The seat is lowered because the gear lever in the neutral position is higher than the plastic safety protection of the seat. When the driver comes out of the car, the driver pushes it every time, and the seat falls slightly. To solve the problem, you can change the shape of the bolts using the rack-mounting knife (give them the shape of the bolts (the clockwise right-up, right down) and the protrusions on the inner side of the handle (to cut by 30% on the right side if you look at them). This changes the position of the seat adjustment lever.
You can also remove the lever and warm the handle a little, and then slightly isolate it so that the top point is approximately 2 cm.
