Warning and Indicator Lights (cont'd)

Oil Pressure Warning Light

A severe fluctuation in engine oil pressure will cause this light to
flash on and off. You should stop as soon as possible, check the oil level, and add oil if necessary.
The oil pressure warning light will come on, and remain on, if there is insufficient oil pressure or when the ignition switch is turned on
with the engine not running. If the light should stay on while driving,
get the car off the road as soon as you can, turn the engine off and
check the engine oil level (see page 83).
Even if the oil level is correct, the engine should be checked by a
Honda dealer before the car is driven again.

NOTE:

The oil pressure warning light will only light as a result of low oil pressure. It is not directly an oil level indicator.
CAUTION:
Running the engine while the oil pressure warning light is on
constantly may cause immediate and severe engine damage.
Cruise Control Indicator Light
When the cruise control system is on, this indicator light is on (see
page 35 and 36).

Fuel Reserve Warning Light

If the warning light glows, it means you should refuel, because the
tank contains less than:

Cruise Control
Cruise Control
The Cruise Control system allows you to set and automatically maintain any speed above 30 mph (45 km/h) without keeping your
foot on the accelerator. As its name implies, it is meant for cruising

on straight, uncongested highways or freeways. It is not

recommended to be used in traffic, on winding roads or in bad weather conditions where the driver should have total control.
To Set the Cruise Control:
Push the CRUISE CONTROL

master switch on the dash; the
indicator light will come on. Accelerate to the desired
speed, then, push and release

the SET switch on the
steering wheel. The Cruise
Control light on the

instrument panel will come

on.

The speed you were going when you released the SET switch is the speed the Cruise Control will hold. You can then "fine tune" the set
speed by briefly holding and releasing the SET switch to decrease it
a few mph or pushing the RESUME switch to slightly increase it.
To Cancel the Cruise Control:
Push the CRUISE CONTROL

master switch and the indicator
light will go off (this also erases the memory of the set speed), if you must temporarily disengage the system (but you wish to
retain the memory of the set speed): tap the brake pedal, or the clutch pedal (manual transmission) or move the automatic trans-mission shift lever to N (Neutral). If you are still going above 30 mph(45 km/h), you can return to the set speed by simply pushing the
RESUME switch. If the car has decelerated below approximately 30 mph (45 km/h),you can return to the set speed by using the ac-
celerator conventionally until your speed is above 30 mph (45 km/h) and then pushing the RESUME switch.

Cruise Control (cont'd)

To Change the Set Speed: To a faster speed — For gradual acceleration with your foot off the
accelerator, push
and hold the RESUME switch until you reach the
desired speed; release the switch and the system's memory will be re-programmed to the new speed.
For faster acceleration, push the accelerator until you reach the
desired speed, then push and release the SET switch to re-program
the system.

To a slower speed — push and hold the SET switch and the car willcoast; when you reach the desired slower speed, release the switchand the system will be re-programmed.
For temporary acceleration above the set speed, such as for passing,
use the accelerator pedal conventionally. When you want to return
to the set speed, take your foot off the accelerator and coast without applying the brakes.
The Cruise Control automates the function of the accelerator pedal to maintain your car at a constant speed. This can be a
convenience on long trips, but it can also be a danger if there are many other cars on the road or if the road is unfamiliar. Pay strict
attention to the responsibility of driving whenever using the Cruise Control.

CAUTION:

Because the Cruise Control directly activates the accelerator pedal, don't rest your foot under the pedal when the Cruise
Control is on; it may pull the pedal down onto your foot.
NOTE:
With Cruise Control on, your speed will still vary slightly,particularly when going up or down hills.
Do not drive with your foot on the brake or clutch pedal (manual
transmission), as this will cause the Cruise Control to disengage.ProCarManuals.comMain Menu t s

Evaporative Emission Control System
The Evaporative Emission Control System is designed to prevent
fuel vapors from escaping into the atmosphere.

(2.0 Si,Si)

Fuel vapors from the fuel tank are directed into the charcoal
canister where they are adsorbed and stored while the engine is
stopped or idling. When the coolant temperature rises to a certain
value, the vapors are drawn into the engine through the throttle body and the intake manifold during normal engine operation.
(2.0 S)Fuel vapors from the fuel tank and carburetor are directed into the
charcoal canister where they are adsorbed and stored while the
engine is stopped.
When the engine is running and engine coolant temperature is above
the set temperature of the thermo sensor, the purge control diaphragm valve is open so that fuel vapors in the charcoal canister may be drawn into the engine through the carburetor and the intake
manifold.
Engine Exhaust Controls
The engine exhaust emission control systems are designed to
control combustion during idle, acceleration, cruise, and deceleration.
These systems are entirely separate from the crankcase and evaporative emission control systems described previously. HONDA PGM-FI System (2.0 Si,Si)
The PGM-FI system consists of three independent sub-systems; Air intake, Electronic Control and Fuel Control, thus allowing moreaccurate control of air/fuel ratios under all operating conditions.
The Electronic Control Unit (ECU) detects the amount of air
drawn into the cylinders and determines the amount of fuel to be injected to provide the optimum air/fuel ratio for all engine needs.
