2009 HONDA ODYSSEY engine mount

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.
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, the pointer
may rise to the upper zone. If it
reaches the red (hot) mark, pull
safely to the side of the road. For
instructions and precautions on
checking the engine’s cooling
system, see page .477

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging

If the engine is lef t idling f or an
extended period, do not use the
seat heaters, even on the LO
setting. It can weaken the battery,
causing hard starting.
Use the HI setting only to heat the
seats quickly, because it draws
large amounts of current f rom the
battery.
Follow these precautions when using
the seat heaters:
In the HI setting, the heater turns off
when the seat gets warm, and turns
back on after the seat’s temperature
drops.
In LO, the heater does not cycle with
temperature change.
Both f ront seats are equipped with
seat heaters. The passenger seat
only has heaters in the seat bottom
because of the side airbag system.
The ignition switch must be in the
ON (II) position to use them. The
seat heater switches are located on
the dashboard above the center
pocket. Push the top of the switch,
HI, to rapidly heat up the seat.
After the seat reaches a comfortable
temperature, select LO by pushing the bottom of the switch. This will
keep the seat warm.

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 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 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
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 informa-
tion.

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.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.
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
Honda parts or their equivalent.
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.
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.
