Mercedes-Benz is dead. Will the app show the door failure?

I will. When the battery is dead, a symbol similar to the battery will appear on the dashboard, with a plus sign on one side and a minus sign on the other. When the vehicle is running, it will charge the battery. If the symbol of low battery power appears during long-term driving, it means that the battery has been damaged or cannot be recharged, and it is necessary to check and replace the battery in time. The phenomenon of battery power loss is mainly because the car is parked for too long, and the power stored in the car battery is exhausted. Also, I fell asleep in the car with the light on. The battery must be dead at night.
