System Limitations

The LKA system may activate prematurely even if the vehicle has not departed from its intended lane, OR the LKA system may fail to warn you if the vehicle departs from its intended lane under the following circumstances:

When the lane and road conditions are poor

• The lane markings are difficult to distinguish from the road because they are covered with dust or sand.
• The color of the lane markings is difficult to distinguish from the road.
• The road surface has markings similar to lane markings that are accidentally detected by the camera.
• The lane markings are faint or damaged.
• The lane markings are merged or divided (e.g., barrier gate).
• The number of lanes increases or decreases, or lane markings intersect in a complex way.
• There are more than two lanes ahead on the road.
• The lane marking is very thick or thin.
• The lane is very wide or narrow.
• The lane markings ahead are not visible due to rain, snow, water on the road, damaged or painted road surface, or other factors.
• Shadows on the lane markings at the median strip, trees, guardrails, noise barriers, etc.
• The lane markings are complex or the structure replaces the lines, e.g., construction zone.
• There are crosswalk signs or other symbols on the road.
• The lane markings in a tunnel are soiled with oil, etc.
• The lane suddenly disappears, e.g., at an intersection.

When external conditions interfere

• The brightness outside changes suddenly, e.g., when entering or exiting a tunnel or passing under a bridge.
• External brightness is too low, for example, when headlights are not on at night or the vehicle is driving through a tunnel.
• There are roadside structures such as concrete barriers, guardrails, and reflector posts that are accidentally detected by the camera.
• When light from a street lamp or an oncoming vehicle is reflected on a wet road surface, such as a puddle.
• The forward field of view is limited by sun glare.
• The distance between your vehicle and the vehicle ahead is not sufficient for the system to detect the lane markings or the vehicle ahead based on the lane markings.
• Driving on a steep slope, hill, or winding road.
• Adverse road conditions cause excessive vehicle vibration while driving.
• The area around the inside rearview mirror is hot due to direct sunlight, etc.

When forward visibility is poor

• The windshield or camera lens is covered with dirt or debris.
• The windshield is fogged; clear view of the road is obstructed.
• Placing objects on the instrument panel, etc.
• The sensor cannot detect the lane due to fog, heavy rain, or snow.

WARNING

The Lane Keeping Assist (LKA) system is a system that helps the driver prevent unintended lane departure. However, the driver must not rely solely on the system and must always take necessary actions for safe driving.
