■ Sensor detection information
● The sensor's detection areas are
limited to the areas around the
vehicle' front and rear bumpers.
● The following situations may occur
during use.
• Depending on the shape of the
object and other factors, the
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 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 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 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
4-5. Using the driving support systems
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 follow-
ing 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.
