Road Departure Mitigation (RDM)

What is Road Departure Mitigation (RDM)?

RDM is designed to alert and assist the driver if the vehicle is about to unexpectedly leave the road. The system will apply strong steering correction and braking force to help stop the vehicle before a serious accident occurs.


How does Road Departure Mitigation (RDM) work?

When RDM is activated, a camera mounted at the top centre of the windshield detects lane markings to monitor the vehicle's position on the road at speeds between 72-145 km/h. If the vehicle drifts from the intended lane without the use of a turn signal, a visual warning appears in the MID, accompanied by an audible chime and subtle steering assist to help the driver guide the vehicle back to the centre of the lane.

If the system determines that its steering input is insufficient to keep the vehicle on the road, it may also apply braking force. Braking is applied only when the lane markings are solid continuous lines. The system cancels assist operations when the driver turns the wheel. Adjusting RDM Settings To adjust RDM alert settings, follow these steps:

Customer Benefits

RDM is helpful during long-distance highway driving when driver fatigue is more likely to occur. RDM helps keep the driver aware of the road ahead and the vehicle within the intended lane on the road. RDM not only helps keep the driver safe but surrounding motorists as well.
