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. 456)
● 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. 451) temporary turn
off.
■ 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.
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.

■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.
■ 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.
WARNING
■ Cautions regarding the use of the system
Do not rely solely upon the system. Relying solely upon the system may
lead to an unexpected accident.
● Driving safely is the sole responsibility of the driver. Pay careful attention
to the surrounding conditions in order to ensure safe driving. The Parking
Support Brake function can provide suppor t to lessen the severity of colli-
sions. However, it may not operate depending on the situation.
● The Parking Support Brake function is not a system designed to com-
pletely stop the vehicle. Furthermore, even if the Parking Support Brake
function is able to stop the vehicle, brake control is canceled after approxi-
mately 2 seconds, so depress the brake pedal immediately.
● It is extremely dangerous to check the system operations by intentionally
driving the vehicle into the direction of a wall, etc. Never attempt such
actions.

■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. 464)
●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. 468)
●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. 476) 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. 726)

■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. 477)
*: The back-in parking assist mode can be switched to when its operating
conditions are met ( P. 496). When the operating conditions are not met,
it switches to off.

■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist control starting position, and then the parallel
parking assist mode can be used. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assist
control is also provided if necessary.
Continue moving forward
with the vehicle parallel to
the curb or road, and stop so
that the center of the target
parking spot appears nearly
perpendicular to the vehicle.
Then press the S-IPA switch
1 time to select the parallel
parking assist mode.
Travel straight ahead paral-
lel with the road or curb so
that the parking space is
detected.
A sound is issued and a display is shown to notify you when the
vehicle reaches a position where assist control can be used to
begin backing up from, and then when the shift position is
changed according to guidance provided by the system, steering
wheel auto operation begins.
If the detected parking space or road width (distance to the side of the
road across from the parking space) is narrow, or if there are obstacles
in front of the vehicle, guidance will not be issued.
Parking is complete
This completes the assist mode. Depending on the condition of the
parking space, guidance to starting points for moving forward and back-
ing up, as well as the steering wheel auto operation, are repeated any
time multi-turn maneuvering is necessary following step from the
time the vehicle begins backing up until parking completes.
