5-5. Using the driving support systems
detection distance may shorten,
or detection may be impossible.
Detection may be impossible if
static objects draw too close to the
sensor.
There will be a short delay
between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibility that the object
will come within 9.8 in. (25 cm)
before the display is shown and
the warning buzzer 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
sound of this system due to the
buzzers of other systems.
Conditions under which the
function may not function cor-
rectly
Certain vehicle conditions and the
surrounding 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 sen-
sor. (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 dis-
play may be displayed abnor-
mally, 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 vehi-
cles, or other loud noises produc-
ing 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 prop-
erly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the fol-
lowing objects:
Wires, fences, ropes, etc.
Cotton, snow and other materials
that absorb sound waves
Sharply-angled objects
Low objects
Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
