This f ilter removes the dust and

system.
Have your dealer replace this filter
when this service is indicated by a
maintenance message on the
inf ormation 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 f low f rom
theclimatecontrolsystembecomes
less than usual.
If you remove a f loor mat, make sure

If you use a non-Honda f loor mat,
make sure it f its properly and that it

anchors. Do not put additional f loor
mats on top of the anchored mat.
Make sure the rear f loor mats are
properly positioned. If not, the f loor
mat will interf ere with the seat
operation and make the f ront
passenger’s weight sensors
inef f ective.
When cleaning or replacing, turn the
knob counterclockwise to unhook
the floor mat. The driver’s f loor mat that came
with your vehicle hooks over the
f loor mat anchors. To lock each
anchor, turn the knob clockwise.
This keeps the f loor mat f rom sliding
f orward and possibly interf ering with
the pedals.

If you store the spare tire f ace down, it
will be damaged and need to be
replaced.
Always ensure that the spare tire holder
is installed onto the hook and the
holder is then completely raised into
place. If the holder is lef t down, it will
be damaged during driving and will
need to be replaced.

The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate
from the rest of your vehicle.
Read your warranty manual for
more inf ormation.
The PGM-FI system uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
f uel to inject under all operating
conditions. This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.
The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These f our systems work
together to control the engine’s
combustion and minimize the
amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.
