Hello and welcome to Just, Super mechanic here. About your vehicle.

There really isn't any reset procedures for the coolant level sensor. When the coolant tank is filled, the low coolant light should go out. I know that they sometimes don't and what I do is just tap on the tank lightly with a rubber hammer. That will normally allow the float to come back up and turn the low coolant light out. Seems you have to do that whenever the tank gets very low or empty.
