    6. Plug the coupler into the charge port inlet until fully engaged, indicated by an audible click.

      When the coupler engages, the stop charging button illuminates, and the inlet status lamp and the inlet lock lamp go out.

      As a connection is being established between the charger and the vehicle, the charging status lamp and the battery charging lamp pulse orange.

      When the connection is made and charging of the high-voltage batteries begins, the charging status lamp and the battery charging lamp pulse green.

      Note: If the coupler is not fully engaged, charging is limited at 1Kw. If this occurs, press the charge stop button, then remove the charge coupler. When the charging station resets, indicating it is available, restart the charging procedure.
      1. When the vehicle is finished charging, the high-voltage batteries have either charged to 100 percent or reached the target state of charge, the charging status lamp and battery charging lamp illuminate a steady green.

        If charging with the keyswitch OFF, both the charging status and battery charging lamps on the charging port turn off; if charging with the keyswitch ON, both lamps stay on.

        The blue charger connected telltale, as shown in Fig., remains illuminated until the coupler is unplugged from the vehicle inlet.

        Important: Never release the park brake while the charging coupler is plugged in, or the truck may roll and cause damage to the equipment.
        1. When charging is complete, press the coupler's top latch button and remove the charging coupler from the vehicle inlet before releasing the park brake. If the park brake is released prematurely, a warning window appears on the driver display and a continuous chime sounds until the issue is resolved. The dash label, shown in Fig., is a reminder to unplug the charging cable before releasing the park brake.
