: Applicable to vehicles designed for regions that detection of pedestrians and/or bicyclists
is possible (P.242)
The system may not operate in the following situations:
● If a 12-volt battery terminal has been disconnected and reconnected and then the vehicle
has not been driven for a certain amount of time
If the shift lever is in R
●
● When the VSC OFF indicator is illuminated (only the pre-collision warning function will
be operational)
Object detection function
■
The system detects objects based on their
size, profile, motion, etc. However, an object
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.248)
The illustration shows an image of detect-
able objects.
