Dash warning lights

[Steve ES350]

Last week I replaced the battery in my new (to me) 2013 RX350, used a jumper to not screw up all the settings. Then three days ago  I used an OBD2 (carista) to check for ECU faults, and all was good. Disconnected it, and left the car parked. Today, upon driving it, the dash is lit up like a Christmas tree. I'm hoping this is a quick series of off/on switches or similar... help please

Did you check OBD2 for codes since the warning lights event?

I would also check that the battery cables are tight and check the battery voltage before and after starting the vehicle.
