Hydraulic Clutch There is one reservoir for both the brake and the hydraulic clutch fluid. See Brakes on page 299 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 389 and Part D: Recommended Fluids and Lubricants on page 396. 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. If the fluid does not reach the MIN (B) mark on the reservoir, then fluid needs to be added. 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 276 for more information on location. 286
