In 2003, for the 2004 model year, in addition to the 3. 3-liter engine, V6-powered models were equipped with a new five-speed automatic transmission, replacing the four-speed automatic transmission, while the inline-four models continued to use the old four-speed. This year also saw the introduction of the optional third row seat allowing for two additional passengers. The center console, which was previously exclusive to the top trim level, is now standard across all trims. The unibody was slightly modified behind the second row seats to include a depression in the trunk floor able to accommodate the optional third row seating. On models without third row seating, this depression 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). Subtle changes to the front grille, front and rear bumpers, headlights and taillights (LED taillights on later hybrid models) round-out the major changes for the 2003 mid-cycle refresh.
