The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from under the vehicle.

saving reasons. Activated cooling
may inhibit Autostops.

mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air

compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate s.
Maximum cooling

air can disperse quickly.
