uuWhen DrivinguLane Keeping Assist System (LKAS)
Driving
■
The LKAS may automatically be canceled when:
• The camera temperature gets extremely high or low.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• The ABS or VSA® systems engage.
The beeper sounds if the LKAS is automatically canceled.
The system may not detect lane markings and therefore may not keep the vehicle in
the middle of a lane under certain conditions, including the following:
■
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 windshield.
