Filter, Cabin Air: Description
All vehicles are equipped with a cabin air filter (1) that helps purify the outside air entering the HVAC housing. The filter is mounted in the engine compartment, inside of the fresh air inlet housing of the heating-A/C system.
The filter should be replaced at least every 20, 000 km (12, 000 miles) or each year and checked if heating-A/C system performance seems lower than expected. The cabin air filter is labeled with "REAR OF VEHICLE" and an arrow (2) to indicate air flow direction through the filter.
