The Road Departure Mitigation System, or RDM, is a driver-assist feature from the Honda Sensing® suite that’s designed to enhance driver awareness and safety on Iowa’s roadways. RDM can provide moderate steering assistance if your vehicle crosses detected lane markings without a turn signal, bringing you back to the center of your lane, and can even apply the brakes to help your vehicle from leaving the road completely. Join Vern Eide Honda Sioux City as our staff explains how the Road Departure Mitigation System works, RDM versus LKAS, and which Honda models have RDM.
Honda’s Road Departure Mitigation System uses a windshield-mounted camera to detect lane markings. If your vehicle begins to leave a detected lane without signaling, a visual alert will appear in the instrument panel and the steering wheel will vibrate. Additionally, the electric power steering will help prevent your Honda from unintentionally drifting over lane markings on the edge of the road. If RDM determines that steering input alone will not keep your vehicle on the road the system can also apply braking—provided lane markings are visible.
How do you customize the settings of the Road Mitigation Departure System? Below, is a step-by-step guide locating the RDM menu and adjusting the settings:
What is the difference between Honda RDM and LKAS? While these Honda Sensing features may seem similar, they do have a few distinct differences. For instance, while the Lane Keeping Assist System (LKAS) is designed to keep your vehicle centered in a detected lane, RDM will help prevent you from drifting out of a lane and/or off the road entirely. Another significant difference between these two driver-assist features is LKAS needs to be activated manually while RDM can be kept on all the time. RDM has a toggle switch that retains its setting regardless of the vehicle being turned off and you can adjust its sensitivity in the settings menus. Meanwhile, LKAS has a steering wheel switch that must be re-enabled each time your vehicle is started.
Why are Honda SUVs, cars, minivans, and trucks considered to be some of the best cars for families? The automaker’s commitment to safety is stronger than ever, as almost every new Honda vehicle is now standard equipped with the Honda Sensing suite and Road Departure Mitigation. Below is a list of Honda vehicles outfitted with RDM.
RDM is standard equipped on all 2021 Accord trim levels.
