Using the  proper  engine oil is important  for the 
functionality  and service life of the  engine.  Your 
engine  was factory-filled  with  a high-quality  oil 
which  can usually  be  used  throughout the  entire 
year . 
Q) Note 
Your Limited New Vehicle Warranty  does  not 
cover damage  or malfunctions  due  to  failure 
to follow  recommended  maintenance  and  use 
requirements  as  set  fo rth  in the  Audi Owner's 
Manual and  Wa rranty 
& Maintenance  booklet. 
- Use only a high qua lity eng ine oi l th at  ex-
pressly complies  with  the  Audi oil qua lity 
stan dard specified for your vehi cle's  engine. 
Using any o ther  oil can cause  serious  engine 
damage . 
- Do not  mix any lubricants  o r other  addit ives 
i nto  the  engine  oil.  Doing so can cause  en
gine  damage. 
(D Tips 
I f you nee d to  add  oi l and there  is none  availa
ble that  meets  the Audi o il qu ality st andard 
your  engine  requires,  you may ad d a total  of 
no more  than  0 .5 quart/liter  of a high-quality 
"synthet ic"oil that  meets  the  following speci
fications. 
- ACEA A3 o r API SM with a viscosity g rade  of 
SAE OW-30, SAE 5W-30  or SAE  5W-40. 
- For more  information  about  engine  oi l that 
has  been  approved  for your vehicle, please

Engine  oil  consumption 
The engine  in your  vehicle  depends  on  an  ade
quate  amount  of  oil  to lubricate  and  cool  all  of 
its  moving  parts . 
In order  to  provide effective  lubrication  and  cool
ing  of internal  engine components,  all internal 
180 
combust ion  engines  consume  a certa in amo unt 
of oil. Oil consumption  varies from engine  to  en
gine and  may change  significantly  over  the life of 
the  engine.  Typically, engines  w ith  a specified 
break-in  period  (see 
c:::;, page  159) consume  more 
o il  dur ing the  break-in  per iod  than  they consume 
af ter o il  consumption  has  stab ilized . 
Under normal  conditions,  the  rate of oil  con
sumption  depends  on the  quality  and viscos ity  of 
the  oil,  the RPM (revo lutions  per  m inute)  at 
wh ich  the engine  is operated,  the  amb ient  tem
perature  and  road  condit ions.  Further  factors a re 
the  amount  of o il di lution  from  wate r co ndensa
tion  or fue l resid ue  an d the  oxidation  level of  the 
o il.  As any engine  is sub ject  to  wear  as  mileage 
builds  up, the  oi l cons umption  may  increase over 
time  unt il replacement  of worn  components  may 
become  necessary. 
With  a ll these  variab les  coming  into  p lay, no 
standard  rate  of oil consumption  can be  estab
li shed  or specified.  The re  is no  alternative  to reg
u lar  and  frequent  checking of the  oi l level,  see 
Note. 
If the  yellow engine  oil level warning  symbo l Ell 
in the  instrument  cluster  lights  up, you sho uld 
check  the  oil level  as  soon  as  possible 
c:::;, page  181. Top  off the  oil  at  your earliest  con
venience

(D Note 
Driving w ith  an  insuffic ient  oil level is likely to 
cause  severe  damage  to  the  eng ine. 
(D Tips 
- The oil  pressure  warn ing d isplay.  is  not 
an indicator  of  the  oil  level.  Do not  rely  on 
it.  Instead,  check the  oil  level  in your en
g ine  at  regular int ervals , pr eferably  each 
time  you  refuel,  and alway s before  going 
on a long  trip .

Cooling  system 
Coolant 
The engine  coolant  performs  two  functions:  it 
keeps  the  engine  from  overheating  and  it pro 
tects  the  engine  from  freezing  in the  winter . 
The  cooling  system  is sealed  and  generally  re
quires  little  attention. 
T he  cooling  system  has  been  filled  at  the  factory 
with  a  permanent  coolant  which  does  not  need  to 
be  changed . The  coolant  consists  of  a  mixture  of 
specially  condit ioned  water  and  the  manufactur 
er's  glycol-basedcoolant  add itive  G 13  antifreeze 
with  anticorrosion  additives  (SO% for  USA mod
e ls;  60%  for  Canada  models) . This  mixt ure  bot h 
assures  the  necessary  frost  protec tion  and  pro
tects  meta l components  in the  engine's  cooling 
system  from  corrosion  and  scaling . It  also  raises 
the  boiling  point  of  the  coolant. 
D o  not  red uce  the  concent ration  of  the  coolant  in 
the  summer  by  add ing  p la in water. 
The propor
tion  of  coolant  addit ive  mu st  be at  least  50 % 
but  not  more than  60 % 
to  mainta in  antifreeze 
protection  and  cooling  efficiency.  If  the  coolant 
frost  protection  is  too  low,  the  coolant  could 
freeze  and  damage  the  vehicle  heating  and  en
g ine  cooling  system . 
For year-round  driving,  antifree ze  is added  at  the 
factory  for  temperatures  down  to : 
- -31° F(- 3S°C)USA 
- -4 0  ° F ( - 40  °C) Can ada. 
If you  must  add  coolant,  use  a  m ixture  of  water 
and  coolant  addit ive.  M ixing  the  coolant  additive 
with  d istilled  water  is recommended .

(D Note 
-Befo re winter  se ts  in,  have  the  coo lant 
checked  to  see  if the  coolant  additive  in you r 
vehicle  is sufficient  to  meet  the  cl imate  con -
Check ing  and  Filling 
ditions.  This  is especially  important  if you 
live  in a  region  where  the  winter  is extreme
ly cold.  If  necessary,  increase  the  proportion 
of  coolant  additive  to  60%. 
- When  adding  coolant  additive  to  your  cool
ing  system,  remember : 
- We  recommend  us ing  only  coolant  add i
tive  G12+ + or  G13  fo r yo ur  vehicle.  This 
coolant  addit ive  is avai lab le  a t aut horized 
A udi  dealers . O ther  types  of  antifree ze  can 
significantly  reduce  corrosion  pro tect ion . 
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  ra 
diator  repair  fluid  may  adversely  affect  the 
function  and  performance  of  your  cooling  system  and  cou ld  resu lt  in damage  not  cov

Coolant  loss 
Coolant loss  may  indicate  a leak in  the  cooling 
system.  I n the  event  of  coolant  loss,  the  cooling 
system  should  be  inspected  immediately  by your 
author ized  Audi  dealer.  It  is  not  enough  me rely 
to  add  coolant. 
I n a 
se aled system,  losses  can  occur  only  if the 
boi ling  point  of  the  coo lant  is ex ceeded  as  a  re 
sul t of  over heat ing. 
A WARNING 
T he  cooling  system  is unde r pressure  and  can 
get  very  hot . Red uce  the  risk  of  scalding  from 
hot  coolant  by following  these  steps. 
- Turn  off  the  eng ine  and  a llow  it to  cool 
down . 
- Protect  your  face,  hands  and  arms  from  es 
caping  fluid  and  steam  by  cove ring  the  ca p

Before  you  check  anything  in the  engine  compart
ment, 
always  read  and  heed all  WARNINGS 
¢ A in Working  in  the engine  compartment  on 
page  177. 
., Read  the  brake  fluid  level  from  the  brake  fluid 
reservoir 
<=> fig . 153,  ¢page  179,  fig . 149 . The 
brake  fluid  level  must  be  between  the 
" MIN" 
and  "MAX " markings. 
The  brake  fluid  reservoir  is  located at  the  rear 
partition  of  the engine  compartment  on  the  left 
side ¢ 
page  179 . 
The  fluid level may drop slightly after  some  time 
due  to  the  automatic  adjustment  of  the  brake 
pads . This  is not  cause  for alarm . 
If  the  brake  fluid  level falls 
considerably below 
the  ' 'MIN"  mark,  the  brake warning/indicator 
light  (USA models: 
1111 , Canada  models:. ) 
will  come  on¢

Changing  brake  fluid 
Have the  brake  fluid  changed  by an  experienced 
technician . 
Brake  fluid  absorbs  moisture  from  the  air. If the 
water  content  in the  brake  fluid  is too  high,  cor
rosion  in the  brake  system  may  result  after  ape
riod  of  time . The  boiling  po int  of  the  brake  fluid 
will  a lso  decrease  considerably  and  decrease 
braking  performance. 
Therefore , the  brake  fluid  must  be  changed 
every 
two  years . 
Always use new  brake  fluid  which  con
forms  to  Feder-al Motor  Vehicle  Standard  "FMVSS 
116  DOT 4 ". 
The  brake  fluid  reservoir  can  be  difficult  to  reach , 
therefore,  we  recommend that  you  have  the 
brake  fluid  changed by your  author ized 
Audi 
dealer . 
Your  dealer  has  the  correct  tools, the 
right  brake  fluid  and  the  know-how  to do  this  for 
you. 
A WARNING 
- Brake  fluid  is  poisonous. It  must be stored 
only  in the  closed  original  container  out  of 
the  reach  of  children! 
- Brake  fai lure  can  result  from  o ld  or  inappro
priate  brake fluid. Observe  these  precau
tions: 
- Use  only brake  fluid  that  meets  SAE  speci
fi cation 
J 1703  and  conforms  to  Federal 
Motor  Veh icle Standard  116.  Always check 
with  your  authorized  Audi  dealer  to make 
sure  you  are  using the  correct  brake fluid . 
The  correct  type  of  brake  f luid is  also  indi
cated  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  long . 
This  can  seriously  affect  the  efficiency  of 
the  brakes  as  well  as  your  safety.  This 
could  result  in an  accident.

Battery 
General  information 
Under normal operating  conditions,  the  battery 
in your  Audi  does  not  need  any  maintenance. 
With 
high outside  temperatures  or  long  daily 
drives  we  recommend  that  you  have  the  electro
lyte  level  checked  by an  authorized  Audi  dealer  or 
qualified  workshop.  The electrolyte  level should 
also  be  checked  each  time  the battery is charged 
c> page  189. 
Have  the  battery  checked  when  you take  your  ve
hicle  in for  serv ice.  You are  well  advised  to re
place  a  battery  t hat  is older  than  5 years. 
With  certain  types  of airbag  deployment,  the  battery  is disconnected  from  the  vehicle  electri
cal  system  for  safety  reasons 
c> & in Repair,  care 
and  disposal  of  the  airbags  on page  125 . 
Disconnecting  the  battery  terminals 
Some  vehicle functions (power  window  regula
tors,  for  example)  are  lost  if the  battery  termi nals  are  disconnected.  These  functions  have  to  be 
relearned  after  the  battery  terminals  are  con
nected  again.  To prevent  th is,  the  battery  should 
only  be  disconnected  from  the  vehicle  e lectr ica l 
system  when  abso lutely  necessary  for  repairs. 
Vehicles  not  driven  for  long  periods 
If  you  do  not  drive  your  vehicle  over  a  period  of 
several  days  or weeks,  electrical  components  are 
gradually  cut back  or  sw itched  off.  This  reduces 
energy  consumption  and  maintains starting ca
pability  over  a longer  pe riod 
c> page  157. 
Some  of the  conven ience  functions  may  not  oper
ate,  such  as  the  interior  lights  or  the  power  seat 
adjustment.  The  convenience  functions  will  be 
available  again  when  you turn on the  ignition  and 
start  the engine. 
Checking  and Filling 
Winter  operation 
During  the  winter months,  battery capacity  tends 
to  decrease  as  temperatures  drop . This  is be
cause  more  power  is also  consumed  while  start
ing,  and  the  headlights,  rear  window  defogger, 
etc.,  are  used  more  often. 
Avo id  unnecessary  power  consumption,  particu
larly  in  city traffic  or  when traveling  only  short 
distances . Let  your  authorized  Audi  dealer  check 
the  capacity  of the  vehicle  battery  before  winter 
sets  in 
c> page  189. A well  charged  battery  will 
not  only  prevent starting  problems  when  the 
weather  is  cold,  but  will also  last  longer . 
(D Tips 
If  your  vehicle  is  left  standing  for  several 
weeks  at  extremely  low temperatures,  the  ve
hicle  battery  should  be  removed and  stored 
where  it  w ill not  freeze.  This will  prevent  it 
from  be ing damaged  and  having  to  be re
placed. 
Working  on  the  battery 
Be  especially  careful  when  working  on  or near 
the  battery.

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 
(D Note 
Vehicles  with  an  automatic  transmission 
cannot  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  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  large cross 
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 
Emergency  situations 
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 
r::!)page  177. 
(D 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. 
(D Tips 
- The  discharged  battery must  be  properly 
connected  to  the  vehicle's  electrical  system.  ..,.
