Pedestrian detection function
*2
The pre-collision system detects pedestri-
ans based on the size, profile, and motion of
a detected object. However, a pedestrian
may not be detected depending on the sur-
rounding brightness and the motion, pos-
ture, and angle of the detected object,
preventing the system from operating prop-
erly. (

P.194)
*2
: For countries/areas specified as Region
B (

P.188), the pedestrian detection
function may not be available.
