It is possible to activate air purification manually from the center display, but the function is also started automatically when preconditioning has finished.
The function uses the ventilation system to blow fresh air into the passenger compartment and then circulates the air through the climate system's passenger compartment air filter.
The amount of small particulates (PM2.5) in the passenger compartment can be monitored in the Volvo Cars app during the pre-cleaning cycle.
