• 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 1.0 ft. (30 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 sys-
tems.
■
Objects which the system 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.
Situations in which the system may not
■
operate properly
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, water drops 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.
●
When a sensor or the area around a sen-
sor is extremely hot or cold.
4-5. Using the driving support systems
On an extremely bumpy road, on an
●
incline, on gravel, or on grass.
●
When vehicle horns, vehicle detectors,
motorcycle engines, air brakes of large
vehicles, the clearance sonar of other
vehicles or other devices which produce
ultrasonic waves are near the vehicle
A sensor is coated with a sheet of spray
●
or heavy rain.
●
If objects draw too close to the sensor.
●
When a pedestrian is wearing clothing
that does not reflect ultrasonic waves (ex.
skirts with gathers or frills).
When objects that are not perpendicular
●
to the ground, not perpendicular to the
vehicle traveling direction, uneven, or
waving are in the detection range.
●
Strong wind is blowing
When driving in inclement weather such
●
as fog, snow or a sandstorm
●
When an object that cannot be detected
is between the vehicle and a detected
object
●
If an object such as a vehicle, motorcycle,
bicycle or pedestrian cuts in front of the
vehicle or runs out from the side of the
vehicle
If the orientation of a sensor has been
●
changed due to a collision or other
impact
●
When equipment that may obstruct a
sensor is installed, such as a towing eye-
let, bumper protector (an additional trim
strip, etc.), bicycle carrier, or snow plow
If the front of the vehicle is raised or low-
●
ered due to the carried load
If the vehicle cannot be driven in a stable
●
manner, such as when the vehicle has
been in an accident or is malfunctioning
