Crook, the left button in the gear won't come out.

The reason is poor contact of the brake switch.

The design of the car is to put it into gear only by stepping on the brake, which is relatively safe It is also possible that there is something wrong with the throttle, the throttle opening does not match the engine computer data, and the computer is not in gear, so the throttle matching data can be cleared. In order to ensure safety and prevent accidents caused by unexpected forward or backward gears. The unlock button is a completely mechanical device. When the thumb is pressed, the shift lever can only be moved when it is out of the groove or step.
