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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
