  2. Caution: Refer to Brake Fluid Irritant Caution in the Preface section.

    Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.

    Notice: DO NOT use fluid which has been bled from a hydraulic clutch system, in order to fill the clutch master cylinder reservoir, due to the possibility that the fluid may be aerated, have too much moisture content, or be contaminated and may cause system or vehicle damage.

  3. Remove the clutch fluid reservoir cap (1) and ensure the clutch fluid reservoir (2) is filled to the fill line with new hydraulic fluid. Add fluid if required from a clean sealed container. For clutch fluid specifications, refer to General Specifications.
  4. Stroke the clutch pedal from the up stop to the down stop position at least 15 times slowly to avoid aeration of fluid.
  5. Caution: Refer to Safety Glasses Caution in the Preface section.
