If you remove a floor mat, make sure
to re-anchor it when you put it back
in your vehicle.
If you use a non-Honda floor mat,
make sure it fits properly and that it
can be used with the floor mat
anchors. Do not put additional floor
mats on top of the anchored mat.
Make sure the rear floor mats are
properly positioned. If not, the floor
mat will interfere with the seat
operation and make the front
passenger's weight sensors
ineffective.
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
when this service is indicated by a
maintenance message on the
information display. 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 airflow
from the heating and cooling
system/climate control system
becomes less than usual.
