I was told in another forum that this is the "shipping" pressure and that the dealers are supposed to reduce it on receiving. They are also supposed to put rubber plugs in the shipping tie-down points on the frame. Mine didn't have those either.
This is true on both items. They are suppose to be part of the Pre-Delivery Inspection. Those plugs help reduce road noise transmitted through the body. Makes a big difference on our cars.
