
Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.

The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obsta-
cle, the buzzer sounds continuously.
• Front corner sensors: Approximately 30 cm (1.0 ft.)
• Rear corner sensors: Approximately 30 cm (1.0 ft.)
• Rear center sensors: Approximately 35 cm (1.2 ft.)

When 2 or more obstacles are detected simultaneously, the buzzer
system responds to the nearest obstacle. If one or both come within
the above distances, the beep will repeat a long tone, followed by
fast beeps.
Detection range of the sensors
1
Approximately 50 cm (1.6 ft.)
2
Approximately 60 cm (2.0 ft.)
3
Approximately 150 cm (4.9 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles that
are extremely close to the vehicle.
The range of the sensors may change
depending on the shape of the object
etc.
