5.27.8 AQS (Air Quality System)
The AQS (Air Quality System) blocks the fresh air inlet to prevent
the harmful gases from entering if the concentration of hazardous
gases in air is higher than the specified value.
If the concentrations of hazardous gases go below the specified
values, the system is automatically switched to the fresh air mode.
AQS indicator
At initial engine start-up, the AQS indicator comes on (1) and the
recirculation air indicator comes on (2) for 40 seconds. During this
time, AQS is warmed-up and its function does not work.
If hazardous gases are detected in the outside air in AUTO mode,
the system is switched to recirculation mode. At this time, the AQS
indicator (1) and indicator on the recirculation/fresh air switch (2)
are turned on.
The AQS blocks the intrusion of hazardous gases, such as NO, NO2,
SO2, CO, with concentration higher than the reference value. It
cannot protect the vehicle from odour..
