4 Reversing camera
% Depending on theve hicle's equipment, the
ra dar sensors are integ rated behind the
bumpers and/or behind thera diator grille. Some driving and driving saf
ety sy stems use
cameras and sensors tomonitor the area in
front of, behind or next totheve hicle.
Ke ep the areas around the sensors and cameras
free of dirt, ice or slush (/ page241). The cam‐
eras and sensors must not be co vered, forex am‐
ple bybicycle rack s, overhanging loads, sticke rs,
fo il or foils toprotect against stone chipping.
Ad ditional licence plate brac kets can impair the
function of the ultrasonic sensors, in particular.
In theeve nt of damage or a severe impact in the
area of the sensors, ha vethe function of the
sensors checked at a qualified specialist work‐
shop. Ha vedamage or stone chipping in the area
of the cameras repaired at a qualified specialist
wo rkshop. If the sensors or cameras are dam‐
aged, some driving sy stems and driving saf ety
