Honda CR-V: Road Departure Mitigation (RDM) System / RDM Conditions and Limitations

The system may not properly detect lane markings and the position of your vehicle under certain conditions. Some examples of these conditions are listed below.

Environmental conditions

• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interior of the front windshield.

Roadway conditions

• Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks, reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road repairs or old lane markings.
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection or crosswalk).
• The lane markings are extremely narrow, wide, or changing.
• The vehicle in front of you is driving near the lane lines.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving on rough or unpaved roads, or over bumpy surfaces.
• When objects on the road (curb, guard rail, pylons, etc.) are recognized as white lines (or yellow lines).
• When driving on roads with double lines.

Vehicle conditions

• Headlight lenses are dirty or the headlights are not properly adjusted.
• The outside of the windshield is streaked or blocked by dirt, mud, leaves, wet snow, etc.
• The inside of the windshield is fogged.
• The camera temperature gets too high.
• An abnormal tire or wheel condition (wrong sized, varied size or construction, improperly inflated, compact spare tire, etc.).
• The vehicle is tilted due to a heavy load or suspension modifications.
• When tire chains are installed.
• The vehicle is towing a trailer.
