Important  safety  instructions  on 
monitoring  the  Advanced Airbag  System 
A WARNING 
An airbag  system  that  is not  functioning 
properly  cannot  provide  supplemental  pro
tection  in  a frontal  crash. 
- If the  airbag  indicator  light  comes on,  it 
means that  there  may be someth ing 
wrong  with  the  Advanced Airbag  System . 
It  is possible that  the  airbag  will  inflate 
when  it  is not  supposed  to,  or w ill  not  in 
flate  when  it  should . 
- Have the  airbag  system  inspected  imme
diately  by your  author ized Audi  dealer . 
A WARNING 
If  the  front  airbag  inflates,  a ch ild without 
a child  restra int,  or  in  a rearward-fac ing 
child  safety  seat,  or  in a forward-facing 
child  restraint  that  has not  been prope rly 
installed  will  be serio usly injured  and can 
be killed. 
- E ven though  your  veh icle is equipped 
with  an Advanced Airbag  System , make 
certain  that  a ll children,  especially  12 
years and younger,  a lways ride on the 
back seat  properly  restrained  for  their 
age and si ze. 
- Always  install  forward  or  rea r-facing 
child  safety  seats on the  rear seat  -even 
with  an Advanced Airbag  System. 
- If you  must  install  a rearward-facing 
child  safety  seat  on the  front  passenger 
seat  because of  exceptional  circumstan
ces and the 
PAS SENG ER AIR  BAG OFF 
light  does not  appear  and stay on,  imme
diately  install  the  rear-fac ing ch ild  safety 
sea t in a rear seating  position  and  have 
the  a irbag  sys tem inspected  by you r au
tho rized Aud i dea ler. 
-
A irbag  system  135 
-A t ight  tether  or  other  strap  on a rea r
ward-facing  child  rest raint  attached  to 
the  front  passenger seat  can put  too  much  pressure on the  weight-sensing 
mat  in the  seat  and reg iste r more  weight 
than  is actually  on the  seat . The heavie r 
weight  registered  can make the  system 
wo rk as  tho ugh an adult  we re on  the seat 
and deploy  the Advanced Airbag  when  it 
m ust  be suppressed causing  serious  or 
even fata l injury  to  the  chi ld . 
- If , in exceptiona l c ircumstances , you 
m ust  install  a forward-facing  child  re
straint  on the  front  passenger seat,  al
ways move the  seat  into  its  rearmost  po sition  in the  seat's fore  and aft  adjust
ment  range, as far  away from  the  a irbag 
as poss ible. The backrest  must  be adjust 
ed to  an upright  pos ition.  Make su re that 
the 
PASSENGER  AIR  BAG OFF light 
comes on and stays on all  the  time  when
eve r the  ignit ion  is switched  on. 
A WARNING 
-
- If  the PASSENGER  AIR  BAG OFF light 
does not  go o ut  when  an ad ult  is sitting 
on the  front  passenger  seat after  taking 
the  steps described  above, make sure the 
adu lt  is properly  seated  and  restra ined at 
one of  the  rear seating  pos itions. 
- Have the  airbag  system  inspected  by 
your  author iz ed Audi  dealer  before  trans
port ing anyone  on the  front  passenger 
seat . 
(j) Tips 
If  the  weight-sensing  mat  in the  front  pas
senger  seat detects  an empty  seat,  the 
front  airbag  on the  passenger  side will  be 
turned  off,  and the 
PASSENGER  AIR  BAG 
OFF 
light  will  stay on. 
Repair , care and  disposal of the  airbags 
Pa rts  of  the  airbag  system  are installed  at 
many different  places on your  Aud i.  Insta lling, 
removing,  servicing  or  repa iring  a part  in an 
area of  the  vehicle  can damage  a part  of  an  ..,.

Intelligent  technology Notice  about  data 
recorded  by  vehicle 
control  modules 
Your vehicle  is not  equipped  with  an  Event Da
ta  Recorder  (EDR), installed  by some  manu
facturers  for the  express  purpose of  capturing 
data  for  retrieval  after  an accident  or  crash 
event.  EDR's are sometimes  called  "crash  re
corders". 
Some  state laws restrict  the  retr ieval or  down
loading  of  data  stored  by  EDR's that  were  in
stalled  in a vehicle  for  the  express purpose  of 
retrieving  data  after  an accident  or  crash 
event  without  the  owner's  consent. 
Although  your  vehicle  is not  equipped  with  an 
EDR, it  is equipped  with  a number  of  electron
ic  control  modules  for  various  vehicle  systems 
such as, for  examp le, engine  function,  emis
sion  control,  as well  as for  the  airbags  and 
safety  belts. 
These electronic  control  modules also record 
vehicle-related  data  during  norma l vehicle  op
eration  for  diagnostic  and repair  purposes. 
The  recording  capacity  of  the  electronic  con
trol  modules  is limited  to data  (no sound  is re
corded)  and only  a small  amount  of  data  is ac
tually  recorded  over a very limited  period  of 
time  and stored  when  a system  fault  or other 
condition  is sensed by  a control  unit. Some of 
the  data  then  stored  may relate  to vehicle 
speed,  direction,  braking  as we ll as  restraint 
system  use and performance  in the  event  of  a 
crash or  other  condition.  Stored  data  can only  be read and downloaded  with  special  equip
ment. 
Electronic  Stabilization 
Program  (ESP) 
Description 
ESP  helps  to improve  road  holding  and vehicle 
dynamics  to  help  reduce the  probability  of 
skidding  and  loss of  veh icle control.  It  works 
only  when  the  engine is running.  ESP detects 
Intelligent  technology  161 
certain  difficult  driving  situations,  including 
when  the  vehicle  is beginning  to  spin  (yaw) 
out  of  control  and  helps you to  get  the  veh icle 
back under  control  by se lectively  braking  the 
wheels,  and/or  reducing engine  power  and 
providing  steering  ass istance to  help  hold  the 
vehicle  on  the driver's  intended  course.  The in
dicator  light 
G] in the  instrument  cluster 
blinks  when  ESP is taking  action to help  you 
control  the  vehicle. 
ESP has  limitations.  It is important  to  remem
ber that  ESP cannot  overcome  the laws of 
physics. 
It will  not  always be able to  help  out 
under  all  conditions  you may  come  up  against. 
For  example,  ESP may not  always be able to 
help you  master  situations  where  there  is a 
sudden  change in  the  coefficient  of  friction  of 
the  road surface.  When  there  is a section  of  dry  road that  is suddenly  covered with  water, 
slush  or  snow,  ESP cannot  perform  the  same 
way  it would  on the  dry  surface . If  the  vehicle 
hydroplanes  (rides  on a cushion  of  water  in
stead  of  the  road surface),  ESP will  not  be 
able  to help  you  steer  the  vehicle because  con
tact  with  the  pavement  has been  interrupted 
and the  vehicle  cannot  be braked or  steered . 
During  fast  cornering,  particularly  on winding 
roads,  ESP cannot  always  deal as effectively 
with  difficult  driving  situations  as at  lower 
speeds. When  towing  a trailer,  ESP is not  able 
to  help  you  regain  control  as it  would  if you 
were  not tow ing a trailer. 
A lways adjust  your  speed and driving  style  to 
road,  traffic;  and weather  conditions.  ESP can
not  override  the  vehicle's  physical  limits,  in
crease the  available  traction,  or keep a vehicle 
on  the  road  if  road departure  is a  result  of 
driver  inattention.  Instead,  ESP improves  the 
poss ibility  of  keeping  the  vehicle  under  con
trol  and on  the road  dur ing extreme  maneu
vers by  using the driver's  steering  inputs  to 
help  keep  the  vehicle  going  in the  intended  di
rection.  If  you  are traveling  at  a speed that 
causes you to  run  off  the  road  before  ESP can 
provide  any assistance, you  may not  experi
ence the  benefits  of  ESP .

Energy  management 
Starting  ability  is optimized 
Energy management  controls  the  distribution 
of  electrical  energy and  thus  optimizes  the 
availability of  electrical  energy for starting the  engine . 
If  a vehicle  with  a  conventional  energy  system 
is not  driven  for  a  long  period  of  time , the  bat
tery  is discharged  by  idling  current  consumers 
(e.g.  immobilizer).  In ce rtain  c ircumstances  it 
can  result  in there  being  insuff icient  ene rgy 
avai lab le  to  start  the  engine . 
Intell igent  energy  management  in your  vehi
cle  hand les  the  d istribution  of  electrical  ener
gy.  Starting  ab il ity  is  markedly  improved  and 
the  life  of  the  battery  is extended. 
Basically,  energy  management  consists  of 
batt ery  di agno sis, idlin g current  man ag e
m ent 
and dyn ami c en ergy  m anage ment . 
Batter y diagnosis 
Battery  diagnosis  continuously  determines 
the  state  of  the  battery . Sensors  determ ine 
battery  vo ltage,  battery  current  and  battery 
temperature.  This  dete rm ines  the  current 
state  of  charge  and  the  powe r of  the  battery. 
Idling  curr ent  man agement 
Idling  current  management  reduces  ene rgy 
consumption  while  the  vehicle  is stand ing . 
W ith  the  ignition  switched  off,  it  cont ro ls the 
energy  supply  to  the  va rious  electr ical  compo 
nents . Data  from  battery  diagnosis  is consid
ered. 
Depending  on  the  battery's  state  of  charge, 
i nd ividua l consumers  are  gradual ly t urned  off 
to  prevent  excess ive d ischarge  of  the  bat tery 
and  thus  maintain  starting  capability . 
Dynamic en ergy management 
While  the  vehicle  is  being  driven,  dynamic  en
e rgy management  dist ributes  the  energy  gen
e rated  according  to  the  needs  of  the  individu
a l components. 
It reg ulates  cons umption,  so 
that  more  electrical  energy  is  not  being  used 
Int ellig ent  technolog y 167 
than  is  being  generated  and  ensures  an  opti 
mal  state  of  charge  for  the  battery. 
(0 Tips 
- But  even  energy  management  canno t 
negate  the  limits  of  physics . Consider 
that  the  power  and  life  of  a  battery  are 
limited . 
- If  starting  ability  is threatened,  you  are 
informed  by a warning 
r:!) page  168, 
Driver notification  in the  instrument 
cluster  display. 
What  you should  know 
The highest  priority is given  to maintaining 
starting  capability. 
The  battery  is severe ly taxed  in  short -distance 
driving,  in city  traffic  and  during  the  cold  time 
of  year.  Abundant  electrical  energy  is  re quired,  but  only  a  little  is  generated . 
It is also 
critical  if the  engine  is not  running  and  electri
cal  components  are  turned  on . In  this  in
stance  energy  is  be ing  consumed  but  none  is 
being  generated. 
It  is  in  precisely  these  situations  that  you  will 
notice  energy  management  actively  regulat 
ing  the  d istribution  of  energy . 
Vehicle stands for an e xtended  peri od 
If you  do  not  drive  your  vehicle  over  a  period 
of  several  days  or  weeks,  e lectr ical  compo
nents  are  gradually  cut  back  or  switched  off. 
This  reduces  energy  consumption  and  ma in 
ta ins  start ing  capability  over  a  longer  period . 
Take  into  considerat ion  that  when  you  unlock 
your  vehicle,  some  convenience  functions,  such  as  the  remote  key or  power  seat  adjust
ment,  may  not  be  available . The  conven ience 
funct ions  w ill be  available  again  when  you 
tu rn on  the  ignition  and  start  the  engine . 
With  the engine turned  off 
If you  listen  to  the  radio,  for  example,  w ith 
the  engine  turned  off,  the  battery  is  being  d is-
charged.

168  Intelligent  technology 
If starting  capability  is jeopa rdized  due  to  en
ergy  consumption,  a  message  appears  in the 
driver  information  disp lay. 
You have  to  start  the  eng ine  to  charge  the 
battery. 
With  the  engine  running 
A lthough  electrical  energy  is generated  when 
the  vehicle  is  be ing  driven,  the  battery  can  be
come  discha rged.  This  happens  mos tly when 
little  e nergy  is  be ing  generated  and  a  great 
dea l consumed  and  the  battery's  state  o f 
charge  is not  optima l. 
To br ing  the  energy  balance  back  into  equili 
brium,  cons umers  which  require  especia lly 
l arge  amo unts  of  energy  are  temporari ly c ut 
back  or  switched  off.  Heating  systems  in  par
ticular  requ ire  a  great  dea l of  energy.  If you 
notice,  for  example,  that  the  heated  seats*  or 
the  heated  rear  window  are  not  heating,  they  have  been  temporar ily cut  back  or  switched 
off. These  systems  will  be  ava ilable  again  as 
soon  as  the  energy  ba lance  has  bee n restored. 
You will  a lso  notice  that  engine  idle  speed  has 
been  increased  s lightly . This  is  norma l and  not 
a  cause  fo r co ncern . By increas ing  engine  idle 
speed  the  add itiona l ene rgy  required  is  gene r
ated  and  the  ba tte ry is  charged. 
Driver  notification  in the  instrument 
cluster  display 
If  batte ry power  drops  into  the  range  w here  it 
can  limit  the  ab ility  of  the  engine  to  start,  th is 
is shown  in the  instrument  cluster  display 
with  the  following  driver  message: 
(•)  Low batter y charge : batte ry will  be 
charged while dr iving 
This  notif ication  reminds  you  tha t the  s tarti ng 
capability  of  the  engine  may  be  limited.  As 
soon  as  you  start  d riving  again,  the  battery 
will  be  recharged  and  the  notification  wi ll go 
out. 
Driver  notification  appears  and  goes out 
again 
If  this  driver  notif ication  appears  after  the  ig
nition  is t urned  on  or  whi le  driving  and  it  goes 
out  again  after  a while,  the  battery  has  been 
adequately  recharged. 
Driver  notification  appea rs and  doe s not 
go out  again 
If  this  driver  notif ication  appears  after  the  ig
nition  is turned  on  or  whi le  driving  and  does 
not  go  out  again,  the  battery 's state  of  charge 
is  not  in the  optima l range.  Starting  ab ility  is 
rest ricted . H ave  t he  battery  chec ked  as  soon 
as  possib le  by an  autho rized  Aud i dea le r o r

176  Trailer  towing 
Always  app ly bra kes  early . When  driving 
downhill,  shift  into lower  gear  to  use  the  en
g ine  braking  effect  to  slow down  the  vehicle. 
Use  of  the brakes  alone  can cause  them  to 
overheat  and  fail. 
Coolant temperature 
The  coolant  temperature  gauge ¢ page  11 
must  be  observed  carefully.  If  the needle 
moves  close to  the  upper end  of  the  scale,  re
duce  speed  immed iate ly  and/or  switch 
off the 
a ir  cond itioner. 
If  the  coolant  temperature  warning  light  in 
the  instrument  cluster  starts  flashing 
J_, pull 
off the  road,  stop  and  let the  engine idle for 
about  two  minutes to prevent  heat  build-up. 
A WARNING 
Anyone  not  properly  restrained  in a  mov
ing  veh icle  is at  a  much  greater  risk  in  an 
accident . Never  let  anyone  r ide  in your  car 
who  is  not  prope rly wear ing  the  restra ints 
provided  by Aud i. 
Trailer  towing  tips 
Important  to  know 
Your veh icle  handles  different ly when  towing 
-
a  trailer  because  of  the addit io nal  weight  and 
weight  distribution . Safety,  performance  and 
economy  w ill greatly  depend  on  how  carefu lly 
you  load  your  trai ler  and  ope rate  your  rig . 
Before  you  actually  tow  your  trailer,  practice 
turn ing,  stopp ing  and  back ing  up  in an  area 
away  from  traffic.  Keep  practicing  until  you  have  comp letely  become  fam iliar  w ith  the  way 
your  ve hicle-trai ler  comb ination  behaves  and 
responds . 
Backing  up  is d iff icu lt  and  requires  practice . 
Backing  up  with  a tra ile r  genera lly requ ires 
steer ing  act ion  opposite  of  tha t when  backing 
up your  veh icle  without  a  trailer . 
Ma intain  a g reater  distance  between  your  ve
h icle  and  the  one  in fro nt  of you.  You will  need 
mo re  room  to  stop.  To compensate  for  the  trailer,  yo
u will  need  a 
larger  than normal  turning  radius. 
When  passing,  remember  that  you  cannot  ac 
ce le rate  as  fas t as  you  no rma lly would  be
cause  of  the  added  load.  Make  sure  yo u have 
enough  room to pass . After  passing,  a llow 
plenty  of  room for  your  trailer  before  chang 
ing  lanes  again. 
Avoid  jerky starts , sharp  turns  or  rapid  lane 
changes. 
(D Tips 
- Do not  tow  a  trailer  during  the  break -in 
period  of  your  vehicle. 
- If you  tow  a  trailer,  yo ur Audi  may  re
quire  more  frequent  maintenance  due  to 
the  extra  load  ¢ 
page  2 59. 
Parking on a slope 
Do not  park with a trailer  on  a slope . If  it can
not  be  avoided,  do  so only  after  doing  the  fol
lowing: 
When  parking: 
.,.  App ly  the  foot  brake. 
..  Have someone  p lace  cho cks  under  both  the 
veh icle  and  the  trailer  wheels. 
..  With  chocks  in  place,  slowly  release  the 
brakes  unti l wheel  b locks  absorb  th e  load. 
..  Turn  the whee ls towards  the  cu rb. 
..  App ly the  parking  brake. 
..  Place  an  automat ic transm ission  in 
P, re
spectively  a  manual  transmission  in first  or 
reverse  gear . 
When  restarting  after  p ark ing: 
..  Start  the  engine. 
..  Shift  transm ission  into  gear . 
..  Release  the  parking  brake  and  slowly  pull 
out  and away  from  the  wheel  blocks. 
.,.  Stop  and  have  someone  retr ieve  the  wheel

VW 507  00  (vehicles with  diesel  engine). 
C hang ing  th e  engin e oil 
The engine  oil and  oi l filter  must  be changed 
according  to  the  m ileage  (kilomete rs) and 
time  inte rva ls specified  in yo ur vehicle's War
ranty 
& Maintenance  booklet.  Do not exceed 
these  intervals  -harmful  deposits  from  old 
engine  oil can reduce  engine  performance  and 
can lead  to  expensive  eng ine repairs. 
Changing  the o il at  the  recommended  inter 
va ls is so very important  because  the  lubricat 
ing properties  of oi l decrease  gradually  during 
norma l vehicle  use . If you are  not  sure when 
you have your oi l changed,  ask your author
ized Audi Service Advisor. 
Under some  circumstances  the  engine  oi l 
should  even be changed  more frequently. 
Change o il more often  if you drive mostly 
short  distances,  operate  the vehicle in dusty 
areas  or  mostly  under  stop-and-go  traffic  con
d itions,  or when you use your veh icle where 
temperatures  stay below freezing  point  for 
l ong  periods. 
Detergent  addit ives in the  o il w ill make fresh 
oil look dark after  the  eng ine has  been  run
n ing for a short  time.  This is norma l and  is not 
a reason  to  change  the  o il mo re often  than 
r ecommended. 
D amage  or ma lf u nction s du e to  lac k of 
ma int enance 
It  is essential  that  you change  your oil at  the 
recommended  interva ls using  only engine  oil 
that  complies  with Audi oil standard 
VW 502  00  (veh icles with  gasolin e engine) or 
VW 507  00  (veh icles with  diese l engi ne). Yo ur 
L im ited  New Vehicle Warra nty does  not  cover

·  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  prov ide effective  lubrication  and 
cooling o f inte rna l engine  components,  all in 
ternal  combustion  engines  consume  a certain  amount  of oil. Oil consumpt ion varies from 
engine  to  engine  and  may change  sign ificantly 
over the  life of the  engine.  Typically, engines 
with  a spec ified  break-in period  (see 
Q page  169) consume  more  oil during  the 
break-in pe riod than  they  consume  after  o il 
consump tion has stabilized. 
Under normal  cond itions,  the  rate  of oi l con
sumption  depends  on the  quality  and viscos ity 
of the  oil, the  RPM (revolut ions  per  minute)  at 
which the  engine  is operated,  the  ambient 
temperature  a nd  road  conditions.  Further  fac 
tors  are  the  amount  of oil dilut ion from  wa ter 
condensation  or fue l residue  and  the  oxida 
tion  level of the  oi l. As any engine  is subject  to 
wear  as  mi leage  builds  up, the  oil consump
tion  may increase  over time  until  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 es
tablished  or spec ified. There is no alternative 
to  regular  and  frequent  check ing of  the oil lev
el,  see 
Not e. 
If the  yellow engine  oil level warning  symbo l 
in the  instrument  cluster 
Ill! lights  up, you 
shou ld check the  oil  leve l as soon  as  possib le 
with  the  oil dipstick q page  200 . Top off the 
o il at your earliest  conven ience

used  today  are  underinflated  just  by looking 
at  them. 
Therefore,  be  sure  to  check  tire  pressures  at  l eas t once  a  mon th  and  always  before  going 
on  a  long  trip.  Make sure  to  take  the  number 
of  people  and  the  amount  of  luggage  into  ac
count  when  adjusting  tire  pressure  for  a trip  -
even  one  that  you  would  not  consider  to  be 
"long."  See  ¢ 
page  220, Tires and  vehicle 
load  limits 
for  more  important  information . 
A lways  use  an  accurate  tire  pressure  gauge 
when  check ing  and  adjusting  inflation  pres
sures . Check all  of  the  tires  and  be  sure  not  to 
forget  the  spare  t ire . If  the  pressure  in any  tire 
is too  high  when  the  tire  is  "cold,"  let  air  out 
of the  tire  slowly  with  the  edge  of  the  t ire 
gauge  and  keep  checking  the  pressure  until 
you  reach  the  p ress ure  th at  is cor rect  for  the

Remember  that  the  vehicle  manufacturer,  not 
the  tire  manufacturer,  determines  the  co rrect 
tire  p ressure  for  the  tires  on  your  vehicle . 
It  is important  to  check  the  tire  pressure  when 
the  tires  are  cold . 
- Read  the  requ ired  ti re  p ressu re from  the  tire 
pressure  label.  On USA veh icles,  the  t ire 
pressure  label  is  located  on  driver's  side  8-
pillar . On Canada  vehicles,  the  tire  pressure 
label  is located  either  on  the  driver's  side  8-
pillar  or  inside  the  fuel  fi ller  flap. 
- Turn  the  valve  stem  cap  counter-clockwise 
to  remove  it from  the  tire  valve. 
- Place  the  air  pressure  ga uge  on  the  valve.

- The  tire  pressures  should  only  be  checked 
and  adj usted  when  the  tires  are  co ld . The 
slightly  raised  pressures  of warm  tires  must 
not  be  reduced. 
- Adjust  the  tire  pressure  to  the  load  you  are 
carrying. 
- Reinstall  the  valve  stem  cap  on  the  va lve. 
When  should  I  check the  tir e pressu re? 
T he  co rrect  tire  pressu re  is especially  impor 
tant  a t  high  speeds.  The  pressure  should 
therefore  be  checked  at  least  once  a  month 
and  always  before  starting  a jo urney . Do not 
forget  to  check  the  tire  pressure  for  the  spare

A WARNING 
...---
Incorrect  tire  pressures  and/or  underinfla-
tion  can  lead  sudden  tire  fa ilure,  loss  of 
control,  collision,  serio us  personal  injury 
or  even  death. 
- When  the  warning  symbol 
ti] appears  in 
the  instrument  cluster,  stop  and  inspect 
the  t ires. 
- Inco rrect  tire  pressure  and/or  underinfla
tion  can  cause  increased  tire  wea r and 
can  affect  the  hand ling  of  the  vehicle  and 
s topping  abi lity. 
- I nco rrect  tire  pressures  and/or  unde rin
flation  can  a lso  lead  to  sudden  t ire  fail

properly . Always  check  the  TPMS malfunction 
tellta le  after  replacing  one or  more  tires or 
wheels  on your  vehicle  to ensure  that the  re
placement  or  alternate  tires  and  wheels allow 
the  TPMS  to  continue  to function  properly.
