tions are met:
O Engine output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is approximately 15
km/h (9 mph) or less.
• There is a static object in the traveling
direction of the vehicle and approxi-
mately 2 to 4 m (6 to 13 ft.) away.

that a stronger-than-normal brake oper-
ation is necessary to avoid a collision.

ating
• The Parking Support Brake determines

The function will stop operating if any of the
following conditions are met:
O Engine output restriction control
• The Parking Support Brake is disabled.
• The system determines that the collision
has become avoidable with normal brake
operation.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from the
vehicle or in the traveling direction of the
vehicle.
O 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.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from the

Q Detection range of the Parking Support
Brake function (Static Objects Front
and Rear of the Vehicle)

Brake function (Static Objects Front and
Rear of the Vehicle) differs from the detec-
tion range of the Lexus parking assist-sen-
sor. (oP.323) Therefore, even if the Lexus
parking assist-sensor detects an object and
provides a warning, the Parking Support
Brake function (Static Objects Front and
Rear of the Vehicle) may not start operat-
ing.
