How to turn on Blind Spot

[Tom Brennan]

Hi, I have a 2019 Expedition Platinum Edition. Somehow my Blind Spot off indicator has appeared on my display. I have no idea how it got turned off. I have searched online and various videos show it can be turned off via the information display cluster or on the entertainment panel. I cannot find blind spot toggles on either interface with the exception of an option under towing on the cluster. The towing toggle seems to only work when the system is sensing a trailer. Does anyone know how to turn on the Blind Spot feature?
Thanks
T
