PARKTRONIC
Import ant safety notes
PARKTRONI Cis an electronic parking aid wit h
ultrasonic sensors. It monitors th earea around
your vehicl eusin gsix sensor sin th efron t
bumper and four sensor sin th erear bumper.
PARKTRONI Cindicates visually and audibly th e
distanc ebetween your vehicl eand an object.
PARKTRONI Cis only an aid. It is no t areplace -
men tfor your attention to your immediat esur -
roundings. You are always responsibl efor saf e
maneuvering, parking and exiting aparking
space. Mak esur ethat there are no persons,
animals or objects in th emaneuverin garea
while maneuverin gand parking in/leaving park -
ing spaces.

the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on a truck
or a pneumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to position h,kor
i
Rrelease the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles
:Example: sensors in the front bumper, right- hand side
:Approx. 24 in (approx. 60 cm) (corners)
;Approx. 32 in (approx. 80 cm) (corners)
=Approx. 35 in (approx. 90 cm) (center)
?Approx. 40 in (approx. 100 cm) (center)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them (
Ypage 239).
Minimum distance
CenterApprox. 8 in (approx. 20 cm)
CornersApprox. 8 in (approx. 20 cm)
If there is an obstacle within this range, the rel-
evant warning displays light up and a warning
tone sounds. If the distance falls below the min-
imum, the distance may no longer be shown.

cle
;Segments on the right-hand side of the vehi-cle

The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located on
the dashboard above the center air vents. The
warning display for the rear area is located on
the headliner in the rear compartment.
The warning display for each side of the vehicle
is divided into five yellow and two red segments.
PARKTRONIC is operational if yellow segments
showing operational readiness =light up.
The selected transmission position and the
direction in which the vehicle is rolling deter-
mine which warning display is active when the
engine is running.

One or more segments light up as the vehicle
approaches an obstacle, depending on the vehi-
cle's distance from the obstacle.
From the:
Rsixth segment onwards, you will hear an inter-
mittent warning tone for approximately two
seconds.
Rseventh segment onwards, you will hear a
warning tone for approximately two seconds.
This indicates that you have now reached the minimum distance.

Rear view camera
General notes
Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind the
vehicle with guide lines in the multimedia sys-
tem.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text shown in the multimedia system
depends on the language setting. The follow-
ing are examples of rear view camera displays
in the multimedia system.
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. Make sure
that there are no persons, animals or objects in
the maneuvering area while maneuvering and
parking in parking spaces.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner:
Rthe rear door is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,
e.g. when driving into a heated garage in win- ter
Rif the camera lens is dirty or obstructed.
Observe the notes on cleaning
(
Ypage 240)
Rif the rear of your vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop

The field of vision and other functions of the rear
view camera may be restricted due to additionalaccessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
Activating/deactivating the rear view
camera
XTo activate: make sure that the SmartKey is
in position 2in the ignition lock.
XMake sure that the "Rear view camera" func-
tion is selected in the multimedia system (see
Digital Operator's Manual).
XEngage reverse gear.
The multimedia system shows the area
behind the vehicle with guide lines. Sym-
bol :indicates that the "reverse parking"
function is active.
The image from the rear view camera is avail-
able throughout the maneuvering process.
XTo switch the function mode for vehicles
with trailer tow hitch: using the controller,
select symbol ;for "Coupling up a trailer".
Symbol ;is highlighted.
To deactivate: the rear view camera deacti-
vates if you shift the transmission to position j
or after driving forwards a short distance.
Displays in the multimedia system
The rear view camera may show a distorted view
of obstacles, show them incorrectly or not at all.
The rear view camera does not show objects in
the following positions:
Rvery close to the rear bumper
Runder the rear bumper
!Objects that are not at ground level appear
further away than they actually are, e.g.:
Rthe bumper of a parked vehicle
Rthe drawbar of a trailer
Rthe rear end of a truck
Ra post sticking up at an angle
Use the guide lines for orientation only. Do
not cross the lower guide line when approach-
ing objects.

Important safety notes
GWARNING
When differential locks are engaged on a firm,

Towing a trailer
Important safety notes
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 a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
GWARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-
tion is longer or angled differently. This could
seriously impair the driving characteristics
and the trailer can come loose. There is a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch.
GWARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
!If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may be
necessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chassis
frame.
The installation of a trailer tow hitch is only per-
missible if a towing weight is specified in your
vehicle documents. If this is not the case, then
the vehicle is not approved for the towing of a
trailer.
For more information, please contact a qualified
specialist workshop.
Please observe the manufacturer's operating
instructions for the trailer coupling if a detach-
able trailer coupling is used.
Exceeding the maximum permissible nose-
weight of the trailer drawbar on the ball coupling may cause damage.
Damage may be caused to the following:
RTowing vehicle
RTrailer
RBall coupling
RTrailer tow hitch
The vehicle/trailer combination could become
unstable.
If the noseweight used is lower than the mini-
mum permissible noseweight, the vehicle/
trailer combination could also become unstable.
