The driver is alw aysre sponsible for maintaining
a safe dis tance totheve hicle in front, forve hicle

in lane. Pay attention tothe tra ffic conditions at
all times and inter vene when necessa ry. Be
aw are of the limitations rega rding the safe use of
th ese sy stems.
Driving sy stems can neither reduce therisk of

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 as well as radar or ultrasonic sensors
to monitor the area in front of, behind or next to
th eve hicle.
Ke ep the areas around the sensors and cameras
free of dirt, ice or slush (/ page319). 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 and camera
sy stems, in particular.
In theeve nt of dama geor a se vere 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

obs tacle visually and audibly.
Pa rking Assist PARKTRONIC is on lyan aid. It is
not a substitute foryo ur attention tothe sur‐

vring and parking remains with you. Make sure
th at there are no persons, animals or objects in
th e manoeuvring area while manoeuvring and
parking in/exiting parking spaces.
The passive side impact pr otection also warns
yo u of obs tacles tothe side. During the parking
procedure or manoeuvring, objects are de tected
as theve hicle drives past. If yousteer in the
direction of a de tected obs tacle and there is a
ri sk of a lateral collision, a warning is issued. In
order for an object on the side tobe de tected,
th e sensors in the front and rear bumper must
fi rs t de tect the object while you are driving past
it.
In order for front or rear obs tacles tothe side to
be displa yed, theve hicle must firs t tr avel a dis‐
ta nce of at least half a vehicle length. Once the
ve hicle has tr avelled one vehicle length, obs ta‐
