General Warning Light and Loss of Acceleration

[Julie1306]

Today a red warning light came on in my 2016 Fiat motor home. Then I lost acceleration and just crawled along till I could pull over. I can’t find any mention of this warning light in the manual. Can anyone help please ?

My handbook has the following explanation [ although it mentions two warning lamps on together?]

Definitely gearbox related as gearbox errors are normally a cog shaped light whatever the make of vehicle
