The filter should be replaced more often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be replaced with a new one. Materials used in the cabin The materials used in the cabin have been developed to help minimize the amount of dust and make the cabin easier to keep clean. All floor mats can be easily removed for cleaning. Use car cleaning products recommended by Volvo. See also the information beginning on page 345.

Ensure that the correct type is installed. Interior Air Quality System (IAQS) A multifilter helps reduce gases and particles in the incoming air, thereby reducing the levels of odors and contaminants entering the vehicle. 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 closes and the air inside the passenger compartment is recirculated, i.e. no outside air enters the vehicle. The filter also cleans recirculated passenger compartment air. • Blower speed in automatic mode. • Recirculation timer for passenger compartment air. The incoming air is distributed from a number of different vents in the passenger compartment. Air distribution is fully automatic in AUTO mode. If desired, air distribution can be controlled manually, see page 144. • Automatic rear window defrosting. • The optional Interior Air Quality System (IAQS). The functions can also be returned to factory settings in the menu system. See page 131 for a description of the menu system. NOTE Contact your Volvo retailer for IAQS air filter replacement intervals. 138
