Hydraulic Clutch

The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir is
filled with hydraulic clutch fluid.
It is not necessary to regularly check clutch fluid unless
you suspect there is a leak in the system. Adding
fluid won't correct a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
