THREE–WAY CATALYTIC
CONVERTERS
31sa03
Three–way catalytic converters are emission control
devices installed in the exhaust system.
The purpose is to reduce pollutants in the exhaust gas.
CAUTION
Keep people and combustible materials away from
the exhaust pipe while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your vehicle over anything
that might burn easily such as grass, leaves, paper or
rags.
NOTICE
A large amount of unburned gases flowing into the
three–way catalytic converter may cause it to overheat
and create a fire hazard. To prevent this and other
damage, observe the following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low fuel level; running
out of fuel could cause the engine to misfire, creating
an excessive load on the three–way catalytic
converter.
Do not allow the engine to run at idle speed for more
than 20 minutes.
Avoid racing the engine.
Do not push–start or pull–start your vehicle.
Do not turn off the ignition while the vehicle is
moving.
Keep your engine in good running order.
Malfunctions in the engine electrical system,
electronic ignition system or fuel system could cause
an extremely high three–way catalytic converter
temperature.
