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

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. (
