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 (mis-
firing, 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.
Periodic inspections
To keep your vehicle in the best condition at all times, always have the
recommended maintenance services listed in the maintenance schedulein the “Warranty and Maintenance Booklet ” performed at the specified
time or mileage intervals.
Driving in foreign countries
When planning to use your vehicle in another country: Confirm the availability of the correct fuel. (Refer to the “Fuel require-
ment” section in chapter 7.)
Comply with all regulations and requirements of each country.
