the buzzer and the LCD display will alert the driver to the situation for 3 seconds before the system switches to its
normal working mode.
Note: Neither the LCD nor the buzzer will warn the driver of obstacles located in the detection zone of a
malfunctioning sensor.

Note that the LCD doesn't display a direction for obstacles located behind a malfunctioning sensor(s). See figure 2
below.

a) Warning Zones
Safety zone: 100 to 200cm between bumper and obstacle
