■Parking Support Brake function while the Simple Advanced Parkin g
Guidance System is operating
While the Simple Advanced Parking Guidance System is operating, if the sys-
tem detects an obstacle that could result in a collision, hybri d system output
restriction control and brake control of the Parking Support Br ake function are
operated, regardless of whether the Parking Support Brake funct ion is on or
off. ( P. 444)
● After the Parking Support Brake function operates, operation of the Simple
Advanced Parking Guidance System is temporarily stopped, and operation
of the Parking Support Brake function is indicated on the multi -information
display. ( P. 448)

■ Shifting while the Simple Advanced Parking Guidance System is operat-
ing
If the system determines that the drivers intends to move forward or in
reverse, assistance continues even if the drivers shifted before being
prompted to do so by the system. However, because driver operat ion differs
from the guidance provided by the system, the number of turning maneuvers
may increase.
