Subaru Forester: Driving tips / 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:

• 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 the ignition switch to the “OFF” position 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.

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 engine is running. The exhaust gas is very hot.
