In case of emergency Confirm that the cooling fan is turning. If the fan is not turning, immediately turn the engine off and contact your authorized 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 "LOW" mark, add coolant up to the "FULL" 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. If you remove the radiator cap from a hot radiator, first wrap a thick cloth around the radiator cap, then turn the cap counterclockwise slowly without pressing down until it stops. Release the pressure from the radiator. After the pressure has been fully released, remove the cap by pressing down and turning it. Towing If towing is necessary, it is best done by your SUBARU dealer or a commercial towing service. Observe the following procedures for safety. WARNING Never tow AWD vehicles (both AT and MT) with the front wheels raised off the ground while the rear wheels are on the ground, or with the rear wheels raised off the ground while the front wheels are on the ground.
