F31 2013 uk rear net and tensioning strap

Hi guys,



I've just acquired a 2013 f31 and the user manual suggests that I should have a net that divides the boot from the passenger cabin. It looks like this: http://ift.tt/1hNINkE



And a tensioning strap like this: http://ift.tt/1hNIOoT



Should I have these accessories as standard? If so, I will be giving the dealer a call as I don't have them! It's an m sport if that makes a difference.
