To turn off the stop-start on the FIAT 500 You have two choices. Some years have a button on the dash labeled stop/start, eco, or ESS. Hit it and then You are done. For years that don't have a button, You will need to pull the fuse to the system. To get to the fuse box look to the left of the steering wheel look for a small seam or crack along the dash. Using a screwdriver or prybar You will want to pop this open. On the inside, You will find a bunch of fuses. On the back of the panel that You pulled open, You will see a diagram that will show You what each of the fuses is for. If this is not on the back of the panel then You can also find it in the owner's annual for the vehicle. Once You have figured out which fuse You need simply pull it out. The two sections that stick up should be connected by a thin strip of metal. If this has been broken then the fuse is no good and will need to be replaced. If this strip is there then the fuse is fine and can be popped back in. New fuses will cost You about 10 dollars, so they are pretty cheap.

I left my car on, battery went low. All kinds of warnings came up but it wouldn’t start and wouldn’t recognize the fob. Someone told me to make these warnings disappear I must disconnect the positive side of the battery. I found the fuse and pulled it out. Will try starting it in the morning.

I have just got a fiat 500 and when I go to put it in to first it cuts out and I have never driven a fiat 500 before so I will have to get use to it and it is a good car to drive as I was driving a Dacia sandero
