For enhanced safety, the front and second-row seat shoulder belts of the Lexus LX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Lincoln Navigator doesn’t offer pretensioners for its second-row seat belts.
Both the LX and Navigator have rear cross-traffic warning, but the LX has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Navigator’s Cross-Traffic Alert doesn’t automatically brake.
Both the LX and the Navigator have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
