Power Steering UPPER LEVEL Always use Honda Power Steering Fluid. If it is not available, you may use another power steering fluid as an emergency replacement. However, continued use can cause increased wear and poor steering in cold weather. Have the power steering system flushed and refilled with Honda PSF as soon as possible. A low power steering fluid level can indicate a leak in the system. Check the fluid level frequently and have the system inspected as soon as possible. NOTICE Turning the steering wheel to full left or right lock and holding it there can damage the power steering pump. LOWER LEVEL Check the level when the engine is cold. Look at the side of the reservoir. The fluid should be between the UPPER LEVEL and LOWER LEVEL. If it is below the LOWER LEVEL, add power steering fluid to the UPPER LEVEL. Maintenance
