Parking
Always use the parking brake when
you park your vehicle. The indicator on the instrument panel shows that
the parking brake is not fully
released; it does not indicate that the
parking brake is firmly set. Make sure the parking brake is set firmly
or your vehicle may roll if it is
parked on an incline.
If your vehicle has an automatic
transmission, set the parking brake
before you put the transmission in Park. This keeps the vehicle from
moving and putting pressure on the
parking mechanism in the
transmission — making it easier to move the shift lever out of Park
when you want to drive away. If the vehicle is facing uphill, turn
the front wheels away from the curb. If you have a manual transmission,
put it in first gear.
If the vehicle is facing downhill, turn
the front wheels toward the curb. If
you have a manual transmission, put it in reverse gear.
Make sure the parking brake is fully
released before driving away. Driving with the parking brake
partially set can overheat or damage
the rear brakes. Parking Tips
Make sure the moonroof and the
windows are closed.
Turn off the lights. Place any packages, valuables, etc.,
in the trunk or take them with you.
Lock the doors.
Never park over dry leaves, tall
grass, or other flammable
materials. The three way catalytic
converter gets very hot, and could
cause these materials to catch on
fire.

Driving in Foreign Countries
If you are planning to take your
Honda outside the U.S. or Canada,
contact the tourist bureaus in theareas you will be traveling in to find
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 affect perfor-
mance and fuel mileage, and damage
its emissions controls. It will no
longer comply with U.S. andCanadian 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.

Emissions Controls
Exhaust Emissions Controls
The exhaust emissions controls include four systems: PGM-FI,
Ignition Timing Control, ExhaustGas 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 from the crankcase and
evaporative emissions control
systems.
PGM-FI System
The PGM-FI System uses sequential multiport fuel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Engine Control Module (ECM) uses various sensors to determine
how much air is going into the engine. It then controls how much
fuel to inject under all operating conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amount
of HC, CO and NOx produced.
Exhaust Gas Recirculation (EGR)
System
The Exhaust Gas Recirculation (EGR) system takes some of the
exhaust gas and routes it back into
the intake manifold. Adding exhaust
gas to the air/fuel mixture reduces the amount of NOx produced when
the fuel is burned.
Three Way Catalytic Converter
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 (C02), dinitrogen
(
N2), and water vapor.
Replacement Parts
The emissions control systems are designed and certified 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 newGenuine Honda replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your vehicle.
The emissions control systems are covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.

Three Way Catalytic Converter
The three way catalytic converter contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter is referred 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.
The three way catalytic converter must operate at a high temperature
for the chemical reactions to take place. It can set on fire any com-
bustible materials that come near it. Park your vehicle away from high
grass, dry leaves, or other flamma-
bles.
A defective three way catalytic
converter contributes to air pollution,
and can impair your engine's per-
formance. Follow these guidelines to
protect your vehicle's three way
catalytic converter. Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the catalyst metals, making the three
way catalytic converter ineffective. Keep the engine tuned-up. Have your vehicle diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not
running properly.
