In case of emergency J If no steam is coming from the engine compartment 1. Keep the engine running at idling speed. 2. Open the hood to ventilate the engine compartment. Confirm that the cooling fan is turning. If the fan is not turning, immediately turn the engine off and contact your authorized SUBARU dealer for repair. 3. After the engine coolant temperature has dropped, turn off the engine. If the temperature gauge stays at the overheated zone, turn the engine off. 4. After the engine has fully cooled down, check the coolant level in the reserve tank. If the coolant level is below the "MIN" mark, add coolant up to the "MAX" mark. 5. If there is no coolant in the reserve tank, add coolant to the reserve tank. Then remove the radiator cap and fill the radiator with coolant.
