If you open the hood, over by the charging port doors are two pull cables. One is to unlock the port door, the other is to retract the charging pin. The manual will tell you which is which by color. Generally, after you use a pull cable the advice is to take it into the dealer to get checked, especially if the cable does not retract properly.
The above works,- couple of pull wires under the bonnet (hood). I had to pull one a few weeks after getting my SUV. No problems since.
They’re coded red and yellow. One for the port door, one for the locking pin. If it’s not obvious which is which, try them both!
