4-5. Using the driving support systems
snow, dirt, etc. Remove the ice, snow,
dirt, etc., from the sensor to return the
system to normal.
Also, due to ice forming on a sensor at
low temperatures, a warning message
may be displayed or the sensor may not
be able to detect an object. Once the ice
melts, the system will return to normal.
■
If a battery terminal has been dis-
connected and reconnected
The system needs to be initialized. To
initialize the system, drive the vehicle
straight ahead for 5 seconds or more at
a speed of approximately 35 km/h (22
mph) or more.
■
Sensor detection information
●
The following situations may occur
during use.
• The sensor's detection areas are lim-
ited to the areas around the vehicle
front and rear bumpers.
• Depending on the shape of the object
and other factors, the detection dis-
tance may shorten, or detection may
be impossible.
• If an object is extremely close to a
sensor, it may not be detected.
• There will be a short delay between
object detection and display. Even at
low speeds, there is a possibility that
the object will come within the sen-
sor's detection areas before the dis-
play is 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 buzzer if
buzzers for other systems are sound-
ing.
■
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 pro-
jecting outwards in the direction of
your vehicle
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. Particular 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
sensor is extremely hot or cold.
●
On an extremely bumpy road, on an
incline, on gravel, or on grass.
●
When vehicle horns, vehicle detec-
tors, 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
