NOTE: Brake fluid and power steering fluid CAN NOT be mixed. Only add brake fluid to the brake master cylinder reservoir. Only add power steering fluid to the power steering reservoir. 3. Visually verify that the fluid level is above the MIN line adjacent to the reservoir "sight window." If the power steering fluid is below the MIN line, remove the cap and add fluid in small amounts until the level is between the MIN and MAX lines. Reinstall the reservoir cap. 4. 5. It is normal for the fluid level to be above the MAX line after the brake pedal has been pushed several times with the engine off. (If you want to double check it; restart the engine and turn steering wheel to full right turn, the full left turn and then turn engine off and re-check fluid level. It should be between the MIN and MAX line.) 277
