For enhanced safety, the front seat shoulder belts of the Lincoln Navigator L are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Rolls-Royce Cullinan doesn’t offer height-adjustable seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Navigator L are reminded to check the back seat if they opened the rear door before starting out. The Cullinan doesn’t offer a back seat reminder.
The middle row seatbelts optional on the Navigator L inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The Cullinan doesn’t offer inflatable seatbelts.
Both the Navigator L and the Cullinan have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, 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, driver alert monitors and available all wheel drive.
