Automatic climate control ECC with Interior Air Quality system (option)
Multifilter with
Air quality sensor (option)
Some cars are equipped with a multifilter and
air quality sensor. The multifilter separates
gases and particles, reducing the volume of
odours and contaminants entering the car. The
air quality sensor detects increased levels of
contaminants in the outside air. When the air
quality sensor detects contaminated outside
air, the air intake is closed and the air inside the
compartment is recirculated. The multifilter
also cleans the air recirculating in the compart-
ment.
When the air quality sensor is connected, the

Points to remember:
·
Make it a rule to have the air quality sensor
activated at all times.
·
Recirculation is limited in cold climates to
avoid misting.
·
In the event of misting, you should
disconnect the air quality sensor.
·
In the event of the windows misting up
you can also use the windscreen and side
window defroster functions. See next page.
·
The recommended interval for changing the
combination filter is at every other
scheduled service. The multifilter may need
to be changed more often if you drive in
heavily polluted environments.
