The dust and pollen f ilter is located
behind the glove box.
The dust and pollen f ilter removes
pollen and dust that is brought in
f rom the outside through the heating
andcoolingsystem.
This f ilter should be replaced 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 f rom industry and
diesel-powered vehicles. Replace it
more of ten if air f low f rom the
heating and cooling system becomes
less than usual.
Open the glove box.
To replace it: Push the stop on the right side of
the glove box to detach it from the
glove box.
Pivot the glove box out of the way.

Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereisproba-
bly something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (Seeon page .)
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the car from
a booster battery (see page ). In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Are you using the proper starting
procedure? Ref er to on page .
Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly. Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page .

By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged
to keep the engine running. Drive to
a service station or garage where
you can get technical assistance.
Immediately turn of f all electrical
accessories: radio, heater, A/C, rear
def ogger, cruise control, etc. Try not
to use other electrically-operated
controls such as the power windows.
Keep the engine running and take
extra care not to stall it. Starting the
engine will discharge the battery
rapidly.
This indicator should come on when
the ignition switch is ON (II), and go
out af ter the engine starts. If it
comes on brightly when the engine
is running, it indicates that the
charging system has stopped
charging the battery.

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your car.
Leave the blown fuse in that
circuit and have your car checked
by a qualif ied mechanic.
If you cannot drive the car without
f ixing the problem, and you do not
have a spare fuse, take a fuse of the
same rating or a lower rating f rom
one of the other circuits. Make sure
youcandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio). If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.
Look f or a burned wire inside the
f use. If it is burned, replace it with
oneof thesparefusesof thesame
rating or lower.
Check the smaller f uses in the
under-hood f use box and all the
fuses in the interior fuse box by
pulling out each f use with the f use
puller provided in the under-hood
fuse box. 5.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a replace-
ment f use with the proper rating f or the
circuit, install one with a lower rating.

If you decide to tow your car with all
f our wheels on the ground, make
sure you use a properly-designed and
attached tow bar. Prepare the car for
towing as described above, and leave
the ignition switch in Accessory (I)
so the steering wheel does not lock.
Make sure the radio and any items
plugged into the accessory power
socket are turned of f so they do not

The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in Accessory (I), and
make sure the steering wheel turns
f reely bef ore you begin towing.Trying to lif t or tow your car by the
bumpers will cause serious damage.
The bumpers are not designed to

The emissions control systems are
covered by warranties separate f rom
the rest of your car. Read your
warranty manual f or more inf orma-
tion.
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
genuine Honda replacement parts or
their equivalent f or repairs. Using
lowerqualitypartsmayincreasethe
emissions f rom your car.
The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Engine Control Module (ECM)
or 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 operat- ing conditions.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO and NOx produced.
The exhaust emissions controls
include f our systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Three Way
Catalytic Converter. These four
systems work together to control the
engine’s combustion and minimize
the amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems. 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 ), dinitrogen
(N ), and water vapor.
