■ 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.

WARNING
■When to disable the Parking Support Brake
In the following situations, disable the Parking Support Brake as the system
may operate even though there is no possibility of a collision.
● When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
● When loading the vehicle onto a boat, truck or other transport vessel
● If the suspension has been modified or tires of a size other than specified
are installed
● If the front of the vehicle is raised or lowered due to the carried load
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional tr im strip, etc.), bicycle carrier, or
snow plow
● When using automatic car washing devices
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When tire chains, compact spare tire or an emergency tire puncture repair
kit are used
■ To ensure the system can operate properly
 P. 3 9 2
■ Handling the suspension
Do not modify the suspension, as changes to the height or incline of the
vehicle may prevent the sensors from correctly detecting obstacles, may
cause the system not operate, or may cause the system to operate unnec-
essarily.
■ If the Parking Support Brake function (static objects) operates unnec-
essarily, such as at a railroad crossing
 P. 4 0 1
■ Notes when washing the vehicle

NOTICE
■Preventing sensor malfunctions
● If the area around a sensor is subjected to an impact, equipment may not
operate properly due to a sensor malfunction. Have the vehicle inspected
at any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
● When using a high-pressure washer to wash the vehicle, do not spray
water directly on the sensors. The sensors may not function properly if
subjected to an impact from strong water pressure.
● 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.
■ Preventing unnecessary operation
In the following situations, turn the Parking Support Brake function off. The
system may operate even though there is no possibility of a collision.
● A chassis roller, chassis dynamo, free roller or similar equipment is being
used for an inspection, etc.
● The vehicle is being loaded onto a ship, truck or other transport 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 carried load
(the nose tilts up or down).
● A towing eyelet is installed
● When using an automatic car wash

S-IPA (Simple Intelligent Parking Assist
System)
■Function summary
The Simple Intelligent Parking Assist System automatically oper-
ates the steering wheel to provide support when backing into an
area near a target parking spot, and when departing from a parallel
parking spot. (Changing the shift position and speed adjustment
when moving forward or backing up are not performed automati-
cally.)
● The Simple Intelligent Parking Assist System does not park the
vehicle automatically. It is a system that provides support when
pulling out of a perpendicular or parallel parking spot.
● The Simple Intelligent Parking Assist System provides steering
wheel operation assistance to guide the vehicle toward the
selected intended parking spot. The selected intended parking
spot may not always be reachable, depending on road and vehi-
cle conditions at the time of parking, and the distance to the
intended parking spot.
■Linking with the Parking Support Brake function
While the Simple Intelligent Parking Assist System is operating, if
the system detects an obstacle that could result in a collision, the
emergency brakes operate, regardless of whether the Parking Sup-
port Brake function is on or off. ( P. 407)
: If equipped
Simple Intelligent Parking Assist System
WARNING
●When backing up or proceeding forward, be sure to directly confirm the
safety of the area to the front or rear, and the area around the vehicle, and
slowly back up or proceed forward while adjusting the vehicle speed by
depressing the brake pedal.
● If it seems the vehicle may make contact with a pedestrian, another vehi-
cle or any other obstacles, stop the vehicle by depressing the brake pedal,
and then press the S-IPA switch ( P. 408) to turn the system off.

■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. 396)
●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. 400)
●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. 408) 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. 670)
