Refrigerant in the A/C system
The sticker in the engine compartment provides
information about the type and amount of refrig-
erant used in the vehicle’s A/C system. The stick-
er is located in the front section of the engine
compartment or at the front or back of the hood.
A sensor detects the particulate matter concen-
tration (PM2.5) outside and inside the vehicle.
The detected values are displayed as the air qual-
ity index (AQI) on a colored scale 1 . A value in
the green range indicates very good air quality.
Symbol Meaning
The system displays the approximate values,
which may differ from actual conditions. In cer-
