Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
:Detected parking space on the left

If the driver's seat belt is fastened and all doors
are closed, Active Parking Assist is activated
automatically when driving forwards. The sys-
tem is operational at speeds of up to approx-
imately 22 mph (35 km/h). While in operation,
the system independently locates and meas-
ures parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and are at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel and
at least 40 in (1.0 m) longer than your vehicle
Rthat are at right angles to the direction of
travel and at least 40 in (1.0 m) widerthan
your vehicle
iNote that Active Parking Assist cannot
measure the length of a parking space if it is at right angles to the direction of travel. You will
need to judge whether your vehicle will fit in
the parking space.
When the vehicle is driving at speeds of up to
approximately 20 mph (30 km/h), parking sym-
bol ;is shown as a status display in the header.
The syste m d
etects and differentiates between
parking spaces which are parallel or at right
angles to the direction of travel. When a parking
space is detected, an arrow appears next to
parking symbol ;to indicate which side the
parking space is on. The parking space is dis-
played while you are driving past it and until you
are approximately 50 ft (15 m) away from it.
Active Parking Assist displays parking spaces on
the passenger side as standard. The parking
spaces on the driver's side are only displayed if
you operate the turn signal on the driver's side.
When parking on the driver's side, you must
operate the turn signal until you have started
active parking assistance by pressing the a
button on the steering wheel.
Parking
GWARNING
If you leave the driver's seat when the vehicle is only being braked by Active Parking Assist,
the vehicle could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
Rthe battery is disconnected.
Rthe vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the driver's seat, always secure the vehicle against rolling away.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically during the park- ing process. You are responsible for braking in
good time.

tions. Once active parking assistance has been
stopped, you must steer and brake again your-
self. PARKTRONIC is still available.
Parking tips:
RThe way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. It
may be the case that Active Parking Assist
guides you too far into a parking space, or not
far enough into it. In some cases, it may also
lead you across or onto the curb. In this case, cancel the active parking assistance.
RYou can also select transmission position D
prematurely. The vehicle redirects and does
not drive as far into the parking space. If you
change direction too early, parking assis-
tance is canceled and Active Parking Assist is
stopped. It is then not possible to achieve a
sensible parking position from the current
position.
Exiting a parking space
In order that Active Parking Assist can assist you
when exiting the parking space:
Rthe border of the parking space must be high enough at the front and the rear. A curb stone
is too small, for example.
Rthe border of the parking space must not be
too wide. Your vehicle can be maneuvered
into a position at a maximum of 45° to the
starting position in the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0 m) must be available .
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically when exiting
from the parking space. You are responsible for braking in good time.

Rear view camera
General notes
On vehicles with a tailgate, the rear view camera
is next to the tailgate handle (Ypage 269).
On vehicles with rear doors, the rear view cam-
era is in the top of the license plate molding
(
Ypage 269).
The rear view camera is a visual parking aid. It
shows you the area behind the vehicle in the
audio display.
The area behind the vehicle is displayed in a
mirrored fashion, as in the rear-view mirror or
the exterior mirrors. The guide lines displayed
assist you in backing up.
160Driving systems
Driving an d parking

The message displays depend on the language
setting of the audio system. The following rear
view camera displays are examples.
Important safety notes
!Objects that are not at ground level appear
further away than they actually are, for exam-
ple:
Rthe bumper of the vehicle parked behind
Rthe drawbar of a trailer
Rthe ball coupling of a trailer tow hitch
Rthe tail-end of a truck
Rslanted posts
Only use the camera guide lines for orienta-
tion. Do not get any closer to objects than the
lowest horizontal guide line. You may other-
wise damage your vehicle and/or the object.
The rear view camera is only an aid. It cannot
replace your own awareness of the immediate
surroundings. You are responsible for safe
maneuvering and parking. Make sure that there
are no persons, animals or objects in the maneu- vering area while maneuvering and parking in
parking spaces.
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 of a collision, per-
sons or objects.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited 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, e.g. from fluorescent lamps or LED lighting.
The camera image may flicker.
Rif the camera lens fogs up, e.g. when driving
into a heated garage in winter, causing a rapid
change in temperature.
Rthe camera lens is dirty or obstructed.
Observe the notes on cleaning.
(
Ypage 269)
Rif the rear of the vehicle is damaged. In this case, have the camera position and
setting checked at a qualified specialist work-
shop.
Rthe display has pixel errors.
Have the display repaired or replaced if usa-
bility is significantly reduced due to pixel
errors.
Do not use the rear view camera in these situa-
tions. You could otherwise injure others or dam-
age objects and the vehicle while parking and
maneuvering.
The field of vision and ot

her 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 always shown 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 correct wheel size category
(
Ypage 279). 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 a tailgate, the rear view camera
is protected from raindrops and dust by means
of a flap. 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 briefly after the rear view camera has been
deactivated.

Towing a trailer
Notes on trailer towing
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question 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.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
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 correctly installed
and secured, it could come loose while driving and endanger other road users. There is a risk
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 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.
You can attach carrier systems such as bicycle
racks or load-bearing implements on the ball
coupling. The maximum load-bearing capacity
of 165 lb (75 kg) applies when using carrier sys-
tems 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 standing between the vehicle and the trailer.
A trailer which is incorrectly coupled to the tow-
ing vehicle could break away. A correctly 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

The applicable permissible values that may not
be exceeded can be found:
Rin your vehicle documents
Ron the type plates for the trailer tow hitch
Ron the type plates for the trailer
Ron the vehicle identification plate
(Ypage 305)
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 316).
Your vehicle behaves differently with a trailer
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 strong crosswinds
Rrequires more sensitive steering
Rhas a larger turning circle
This may impair the handling characteristics.
When towing a trailer, always adjust your speed
to suit the road and weather conditions. Drive
carefully. Maintain a safe dista nce.
If y

ou require any further explanation regarding
the information contained in the Operating
Instructions, please contact a Mercedes-Benz
Commercial Van Center.
General notes
RObserve the legally permitted maximum
speed for vehicle/trailer combinations in the
relevant country, state or Canadian province.
Before beginning the journey, check the trail-
er's documents for the maximum permitted
speed of your trailer.
This reduces the risk of accidents.
RInstall only an approved trailer coupling on
your vehicle. Only use a ball coupling for your Metris trailer tow hitch if it has been approved
for your vehicle. More information on the
availability, mounting and installation of the trailer electrics is available at any qualified
specialist workshop.
RThe trailer coupling is one of the most impor-
tant vehicle parts with regard to road safety.
Observe the notes on operation, care and
maintenance of the trailer tow hitch (see the
manufacturer's operating instructions).
RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not attach rented trailer tow hitches or
other detachable trailer tow hitches to the
bumper.
RMinimize the risk of damage to the ball cou-
pling. If you do not require the ball coupling,
remove it from the ball coupling recess.
Yo u w
ill find weight information under "Techni-
cal data" (Ypage 316).
The height of the ball neck changes according to
the load on the vehicle. If this is case, use a
trailer with a height-adjustable trailer drawbar.
Driving tips
The maximum permissible speed for vehicle/
trailer combination depends on the type of
trailer. Before beginning the journey, check the
trailer's documents for the maximum permitted
speed of your trailer. Observe the legally per-
mitted maximum speed in the relevant country, state or Canadian province.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer and it will con-
sume more fuel.
On long and steep downhill gradients, select a
lower gear.
iThis also applies if cruise control is activa-
ted.
This enables you to utilize the engine's braking
effect and you do not need to brake so heavily to keep the correct speed. This relieves the load on
the brake system and prevents the brakes from overheating and wearing too quickly. If you need
to brake additionally, to not depress the brake
pedal constantly, but periodically.
Observe the notes on ESP
®trailer stabilization
(Ypage 67).
