Rolling backwards rattle

Hello all. 2023 Tacoma Off Road. I was at stop light on a slight incline, truck was in Drive, I let off the brake the truck rolled back about 2 feet, the truck rattled with noise and warning light came up on the dash. The warning light was orange with the two wavey lines. Is something I should be concerned with?

 

Nope, normal for the truck. The noise and lights are the ABS system firing to slow the roll. It’s a weird and unsettling characteristic of the offroad’s braking system that takes some get used to.
