System Description

INFOID:0000000010478023

• The sonar sensor installed to the rear bumper detects obstacles around the bumper.
• The distance between a bumper and obstacles is informed to the driver with different frequency of buzzer.

Activation condition

The rear sensor activates and outputs the warning buzzer in the following conditions.
• Reverse signal ON (Power supply)
• Obstacle detection

Obstacle detection distance

• The sonar control unit controls the obstacle detection distance. The detection distance differs between the

corner sensor and the center sensor.

• Obstacle detection distance is indicated by a variable beep frequency.

Obstacle detection range image

NOTE:

• When an obstacle and distance of a bumper approach to less than 30 cm (11.8 in), a buzzer sound becomes a continuous sounds.
