters  "TWI" 
or  triangles  on  the  tire  sidewall  indicate  the  location  of  the  tread
wear  indicators. 
The  tires  have  reached  the  mini
mum  tread  depth 
l) when  they 
have  worn  down  to  the  treadwear 
indicators.  Replace  the  tires  with 
new  ones 
c::> A . 
Tire  rotation 
Rotating  the  tires  regularly  is rec
ommended  to  ensure  the  tires 
wear  evenly.  To  rotate the  tries, 
install  the  tires  from  the  rear  axle 
on  the  front  axle  and  vice  versa. 
This  will  allow  the  tires  to  have 
approximately  the  same  length  of 
service  life. 
For  unidirectional  tires,  make 
sure  the  tires  are  installed accord
ing  to  the  running  direction  indi-

Hidden  damage 
Damage  to  tires  and  rims  can  of
ten  occur  in  locations  that  are 
hidden.  Unusual  vibrations  in the 
vehicle  or  pulling  to  one  side  may  indicate  that  there  is tire  damage . 
Reduce  your  speed  immediately. 
Check  the  tires  for  damage.  If  no 
damage  is visible  from  the  out
side,  drive  slowly  and  carefully  to 
the  nearest  authorized  Audi  deal
er  or  authorized  Audi  Service  Fa
cility  to have  the  vehicle  inspect
ed. 
A WARNING 
Tread  that  has  worn  too  low  or  different  tread  depths  on  the 
tires  can  reduce  driving  safety. 
This  can  especially  have  a  nega
tive  effect  on  handling,  on  the  risk  aquaplaning  when  driving 
through  water,  when  driving 
through  curves  and  when  brak ing,  which  increases  the  risk  of 
an  accident.

-Traction  AA A BC 
- Temperature  ABC 
Quality grades  can  be found  where  applicable  on 
the  tire  side wall between  tread  shoulder  and  maximum  section  width 
~ page  317,  fig. 253. 
For example: Tread wear 200, Traction AA, Tem 
perature 
A . 
All passenger  car tires  must  conform  to  Federal 
Safety  Requirements  in addition  to  these  grades. 
Tread  wear 
The tread  wear grade  is a comparative  rating 
based  on the  wear  rate  of the  tire  when  tested 
under  controlled  conditions  on a specified  gov
ernment  test  course. 
For  example,  a tire  graded  150  would wear  one 
and  one  half 
(1  1/2) times  as well on the  govern 
ment  course  as a tire  graded  100. 
The relative  performance  of tires  depends  upon 
the  actual  conditions  of their  use,  however , and 
may  depart  significantly from  the  norm  due to 
variations  in driving habits,  service practices  and 
differences  in road  characteristics  and  climate. 
Traction 
The traction grades,  from  highest  to  lowest,  are 
AA, A, Band 
C. Those  grades  represent  the  tire's 
ability to  stop  on wet  pavement  as  measured  un
der  controlled  conditions  on specified  govern 
ment  test  surfaces  of asphalt  and  concrete.  A tire 
marked  C may have poor  traction  performance 
~ .&  . 
Temperature 
The temperature grades  are  A (the  highest), B, 
and  C, representing  the  tire's  resistance  to  the 
generation  of  heat and  its ability to  dissipate 
heat  when  tested  under  controlled  conditions  on 
a specified  indoor  laboratory test  wheel. 
Sustained  high temperature  can cause  the  mate rial of the  tire  to  degenerate  and  reduce  tire  life, 
and  excessive temperature  can  lead to  sudden 
tire  failur e~ ,& . 
The grade  C corresponds  to  a  level of perform
ance which all passenger  car tires  must  meet  un-
334 
der  the  Federal  Motor  Vehicle Safety Standa rd 
No. 109.  Grades Band  A represent  higher  levels 
of  performance  on the  laboratory  test  wheel  than 
the  minimum  required by law. 
A WARNING 
,--
The traction  grade  assigned  to  this  tire  is 
based  on straight -ahead  braking  traction 
tests,  and  does  not  include acceleration,  cor nering,  hydroplaning  or peak  traction charac
teristics . 
A WARNING 
The temperature  grade  for this  tire  is estab
lished  for  a tire  that  is properly  inflated and 
not  overloaded.  Excessive speed,  underinfla
tion,  or excessive  loading, either  separately  or 
in combination,  can cause  heat  buildup  and 
possible  tire  failure. 
A WARNING 
Temperature  grades  apply to  tires  that  are  properly  inflated  and  not  over or  underinflat
ed. 
Tire  pressure  monitoring  indicator 
(l) General  notes 
-
Each tire,  including the  spare  (if provided), 
should  be checked  monthly  when  cold and  inflat
ed to  the  inflation  pressure  recommended  by the 
vehicle manufacturer  on the  vehicle placard  or 
tire  inflation  pressure  label. (If your vehicle has 
tires  of a different  size than  the  size indicated  on 
the  veh icle  placard  or tire  inflation pressure  la
bel, you should  determine  the  proper  tire  infla
tion  pressure  for  those tires). 
As an  added  safety  feature,  your vehicle  has been 
equipped  with  a tire  pressure  monitoring  system 
(TPMS) that  illuminates  a  low tire  pressure  tell
tale  when  one or  more  of your tires  is significant ly  under-inflated.  Accordingly, when  the  low tire 
pressure  telltale  illuminates,  you should  stop  and 
check your tires  as soon  as  possible,  and  inflate 
them  to  the  proper  pressure.  Driving on a
