Problem with camera loading different scenes

I have a weird problem when I play my game. I have a pause menu and main menu to select different scenes. First time when opening the scene the camera follows the vehicle like its suppose to, but if I pause, go to main menu, select a different level (new scene) the camera stays static and does not follow the vehicle. Now, if I press pause, unpause, in the scene, the camera will start following the vehicle like its suppose.

Any help to get this straitened out that would be great! Im not sure what part of the code you'll need for this as Im not sure its in the camera script or the pause script?
