Setting  the  magnetic  deflection  zone 
The correct  magnetic  deflection  zone  must  be set  in  order 
to  display  the  directions  correctly.

Calibrating  the  compass 
The compass  has  to be recalibrated  if  the  display  is wrong 
or  inaccurate. 
Hold  the© button  down  until  the letter C is displayed  on 
the  interior  rear  view  mirror. 
Drive  in a circle  at  a speed  of  about  5 mph  (10 km/h)  until 
a  direction  is shown  on the  interior  rear view  mirror. 
& WARNING 
The  digital  compass  is to  be  used  as a directional  aid  only. Even 
though  you may  want to  look at  it  while  you  are driving,  you must 
still  pay  attention  to  traffic,  road  and  weather  conditions  as well 
as  other  possible  hazards . •

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. 
& WARNING 
Reduced visibility  is dangerous  and  can  cause  accidents . 
•  For safe driving  it  is very  important  that  all windows  be free  of 
ice, snow  and  condensation. 
•  Fully familiarize  yourself  with  the  proper  use and  function  of 
the  heating  and  ventilation  system  and  especially  how  to  defog 
and  defrost  the  windows. 
•  Never  use the  windshield  wiper/washer  system  in freezing 
weather  until  you  have warmed  the  windshield  first,  using the 
heating  and ventilation  system.  The  washer  solution  may  freeze 
on the  windshield  and  reduce  visibility. 
0 Note 
•  If you  suspect  that  the air  conditioner  has been  damaged,  switch 
on  ECON and  contact  an  authorized  Audi  dealer  to  have the  system 
inspected. 
•  Repairs  to  the  Audi  air  conditioner  require  special  technical 
knowledge  and  special  tools.  Contact  an  authorized  Audi dealer  for 
assistance. 
[  i] Tips 
•  Keep the  air  intake  slots  (in front  of  the  windshield)  free  from  ice, 
snow  and  debris  in  order  to  maintain  the proper function  of the 
climate  control  system. 
•  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. 
Controls  and  equip 
ment 
•  If  the  inside  temperature  is very  high  (for  example,  if  the vehicle 
has  been  parked  in  sun),  open  the  windows  and  allow  the  hot  air  to 
escape  before  turning  on  the  air  conditioner. •

& WARNING 
•  Unintended  vehicle  movement  can  cause  serious  injury . 
- When  the  selector  lever  is  in  a  driving  position , the  vehicle 
may  creep , even  at  idle  speed . Therefore  do  not  release  the 
parking  brake  or  foot  brake  until  you  are  ready  to  move, 
because  power  is  transmitted  to  the  wheels  as  soon  as  a 
driving  position  is  engaged. 
- Do  not  accelerate  while  selecting  a  driving  position . At  this 
time  the  engine  must  be  at  idle  speed  so  that  undue  stress  is 
not  placed on the  clutches  in the  transmission . 
- Remember: -even  when  stopped  briefly  with  the  automatic 
transmission  in  "D ",  "S " or  "R ",  engine  power  is  being  trans
mitted  to  the  wheels.  Your  vehicle  could  "creep" forward  or 
ba ckward . When  stopped , keep  the  brake  pedal  fully  depressed 
and  use the  parking  brake  if  necessary  to  keep  the  vehicle  from 
rolling . 
•  If  the  selector  lever  is  unintentionally  moved  into  N while  you 
are  driving , take  your  foot  off  the  accelerator  pedal  and  wait  for 
the  engine  to  return  to  idle  speed  before  selecting  a driving  posi 
tion . 
•  Never  shift  into  "R "  or  "P "  when  the  vehicle  is  in  motion . 
•  Never  get  out  of  the  driver 's  seat  when  the  engine  is  running . 
•  If  you  must  get  out  of  the  vehicle , move  the  selector  lever 
securely  into  the  P pos ition  and  apply  the  parking  brake  firmly . 
•  If the  engine  must  remain  running , never  have  any  dr iving  posi 
tion  engaged  when  checking  under  the  hood . Make  sure  the
