an object
A buzzer sounds when the sensors are
operating.
 The buzzer beeps faster as the vehi-
cle approaches an object. When the
vehicle comes within the following
distance of the object, the buzzer
sounds continuously:
Approximately 1.0 ft. (30 cm)
 When 2 or more objects are
detected simultaneously, the buzzer
sounds for the nearest object. If one
or more objects come within
approximately 1.0 ft. (30 cm) of the
vehicle, the buzzer will repeat a long
tone, followed by fast beeps.
 Automatic buzzer mute function:
After a buzzer begins sounding, if
the distance between the vehicle
and the detected object does not
become shorter, the buzzer will be
muted automatically. (However, if
the distance between the vehicle
and object is 1.0 ft. (30 cm) or less,
this function will not operate.)
The buzzer sounds volume can be
adjusted. (P.256)
