Pcs (Pre-Collision System) (Vehicles With Lexus Safety System + 2.0) - Lexus LS 500 2019 Owner's Manual

PCS (Pre-Collision System)
(vehicles with Lexus Safety
System + 2.0)
The pre-collision system uses a
radar sensor and front camera to
detect objects (P.215) in front of
the vehicle. When the system
determines that the possibility of a
frontal collision with an 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 deter-
mines that the possibility of a frontal
collision with an object 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.217)

move the seatbacks of the front pas-
senger's seat and power rear seats to
the upright position automatically, if
