Check Engine Warning Light
This light comes on for a couple of seconds each time the ignition is
turned on. It will also come on, and remain on, if there is a malfunction in the emission control system. If the light comes on
while driving, avoid driving at high speed, and have the system
checked by a Honda dealer as soon as possible.

With the parking brake set, the warning light should go on when the ignition switch is turned to II or III. With the parking brake released,
the light should go on when the ignition switch is turned to III. If the light goes on at any other time, it means the brake fluid level in themaster cylinder reservoir is too low; add fluid and have your dealer
check for leaks and brake pad wear immediately. (See page 84 )

Catalytic Converter

A catalytic converter is installed in the exhaust system to help
clean-up the harmful exhaust gases that can cause air pollution.
To be effective, the converter must work at high temperature, so don't park your car over dry grass, leaves or anything else that

could burn easily.

To stay effective, the converter must not be contaminated by

leaded gasoline; use only unleaded gas as explained on page 54.

CAUTION:
The converter can be overheated and damaged if it's fed too much
unburned fuel mixture from the engine, so:
— Don't push or tow the car to start it; if the battery is dead, jump start the car as shown on page 110.
— Don't turn the key off while the engine is running above idle
speed.

— Don't change the ignition timing, or remove any emission control
parts.

— Use only the spark plugs specified in this manual. — Don't keep driving your car if it isn't running properly, or if its CHARGE warning light comes on; have it checked by your
Honda dealer.
