Each warning indicator has six yellow and
two red segments.The gear selector lever position deter-
mines which warning indicator is activat-
ed.
As soon as the sensors detect an obstacle,
one or more segments light up, depending
on the distance. An intermittent acoustic
warning will also sound as the seventh seg-
ment comes on and a constant acoustic
warning lasting a maximum of
three seconds will sound for the eighth
segment.

!If all red segments light up in the warn-
ing indicators, a dirty sensor or a ultra-
sonic signal could be the reason.
Clean the sensors (
page 237).
After cleaning the sensors, switch
the ignition on.
