Instruments and controls
To reduce the temperature quickly, first use the maximum air speed. Later, the air
speed can be reduced.
Make sure that neither you nor the passengers feel any direct cold or draught. Do
not aim the air vents directly at the body.
Make sure that the temperature difference between the inside and outside of the
cabin does not exceed 5 to 6°C when you leave the cabin. You are therefore
advised to switch off the air conditioning towards the end of the journey.
Remember that the air conditioning consumes engine power and so increases fuel
consumption.
Regularly (once a month) switch on the air conditioning briefly, even if cooling is not
required (for example in winter). This prevents damage to the system (including
compressor blockage).
Recirculation mode
The supply of fresh outside air can be almost fully shut off. This may be desirable to
prevent undesired odours from penetrating into the cabin, for example.
Switch on the recirculation for short periods only to prevent the air quality from
degrading and moisture from increasing.
Using the cabin air recirculation
Switch on the air recirculation by pressing key (13). The key icon turns green.
Recirculation is switched on. The supply of outside air is almost fully shut off. The air in
the cabin is recirculated in the cabin.
The supply of outside air can be almost fully shut off using the
recirculation mode key (13).
De-fog mode
The de-fog mode is intended to clear (de-fog and de-ice) the windows as quickly as
possible.
Using the de-fog mode
Switch on the de-fog mode by pressing key (12). The key icon turns green.
Activation of the de-fog mode results in the following:
the air is directed to the windscreen (100%)
the temperature setting is set to maximum
the fan speed is increased to maximum
the recirculating mode is switched off (100% fresh air drawn in)
the air conditioning system is activated.
