Q 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 driver
to take evasive action.
Q 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.
Q 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.
Q Emergency steering assist (for
region A)
If the system determines that the possi-
bility of a frontal collision is high and
that there is sufficient space for the
vehicle to be steered into within its
lane, and the driver has begun evasive
maneuver or steering, emergency
steering assist will assist the steering
movements to help enhance the vehi-
cle stability and for lane departure pre-
vention. During operation, the
indicator will illuminate in green.
Q Intersection right/left turn assis-
tance (for region A)
If the system determines that there is a
high possibility of a collision in the fol-
lowing situations, it will assist with Pre-
collision warning and, if necessary Pre-
collision braking.
Depending on the configuration of the
intersection, it may not be possible to
support.
