When a vehicle is "off" many electrically powered devices will continue to draw power from the battery, which will eventually deplete the battery. Instead of leaving such devices on, when the engine is shut off, a message is transmitted from a vehicle's telematics communications device to one or more of: the operator, a telematics service provider or elsewhere, and which notifies the recipient of the power-down condition. The recipient of the message can thereafter respond with a directive that tells the telematics communications device which devices to leave powered on, turn off or schedule to be shut off. Absent such a message, the system powers down devices according to a default power down ordering. |
