2003 HONDA CR-V 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
in the button lights when the A/C is
on.This button controls the source of
the air going into the system. When
the indicator in 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).
This button turns the rear window
def ogger on and of f (see page ).Use the MODE control dial to select
the vents the air flows from. Some
air will f low f rom the dashboard
vents in all modes.

Set the f an to the desired speed.
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.
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. 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.
The f low-through ventilation system
draws in outside air, circulates it
through the interior, then exhausts it
through vents near the tailgate.1.

These settings direct all the air f low
to the defroster vents at the base of
the windshield and the side window
def roster vents. The air f low will get
warmer and clear the windows faster
as the engine warms up. You can
close the side vents with the dial
beside each vent. This will send
more warm air to the windshield
defroster vents.
For saf ety, make sure you have a
clear view through all the windows

Always maintain your vehicle accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
The condition of your vehicle and
your driving habits are the two most
important things that affect the fuel
mileage you get.
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.
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.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
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. 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.
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. 245

µµAlways drive
slower than you would in dry
weather. It takes your vehicle longer
to react, even in conditions that may
seem just barely damp. Apply
smooth, even pressure to all the
controls. Abrupt steering wheel
movements or sudden, hard appli-
cation of the brakes can cause loss of
control in wet weather. Be extra
cautious f or the f irst f ew miles
(kilometers) of driving while you
adjust to the change in driving
conditions. This is especially true in
snow. A person can f orget some
snow-driving techniques during the
summer months. Practice is needed
to relearn those skills.
Exercise extra caution when driving
in rain af ter a long dry spell. Af ter
months of dry weather, the f irst
rains bring oil to the surf ace of the
roadway, making it slippery. Being able to see
clearly in all directions and being
visible to other drivers are important
in all weather conditions. This is
more dif f icult in bad weather. To be
seen more clearly during daylight
hours, turn on your headlights.
Inspect your windshield wipers and
washers f requently. Keep the wind-
shield washer reservoir f ull of the
proper f luid. Have the windshield
wiper blades replaced if they start to
streak the windshield or leave parts
unwiped. Use the def rosters and air
conditioning to keep the windows
f rom f ogging up on the inside (see
page ).
Rain, f og, and snow conditions re-
quire a dif f erent driving technique
because of reduced traction and
visibility. Keep your vehicle well-
maintained and exercise greater
caution when you need to drive in
bad weather. The cruise control
should not be used in these condi-
tions. 134
