Subaru Forester EyeSight 2015 Owner's Manual page 7

CAUTION
The characteristics of the stereo cameras are similar to those of human
eyes. For this reason, conditions that make it difficult for the driver to see
in the forward direction have the same effect on the stereo cameras and
make it difficult for the system to detect vehicles, obstacles and traffic
lanes.
Detection by the EyeSight system is limited to objects that are within the
range of the stereo cameras' field of vision. Also, after an object enters the
range of the cameras' field of vision, it may take some time for the system
to detect it as a controllable target and warn the driver.
Under the conditions listed below, it will become more difficult for the sys-
tem to detect the vehicle in front, motorcycles, bicycles, pedestrians and
obstacles on the road and lane markers, and EyeSight may temporarily
stop operating. However, the system will resume operation once these
conditions have improved and the vehicle is driven for a short period of
time.
- Bad weather (for example heavy rain, a blizzard or thick fog). In particu-
lar, the system is more likely to temporarily stop operating when there is
an oil film adhering to the windshield, a glass coating has been applied
or old wipers are used.)
- When affected by strong light from the front (sunlight or headlight
beams, etc.)
- The windshield has become fogged, or snow, dirt, dust or frost has
adhered to it, reducing the stereo cameras' field of view.
- The vehicle is tilted at an extreme angle due to loaded cargo or other
factors.
- When the stereo cameras' field of view is obstructed (for example by a
canoe on the roof of the vehicle)
- When visibility is poor due to sand, smoke or water vapor in the air, or
when the vehicle in front or oncoming traffic causes water, snow, dirt or
other substances to obscure the view
Low objects surrounding the vehicle cannot
be detected.
