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. The indicator lamp in the switch
lights up and the system switches off automatically!
A dirty sensor could be the reason. See page 378 for
instructions on cleaning the sensors in the bumpers.
After cleaning the sensors, turn electronic key in starter
switch to position 2. If the defect continues to be
displayed, have the system checked at your authorized
Mercedes-Benz Center.
