wipers

There's a button on the left side for what appears to be automatic wipers. I finally got to drive in rain in SoCal and it doesn't appear to do anything. Does anyone know how it works? If it's not automatic wipers, then what is it for? The button light comes on but I don't notice anything...

I don't have the car yet--- so maybe someone who does will be kind enough to answer a few questions I have about operating the CT: 1. When the keyless entry is set to unlock only the driver's door (which is safe); is there an easy way to unlock the passenger doors by pulling on the handle twice...
