The SR5 is the base model but it's not bare-bones. Standard features include cloth upholstery, skid plates, foglights, a backup camera, keyless entry, five 12-volt power outlets and a 120-volt AC power outlet.
Stepping up to TRD Off-Road adds some serious off-road chops in the form of a locking rear differential, wheels that are 0.5 inch wider and a crawl control function. It also offers the optional KDSS suspension.
Premium variants of the SR5 and TRD Off-Road get power-adjustable and heated outside mirrors, premium vinyl upholstery, navigation and an auto-dimming rearview mirror.
Serious off-roaders should consider the TRD Pro, which starts with the TRD Off-Road Premium and adds revised front springs, Bilstein dampers with rear remote reservoirs, Nitto Terra Grappler tires and a front skid plate.
Limited models top the 4Runner range. These models get a Torsen center differential (4x4 models only) plus a host of features to make it better suited to on-pavement use: 20-inch wheels, a sunroof, dual-zone climate control, parking alerts, perforated leather seat upholstery, a 15-speaker premium audio system. Power running boards are optional.
