For vehicles with a manual transmission, it is not necessary to regularly check brake/clutch fluid unless there is a leak suspected.
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 brake/hydraulic clutch fluid reservoir cap has either a symbol or text specifying the type of brake fluid. The common brake/clutch fluid reservoir is filled with GM approved DOT 3 brake fluid as indicated on the reservoir cap.
How to Check and Add Fluid
Visually check the brake/clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The brake/ 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.
