Shoota, Mr Datsun gave your ute a key and a door handle. This is to open the door and get in.

You will also notice on the inside of the door there is a silver thing with a black knob on it, this is the window winder, it is used to wind the window up and down. It is also part of the air conditioner, when it is hot you wind the window down and when it is cold you wind the window up.

All pretty simple.
