Hydraulic Clutch
It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.
When to Check and What to Use

The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview for reservoir location.
Refer to the Maintenance Schedule for the proper fluid to use. See Recommended Fluids and Lubricants.
The fluid requires changing every two years. See Maintenance Schedule.
How to Check and Add Fluid
Visually check the clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The hydraulic clutch fluid system should be closed and sealed.
Do not remove the cap to check the fluid level or to top–off the fluid level.
Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line.
