Heating and Cooling

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 off,
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 for the heating and cooling system are at
the base of the windshield. Keep
these clear of leaves and other
debris.

Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page 58) when driving in stop-and-go
traffic or climbing a long, steep hill. If it moves near the red zone, turnoff the A/C until the gauge reads
normally.

These settings direct all the air flow to the defroster vents at the base of
the windshield and the side windowdefroster vents. The air flow 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 safety, make sure you have a
clear view through all the windows
before driving away. To Turn Everything Off
To shut off the system temporarily,
turn the fan speed and temperature
control dials all the way to the left.
You should shut the system completely off only for the first few
minutes of driving in cold weather,
until the engine coolant warms up enough to operate the heater. Keep
the fan on at all other times so stale air does not build up in the interior.

Cooling System

If the coolant level in the reserve
tank is at or below the MIN line, add coolant to bring it up to the MAX line.Inspect the cooling system for leaks.
This coolant should always be a mixture of 50 percent antifreeze and
50 percent water. Never add straight
antifreeze or plain water. Always use Genuine Honda
Antifreeze/Coolant. If it is not
available, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure it
is a high-quality coolant
recommended for aluminum engines.However, continued use of any non-
Honda coolant can result in
corrosion, causing the cooling system to malfunction or fail. Have
the cooling system flushed and
refilled with Honda antifreeze/
coolant as soon as possible.
If the reserve tank is completely
empty, you should also check the coolant level in the radiator.

Adding Engine Coolant

RESERVE TANK
Removing the radiator cap

while the engine is hot can
cause the coolant to spray out,
seriously scalding you.

Always let the engine and radiator cool down before

removing the radiator cap.Main Menu Table of Contents s t

Cooling System

1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counter- clockwise, without pressing downon it, until it stops. This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by pushing down and turningcounterclockwise.
4. The coolant level should be up to
the base of the filler neck. Addcoolant if it is low.
5. Put the radiator cap back on. Tighten it fully.
6. Pour coolant into the reserve tank. Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your car's cooling
system. They may not be compatible
with the coolant or engine compo-
nents.
