Catalytic converter

WARNING
D Avoid fire hazards. Do not drive or park the vehicle anywhere
near flammable materials (e.g. grass, paper, rags or leaves), be-
cause the catalytic converter operates at very high temperatures.
D Keep everyone and flammable materials away from the ex-
haust pipe while the engine is running. The exhaust gas is very
hot.
Catalytic converter
The catalytic converter is installed in the exhaust system. It serves as a
catalyst to reduce HC, CO and NOx in exhaust gases, thus providing
cleaner exhaust.
To avoid damage to the catalytic converter:
D Use only unleaded fuel. Even a small amount of leaded fuel will dam-
age the catalytic converter.
D Never start the engine by pushing or pulling the vehicle.
D Avoid racing the engine.
D Never turn off the ignition switch while the vehicle is moving.
D Keep your engine tuned-up. If you feel the engine running rough (mis-
firing, backfiring or incomplete combustion), have your vehicle checked
and repaired by an authorized SUBARU dealer.
D Do not apply undercoating or rust prevention treatment to the heat
shield of catalytic converter and the exhaust system
