QSensor detection range
The detection range of the Parking Support Brake function differs from the
detection range of the Toyota parking assist-sensor. (P. 455)
Therefore, even if the Toyota parking assist-sensor detects an obstacle and
provides a warning, the Parking Support Brake function may not start operat-
ing.
QSystem operation
When the vehicle is stopped by system operation, the Parking Support Brake
function stops and the PKSB OFF indicator illuminates.
QSystem recovery
When the Parking Support Brake function is stopped by system operation
and you would like to resume operation, either turn the Parking Support
Brake function on again (P. 464), or turn the power switch off and then back
on. Furthermore, when the vehicle moves with an obstacle no longer in the
traveling direction of the vehicle, or when the traveling direction of the vehicle
changes (such as when switching from moving forward to backing up, and
vice versa), system operation automatically resumes.
QObstacles not detected by the sensors
The following obstacles may not be detected by the sensors.
OObjects such as people, cloth and snow, that are difficult for sonic waves to
reflect off of. (In particular, people may also not be detected depending on
the type of clothing they are wearing.)
OObjects not perpendicular with the ground, objects not at a right angle to the
traveling direction of the vehicle, uneven objects or waving objects
OLow objects
OThin objects such as wires, fences, ropes and signposts
OObjects that are extremely close to the bumper
QSituations in which the system may not operate properly
P. 457
QSituations in which the system may operate even if there is no possibil-
ity of a collision
P. 459
QIn the unlikely event that the Parking Support Brake function mistakenly
operates at a crossing or elsewhere
Even in the unlikely event that the Parking Support Brake function mistakenly
operates at a crossing or elsewhere, brake control is canceled after approxi-
mately 2 seconds, allowing you to proceed forward and leave the area. Fur-
thermore, brake control is also canceled when the brake pedal is depressed.
Depressing the accelerator pedal again allows you to proceed forward and
leave the area.

QParallel parking assist mode operating conditions
OIn order to operate the parallel parking assist mode correctly, drive slowly (at
a speed at which the vehicle can be quickly stopped) parallel to the road (or
shoulder) while maintaining a distance of approximately 1 m (3.3ft.) to any
parked vehicles.
OThe function cannot be used when the vehicle speed is approximately
30 km/h (19 mph) or higher.
OThe front side sensors and rear side sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detection is not
possible (P. 507), guidance is not issued.
OIf there are no parked vehicles, the parking spot cannot be determined.
Therefore, the parallel parking assist mode cannot be operated.
OIf unable to detect the environment surrounding the parking space, the par-
allel parking assist mode may not be able to operate.
OGuidance will continue until the vehicle speed meets or exceeds approxi-
mately 30 km/h (19 mph) or the function is turned off using the S-IPA switch.
QTiming for pressing the S-IPA switch
In the following cases, the assist mode may also operate during the steps
taken to park using the parallel parking assist mode. However, in these
cases, conduct parking procedures according to the information on the multi-
information display.
OIn step the S-IPA switch is pressed after already passing over the target
parking spot.
If the vehicle is not stopped in step , pressing the S-IPA switch 1 time
while the vehicle is in motion allows you to select “Parallel Parking” and
proceed directly to step .
OThe vehicle is moved up to the position in step without the S-IPA switch
being pressed. Then the S-IPA switch is pressed after having changed the
shift position to R.

QExit parallel parking assist mode
O During assist control, if the driver determines that they are at a position
where take-off is possible and operates the steering wheel, ass ist control is
stopped at that position.
O Assist control cannot be used if there are no parked vehicles ahead, or if the
gap between the front of your vehicle and the vehicle parked ah ead is too
large.
O When using the exit parallel parking assist mode, the assist mode may not
be able to operate depending on the surrounding environment.
NOTICE
O The detection range of the sensors (P. 455) is limited. Directly confirm
the safety of your surroundings, and if there is a possibility of a contact
accident, stop the vehicle by depressing the brake pedal.

the vehicle can be quickly stopped).
O In order to operate the function correctly, drive slowly (at a speed at which
the vehicle can be quickly stopped). Come to a full stop so tha t the center of
the parking space is nearly perpendicular to the vehicle, and t hen operate
the S-IPA switch.
O The function cannot be used when the vehicle speed is approximately
30 km/h (19 mph) or higher.
O The front side sensors and rear side sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detect ion is not
possible ( P. 507), guidance is not issued.
O If there are no parked vehicles, the parking spot cannot be determined.
Therefore, the back-in parking assist mode cannot be operated.
O If unable to detect the environment surrounding the parking space, the
back-in parking assist mode may not be able to operate.
O Depending on the condition of the park-
ing space, if there is not enough space

QTips for using the back-in parking assist mode
O Leave a gap of approximately 1 m
(3.3 ft.) from any parked vehicles and
approach the target parking spot. If the
gap between your vehicle and any
parked vehicles is too large, the front
side sensors and rear side sensors may
not be able to detect the parked vehi-
cles.
O Stop so that the center of the target
parking spot is perpendicular to the vehi-
cle. Furthermore, only push the S-IPA
switch when the vehicle is at a complete
stop.
NOTICE
O If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an an gle or may
deviate from the parking spot. In these cases, do not use the b ack-in park-
ing assist mode.
O When parking in a narrow space, the vehicle will come close to adjacent
vehicles. If it seems the vehicle may make contact, stop the ve hicle by
depressing the brake pedal.
O It may not be possible to detect objects that are low to the ground. Directly
confirm the safety of your surroundings and, if it seems the ve hicle may
make contact with an obstacle, stop the vehicle by depressing t he brake
pedal.
O Depending on the surrounding environment, such as other parked vehi-
cles, the vehicle may be parked at an angle or may deviate from the park-
ing spot. Manually adjust vehi cle alignment as necessary.

may not operate properly. When replacing tires, contact any aut horized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
O The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on o ne side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle posit ion greatly
differ, have the vehicle inspected by any authorized Toyota ret ailer or
Toyota authorized repairer, or any reliable repairer.
O Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when depar ting from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use t his function
when departing from a parallel parking spot. In the event that the steering
control operates, either turn the system off using the S-IPA sw itch or oper-
ate the steering wheel to stop the control.
O If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.

WARNING
OObserve the following precautions, as the sensors may stop functioning
properly which may lead to an accident.
• Do not subject the sensor to strong shocks by hitting it, etc. The sen-
sors may not function properly.
• When using a high-pressure washer to wash the vehicle, do not spray
water directly on the sensors. Equipment may not function prope rly if
subjected to an impact from strong water pressure. If the vehic le
bumper strikes something, equipm ent may not operate properly due to
a sensor malfunction. Have the vehicle inspected at any authori zed
Toyota retailer or Toyota author ized repairer, or any reliable repairer.
O In the following situations, the sensors may not operate normally and may
lead to an accident. Drive carefully.
• Obstacles cannot be detected in the side areas until 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.
• The sensor is frozen (if it thaws, the system returns to norma l).
A warning message may display at particularly low temperatures due to
the sensor freezing and it may not detect parked vehicles.
• The sensor is blocked by someone’s hand.
• The vehicle is tilted a large amount.
• The temperature is extremely hot or cold.
• The vehicle is driven on undulating roads, slopes, gravel road s, in areas
with tall grass, etc.
• An ultrasonic wave source is nearby, such as the horn or senso rs of
another vehicle, a motorcycle engine or the air brake of a larg e vehicle.
• Heavy rain or a water strikes the vehicle.
• The angle of the sensor may be deviated when assist control st arts
even if there is a parked vehicle in the target parking spot. H ave the
vehicle inspected at any authorized Toyota retailer or Toyota a uthorized
repairer, or any reliable repairer.
• Do not install any accessories within the sensor detection ran ge.
