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.
The vehicle network starts to wake-up at the moment any side door is opened in order to increase the start-up speed of electrical components and the network awake cumulative time count begins by the customer doing any one of the following wake-up triggers: Open any door(s), Unlock doors, Open liftgate, Depress brake pedal, Push start/stop button, Other operations that wake-up the network.
No dealer visit is required. The warning message can be cleared by starting the engine and idling or driving for 5 minutes or longer.
