Air conditioning system
Additional to the heating and
ventilation system, the air
conditioning system has:
AC=cooling4=air recirculationCooling (AC)
Operated with the AC button and
functional only when the engine and
fan are running. LED illuminates in
the button when activated.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is above a
specific level. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Notice
Air conditioning performance is
reduced when ECO mode has been
activated 3 108.
Air recirculation system 4
Operated with the 4 button. LED
illuminates in the button when
activated.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling, the
air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and avoid the use
of air distribution settings J and V.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
■ Cooling AC on.
■ Air recirculation system 4 on.
■ Set air distribution control to M.
