PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
The pre-crash safety system uses a radar sensor and camera
sensor to detect vehicles and pedestrians
*1 in front of your vehi-
cle. When the system determines that the possibility of a frontal
collision with a vehicle or pedestrian 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 possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied
*2 to help avoid the collision or help reduce the
impact of the collision.
The pre-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. (P. 372)
*1: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available. Contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional for
details.
*2: Depending on the region in which the vehicle was sold, the pre-crash
braking function (automatic braking function) may not be available. Con-
tact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for details.
