The battery is fitted with a ventilation hose which vents hydrogen gas out of the battery compartment through a ventila- tion opening in the bottom of this com- partment. If the battery must be replaced, it is essential that the ventila- tion hose is properly connected to the battery and that it is routed through the ventilation opening provided (see illus- tration).

Be sure the ventilation hose is free of debris.

Only use replacement batteries equip- ped with a ventilation hose. Consult a trained and qualified Volvo service tech- nician.
