System Bleeding

When filling the reservoir, make sure that the fluid is clean and not agitated prior to use. Pour the fluid slowly to minimize aeration.

  1. Check that the reservoir level is well above the Min. mark. Add fluid if required and install the reservoir cap loosely to avoid fluid splashes during system bleeding.
  2. Start the engine and run for several minutes. Check the returning fluid in reservoir. When the air bubbles cease to flow, top up the reservoir. Move to step 3.
  3. Turn the steering hard over on one lock. Run the engine for several minutes. Check the returning fluid in reservoir. When the air bubbles cease to flow, top up the reservoir. Move to step 4.
  4. Turn the steering hard over on opposite lock. Run the engine for several minutes. Check the returning fluid in the reservoir. When the air bubbles cease to flow, top up reservoir. Move to step 5.
  5. Allow the engine to idle for 5 minutes with the road wheels in the straight ahead position.
  6. Briefly turn the steering to one lock and then to the opposite lock. If no air sounds are heard, bleeding was successful.
    If air noises are present, repeat the bleeding procedure.
  7. Top-up the reservoir to the max. level and secure the reservoir cap.
