Heating and Cooling

The vents, heater and air conditioner are combined in one system;
adjusting four basic controls to different settings can provide a full range of interior temperatures for safe and comfortable driving.
Air conditioner: optional

Ventilation

The flow-through ventilation system can provide fresh air to the
interior when the car is moving or stopped, even with the windows

closed.

NOTE:

For proper air flow, the flow-through vents must not be covered.Keep the air inlet at the base of the windshield free of leaves or
other debris.
You can adjust the controls to direct cool or warm outside air
throughout the car for defogging windows, heating, or cooling by turning on the fan.

Dash Vents
The corner vents can be used for flow-through ventilation, or for heating and air conditioning. When the car is moving, the driver's
corner vent can also route fresh air directly from the outside bysliding the corner vent lever below it to the right and shutting it off
from the heater and air conditioner system.
The louvers in the corner and center vents can be tilted up or down and right or left, to change the direction of air flow.

Recirculation Lever
Sliding the lever from the position to the position
shuts off outside air and recirculates the air inside the car. If the
heater or air conditioner is on, and you want to warm up or cool
down the interior more quickly, or keep smoke or dust out of the car without losing the heat or cool function, simply slide the lever to the position.

NOTE:
The windows may become fogged if the system is in the po-
sition for an extended period of time with the air conditioner off. As soon as the interior is warmed, slide the lever to the posi-

tion.

How to Use the Controls

To Ventilate

Turn the temperature control dial counterclockwise, slide the recirculation lever to the position and the function lever to
the position. Switch the fan on and outside air will flow
through the corner and center vents. To change air distribution,
slide the function lever to the position, and outside air will
also flow from the floor level outlet at the heater.

To Heat
Switch the fan on, turn the temperature control dial clockwise, slide the function lever to the position and the recirculation lever
to the position, and warmed (outside) air will begin flowing

from the floor outlets.

To warm up the interior quickly, slide the recirculation lever to the
position so inside air will recirculate to the heater.

The windows may become fogged if the system is in the po-

sition for an extended period of time. As soon as the interior is
warmed, slide the lever to the position.

To Dehumidify (with optional air conditioner)
Because an air conditioner dehumidifies as it works, you can use it
in cool or cold weather to help defog the windows. Just switch the
fan on, push the A/C button, select the desired function and adjust
the temperature control dial to a comfortable setting.
NOTE:
This setting is desirable for most operating conditions in ambient temperatures above approximately 32°F (0°C).ProCarManuals.comMain Menu s t

Engine Exhaust Gas Warning
A properly maintained car is your best protection against exhaust
gas entering the passenger compartment.
The exhaust system should be thoroughly inspected by a compe-

tent mechanic whenever:
The car is raised for oil change.You notice a change in the sound of the exhaust. The exhaust system or the rear or underside of the car is

damaged.
Avoid breathing exhaust gases. They contain carbon monoxide,
which is a colorless, odorless gas that can cause loss of con-
sciousness and eventual death. If you suspect that exhaust gas is entering the passenger compartment, have the cause deter-mined and corrected as soon as possible. If you must driveunder these conditions, drive only with all windows fully open. Do not drive with the hatch/trunk lid open. An open hatch/trunk
may draw exhaust gases into the passenger compartment. If
you must drive with the hatch/trunk open, drive only with all the
windows wide open. Do not run the engine in confined areas, such as garages, any
longer than necessary to move the car in or out.
If you must sit in a parked car with the engine running for more
than a short time, adjust the heating/ventilation system as
follows:
1.Set the function lever to the position.
2.Set the temperature control dial for best comfort. 3.Set the recirculation lever to the position.
4.Turn the fan to the highest speed.

NOTE:

To insure proper operation of the car's ventilation system, keep the

front air inlet clear of snow, mud, leaves or other obstructions.ProCarManuals.comMain Menu s t

Brakes

Brake System Design

The diagonally-separated dual serv-
ice brake system is designed so half
the system will still provide braking action if the other half fails.
Stopping the car after losing the brake fluid from half the system will
require more pedal pressure and pedal travel than normal. Also, the
distance required to stop will be longer using only half the brake
system. If the brakes fail suddenly, downshift to a lower gear for increased engine braking, and pull off the road as soon as possible.
It is dangerous to drive your car with a problem in either thebrake electrical or hydraulic system; have your dealer check
both systems if you suspect brake trouble.
Driving through deep water may affect the brakes.Check their effectiveness by pressing the brake pedal gently.
If the car does not slow down at the normal rate, continue
gently applying the brakes, while maintaining a safe speed, until
they dry out and normal performance returns. Do not ride the brakes. In other words, don't put your foot on
the brake pedal unless you intend to brake. This causes excessive brake wear and can damage, or lead to loss of braking
effectiveness through overheating. Your brake lights may also
confuse drivers behind you.
Brake Wear Both front and rear brakes should be inspected for wear at the
intervals shown in the Maintenance Schedule on page 70.
When the brakes require maintenance, use only genuine Honda
replacement parts or their equivalent.
