Jetta V6-2.8L (BDF) (2002)
To ensure battery seats securely, only install batteries with a 10.5 mm battery foot strip and adhere to the following work sequences:
-
Install battery so battery carrier lug -arrow- engages in battery foot strip cut-out -1-.
It must not be possible to move a battery to the left or to the right.
Battery is inserted correctly when center cut-out in battery foot strip aligns with threaded hole in battery carrier -arrows-
-
On batteries with a hose for central venting ensure that the hose is not squashed. Only then can the battery vent freely.
-
On batteries without a hose for central venting ensure that the opening on the upper side of the battery cover is not blocked.
NOTE: New generation batteries are equipped with a central gas venting system and integrated flame trap. 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.
