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.
The hydraulic clutch reservoir is located in the engine compartment on the driver's side, near the brake master cylinder reservoir. See Engine Compartment Overview for more information on location.
Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid. See Part B: Owner Checks and Services and Part D: Recommended Fluids and Lubricants .
Make sure the fluid level is at the MIN line shown.
If it isn't, remove the cap and add the proper fluid until the level reaches the MIN line on the side of the reservoir.
