Deluxe  automatic  climate  control 
Applies  to  vehicles:  with  deluxe  automat ic  climate  cont ro l 
Description 
The climate  control  system  can be  used  to  set  a comfort
able  temperature  inside  the  vehicle . 
The  climate  control  system  is a  combination  of a  heating  and  ventila
tion  system  as  well  a  cooling  system  respons ible  for  dehumid ifying 
and  cooling  the  air  inside  the  vehicle. 
Th e  automatic  climate control  system  automatically  maintains  a 
temperature  once  it  has  been  set.  The  temperature  of  the  air from 
the  vents,  fan  speed  (air  volume)  and  air  distribution  are  a lso  auto
matically  adjusted . The  system  also  takes  into  account  strong 
sunlight so that  manual adjustment is  not necessary . So  in almost all 
cases, automatic  mode offers  the  best  conditions  for  the  comfort  of 
the  occupants  at  all  times  of the  year=> 
page 90. 
Please  note  the  following : 
The cooling  mode  lowers  the  humidity level  inside  the  vehicle.  This 
prevents  fogging  up  of  the  windows. 
In  the  case  of  high  outside  humidity and  temperatures, 
condensation 
can  drip  from  the  air conditioning  system  evaporator  and  form  a  pool 
under the  veh icle.  This  is  normal  and  not  an  indication  of  leaks! 
At  low  outs ide  temperatures,  the  fan  automatically  switches  to a 
higher  speed  when  the  coolant  reaches  a sufficient  temperature 
except  in the  defroster  position. 
When  starting  with  full  throttle,  the  compressor  of the  automatic 
climate  control  system  is  temporarily  switched  off to  achieve  full 
engine  power. 
T o  ensure  engine  cooling  when  the  engine  is  under an  extreme  load, 
the  compressor  is switched  off  at  h igh  coolant  temperatures. 
Pollutant  filter 
The  pollutant  filter  (particle  filter)  ensures  that  impurities  in the 
outs ide  a ir (e.g.  dust,  pollen)  and  odors  are significantly  reduced  or 
stopped.  The  air  is also  filtered  in recirculation  mode. 
Th e  pollutant  filter  e lement  must  be  changed  at  the  intervals speci
fied  in the  service  plan  so  that the  performance  of  the  automatic 
climate  control  system  is  not  impaired. 
If  the  effect iveness  of  the filter  decreases  premat urely  due  to  opera
tion  of  the vehicle  in areas  with  significant  pollution,  the  filter 
element  must  be  changed  between  the  specified  service dates. 
Key  recognition 
The current  climate  control  settings  are  automatically  stored and 
assigned  to  the  key  being  used. The settings  assigned  to  the  key are 
restored  automatically  when the vehicle  is started.  These  settings  are 
different  when  the  power  top  is open  or  closed.  Each driver  can  use 
his  or  her  preferred  settings  witho ut  having  to man ually  adjust  them 
when  using  their  own  key. 
If  another  driver  changes  the  settings  while  using  your  key, your 
prefer red  sett ings  will be  erased. 
Energy  management 
To  prevent  the  battery  from  be ing  discharged  and  to  restore the 
balance  of  energy,  components  which  require  large  amounts  of 
energy  are  temporarily  cut  back  or switched  off=> 
page 247. Heating 
systems  in partic ular  require  a great  dea l of  energy.  If you  notice,  for 
example,  that  the rear  window  heater is not  heating , the n it has  been 
temporarily  reduced  or  switched  off  by 
energy  management . These 
systems  are available  again  as  soon  as  the energy  balance  has  been 
restored.  .,,_  

Warm  and  cold 
In recirculat ion mode,  air  is drawn  from  the  vehicle  interior,  filtered 
and  recirculated.  We  recommend  selecting  recirculation  mode  under 
the  following  conditions: 
When  driving  through  a  tunnel or  in a  traffic  jam  so  that  exhaust 
fumes  and  odors cannot  enter  the  vehicle  interior . 
& WARNING 
You should  not  use the  recirculation  mode for  an extended  period 
since no fresh  air  is drawn  in.  With  the  air-conditioning  switched 
off,  the windows  can fog  up,  which  increases the  risk of  an

Economical  use  of  the  climate  control  system  helps  save 
fuel. 
When  the  climate  control  system  is working  in cooling  mode, 
engine  performance  is  reduced  and  fuel  consumption  is 
affected.  To keep  the  time  the climate  control  system  is on  as 
short  as  possible,  you  should  do  the following : 
- To  save  fuel,  turn  off  cooling  mode  by  pressing  the  [AC] 
button  (indicator  light  goes  out). 
- In  addition,  if you  open  the  window  while  driving,  turn  off  cooling  mode  by  pressing  the 
[AC] button  (indicator  light 
goes  out). 
- If  the  vehicle  is  extremely  hot  due  to the  heat  of  the  sun, 
briefly  open  doors  and  windows. 
 For the  sake of the  environment 
When  you  save  fuel,  you  reduce  emissions  from  the  vehicle. • 
App lies  to  veh ic les:  with  del uxe  automatic  climate control 
Automatic  recirculation 
An  air quality  sensor  detects  increased  concentrations  of 
pollutants  in  the  outside  air and  automatically  switches 
to  recirculation  mode. 
The  basic  climate  control  settings  can  be adjusted  in  the 
radio  or 
MMI*. 
- Select:  Function  button [CAR]> Climate  control  switch. 
We  recommend  that you  always  keep  automatic  recirculation  ON to 
prevent  polluted  outside  ai r from  entering  the  vehicle  interior. 
If the 
air quality  sensor located  in the climate  control  system  detects 
polluted  outside  air,  the  sensor  decides  whether  the  air  pollution  can 
be  reduced  by the  factory-installed  pollutant  filter  or  whether  it is 
necessary  to  switch  to  recirculation . With  heavy  concentrations  of 
pollutants,  the  climate  control  system  is switched  automatically  to 
recirculation  mode  and  the  supply  of  outside  air  is  blocked . As soon 
as  the  concentration  of  pollutants  in the  outside  air drops,  fresh  air  is 
supplied  to the  vehicle  interior again. 
In  the  event  tha t the  windows  fog  up  during  au tomatic  recircula tion, 
press  the[@]  button  immediately. 
Under  certain  operating  conditions,  automatic  recirculation  is 
switched  off  automatically.  When  outside  temperatures  are  below 
about  SO 
°F ( + 10 °(), automatic  recirculation  is  limited  to 
30  seconds.  When  outside  temperatures  are  below  about  30 
°F (-
1 °(), automatic  recirculation  is  limited to 15  seconds .•
