The only way to see the max tow weight is to look at the vin plate (on boot floor) that fiat has stamped the cars weights onto, this is the only way to tell the legal weight, don't go on the handbook or even the cars log book, if you have a bump or are stopped by the police etc they will only look at FIATS plated maximum on YOUR car. So there will be 4 sets of weights stamped onto the plate, first number is maximum car weight, 2nd number is maximum train weight, ie, car plus trailer, last 2 are max axle weights, (if there's only 3 sets then you cannot tow anything with this car, and your insurance will be invalid), so all you need to do subtract the first number from the second and you have the maximum tow weight for YOUR car. Hope this helps, and only go on the VIN PLATE.
