Notes on climate control
An interior air filter in combination with the prefilter
in the engine compartment must always be
used so that the air conditioning system, pollution
level monitoring and the air filtration work
correctly. Make sure that the filter is installed
correctly and the filter housing in the engine
compartment is closed correctly using the cap
and always tightly sealed when in operation...
Switching climate control on/off
To switch on: set the
airflow to level 1 or
higher using the button.
To switch off: set the
airflow to level 0 using
the button.
If climate control is switched off, the windows
may fog up more quickly. Switch climate control
off only briefly...
