Summary
Some vehicles may have a "Low Battery Risk. Start Vehicle to Charge 12V Battery" warning message in the instrument cluster and a 30 second alarm sound. This is caused by the vehicle's electrical control area network (CAN) entering "Sleep Mode" when the network awake time reaches 30 cumulative minutes without the engine running.
