2007 HONDA ACCORD HYBRID catalytic converter

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.
The inf ormation display in the
instrument panel shows you the
engine oil lif e and maintenance
service items when the ignition
switch is in the ON (II) position. This
inf ormation helps to keep you aware
of the periodic maintenance your
vehicle needs f or continued trouble-
f ree driving. Ref er to page f or
more inf ormation.Your vehicle’s onboard diagnostic
system will detect a loose or missing
f uel f ill cap as an evaporative system
leak. The f irst time a leak is detected
a ‘‘CHECK FUEL CAP’’ message
appears on the information display.
Turn the engine of f , and conf irm the
f uel f ill cap is installed. If it is, loosen
it, then retighten it until it clicks at
least once. The message should go
off after several days of normal
driving once you tighten or replace
the f uel f ill cap. To scroll to another
display, press the select/reset knob.
The ‘‘CHECK FUEL CAP’’ message
will appear each time you restart the
engine until the system turns the
message of f .
If the system still detects a leak in
your vehicle’s evaporative emissions
system, the malf unction indicator
lamp (MIL) comes on. If the f uel f ill
cap was not already tightened, turn
the engine of f , and check or
retighten the f uel f ill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go of f ,
have your vehicle inspected by a
dealer. For more inf ormation, see

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.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.If the vehicle is f acing uphill, turn
the front wheels away from the
curb.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb.
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.
Make sure the moonroof and the
windows are closed.
Check the indicator on the
instrument panel to verif y that the
security system is set. Lockthedoorswiththekeyorthe
remote transmitter. Place any packages, valuables, etc.,
in the trunk or take them with you. Turn of f the lights.
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 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 f rom the crankcase and
evaporative emissions control
systems.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
quality parts may increase the
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 informa-
tion.
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)
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 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 ), nitrogen
(N ), and water vapor.

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.
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. 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.
