Lexus Safety System +
■PCS (Pre-Collision System)
The pre-collision system uses a radar sensor and camera sensor to detect vehicles and
pedestrians in front of your vehicle. When th e 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 increase d to help the driver avoid the
collision. If the system determin es that the possibility of a frontal collision with a vehicle or
pedestrian is extremely high, the brakes are au tomatically applied to help avoid the collision
or help reduce the impact of the collision.
