Heating and Cooling

If the interior is very warm from
being parked in the sun, you can cool it down more rapidly by setting up
the controls this way:
1. Start the engine.
2. Turn on the A/C by pressing the button. Make sure the tempera-
ture control lever is all the way to
the left.
3. Set the fan to maximum speed.
4. Open the windows partially. Select and Fresh Air mode.
When the interior has cooled down to a more comfortable temperature,close the windows and set the
controls as described for normal
cooling. Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page 57) 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.

To Heat

To warm the interior: 1. Start the engine. 2. Select and Fresh Air mode.
3. Set the fan to the desired speed.
4. Adjust the warmth of the air with
the temperature control lever.

4. Adjust the temperature control
lever so the mixture of heated and
cooled air feels comfortable.
This setting is suitable for all driving conditions whenever the outside
temperature is above 32°F (0°C).

Heating and Cooling

To remove exterior frost or ice from the windshield and side windowsafter the vehicle has been sitting out
in cold weather:
1. Start the engine.
2. Select

When you select the
system automatically switches to
Fresh Air mode and turns on the
A/C.
3. Switch the fan and temperature controls to maximum.
To rapidly remove exterior frost or ice from the windshield (on very colddays), first select the Recirculation
mode. Once the windshield is clear, select the Fresh Air mode to avoid
fogging the windows. 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
underneath 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, slide the fan speed and temperature
control levers 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

Adding Engine Coolant
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 and50 percent water. Never add straight
antifreeze or plain water. Always use Genuine Honda
antifreeze/coolant. If it is not
available, you may use anothermajor-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.

Maintenance

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.ProCarManuals.comMain 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 turning
counterclockwise.

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.

Cooling System

Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or engine components.
Replacing Engine Coolant
The cooling system should be completely drained and refilled with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only useGenuine Honda antifreeze/coolant.
Draining the coolant requires access
to the underside of the vehicle. Unless you have the tools and
knowledge, you should have this maintenance done by a skilled
mechanic. 1. Slide the heater temperature
control lever to maximum heat.Open the hood. Make sure the
engine and radiator are cool to the
touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. Thecoolant will come out through the
hole in the splash cover.
