From Lincoln press: Lincoln Navigator combines classic Lincoln design and amenities with the functionality full-size SUV customers demand. For 2010, Navigator's exclusive AdvanceTrac with RSC is joined by standard Trailer Sway Control.
Trailer Sway Control works in conjunction with AdvanceTrac with RSC to determine from the yaw motion of the vehicle if the trailer is swaying and takes measures – such as applying precise braking or reduced engine torque – to help bring both vehicle and trailer under control.
Unlike competitive systems, AdvanceTrac with RSC utilizes a second gyroscopic roll rate sensor to determine the vehicle's body roll angle and roll rate. If the unique roll rate sensor detects a significant roll angle, the system applies additional countermeasures – such as applying brakes to one or more wheels or reducing engine power – to enhance vehicle rollover resistance.
In the event of an accident, Navigator is equipped with the SOS Post-Crash Alert System™, where the horn and emergency flashers are activated in an airbag deployment event. Other safety features include Safety Canopy® side-curtain air bags with rollover detection and dual-stage front air bags that deploy with varying power based on crash severity, the driver’s seat position and safety-belt usage. Front seat-mounted side air bags provide enhanced protection in the event of a side impact, while SYNC with 911 Assist can call for help.
