●

There is a short delay between when an object is detected and when the display and
buzzer operate. Even at slow speeds, there is a possibility that an object will come
within the detection range before the display is shown and the 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.

Intuitive parking assist object warning function (vehicles with Advanced
Park)

The object warning function informs the driver of the existence of objects along
the side of the vehicle, using a display and buzzer, if the objects are within the
estimated path of the vehicle.

Object

Calculated vehicle route

When the vehicle is moving, the side sensors or side cameras can detect objects.
While the vehicle is moving, if a detected object can no longer be detected by the
side sensors or side cameras, the location of the object relative to the vehicle is
estimated. If the object is determined to be in the estimated path of the vehicle, the
object warning function will operate.

6-2. Using the safe driving support functions

438

Object detected by side sensors or side cameras

The vehicle is stopped and objects along the sides of the vehicle are not
detected.

Objects are detected as the vehicle is moving.

Even though the objects are outside of the detection area of the side sensors or
side cameras, a warning is displayed and a buzzer sounds.

INFORMATION

■

Object warning function operating conditions

●

The vehicle moves about 23.0 ft. (7 m) after the hybrid system is started.

●

The R shift position is selected.

●

After the D shift position has been selected, the vehicle has moved 23.0 ft. (7 m) or
less.

●

Panoramic view main switch has been pressed and the center display is displayed.

●

The front or rear sensor detects a stationary object.

■

Detection of objects along the sides of the vehicle

●

Objects along the sides of the vehicle are not instantaneously detected. The location
of objects in relation to the vehicle is estimated after they are first detected by the front
or rear side sensors, or side cameras. Therefore, after the power switch is changed
to ON, even if an object is along the side of the vehicle, it may not be detected until
the vehicle has been driven a small amount and the side sensors or side cameras
completely scan the areas along the sides of the vehicle.

●

If a vehicle, person, animal, etc., is detected by a side sensors or side cameras, but then
leaves the detection area of the side sensors or side cameras, the system will assume
the object has not moved.

which cannot be detected by a front side sensor is
next to the vehicle.
In the situation shown in the following illustration,
even if the vehicle starts off, the vehicle on the
left will not be detected and the object warning
function will not operate.

●

When an object or person is in a position which cannot be detected by the side
sensors or side cameras.

●

When, after the side sensors have completed scanning the areas along the sides of
the vehicle, a vehicle, person, or other object approaches the side of the vehicle and
