How to use Road Departure Mitigation (RDM)

August 28th, 2018 by

Road Departure Mitigation System helps to ensure your vehicle only leaves a detected lane, or roadway altogether when the driver intends to.

• If your vehicle drifts too close to detected lane markings while driving between 45MPH and 90MPH without a turn signal activated, the system alerts you with visual and audible lane-departure warnings.

•  If no steering correction is applied, the system can apply steering torque to help keep the vehicle in the detected lane when you start to cross over the lane line or road edge.

•  If the system determines that steering input is insufficient to keep the vehicle on the roadway, it may apply braking to help keep it from departing the road altogether.
