PARKTRONIC
General notes
PARKTRONIC is an electronic parking aid. The
system is equipped with ultrasonic sensors in
the front and rear bumpers to monitor the area
around your vehicle. PARKTRONIC indicates vis-
uallya nd audibly the distance between your
vehicle and an object.
Your vehicle features two separate sound emit-
ters 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 activated automatically when
you:
Rturn the key to position 2in the ignition lock
Rrelease the parking brake and
Rmove the selector lever to D,Nor R
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is reactivated
at speeds below 10 mph (16 km/h).
Important safety notes
PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate surround-
ings. You are responsible for safe maneuvering,
parking and pulling away.W hen maneuvering,
parking and pulling away,m ake sure that there
are no persons, animals or object sinthe maneu-
vering area.
!Pay particular attention to obstacles above
or below the sensors when parking, such as
flower pots or trailer towbars. PARKTRONIC
does not recognizes uch objectswhen they
are in the immediate vicinity of the vehicle.
You could damage the vehicle or objects.
PARKTRONIC can suffer interference from:
Rultrasonic sources such as atruck's
compressed-air brakes, an automatic car
wash or apneumatic drill
Rattachments to the vehicle, e.g. rear moun-
ted racks
Rnumber plates (vehicle license plates) that
are not affixed flat against the bumper
Rdirty or icy sensors
Remove adetachable trailer coupling if it is no
longer required. PARKTRONIC measures the
minimum detection range to an obstacle from
the bumper, not the ball coupling.

The rear view camera may show obstacles in
perspectival distortion, incorrectly or not at all.
The rear view camera cannot display all objects
located very near and/or under the rear
bumper. It does not warn you ofacollision, per-
sons or objects.
Under the following circumstances, the rear
view camera will not function, or will function in
al imited manner:
Rif the tailgate or rear door is open
Rif it is raining very heavily or snowing, or it is
foggy.
Rat night or in very dark places
Rif the camera is exposed to very bright light.
White lines may appear in the camera image.
Rif the area is lit by fluorescent light or LED
lighting. The camera image may flicker.
Rif the camera lens fogs up, e.g. when driving
into aheated garage in winter, causing arapid
change in temperature.
Rif the camera lens is dirty or obstructed.
Observe the notes on cleaning (Ypage 257).
Rif the rear of the vehicle is damaged. In this
case, have the camera position and setting
checked at aqualified specialist workshop.
Do not use the rear view camera in these situa-
tions. You could otherwise injure others or dam-
age object sand the vehicle while parking and
maneuvering.
The field of vision and other functions of the rear
view camera may be restricted due to additional accessories on the rear of the vehicle (e.g.
license plate holder, rear-mounted bicycle
rack).
Guide lines are alwayss hown at road level. In
trailer mode, the guide lines are shown at the
level of the trailer coupling.
If you change wheel size, make sure they corre-
spond to the correctw heel size category
(
Ypage 267). If the category is changed without
recoding the control units in the vehicle, the rear
view camera cannot be precisely calibrated. The
guide lines at road level or at the level of the
trailer tow hitch will not be displayed correctly.
In vehicles with atailgate, the rear view camera
is protected from raindrops and dust by means
of aflap. When the rear view camera is activa-
ted, this flap opens.
The flap closes again when:
Ryou have finished the maneuvering process
Ryou switch off the engine For technical reasons, the flap may remain open

RBefore the journey, make sure that the ball
coupling is correctly installed and secured.
To do this, observe the operating instruc-
tions of the ball coupling manufacturer.
RDo not make any modification stothe ball
coupling or the trailer tow hitch.
You must observe the operating instructions
of the trailer tow hitch or ball coupling manu-
facturer.
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is arisk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal-
lation instructions .Make sure that the ball
coupling is correctly installed and secured
before every journey.
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is arisk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasingt he speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
You can attach carrier systems such as bicycle
racks or load-bearing implements on the ball
coupling. The maximum noseweight of 165 lb
(75 kg) applies when using carrier systems on
the ball coupling.
Always observe the operating instructions pro-
vided by the manufacturers of the trailer cou-
pling and the ball coupling.
Couple and decouple the trailer carefully. When backing up the towing vehicle, make sure
nobody is standin gbetween the vehicle and the
trailer. At
railer which is incorrectly coupled to the tow-
ing vehicle could break away.Ac orrectly cou-
pled trailer must be positioned horizontally
behind the towing vehicle.
Ensure that the following weights are not excee-
ded:
Rthe permissible noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
Rthe maximum permissible gross weight of

Where the values differ, the lowest is valid.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle in the "Technical
data" section (
Ypage 305).
Your vehicle behaves differently with atrailer
than without one.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris more susceptible to stron gcrosswinds
Rrequires more sensitiv esteering
Rhas alarger turnin gcircle
This may impair the handling characteristics.
