For enhanced safety, the front and rear seat shoulder belts of the Mercedes G-Class 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. The Lincoln Navigator L doesn’t offer pretensioners for its second-row seat belts.
The G-Class’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Navigator L doesn’t offer pre-crash pretensioners.
Both the G-Class and Navigator L have rear cross-traffic warning, but the G-Class has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Navigator L’s Cross-Traffic Alert doesn’t automatically brake.
Both the G-Class and the Navigator L have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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.
