The power steering fluid expands greatly as its temperature rises; the fluid level differs according to fluid temperature. Therefore, the reservoir tank has two different checking ranges for hot and cold fluids. Check the power steering fluid level monthly. 1. Park the vehicle on a level surface, and stop the engine. 2. Check the fluid level of the reservoir tank. When the fluid is hot after the vehicle has been run: Check that the oil level is between "HOT MIN" and "HOT MAX" on the surface of the reservoir tank. When the fluid is cool before the vehicle is run: Check that the oil level is between "COLD MIN" and "COLD MAX" on the surface of the reservoir tank. 3. If the fluid level is lower than the applicable "MIN" line, add the recommended fluid as necessary to bring the level between the "MIN" and "MAX" line. If the fluid level is extreme low, it may indicate possible leakage. Consult your SUBARU dealer for an inspection. - CONTINUED - HOT MAX COLD MAX HOT MIN COLD MIN UBB519BB Be careful not to burn yourself because the fluid may be hot.
