Floor Mats, Dust and Pollen Filter
Floor Mats
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.
158
If you use a non-Honda floor mat,
make sure it fits properly and that it
can be used with the floor mat
anchor. Do not put additional floor
mats on top of the anchored mat.
Dust and Pollen Filter
This filter removes the dust and
pollen that is brought in from the
outside through the heating and
cooling 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 flow from the heating and
cooling system becomes less than
usual.
