Dont know the full name of it but its like a stability control.Controls traction under accelration and cornering.Floor it in a straight line and it will genrally stop you from spinning.Do it with half lock or full lock on n the crazy thing will stop you from going anywhere.If you want a quick get away its just in reach of ya finger to turn it off while ya hand on gear know.In my 220 it is anyway.
Good thing to have to stop you getting it out of shape.But bloody dangerous to have on if your pulling out in front of a truck and need to get a quick get off.it just bogs you and deliberatly stops you from accelerating.Only way i can put it is it stals you.
If you turn it off light appears on dash(car with skid marks behind it).sometimes ive noticed with some electronic gadgets in the mondeo you do have to switch car off and restart to reset itself dont know why.
