Situations when the system may operate even though there is no possi-
bility of a collision
In the following situations, the system may operate even though there is no
possibility of a collision.
● Environmental influence
• The vehicle is driven toward a banner or flag, a low-hanging branch or a
boom barrier (such as those used at railroad crossings, toll gates and
parking lots).
• There is an obstacle on the shoulder of the road (when the veh icle is
driven in a narrow tunnel, on a narrow bridge or on a narrow road)
• The vehicle is being parallel parked
• There is a rut or hole in the surface of the road
• When the vehicle is driven on a metal cover (grating), such as those used
for drainage ditches
• The vehicle is driven on a steep slope
• The sensor is covered by water on a flooded road
● Influence from the weather
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system
returns to normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm
● Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parki ng assist
system of another vehicle, a vehicle detector, a motorcycle eng ine 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
• 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
■ In the unlikely event that the Parking Support Br ake function (for static
objects) mistakenly operates at a crossing or elsewhere
Even in the unlikely event that the Parking Support Brake funct ion (for static
objects) mistakenly operates at a crossing or elsewhere, brake control is can-
celed after approximately 2 seconds, allowing you to proceed fo rward and
leave the area. Furthermore, brake control is also canceled whe n the brake
pedal is depressed. Depressing the accelerator pedal again allows you to
proceed forward and leave the area.
■ Situations in which the syst em may not operate normally
In the following situations, the system may not operate normall y.
● Environmental influence
• There is an obstacle that cannot be detected between the vehic le and
another obstacle that can be detected
• An obstacle such as another vehicle, a motorcycle, a bicycle o r a pedes-
trian cuts in front of the vehicle or jumps out from the side.
● Influence from the weather
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system
returns to normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm • The area around the sensor is extremely hot or cold
• The wind is strong

Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parki ng assist
system of another vehicle, a vehicle detector, a motorcycle eng ine or the
air brake of a large vehicle
• Electronic components (such as a backlit license plate [especi ally fluores-
cent types], fog lights, a fender pole or a wireless antenna) a re installed

• 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
■ 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

WARNING
■For safe use
Do not rely solely upon the system. Relying solely upon the sys tem may
lead to an unexpected accident.
● Driving safely is the sole responsibility of the driver. Pay ca reful attention
to the surrounding conditions in order to ensure safe driving. The Parking
Support Brake function (for static objects) can provide support to lessen
the severity of collisions. However, it may not operate dependi ng on the
situation.
● The Parking Support Brake function (for static objects) is not a system
designed to completely stop the vehicle. Furthermore, even if t he brake
control is able to stop the vehicle, brake control is canceled after approxi-
mately 2 seconds, so depress the brake pedal immediately.
■ In order for the system to operate properly
Make sure to observe the following precautions regarding the se nsors
(  P. 265). Failure to observe these precautions may cause the sen sors
not to operate properly, and may result in an unexpected accide nt.
● Do not perform work such as modification, disassembly or painti ng
● Only perform replacements using genuine parts
● Do not subject the area around the sensors to any impacts
● Do not damage the sensors, and always keep them clean
■ Handling the suspension
Do not modify the suspension, as changes to the height or incli ne of the
vehicle may prevent the sensors from correctly detecting obstac les, may
cause the system not operate, or may cause the system to operate unnec-
essarily.

the sensors. The sensors may not function properly if subjected to steam.
■ Preventing unnecessary operation
In the following situations, turn the Parking Support Brake fun ction (for static
objects) off. The system may operate even though there is no po ssibility of
a collision.
● A chassis roller, chassis dynamo, free roller or similar equipm ent is being
used for an inspection, etc.
● The vehicle is being loaded onto a ship, truck or other transpo rt vessel
● The suspension has been lowered or tires that have a different size than
the genuine tires are equipped
● The height of the vehicle has drastically changed due to the ca rried load

WARNING
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function whi ch alerts the
driver that a vehicle is present in the blind spot. Do not over ly rely on the
Blind Spot Monitor function. The function cannot judge if it is safe to change
lanes, therefore over reliance could cause an accident resultin g in death or
serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.
