2000 HONDA PRELUDE cooling

Carbo
n Monoxid e Hazar d

Your car's exhaust contains carbon monoxide gas. You should have no
problem with carbon monoxide entering the car in normal driving if
you maintain your car properly. Have the exhaust system inspected
for leaks whenever:
The car is raised for an oil change. You notice a change in the sound
of the exhaust.
The car was in an accident that may have damaged the underside.

High levels of carbon monoxide can
collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the engine only long enough to move the
vehicle out of the garage. With the trunk lid open, air flow can
pull exhaust gas into your car's
interior and create a hazardouscondition. If you must drive with the
trunk lid open, open all the windows and set the heating and coolingsystem as shown below.
If you must sit in your parked car, even in an unconfined area, with the
engine running, adjust the heating and cooling system as follows:
1. Select the Fresh Air mode. 2. Select the mode.
3. Turn the fan on high speed.
4. Set the temperature control to a
comfortable setting.
Drive r an d Passenge r Safet y

Carbon monoxide gas is toxic.
Breathing it can cause
unconsciousness and even kill
you.
Avoid any enclosed areas or
activities that expose you to
carbon monoxide.

Gauges

Fue l Gaug e
This shows how much fuel you have. It is most accurate when the car is on
level ground. It may show slightly more 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 theignition. When you add fuel, the
gauge slowly changes to the new
reading after you turn the ignition switch back ON (II). Temperatur
e Gaug e
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 severedriving conditions, such as very hot
weather or a long period of uphill driving, the pointer may rise to near
the upper white mark. If it reaches
the red (Hot) mark, pull safely to the side of the road. Turn to page 246 for
instructions and precautions on
checking the engine's cooling
system.

Ven t Control s
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 underneath them. Ho
w to Us e th e Syste m
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.

g an d Coolin g

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.
Ventilation

The flow-through ventilation system draws in outside air, circulates it
through the interior, then exhausts it
through vents near the rear window. 1. Slide the temperature control lever
all the way to the left.
Make sure the A/C is off. 2. Select and Fresh Air mode.
3. 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 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 59 ) when driving in stop-and-go
traffic or climbing a long, steep hill.
If it moves near the red zone, turn off 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.
To Heat and Dehumidify with Air

Conditioning

Air conditioning, as it cools, removes moisture from the air. When used in
combination with the heater, it
makes the interior warm and dry.
1. Switch the fan on.
2. Turn on the air conditioning. 3. Select and Fresh Air mode.
4. Adjust the temperature control
lever so the mixture of heated andcooled air feels comfortable.
This setting is suitable for all driving conditions whenever the outsidetemperature is above 32°F (0°C).

Towin
g a Traile r

Additional Trailer Equipment
Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don't,
you should install special mirrors if
you cannot clearly see behind you, or if the trailer creates a blind spot.
Ask your trailer sales or rental agency if any other items are
recommended or required for your

towing situation.
Pre-To
w Checklis t
When preparing to tow, and before driving away, be sure to check the

following:
The vehicle has been properly
serviced, and the tires, brakes,
suspension, and cooling system
are in good operating condition.
All weights and loads are within limits (see pages 160 and 161). The hitch, safety chain, and any
other attachments are secure. All items on and in the trailer are
properly secured and cannot shift
while you drive. The lights and brakes on your
vehicle and the trailer are workingproperly. Your vehicle tires and spare are
properly inflated (see page 206), and the trailer tires and spare are
inflated as recommended by the
trailer maker.
