Battery Protection Mode; Audio Functions - Aston Martin DB 9 2007 Manual

Battery Protection Mode

Using the vehicle electrical systems, i.e. the infotainment
system, with the ignition key at position 'I' (engine off) will
drain the battery charge. Eventually the battery will drain to
such a low level that it will not start the engine.
Replace the battery as soon as possible, if the battery is
not capable of starting the engine.
To avoid this happening, a series of safety mechanisms shut
down nonessential electrical systems before excessive battery
drain takes place.
Warning messages will appear indicating the state of the
battery charge.
(Refer to 'Battery Protection Mode', page 11.37).
