2 light up red and theé symbol appears in
th e multifunction displa y,Pa rking Assist
PA RKTRONIC may ha vebeen deactivated due to
signal inter fere nce. Start theve hicle again and
ch eck if Parking Assist PARKTRONIC is working
at a dif fere nt location.
If a warning tone also sounds for appro ximately
two seconds everytime theve hicle is star ted, it
may be due toone of thefo llowing causes:
R The sensors are dirty: cleanthe sensors
and obser vethe no tes on care of vehicle
parts (/ page 302).
R Parking Assist PARKTRONIC has been
deactivated due toa malfunction: restart
th eve hicle. If the problem persists, consult a
qu alified specialist workshop.
Fu nction of the passive side impact pr otec‐
tion
Pa ssive side impact pr otection is an additional
Pa rking Assist PARKTRONIC function which
wa rnsth e driver about obs tacles at the side of
th eve hicle. A warning is issued when obs tacles
are de tected between the front and rear de tec‐ tion
range. In order for an object on the side to
be de tected, the sensors in the front and rear
bumper must firs t de tect the object while you
are driving past it.
During the parking procedure or manoeuvring,
objects are de tected as theve hicle drives past.
If yo usteer in the direction of a de tected obs ta‐
cle and there is a risk of a lateral collision, a
wa rning is issued and the segments light up in
colour in the displa y.
The segment colour changes depending on the
dis tance tothe de tected obs tacle:
R Yello w: appr oximately 30 - 60 cm
R Red:less than appr oximately 30 cm
In order for lateral front or rear segments tobe
displa yed, theve hicle must firs t tr ave l a dis tance
of at least half of theve hicle length. Once the
ve hicle has tr avelled the length of theve hicle, all
of the lateral front and rear segments can be dis‐
pla yed. 226
