WARNING
● 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 temperatures.
● Keep everyone and flammable materials away from the exhaust pipe while the

The catalytic converter is installed in the exhaust system. It serves as catalyst
to reduce HC, CO and NOx in exhaust gases, thus providing cleaner exhaust.
To avoid damage to the catalytic converter:
● Use only unleaded gasoline. Even a small amount of leaded gasoline will damage
the catalytic converter.
● Never start the engine by pushing or pulling the vehicle.
● Avoid racing the engine.
● Never turn off the ignition switch while the vehicle is moving.
● 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.
● Do not apply undercoating or rust prevention treatment to the heat shield of catalytic
converter and the exhaust system.
● Do not drive with an extremely low fuel level.
