To start with, switch off your car and make sure the engine has cooled down before you proceed.
Now, open the hood and take a good look at the entire system.
Find the clutch reservoir. Since you have a hydraulic clutch in your car, chances are that the reservoir is located behind or near the brake master cylinder. Remember, the clutch reservoir will be smaller in size to the brake cylinder so you will have to do a little digging to get your hands on it. If you cannot find the reservoir, get your owner’s manual and check where the reservoir is located.
Since you have located the reservoir now, it is time to check the fluid in the reservoir. In most cases, there will be a marker on the reservoir, indicating that the fluid should always be above it. In older models, the reservoir never used to be transparent. The marker will be present on the lid. In newer models, the reservoir itself has the marker since it is transparent. If there is no marker, just make sure the fluid is more than half-full in the reservoir.
You will have to refill the reservoir if the fluid is below the marker or less than half of it. In doing so, you will have to make sure there are no leakages. You can find this out by cleaning the reservoir first and check if the fluid is staying in the reservoir or not.
