Sensor detection information
■
The following situations may occur dur-
●
ing use.
• The sensors may be able to only detect
objects near the front and rear bumpers.
• Depending on the shape of the object
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

4-5. Using the driving support systems
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-

People may not be detected if they are
wearing certain types of clothing.
