be restored. It is necessary to register

facial traits. In the following situations, face
information may not be able to be regis-
tered or identified correctly:
● When a part of the driver’s face (eye-
brows, eyes, nose, or mouth) is not visible
● When the driver is wearing glasses/sun
glasses, a face mask, muffler, etc.
● When the driver is not facing front
● When part of driver’s face is covered
with hair, beard, a hand, clothes, jewelry,
etc.
● When the driver is closing eyes
● When a non-registered driver is a twin,
etc. with a registered driver, whose face
looks quite alike with each other

PCS (Pre-Collision System)
The pre-collision system uses sen-
sors to detect objects (P.234) in
the path of the vehicle. When the
system determines that the possi-
bility of a frontal collision with a
detectable object is high, a warning
operates to urge the driver to take
evasive action and the potential
brake pressure is increased to help
the driver avoid the collision. If the
system determines that the possi-
bility of a collision is extremely high,
the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. (P.243)
WARNING
■ For safe use
● Driving safely is solely the responsibil-
ity of the driver. Pay careful attention
to the surrounding conditions in order
to ensure safe driving.
Never use the pre-collision system in
place of normal braking operations. This
system cannot help avoid or reduce the
impact of a collision in every situation.
Over-reliance on this system to drive the
vehicle safely may lead to an accident
resulting in death or serious injury.
