Carbon Monoxide Hazard

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 under-

side.
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 car out of the garage.
With the trunk lid open, air flow
can pull exhaust gas into the trunk.
This can get into your car's interior
and create a hazardous condition. If
you must drive with the trunk lid
open, open all the windows and set
the heating and cooling system as
shown in the next column. 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.
Driver and Passenger Safety

Carbon monoxide gas is toxic.
Breathing it can cause uncon-
sciousness and can even kill

you.

Avoid any enclosed areas or
activities that expose you to
carbon monoxide.ProCarManuals.comMain Menu Table of Contents s t

Heating and Cooling

This system has full heating,
ventilation, and air conditioning* capabilities. You can adjust the
system controls to mix these in
various combinations to create the desired environment. The air flows
into the interior at three possible
levels, which you can select.
(S model only)
A Genuine Honda air conditioning
system is available from your
dealer. It meets Honda's high
quality standards and is designed to
fit your car. If you purchased your car without air conditioning, it can
be installed at any time. Please
contact your dealer for more
information.
* Air conditioner is optional on S

model.
The direction of airflow from the
vents in the center of the dash-
board and the corner vents in each
door is adjustable. Move the tab in
the center of each vent up-and-

down and side-to-side.

The center, corner and side
defroster vents can be opened and
closed with the dials next to them.
The heating and cooling system

draws air through the exterior
vents at the bottom of the wind-
shield. Keep these vents clear of

leaves and other debris.

How to Use the System
This section covers the best way to
use the system for ventilation, cooling, dehumidifying, defrosting
and heating. In most cases, the
mode and air source selections are
only recommendations. You may
prefer different settings.
Use the Recirculation mode to heat
or cool the interior more quickly, or
to keep out smoke and dust.
Leaving the system in recirculation
mode with the A/C off can cause
the windows to fog up. Switch to
the Fresh Air mode as soon as the
interior reaches a comfortable
temperature or the outside smoky,
dusty condition clears.
The engine must be running for the

heater and air conditioner to pro-

vide hot and cold air. The heater
uses engine coolant to warm the air.

If the engine is cold, it will be sever-

al minutes before you feel warm air

circulating.

The air conditioner does not de-

pend on engine temperature. It can produce cold air almost immedi-

ately.

Controlling Air Flow direction
Air flows into the interior at three
levels: Toward the floor
through the dash vents
toward the windshield and side windows You select the air
flow level or combination of levels
with th

e five mode buttons. Ventilation
Your car has a flow-through
ventilation system. Air enters the car through vents in front of the
windshield. I

t circulates through
the interior then exits through
vents nea
r the rear window. This
system provides fresh air even
when th

e car is standing still. To
bring i

n outside air, select the
Fresh Air mode. Set the fan at a
comfortable speed
.

To Dehumidify and Defog
with A/C

An air conditioner removes mois-
ture from the air as it operates.
You can use it to defog the win-
dows quickly in cool or damp wea-
ther. Used in combination with the
heater, it also makes the interior
warm and dry. This setting is best
for all driving conditions whenever
the outside temperature is above
32°F (0°C).
1. Set the fa n to a medium speed.
2. Tur n
on the air conditioner.
3. Select any desired mode button; is usually best.
4. Adjust the temperature control lever so the mixture of heated
and cooled air is at a comfortable
temperature.
You can defog the side windows more quickly by shutting the
corner vents and opening the side
defroster vents.

Fuel Economy

The condition of your car and your
driving habits are the two most
important things that affect the
fuel mileage you get.

Vehicle Condition

Always maintain your car accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.
An important part of that mainte-
nance is the Periodic Checks
(see page
133). For example an
underinflated tire causes more "rolling resistance," which uses
fuel. It also wears out faster, so check the tire pressure at least

monthly. In winter, the build-up of

snow on your car's underside adds

weight and rolling resistance.

Frequent cleaning helps your fuel

mileage and reduces the chance of

corrosion.
Driving
Habit
s

You can improve fuel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel. Always
drive in the highest gear that al-
lows the engine to run and acceler-
ate smoothly. Depending on traffic
conditions, try to maintain a con-
stant speed. Every time you slow
down and speed up, your car uses
extra fuel. Use the cruise control,
when appropriate, to increase fuel
economy.

A cold engine uses more fuel than a
warm engine. It is not necessary to "warm-up" a cold engine by letting
it idle for a long time. You can
drive away in about a minute, no
matter how cold it is outside. The
engine will warm up faster, and you
get better fuel economy. To cut
down on the number of "cold starts,"
try to combine several short trips
into one. The air conditioner puts an extra
load on the engine which makes it
use more fuel. Turn off the A/C to
cut down on air conditioner use.
Use the flow-through ventilation
when the outside air temperature is moderate.
