Pre-collision braking
●
Detectable objects
Vehicles
Bicyclists and pedestrians
The system may not operate in the following situations:
●
If a battery terminal has been disconnected and reconnected and then the vehicle has not
been driven for a certain amount of time
●
If the shift position 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.220)
The illustration shows an image of detect-
able objects.
Cancelation of the pre-collision braking
■
If either of the following occur while the
pre-collision braking function is operating, it
will be canceled:
The accelerator pedal is depressed
●
strongly.
●
The steering wheel is turned sharply or
abruptly.
■
Conditions under which the system may
operate even if there is no possibility of a
collision
●
In some situations such as the following,
the system may determine that there is a

• 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 detectable object or other
object by the roadside at the entrance of
a curve
