Parking Assist PARKTRONIC
Important safety notes
Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitor sthe area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not areplacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting aparking space. Make sure that there
are no persons, animals or object sinthe maneu-
vering area while maneuvering and parking in/
leaving parking spaces.
!When parking, pay particular attention to
object sabove or below the sensors, such as
flower pots or trailer drawbars. Parking Assist
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
object sthat absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of atruck or
ap neumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
Parking Assist PARKTRONIC is activated auto-
matically when you:
Rswitch on the ignition
Rshift the transmission to position h,kor
i
Rrelease the electric parking brake Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/h). It is reactiva-
ted at lower speeds.
Range of the sensors
General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhanging
loads, tail section
sorloading ramps of trucks.
:Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly,t aking care not to scratch
or damage them (
Ypage 265).

Radar sensors
The rada rsensors for Blind Spo tAssist ar einte-
grated into the rea rbum per. Make sure thatt he
bumpers ar efreef rom dirt, ice or slush. The
sensors must not be covered ,for exampl eby
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to the
bumpers, have the functio nofthe rada rsensors
checked at aquali fied specialist workshop.
