■Parking Support Brake
function (static objects) (if
equipped)
Ultrasonic sensors are used to
detect static objects, such as a
wall, in the detection area when
driving at a low speed or back-
ing up. ( P.264)
■Parking Support Brake
function (rear-crossing
vehicles) (if equipped)

( P.267)PKSB (Parking Sup-
por t Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
