Does anyone know why this red light on bottom right and warning go on. I can’t start my (very expensive). truck and even back it in garage! Very frustrating!

Second symbol - Illuminates when your vehicle is first switched on to show it is properly functioning.
If it illuminates when the motor is running, this indicates your vehicle requires service. Have your vehicle checked as soon as possible.
Driving when this warning lamp is on drains the 12V battery. If you must drive with this light on, turn off all accessories.

The owners manual can explain a lot and save you time and money, maybe even your life.

You can go to your dealer, an auto parts shop, or a friend with an OBDII reader and software to read any fault codes. The best case to hope for is that your 12V is low and causing glitches.

I would definitely get a reader so if it happened again, you can monitor the conditions and errors before you reset. Knowing what your 12V SOC is at is always nice. I am not sure how accurate is the Ford website with that info. What is puzzling is that they can show it on the website but not in the truck.

Your truck isn't turned on fully so you get the battery icon.

Did you recently charge on 120v?
