DRIVING TIPS
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 exhaust system.
. Do not drive with an extremely low fuel level.
