(D Tips 
- Check  the  depth  of  the  water  before  driving 
through  it. 
- Do not  stop  the  veh icle,  drive  in  reverse  or 
switch  the  engine 
off when  driving  through 
water. 
- Keep  in  mind  that  oncoming  vehicles  may 
create  waves  that  raise  the  water  level  and 
make  it too  deep  for  your  vehicle  to  dr ive 
through  safely. 
- Avoid driving  through  sa lt  water  because  it 
can  cause  corrosion. 
Catalytic  converter 
It  is very  important  that  your  emission  control 
system  (catalytic  converter)  is functioning  prop erly to ensure  that  your  vehicle is running  in an 
environmentally  sound  manner . 
~ Always  use  lead-free gasoline¢ page  186, 
Fuel supply . 
~ Never  run  the  tank  down  a ll the  way to  empty . 
~ Never  put  too  much  motor  oil  in your  engine 
¢ page  195, 9::?1 Adding  engine  oil  . 
~ Never try to  push- or tow -start  your  veh icle. 
The cata lytic  conve rter  is an  eff icient  "clean-up" 
dev ice  bu ilt  into  the  exhaust  system  of  the  vehi
cle.  The  cataly tic converter  burns  many  of  the 
pollutants  in the  exhaust  gas  before  they  are  re 
leased  into  the  atmosphere. 
The  ex clusive  use  of  u nleaded  fuel  is critically  im
por tant  for  the  life  of the  catalyt ic converte r and 
p roper  functioning  o f the  engine. 
A WARNING ,..___ -
- The  temperature  of  the  exhaust  system  is 
high,  both  when  driving  and  after  stopping 
the  engine. 
- Never  touch  the  exha ust  tail  pipes  once  they 
have  become  hot.  This could  result  in  burns. 
- Do not  park  o r operate  the  vehicle  in  areas 
whe re the  hot  exhaust  system  may  come  in 
contact  with  dry  grass,  brush,  fue l spill  or 
other  mater ial  which  can  cause  a fire. 
- Do not  apply  additional  undercoating  or 
rustproofing  on  or  near  the  exha ust  man i-
178 
fold,  exha ust  pipes,  catalytic  converter  or 
heat  shields.  During  driv ing,  the  substance 
used  for  undercoat ing  could  overheat  and 
cause  a f ire. 
Cl) Note 
- Be aware  that  just  one  tank  fill ing  with 
le ad· 
ed 
fue l w ill  already  ser iously  degrade  the 
performance  of the  catalytic  converter. 
- Do not  exceed  the  correct  engine  oil  level 
¢page  195. 
-Do not  drive  until  the  fue l tank  becomes 
completely  empty.  The  engine  co uld  m isfire. 
Unburned  fuel  could  also  get  into  the  ex
haust  system  and  this  could  cause  the  cata
lyt ic converter  to  overheat. 
- Do not  turn 
off the  ignition  while  the  vehicle 
is  moving . 
- Do not  continue  to  operate  your  veh icle  un
der  these  conditions,  as  otherwise  fuel  can 
reach  the  catalytic  converter . This  could  re
sult  in  overheating  of  the  conve rter,  requ ir
ing  its  replacement. 
- T o assure  efficient  operation  of  the  Emission 
Cont ro l System: 
- Have your  vehicle  maintained  properly  and 
in  accordance  with  the  se rvice recommen
dations  in yo ur Warranty 
& Maintenance 
booklet. 
- Lack  of  proper  maintenance  as  we ll as  im
proper  use  of the  vehicle  will  impair  the 
function  of the  emission  control  system 
and  could  lead  to  damage. 
(® For the  sake of  the  environment 
Even when  the  Emiss ion  C ontrol  System  is op
e rat ing  proper ly, the  exhaust  gas  can  have  a 
sulfur-like  exhaust  gas  sme ll under  some  op
erat ing  states.  This  depends  on  the  sulfur 
content  of  the  fuel  being  used.  Us ing  a  d iffe r

By having  your  vehicle  regularly  serviced  by an 
authorized  Audi  dealer  he lps  to  ensure  that  it 
runs  properly  and  economically.  The  condition  of 
your  vehicle  not  only  affects  its  safety  and  ability  to  hold  its  value,  it  also  affects 
f uel c onsump

·  Fewer  short  trips 
Fuel consumption  will always  be  relatively  high 
on short  trips  . 
.,. Try to  avoid  dr iv ing  short  distances  with  a  cold 
eng ine . 
The  eng ine  and  catalytic  converter  have  to  reach 
their  opt imal 
oper atin g temperature to  reduce 
fuel  consumpt ion  and  noxious  emissions  effec
tively . 
Just  after  starting,  a  co ld  engine  in a  mid-s ize  car 
on ly achieves  a fuel  economy  of  6-8  mi les  per 
gallon  (30-40  l/100  km).  After  about  a  half  a 
mile,  fuel  economy  climbs  to  12  mpg  (20  l/100 
km) . After  about 
2.5 miles  (4  km),  the  eng ine  is 
at  its  proper  operating  temperature  and  fuel 
economy  has  reached  a  norma l level.  So you  can 
see  that  you  should  avo id  short  trips whenever 
poss ible . 
The 
out side t emp eratur e is also  cr itical  in th is  re
gard.  Your car  consumes  more  fuel  in the  winter 
than  in the  summer.

Trailer  mode 
Tire pressure 
When tow ing a trailer,  inflate  the  tires of your ve
hicle to  the cold tire  pressure  listed  under  " Full 
load" on the  label  located  on the  driver's side  B 
pillar (visible when  the  door  is open).  Inflate 
trailer  tires  to  trailer  and tire  manufacturers' 
specifications. 
Lights 
The  headlight  settings  should  be checked with 
the  trailer  attached  before driving off . Check to 
make sure  both  vehicle and  trailer  lights  are 
working properly. 
Safety  chains 
Be  su re  trailer  safety chains  are properly  connect
ed from  the  trailer  to the  hitch on  the vehicle. 
Leave  enough  slack in the  chains  to  permit turn
ing corners.  When you  install safety  chains,  make 
sure  they will not  drag  on the  road when  you are 
driving. 
The chains  shou ld cross under  the  trai ler tongue 
to  prevent  it from  dropping  in case  of separation 
from  the  hitch. 
Driving  instructions 
Driving  with  a trailer  always  requires  extra  care 
and  consideration. 
To obtain  the  best  possible handling  of vehicle 
and  trai ler,  please  note  the  following: 
..  Do  not tow  a loaded  trailer  when your car  itself 
is not  loaded  . 
..  Be especia lly careful when  passing  other 
vehicles. 
..  Observe speed  limits. 
..  Do not  drive at  the  maximum  permissible 
speed . 
..  Always apply  brakes  early. 
..  Monitor the  temperature  gauge. 
Weight  distribution 
Towing a  loaded  trai ler with an empty  car  results 
in a highly unstable  distribution  of weight.  If this 
cannot  be avoided,  drive at  very low speeds  only 
to  avoid  the  risk of  losing steering  control. 
182 
A "balanced"  rig is easier  to operate  and  contro l. 
This means  that  the  tow vehicle shou ld be loaded 
to  the  extent  possible  and  permissib le, wh ile 
keep ing the  trailer  as  light  as  possible  under  the 
c ir cumstances.  Whenever  poss ible, transfer 
some  cargo to  the  luggage  compartment  of the 
tow veh icle while observing  tongue  load  require
ments  and  vehicle  load ing considerat ions . 
Speed 
The higher  the  speed,  the  more  difficult  it be
comes  for the  driver to  control  the  rig. Do  not 
drive at  the  maximum  permissible  speed.  Reduce 
your speed  even more  if load, weather  or w ind 
cond it ions  are  unfavorab le  - particularly  when 
go ing downh ill. 
Reduce veh icle speed 
immediately if the  trailer 
shows  the  slightest  sign of swaying. 
Do not try 
to  stop the  swaying by  accelerating. 
Observe speed  limits.  In some  areas,  speeds  for 
vehicles towing  tra ilers  are  lower than  for  regular 
vehicles. 
Always apply  brakes  early. When  dr iving down
hill,  shift  into  a  lower  gear  to  use the  engine 
braking  effect to  slow  the vehicle.  Use of the 
brakes  alone  can cause  them to  overheat  and  fail. 
Coolant  temperature 
The coolant  temperature  gauge¢ page  10 must 
be observed  carefully. If the  needle  moves close 
to  the  upper  end  of the  scale,  reduce speed  im
med iately  and/or  turn off the  air conditioner  . 
If the  coolant  temperature  warning  light . in 
the  instrument  cluster  starts  flashing,  pull off 
the  road,  stop  and  let the  engine 
idle for  about 
two  m inutes  to  prevent  heat build-up  . 
&_ WARNING 
Anyone not  properly restrained  in a moving 
vehicle  is  at a much  greater  risk  in an  acci
dent.  Never let anyone  ride  in your car who is 
not  properly  wearing the restraints  provided 
by Audi.

restored  to  normal.  Even though  there  is an e lec
tr ic coo lant  level sensor,  we still  recommend  you 
check the  coo lant  level from  t ime to  time. 
Coolant  los s 
Coolant  loss  may indicate  a leak in t he cooling 
system.  In the  event  of coolant  loss, the  cooling 
system  should  be inspected  immediately  by your 
authorized  Audi dealer.  It  is not  enough  merely 
to  add  coolant. 
I n a 
s e a led system,  losses  can occur only if the 
boiling point  of the  coo lant  is exceeded  as a  re
sult  of overheating. 
A WARNING 
The cooling system  is under  pressure  and  can 
get  very hot.  Reduce the  risk of scalding from 
hot  coolant  by following  these  steps . 
- Turn off the  engine  and  allow it to  coo l 
down . 
- Protect  your face,  hands  and  arms  from  es
caping fluid  and  steam  by covering the  cap 
with  a  large, thick  rag . 
-Turn the  cap slowly and  very carefully in a 
counter-clockw ise  d irection while applying 
light,  downward  pressure  on the  top  of the 
cap. 
- To avoid being  burned,  do not  spill ant i
freeze  or coolant  on the  exhaust  system  or  hot  eng ine parts . Under ce rtain  conditions, 
the  ethy lene  g lycol  in engine  coolant  can 
catch fire.

Radiator  fan 
The radiator  fan  switches  on  automatically  by it
self. 
The  radiator  fan  is driven  by the  engine  via the  V
be lt . The  viscous  clu tch  regulates  the  speed  of 
the  fan  ac cording  to  the  temperature  of the  cool 
ant. 
An auxiliary  e lectr ic rad iator  fan*  switches  on  and 
off  depend ing  on  coolant  temperat ure  and  othe r 
veh icle  operati ng  conditions. 
Afte r you  switch  the  engine  off, the  auxiliary  fan 
can  continue  runn ing  for  up  to  10  minutes  -even 
Ch eck in g  and  Fillin g 
with  the  ignition  off . It  can  even  sw itch  on  again 
later  by  itself¢& , if 
- the  temperatu re  of the  engine  coo lant  rises  due 
to  the  heat  build- up from  the  engine  in the  en
gine  compartment,  or 
- the  engine  compartment  heats  up  because  the 
veh icle  is  parked  in  intense  sun light . 
A WARNING 
-To reduce  the  risk of  persona l injury  never 
touch  the  radiator  fan . 
- The  auxiliary  electric  fan  is temperature  con trolled  and  can  switch  on  suddenly  even 
when  the  engine  is  not  running. 
- The  a uxiliary  radiator  fan  sw itches  on  auto

{D) Tips 
The  brake  fluid  reservoir  is located  under
neath  the  cove r. 
Changing  brake  fluid 
Have the  brake  fluid  changed  by an  experienced 
technician . 
Brake fluid absorbs  moist ure from  the  a ir. If  the 
water  content  in the  brake  fluid  is too  high,  cor rosion  in the  brake  system  may  result  after  a  peri
od  of time . The  boiling  point  of the  brake  flu id 
w ill also  decrease  conside rably  and  dec rease 
b rak ing  perfo rmance. 
Therefore,  the  brake  flu id  must  be  changed 
e ve ry 
two year s. 
Always use  new  brake  fluid  w hich  con
forms  to  Fede ral  Motor  Vehicle  Standard  "FMVSS 
1 16  DOT  4". 
The  brake  fluid  rese rvoir can  be  difficult  to  reach, 
therefo re , we  recommend  that  you  have  the 
b rake  fluid  changed  by your  author ized 
Audi 
dealer . 
Your  dealer  has  the  correct  too ls ,  the 
right  brake  fluid  and  the  know-how  to  do  t his for 
you. 
A WARNING 
- B rake  fluid  is  poisonous.  It  must  be  stored 
on ly in the  closed  original  container  out  of 
the  reach  of  children! 
200 
- Brake fail ure  can  resu lt  from  o ld  or  inappro
priate  brake  fluid.  Observe  these  precau 
tions: 
- Use  only  b rake  fluid  that  meets  SAE spec i
f ica tion 
J 170 3  and  conform s to  Federa l 
Motor  Vehicle  Standard  116.  Always check 
with  yo ur autho rized  Audi  dea le r to  make 
su re you  are  using  the  correct  brake  fl uid. 
The  correct  type  of  brake  flu id  is also  ind i
cated  on  the  brake  fluid  reservoir. 
- The  brake  fl uid  must  be  new.  Heavy use  of 
the  brakes  can  cause  a vapor  lock  if the 
brake  f luid  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  acc ident.

Wheels 
A WARNING 
Wheel  bolts  that  are tightened  or  repaired  incorrectly  can become  loose  and  result  in  loss 
of  vehicle  control , which  increases the  risk of 
an accident.  For the  correct  tightening  specifi
cation,  refer  to 
c:> page 22 7, After  changing  a 
wheel. 
- Always  keep the  wheel  bolts  and the  threads 
in the  wheel  hub  clean and free  of  grease. 
- Only  use wheel  bolts  that  fit  the  rim . 
- Always  have  damaged  rims  repaired  by an 
authorized  Audi  dealer  or authorized  repair 
facility.  Never repair  or  disassemble  rims 
yourself,  because this  increases the  risk of  an accident. 
Winter  tires 
Winter  tires  significantly  improve  the  vehicle's handling  when  driving  in winter  conditions . Be
cause of  their  construction (width,  compound, 
tread  pattern),  summer  tires  provide  less traction 
on  ice  and snow. 
..,  Use  winter  tires  on  all  four  wheels . 
..,  Only use winter  tires  that  are approved  for  your 
vehicle. 
..,  Please note  that  the maximum  permitted 
speed may be lower  with  winter  tires 
c:> .&,. 
Your authorized  Audi  dealer  or  authorized  re
pai r facility  can inform  you about  the  maximum 
permitted  speed for  your  tires . 
..,  Check the  tire  pressure  after  installing wheels 
c:> page  215. 
The effectiveness  of  winter  tires  is reduced  great
ly when  the  tread  is worn  down  to  a depth  of 
0 .1S7 inch  (4  mm).  The characteristics  of  winter 
tires  also decrease greatly  as the  tire  ages, re 
gardless  of  the  remaining tread. 
A WARNING 
-Never  drive  faster  than  the  maximum  per
mitted  speed  for your  t ires.  This could  cause 
the  tires  to  heat  up too much . This  increases 
the  risk of  an accident  because it  can cause 
the  tire  to  burst. 
220 
- Always  adapt  your  driving  to  the  road and 
traffic  conditions.  Drive carefully  and  reduce 
your  speed on  icy or  slippery  roads.  Even 
winter  tires  can lose traction  on  black  ice. 
@ For the sake of the  environment 
Reinstall  summer  tires  at  the  appropriate 
time,  because they  provide  better  handling 
when  roads  are free  of  snow  and  ice. Summer 
tires  cause  less road  noise,  tire  wear  and fuel 
consumpt ion. 
(D Tips 
You can also  use all  season tires  instead  of 
winter  tires.  Please note  that  in  some coun
tries  where  winter  tires  are required,  only win
ter  tires  w ith  the 
& symbol  may be permit
ted. 
·  Snow chains 
Snow  chains  improve  traction  in  the  snow . 
.., Only install  snow  chains on the front wheels. 
This applies  also to  vehicles with  all  wheel  drive* . 
..,  Check and  correct  the  seating  of  the  snow 
chains if  necessary after  driving  a few  feet.  Fol
low  the  instructions  from the manufacturer . 
..,  Note  the  maximum  permitted  speed when  driv
ing with  snow  chains . Do not  exceed 30  mph 
(SO km/h) . 
Snow chains  not  only  improve  the 
driving in win
ter  road  conditions,  but  also  the 
braking. 
Use of  snow chains  is only  permitted  with  certain 
rim/tire  combinations  due to technical  reasons. 
Check  with an authorized  Audi  dealer  or  author
ized  repair  facility  to  see if  you  may use snow 
chains . 
Use 
fine-mesh  snow  chains. They  must  not  add 
more  than  0.53  inch (13.S  mm)  in height,  includ
ing  the  chain  lock. 
You must  remove the  chains when  driving  on 
roads  that  are 
free of snow. When  roads are free 
of  snow,  snow  chains can impair  handling  and .,.

ratio  tires  are  inflated  to  the  specified  pressure 
and  that  the  inflation  pressure is regularly 
checked and  maintained . Tire  pressures should 
be checked at  least  once a  month  and  always
