Is there a way to have the car beep (loudly) when the lane departure system sees you going out of the lane? in the Kia, the thing beeps (Annoying as ****). But in the Honda, it only shows a message on the dash.

What about beeping when about to hit something?

The sensitivity for the Road Departure Mitigation (RDM) system can be adjusted and auto-braking can be turned off, but there isn't an option to select an audible alert. The main alert Honda provides is the visual alert and steering wheel vibration. Beeping starts only as a last extreme, if no driver feedback is detected.

Thanks for the reply. I did not know it will stop before crossing a double line. That is cool!

Are you also able to explain the difference of the lane widths for Road Departure Mitigation System. I don't really understand which width it should be set at, and what effect the different settings will have.

Thanks!

I think you're asking about the "Narrow" vs "Normal" vs "Wide" vs "Warning Only" settings for Road Departure Mitigation (RDM). The settings change the sensitivity/range that will trigger alert and steering control from the RDM system.

I find that Honda provides more information on the technologies when they first introduce them. The following description comes from the 2018 Clarity manual:

• Normal (default) = steering control starts at the inside lane edge
• Wide = steering control starts at the outside lane edge
• Narrow = steering control starts from further inside the lane edge than Normal setting
• Warning Only = visual "BRAKE" message & tactile (vibration) alert only, no steering torque or brake assist engages when alert occurs

Also of note is that RDM is only active at 45-90 mph when the brakes, turn signal and windshield wipers aren't otherwise running.

Does this affect the LKAS system as well? I don't use the LKAS much with mine because it really seems to hug the shoulder line.

RDM is different from LKAS. RDM has the notification settings mentioned above, which affect how soon the system notifies you of lane drift. The only LKAS configuration I've seen is whether or not it beeps.

RDM alerts / assists if the car is about to drift out of lane. LKAS helps keep the car centered when used with ACC. In theory, LKAS keeps the car centered so RDM won't need to activate.

Both systems use the front camera and are designed to work at 45-90 mph speeds.

What setting do you use for RDM?

I don't use Road Departure Mitigation. When driving I'm darn sure aware of the lanes and the edge of the road, so why let a computer monitor those for me-----and maybe make some corrective action I don't want ?
