This shows how much f uel you have.
It may show slightly more or less
than the actual amount. The needle
returns to the bottom after you turn
of f the ignition.The inf ormation display in the
instrument panel shows you the
engine oil lif e and maintenance
service items when the ignition
switch is in the ON (II) position. This
inf ormation helps to keep you aware
of the periodic maintenance your
vehicle needs f or continued trouble-
f ree driving. Ref er to page f or
more information.
If your f uel cap is loose or missing, a
‘‘CHECK FUEL CAP’’ message will
appear in the inf ormation display. As
soon as it is saf ely possible, turn the
engine of f and check that the f uel
cap is installed. If it is, loosen the cap
and tighten it to at least 1 click.
Although you can use t
he selec t/
r eset kno b to c yc le the fuel c ap
warning o ff o f the display, it will be
displayed ag ain eac h time the eng ine
is started. It will take several days o f
no rmal driving fo r the vehic le to turn
the warning o ff.
If the vehic le o n bo ard diag no stic
system c o ntinues to detec t a

l amp ( M IL) will illuminate. If the
M IL do es no t g

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging
the catalytic converter.

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.
If your vehicle has an automatic
transmission, set the parking brake
bef ore you put the transmission in
Park. This keeps the vehicle f rom
moving and putting pressure on the
parking mechanism in the
transmission.Make sure the moonroof (if
equipped) and the windows are
closed.
Turn of f the lights.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Lockthedoorswiththekeyorthe
remote transmitter.
If your vehicle has a manual
transmission, put it in f irst gear. Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
If the vehicle is f acing uphill, turn
the f ront wheels away f rom the
curb. If your vehicle has a manual
transmission, put it in f irst gear.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb. If your vehicle has a manual
transmission, put it in reverse gear.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
Check the indicator on the
instrument panel to verif y that the
security system is set.

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.
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.
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.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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 three way catalytic converter
contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converter is ref erred to
as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Honda part
or its equivalent.Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter inef f ective.Keep the engine well maintained.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on f ire any
combustible materials that come
near it. Park your vehicle away from
high grass, dry leaves, or other
f lammables. A defective three way catalytic
converter contributes to air pollution,
and can impair your engine’s per-
f ormance. Follow these guidelines to
protect your vehicle’s three way
catalytic converter.
Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.
