Yes I can see the white plastic tap. Looks like the splash guard will need come off to access it. Is this a security feature or did they make access simpler in later models? Its really quite simple mate, just take off the splach guard, or even just a few screws to be able to bend the front down, and turn on the tap. Im guessing its behind the guard for protection against an outside forces/objects accidently coming in contact with and switching on your tap draining your coolant..
