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