Warning segments for the right side of the
vehicle
At least one segment will light up as the vehicle
approaches an obstacle, depending on the vehi‐
cle's distance from the obstacle.
In addition, warning tones are emitted. When the
distance to the obstacle is sufficient, you will
hear an intermittent warning tone. The shorter
the distance to the obstacle, the shorter the fre‐
quency of the intermittent warning tones
becomes. When the minimum distance is
reached, you hear a continuous warning tone.
The warning display for each side of the vehicle is
divided into five yellow and two red segments.
