variations in the outside temperature and for the effect of direct
sunlight.
The automatic temperature regulation only operates at temperature
settings between +16 °C and +28 °C. If a temperature below +16 °C
is selected, LO appears on the display. If a temperature above +28 °C

reduces engine power and increases fuel consumption. To
ensure that the cooling mode is activated only when really
necessary, please note the following points:
– Switch off the cooling mode by pressing the AC button (LED off) if you wish to save fuel.
– You should also switch off the cooling mode by pressing the AC button (LED off) if you open the windows or the
tilting panorama roof* while driving.
– If the vehicle has heated up after standing in the sun, open the windows and doors for a short time to cool the
vehicle.
For the sake of the environmentBy saving fuel you also reduce the amount of pollutants emitted
from your vehicle.

been temporarily switched off by the power management function,
or regulated to a lower heat output. These systems will be available
again as soon as sufficient electrical power is available.
WARNING
For safety reasons it is important that all the windows are kept
free of ice, snow and condensation . These can cause poor visibility
and lead to an accident. Please fa miliarise yourself with the oper-
ating controls for the air conditioner, including the demist/defrost
functions for the windows.
Caution
•
If you suspect that the air conditioner is damaged, switch it off
to prevent further damage and have the system checked by a quali-
fied workshop.
•
Repairs to the air conditioning system require specialist knowl-
edge and special tools. For this reason, please contact a qualified
workshop if the system is not working properly.Note
•
Keep the air intake slots in front of the windscreen clear of snow,
ice and leaves to ensure unimpaired heating and cooling, and to
prevent the windows misting over.
•
The air from the outlets flows through the passenger compart-
ment and out through the slots at the rear of the vehicle. Do not
cover these slots with cl othing or other objects.
•
The air conditioner operates most effectively with the windows
and the tilting panorama roof* closed. However, if the vehicle has
heated up after standing in the sun for some time, the air inside can
be cooled more quickly by opening the windows for a short time.
