Installing
Notes: - Remove bolt -3- and remove hold-down clamp -2-.
Tightening torque: 15 Nm (11 ft lb)
- Lift battery -1- out of battery tray.
The newest generation of batteries is equipped with a central gas vent
and flame trap by means of a "baffle." Function: the gas produced during charging escapes at one place
through an opening in the top of the cover. The flame trap (which
prevents the flammable gas located in the battery from igniting) is also
integrated in this unit. For proper venting of the battery via the diffuser and the hose, it is
important that the hose attached to the central gas vent does not
become pinched off during installation. The diffuser consists of a small round glass fiber mat having a
diameter of approximately 15 mm and a thickness of 2 mm. It
functions similar to a valve, i.e., it allows the gas formed in the battery
to flow out.

Note:

When installing the battery (if the battery has a central gas vent), make
absolutely certain that the hose is not pinched off. This allows the battery
be freely vented via the diffuser and the hose. If the battery does not have
a hose, make sure that the opening on the top of the battery's cover is not
plugged.
Make sure battery is securely mounted
If the battery is not secured properly, there is a risk that the following
might occur: - Install in reverse order of removal.
Shortened service life due to damage caused by vibrationBattery cell and plate damageDamage to battery case by the hold-down clamp (possible release of
electrolyte resulting in costly damage). Poor collision safety
