Honda Road Departure Mitigation System (RDM)

What Is Honda RDM?

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.

How Does RDM Work?

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.

Customize the RDM Settings

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:

  1. Press the info button on the left-hand side of the steering wheel.
  2. Press the up or down arrow buttons until “Vehicle Settings” appears in the instrument panel and then press the ENTER button.
  3. Using the up and down arrow buttons, scroll through the menus until “Driver Assist System Setup” appears in the instrument panel and press the ENTER button.
  4. Once again, using the up and down arrow buttons, scroll until you find “Road Departure Mitigation Setting” and press the ENTER button.
  5. Choose from Normal, Wide, or Warning Only.
    • Normal: RDM will work as intended.
    • Wide: Changes the point at which the system will begin steering assistance.
    • Warning Only: Visual and tactile alerts only with no steering input or braking.
  6. Using the up and down arrow buttons, scroll until you see “Exit” in the instrument panel and press the ENTER button.

Honda RDM vs. LKAS

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.

Which Honda Models Have RDM?

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.

* Road Departure Mitigation only alerts drivers when lane drift is detected without a turn signal in use and can apply mild steering torque to assist driver in maintaining proper lane position and/or brake pressure to slow the vehicle’s departure from a detected lane. RDM may not detect all lane markings or lane departures; accuracy will vary based on weather, speed and road condition. System operation affected by extreme interior heat. Driver remains responsible for safely operating vehicle and avoiding collisions.
