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.
The hydraulic clutch fluid reservoir is located behind the front panel on the driver's side of the vehicle.
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 C: Recommended Fluids and Lubricants for more information.
The proper fluid should be added if the fluid level is not between the MAX (Maximum) and MIN (Minimum) marks.
