Gauges

Fuel Gauge
This shows how much fuel you have. It is most accurate when the car is on
level ground. It may show slightlymore or less than the actual amount
when you are driving on curvy or hilly roads. The gauge stays at the same fuel
level reading after you turn off the
ignition. When you add fuel, the
gauge slowly changes to the new
reading after you turn the ignitionswitch back ON (II). Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the pointer should rise
from the bottom white mark to about
the middle of the gauge. In severe driving conditions, such as very hot
weather or a long period of uphill driving, the pointer may rise to the
upper blue zone. If it reaches the red (Hot) mark, pull safely to the side of
the road. Turn to page 229 for
instructions and precautions on checking the engine's cooling

system.

Heating and Cooling

Vent Controls
You can adjust the direction of the
air coming from the dashboard vents
by moving the tab in the center of each vent up-and-down and side-to-
side.
The vents in the corners of the
dashboard can be opened and closed
with the dials next to them. How to Use the System
This section covers how to set up the system controls for ventilation,
heating, cooling, dehumidifying, and defrosting.
The engine must be running for 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 before you feel warm air
coming from the system.
The air conditioning does not rely on engine temperature.

To Cool with A/C

1. Turn on the A/C by pressing the button. The light in the buttonshould come on when a fan speed
is selected.
2. Make sure the temperature control dial is all the way to the left. 3. Select
4. If the outside air is humid, select
Recirculation mode. If the outsideair is dry, select Fresh Air mode.
5. Set the fan to the desired speed.
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 dial 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 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.

Heating and Cooling

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

Replacing Engine Coolant

The cooling system should be completely drained and refilled with
new coolant according to the timeand distance recommendations in
the maintenance schedule. Only use Genuine Honda Antifreeze/Coolant.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance done by a skilled mechanic. 1. Turn the ignition ON (II). Turnthe temperature control dial to
maximum heat. Turn off the
ignition and remove the key. Open
the hood. Make sure the engineand radiator are cool to the touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. The
coolant will come out through the
hole in the splash cover.
(U.S.: Si model, Canada: SiR model)
Remove the drain bolt and washer
from the engine block.

If Your Engine Overheats
The pointer of your car's tempera- ture gauge should stay in the mid-range under most conditions. It may
go higher if you are driving up a long steep hill on a very hot day. If it
climbs to the red mark, you should
determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine. Your car can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only

indication may be the temperature

gauge climbing to or above the red
mark. Or you may see steam or spray coming from under the hood.
In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in Neutral orPark and set the parking brake.
Turn off the heating and cooling system and all other accessories.
Turn on the hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turnoff the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading (climbing a long, steep hill on a
hot day with the A/C running, for
example), the engine should start
to cool down almost immediately. If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.

Taking Care of the Unexpected

NOTICE

Steam and spray from an

overheated engine can

seriously scald you.
Do not open the hood if steam
is coming out.Main Menu Table of Contents s t

If Your Engine Overheats
4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot, so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 241).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page112). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check-
ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes off. 10.Start the engine and set the
temperature control dial to
maximum. Add coolant to the
radiator up to the base of the filler
neck. If you do not have the
proper coolant mixture available,
you can add plain water.Remember to have the coolingsystem drained and refilled with
the proper mixture as soon as you
can.

11.Put the radiator cap back on tightly. Run the engine and watchthe temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See Emergency
Towing on page 241.)
12.If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the MAX mark. Put the cap back on

tightly.

Taking Care of the Unexpected
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
