-When  switching  the  ignition  on,  the  needles 
in the  instrument  cluster  swing  upward 
briefly. 
- The  illumination  for  the instrument  cluster 
lights  up whenever  you  switch  on the igni
tion  with  the 
vehicle  headlights  off. As the 
daylight  fades,  the  instrument  cluster  illu
mination  likewise dims  automatically  and 
will go  out  completely  when the  outside 
light  is very low . This  feature  is meant  to re
mind  you  to switch  on  the  headlights  when 
outside  light  conditions  become  poor.

Engine coolant temperature  gauge 
The engine  coolant  gauge¢ page 10, fig.  3@ 
only works  when  the  ignition  is on. To prevent 
damage  to  your  engine,  please  note  the  follow ing  important  points: 
Engine cold 
If the  needle  is  at or close  to  the  bottom  of the 
gauge,  the  engine  has  not yet reached  its operat
ing  temperature.  Avoid high  engine  speeds, 
heavy engine  loads,  and  heavy throttle  applica
tions . 
Normal  temperature 
When  the  engine  has  reached  its operating  tem 
perature,  the  needle  will move to  the  middle  of 
the  gauge  and  remain there. If the  engine  is 
working  hard at high  outside  temperatures,  the 
needle  may  move  higher  on the  gauge . This  is not 
a cause  for concern  as  long as the . warning 
li ght  i n the  inst rument  cluster  display  does  not il
luminate . If  the . warning  light in the  instru
ment  cluster  display  flashes,  this  can mean  one 
of  two  things : either  the  coolant 
temperature is 
too  high,  or  the coolant 
level is too  low

A WARNING 
-Always  observe  the  warning  in ¢ page  203, 
before  opening  t he  hood  and  checking  the 
engine  coolant  level. 
- Never  open  the  engine  hood  if you  see  or 
hear  steam,  or  if you  see  engine  coolant 
dr ipping  from  the  engine  compartment.  You 
cou ld  burn  yourself.  Let the  engine  cool  off 
firstsothatyoucannothearo rseeany 
steam  or  engine  coo lant. 
0 Note 
- Mounting  additional lights or  accessories  in 
front  of the  air  inlets  reduces  the  cooling  ef
fect  of the  radiator.  At h igh  outside  temper
atu res  or  high  engine  load,  the engine  could 
overheat. 
- The  front spoiler  has  been  designed  to  prop
erly  distribute  the  cooling  air when  the  vehi
cle  is  moving.  If the  spoiler  is  damaged, this 
could  reduce  the  cooling  effect  and  the  en
gine  could  then  overheat.  Ask your  author
ized  Audi  dealer  for  assistance. 
Tachometer  (engine  rev counter ) 
The tachometer  indicates  the  engine RPM (revo
lutions  per  minutes). 
If  engine  RPM drops  below  1,500,  you  should 
downshift  to  the  next  lower  gear.  The  red  area  at 
the  end  of the  scale  indicates maximum  permis
sible  eng ine  RPM  after the  break-in  period.  Be
fore  reaching  this  area,  move the selector  lever 
to  position  D/5  or  ease  your  foot  off  the  accelera
tor  pedal. 
(D Note 
The  tachometer  needle@¢ page  10,  fig.  3 
should  only  briefly  be  in the  red  zone: you 
could  damage  your  eng ine!  The  beginning  of 
the  red  zone  varies depending  on the  engine. 
@ For the  sake of the  environment 
Upshifting  early saves fuel  and  reduces  en
gine  noise.

Warm  and  cold 
Warm  and  cold 
Climate  control  system 
Description 
The  climate  control  system  warms,  cools  and 
adds  humidity  to  the  air  in the  veh icle  inter ior.  It 
is the  most  effective  when  the  windows  and  sun 
roof  are  closed.  If  there  is a  build-up  of  heat  in
side  the  vehicle,  ventilation  can  help  to  speed  up 
the  cooling  process. 
I n all  heating  mode  functions  except 
defrost, the 
b lower  only  switches  to  a  higher  speed  once  the 
engine  coolant  has  reached  a  certain  tempera
ture . 
Condensat ion  from  the  cooling  system  can  drip 
and  form  a  puddle  of  water  under  the  veh icle. 
This  is normal  and  does  not  mean  there  is a  leak. 
P ollutant  filt er 
The  pol lutant  filte r removes  pollutants  such  as 
dust  and  pollen  from  the  a ir. 
The  air  pollutants  filter  must  be  changed  at  the  intervals  specif ied  in your  Warranty 
& Mainte
nance  booklet,  so  that  the  a ir cond it ione r can 
properly  work. 
If you  drive  your  vehicle  in an  area  with  high  air  pollut ion,  the  filter  may  need  to  be  changed 
more  frequently  than  specified  i n your  Aud i War
ranty 
& Maintenance  booklet.  If  in doubt,  ask 
your  author ized  Audi Service  Advisor  for  advice. 
Ke y cod ed  setting s 
The  climate  control  settings  are  automatically 
stored  and  assigned  to  the  remote  control  key 
that  is  in use . 
.8, WARNING 
Reduced  visib ility is dangerous  and  can  ca use 
accidents. 
- For  safe  dr iv ing  it  is very  impo rtan t that  all 
windows  be  free  of  ice,  snow  and  condensa
t ion . 
76 
- Complete ly familiarize  yourself  with  the 
proper  use  and  function  of  the  heating  and 
ventilation  system  and  espec ially  how  to  de
fog  and  defrost  the  wi ndows . 
- Never  use  the  windshield  wiper/washer  sys
tem  in freezing  weather  until  you  have 
warmed  the  windshield  first,  using  the  heat ing  and  vent ilation  system.  The  washer  solu
tion  may  freeze  on  the  windshield  and  re
duce  visibi lity. 
(D Note 
- If you  suspect  that  the  air  conditioner  has 
been  damaged,  sw itch  the  system  off  to 
avoid  further  damage  and  have  it  inspected 
by a  q ualified  dealership. 
- Repa irs  to  the  Aud i air  cond itioner  requ ire 
special  techn ica l know ledge  and  spec ial 
tools.  Contact  an  a uthorized  Audi  dealer  fo r 
assistance. 
@ For the  sake of  the  environment 
By reduc ing  the  amo unt  of  fuel  you  use,  you 
also  reduce  the amount  of pollutants  emitted 
into  the  a ir. 
(D Tips 
- Keep  t he  a ir intake  slots  (in front  of  the 
windshield)  free  from  ice,  snow  and  debr is 
in orde r to  maintain  the  prope r funct ion  of 
the  climate  control  system . 
- The  energy  management  sys tem  may  sw itch 
the  seat  heating*  o r rea r window  defroster 
off  temporarily.  These  systems  are  available 
again  as  soon  as  the  energy  balance  has 
been  restored. 
- Air escapes  through  vents  under  the  rear 
window.  When  placing  items  of  clothing  on 
the  luggage  compartment  cover,  ensure 
that  the  openings  are  not  covered.

Weight  distribution 
T owing  a loaded  trailer  w ith  an  empty  car  res ults 
in a high ly unstable  distribution  of weight . If this 
cannot  be avo ided,  drive at  very low speeds  o nly 
to  avoid the  risk of  losing  steering  control. 
Trailer  mode 
A "ba lanced"  rig is easier  to opera te and  co ntrol. 
This means  that  the  tow  vehicle  sho uld  be loaded 
to  the  extent  possib le and  permissib le, w hile 
keeping  the  trailer  as  light  as  possible  under  the 
cir cumstances . Wheneve r poss ib le,  transfer 
some  cargo  to  the  luggage  compartment  of the 
tow  ve hicle while  observing  tongue  load  require
