Just curious. What does the "smart key" feature do? I see an icon left on the left of the dash with a car and a key inside of it with a blinking light. Does this mean that a key is near?

Also, how do I disable it? Is it the **** under the dash near the gas pedal?

 

Smart Key allows you to keep your key in your pocket/purse (your choice :-), walk up to your car, unlock it, get in, and start it all without digging it out. Also, open the trunk. I love it.
Sorry, I'm not near my Owner's Manual, so cannot answer your other questions.
