Warm  and  cold 
Warm  and  cold 
Climate  control 
Description 
The air conditioner  is fully  automatic  and  is designed  to 
maintain  a  comfortable  and  uniform  climate  inside  the 
vehicle. 
We  recommend  the  following  settings: 
- Set  the  temperature  to  75  °F (+23  °C). 
- Press  the  [AUTO]  button. 
With  this  setting,  you  attain  maximum  comfort  in the  least  amount 
of  time.  Change  this  setting , as  desired,  to  meet  your  personal  needs. 
The  climate  controls  are  a  combination  of  heating,  ventilation  and  cooling  systems,  which  automatically  reduce  humidity  and  cool  the 
air  inside  your  vehicle. 
The  air  temperature,  air  flow  and  air  distribution  are  automatically  regulated  to achieve  and  maintain  the  desired  passenger  compart
ment  temperature  as  quickly  as  possible . 
The  system  automatically  compensates  for changes  in  outside 
temperature  and  for  the  intensity  of  the  sunlight  entering  the 
vehicle.  We  recommend  you  use  the 
Automatic mode=> page 99 for 
year-round  comfort . 
Please  note  the  following: 
Turn on the  air conditioner  to  reduce humidity  in the  vehicle.  This also 
prevents  the  windows  from  fogging  up . 
When  the  outside  temperature  is high  and  the  air  is very  humid, 
condensation from  the  evaporator  may  drip  under  the  vehicle.  This is 
normal  and  does  not  indicate  a  leak.  If the  outside  temperature 
is low,  the  fan  normally  only  switches  to  a 
higher  speed  once  the  engine  coolant  has  warmed  up  sufficiently . 
The  air  conditioner  temporarily switches  off  when  you  drive  off  from 
a standstill  using  full  throttle  to  save  engine  power. 
The  compressor  also  switches  off  if the  coolant  temperature  is too 
high,  so  that  the  engine  can  be  adequately  cooled  under  extreme 
loads. 
Air  pollutants  filter 
The  air  pollutants  filter  (a combined  particle  filter  and  activated  char
coal  filter)  reduces  or  prevents  outside  air  pollution  (dust,  or  pollen) 
from  entering  the  vehicle.  The  air  is also  filtered  in air  recirculation 
mode. 
The  air  pollutants  filter  must  be  changed  at  the  intervals  specified  in 
your  Warranty 
& Maintenance  booklet,  so that  the air  conditioner  can 
properly  work . 
If you  drive  your  vehicle  in an  area  with  high  air  pollution,  the  filter 
may  need  to  be  changed  more  frequently  than  specified  in your  Audi 
Warranty 
& Maintenance  booklet. If  in  doubt,  ask  your  authorized 
Audi  Service  Advisor  for  advice . 
Key  coded  settings 
The air  conditioner  settings  selected  are  automatically  stored  and 
assigned  to  the  key  being  used.  When  the  vehicle  is started,  the  air 
conditioner  automatically  selects  the  settings  assigned  to  that  key. 
This way every  driver  will  maintain  his/her  own  personal  settings  and 
does  not  have  to  reset  them manually. 
If  a  different  driver  uses  your  key and  changes  the  air  conditioner 
settings,  the  latest  adjustments  will  erase  and  replace the  settings 
you  have  stored .  _.,

Other  things  that  can  affect  Advanced 
Airbag  performance 
Chang ing  the  vehicle's  suspension  system  can  change  the  way that 
t h e Advan ced  Airbag  System  pe rforms  in a cr ash . For e xamp le,  usi ng 
tire-rim  combinations  not  app roved  by Audi,  lowering  the  vehicle, 
c hang ing  the  stiffness  o f th e suspension,  incl uding  the  sp rings, 
suspension  struts,  shock  absorbers  etc.  can  change  the  forces  that 
are  meas ured  by  the a irbag  sensors  and  sent  to  the  ele ct ronic contro l 
unit . Some  suspension  changes  can,  fo r exam ple,  increase  the  force 
levels  measured  by  the  senso rs and  make  the  airbag  system  deploy  in 
crashes  in which  i t would  not  deploy  if the  changes  had  no t been 
ma de . Other  kinds  of  changes  may  reduce  the  force  levels  meas ured 
by  the  sensors  and  p revent  the  airbag  from  dep loying  when  it should. 
T he sensors  in the  safety  belt  b uckle  for  the  drive r and  front 
p as senge r se at  tell  the  e lectroni c cont rol mo dule  if the  sa fe ty  belt  is

safety  belt  is  not  be ing used . Therefo re,  in a  par ticular  collis io n, it  is 
possible  that  an a irba g w ill not  dep loy at  a seating  position  where  the 
safety  belt  is  being  used  but  w ill inflate  at  the  posit ion  where  the 
safety  belt  is not  be ing  use d.  It  is  im portant  that  nothing  interfere

Driving  and  environment 
------------------------------------------------' 
The amount  of oil used is  related  to  engine  load and speed. 
It is normal  for  the  oil  consumption  of  a  new engine  to  reach its 
lowest  value  after  a certain  mileage  has been driven . 
You must  drive your  vehicle  about  3,000  miles  (5,000  kilometers) 
before  you can  properly  assess oil  consumption. 
This also applies  to  fuel  consumption  and engine  output . 
0 Note 
• Have  your  vehicle  maintained  properly  and in accordance with  the 
service recommendations  in your  Warranty 
& Maintenance booklet. 
Lack  of  proper  maintenance  as well as improper  use of the vehicle w ill 
impair  the  function  of  the  emission  control  system  and cou ld  lead to 
damage. 
•  Do not  alter  or  remove any component  of  the  Emission  Control 
System  un less approved  by the manufacturer. 
•  Do not  a lter  or  remove  any device, such as heat  shie lds, switches, 
ignition  wires,  valves, which  are designed  to  protect  your  vehicle's  Emission Contro l System  and other  important  vehicle  components. • 
Fewer  short  trips 
Fuel consumption  will always be  relatively  high  on short 
trips . 
-Try  to avoid  driving  short  distances  with  a cold  engine. 
The eng ine and  catalytic  converter  have to  reach thei r optima l oper
ating  temperature 
to  reduce fuel  consumption  and noxio us em is
sions effectively. 
Just  after  starting,  a cold  engine  in a mid -size  car only  achieves a  fuel 
economy  of  6-8  miles  per gallon  (30-40  l/l00km). After  about  a  half 
a mile,  fuel  economy  climbs  to  12 mpg  (20  l/100  km). After  about 
2.5 miles  (4  km),  the  engine is at  its  proper  operating  temperature 
Controls  and  equip
ment  Safety  first  Vehicle  operation 
and fuel  economy  has 
reached a normal  level.  So you can see that  you 
should  avoid short trips whenever  possible. 
The 
outside  temperature is also cr it ical  in th is regard . Your  car 
consumes  more  fuel  in the  winter  than  in the  summer. •

Changing the engine  oil 
The engine  oil and  oil fi lter  must  be  changed  according  to  the  mileage 
(kilometers)  and  t ime  intervals  specified  in your  vehicle 's Warranty 
& 
Maintenance  booklet . Do not  exceed  these  interva ls  -harmful 
deposits  from  o ld  engine  oil  can  reduce engine performance  and  can 
lead  to  expensive  engine  repairs . 
Changing  the  oil at  the  recommended  intervals  is so  very  impo rtant 
because  the  lubricating properties  of  o il decrease  gradually  during 
normal  vehicle  use.  If you  are  not  sure  when  you  have  your  oil 
changed,  ask  your  author ized  Audi  Service  Adv isor . 
Under  some  circumstances  the  engine  oil  should  even  be changed 
mo re frequently.  Change  oil  more  often  if you  drive  mostly  short 
distances,  operate  the  vehicle  in dusty  areas  or  mostly  under  stop
and-go  traffic  conditions,  or when  you use your  vehicle  where  temper
atures  stay  be low freezing  point  for  long  periods. 
Detergent  addit ives  in the  oi l wi ll make  fresh  oil  look  dark  after  the 
engine  has been  running  for  a  short  t ime.  This  is normal  and  is not  a 
reason  to  change  the  oil  more  often  than  recommended . 
Damage or malfunctions  due to  lack of maintenance 
It is essential  that  you  change  your  oil  at  the  recommended  intervals 
using  only  engine  oi l that  complies  with  Audi  oil  standard 
VW 502  00.  Your  Limited  New Vehicle War ranty  does  not cover 
damage  or  malfunctions  due to  fai lure  to  follow  recommended  main
tenance  and  use  requirements  as  set  forth in the  Audi  Owner 's 
Manual  and  Warranty 
& Maintenance  booklet.  Your  dealer  will  have 
to  deny  warranty  coverage  unless you  present  to  the  dealer  proof  in 
the  form  of  Serv ice  or  Repair  Orders  that  all  scheduled  maintenance 
was  performed  in a time ly manner. • 
Engine  oil  consumption 
The engine  in your vehicle depends  on  an  adequate 
amount  of oil to lubricate  and cool  all of  its moving  parts. 
In  order  to  provide  effective  lubrication  and  cooling  of  internal 
eng ine components,  all inte rnal  combustion  engines  consume  a 
certain  amount  of  oil.  Oil consumption  varies  from  engine  to  engine 
and  may  change  sign ifican tly  over  the  lif e  of  the  engine.  Typically, 
engines  with  a  specified  break- in  period  (see~ 
page  251) consume 
more  oil  during  the  break-in period  than  they  consume  after  oil 
consumption  has  stab ilized . 
Under  normal  conditions,  the  rate of  oil  consumption  depends  on  the 
quality  and viscosity  of  the  oil,  the  RPM (revolutions  per minute)  at 
which  the  engine  is operated,  the  ambient  temperature  and  road 
conditions.  Further factors  are  the  amount  of  oil  dilution  from  water 
condensation  or  fuel  residue  and  the  ox idation  level  of  the  oil.  As any 
eng ine is  subject  to  wear as  mileage  builds up, the  oil  consumption 
may increase over time until replacement of worn components may 
become  necessary. 
With  all these  variab les coming  into  play,  no  standard  rate  of  oil 
consumption  can  be  established  or  specified . There  is no  alternative 
to  regular  and  frequent  checking  of  the  oil  level , see 
Note . 
If  the  yellow  engine  oil  leve l warning  symbol  in the  instrument 
cl uster  lights up,  you  should  chec k the  oil  level  as  soon  as  possible 
with  the oil dipstick~ page  283. Top off the  oil  at  your  earliest 
convenience ~ 
page  284. 
& WARNING 
Before you check  anything  in the  engine  compartment,  always 
read and  heed all  WARNINGS~ 
& in "Working  in the  engine 
compartment"  on 
page 279.

ment"  on  page 279. 
T he eng ine oil  mus t be  changed  acco rding  to  the  intervals  specifie d in 
your Warranty 
& Maintenance  book let . This is very  important  because 
the  lub ricating  properties  of  oil  diminish  gradually  during  norma l 
vehicle  use . 
Under  some  circumstances  the  eng ine o il sho uld  be changed  more 
frequently.  Ch ange oi l more  ofte n if you  drive mos tly short  distan ces, 
operate  the  vehicle  in dusty  areas or  under  predominant ly stop-and
go tr affic  condi tions , or  have yo ur vehicl e where  temperat ures  rem ain 
below  freezing  for  extended  per iods. 
Detergent  a dditives  in the  o il w ill  make fres h oil  look  dark  after  the 
eng ine has been ru nning for  a s hort  ti me.  Th is is normal  an d is  not  a 
reason to  change the  oil  mo re often  than  recommended. 
B eca u se of  the  proble m of  pr oper di sp o sal,  along w ith  the s pe cial 
too ls and necessary expertise  required , we strong ly recommend  that 
yo u have your  o il changed  by an a uth o rized 
Audi dealer o r a qua lified 
service stat io n. 
If you  choose  to  change  your oil  yourself , please note  the  following 
i m po rtan t  informatio n: 
& WARNING 
To reduce the  risk of  personal  injury if you  must  change  the  engine 
oil  in your vehicle  your self: 
•  Wear  eye  protection. 
•  To reduce  the  risk of  burns  from  hot  engine  oil,  let  the  engine 
cool  down  to  the  touch. 
Safety  first 
& WARNING (co ntinued ) 
• 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 .

Brake  fluid  will  damage  the  paint  of  your  vehicle. 
Because  of  the problem  of  proper  disposal  of  brake  fluid  as  well  as 
the  special  tools  required  and  the  necessary  expertise,  we  recom
mend  that you  have  the brake  fluid  changed  by your  authorized  Audi 
dealer. • 
Battery 
General  information 
Under normal operating  condit ions,  the battery  in your  Aud i does  not 
need  any  maintenance.  With 
high outside  temperatures  or  long  daily 
drives  we  recommend  that  you have the  electrolyte  level  checked  by 
a  service  facility.  The electrolyte  level  should  also  be checked  each 
time  the  battery is  charged~ 
page 292. 
Have the  battery  checked  when  you  take  your  vehicle  in  for service. 
You  are well  advised  to replace  a  battery  that  is older than  5 years. 
With  certain  types  of  a irbag  deployment,  the  battery  is disconnected 
from  the  vehicle  electrical  system  for  safety  reasons=> 
& in "Repair, 
care  and  disposal  of  the airbags"  on 
page 211. 
Disconnecting  the  battery  terminals 
Some  vehicle  functions  (power  window  regulators,  for  example)  are 
lost  if the battery terminals  are  disconnected.  These  functions  have 
to  be  relearned  after  the  battery  terminals  are  connected  aga in.  To 
prevent  this,  the  battery  should  only  be disconnected  from  the 
vehicle  electrical  system  when  absolutely  necessary  for  repairs. 
Vehicles  not  driven  for  long  periods 
If you  do  not  drive  your  veh icle  over  a  period  of  severa l days  or weeks, 
electrical  components  are  gradually  cut  back  or  switched  off.  This 
reduces  energy  consumption  and  maintains  starting  capability  over  a 
longer  period~ 
page 249. 
Take  into  consideration  that  when  you  unlock your  vehicle,  some 
convenience  functions,  such  as  the master  key  remote function  or 
power  seat  adjustment,  may  not  be  available.  The  convenience  func
tions  will  be  available  again  when  you  turn  on  the  ign ition  and  start 
the  engine. 
Winter  operation 
During  the  winter  months,  battery  capacity  tends  to  decrease  as 
temperatures  drop. This  is because  more power  is  also consumed 
while  starting,  and  the  headlights,  rear  window  defogger,  etc.,  are  used  more  often . 
Avoid unnecessary  power  consumpt ion,  particu larly  in city  traffic  or 
when  traveling  only  short  distances.  Let your  authorized  Audi  dealer 
check the  capacity  of  the  vehicle  battery  before  w inter  sets  in 
=> page 292.  A well  charged  battery  will  not  only  prevent  starting 
problems  when  the weather  is cold,  but will  also  last  longe r. 
(I] Tips 
If  your  veh icle  is  left  standing  for  several  weeks  at extreme ly  low 
temperatures,  the  vehicle  battery  should  be removed  and  stored 
where  it will  not  freeze. This  will  prevent  it  from  being  damaged  and 
having  to  be  replaced.•
