4-5. Using the driving support systems
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.
● It may be difficult to hear the sound of this
system due to the buzzers of other sys-
tems.
● If the meter malfunctions, the buzzer may
not sound.
■ 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 displayed 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.
● 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.
● When strong winds are 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 such as a towing eye-
let, transport hook, bumper protector,
bumper trim, bicycle carrier or snow-
removal device (snow plow) is installed
near the sensor.
● 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.
