Rear center sensor
■When multiple obstacles are detected in front and behind the
vehicle at the same time
The buzzer will change in the following manner.
● If an obstacle has been detected within 1.5 ft. (45 cm) of the front
or 2.8 ft. (85 cm) in rear of t he vehicle (a continuous buzzer is
sounding), and a new obstacle is detected at the other end of the
vehicle, the buzzer w ill sound 7 times then 1 continuous buzzer.
● If an obstacle has been detected within 1.5 ft. (45 cm) of the front
or 2.8 ft. (85 cm) in rear of t he vehicle (a continuous buzzer is
sounding), and a new obstacle is detected in the same way at th e
other end of the vehicle, the buzzer will sound 3 times then 1
continuous buzzer.
■Detection range of the sensors
Approximately 5.9 ft. (180 cm)
Approximately 2.0 ft. (60 cm)

WARNING
■Sensor detection information
Pay particular attention to the following instances in where th is may occur.
Failing to do so way result in the vehicle being unable to be d riven or parked
safety and possibly cause an accident.
● The sensor’s detection areas are limited to the areas around the vehicle’s
front corner and rear bumpers.
● Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
• The sensor is frozen. (Thawing the area will resolve this prob lem.)
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, mot orcycle
engines, air brakes of large vehicles, or other loud noises pro ducing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
• A backlit license plate, license plate holder, etc., are insta lled.
• People may not be detected if they are wearing certain types a nd color-
ing of clothing.
• People, animals, and moving objects may not be able to be detected.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.

2744-5. Using the driving support systems
WARNING
●The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play.
Even at slow speeds, there is a possibility that the obstacle w ill come
within the sensor’s detection areas before the display is shown and the
warning beep sounds.
• Thin posts or objects lower than the sensor may not be detecte d for col-
lision when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or
air flow noise of air conditioning system.

NOTICE
■When using intuitive parking assist-sensor
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyot a dealer.
● A beep does not sound when you turn the main switch on.
● The intuitive parking assist operation display flashes, and a beep sounds
when no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows continuously without a beep.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■ 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.

■Area displayed on screen
The rear view monitor system
displays an image of the view
from the bumper of the rear
area of the vehicle.
The image adjustment proce-
dure for the rear view monitor
system screen is the same as
the procedure for adjusting the
screen. (P. 3 3 3 )
• The area displayed on the
screen may vary according to
vehicle orientation conditions.
• Objects which are close to either corner of the bumper or under
the bumper cannot be dis-
played.
• The camera uses a special lens. The distance of the image that
appears on the screen differs
from the actual distance.
• Items which are located higher than the camera may not be disp layed
on the monitor.

●Using the camera
If dirt or foreign matter (such as water droplets, snow, mud, e tc.) is
adhering to the camera, it cannot transmit a clear image. In th is
case, flush it with a large quantity of water and wipe the came ra
lens clean with a soft and wet cloth.
■Differences between the scr een and the actual road
The distance guide lines and the vehicle width guide lines may not
actually be parallel with the div iding lines of the parking space, even
when they appear to be so. Be sure to check visually.
The distances between the vehicle width guide lines and the lef t
and right dividing lines of the parking space may not be equal, even
when they appear to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road sur-
faces. In any of the following situations, there is a margin of error
between the fixed guide lines on the screen and the actual dis-
tance/course on the road.
● When the ground behind the vehicle slopes up sharply
The distance guide lines will
appear to be closer to the vehi-
cle than the actual distance.
Because of this, objects will
appear to be farther away than
they actually are. In the same
way, there will be a margin of
error between the guide lines
and the actual distance/course
on the road.

2804-5. Using the driving support systems
●When the ground behind the ve hicle slopes down sharply
The distance guide lines will
appear to be further from the
vehicle than the actual dis-
tance. Because of this, objects
will appear to be closer than
they actually are. In the same
way, there will be a margin of
error between the guide lines
and the actual distance/course
on the road.
● When any part of the vehicle sags
When any part of the vehicle
sags due to the number of pas-
sengers or the distribution of
the load, there is a margin of
error between the fixed guide
lines on the screen and the
actual distance/course on the
road.
■When approaching thre e-dimensional objects
The distance guide lines are displayed according to flat surfac ed
objects (such as the road). It i s not possible to determine the posi-
tion of three-dimensional object s (such as vehicles) using the vehi-
cle width guide lines and distance guide lines. When approachin g a
three-dimensional object that ext ends outward (such as the flatbed
of a truck), be careful of the following.
