(D Tips 
If the  capaciti ve passenger  detection  system 
determines  that  the  front  passenger  seat  is 
empty,  the  frontal  airbag  on the  passenger 
side w ill be turned  off, and  the

light w ill stay on. 
Repair,  care and  disposal  of  the  airbags 
Parts  of the  a irbag  system  are  installed  at  many 
d iffe rent  p laces  on your Audi.  Insta lling,  remov
ing, servicing or repa iring a part  in an area  of the 
veh icle can damage  a  part  of an ai rbag  system 
and  prevent  that  system  from  working properly 
in a co llision. 
There are  some  important  thi ngs you have to 
know  to make  sure that  the  effect iveness  of the 
system  w ill not  be impaired  and  that  d isca rded 
components  do not  cause  injury or  pollute  the 
environment. 
A WARNING 
-Improper  care,  servicing and  repair proce
dures  can  increase  the  risk of personal  injury 
and  death  by preventing  an a irbag from  de
ploying when  needed  or deploying an airbag 
unexpectedly: 
- Never cover, obstruct,  or change  the  steer ing wheel  horn  pad or airbag  cover or the  in
strument  pane l or modify them  in any way. 
- Never attach  any objects  such  as cup holders  or te lephone  mountings  to  the  surfaces  cov
ering the  airbag  units. 
- For cleaning the  ho rn pad  or instrument 
panel,  use only a soft,  dry cloth  or one  mois
tened  with  plain water.  So lvents  or cleaners 
c ould  damage  the  a irbag  cover or change 
the  stiffness  o r strength  of the  ma ter ial so 
that  the  airbag  cannot  dep loy and  protect 
properly . 
- Never repa ir, adjust,  or change  any parts  of 
the  a irbag  system. 
- All work on the  stee ring wheel,  inst rument 
panel,  front  seats  or electrical  system  (in 
cluding the  installation  of audio  equipment, 
cellular telephones  and  CB radios,  etc.) 
must  be performed  by a qualified technician 
158 
who has the  training  and  special  equipment  necessary. 
- For any work on the  airbag  system,  we 
strongly  recommend  that  yo u see  your au
thorized  Audi dealer  or qualified  workshop. 
- Never modify the  front  bumper  or  parts  of 
the  vehicle body. 
- Always make sure  that  the  side airbag  can 
inflate  w ithout  interference: 
- Never install  seat  covers or rep lacement 
u pholstery  over the  front  seatbacks  that 
have not  been  specifically approved  by 
A udi. 
- Never use additional  seat  c ushions  that 
cover the  areas  where  the  side a irbags  in
flate. 
- Damage to  the  orig inal seat  cove rs or to 
the  seam  in the  are a of the  side ai rbag 
module  mus t always be repaired  immedi
ate ly by an autho rized Aud i dealer. 
- The a irb ag sys tem  can deploy on ly on ce. Af
ter  an airbag  has  been  deployed,  i t m ust  be 
rep laced  with  new replacement  parts  de
signed  and  approved  especially fo r your A udi 
model version.  Replacement  of complete 
airbag  systems  or a irbag  components  must 
be performed  by qualified workshops  only.

Advanced front  airbag  system  and  children 
Your vehicle  is equipped  wit h a front  "Advanced 
A irbag  System"  i n compliance  w it h  United  States 
F ederal  Motor  Vehicle  Safe ty Standard  ( FMVSS) 
208  as  applicable  at  the  time  your  vehicle  was 
manufactured . 
The  Advanced  Airbag  system  in your  ve hicl e  has 
been  certified  to  mee t the  " low -risk"  requ ire
ments  for  3 -and  6-year  o ld  children  on  the  pas 
senger  side  and  small  adults  on  the  driver  side. 
T he  low  risk deployment  criteria  are  intended  to 
reduce  the  r isk  of  injury  through  interaction  with 
the  airbag  that  can  occur,  for  example,  by being 
too  close  to  the  steering  whee l and  instrument 
panel  when  the  a irbag  inflates . In  add it io n, the 
system  has  been  cert ified  to  comply  with  the 
"suppression"  requiremen ts of  the  Safety  Stand
ar d,  to turn  off  t he front  airbag  for  infa nts  up  to 
12  months  who  are  restra ined  on  the  front  pas
senger  seat  in child  restraints  that  are  listed  i n 
the  Standard. 
E ven  though  yo ur vehicle  is equ ip ped  with  an  Ad
vanced  A irbag  sys tem,  all  children,  especia lly 
those  12  years  and  younger,  should  always  ride  in 
the  back  seat  properly  restrained  for  their  age 
and  size.  The  airbag  on  the  passenger  side  makes 
the  front  seat  a  potent ially  dangerous  p lace  for 
a 
chi ld  to  r ide.  The  fro nt  seat  is  not  the  safes t place 
for  a  child  in  a forward-facing  child  safety  seat . It 
can  be  a very  dangerous  place  for  a n infant  or  a 
l arger  child  in a  rea rward-facing  seat . 
T he  vehicle's  Advanced  Airbag  System  has  a  ca
pacitive  passenger  detect ion  system  in the  front

Steering  recommendation 
The ESC  helps  to  stabilize  the vehicle  by  changing 
the  steering  torque. 
In  vehicles  with  dynam ic steering*,  ESC also 
he lps to  stabilize  the  steering  in  critical  situa
tions. 
Selective wheel  to rque control 
Selective  wheel  torque  control  is used  when  driv
ing  on  curves . The  front  wheel  on  the  inside  of 
the  curve  or  both  wheels  on  the  i nside  of  the 
curv e are  braked  selectively  as  needed . This  al
lows  more  precise  dr iving  in  curves. 
Automatic  post-collision  braking  system 
The  "Automatic  post-collision  braking  system" 
can  help  to reduce  the  risk of  sliding  and  of  other 
collis ions  after  an  accident.  If  the  airbag  control 
module  detects  a coll is ion  above  a  ce rtain  veh icle 
speed,  the  vehicle  is  braked by the  ESC. 
The vehicle  does  not  brake  automatically  if: 
- the  driver  presses  the  acce lerator  pedal,  or 
- the  braking  force  generated  by the  pressed 
brake  pedal  is greater  than  the  braking  force 
that  would  be  initiated  by the  system,  or 
- the  ESC, the  brake  system  or  the  vehicle  electri
ca l system  are  not  functioning. 
Switching  on/off 
Intelligent  Technology 
A WARNING ,-
-The  ESC and  its  integrated  systems  cannot 
overcome  the  limits  posed  by natural  phys i
cal  laws.  This  is especially  important on  slip
pe ry or wet  roads.  If the  systems  begin  act
ing  to stabilize  your  vehicle, you should  im
mediately  alter your  speed  to  match the 
road  and traffic  conditions.  Do not  let  the  in
creased  safety  provided  tempt  you  into tak
ing  risks.  This  could  increase  your  risk of  a 
collis ion. 
- Please  note  the  r isk  of a  collision  increases 
when  driving  fast,  especially  thro ugh  curves 
and  on  slippery  or  wet  roads, and  when  driv
ing  too  close  to  objects  ahead.  The  ESC and  its  integrated  systems  cannot  always  pre
vent  collisions·  there  is still  a  risk  of acc i
dents! 
- Press  the accelerator  pedal  carefully  when 
accelerating  on  even,  slippery  surfaces  such 
as  ice  and snow.  The  drive wheels  can  spin 
even  when  these control  systems  are instal
led  and  this  can  affect  driving  stability  and 
i n crease  the  r isk  of a  coll ision . 
(j) Tips 
-ABS and  ASR only function  correctly  when 
all  four  wheels  are  equipped  with  identical 
tires.  Different  tire  s izes  can  lead  to  a reduc
tion  in engine  power . 
- You  may  hear  noises  when  the systems  de
scribed  are working. 
ESC  turns  on automatically  when you  start  the  engine .

Economical  and  environ
mentally-friendly  driving 
General 
Your personal  style  of  driving  will  determine  the 
economy  of your  vehicle,  as well  as exhaust  and 
noise levels . 
Fuel economy, environmental  impact,  and  wear 
on your engine,  brakes  and t ires  largely depend 
on three  factors: 
-your  personal  dr iv ing style 
- operating  conditions 
198 
- technical  limitat ions 
If you ant ic ipate  what  you need  to  do next and 
drive econom ic a lly, you can easily cut  yo ur fu el 
consump tion by 10-15  percent.  This section  will 
give you some  tips  on how you can he lp the  envi

next,  you w ill need  to  b rake less  and,  thus,  accel
erate  less.  Let the  veh icle coast  whenever  possi

Trailer  mode Driving  with  a  trailer 
General  information 
Your  Audi  was designed  primarily  for  passenger 
transportation . 
If  you  plan to tow  a trailer,  p lease  remember  that 
the  additional  load  will affect  durability, econo
my  and  performance. 
Trailer  towing  not  only  places  more  stress  on  the 
vehicle,  it  also  calls  for more  concentration  from 
the  driver. 
For  this  reason,  always  follow  the  operating  and 
driving  instructions  provided and  use  common 
sense. 
(D Note 
If  you  are  going to  tow  a trai ler,  you  must ac

c::> page  201,  Operating  instructions. 
Technical requirements 
Trailer  hitch 
Use a weight-carrying  hitch  conforming  to  the 
gross  trailer  weight.  The  hitch  must  be  suitable 
for  your  vehicle  and  trailer  and  must be mounted 
securely  on  the  vehicle's  chassis  at  a 
technically 
sound 
location.  Use only  a trailer  hitch  with  a  re
movable  ball  mount.  Always check with  the  trail
e r  hitch  manufacturer  to make  sure  that you  are 
using  the  correct  hitch. 
Do not use a bumper hitch. 
The  hitch  must  be  installed  in such  a way that  it 
does  not  interfere  with  the  impact-absorbing 
bumper  system.  No modifications  should  be 
made  to  the vehicle  exhaust  and  brake systems. 
From  time  to  time,  check  that  all hitch  mounting 
bolts  remain  securely  fastened . 
When  you  are  not  towing  a  trailer, 
remove the 
trailer  hitch ball  mount.  This  prevents  the  hitch 
from  causing  damage  should  your  vehicle be 
struck  from  behind 
c::> &, . 
Trailer  mode 
Trailer  brakes 
If your  trailer  is equipped  with  a brak ing  system, 
check  to be  sure  that  it  conforms  to  all  regula
tions. 
T he  trailer  hydraulic  brake  system must not  be  di
rect ly  connected  to  the  vehicle's  hydraulic  b rake 
system. 
Safety  chains 
Always  use  safety  chains  between  your  veh icle 
and  the  tra iler. 
Trailer  lights 
Trailer  lights must  meet  all  regulations.  Be sure 
to  check  with  your  Aud i dealer  for  correct  wiring, 
switches  and  relays. 
Mirrors 
If you  are  unable to  see  the  traffic  behind  you  us
ing  the  regular  outside  mirrors,  then  you 
must in
stall  extended  mirrors.  It  is  important  that  you 
always have  clear  vision  to  the  rear . 
A WARNING 
--
After removing  the trailer  hitch,  do  not store 
i t  in your  vehicle.  In  case  of  sudden  braking, 
the  hitch  could  fly forward  and  injure you  or 
your  passengers. 
Operating  instructions 
Maximum  trailer  weight 
A  trailer  for  your  vehicle  is limited  to  a typical 
class  1 or  class 2  trailer. 
Trailer  load  distribution 
Be sure  the  load  in the  trailer  is  held securely  in 
place  to  prevent it  from  sh ifting  forward,  back
ward  or  sideways. 
Never  allow a  passenger  to ride  in a trailer c::> &.

A 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. 
Trailer  mode  notes 
Important  to  know 
-
Your vehicle handles  differently  when  towing  a  trailer  because  of the  additional  weight  and  dif
ferent  weight  distribution . Safety,  performance 
and  economy will greatly  depend  on how careful
ly  you load your trailer  and  operate  your rig. 
Before you actually  tow your trailer,  practice 
turning,  stopping  and  backing up  in an  area  away 
from  traffic . Keep practicing  until you have be
come  completely  familiar  with the  way your vehi
cle-trailer  combination  behaves  and  responds. 
Backing up is difficult and  requires  practice.  Back
ing  up with  a  trailer generally  requires  steering 
Trailer  mode 
action  opposite  to  that  when  backing up your ve
hicle without  a trailer. 
Maintain  a greater  distance  between  your vehicle 
and the  one  in front  of you . You will need  more 
room  to  stop.  To compensate  for the  trailer, you 
will need  a  larger than  normal  turning  radius. 
When  passing,  remember  that  you  cannot  accel
erate  as  fast  as you  normally would  because  of 
the  added  load. Make sure  you have enough  room 
to  pass.  After passing,  allow plenty  of room for 
your trailer  before  changing  lanes again. 
Avoid jerky starts,  sharp  turns or rapid  lane 
changes. 
(D Tips 
- Do not  tow a trailer  during  the  break-in  peri
od of your vehicle. 
- If you  tow  a trailer,  your Audi  may require 
more  frequent  maintenance  due  to  the  ex
tra  load 
c::> page  2 7 4. 
Parking on a slope 
Do  not  park  on a slope  with  a trailer.  If it cannot 
be  avoided,  do so  only after  doing  the following: 
When  parking: 
" Apply  the  foot  brake. 
"  Have someone  place chocks under  both  the ve
hicle and  the  trailer  wheels. 
"With  chocks  in place,  slowly  release the brakes 
until  the  wheel  chocks absorb the load. 
"Turn  the  wheels  towards  the  curb. 
...  Apply the  parking brake. 
"Select  the  P selector  lever position. 
When  restarting  after  parking: 
"Apply  the  foot  brake. 
"Start  the  engine. 
"Select  the D/S  selector  lever position. 
"Release  the  parking  brake and  slowly pull out 
and  away from  the  wheel  chocks. 
"Stop  and  have someone  retrieve  the  wheel 
chocks .

Cooling  system 
Coolant 
T he  engine  coolant  performs  two  functions:  it 
keeps  the  engine  from  overheating  and  it pro 
tects  the  engine  from  freezing  in the  winter . 
The cooling sys tem  is sealed  and  generally  re
qu ires  little  attention . 
T he cooling system  has  been  filled at  the  facto ry 
with a permanent  coo lant  wh ich does  not  need  to

tion  of  coolant  additive  must  be  at  least  50 % 
but  not  more  than  60 % 
to  maintain  antifreeze 
protection  and  cooling efficiency . 
If the  coolant 
frost  protection  is too  low, the  coolant  could 
freeze  and  damage  the  ve hicle heati ng and  en
g ine cooling system . 
For year-round  driving, antifreeze  is added  at  the

Before  you  check  anything  in  the engine  compart
ment, 
always  read and heed  all WARNINGS 
¢ A in Working  in the  engine  comportment  on 
page  218. 
.,.  Read  the  brake  fluid level from  the  brake  fluid 
reservoir 
¢ fig.  192,  ¢page  220,  fig.  188. The 
brake  fluid  leve l must  be  between  the "MIN" 
and  "MAX"  markings . 
The  location  of the  brake  f luid reservo ir can  be 
seen  in  the engine  compartment  illustration 
¢page  220. 
The  fl uid level  may  drop slightly after  some  time 
due  to  the automatic  adjustment  of  the  brake 
pads.  This is  not  cause  for  alarm. 
I f the  brake  fluid  level  falls 
considerably below 
the  "MIN"  mark,  the  brake warning/indicator 
light 
1111 (U .S. models)/ . (Canadian  models) 
will  come  on ¢ 
page  14. Do not  cont inue  to  oper
ate  the  vehicle . The  complete  brake  system 
should  be  thoroughly  checked  by an  authorized 
Audi  dealer  or  other  qualified  facility  and  the  cause  corrected.  If  the  brake  fluid  level  is too  low, 
the  brake  warning/indicator  light  will  illuminate. 
Contact  an  authorized  Audi dealer 
immediately . 
Changing  brake  fluid 
Hove the  broke fluid  changed  by on experienced 
technician . 
Brake  fluid  absorbs  moisture  from  the  air. If the 
water  content  in the  brake  fluid  is too  high,  cor-
Checking  and Filling 
rosion  in the  brake system  may  result  after  a  peri
od  of  time.  The  boiling point  of  the  brake  fluid 
will  also  decrease  considerably  and  decrease  braking  performance . 
T herefore,  the  brake  fluid must  be  changed 
every 
two  years. 
Always  use  new  brake  fluid  which  con
forms  to  Federal  Motor  Vehicle  Standard  "FMVSS 
116  DOT 4". 
The  brake  fluid  reservoir  can  be  difficult  to  reach, 
therefore,  we  recommend  that  you  have  the  brake  flu id  changed  by your  authorized 
Audi 
dealer . 
Your dea ler  has  the  correct  tools,  the 
right  brake  fluid  and  the  know-how  to  do  this  for 
you . 
_&. WARNING 
-. 
- Brake  fluid  is  poisonous . It  must  be  stored 
only  in the  closed  original  conta iner  out  of 
the  reach  of  children! 
- Brake  failure  can  resu lt  from  o ld  or  inappro
p riate  brake  fluid.  Observe  these  precau
tions: 
- Use  only  brake  fluid  that  meets  SAE speci
fication 
J 1703 and  conforms  to  Federa l 
Motor  Vehicle  Standard  116.  Always  check 
with  your  authorized  Audi dealer  to  make 
sure  you  are  using  the  correct  brake  fluid . 
The  correct  type  of brake  flu id  is  also  ind i
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. 
T his  can  seriously  affect  the  efficiency  of 
the  brakes  as  well  as  your  safety.  This 
could  result  in  an  accident.

@ For the  sake of  the  environment 
Because  of  the  problem  of  prope r disposal  of 
brake  fluid  as  well  as the  special  tools  re
quired  and  the  necessary  expertise,  we  rec
ommend  that  you  have  the  brake  flu id
