NOTE:

Function: Gases produced during charging escape through a central opening on the side of the upper cover. The integrated flame trap prevents flammable gases in the battery from igniting. The flame trap is comprised of a small round fiberglass mat with a diameter of 15 mm and a thickness of 2 mm. Working as a one-way-valve, it allows gases produced during charging to vent.
- To ensure proper seating of installed battery, use only genuine Volkswagen approved replacement batteries, and adhere to the following procedures.
