The other day upon starting my car in the morning noticed that the car charger was left on overnight and didnt think nothing of it,after coming back home and shutting off the car noticed this on my screen and the dealer checked the battery level and it was just fine,think the car protects itself,also found this on the owners manuel related to this. Z Turn Power Off to
Save Battery
Displayed when the battery management
system determines that:
• the battery is at a low state of charge or,
• the ignition has been in accessory position
or on position with the engine off for
approximately 45 minutes.
Turn the ignition off as soon as possible to
protect the battery. This message will clear
once the vehicle has been started and the
battery state of charge has recovered. Turning
off unnecessary electrical loads will allow
faster battery state-of-charge recovery
