fig.  193 . 
With  a cold  engine,  the  coolant 
level  should  be  between  the  "min" and 
"max"  mar kings.  When  the  engine  is warm, 
the  leve l may  be  slightly  above  the  "max" 
marking. 
The  location  of  the  coolant  expansion  tank 
can  be  seen  in the  engine  compartment  illus
tration¢ 
page  229 . 
To obtain an  accurate  read ing,  the  eng ine 
must  be  switched  off. 
The expans ion tank  in you r vehicle  is  equipped 
with  an  electric  coolant  level  sensor . 
When  the coolant  level is  too  low,  the warning 
light  in the  Auto -Check  System ¢ 
page  17 will 
illum inate  u ntil  you  add  coolant  a nd  the  level 
has  been  restored  to  normal.  Even though 
there  is an  electric  coolant  level  sensor,  we 
still  recommend  you  check  the  coolan t  leve l 
from  time  to  time. 
Coolant  loss 
Coolant  loss  may  indicate  a leak in the  cool ing 
system.  In  the  event  of coolant  loss,  the  cool-
Checkin g and  fillin g 235 
ing  system  should  be  inspected  immediately 
by your  authorized  Audi  dealer . It  is not 
enough  merely  to  add  coolant. 
In  a 
s ea led system,  losses  can  occur  on ly if 
the  boiling  point  of the  coo lant  is exceeded  as 
a  result  of  overheating. 
A WARNING 
The  cooling  system  is  under  pressure  and 
can  get  very  hot.  Reduce  the  risk of  scald
ing  from  hot  coolant  by follow ing  these 
steps. 
- Turn  off  the engine  and  allow  it  to cool 
down. 
- Protect  your  face,  hands  and  arms  from 
escap ing  f lu id  and  steam  by cover ing  the 
cap  with  a  la rge,  th ick rag. 
- Turn  the cap  slowly  and very  carefully  in 
a  counter-clockwise  d irect ion  while  ap
plyi ng  light,  downward  pressure  on  the 
top  of the  cap  . 
- To avo id  being  burned,  do  not  sp ill anti
freeze  or  coolant  on  the  exhaust  system 
or  hot  engine  parts.  Under  certa in cond i
tions,  the  ethylene  gly col  in  engine  coo l
a nt  can  catch  fire. 
(D Note 
Do not  add  any  type  of  radiator  leak  sea L
ant  to  your  veh icle's  engine  coo lant . Add

twist  the  cap counter-clockwise  ¢ &_. 
• Add coolant  mixed in the  correct  ratio 
¢ page  234,  Coolant. 
• Twist the  cap on again tightly . 
Replacement  engine  coolant  must  conform  to 
exact  specifications  ¢ 
page  234, Coolant . 
We recommend  using on ly coo lant  addi-
tive 
Gl2++,  Gl3 or  in an emergency Gl2 +. Do 
not use a different  additive.  In an emergency 
use plain water  unt il you can get  the  correct 
addit ive and  can  restore  the  correct  ratio . This 
should  be done  as  soon  as  possible . 
If you have lost  a considerable  amount  of 
coolant,  then  you should  add  cold antifree ze 
and  cold water  only when  the  eng ine is co ld. 
A lways use 
new engine  coolant  when  refi lling. 
Do not fill coolant  above the  "MAX" mark.  Ex
cess  coolant  will be forced  out  t hrough the 
press ure relief valve in the  cap when  the  en
gin e becom es hot. 
A WARNING 
- The coo ling system  is under  p ress ure and 
can get  very hot.  Reduce the  risk of 
scalding  from  hot  coolant  by following 
these  steps . 
- Tu rn o ff the  eng ine a nd a llow i t to  cool 
down. 
- Pr otect  your f ace, hands  and  arms from 
escaping  f luid and  steam  by cover ing 
the  cap with  a  large,  thick  rag. 
- Tu rn  the cap slowly and very ca re fully 
in a counte r-clockwise direct ion while 
applying  light,  downwa rd  p ress ure on 
the  top  of the  cap. 
- To avoid being  burned,  do  not spi ll an 
tifreeze  or coolant  on the  exhaust  sys
tem  or hot  engine  parts.  Under certa in 
conditions,  the  ethylene  glyco l in en
g ine coolant  can catch f ire. 
- Antifreeze  is poisonous.  Always store  an
t ifreeze  in its original  container  and well 
out  of the  reach of children.  -
If  you drain the  coo lant,  it  m ust  be 
caught  and safely stored  in a proper  con
tainer  clearly marked  "poison". 
(D Note 
- Coo lant  poll utes  the  environment  and 
cou ld cause  an engine  fire . Excess cool
ant  will be forced  out  through  the  pres
sure  relief valve  in the  cap when  the  en
gine  becomes  hot . 
- If, in an emergency,  only water  can  be 
added,  the  correct  ratio  between  water 
and  antifreeze  ¢

Changing  brake  fluid 
Have  the  brake  fluid  changed  by an  experi
enced  technician . 
Brake  fluid  absorbs  mois ture  from  the  air.  If 
the  wa ter  content  in  the  brake  fluid  is  too 
high , corrosion  in the  brake  system  may  result 
after  a  period  of  time . The  boiling  point  of  the 
brake  flu id  will  also  dec rease  considerably  and 
decrease  braking  pe rformance. 
Therefore,  the  brake  fluid  must  be  changed 
ev ery two  years. Always  use  new  brake  flu id 
which  conforms  to  Federal  Motor  Vehicle 
Standard  "F MVSS 116  DOT 4 ". 
The  brake  fluid  reservo ir can  be  d iff icult  to 
reach,  the refore,  we  recommend  that  you 
have  the  brake  fluid  changed  by your  author
i zed 
Audi  dealer . Your dealer  has  t he correct 
tools,  the  right  brake  fl uid and  the  know-how 
to  do  this  for  you. 
A WARNING 
-
- Brake fluid  is  poisonous . It  must  be  stor
ed  only  in the  closed  original  container 
out  of  the  reach  of  children! 
- Brake failure  can  resu lt  from  o ld  or  inap
propriate  brake  f luid.  Observe  these  pre
cautions: 
- Use  only  brake  fluid  that  meets  SAE 
spec ificat ion 
J 1 7 03  and  conforms  to 
Federa l Moto r Ve hicl e  Standard  116. 
Always  check  with  yo ur authorized  Audi 
dealer  to  make  sure  yo u are  using  the 
correct  bra ke fluid.  The  correct  type  of 
brake  f luid  is  also  indicated  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 
l ong . This  can  seriously  affect  the  effi 
c iency  of  the  brakes  as  well  as  your 
safety.  Th is cou ld  resu lt  in an  accident .

Cord 
means  the  strands  forming  the  plies  in the 
tire .  typ
ica l in those  seasons . Audi  recommends 
using  winter  tires  during  the  winter 
months . Low temperatures  signif icant ly 
decrease  the  e lasticity  of  summer  tires, 
which  affects  tract ion  and  brak ing  ability. 
If  summer  tires  are  used  in very  co ld tem
peratures,  cracks  ca n form  on  the  tread 
bars,  res ulting  in  permanent  tire  damage

-The  use  of  incorrect  tire  pressure  values 
can  lead  to  accidents  or  other  damage. 
Therefore  it  is essential  that  the  driver  observe  the  specified  tire  pressure  values 
for  the  tires  and  the  correct  pressu res  for 
the  funct ion  of  the  tire  pressure  mon itor
ing  system*. 
- Always  inflate  t ires  to  the  recommended

Tires and vehicle  load  limits 
There  are  limits  to  the  amount  of  load  or 
weight  that  any  veh icle  and  any  t ire  can  carry . 
A vehicle  that  is overloaded  w ill not  handle 
well  and  is more  difficult  to  stop . Overload ing 
can  not  on ly lead  to  loss  of  vehicle  con trol, 
b ut  can  a lso  damage  important  par ts of  the 
vehicle  and  can  lead  to  sudden  tire  failure,  in
cluding  a  blowout  and  sudden  deflation  that 
can  cause  the  vehicle  to  crash. 
Tire s an d wheel s 251 
Your safety  and  that  of  your  passengers  also 
depends  on  making  sure  that  load  limits  are 
not  exceeded.  Vehicle  load  includes  everybody 
and  everything  in  and  on  the  veh icle.  These 
load  lim its  are  technically  referred  to  as  the 
vehicle's 
Gro ss Ve hicle  Wei ght  R ating 
("GVWR") . 
The  "GVWR" includes  the  weight  of  the  basic 
vehicle,  all  factory  installed  accessories,  a  full 
tank  of  fuel,  o il, coolant  and  other  fluids  plus 
maximum  load.  The  max imum  load  includes 
the  number  of  passengers  that  the  vehicle  is 
in tended  to  carry  ("seat ing  capac ity")  with  an 
assumed  we ight  of  150  lbs  (68  kg) for  each 
passenger  at  a  designated  seating  posit ion 
and  the  total  weight  of  any  luggage  in the  ve hicle . If  you  tow  a  trai ler,  the  weight  of  the 
trailer  hitch  and  the  tongue  weight  of  the 
loaded  tra iler  must  be  included  as  part  of  the 
vehicle  load. 
The 
Gr oss  Ax le We ight  R ating ("GAWR") is 
the  maximum  load  that  can  be  applied  at  each 
of  the  vehicle's  two  axles. 
The  Gross  Vehicle  Weight  Rating  and  the 
Gross  Axle Weight  Rating  are  listed  on  the 
safety  comp liance  sticker  label  located  on  the 
driver's  side  B-pillar.  Your Audi  has  4  seat ing 
pos itions,  2  in the  front  and  2  in the  rear  for 
total  seating  capacity  of  4 . In  some  vehicles 
there  are  5  seating  pos it ions,  2  in the  front 
and  3  in the  rear  for  tota l seating  capacity  of 
5.  Each seat ing  position  has  a  safety  belt 
~ page  140,  Safety  belts . 
The  fact  that  there  is a n upper  limit  to  you r 
vehicle's  Gross  Vehicle  Weight  Rating  means 
that  the  total  weig ht  of  whatever  is being  car
ried  in the  vehicle  ( includ ing  the  weight  of  a 
trailer  hitch  and  the  tongue  weight  of  the 
loaded  trai ler)  is  limited . The  more  passen
