The clutch reservoir is on the bulkhead / firewall by the brake fluid reservoir under the bonnet / hood. Its likely to be low or out of fluid. If this is the case its more than likely that you have a leak from the master cylinder or slave cylinder. First have a look from the clutch pedal side for any signs of fluid around the firewall area. Then follow the pipe from the master cylinder down to the gearbox bellhousing. The slave cylinder is what it attaches to. Chances are there will be a leak from under the rubber boot where the rod exits. In some cases you will have to remove it from the bell housing to check for leak. You can usually leave the pipework on at this stage. Carefully prize of the dust cover and check for leaks. Be careful not to let it drip in your eyes. If its leaking remove completely and replace it or the seals. Refit and bleed the clutch after topping up reservoir.
