maneuvering. You could otherwise endanger
yourself and others.
G
Warning
Make sure that no persons or animals are in
the maneuvering range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid.
PARKTRONIC indicates visually and audibly
the distance between your vehicle and an
object.
Your vehicle features
two sound emitters with
different frequencies for the warning tones.
The warning ranges in front of and behind the
vehicle are indicated by different warning
tones.
PARKTRONIC is automatically activated when
the key is turned to position 2 in the ignition
lock, the parking brake is released and the
selector lever is moved to position D, N or R.
PARKTRONIC is deactivated automatically at
speeds above 11 mph (18 km/h).
PARKTRONIC is reactivated automatically at
speeds below 10 mph (16 km/h).
PARKTRONIC monitors the area around your
vehicle with sensors in the front and rear
bumpers.
Range of the sensors The sensors must be free of dirt, ice and
slush; otherwise, they may not function
correctly. Clean
the
sensors regularly, taking
care not to scratch or damage them
(Y page 163). Front sensors

If an obstacle is within this range, all
segments of
the
warning displays light up and
you hear a warning tone. If the distance
between the vehicle and the obstacle falls
below the minimum range, it is possible that
the distance may no longer be displayed.
! Pay particular attention to obstacles
above or below the sensors when parking,
such as flower pots or trailer towbars.
PARKTRONIC does not recognize such
objects when they are in the immediate
vicinity of the vehicle. You could damage
the vehicle or objects.
PARKTRONIC can suffer interference from:
R ultrasonic sources such as a lorry's
compressed-air brakes, an automatic car
wash or a pneumatic drill
R attachments to the vehicle, e.g. rear
mounted racks
R number plates (vehicle license plates)
that are not affixed flat against the
bumper
R dirty or icy sensors
Warning displays The warning displays show the distance
between the sensor and the obstacle.

The warning display is divided into five yellow
and two red segments for each side of the
vehicle. PARKTRONIC is operational if yellow
indicator segments 008A and 0086 light up.
There is a malfunction if only the red
segments of the warning display light up
(Y page 215).
The position of
the selector lever determines
whether the front and/or rear area is
monitored. Selector lever

One or more segments light up as the vehicle
approaches an obstacle, depending on the
vehicle's distance from the obstacle.
From the:
R
sixth segment, an intermittent warning
tone sounds for approximately
two seconds.
R seventh segment, a continuous warning
tone sounds. You have reached the
minimum distance. Driving systems
