Should the heel be off the ground when releasing the clutch?

[DiJaxon]

When releasing the clutch, the heel should be off the ground. The functions of the clutch are: 1. Gradually increase the driving force of the car to ensure a smooth start; 2. Temporarily separate the engine and transmission for gear shifting; 3. Prevent overload of the transmission system; 4. Reduce torsional vibration impact from the engine and prolong the service life of transmission gears. Maintenance and servicing items for the clutch include: 1. Checking the fluid level in the clutch reservoir; 2. Inspecting the clutch hydraulic control mechanism for leaks; 3. Depressing the clutch pedal to check its responsiveness; 4. Checking the height of the clutch pedal; 5. Inspecting the clutch release point; 6. Verifying the working condition of the clutch; 7. Bleeding air from the clutch hydraulic system.
