■Situations in which the Intelligent Clearance Sonar function may operate
even if there is no possibility of a collision
In some situations such as the following, the Intelligent Clearance Sonar
function may operate even though there is no possibility of a collision.
●Vehicle surroundings
• When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots).
• When driving on a narrow path surrounded by a structure, such as in a
tunnel or on an iron bridge
• When parallel parking
• When there is a rut or hole in the surface of the road
• When driving on a metal cover (grating), such as those used for drainage
ditches
• When driving on a steep slope
• If a sensor is hit by a large amount of water, such as when driving on a
flooded road
●Weather
• If a sensor is covered with ice, snow, dirt, etc. (when cleared, the system
will return to normal)
• If heavy rain or water strikes a sensor
• When driving in inclement weather such as fog, snow or a sandstorm
●Other ultrasonic waves sources
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices
which produce ultrasonic waves are near the vehicle
• If a sticker or an electronic component, such as a backlit license plate
(especially fluorescent type), fog lights, a fender pole or wireless antenna
is installed near a sensor • When driving on a narrow road

NOTICE
■To prevent the system from malfunctioning
●If the area around a sensor is subjected to an impact, the system may not
operate properly due to the sensor being misaligned. Have the vehicle
inspected by your Toyota dealer.
●When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction.
●When using steam to clean the vehicle, do not direct steam too close to

■To prevent a radar sensor from malfunctioning
●If the area around a radar sensor is subjected to an impact, the system
may not operate properly due to a sensor malfunction. Have the vehicle
inspected by your Toyota dealer.
●Observe the radar sensor handling precautions. (P. 279)
■To prevent unnecessary operation of the Intelligent Clearance Sonar
system
In the following situations, disable the Intelligent Clearance Sonar system
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 trim strip, etc.), bicycle carrier, or
snow plow
●When using an automatic car wash

■Situations in which the system may operate even though there is no
possibility of a collision
In some situations such as the following, the Rear Cross Traffic Auto Brake
function may operate even though there is no possibility of a collision.
●When there are spinning objects near your vehicle such as the fan of an air
conditioning unit
●When water is splashed or sprayed toward the rear bumper, such as from a
sprinkler ●When the parking space faces a street
and vehicles are being driven on the
street
●When a detected vehicle turns while
approaching the vehicle
●When a vehicle passes by the side of
your vehicle
●When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may
reflect electrical waves toward the rear
of the vehicle, is short

■Situations in which the Rear Cross Traffic Auto Brake function may not
operate properly
In some situations such as the following, this function may not operate prop-
erly.
●Objects and vehicles which the radar sensors are not designed to detect
• Stationary objects
• Vehicles which are moving away from your vehicle
• Pedestrians, motorcycles, bicycles, etc.
*
• Objects which are extremely close to a radar sensor
• Vehicles which are approaching from the right or left at the rear of the
vehicle at a traveling speed of less than approximately 5 mph (8 km/h)
• Vehicles which are approaching from the right or left at the rear of the
vehicle at a traveling speed of more than approximately 15 mph (24 km/h)
*: Depending on conditions, detection of a vehicle and/or object may occur.
●Situations in which the radar sensors may not be able to detect an object
• When a sensor or the area around a sensor is extremely hot or cold
• If the rear bumper is covered with ice, snow, dirt, etc.
• If heavy rain or water strikes the vehicle
• When the detection area of a radar sensor is obstructed by an adjacent
vehicle
• If the vehicle is significantly tilted
• When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or
snow plow
• 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
• If a sticker or an electronic component, such as a backlit license plate
(especially fluorescent type), fog lights, a fender pole or wireless antenna
is installed near a radar sensor
• If the orientation of a radar sensor has been changed due to a collision or
other impact or removal and installation
• When multiple vehicles are approaching with only a small gap between
each vehicle
• When a vehicle is approaching at high speed

■Conditions in which the wireless charger may not operate correctly
In the following situations, the wireless charger may not operate correctly:
●When a portable device is fully charged
●When there is a foreign object between the charging area and portable
device
●When a portable device becomes hot while charging
●When a portable device is placed on the wireless area with its charging
surface facing up
●When a portable device is not centered on the charging area
●When the vehicle is near a TV tower, electric power plant, gas station,
radio station, large display, airport or other facility that generates strong
radio waves or electrical noise
●When the portable device is in contact with, or is covered by any of the fol-
lowing metallic objects:
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Metal hand warmers
• Media such as CDs and DVDs
●When wireless keys (that emit radio waves) other than those of your vehi-
cle are being used nearby.
If in situations other than above the wireless charger does not operate prop-
erly or the operation indicator light is blinking, the wireless charger may be
malfunctioning. Contact your Toyota dealer.
■To prevent failure or damage to data
●Do not bring magnetic cards, such as a credit card, or magnetic recording
media, close to the wireless charger while charging. Otherwise, data may
be erased due to the influence of magnetism.
Additionally, do not bring precision instruments such as wrist watches,
close to the wireless charger, as such objects may malfunction.
●Do not leave portable devices in the cabin. The temperature inside the
cabin may become high when parked in the sun, and cause damage to the
device.
■To prevent 12-volt battery discharge
Do not use the wireless charger for a long period of time with the hybrid sys-
tem stopped.
