in your vehicle.
If you use a non-Honda f loor mat,
make sure it f its properly and that it
canbeusedwiththefloormat
anchors. Do not put additional f loor
mats on top of the anchored mat.This f ilter removes the dust and
pollenthatisbroughtinfromthe
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
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 airf low
from the heating and cooling
system/climate control system
becomeslessthanusual.
Make sure the rear f loor mats are
properly positioned. If not, the f loor
mat will prevent the seat operation
and make the front passenger’s
weight sensors inef f ective.

Place the flat tire face down in the
spare tire well.
Remove the spacer cone f rom the
wing bolt, turn it over, and put it
back on the bolt.To remove the spacer cone, squeeze
the tabs on the wing bolt to
disengage it f rom the center of the
spacer cone, then pull the bolt
downward.
To install the wing bolt to the spacer
cone, reverse this procedure.

kit case. Place the tool kit case in
the f lat tire.
Your vehicle’s original tire has a
tire pressure monitoring system

Store the wheel cover or center
cap in the trunk. Make sure it does
not get scratched or damaged.

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) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. Itthen controls how much f uel to inject
under all operating conditions. 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 f rom
the rest of your vehicle. Read your
warranty manual f or more inf orma-
tion.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust emissions controls
includethreeorfoursystems:PGM-
FI, ignition timing control, exhaust
gas recirculation (V6 models), and
three way catalytic converter. These
three or four 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.
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 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.
