■ 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-
jecting outwards in the direction of
your vehicle
People may not be detected if they are
wearing certain types of clothing.
