(Diono is extremely cautious... kids getting whiplash is almost a nil-event, but they don't want you to sue them if you happen to not have vehicle head support behind their booster headrest, really only Diono and Dorel are the only companies with such rules, and it's weird...but basically just keep your vehicle headrest on behind the booster, fortunately most newer cars HAVE headrests...sometimes they push the booster so far forward there's a gap behind the back, and it's an untested scenario, so they recommend you use a different seating position or take the back off the booster...I don't think Subaru or your minivan are known to be problems, at any rate, fortunately).
