Where is the manufacture date on a 2012 Chevrolet Captiva?

To be most clear about where to find it, you cannot see it from outside the car or inside the car when the driver's door is closed. You can only see it when the driver's door is open, exposing the door jamb of the car. Look along the side of the door itself or along the door frame of the car to find it. It will either be a sticker or a thin plate with the information you seek. It's possible it may have been removed at some point. Sometimes the sticker or plate is found under the hood of the car near the radiator on the frame of the car.

In Australia, I found it on the passenger side front door pillar
