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 the sy stem 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 pote ntial brake pressure is increased 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.
■ LDA (Lane Departure Alert with steering control)
→ .P. 28
■Automatic High Beam
→ P. 18
■Dynamic radar cruise control
→ P. 25
*: Depending on the region in which the vehicl e was sold, the pedestrian detection function
may not be available. For details, refer to the “OWNER’S MANUAL”.
The Lexus Safety System+ consists of the fo llowing drive assist systems and contributes
to a safe and comfortable driving experience:
