RKTRONIC Fu
nction of PARKTRONIC
PA RKTRONIC is an electronic parking assis tance
sy stem with ultrasonic sensors. The sy stem moni‐
to rs the area around your vehicle using sensors
on the front bumper and on there ar bumper.
PA RKTRONIC indicates visually and audibly the
dis tance between your vehicle and an object.
The warning ranges in front of and behind the
ve hicle are indicated bydiffere nt wa rning tones.
PA RKTRONIC is on ly an aid. It is not a substitu te
fo ryo u paying attention tothe sur roundings. Yo u
are alw aysre sponsible for safe manoeuvring,
parking and exiting a parking space. Make sure
th at there are no persons, animals or objects etc.
in the manoeuvring area while manoeuvring and
parking or exiting parking spaces.
Re quirements for automatic activation:
R The ignition is switched on.
R The parking brake has been released.
