●Instances of the Blind Spot Monitor unnecessarily detecting a vehicle
and/or object may increase in the fol- lowing situations:• When the sensor is misaligned due to
a strong impact to the sensor or its surrounding area• When the distance between your vehi-
cle and a guardrail, wall, etc., that enters the detection area is short• When driving up and down consecu-
tive steep inclines, such as hills, dips in the road, etc.• When vehicle lanes are narrow, or
when driving on the edge of a lane, and a vehicle traveling in a lane other than the adjacent lanes enters the
detection area • When driving on roads with sharp bends, consecutive curves, or uneven
surfaces • When the tires are slipping or spinning• When the distance between your vehi-
cle and a following vehicle is short • When an accessory (such as a bicycle carrier) is installed to the rear of the

WARNING
■When using the Toyota parking
assist-sensor
Observe the following precautions. Failing to do so may result in the vehi-
cle being unable to be driven safely and possibly cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or reversing, check
the areas surrounding the vehicle (especially the sides of the vehicle) for safety, and drive slowly, using
the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
●The area directly under the bum-pers is not detected.Thin posts or objects lower than the
sensor may not be detected when approached, even if they have been detected before.
■When to disable the function
In the following situations, disable the
function as it may operate even though there is no possibility of a colli-sion.
●The vehicle is equipped with a fender pole, wireless antenna or fog
lights.

4-5. Using the driving support systems
■The system can be operated when
●The engine switch is in ON.
●Toyota parking assist-sensor function
is on.
●The vehicle speed is less than about
10 km/h (6 mph).
●A shift lever other than P is selected.
●Steering wheel is turned approxi- mately 90° or more (Front side sen-
sors, rear side sensors) (if equipped)
■If “Clean Parking Assist Sensor” is displayed on the multi-information display
A sensor may be covered with water drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from
the sensor to return the system to nor- mal.
Also, due to ice forming on a sensor at
low temperatures, a warning message may be displayed or the sensor may not
be able to detect an object. Once the ice melts, the system will return to normal.
■Sensor detection information
The following situations may occur
during use.
●The sensors may be able to only
detect objects near the front and rear bumpers.
●Depending on the shape of the object and other factors, the detection dis-tance may shorten, or detection may
be impossible.
●If an object is extremely close to a
sensor, it may not be detected.
WARNING
●The front or rear bumper or a sen- sor receives a strong impact.
●A non-genuine Toyota suspension (lowered suspension, etc.) is
installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
■When using Toyota parking assist-sensor
In the following situations, the system
may not function correctly due to a sensor malfunction, etc. Have the vehicle checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●The Toyota parking assist-sensor operation display flashes or shows continuously, and a beep sounds
when no objects are detected.
●If the area around a sensor collides
with something, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display flashes or is displayed continuously and a buzzer does not sound, except when the mute func-
tion has been turned on.
●If a display error occurs, first check
the sensor. If the error occurs even when there is no ice, snow or mud on the sen-
sor, it is likely that the sensor is mal- functioning.
■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.

●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.

RCTA (Rear Crossing
Traffic Alert)*
The RCTA function uses the
BSM rear side radar sensors
installed behind the rear
bumper. This function is
intended to assist the driver in
checking areas that are not
easily visible when backing
up.
WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, tak-ing care to observe your surround-
ings.
The RCTA function is only a supple- mentary function which alerts the
driver that a vehicle is approaching from the right or left at the rear of the vehicle. As the RCTA function may
not function correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.
Over reliance on this function may lead to an accident resulting death or serious injury.

PKSB (Parking Support
Brake)*
The Parking Support Brake
system consists of the follow-
ing functions that operate
when driving at a low speed or
backing up, such as when
parking. When the system
determines that a collision
with a detected object is high,
a warning operates to urge the
driver to take evasive action. If
the system determines that the
possibility of a collision with a
detected object is extremely
high, the brakes are automati-
cally applied to help avoid the
collision or help reduce the
impact of the collision.

WARNING
■Limitations of the Parking Sup- port Brake system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi- cle.
Depending on the vehicle and road
conditions, weather, etc., the system may not operate.
The detection capabilities of sensors
and radars are limited. Always drive while checking the safety of the sur-roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur- roundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity of collisions. However, it may not operate in some situations.
●The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the system has stopped the vehicle, it is necessary to depress the brake
pedal immediately as brake control will be canceled after approximately 2 seconds.
NOTICE
■If “PKSB Unavailable” is dis-played on the multi-information
display and the PKSB OFF indi- cator is on
If this message is displayed immedi-
ately after the engine switch is changed to ON, operate the vehicle carefully, paying attention to your sur-
roundings. It may be necessary to drive the vehicle for a certain amount of time before the system returns to
normal. (If the system does not return to normal after driving for a while, clean the sensors and their surround-
ing area on the bumpers.)
