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 and the
windows are closed.
Turn of f 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 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.
If the vehicle is f acing uphill, turn
the front wheels away from 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.
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 you are unable to stop the
engine normally when the vehicle is
parked (in the Park position on the
automatic transmission models),

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 from the crankcase and
evaporative emissions control
systems.The emissions control systems are
designed and certif ied to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura 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 from
the rest of your vehicle. Read
your warranty manual for more
information.
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. It then controls how much f uel to inject
under all operating conditions.
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 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.

Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly. Keep the engine well maintained.
The three way catalytic converters
contain precious metals that serve as
catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converters are ref erred
to as three-way catalysts, since they
act on HC, CO, and NOx.
Replacement units must be original
Acura parts or their equivalent.
The three way catalytic converters
must operate at a high temperature
for the chemical reactions to take
place. They can set on f ire any
combustible materials that come
near them. Park your vehicle away
f rom high grass, dry leaves, or other
f lammables.
Defectivethreewaycatalytic
converters contribute to air pollution,
and can impair your engine’s
perf ormance. Follow these
guidelines to protect your vehicle’s
three way catalytic converters.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converters
inef f ective.
