Conditions under which the vehic le-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake peda l (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
● While the vehicle speed is decreasing to the set speed after th e vehicle
accelerates by depressing the accelerator pedal
●
When the road curves or when the lanes
are narrow
● When steering wheel operation or your
position in the lane is unstable

Turns the intuitive parking
assist on/off
When on, the indicator light
comes on to inform the driver
that the system is operational.
: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via t he multi-information display
and a buzzer. Always check the surrounding area when using
this system.

The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■The system can be operated when
●The engine switch is in ON mode.
● Intuitive parking assist function is on.
● The vehicle speed is less than about 6 mph (10 km/h).
● A shift position other than P is selected.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’
front and rear bumpers.
● The following situations may occur during use.
• Depending on the shape of the object and other factors, the de tection dis-
tance may shorten, or detection may be impossible.
• Detection may be impossible if static objects draw too close to the sen- sor.
• There will be a short delay between static object detection an d display
(warning buzzer sounds). Even at low speeds, there is a possibi lity that
the object will come within 11.9 in. (30 cm) before the display is shown
and the warning buzzer sounds.
• It might be difficult to hear the buzzer due to the volume of the audio sys- tem or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of
other systems.

Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting it. Pay partic-
ular attention to the following objects:
●Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low objects
● Tall objects with upper sections projecting outwards in the dir ection of your
vehicle
■ Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is frozen. (Thawing t he area will resolve this problem .)
In especially cold weather, if a sensor is frozen the sensor di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● 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
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ult rasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandst orm
● When an object that cannot be detected is between the vehicle a nd a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
●
When a sensor or the area around a
sensor is extremely hot or cold.

If the orientation of a sensor has been changed due to a collis ion or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the car ried load
● If the vehicle cannot be driven in a stable manner, such as whe n the vehicle
has been in an accident or is malfunctioning
● When a tire chains, compact spare tire or an emergency tire pun cture repair
kit is used
■ Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may opera te even
though there is no possibility of a collision.
● 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 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 up or down a steep slope
● If a sensor is hit by a large amount of water, such as when dri ving on a
flooded road
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is coated with a sheet of spray or heavy rain
● When driving in inclement weather such as fog, snow or a sandst orm
●
When driving on a narrow road
● When strong winds are blowing

WARNING
■Cautions regarding the use of the system
There is a limit to the degree of recognition accuracy and cont rol perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicl e’ surroundings
and driving safely.
■ To ensure the system can operate properly
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not damage the sensors, and always keep them clean.
● Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-
less antenna near a radar sensor.
● Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by your Toyota dealer.
If the front or rear bumper needs to be removed/installed or replaced, con-
tact your Toyota dealer.
● Do not modify, disassemble or paint the sensors.
● Do not attach a license plate cover.
● Keep your tires properly inflated.
■ When to disable the function
In the following situations, disable the function as it may operate even
though there is no possibility of a collision.
● Failing to observe the warnings above.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor a rea.
Doing so may result in the sensor malfunctioning.
● 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
the sensors as doing so may cause a sensor to malfunction.
