Beeps and obstacle distance
A beep sounds when an obstacle with which there is a danger of collision
is detected. As the vehicle moves closer to the obstacle, the interval of
the beep becomes shorter.
● When the following obstacle distances are reached, the beep changes
from intermittent to continuous:
• If the distance to the obstacle detected by the dual sensors or rear corner
sensors is less than 0.8 ft. (25 cm).
• If the distance to the obstacle detected by the back sensors is less than 1.1
ft. (35 cm).
● If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obstacles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.
● If multiple obstacles are detected in front and behind the vehicle at the
same time, the warning beep will change in the following manner:
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected near a different area of the vehicle, the warning beep will sound
6 beeps then one continuous beep.
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn-
ing beeps will sound 2 beeps then one continuous beep.
● You can change the volume of the warning beeps. (
