Unlock the doors and windows. Do whatever you can to accomplish this critical step. Even if you cannot open the door yourself, unlocking the doors will give bystanders or rescuers a good shot of getting you out of the burning vehicle quickly.
Get your seat belt off. This must be done quickly so the heat of the fire does not fuse the metal of the buckle to its anchor. If the metal is too hot to touch, use a piece of cloth to cover your hand so that you can release the buckle. If the buckle won't release, push the shoulder strap over your head and try lifting your legs out from underneath the waist strap.
Kick out a window. If you cannot get the door open, the next best thing is to kick out a window. Getting a window open will allow smoke to exit the car and will also give you an escape route. Use both feet against a side window, if possible, to shatter and then pop the window out of the frame.
