To protect the charging port lid lock motor and charging connector lock motor, if the charging port lid lock or charging connector lock is operated repeatedly, operation of the lock will be prohibited. Wait for 3 minutes or more to allow the motor to cool and then resume the inspection.
To protect the charging port lid lock motor and charging connector lock motor, if the charging port lid lock and charging connector lock are operated repeatedly in quick succession, operation of the lock will be prohibited for a certain amount of time. Wait for 3 seconds or more after operation was prohibited and then resume the inspection.
If the charging connector lock is dirty or frozen, or if foreign matter is caught between the charging connector and charging connector lock, the charging connector may not be able to be locked/unlocked. Clean the charging connector lock before performing the inspection.
If a charging cable other than the charging cable provided with the vehicle is used, the charging connector lock may not operate correctly. Check that the lock and unlock functions of the charging connector lock operate properly using the charging cable provided with the vehicle before proceeding with the inspection.
When the charging connector is connected, changing the "Charging Connector Lock" customize setting (to "Auto Lock" or "Auto Lock & Auto Unlock") will not lock or unlock the charging connector.
