Significant changes from the second generation models include a larger body on a longer wheelbase, increased interior space, increased cargo space, dual airbags, ABS, lift-up tailgate, coil-spring suspension all around, rack and pinion steering, and aerodynamic contour designed glass headlights. Additionally, Hilux Surf versions immediately moved to 16-inch wheels and gained a center differential, enabling the use of four-wheel drive on hard surfaces without complication for the first time. The prior system was retained to give on-the-fly shifting between rear- and four-wheel drive as before. The new 4Runner was also available with a factory installed selectable electric locker in the rear differential, a first for the 4Runner but available since 1993 in the Toyota Land Cruiser.
