: For countries/areas specified as Region B (P. 266), the pedestrian detection func-
tion may not be available.
The pre-crash safety system detects pedestrians
based on the size, profile, and motion of a
detected object. However, a pedestrian may not
be detected depending on the surrounding
brightness and the motion, posture, and angle of
the detected object, preventing the system from
operating properly. (P. 277)
