Floor Mats, Dust and Pollen Filter Floor Mats If you use non-Honda floor mats, make sure they fit properly and that they can be used with the floor mat anchors. Do not put additional floor mats on top of the anchored mats. Dust and Pollen Filter This filter removes the dust and pollen that is brought in from the outside through the heating and cooling system/climate control system. Have your dealer replace this filter every 30,000 miles (48,000 km) under normal conditions. It should be replaced every 15,000 miles (24,000 km) if you drive primarily in urban areas that have high concentrations of soot in the air, or if the air flow from the heating and cooling system/climate control system becomes less than usual. The floor mats that came with your vehicle hook over the floor mat anchors. This keeps them from sliding forward and possibly interfering with vehicle operation. If you remove a floor mat, make sure to re-anchor it when you put it back in your vehicle. 252
