The automatic driving lock needs to be set by the computer, but it can't be set by yourself. You should go to the 4S store and ask the after-sales service to set it for you. After the setting is completed, it will automatically lock when you drive more than 15 yards. The car will automatically unlock when you park and turn off or pull out the key. In fact, this has its pros and cons. If you are thinking about children, you should use the child seat and the child safety lock in the back row.
