Checking  and  filling -
---------------------=----"=---------
0 Note 
• Before  winter  sets  in,  have  the  coolant  checked  to  see  if  the 
coolant  additive  in your  vehicle  is sufficient  to  meet  the  climate 
conditions.  This  is especially  important  if you  live  in  a region  where 
the  winter  is  extremely cold.  If necessary,  increase  the  proportion  of 
coolant  additive  to  60%. 
•  When  adding  coolant  additive  to  your  cooling  system, 
remember: 
-We  recommend  using  only  coolant  additive  G12+ + (check  the 
label)  for your  vehicle.  This  coolant  additive  is available  at autho
rized  Audi  dealers.  Other  types  of  antifreeze  can  significantly 
reduce  corrosion  protection . The resulting  corrosion  can  cause  a 
loss  of  coolant  and  serious  engine damage . 
•  Do  not  add  any  type  of  radiator  leak  sealant  to  your  vehicle's 
engine  coolant.  Adding  radiator  repair  fluid  may adversely  affect  the 
function  and  performance  of  your  cooling  system  and  could  result 
in  damage  not  covered  by  your  New  Vehicle  Limited  Warranty .• 
Checking  the  engine  coolant  level 
The  engine  coolant  level  can  be  checked  with  a quick 
glance. 
Fig . 175  Engine 
compartment : coolant 
expansion  tank 
Before  you  check  anything  in  the engine  compartment, 
always  read  and  heed  all  WARNINGS==> & in  "Working  in 
the  engine  compartment"  on 
page 225. 
Turn  off  the  ignition. 
Read  the engine  coolant  level  from  the coolant  expan
sion  tank==>  fig.  175. With  a cold  engine,  the  coolant  level 
should  be between  the "min"  and  "max"  markings.  When 
the  engine  is warm,  the level  may  be  slightly  above  the 
" max"  marking. 
The location  of  the  coolant  expansion  tank  can  be  seen  in  the 
engine  compartment  illustration=> 
page 226. 
To obtain  an  accurate  reading, the  engine  must be  switched  off. 
The  expansion  tank  in  your  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 30will  blink  until  you  add  coolant  and  the 
level  has  been  restored  to  normal. Even though  there  is an  electric 
coolant  level  sensor,  we  still  recommend  you  check  the  coolant  level 
from  time  to  time. 
Coolant  loss 
Coolant  loss  may  indicate  a leak in  the cooling  system.  In the  event 
of  coolant  loss,  the cooling  system  should  be  inspected  immedi
ately  by your  authorized  Audi  dealer.  It is  not  enough  merely  to  add 
coolant. 
In  a 
sealed system,  losses can  occur  only  if  the  boiling  point  of  the 
coolant  is  exceeded  as a result  of  overheating. 
0 Note 
Do not  add  any type  of  radiator  leak sealant  to  your  vehicle's  engine 
coolant.  Adding  radiator  repair  fluid  may  adversely  affect  the  tune- _..

& WARNING 
•  Using incorrect  or unmatched  tires  and I or wheels  or improper 
tire  and  wheel  combinations  can  lead to  loss of control , collision 
and  serious  personal  injury . 
•  Always  use tires , rims  and  wheel  bolts  that  meet  the  specifica
tions  of original  factory-installed  tires  or  other  combinations  that 
have  been  specifically  approved  by the  vehicle  manufacturer. 
•  Tires age even  if they  are  not  being  used and  can fail  suddenly, 
especially  at  high speeds . Tires that  are  more than  6 years old can 
only  be  used  in an  emergency  and  then  with  special  care  and  at 
lower  speeds . 
•  Never  mount  used tires  on your  vehicle  if you  are  not  sure of 
their  "previous  history ." Old  used tires  may  have  been  damaged 
even though  the  damage  cannot  be  seen that  can  lead to  sudden 
tire  failure  and  loss of vehicle  control. 
& WARNING  (continued) 
•  All four  wheels  must  be fitted  with  radial  tires  of  the  same  type, 
size  (rolling  circumference ) and  the  same  tread  pattern.  Driving 
with  different  tires  reduces  vehicle  handling  and  can  lead  to  a loss 
of  control. 
•  If  the  spare  tire  is  not  the  same  as  the  tires  that  are  mounted 
on  the  vehicle  - for  e xample  with  winter  tires  - only  use  the  spare 
tire  for  a  short  period  of  time  and  drive  with  extra  care . Refit  the 
normal  road  wheel  as  soon  as  safely  possible. 
•  Never  drive  faster  than  the  maximum  speed  for  which  the  tires 
on  your  vehicle  are  rated  because  tires  that  are  driven  faster  than 
their  rated  speed  can  fail  suddenly . 
•  Overloading  tires  cause  heat  build-up , sudden  tire  failure , 
including  a  blowout  and  sudden  deflation  and  loss  of  control . 
•  Temperature  grades  apply  to  tires  that  are properly  inflated  and 
not  over  or  underinflated . 
•  For te chnical  reasons  it  is  not  always  possible  to  use  wheels 
from  other  vehicles  -in  some  cases  not  even  wheels  from  the 
same  vehicle  model. 
•  If you  install  wheel  trim  discs  on the  vehicle  wheels,  make  sure 
that  the  air  flow  to  the  brakes  is  not  blocked.  Redu ced  airflow  to 
the  brakes  can  them  to  overheat , increasing  stopping  distances 
and  causing  a collision. 
•  Run  flat  tires  may  only  be  used  on  vehicles  that  were  equipped 
with  them  at the  fa ctory . The vehicle  must  have  a chassis  designed 
for  run  flat  tires  and  a factory-installed  tire  pressure  monitoring 
system * that  indicates  a  loss  of  tire  pressure . Incorre ct  use  of  run 
flat  tires  can  lead  to  vehicle  damage  or  accidents . Check  with  an 
authorized  Audi  dealer  or  t ire  specialist  to  see  if  your  vehicle  can 
be  equipped  with  run  flat  tires . 
If run  flat  tires  are  used, they  must 
be  installed  on  all  four  wheels . Mixing  tire  types  is  not  permitted.  .,

•  For  technical  reasons,  it  is  not  genera lly  possible  to  use  the 
whee l rims  from  other  vehic les. This  can  hold  true  for  wheels  of  the 
same  vehic le type. 
•  If  the  spare  tire  is  different  from  the  tires  that  you  have  mounted 
on  your  vehicle  (for  example  winter  tires  or  wide  p rofile  t ires),  then 
use  the spare  tire  for  a short  period  of  time  only  and  drive  with  extra 
care.  Rep lace  the  flat  tire  with  the  tire  matching  the  others  on  your 
vehicle  as  soon  as  possible. 
•  If  you  put  d ifferent  wheels  and  tires  on  your  veh ic le (e.g.  w inter

Uniform  tire  quality  grading 
•  Tread  wear 
•  Traction  AA  A  B  C 
•  Temperature  A  B  C  Qua
lity  grades  can  be  found  where  applicable  on  the  tire  side  wall 
b etween  tread  shoulder  a nd  maximu m section  width  => 
page  255, 
fig.  184. 
For example : Tread  wear 200, Traction AA , Temperature A. 
All  passenger  car  tires  must  conform  to  Federa l Safety  Require 
ments  in  addit ion  to  these  grades. 
T read  wear 
The tread  wear grade  is  a comparative  rating  based  on  the  wear  rate 
o f  t he  tire  when  tes ted  under  contro lled  condit ions  on  a  specified 
government  test  course. 
F o r  example,  a  tire  g raded  150 would  wear  one  and  one  half  (1  1 /2) 
times  as well  on  the government  course  as a  tire  graded  100. 
The  relative  performance  of  tires  depends  upon  the  actual  condi 
tions  o f the ir  use,  however,  and  may  depart  sign ificantly  from  the 
norm  due  to  variations  in  driving  habits,  service  practices  and  differ 
ences  in  road  characterist ics  and  c limate . 
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  under  contro lled  cond itions  on  specified  government 
test  surfaces  of  asphalt  and  concrete.  A  tire  marked  C may  have 
poor  t raction  performance =>& . 
Temperature 
The temperature grades  are  A  (the  highest),  B, and  C, represent ing 
the  tire 's  resistance  to  the  generation  of  heat  and  its  ability  to  dissi 
pat e heat  when  tested  u nder  con tro lled  co nditions  on  a  specified 
indoor  laboratory  test  wheel. 
Sustained  high  tempera ture  can  cause  the  material  of  t he ti re  to 
degenerate  and  reduce  tire  life,  and  excessive  temperature can  lead 
to  sudden  tire  failure=>& . 
The  grade  C corresp onds  to  a  level  of  performance  which  all 
passenger  car  tires  must  meet  under  the  Federa l Motor  Vehicle

performa nce on  th e  la boratory  test  w hee l tha n the  minim um 
requ ired  by  law . 
& WARNING 
The traction  grade  assigned to this  t ire is based on straight-ahead 
braking  traction  tests , and  does  not  include  acceleration , 
cornering , hydroplaning  or  peak  traction  characteristi cs. 
& WARNING 
The  temperature  grade  for  this  tire  is established  for  a tire  th at  is 
properly  inflated  and  not  overloaded.  Exces sive speed , underinfla

All  pressure  warning  indicators in the  display  will  be  canceled. 
Fo llowing  each intent ional change  in  specified  pressures,  tire  pres
sures  must  be  saved  again . 
After  the  pressures  are  saved,  the tire  pressure  monitoring  system 
measures  the  current  tire  pressures  and  saves them  as the  new 
specified  pressures. 
[ i] Tips 
•  The  tire pressure  is shown  on  the  tire pressure  label.  The  tire 
pressure  label  is located  either on the  driver's  side  B -pillar  or on the 
inside  of  the  fuel  filler  flap. The  tire pressure  label lists the recom
mended  cold  tire  inflation  pressures  for  the  vehicle  at  its  maximum 
capacity  weight  and  the  tires  that  were  on  your  vehicle  at  the  time 
it  was  manufactured.  For  recommended  tire  pressures  for  normal 
load  conditions,  please  see  chapter~ 
page  247. 
• The tire  pressure  monitoring  system  helps  the  driver  monitor  tire 
pressures,  but  the  driver  is  still  responsible  for  maintaining  the 
correct  tire  pressure. • 
Applies  to  vehicles:  with  tir e  pressure  monitor ing  system 
Wheel  change 
If a  wheel  is  changed,  the  wheels  that  were  exchanged 
have  to  be  reprogrammed. 
- Turn  on  the  ignition. 
- Press the  button=> 
page 266, fig. 186 for  approximately  5 
seconds.  You  will  hear  a  beep and  the  symbol  in  the 
button  flashes  three  times. 
Programming  is  necessary: 
• after  the  tires  have  been  rotated on  the  vehicle,  or  the  spare  tire 
is  used,  • 
if  tires  with  new  wheel  sensors  are  used. 
All  pressure  warning  indicators  in the  display  will  be canceled.  The 
system  malfunction  error  message will  not  disappear  until  the 
vehicle  is underway.  With  pressing  the  button~ 
page  266, fig.  186, 
the  reprogramming  of  the  new  sensors  and  storing  of  actual  pres
sures  starts . This  learning  phase  can  take  up  to  10 minutes  driving 
time. 
During  the learning  process  the  tire pressure  monitoring  system  is 
not  available. • 
Applies  to  vehic les:  with  tir e  pr essure  monitor ing  system 
Malfunctions * 
A  malfunction  can  have  various  causes. 
Fig. 187  Display: 
System  malfunction 
If the '-warning  light  in  the  instrument  cluster  flashes  for  approxi 
mately  one  minute  and  then  remains  continuously illuminated  and 
additionally  the 
~ f ig.  187 symbol  appears  in the  display,  the 
tire  pressure  monitoring  system  is not  available . This  can  have 
various  causes. 
•  If  the  message  appears  at  the end  of  the  learning  process,  the 
system  cannot  recognize  the  wheels  installed  on  the vehicle . This 
can  be  because  one  or  more  wheels  without  a wheel  sensor  were 
installed.  .,,_

• A wheel  sensor  or  other  component  may  have failed. 
•  During  ini tializat ion the  system  has detected  more  tha n 4 wheels 
on  the  vehicle,  for  example  whi le driving  next  to  another  car  with  a 
tire  pressure  monitoring  system. 
•  A wheel  change  was  made  but  the  button 
:=:, page 266, fig.  186 
was  not  pressed. 
•  Audi  Genuine  Parts were  not  used  for  parts  replacement . 
•  If snow  chains  are  being  used,  system  function  can  be  compro
mised  due  to  the  shielding  properties  of  the  chains. 
•  The  tire  pressure  monitoring  system  may  not  be  avai lable 
because  of  a radio  malfunction. 
•  Transmitters  with  the  same  frequency,  such  as radio  head
phones  in the  vehic le or  radio  equipment,  can  cause  a temporary 
disruption  of  the  system  through  excessive  electromagnetic  fields . 
•  Eliminate  the  interference  if  possible  and  then  proceed  as 
follows:  Turn  off  the  engine  for  20 minutes.  Then  drive  another  10 
min.  If the  warning  light  comes  on  again,  you  shou ld con tact  your 
authorized  Audi  dealer  immediately  to  have  the  prob lem  corrected. 
•  Do not  use  commercially  avai lab le tire  sea lants . Otherwise,  the 
e lectrica l components  of  the  tire  pressure  monitoring  system  wi ll 
no  longer  work  properly  and  the  sensor  for  the  tire  p ressure  moni 
toring  system  wil l have to  be  rep laced  by an  authorized  Audi  dealer 
or  o ther  qua lified  workshop .•
