The obstacle may not be recognized if outside the
shaded sensor field, and no longer be indicated when
approaching it any closer (warning indicators go out).
Parktronic malfunction
All red segments of the warning indicators light up, and
a warning sounds for 3 seconds, if Parktronic does not
function properly.
A dirty sensor could be the reason. (See page 317 for
instructions on cleaning the sensors in the bumpers.)
After cleaning the sensors, turn electronic key in
steering lock to position 2. If the defect continues to be
displayed, have the system checked at your authorized
Mercedes-Benz Center.
