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.

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.

Before Driving

Before you begin driving your Honda,
you should know what gasoline to use, and how to check the levels of
important fluids. You also need to
know how to properly store luggage or packages. The information in this
section will help you. If you plan to
add any accessories to your car,
please read the information in this section first. Break-in Period.............................. 124

Break-in Period, Gasoline

Break-in Period

Help assure your car's future
reliability and performance by paying extra attention to how you drive
during the first 600 miles (1,000 km).
During this period: Avoid full-throttle starts and rapid

acceleration.
Avoid hard braking. New brakes
need to be broken-in by moderate
use for the first 200 miles (300

km).

You should follow these same re- commendations with an overhauledor exchanged engine, or when the
brakes are relined.
Gasoline

Your Honda is designed to operate on unleaded gasoline.
We recommend gasolines containing detergent additives that help prevent
fuel system and engine deposits.
Using gasoline containing lead will
damage your car's emissions
controls. This contributes to air
pollution.
In Canada, some gasolines contain
an octane-enhancing additive called
MMT. If you use such gasolines,
your emission control system performance may deteriorate and
the Malfunction Indicator Lamp on
your instrument panel may turn on. If this happens, contact your
authorized Honda dealer for service.
(U.S. DX, HX, EX models, and Canadian

DX and Si models)

Use an unleaded gasoline with a
pump octane number of 86 or higher. Use of a lower octane gasoline can
cause a persistent, heavy metallic
rapping noise in the engine that can
lead to mechanical damage.

(U.S. Si model and Canadian SiR model)

Use a premium unleaded gasoline
with a pump octane number of 91 or higher.
If you are unable to find premium
unleaded gasoline, you may substi-
tute an unleaded regular gasoline.
The engine will compensate for the lower octane, but you may notice aslight decrease in power as a result.

Service Station Procedures

Filling the Fuel Tank
1. Because the fuel fill cap is on the driver's side of the car, park with
that side closest to the service

station pumps.

2. Open the fuel fill door by pulling on the handle to the left of thedriver's seat.
3. Remove the fuel fill cap slowly. You may hear a hissing sound aspressure inside the tank escapes. 4. Stop filling the tank after the fuel
pump automatically clicks off. Donot try to "top off" the tank, leave
some room for the fuel to expand
with temperature changes.
Your car has an on-board refueling
vapor recovery system to help keep fuel vapors from going into
the atmosphere. If the fuel pumpkeeps clicking off even though the
tank is not full, there may be a
problem with this system. Consult
your dealer.
5. Screw the fuel fill cap back on, tighten it until it clicks at least
three times. If you do not properlytighten the cap, the Malfunction
Indicator Lamp may come on (see
page 233).
6. Push the fuel fill door closed until it latches.

Before Driving

FUEL FILL CAP
Gasoline is highly flammable
and explosive. You can be burned or seriously injured
when handling fuel.

Stop the engine and keep
heat, sparks, and flame away.
Handle fuel only outdoors. Wipe up spills immediately.
