The fine print for the warranty says "up to 2 additional years" so 1 year manufacturers warranty becomes 3, 2 year manufacturers warranty becomes 4 and 5 year manufacturers warranty becomes 7. If the item has a 5 year or longer manufacturers warranty then you need to register the item with them.
Note that when you submit a warranty claim they are going to want 4 items ... A copy of the original bill of sale, a copy of the monthly credit card statement showing the entire purchase was put on the credit card, a copy of the front page of the owners manual and a copy of the warranty page (with some items that is that loose slip of paper that some people throw out). Some products are excluded - like automobile and boat parts...
