WARNING
■ Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen, the screen may show an
abnormal display, or obstacles may not be detected.
● The sensor is covered in any way.
● In harsh sunlight or intense cold weather
● 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 ultra-
sonic waves.
● The sensor is splashed with water or drenched with heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is leaning considerably to one side.
● The vehicle is equipped with a fender pole or wireless antenna.
● The vehicle is approaching a tall or curved curb.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● The bumper or sensor receives a strong impact.
● A non-genuine Toyota suspension (lowered suspension etc.) is installed.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and condition of
obstacles, detection may not be possible, or the detection range may be
shortened.

WARNING
■Side sensors
In the following situations, the Toyota parking assist-sensor may not operate
normally and may result in an unexpected accident. Drive carefully.
● Obstacles may not be detected in the side areas until the vehicle is driven
for a short time and a scan of the side areas is completed. ( P. 505)
● Even after the scan of the side areas is completed, obstacles such as
other vehicles, people or animals that approach from the sides cannot be
detected.
● Even after the scan of the side areas is completed, obstacles may not be
detected depending on the surrounding situation of the vehicle.
At that time, the side sensor operation displays ( P. 500) temporary turn
off.
■ Obstacles which may not be properly detected
The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low obstacles
● Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
● People may not be detected if they are wearing certain types of clothing.
● Moving objects such as people or animals

NOTICE
■ 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.
● Toyota parking assist-sensor operation display flashes, and a beep
sounds when no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows up and remains on without a beep.
● If a display error occurs, first check the sensor.
If the error occurs even when there is no ice, snow or mud on the sensor, it
is likely that the sensor is malfunctioning.
■ 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 steam to wash the vehicle, do not direct steam too close to
the sensors. The sensors may not function properly if subjected to steam.

When the hybrid system output restriction control or brake control
operates, the buzzer sounds and a message is displayed on the multi-
information display to alert the driver.
Depending on the situation, output restriction control operates to either
limit acceleration or restrict output as much as possible.

●Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parking assist-
sensors of another vehicle, a vehicle detector, a motorcycle engine or the
air brake of a large vehicle
• Electronic components (such as a backlit license plate (especially fluo-
rescent types), fog lights, a fender pole or a wireless antenna) are
installed near the sensors
●Changes in the vehicle
• When driving with the shift position in N
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the carried load
(the nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact

Assist System is operating
P. 525
■When removing and installing the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight ahead for 5 sec-
onds or more at a speed of approximately 35 km/h (22 mph) or higher.
■When “PKSB Unavailable” is displayed on the multi-information display
and the PKSB OFF indicator flashes
●Ice, snow, dirt, etc., may have adhered to the sensor. If this occurs, remove
the ice, snow, dirt, etc., from the sensor to return the system to normal.
Also, a warning message may be displayed at low temperatures due to ice
forming on the sensor, and the sensor may not detect obstacles. Once the
ice melts, the system will return to normal.
●If this message is shown even after removing dirt from the sensor, or shown
when the sensor was not dirty to begin with, have the vehicle inspected at
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
●System initialization may not have been performed after removal and instal-
lation of the 12-volt battery. Perform system initialization.
■When “PKSB Malfunction Visit Your Dealer” is displayed on the multi-
information display, the PKSB OFF indicator flashes and the buzzer
sounds
The system may not be operating properly. Have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.

■Parking Support Brake function while the Simple Intelligent Parking
Assist System is operating
While the Simple Intelligent Parking Assist System is operating, if the system
detects an obstacle that could result in a collision, hybrid system output
restriction control and brake control of the Parking Support Brake function are
operated, regardless of whether the Parking Support Brake function is on or
off. (P. 512)
●After the Parking Support Brake function operates, operation of the Simple
Intelligent Parking Assist System is temporarily stopped, and operation of
the Parking Support Brake function is indicated on the multi-information dis-
play. (P. 516)
●When operation of the Simple Intelligent Parking Assist System is stopped 3
times by operation of the Parking Support Brake function, the Simple Intelli-
gent Parking Assist System is canceled.
●Once the Simple Intelligent Parking Assist System becomes available after
the Parking Support Brake function is operated, a message prompting you
to shift is displayed on the multi-information display. Operation of the Simple
Intelligent Parking Assist System can be resumed by shifting according to
the prompt on the multi-information display and pressing the S-IPA switch
(P. 526) again.
■Shifting while the Simple Intelligent Parking Assist System is operating
If the system determines that the driver intends to move forward or in reverse,
assistance continues even if the driver shifted before being prompted to do so
by the system. However, because driver operation differs from the guidance
provided by the system, the number of turning maneuvers may increase.
■Customization
Settings (e.g. obstacle detection range) can be changed. (Customizable fea-
tures: P. 782)

■Switching using the S-IPA switch
Press the switch
This allows you to switch func-
tions and cancel or restart assist
modes.
While the power switch is on, the vehicle speed is approximately
30 km/h (19 mph) or less, each time the S-IPA switch is pressed the
function switches as follows.
The selected function is indicated on the operation display area of the
multi-information display. ( P. 527)
*: The back-in parking assist mode can be switched to when its operating
conditions are met ( P. 546). When the operating conditions are not met,
it switches to off.
