The battery dead if I’m not Drving in couple days

Hello, first check to ensure your battery is fully charged and able to handle a load. Then, it may be necessary to check for a "parasitic draw" -- something that is functioning when it should be off that may be draining down the battery. A total guess is the "hands free link" bluetooth module in this vehicle; I have seen them stay "on" and run the battery down. Do not guess a this though; check and verify when the concern happens next.
