Model year changes
In early 2003, Toyota added an optional Appearance Package for the SR5 model that included color-keyed cladding, bumpers, and liftgate trim. In April 2003, Toyota made the Appearance Package, along with the previously optional fog lamps, running boards, and 16-inch aluminum wheels, standard on the SR5. The Sport Edition also added black running boards and color-keyed trim, replacing the grey cladding and silver-painted grille, door handles and liftgate trim.
In late 2003 (for the 2004 model year), a Tire Pressure Monitoring System was added as standard equipment. A 3rd row seat became optional on the SR5 and Limited models.
In 2004 (for the 2005 model year) enhancements were brought to the optional V8 engine and a 5-speed automatic was made standard on the V6 model. Slight changes were made to the exterior including color-keyed bumper trim (replacing the silver painted trim on all colors except Dorado Gold) on the SR5 and Limited; a chrome grille on the SR5; a black roof-rack and running boards (replacing silver) on the Limited; and a redesigned rear spoiler. A Salsa Red Pearl scheme was also introduced for all trim levels, although a similar color scheme was available for third generation models.
Facelifted Toyota 4Runner Sport Edition 4WD (US)
2005 (for the 2006 model year) marked the fourth generation's mid-cycle refresh. The changes included revised front and rear bumpers; a reworked grille; new projector-beam headlamps and LED tail lamps; additional chrome trim on the SR5 model; and a smoked-chrome grille with tubular roof-rack and step bars on the Sport Edition. The revised front bumper features circular fog lights and a relocation of the turn-signals to the headlamp assembly. The redesigned bumper eliminates the rear bumper reflectors. MP3 playback capability and an auxiliary input jack were added to all audio systems. In addition, the Limited model was further differentiated from the other trim levels with the addition of unique 18" wheels and a seat memory system. Shadow Mica was added as a color option.
In 2006 (for the 2007 model year), the 4Runner remained unchanged.
In 2007 (for the 2008 model year), the 4Runner received standard rollover sensing side curtain airbags and front row side torso airbags, a switch to disable Vehicle Stability Control, slightly modified front grille design, refinements in the Tire Pressure Monitoring System, and some changes in the seatbelt warning system and brake system control. An Urban Runner Package was also available on the Sport Edition V6 4x4, which added an in dash Tom Tom navigation system, alcantara inserts in both the front and back seats with dark leather bolstering, the 18" Limited style wheels, a color-keyed front grill and a double-decker cargo system.
In 2008 (for the 2009 model year) the 4Runner remain unchanged. A Trail Edition package offered an electronic locking rear differential, Advanced Traction Control (A-TRAC) and Bilstein dampers.
Later models offered a DVD Rear Seat Entertainment System (RSES) which used a nine-inch LCD screen and two wireless headphones.
