Check ing  and  F illing 
Using the  proper  engine  oil is impo rtant  for the 
functionality  and  service life of the  engine.  Your  engine  was facto ry-filled with a  h igh-quality  oi l 
which can usually  be  used  throughout  the  entire 
year. 
@) Note 
Your Limited New Vehicle War ranty does  not 
cover damage  or  malfunctions  due  to  failure 
to follow  recommended  maintenance  and  use 
requirements  as  set  forth  in the  Audi Owner's 
Manual and  Warran ty 
& Maintenance  booklet. 
- Use only a high quality  eng ine oil t hat  ex-
p ressly complies  with  the  Audi oil qua lity 
standard  specified for your vehicle's  engine . 
Using a ny o ther  oil can cause  serious  engine 
d am age. 
- D o not  mix any lubricants  o r other  addit ives 
i nto  the  engine  oil.  Doing so ca n cause  en
g ine damage. 
(D Tips

Engine  oil  consumption 
The engine  in your  vehicle  depends  on  an  ade
quate  amoun t of  oil  to  lubricate  and  cool  all  of 
its  moving  parts . 
In order  to  provide effective  lubr ication  and  coo l
ing of in ternal  engine  components,  all internal 
combustion  eng ines consume  a certain  amou nt 
of oil. Oil co nsumption  varies from  engine  to en
g ine and  may change  significant ly over the  life of 
206 
th e engine.  Typically, engines  w ith  a specified 
break-in  period  (see 
r=:> poge  185) consume  more 
o il  dur ing the  b reak-in per iod than  they  consume 
after  oil consumption  has  stabili zed . 
U nder  normal  cond itions,  the  rate  of oil con 
sumption  depends  on the  q ua lity and viscosity of 
the  oil, the  RPM (revo lutions  per  m inute)  at 
which the  engine  is operated,  the  ambient  tem perature  and  road  condit ions.  Further  factors  are 
the  amo unt  of o il di lution  from  water  condensa 
t ion or fuel  residue  a nd the  oxidation  level of  the 
o il.  As any engine  is subject  to  wea r as  mileage 
builds  up,  the  o il cons umption  may increase  ove r 
t i me  unt il repla ce m ent  of wo rn components  m ay 
be come  necessary . 
With  a ll these  va riab les  coming  into  p lay, no 
sta ndard  rate  of o il cons umption  can  be estab
li sh ed or spec ified . T he re  is no alte rn ative  to reg
ul ar and  frequen t checking of the  oi l level, see 
Note .

er's  g lycol-bas edcoo lant  additive  Gl3  antifreeze 
with  anticorrosion  additives  (50%  for  USA mod
e ls;  60%  for  Canadian  models).  This m ixture 
both  assures  the  necessary  frost  protection  and 
protects  metal  components  in the  engine's  cool
ing system  from  corrosion  and  scaling. 
It also 
raises  the  boiling  point  of the  coolant . 
Do not  reduce  the  concentration  of  the  coolant  in 
the  summer  by adding  p lain  water . 
The propor
tion  of  coolant  addit ive must be  at  l eas t 50° /4 
but  not  more  th an 60 % 
to  maintain  antifreeze 
p rotection  and  cooling  effic iency. If the  coolant 
frost  protec tion  is too  low, the  coolant  co uld 
freeze  and  damage  the  vehicle  heating  and  en
gine  cooling  system. 
F or yea r-round  driving,  antifreeze  is added  at  the 
factory  for  temperatures  down  to : 
- -31  °F (- 35  °C) USA 
- -40  °F ( - 40  °C) Canada. 
If you must  add  coolant,  use  a  mixture  of water 
and  coolant  addit ive.  Mixing the  coolant  additive 
with  d istilled  water  is  recommended.

(D Note 
- Before winter  sets  in,  have the  coolant 
checked  to  see  if the  coolant  additive  in your 
vehicle  is sufficient  to  meet  the  climate  con
dit ions.  This is especially  important  if you 
li ve in a reg ion where  the  w inte r is ext reme
l y co ld.  If  ne cessary,  in cre ase  the  proport io n 
of  coo lant  add itive  to  60%. 
- When  addi ng coolant  addit ive to  you r cool
i ng system,  remember: 
- We  recommend  using  only coolant  addi
tive  Gl2 ++ or  Gl3  for your ve hicle. T his 
coolant  additive  is available  at  authorized 
Audi dea lers.  Othe r types  of  antifreeze  can 
significant ly reduce  cor ros ion  p rotection  . 
Ch eck ing  and  Filling 
The resulting  co rrosion  can cause  a loss  of 
coolant  and  serious  engine  damage. 
- Do not  add  any type  of  radiator  lea k sealant 
to  your vehicle's  engine  coolant.  Adding  ra
diator  repair  fluid  may  adversely  affect  the 
function  and  performance  of your  cooling 
system  and  cou ld resu lt  in damage  not  cov

-To avoid  being  burned,  do  not  spill  anti
freeze  or  coolant  on  the  exhaust  system  or  hot  engine  parts.  Under  certain  condi
tions,  the  ethylene  glycol  in  engine  cool ant  can  catch  fire. 
- Antifreeze  is  poisonous.  Always  store  anti
freeze  in  its original  container  and  well  out 
of  the  reach  of  children. 
- If you  drain  the  coolant,  it  must  be  caught 
and  safely  stored  in a  proper  container 
clearly  marked  "poison". 
(D Note 
-Do not  add  coolant  if the  expansion  tank  is 
empty . Air could  enter  the  cooling  system 
and  damage  the  engine.  If this  is the  case, 
do  not  continue  driving.  Seek  professional 
assistance. 
- Coolant  pollutes  the  environment  and  could 
cause  an  engine  fire.  Excess coolant  will  be 
forced  out  through  the pressure  relief valve 
in  the  cap  when  the  engine  becomes  hot. 
- If,  in an  emergency,  only  water  can  be  add
ed,  the  correct  ratio  between  water  and  an
tifreeze 
c::> page  208 must  be  restored  as 
soon  as  possible. 
@) For the  sake of the  environment 
Drained  coolant  should  not  be reused.  Always 
dispose  of  used coolant  while  observing  all 
environmental  regulations. 
Radiator  fan 
The radiator  fan  switches  on  automatically  by it
self. 
The  radiator  fan is driven  by the  engine  via the  V
belt . The  viscous  clutch  regulates  the speed  of 
the  fan  according  to  the  temperature of  the  cool
ant. 
An auxiliary  electric  radiator fan*  switches  on  and 
off  depending  on  coolant temperature  and  other 
vehicle  operating  conditions. 
After  you  switch  the  engine  off,  the  auxiliary  fan 
can  continue  running for up to  10  minutes  -even 
Checking  and  Filling 
with  the  ignition  off.  It can  even  switch  on  again 
later  by itself 
c::> & , if 
- the  temperature  of  the  engine  coolant  rises due 
to  the  heat  build-up from the engine  in  the en
gine  compartment,  or 
- the  engine  compartment  heats  up because  the 
vehicle  is  parked in  intense  sunlight. 
A WARNING 
-To reduce  the  risk  of  personal  injury never 
touch  the  radiator  fan. 
- The  auxiliary  electric  fan  is temperature 
controlled  and  can  switch  on  suddenly  even 
when  the  engine  is  not  running. 
- The  auxiliary  radiator  fan  switches  on  auto
matically  when  the  engine  coolant  reaches  a 
certain  temperature  and  will  continue  to  run 
until  the  coolant  temperature  drops.

Changing  brake  fluid 
Have the  brake  fluid  changed  by an experienced 
technician . 
Brake  fluid  absorbs  mo isture  from  the  air.  If  the 
water  content  in the  b rake  fluid  is too  high,  cor
rosion  in  the  brake  system  may  resu lt  afte r ape 
riod  of  t ime.  The  boiling  poi nt  of  the  brake  flu id 
will  also  decrease  cons iderably  and  decrease 
b raking  perfo rman ce. 
Therefore,  the  brake  fluid  must  be  changed 
every 
two year s. 
Always  use  new  brake  fluid  wh ic h  con
forms  to  Fede ral  Motor  Veh icle  Standard  "FMVSS 
1 16  DO T 4". 
The  brake  fluid  reservoir  can  be  diff icult  to  reach, 
therefore,  we  recommend  that  yo u have  the

Emergency  situations 
Emergency  situations 
General 
This chapter  is intended  for  trained  emergency  crews and  working  personnel  who  have the  nec
essary tools  and  equipment  to  perform  these 
operations. 
Starting  by  pushing  or 
towing 
CD Note 
Vehicles  with  an  automatic  transmission 
cannot  be started  by pushing  or towing. 
Starting  with  jumper 
cables 
If necessary,  the  engine con be started  by  con
necting  it to  the  battery  of  another  vehicle. 
If the  engine  should  fail  to start  because  of a  dis
charged  or weak  battery,  the battery  can  be  con
nected  to  the  battery  of 
another vehicle,  using a 
pair  of jumper  cables to  start  the  engine. 
Jumper  cables 
Use only jumper  cables  of  sufficiently largecross 
section 
to  carry  the  starter  current  safely.  Refer 
to  the  manufacturer's  specifications. 
Use only jumper  cables  with 
insulated terminal 
clamps  which  are distinctly  marked : 
plus(+)  cable in most  cases  colored red 
minus(-)  cable 
in  most  cases colored black. 
A WARNING 
Batteries  contain  electricity,  acid,  and  gas. 
Any of these  can  cause  very  serious  or fatal  in
jury.  Follow  the  instructions  below  for 
safe 
handling  of your  vehicle's  battery. 
-Always  shield  your  eyes  and  avoid  leaning 
over  the  battery  whenever  possible. 
-A  discharged  battery  can  freeze  at  tempera
tures  just below  32  °F (0 °C).  Before  con
necting  a jumper  cable,  you  must  thaw  the 
250 
frozen  battery  completely,  otherwise  it  could  explode. 
- Do not  allow  battery acid  to  contact  eyes  or 
skin.  Flush  any  contacted  area  with  water  immediately. 
- Improper  use  of a  booster  battery  to  start  a 
vehicle  may  cause  an  explosion. 
- Vehicle  batteries  generate  explosive  gases. 
Keep  sparks,  flame  and  lighted  cigarettes 
away  from  batteries. 
- Do not  try  to  jump  start  any  vehicle  with  a 
low acid  level  in the  battery. 
- The voltage  of the  booster  battery  must  also 
have  a  12-Volt  rating.  The  capacity  (Ah) of 
the  booster  battery  should  not  be  lower 
than  that  of the  discharged  battery. Use of 
batteries  of  different  voltage  or  substantial
ly different  "Ah" rating  may  cause  an  explo
sion  and  personal  injury. 
- Never  charge  a frozen  battery.  Gas trapped  in  the  ice  may  cause  an  explosion. 
- Never  charge  or  use a  battery  that  has been 
frozen . The  battery 
case may  have  be  weak
ened . 
- Use of  batteries  of  different  voltage  or  sub
stantially  different  capacity  (Ah)  rating may 
cause  an  explosion  and  injury.  The  capacity 
(Ah) of  the booster  battery  should  not be 
lower  than  that  of  the discharged  battery. 
- Before  you check  anything  in the  engine 
compartment,  always  read  and  heed all 
WARNINGS 
~page  203. 
CD Note 
-Applying  a  higher  voltage  booster  battery 
will  cause  expensive  damage  to sensitive 
electronic  components,  such  as  control 
units,  relays,  radio,  etc. 
- There  must  be  no  electrical contact between 
the  vehicles  as otherwise  current  could  al
ready  start  to flow  as soon  as  the  positive 
(+) terminals  are  connected. 
@ Tips 
The  discharged  battery must be  properly  con-
nected  to  the  vehicle's  electrical  system.  .,..
