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 warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆Pre-crash brake assist
When the system determines that the possibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
∗: If equipped
The pre-crash safety system uses a radar sensor and camera sensor to detect
vehicles and pedestrians
*1 in front of your vehicle. When the system deter-
mines that the possibility of a frontal collision with a vehicle or pedestrian is
high, a warning operates to urge the dr iver 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 automatically 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 warning timing
can be changed. ( →P. 2 9 6 )
*1: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact any authorized Lexus 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 func-tion (automatic braking function) may not be available. Contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional for
details.
