catalytic converter Acura TSX 2007 Owner's Manual

This shows how much fuel you
have. It may show slightly more
or less than the actual amount.
The needle returns to the
bottom after you turn off the
ignition.
This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, such as
very hot weather or a long period of
uphill driving, the pointer may rise to
the upper zone. If it reaches the red (Hot) mark, pull saf ely to the side of
the road. See page f or
instructions and precautions on
checking the engine’s cooling
system.

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.
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 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 moonroof and the
windows are closed.
Turn of f the lights.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Lockthedoorswiththekeyorthe

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.

The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion. 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
quality parts may increase the
emissions f rom your vehicle.
The exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
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 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.
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.2

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.
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.
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 Acura part
or its equivalent.
Keep the engine well maintained.
Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.
