■Obstacle warning function
When an obstacle in the side areas is within the vehicle course while the
vehicle is moving forward or backward, this function inform the driver by the
display and the buzzer.
■ Obstacle detection in side areas
●Obstacles in the side areas are detected while driving by scann ing the side
areas with the side sensors. Recognized obstacles are retained in memory
for up to approximately 2 minutes.
● Obstacles may not be detected in the side areas until the scan completes.
After the power switch is turned on, scanning completes after driving the
vehicle for a short period of time.
● When an obstacle such as another vehicle, pedestrian or animal is detected
by the side sensors, the obstacle may continue to be detected e ven after it
has left the side sensor detection area.
■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an obstacle may not be detected. If the sens or thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ Customization
Settings (e.g. buzzer volume) can be changed.

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 w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen, the screen m ay 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, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing 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 in stalled.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and c ondition of

WARNING
■Side sensors
In the following situations, the intuitive parking assist may n ot operate nor-
mally and may result in an unexpected accident. Drive carefully .
● Obstacles may not be detected in the side areas until the vehic le is driven
for a short time and a scan of the side areas is completed. ( P. 368)
● Even after the scan of the side areas is completed, obstacles s uch 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. 363) 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 d irection 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 intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction etc. Have the vehicle checked by your Toyota dealer.
● Intuitive parking assist 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 t he 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 c lose to
the sensors. The sensors may not function properly if subjected to steam.

●Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parki ng assist
sensors of another vehicle, a vehicle detector, a motorcycle en gine 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 c arried load
(the nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact
■ Parking Support Brake function while the Simple Advanced Parkin g
Guidance System is operating
P. 388
■ When removing and instal ling the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight a head for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or hi gher.
■ 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 du e 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 i nspected at
your Toyota dealer.
● 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 m ulti-
information display, the PKSB OFF indicator flashes and the buz zer
sounds
The system may not be operating properly. Have the vehicle inspected at
your Toyota dealer.

■Parking Support Brake function while the Simple Advanced Parkin g
Guidance System is operating
While the Simple Advanced Parking Guidance System is operating, if the sys-
tem detects an obstacle that could result in a collision, hybri d system output
restriction control and brake control of the Parking Support Br ake function are
operated, regardless of whether the Parking Support Brake funct ion is on or
off. ( P. 375)
● After the Parking Support Brake function operates, operation of the Simple
Advanced Parking Guidance System is temporarily stopped, and operation
of the Parking Support Brake function is indicated on the multi -information
display. ( P. 379)
● When operation of the Simple Advanced Parking Guidance System i s
stopped 3 times by operation of the Parking Support Brake funct ion, the
Simple Advanced Parking Guidance System is canceled.
● Once the Simple Advanced Parking Guidance System becomes availa ble
after the Parking Support Brake function is operated, a message prompting
you to shift is displayed on the multi-information display. Ope ration of the
Simple Advanced Parking Guidance System can be resumed by shift ing
according to the prompt on the multi-information display and pr essing the
S-APGS switch ( P. 389) again.
■ Shifting while the Simple Advanced Parking Guidance System is operat-
ing
If the system determines that the driver intends to move forwar d 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 inc rease.
■ Customization
Settings (e.g. obstacle detection range) can be changed. (Custo mizable fea-
tures: P. 690)
