Catalytic Converter

A catalytic converter is installed in the exhaust system to help
clean-up the 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 40.
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
— Don't turn the key off while the engine is running above idl e
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.
