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 Jeep Grand Wagoneer doesn’t offer pretensioners for its second-row seat belts.
The LX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Grand Wagoneer doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the LX. But it costs extra on the Grand Wagoneer.
To deliver safety and visibility under dusty conditions the Lexus LX’s backup monitor has a standard rear washer to keep the view clear. A camera washer system costs extra on the Jeep Grand Wagoneer.
Both the LX and Grand Wagoneer 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 Grand Wagoneer’s Rear Cross Path Detection doesn’t automatically brake.
Both the LX and the Grand Wagoneer 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
