WARNING
■Handling the rear side radar sen-
sor
Blind Spot Monitor sensors are installed behind the left and right
sides of the rear bumper respectively. Observe the following to ensure the Blind Spot Monitor can operate cor-
rectly.
●Keep the sensors and the sur- rounding areas on the rear bumper clean at all times.
If a sensor or its surrounding area on
the rear bumper is dirty or covered
with snow, the Blind Spot Monitor may
not operate and a warning message
( →P.237) will be displayed. In this sit-
uation, clear off the dirt or snow and
drive the vehicle with the operation
conditions of the BSM function
( →P.241) satisfied for approximately
10 minutes. If the warning message
does not disappear, have the vehicle

●There will be a short delay between
object detection and display. Even at low speeds, there is a possibility that the object will come within the sen-
sor’s detection areas before the dis- play is shown and the warning beep sounds.
●It might be difficult to hear the buzzer due to the volume of the audio system
or air flow noise of the air conditioning system.
●It may be difficult to hear the buzzer if buzzers for other systems are sound-ing.
■Conditions under which the func-
tion may not function correctly
Certain vehicle conditions and the sur- rounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this may occur are listed below.
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
●A sensor is frozen. (Thawing the area
will resolve this problem.) In especially cold weather, if a sensor is frozen the sensor display may be
displayed abnormally, or objects, such as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●The vicinity of the vehicle is noisy due
to vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic
waves.
●There is another vehicle equipped
with parking assist sensors in the vicinity.
●A sensor is coated with a sheet of spray or heavy rain.
●If a sensor is hit by a large amount of water, such as when driving on a
flooded road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly detected
The shape of the object may prevent the
sensor from detecting it. Pay particular attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro- jecting outwards in the direction of your vehicle
People may not be detected if they are wearing certain types of clothing.

■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the PKSB OFF indicator is not illuminated or
flashing ( →P.83, 84) and all of the fol- lowing conditions are met:
●Engine output restriction control• The Parking Support Brake is enabled.
• The vehicle speed is 15 km/h (9 mph) or less.
WARNING
●Do not replace a sensor with a part other than a genuine part.
●Do not subject a sensor or its sur-rounding area to a strong impact.
●Do not damage the sensors, and always keep them clean.
●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 vehi-cle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■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 unnecessarily.
■If the Parking Support Brake
function (static objects) oper- ates unnecessarily, such as at a railroad crossing
In the event that the Parking Support Brake function (static objects) oper-ates unnecessarily, such as at a rail-
road crossing, brake control will be canceled after approximately 2 sec-onds, allowing you to proceed forward
and leave the area, brake control can also be canceled by depressing the brake pedal. Depressing the acceler-
ator pedal after brake control is can- celed will allow you to proceed forward 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 malfunctioning.
●When using a high pressure washer to wash the vehicle, do not spray the sensors directly, as doing
so may cause a sensor to malfunc- tion.
●When using steam to clean the vehicle, do not direct steam too close to the sensors as doing so
may cause a sensor to malfunction.
■When to disable the Parking Sup-
port 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
●When loading the vehicle onto a boat, truck or other transport vessel
●If the suspension has been modi-fied or tires of a size other than
specified are installed
●If the front of the vehicle is raised or
lowered due to the carried load
