Driver Attention Warning

The driver should be careful in the following situations where the system may not operate properly when lane marking recognition is poor or limited:

When the lane and road conditions are poor

• Lane markings or road edge are difficult to distinguish from the road when they are covered with dust or sand.
• The color of the lane markings is difficult to distinguish from the road.
• Something similar to lane markings is present.
• Lane markings or road edge are faded or damaged.
• The number of lanes increases/decreases or lane lines intersect (passing through a toll gate/toll booth, merged/divided lane).
• There are more than two lane markings.
• The lane marking is very thick or thin.
• Lane markings or road edge are not visible due to snow, rain, stains, puddles, or other factors.
• Shadows on lane markings or road edge caused by median strips, guardrails, noise barriers, and others.
• When lane markings are complex or the construction replaces lines, such as at a construction site.
• There are crosswalk signs or other symbols on the road.
• The lane suddenly disappears, e.g., at an intersection.
• Lane markings or road edge in a tunnel are covered with dirt or oil, etc.
• The lane is very wide or narrow.

When external conditions interfere

• Outside brightness changes suddenly when entering/exiting a tunnel or passing under a bridge.
• Headlights are not turned on at night or in a tunnel, or the illumination level is low.
• There is a guardrail on the road.
• Light from street lights, the sun, oncoming vehicles, etc. is reflected from water on the road.
• When strong light shines from the opposite direction as you drive.
• The road surface is uneven.
• The distance to the vehicle ahead is very short, or the vehicle ahead has discs obscuring the lane line or road edge.
• You are driving on a steep slope or a sharp curve.
• The vehicle is vibrating excessively.
• The temperature near the interior rearview mirror is very high due to direct sunlight, etc.

When forward visibility is poor

• The camera lens or windshield is covered with foreign material.
• The sensor cannot detect the lane due to fog, heavy rain, or snow.
• The windshield is fogged up due to humid air inside the vehicle.
• Something is placed on the airbag cover, etc.

WARNING

The Lane Keeping Assist System is a system that helps prevent the driver from unintentionally leaving the lane. However, the driver must not only rely on the system but always take necessary actions for safe driving.
