mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■ Sensor detection information
● The following situations may occur
during use.
• 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.
■ 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.
