Parking Assist PARKTRONIC
Functions of Parking Assist
PARKTRONIC
Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using four sensors on the
front bumper and four sensors on the rear
bumper. Parking Assist PARKTRONIC shows you
the distance between your vehicle and an obsta-
cle visually and audibly.
Parking Assist PARKTRONIC is only an aid. It is
not a substitute for your attention to the imme-
diate surroundings. You are responsible for safe
manoeuvring, parking and pulling away. Make
sure that there are no persons, animals or
objects in the manoeuvring area while manoeu-
vring and parking in/leaving parking spaces.
In the standard setting, an intermittent warning
tone sounds from a distance of 0.5 m to the
obstacle. From a distance of 0.4 m a continuous
warning tone sounds.
System limitations

account the following obstacles:
