The hydraulic clutch linkage in your vehicle is self-adjusting. The master cylinder reservoir is filled with DOT-3 brake fluid.
It is not necessary to regularly check the fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak.
The hydraulic clutch and brake master cylinder use the same reservoir.
A fluid loss in this system could indicate a problem. Have the system inspected and repaired.
The reservoir is located at the back of the engine compartment, on the driver side of the vehicle. Engine Compartment Overview.
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 Scheduled Maintenance and Recommended Fluids and Lubricants.
Check that the fluid level is at or above the MIN mark. If the level is below the MIN mark, see the instructions on the reservoir cap.
