nated or flashing (P.77, 79) and all
of the following conditions are met:
● Engine output restriction control
• The Parking Support Brake is
enabled.
• The vehicle speed is 9 mph (15
km/h) or less.
• Vehicles are approaching from the
right or left at the rear of the vehi-
cle at a traveling speed of less
than approximately 5 mph (8
km/h)
• The shift lever is in R.
• The Parking Support Brake deter-
mines that a stronger than normal
brake operation is necessary to
avoid a collision with an approach-
ing vehicle.
● Brake control
• Engine output restriction control is
operating
• The Parking Support Brake deter-
mines that an emergency brake
operation is necessary to avoid a
collision with an approaching vehi-
cle.
■ The Parking Support Brake
function (rear-crossing vehi-
cles) will stop operating when
The function will stop operating if
any of the following conditions are
met:
● Engine output restriction control
• The Parking Support Brake is dis-
abled.
• The collision becomes avoidable
with normal brake operation.
• A vehicle is no longer approaching
from the right or left at the rear of
the vehicle.
● Brake control

■ Detection area of the Parking
Support Brake function (rear-
crossing vehicles)
The detection area of the Parking
Support Brake function (rear-cross-
ing vehicles) differs from the detec-
tion area of the RCTA function
(P.267). Therefore, even if the
RCTA function detects a vehicle and
provides an alert, the Parking Sup-
port Brake function (rear-crossing
vehicles) may not start operating.
■ Conditions under which the
Parking Support Brake func-
tion (rear-crossing vehicles)
will not detect a vehicle
The Parking Support Brake function
(rear-crossing vehicles) is not

WARNING
● Do not modify, disassemble or
paint the sensors.
● Do not replace a rear radar sen-
sor with a part other than a gen-
uine part.
● Do not damage the rear radar
sensors, and always keep the
radar sensors and their sur-
rounding area on the bumper
clean.
● If the area around a rear radar
sensor is subjected to an
impact, the system may not
operate properly due to a sen-
sor malfunction. Have the vehi-
cle inspected by your Toyota
dealer.
● Observe the rear radar sensor
handling precautions. (P.263)
