I saw those before, I'm pretty sure they are so when at speed cool air passes thru, but when idling and in traffic, they close up so the fan pulls the air in and hot air doesn't backflow out the radiator from the eninge compartment negating the cooling effect. It looks like Nissan put some real thought into this truck!
