LS500h_OM_OM50F42U_(U)
■ The Parking Support Brake function
(rear-crossing vehicles) will operate
when
The function will operate when the PKSB
OFF indicator is not illuminated or flashing
(→P.73, 74) and all of the following condi-
tions are met:
● Hybrid system output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is 10 mph (15 km/h) or
less.
• 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)
• The shift position is in R.
• The Parking Support Brake determines
that a stronger than normal brake opera-
tion is necessary to avoid a collision with
an approaching vehicle.
● Brake control
• Hybrid system output restriction control
is operating.
• 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 operat-
ing when
The function will stop operating if any of the
following conditions are met:
● Hybrid system 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.
■ 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.275). 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
● Observe the rear radar sensor han-
dling precautions. (→P.281)
