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:
- Use only unleaded fuel. Even a small amount of leaded fuel 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.

- Avoid fire hazards. Do not drive

- 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 engine is running.

The exhaust gas is very hot.
