In addition to the usual array of airbags, anti-lock brakes and stability control, the 2007 Lincoln MKX features other safety devices, such as standard tire pressure monitoring. Optional adaptive front headlights are linked to steering inputs, “turning” around corners with the vehicle and illuminating up to 36 more feet of roadway than conventional headlights, according to Lincoln. DVD-based navigation is trilingual, providing voice directions in English, Spanish or French. The rear DVD entertainment includes an eight-inch flip down screen or, in models with the panoramic sunroof, screens in the back of the front headrests. The available 600-watt 14-speaker audio system comes with THX II-certification. The MKX also has four power points and an MP3 audio jack.
