How does the ratchet belt distinguish between automatic and manual

1. The shift lever of automatic transmission is marked with the letters P, D, R, N, etc., respectively representing parking, driving, reversing, neutral, etc.
2. Manual shift is 1, 2, 3, 4, 5, R and other letters, respectively represent 1234 reverse gear and so on.
3. Another point is that manual transmission vehicles need a clutch to operate, so there must be a clutch pedal, on the left of the brake, operated with the left foot.
