For enhanced safety, the front and middle seat shoulder belts of the Lexus LX 570 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the LX 570. But it costs extra on the QX80.
