Safety

There's a standard brake-based stability control system with rollover mitigation, and a tire pressure monitoring system, both of which are must-haves for large SUVs. Tire pressure is always important to keep an eye on, and even more so with SUVs. There are three rows of side curtain airbags, along with seat-mounted side airbags for the driver and front passenger.
The National Highway Traffic Safety Administration gave the Navigator a five-out-of-five-star frontal crash-test rating and a four-out-of-five-star rollover rating for the four-wheel-drive model. The Navigator has not been crash tested by the Insurance Institute for Highway Safety, which has a more stringent testing process than NHTSA.
