thats not that simple ... because with keyless entry and go the ignition will be on when you are inside the car with the key and doors are closed ... so you don´t need a key anyway ...@JFS
It means that power is only supplied to that outlet when the ignition is in the on position. There are usually a mix of both types of outlets. Outlets that only supply power when the car is on, and those that supply power from the battery even if the ignition is off.
Definitely not the best icon to use. I hope the salesman explains this icon to every buyer as it could be a problem for some people.Probably not the best icon, but maybe it means power to this outlet is switched with the ignition. I have two outlets in my Escape, one constant and one switched with ignition.
