On your key fob, push the "LOCK" button together with the "UNLOCK", "TRUNK" or "PANIC" button for about 5 seconds with the engine switch off. As you do this, look at the multi-information display in the dashboard. It will show you which setting you have selected. It will change from Unlocking the Drivers door, to Unlocking the side doors, to Unlocking a single door, to Unlocking all doors. (The icon will be a car with 4 doors open).
I hope that helps you out.
