4-5. Using the driving support systems
O Intersection right/left turn assistance (pre-collision braking)
When the turn signal lights are not flashing, support for turning left or right at an intersection
which targets oncoming vehicles does not work.
Q Object detection function
The system detects objects based on their
size, profile, motion, etc. However, an
object 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.232) The illustration shows
an image of detectable objects.
Q Conditions under which the system may
operate even if there is no possibility of a
collision
O In some situations such as the following,
the system may determine that there is a
possibility of a frontal collision and oper-
ate.
• When passing a detectable object, etc.
• When changing lanes while overtaking a
detectable object, etc.
• When approaching a detectable object
in an adjacent lane or on the roadside,
such as when changing the course of
travel or driving on a winding road
• When rapidly closing on a detectable
object, etc.
• When approaching objects on the road-
side, such as detectable objects, guard-
rails, utility poles, trees, or walls
• When there is a detectable object or
other object by the roadside at the
entrance of a curve
