In addition to the 3.3L engine, 2004 V6-powered models were equipped with a new 5-speed automatic transmission, replacing a 4-speed automatic transmission, while the 4-cylinder models continue to use the old 4-speed automatic transmission. This year also saw the introduction of the optional third row seat. The unibody was slightly modified behind the second row seats to include a depression on the trunk floor to accommodate the optional third row seating. On models without third row seating, the depression on the trunk floor was turned into a storage compartment. (Prior to 2004 the spare tire was accessible from inside the vehicle where the third row seating would subsequently be located; beginning in 2004 the spare tire is accessible from underneath the vehicle.)
