Oh, ok! I never noticed that it was a setting on my screen. I will try this in the morning.Look at the screen you posted... in the lower left corner is an adjustment for Amps. It won't let you go past 16 in this case. If you were plugged into a different source, that adjustment would show the max allowable.
If the car had automatically set the Amps to 2, it was most likely due to a glitch in your elec service - to protect the car. Try setting it back - the car won't let you hurt it.
