2000 Acura RL catalytic converter

Parkin
g

Always use the parking brake when
you park your car. 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
car may roll if it is parked on an
incline.
Set the parking brake before you put
the transmission in Park. This keeps
the car 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 car is facing uphill, turn the
front wheels away from the curb.
If the car is facing downhill, turn the
front wheels toward the curb.
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. Parkin
g Tip s
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 with the key or the
remote transmitter. Check the
indicator on the driver's door to
verify that the security system is set. 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.

If you are planning to take your
Acura outside the U.S. or Canada, contact the tourist bureaus in the
areas you will be traveling in to findout 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 Acura will affect perfor-
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 car back into compliance will require the replace-
ment of several components, such as
the oxygen sensors and the three
way catalytic converter. These re-
placements are not covered under
warranty.

Emission
s Control s

Exhaus t Emission s Control s
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 areseparate 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 Powertrain Control Module (PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much fuel to inject under all operat-
ing conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amountof 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. Throughchemical reactions, it converts HC,
CO, and NOx in the engine's exhaust
to carbon dioxide (CO 2), dinitrogen
(N 2), and water vapor. Replacemen
t Part s

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 Acura replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your car.
The emissions control systems are covered by warranties separate from
the rest of your car. Read your
warranty manual for more informa-
tion.

Thre
e Wa y Catalyti c Converte r
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 Acura 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 car away from high grass,dry leaves, or other flammables. A defective three way catalytic
converter contributes to air pollution,
and can impair your engine's per-
formance. Follow these guidelines to protect your car'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 car diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not running properly.
