◆
Pre-collision 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-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.

: If equipped
The pre-collision 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 driver 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-collision system can be disabled/enabled and the warning timing can
be changed. (
