Driving and driving saf
ety sy stems Driving sy
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 on
radar and ultrasonic senso rsSome driving and driving sa
fety sy stems use
ra dar or ultrasonic sensors tomonitor the area
in front of, behind or next totheve hicle (depend‐
ing on theve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. The ultrasonic
sensors are located in the front and rear bump‐
ers. Keep these parts free of dirt, ice and slush
(/ page 509). The sensors must not be cov‐
ered, forex ample bybicycle rack s, ove rhanging loads,
sticke rs,fo il or foils toprotect against
st one chipping. Additional license plate brac kets
can li kewise impair the function of the ultrasonic
sensors. In theev ent of damage tothe bumpers
or radiator grille, or following a collision impact‐
ing the bumpers or radiator grille, ha vethe func‐
tion of the sensors checked at a qualified spe‐
cialist workshop. If the sensors are damaged,
some driving sy stems and driving saf ety sy stems
may no longer function proper ly. Overview of driving sy
