A WARNING 
-When  adding  oil,  do  not  let  oi l dr ip onto  hot 
e ngine  components.  This  increases  the  risk 
of  afire. 
- You must  seal  the  cap  on  the  oil filler  open

onto  the  hot  engine  and  exhaust  system 
when  the  engine  is  runn ing,  be ca use  this  is 
a fire  hazard. 
- Always  clean  sk in thoro ughly  if it  comes  into

dea ler  or  authorized  Audi Service  Facility  to 
have  excess  engine  oil  extracted  if necessa
ry. 
-Do not  mix  any  ad ditiona l lubricants  into 
the  engine  oil.  Damage  caused  by such  add i
tives  is  not  covered  by the  warranty  . 
@ For the  sake of  the  environment

system  the  next  time  the ignition  is 
switched  on. 
- The  engine  oil  consumption  may  be  up to 
0.5  quart/600  miles  (0.5  liter/1 ,000  km), 
depending  on  driving  style  and  operating 
conditions . Consumption  may  be  higher 
during  the  first  3,000  miles  (5,000  km).  Be
cause  of  this,  the  engine  oil  level must  be 
checked  regularly . 
It would  be  best  to  check 
each  time  you  refuel  your  vehicle  and  before 
long  drives . 
Changing the  engine  oil 
We recommend  that  have your  oil changed  by an 
authorized  Audi dealer or a qualified  service sta
tion. 
Before  you  check  anything  in the  engine  compart 
ment , 
always  read  and  heed  all  WARNINGS q .&. 
in Working in the  engine compartment  on 
page  198. 
The  engine  oil  must  be  changed  according  to  the 
intervals  specified  in your  Warranty 
& Mainte
nance  booklet.  This  is very  important  because  the 
lubricating  properties  of  oil diminish  gradually 
during  normal  vehicle  use. 
Under  some  circumstances  the  engine  oil  should 
be  changed  more  frequently . Change  oil  more  of
ten  if you  drive  mostly  short  distances , operate 
the  vehicle  in dusty  areas  or  under  predominantly 
stop-and-go  traffic  conditions,  or  have  your  vehi
cle  where  temperatures  remain  below  freezing 
for  extended  periods. 
Detergent  additives  in the  oil will  make  fresh  oil 
look  dark  after  the  engine  has  been  running  for a 
short  time.  This is  normal  and  is not  a  reason  to 
chang e the  oil  more  often  than  recommended. 
Because  of  the  problem  of  proper  disposal,  along 
with  the  special  tools  and  necessary  expertise  re
quired,  we  strongly  recommend  that  you  have 
your  oil changed  by an  authorized 
Audi  dealer or 
a  qualified  service  station . 
If you  choose  to  change your oil  yourself, please 
note  the  following  important  information: 
204 
A WARNING 
-
To  reduce  the  risk  of  personal  injury  if you 
must  change  the  engine  oil  in your  vehicle 
yourself: 
- Wear  eye  protection. 
- To reduce  the  risk  of  burns  from  hot engine 
-
oil, let the  engine  cool  down  to  the  touch . 
- When  removing  the  oil drain  plug  with  your 
fingers,  stay  as  far  away  as  possible.  Always  keep  your  forearm  parallel  to  the  ground  to 
help  prevent  hot  oil from  running  down  your 
arm . 
- Drain  the  oil  into a  container  designed  for 
this  purpose,  one  large enough  to hold  at 
least  the  total amount  of  oil  in your  engine. 
- Engine  oil  is  poisonous . Keep  it  well  out  of 
the  reach  of  children. 
- Continuous  contact  with  used  engine  oil is 
harmful  to your  skin . Always  protect  your 
skin  by washing  oil  off  thoroughly  with  soap 
and  water. 
(D Note 
Never  mix  oil additives  with  your  engine  oil. 
These  additives  can  damage  your  engine  and 
adversely  affect  your  Audi  Limited  New Vehi
cle  Warranty. 
@ For the  sake of  the  environment 
- Before  changing  your  oil,  first  make  sure  you  know  where  you  can  properly dispose  of 
the  used  oil. 
- Always  dispose  of  used  engine  oil  properly . 
Do  not  dump  it  on  garden  soil,  wooded 
areas,  into  open  streams  or  down sewage 
drains. 
- Recycle  used  engine  oil  by taking  it to  a  used 
engine  oil  collection  facility  in your  area,  or 
contact  a  service  station .

Checking  and  Filling 
_& 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  additive  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. 
CD 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.  See  an  authorized  Audi deal
er  or  authorized  Audi Service  Facility for  assis
tance .

towing 
CD Note 
Veh icles  with  an  automatic  transmission  can
not  be started  by pushing  or  towing. 
Starting  with  jumper 
cables 
If necessary,  the  engine can be started  by con
necting  it to  the  battery  of  another  vehicle. 
If the  engine  shou ld  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 jumpe r cables to  start  the  engine. 
Jumper  cables 
Use only jumper  cables  of  suffic iently  large cross 
section 
to  carry  the  starter  current  safely.  Refer 
to  the  manufacturer's  specifications. 
Use only jumper  cables  with 
insulated term inal 
clamps  which  are  dis tinct ly marked: 
plus (+)  cable in  most  cases  colored re d 
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  avo id  leaning

- Veh icle  batteries  generate  explosive  gases. 
Keep  sparks,  flame  and  lighted  cigarettes 
away  from  batter ies. 
- 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  rat ing . The  capacity  (Ah) of 
the  booster  battery should  not  be  lower 
than  that of the  discharged  battery.  Use of 
batter ies  of  different  voltage  or  substantial
ly different  "Ah"  rating  may  cause  an exp lo
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 . T he  battery  case  may have  be  weak
ened. 
- Use  of  batteries  of  different  voltage  or  sub
stantially  different  capacity  (Ah) rating  may 
cause  an  exp losion  and  injury . The  capacity 
(Ah) of  the  booster  battery  should  not  be
