2003 HONDA ODYSSEY air conditioning

Proper use of the Heating and
Cooling system can make the
interior dry and comf ortable, and
keep the windows clear f or the best
visibility.
Turning this dial clockwise increases
the f an’s speed, which increases air
flow.
Turning this dial clockwise increases
the temperature of the air flow.
This button turns the air condi-
tioning ON and OFF. The indicator
above the button lights when the
A/C is on.This button controls the source of
the air going into the system. When
the indicator above this button is lit,
air f rom the vehicle’s interior is sent
through the system again (Recircula-
tion mode). When the indicator is off,
air is brought in f rom outside the
vehicle (Fresh Air mode).
With this dial, you can adjust the
rear A/C unit heating, cooling, and

This section covers how to set up the
system controls f or ventilation,
heating, cooling, dehumidif ying, and
def rosting.
The engine must be running f or the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes bef ore you f eel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.
It is best to leave the system in Fresh
Air mode under almost all conditions.
Keeping the system in Recirculation
mode, particularly with the A/C of f ,
can cause the windows to fog up.
Switch to Recirculation mode when
you are driving through smoky or
dusty conditions, then switch back to
Fresh Air mode when the condition
clears.The outside air intakes f or the
heating and cooling system are at
the base of the windshield. Keep
these clear of leaves and other
debris.
The f low-through ventilation system
draws in outside air, circulates it
through the interior, then exhausts it
through vents near the rear side
panels.
Turn the temperature control dial
all the way to the lef t.
Make sure the A/C is of f .

When the interior has cooled down
to a more comf ortable temperature,
close the windows and set the
controls as described f or normal

on the engine. Watch the engine
coolant temperature gauge (see page
) when driving in stop-and-go

If it moves near the red zone, turn
of f the A/C until the gauge reads
normally.

The condition of your vehicle and
your driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your vehicle accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your vehicle uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cto
cut down on air conditioning use.
Use the f low-through ventilation
when the outside air temperature is
moderate.
In winter, the build-up of snow on
your vehicle’s underside adds weight
and rolling resistance. Frequent
cleaning helps your f uel mileage and
reduces the chance of corrosion. An important part of that mainte-
nance is the (see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly. 295
