Conditions under which the func-
tion may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect
objects. Particular 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
displayed 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
sensor 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 pro-

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

Detection range of the sensors
Approximately 60 cm (2.0 ft.)
Approximately 150 cm (4.9 ft.)
The diagram shows the detection range
of the sensors. Note that the sensors
cannot detect objects that are
extremely close to the vehicle.
The range of the sensors may change
depending on the shape of the object,
etc.
