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.For the f irst 8,000 miles (12,800 km)
after the Maintenance Required
Indicator is reset, it will come on f or
two seconds when you turn the
ignition switch to ON (II).
This indicator reminds you that it is
time to take your vehicle in for the
vehicle’s scheduled maintenance
under normal driving conditions. The
indicator does not ref lect severe
maintenance intervals.
Ref er to the Maintenance Schedule

Conditions on page (4-cylinder
models) or page (6-cylinder
models).

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.
Check the indicator on the
instrument panel to verif y that the
security system is set.
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.
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.

If you are planning to take your
Honda outside the U.S. or Canada,
contact the tourist bureaus in the
areas you will be traveling in to f ind
out about the availability of unleaded
gasoline with the proper octane
rating.
If unleaded gasoline is not available,
be aware that using leaded gasoline
in your Honda will af f ect perf or-
mance and fuel mileage, and damage
its emissions controls. It will no
longer comply with U.S. and
Canadian emissions regulations, and
will be illegal to operate in North
America. To bring your vehicle back
into compliance will require the re-
placement of several components,
such as the oxygen sensors and the
three way catalytic converter. These
replacements are not covered under
warranty.

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 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 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.
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 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 tuned-up.
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 com-
bustible materials that come near it.
Parkyourvehicleawayfromhigh
grass, dry leaves, or other f lamma-
bles. 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.
