PCS (Pre-Collision System)

The pre-collision system uses a
radar sensor and front camera to
detect objects (P.211) 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.213)
Detectable objects
The system can detect the following:
 Vehicles

System functions
Pre-collision warning
■
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage will be displayed on the
multi-information display to urge the
4-5. Using the driving support systems
driver to take evasive action.
Pre-collision 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.
Pre-collision braking
■
If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
Suspension control (if equipped)
■
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension Sys-
tem (P.278) will control the damp-
ing force of the shock absorbers to
help maintain an appropriate vehicle
posture.
