Fu
nction of thera dar 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 386).
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
