■
Driver monitor system (if equipped)
When the system determines that there is a possibility of a collision, and
that the driver is not facing forward, PCS warnings are given in advance to
warn the driver. If the situation does not improve, pre-collision alert brak-
ing will be applied.
(P. 295)
■ Steering gear control (VGRS) (with driver monitor system)
When the system determines that a collision is unavoidable, the steering
gear ratio is changed to help improve the response to steering input.
■ Pre-collision alert braking (with driver monitor system)
When the system determines that the driver is not facing forward, and that
the possibility of a collision persists, the brakes will be applied briefly to
give the driver a sensory warning and encourage them to take preventive
measures. Pre-collision alert braking can also be disabled using the pre-
collision braking off switch.
