surrounding brightness changes sud-
denly, such as at the  entrance or exit of a 
garage or underground parking lot
• When backing up in a dim environment  such as during dusk or in an underground 
parking lot
●Even though there are no pedestrians in 
the detection area, some  objects, such as 
the following, may be detected, possibly 
causing the rear camera detection func-
tion to operate.
• Three dimensional objects, such as a  pole, traffic cone, fence, or parked vehi-
cle
• Moving objects, such as a car or motor- cycle
• Objects moving toward your vehicle 
when backing up, such as flags or pud-
dles (or airborne matter, such as smoke, 
steam, rain, or snow)

■The Parking Support Brake function 
(static object) will operate when
The function will operate when the PKSB 
OFF indicator is not illuminated or flashing 
(  P.66, 67) and all of the following condi-
tions are met:
●Hybrid system output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is 9 mph (15 km/h) or  less.
• There is a static object in the traveling  direction of the vehicle and 6 to 13 ft. (2 
to 4 m) away.
• The Parking Support Brake determines  that a stronger-than-normal brake opera-
tion is necessary to avoid a collision.
●Brake control
• Hybrid system output restriction control  is operating.
• The Parking Support Brake determines 
that an immediate brake operation is nec-
essary to avoid a collision.

WARNING
●If the area around a radar sensor is 
subjected to an impact, the system 
may not operate properly due to a 
sensor malfunction. Have the vehicle 
inspected by your  Lexus dealer.
■Handling the suspension
Do not modify the suspension, as 
changes to the height or inclination of the 
vehicle may prevent the sensors from 
detecting objects correctly or cause the 
system to not operate or operate unnec-
essarily.
■If the Parking Support Brake function 
(static objects) operates unnecessar-
ily, such as at a railroad crossing
In the event that the Parking Support 
Brake function (static objects) operates 
unnecessarily, such as at a railroad cross-
ing, brake control w ill be canceled after 
approximately 2 seconds, allowing you 
to proceed forward and leave the area, 
brake control can also be canceled by 
depressing the brake pedal. Depressing 
the accelerator pedal after brake control 
is canceled will allow you to proceed for-
ward and leave the area.
■Notes when washing the vehicle
Do not apply intensive bursts of water or 
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.
●When using a high pressure washer to 
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a 
sensor to malfunction.
●When using steam to clean the vehicle, 
do not direct steam too close to the 
sensors as doing so may cause a sen-
sor to malfunction.
■When to disable the Parking Support 
Brake
In the following situations, disable the 
Parking Support Brake as the system 
may operate even though there is no 
possibility of a collision.
●When inspecting the vehicle using a 
chassis roller, chassis dynamo or free 
roller
