an approaching vehicle.
● Brake control
• Engine output restriction control is oper-
ating
• The Parking Support Brake determines
that an emergency brake operation is
necessary to avoid a collision with an
approaching vehicle.
■ The Parking Support Brake function
(rear-crossing vehicles) will stop oper-
ating when
The function will stop operating if any of the
following conditions are met:
● Engine output restriction control
• The Parking Support Brake is disabled.
• 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
• The Parking Support Brake is disabled.
• Approximately 2 seconds have elapsed
since the vehicle was stopped by brake
control.
• The brake pedal is depressed after the
vehicle is stopped by brake control.
• A vehicle is no longer approaching from
the right or left at the rear of the vehicle.
■ Re-enabling the Parking Support Brake
function (rear-crossing vehicles)
P.236
■ Detection area of the Parking Support
Brake function (rear-crossing vehicles)
The detection area of the Parking Support
Brake function (rear-crossing vehicles) dif-
fers from the detection area of the RCTA
function (P.230). Therefore, even if the
RCTA function detects a vehicle and pro-
vides an alert, the Parking Support Brake
function (rear-crossing vehicles) may not
start operating.
■ Conditions under which the Parking
Support Brake function (rear-crossing
vehicles) will not detect a vehicle
The Parking Support Brake function (rear-
crossing vehicles) is not designed to detect
the following types of vehicles and/or
objects:
● Vehicles approaching from directly
behind
● Vehicles backing up in a parking space
next to your vehicle
● Vehicles that the sensors cannot detect
due to obstructions
● Vehicles which suddenly accelerate or
decelerate near your vehicle
● Guardrails, walls, signs, parked vehicles
and similar stationary objects
*
● Small motorcycles, bicycles, pedestrians,
etc.
*
● Vehicles moving away from your vehicle
● Vehicles approaching from the parking
spaces next to your vehicle
*
● Objects which are extremely close to a
radar sensor
*
● Vehicles which are approaching from the
right or left at the rear of the vehicle at a
traveling speed of less than approxi-
mately 5 mph (8 km/h)
● Vehicles which are approaching from the
right or left at the rear of the vehicle at a
traveling speed of more than approxi-
mately 15 mph (24 km/h)
*
: Depending on the conditions, detection
of a vehicle and/or object may occur.
■ RCTA buzzer
Regardless of whether the RCTA function
is enabled or not (P.228), if the Parking
Support Brake function is enabled
(P.233) and brake control is performed,
a buzzer will sound to notify the driver.
■ Situations in which the system may
operate even though there is no possi-
bility of a collision
In some situations such as the following, the
Parking Support Brake function (rear-
