The Operator's Manual gives a very vague explanation. "Inducement General Warning".
The manual shows that "A" is the oil pressure indicator.My guess is LOW Engine Oil Pressure,
if you are concerned about the Red light with lines pointing on a down angle. 🤷♂️
Page 62 of manual is where I was looking
Same issuesLooks like your DEF level is in the red. Try filling the DEF tank and see if that warning goes away. It appears to be a derate symbol.
