and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between
object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas before the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due
to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if
buzzers for other systems are sounding.
■ Conditions under which the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
● There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
● A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
● A sensor is covered in any way.
● When a sensor or the area around a sen-
sor is extremely hot or cold.
● 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
parking assist sensors in the vicinity.
● A sensor is coated with a sheet of spray
or heavy rain.
● If a sensor is hit by a large amount of
water, such as when driving on a flooded
road.
● If the vehicle is significantly tilted.
● The vehicle is approaching a tall or
curved curb.
● If objects draw too close to the sensor.
■ Objects which may not be properly
detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
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 project-
ing outwards in the direction of your vehi-
cle
People may not be detected if they are
wearing certain types of clothing.
■ Detection range of the sensors
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect objects that are extremely close to
the vehicle.
