Heated jets have a two wire plug attached to them and non heated ones don’t but you can see the second tube between bonnet and van so I would say you do have them, they should be standard with LED headlights
You can feel a minor amount of warmth on the jet but it’s best felt on the reverse side which faces into the bonnet
The jets are very easy to remove just lift the bonnet and pull the edge and the whole thing just clicks out, fire up the van for a minute or two first to allow them to warm up and you should be able to feel it but it is only slight don’t expect them to feel hot to the touch
