air conditioning HONDA CR-V 2002 RD4-RD7 / 2.G Owners Manual

Proper use of the Heating and
Cooling system can make the
interior dry and comf ortable, and
keep the windows clear f or 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.

It is best to leave the system in Fresh

Keeping the system in Recirculation

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

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.

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
cutdownonairconditioninguse.
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 difficult 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

The added weight, length, and

techniques.

distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over. Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
If you have an automatic
transmission, use the Over drive

If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in

as this can cause the automatic
transmission to overheat.

Your vehicle’s air conditioning is a
sealed system. Any major mainte-
nance, such as recharging, should be
done by a qualif ied mechanic. You
can do a couple of things to make
sure the air conditioning works
ef f iciently.Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them. 343

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.

Remove the f irst f ilter by pulling it
straight out of the air conditioning
unit. Remove the second f ilter by
sliding it to the lef t, then pulling it
out.Remove the old f ilter f rom the
f ilter case.
Install the new f ilter in the case.
Make sure the ‘‘AIR FLOW’’
arrows on the f ilter and the f ilter
case f ace the same direction.Install the dust and pollen f ilters
into the air conditioning unit.
Make sure the ‘‘AIR FLOW’’
arrows on the f ilter point
downward.
Reinstall the dust and pollen f ilter
cover.
Pivot the glove box up into
position. Reinstall the hooks into
thesidepanelof theglovebox.
Close the glove box.
If you are not sure how to replace
the dust and pollen filters, have them
replaced by your Honda dealer.
