Driving
The system may not detect lane markings and therefore may not keep the vehicle in
the middle of the lane under certain conditions, including the following:
■Environmental conditions
• 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 object s (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.
• Driving at night or in a dark place such as a tunnel (due to low-light conditions,
lane lines or the road surface 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.
• Strong light is reflec ted onto the roadway.
