Signal tones
When approaching an object, an intermittent
tone is sounded that indicates the position of
the object. For example, if an object is de-
tected to the left rear of the vehicle, a signal
tone sounds from the left rear speaker.
The shorter the distance to the object be-
comes, the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
