Honda Civic Hatchback 2022 Road Departure Mitigation Limitations User Manual
Road Departure Mitigation Limitations
The system may not properly detect lane markings (in white or yellow), the outer edge of the pavement (into grass or gravel border) or an oncoming vehicle under certain conditions. Some examples of these conditions are listed below.
- There is little contrast between lane lines and the roadway surface.
- Driving in bad weather (rain, fog, snow, etc.).
- Driving on a snowy or wet roadway.
- Driving into low sunlight (e.g., at dawn or dusk).
- Shadows of adjacent objects (trees, buildings, guard rails, vehicles, etc.) are parallel to white (or yellow) lines.
- Sudden changes between light and dark, such as the entrance or exit of a tunnel or the shadows of trees, buildings, etc.
- Strong light is reflected onto the roadway.
- Driving at night or in a dark place such as a tunnel (due to low-light conditions, lane lines, the road surface, or oncoming vehicles may not be illuminated).
- The distance between your vehicle and the vehicle ahead of you is too short, and lane lines and the road surface are not visible.
- The outer edge of the road is bordered by objects, materials, etc. other than grass or gravel.
- 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, such as at an intersection or crosswalk.
- The lane markings are extremely narrow, wide, or changing.
- Part of the lane markings are hidden by an object, such as a vehicle.
- The road is hilly or the vehicle is approaching the crest of a hill.
- Your vehicle is strongly shaken on uneven road surfaces.
- When objects on the road (curb, guard rail, pylons, etc.) are recognized as white (or yellow) lines.
- Driving on rough or unpaved roads, or over bumpy surfaces.
- Driving on roads with double lane lines.
- Driving on snowy or slippery roads.
- Passing through an exit or an interchange.
- The pavement is only partially visible due to snow or puddles on the road.
- Driving on unpaved or rutted roads.
- White (or yellow) lines are not recognized correctly due to road conditions such as curves, twists, or hills.
- When lighting is weak due to dirt covering the headlight lenses, or there is poor visibility in a dark place due to the headlights being improperly adjusted.
- The front of the camera is covered by dirt, fog, rain, mud, wet snow, seals, accessories, stickers, or film on the windshield.
- Driving at night or in a dark place (e.g., a tunnel) with the headlights off.
- When the driver operates the brake pedal and steering wheel.
- There is residue on the windshield from the windshield wipers.
- An abnormal tire or wheel condition (incorrect sizes, varied sizes or construction, improperly inflated, compact spare tire, etc.).
- The vehicle is tilted due to heavy load in the cargo area or rear seats.
- Tire chains are installed.
- The suspension has been modified.
Examples of limitations on detection due to the condition of oncoming vehicles
- The oncoming vehicle or vehicle ahead of you is sideways.
- The oncoming vehicle jumps out in front of you.
- When the oncoming vehicle blends in with the background, preventing the system from recognizing it.
- The headlights of an oncoming vehicle are lit on one side or not lit on either side in a dark place.
- The distance between your vehicle and the oncoming vehicle is too short.
- Part of the oncoming vehicle is not visible due to the vehicle ahead of you.
- There are multiple oncoming lanes or turning lanes.
- The vehicle in the adjacent lane is parked or moving at an extremely slow speed.
Examples of other limitations on detection or system operation
- When the oncoming vehicle is specially shaped.
- When the camera cannot correctly identify the shape of the oncoming vehicle.
With Little Chance of a Collision
The Road Departure Mitigation system may activate in the below conditions.
- When driving through curves, your vehicle comes to a point where an oncoming vehicle is right in front of you.
Traffic Sign Recognition System
Reminds you of road sign information, such as the current speed limit your vehicle has just passed through, showing it on the gauge.
How the System Works
When the camera located behind the rearview mirror captures traffic signs while driving, the system displays the ones that are recognized as designated for your vehicle. The sign icon will be displayed until the vehicle reaches a predetermined time and distance. If the system does not detect any traffic signs while you are driving, the sign icon will not be displayed.
The sign icon also may switch to another one, or disappear when:
- The end of the speed limit or other designated limit is detected.
- You make a turn with a turn signal at an intersection.
Not all signs may be displayed, but any signs posted on roadsides should not be ignored. The system does not work on the designated traffic signs of all the countries you travel to, nor in all situations. Do not rely too much on the system. Always drive at speeds appropriate for road conditions.
Never apply a film or attach any objects to the windshield that could obstruct the camera’s field of vision and cause the system to operate abnormally. Scratches, nicks, and other damage to the windshield within the camera’s field of vision can cause the system to operate abnormally. If this occurs, we recommend that you replace the windshield with a genuine Honda replacement windshield. Making even minor repairs within the camera’s field of vision or installing an aftermarket replacement windshield may also cause the system to operate abnormally. After replacing the windshield, have a dealer recalibrate the camera. Proper calibration of the camera is necessary for the system to operate properly. The traffic sign recognition system is not activated for about 15 seconds after the engine starts.
You can read about handling information for the camera equipped with this system. You can turn the traffic sign recognition system on and off.
To help reduce the likelihood that high interior temperatures will cause the camera’s sensing system to shut off, when parking, find a shady area or face the front of the vehicle away from the sun. If you use a reflective sun shade, do not allow it to cover the camera housing. Covering the camera can concentrate heat on it.
If your vehicle exceeds the detected speed limit, an icon representing the speed limit sign for the current area will blink in the display.
The system’s ability to accurately notify the driver of the speed limit is dependent on certain conditions such as the units displayed on the traffic sign as well as the speed and direction of travel of the vehicle. In some cases, the system may display false warnings or other inaccurate information. Traffic Sign Recognition System Conditions and Limitations P. 594
The unit for speed limits (mph or km/h) varies from country to country. Just after entering a country whose unit differs to the one of the country from which you came, Traffic Sign Recognition System may not work correctly.
