■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 vehicle 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 parking assist-
sensor of another vehicle, a vehicle detector, a motorcycle engine 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
• The vehicle is driven on a narrow
road
• The vehicle is driven on a gravel road
or in an area with tall grass

PRIUS PHV_OM_OM47A89E_(EE)
● Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the carried 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 Intelligent Clearance Sonar function mistak-
enly operates at a crossing or elsewhere
Even in the unlikely event that the Intelligent Clearance Sonar function mis-
takenly operates at a crossing or elsewhere, brake control is canceled after
approximately 2 seconds, allowing you to proceed forward and leave the
area. Furthermore, 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.
■ Situations in which the system may not operate normally
In the following situations, the system may not operate normally.
● Environmental influence
• There is an obstacle that cannot be detected between the vehicle and
another obstacle that can be detected
• An obstacle such as another vehicle, a motorcycle, a bicycle or 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

■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 “ICS Unavailable” is displayed on the multi-information display
and the ICS 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 dealer or repairer, or another duly qualified and
equipped professional.
●System initialization may not have been performed after removal and instal-
lation of the 12-volt battery. Perform system initialization.
■When “ICS Malfunction Visit Your Dealer” is displayed on the multi-infor-
mation display, the ICS OFF indicator flashes and the buzzer sounds
The system may not be operating properly. Have the vehicle inspected at any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional.

WARNING
■For safe use
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 Intelli-
gent Clearance Sonar function can provide support to lessen the severity
of collisions. However, it may not operate depending on the situation.
● The Intelligent Clearance Sonar function is not a system designed to com-
pletely stop the vehicle. Furthermore, even if the Intelligent Clearance
Sonar function is able to stop the vehicle, brake control is canceled after
approximately 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 sensors
( P. 445). Failure to observe these precautions may cause the sensors
not to operate properly, and may result in an unexpected accident.
● Do not perform work such as modification, disassembly or painting
● 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 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.

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 dealer or repairer, or another duly qualified and
equipped professional.
● 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 Intelligent Clearance Sonar 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

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 Intelligent Clearance Sonar 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 Intelligent
Clearance Sonar function is on or off. ( P. 458)

■Intelligent Clearance Sonar 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 Intelligent Clearance Sonar func-
tion are operated, regardless of whether the Intelligent Clearance Sonar func-
tion is on or off. (P. 445)
●After the Intelligent Clearance Sonar function operates, operation of the
Simple Intelligent Parking Assist System is temporarily stopped, and opera-
tion of the Intelligent Clearance Sonar function is indicated on the multi-
information display. (P. 449)
●When operation of the Simple Intelligent Parking Assist System is stopped 3
times by operation of the Intelligent Clearance Sonar function, the Simple
Intelligent Parking Assist System is canceled.
●Once the Simple Intelligent Parking Assist System becomes available after
the Intelligent Clearance Sonar 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 accord-
ing to the prompt on the multi-information display and pressing the S-IPA
switch (P. 459) again.
■Shifting while the Simple Intelligent Parking Assist System is operating
If the system determines that the drivers intends to move forward or in
reverse, assistance continues even if the drivers 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. the obstacle detection range) can be changed. (Customizable
features: P. 708)
