WARNING
Ventilation hose:
• The battery generates hydrogen gas,
which is flammable and explosive. 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.
NOTE
After the battery has been disconnected or
replaced, lock and unlock the vehicle with
the central locking system's remote control
to reactivate such features as the power
windows, moonroof, courtesy lighting, etc.
