Front corner sensors
■ When two or more obstacles are detected simultaneously
The buzzer system responds to the nearest zone.
■ 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 15.7 in. (400 mm) of the
front or 33.5 in. (850 mm) in rear of the vehicle (a continuous
buzzer is sounding), and a new obstacle is detected at the other
end of the vehicle, the buzzer will sound 7 times then one contin-
uous buzzer.
● If an obstacle has been detected within 15.7 in. (400 mm) of the
front or 33.5 in. (850 mm) in rear of the vehicle (a continuous
buzzer is sounding), and a new obstacle is detected in the same
way at the other end of the vehicle, the buzzer will sound 3 times
then one continuous buzzer.

Sensors that operate and detection range
The following diagrams show the se nsor detection range. Note that
sensors may not be able to detect obstacles that are extremely close
to the vehicle.

Perceptible area
Approx. 70.9 in. (1800 mm)
Approx. 33.5 in. (850 mm)
Approx. 23.6 in. (600 mm)
The diagram shows the detection range of the sensors. Note that the sen-
sors may not be able to detect obstacles that are extremely close to the vehi-
cle.
The range of the sensors may change depending on the shape of the object
etc.

228 2-4. Using other driving systems
■The Intuitive parking assist system can be operated when
●Front corner sensors:
• The engine switch is in the ON position.
• The shift lever is in R.
• The shift lever is not in P or R and vehicle speed is approximate 6 mph
(10 km/h) or less.
● Back and rear corner sensors:
• The engine switch is in the ON position.
• The shift lever is in R
■ Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A 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, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with intuitive parking assist sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When the bumper is damaged.

.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by a sensor to be closer
than they are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle
• A person near the vehicle (depending on the type of clothes worn)
• When the bumper is damaged.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ If the indicator is continuously on
Have the vehicle inspected by your Toyota dealer.
■ If the indicator remains blinking but do not sound the buzzer
Clean the sensors with soft cloth.
CAUTION
■Caution when using the intuitive parking assist
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● Do not attach any accessories within the sensor range.
NOTICE
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

Rear view monitor system
: If equipped
The rear view monitor system assists the driver by displaying an
image of the area behind the vehicle. The image is displayed in
reverse on the screen. This reversed im age is a similar image to the
one on the inside rear view mirror.
The rear view image is dis-
played on the inside rear view
mirror.
The screen is turned off if any
one of the following conditions
are met:
• The shift lever is shifted out of R
• The screen remains on for 5 minutes

■Rear view monitor guide lines
● Guide lines are displayed on the monitor.
Vehicle width extension guide lines (blue)
These lines indicate the estimated vehicle width extension.
Distance guide line (blue)
This line indicates a position on the ground about 3 ft. (1 m) behind on the
ground of the rear bumper of your vehicle.
Distance guide line (red)
This line indicates a position on the ground about 1.5 ft. (0.5 m) behind on
the ground of the rear bumper of your vehicle.
Vehicle center guide lines (blue)
These lines indicate the estimated vehicle center on the ground.

■The rear view monitor system can be operated when
The shift lever is in R and engine switch is ON.
■ Display mode
The rear view monitor display mode can be adjusted when the engine switc\
h
is in the ON position and the shift lever is in R.
●To temporarily turn off the monitor when it is on.
Push the button. The indicator should turn orange.
The monitor will automatically turn on again after the ignition is turned off
