Trailer Sway Control is standard on the Navigator, along with a Roll Stability Control stability control system, anti-lock brakes, and safety canopy and side-impact airbags, plus a child-tether system, driver-seat position sensor, crash severity sensor, and SOS post-crash alert system.
The Navigator hasn't yet been rated by the Insurance Institute for Highway Safety (IIHS), or by the federal government's completely revised testing and rating system that began for 2011. But under the former system, the National Highway Traffic Safety Administration (NHTSA) gave the 2010 Navigator a top five-star rating in both frontal and side-impact tests.
Some drivers might find outward visibility challenging in the 2011 Navigator because of its sheer height. A rearview camera system is optional, though it's only offered as part of pricer option packages.
