STARTING AND DRIVING THREE-WAY CATALYTIC CONVERTER The three-way catalytic converter located at the confluence of exhaust pipes looks somewhat like a muffler, but its purpose is to reduce pollutants in the exhaust gas. ! CAUTION S Keep people and combustible materials away from the exhaust pipe while the engine is running. The exhaust gas if very hot. S Do not drive, idle or park your vehicle over anything that might burn easily such as grass, leaves, paper or rags. Three-way catalytic converters are emission control devices installed in the exhaust system. 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: S Use only unleaded gasoline. S 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. S Do not allow the engine to run at idle speed for more than 20 minutes. S Avoid racing the engine. S Do not push-start or pull-start your vehicle. 126

STARTING AND DRIVING

THREE–WAY CATALYTIC
CONVERTER
Three–way catalytic converters are emission control
devices installed in the exhaust system.
The three–way catalytic converter located at the confluence
of exhaust pipes looks somewhat like a muffler, but its
purpose is to reduce pollutants in the exhaust gas.
CAUTION
!
S
Keep people and combustible materials away from
the exhaust pipe while the engine is running.
The
exhaust gas if very hot.
S
Do not drive, idle or park your vehicle over any-
thing 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:
S
Use only unleaded gasoline.
S
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.
S
Do not allow the engine to run at idle speed for
more than 20 minutes.
S
Avoid racing the engine.
S
Do not push–start or pull–start your vehicle.
