stems and your responsibility Yo
ur vehicle is equipped with driving sy stems
which assist you in driving, parking and manoeu‐
vring theve hicle. The driving sy stems are aids
and do not relie ve you of your responsibility per‐
ta ining toroad traf fic la w.Pay attention tothe traf
fic conditions at all times and inter vene
when necessa ry. Be aware of the limitations
re ga rding the safe use of these sy stems. Information about
radar senso rs Some driving and driving sa
fety sy stems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. Keep these
parts free of dirt, ice and slush (/ page 458).
The sensors must not be co vered, forex ample
by cycle rack s, overhanging loads, sticke rs,fo il
or foils toprotect against stone chipping. In the
eve nt of dama getothe bumpers or radiator
grille, or following a collision impacting the
bumpers or radiator grille, ha vethe function of
th era dar sensors checked at a qualified special‐
ist workshop. The driving sy stems and driving
saf ety sy stems may no longer function proper ly
