Lane Keep Assist
58
Continued from previous page
- Frozen roads, snow-covered roads or other slippery road surfaces
The tires may spin, causing loss of control of the vehicle.
- When entering a sharp curve into an interchange or junction, or a service
area, parking area, toll booth or other facilities.
- When there are changes in brightness, such as at a tunnel entrance or
exit.
- When visibility is poor due to sand, smoke or water vapor blowing in the
wind, or when the vehicle in front or oncoming traffic causes water,
snow, dirt or dust to obscure the view.
- When there is snow, frost, dirt or dust on the windshield or it is clouded.
- When water droplets from rain or dirt have not been fully wiped off on the
windshield.
It may not be possible to detect the lane, making correct control impossi-
ble.
- When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle).
The stereo cameras may have difficulty detecting the objects under the follow-
ing conditions and the system may not operate properly.
- When driving at night or in a tunnel without the headlights on.
- When light is poor in the evening or early morning.
- In bad weather (for example, rain or snow)
- The distance between your vehicle and the vehicle in front is short, mak-
ing it difficult to detect lane markings.
- When a vehicle intruded from an adjacent lane or the vehicle in front
changed lanes.
- The shape of a curve in the road suddenly changes.
- Shadows of guardrails or similar objects are overlapped on the lane
markings.
- When your vehicle is exposed to a strong light from the front (backlight
from the sun, headlights, etc.).
- The width of a lane is narrow.
- The stereo cameras may have difficulty detecting the lane due to the per-
formance of the cameras.
• There are no lane markings or they are very worn.
• The lane markings are painted in yellow.
• It is difficult to detect lane markings because they are similar in color to
the road surface.
• The lane markings are drawn in double.
• The width of lane markings is narrow.
• The indicated lines for the area are touched to walls and poles.
- The shape of lane markings suddenly changes (entrance/exit of a curve,
crank and S-shaped road, etc.).
