Hydraulic Clutch There is one reservoir for both the brake and the hydraulic clutch fluid. See Brakes on page 5-36 for more information. The hydraulic clutch linkage in your vehicle is self-adjusting. The master cylinder reservoir is filled with hydraulic fluid. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. How to Check and Add Fluid When to Check and What to Use Refer to the Maintenance Schedule to determine how often you should check the fluid level in your master cylinder reservoir and for the proper fluid. See Part B: Owner Checks and Services on page 6-19 and Part D: Recommended Fluids and Lubricants on page 6-26. To check the fluid level, look on the side of the reservoir. If the fluid reaches the MAX (A) mark on the reservoir, the fluid level is correct. The reservoir is located near the back of the engine compartment on the driver's side of the vehicle. See Engine Compartment Overview on page 5-14 for more information on location. 5-22
