assistance function of Active Parking Assist is
stopped. The vehicle is parked and kept station-
ary without the driver having to depress the
brake pedal. The braking effect is canceled
when you depress the accelerator pedal. Active Parking Assist no longer supports you
with steering interventions and brake applica-
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 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.
XStart the engine.
XSwitch on the turn signal in the direction in
which you are pulling away.
XShift the transmission to position Dor R.

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 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.
Rif the camera lens is dirty or obstructed.
Observe the notes on cleaning (Ypage 267).
Rif the rear of the vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop. 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 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-mount

ed 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 277). 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.
Switching the rear view camera on or
off
XTo switch on: make sure that the key is in
position 2in the ignition lock.
XShift the transmission to position R.
On vehicles with a tailgate, the rear view cam-
era flap opens. The audio display shows the
area behind the vehicle. The rear area shown
is divided by guide lines.

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 needto brake additionally, to not depress the brake
pedal constantly, but periodically.
Observe the notes on ESP
®trailer stabilization
(Ypage 67).
Driving tips
If the trailer begins to swing from side to side:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
iYou can reduce the risk of the trailer swing-
ing and rocking by retrofitting anti-roll bars or trailer stability programs. Further information
is available at your authorized Mercedes-Benz
Van Dealer.
RMaintain a greater distance than you would
when driving without towing a trailer.
RAvoid sudden braking. Apply the brakes gen-
tly at first to allow the trailer brake to overrun.
Then, increase the brake force quickly.
RThe figures for the gradient climbing capabil-
ities from a standstill refer to sea level. When
driving in mountainous areas, note that the
power output of the engine, and with it its
gradient climbing capability, decrease with
increasing altitude.
Coupling up a trailer
Trailer coupled ready for use
XMake sure that the selector lever of the auto-
matic transmission is in position P.
XOn vehicles with an automatic transmission,
ensure that the transmission is in position P.
XEngage the vehicle's parking brake.
XClose all doors.
XPosition the trailer horizontally behind your
vehicle.
iThe height of the ball neck changes accord-
ing to the load on the vehicle. In this case, use
a trailer with a height-adjustable trailer draw-
bar.
XCouple the trailer.
XEstablish all electrical and other connections to the trailer. When doing so, hook the break-
away cable of the trailer into the eyelet on the
ball coupling.
XRemove the objects that are preventing the
trailer from rolling, e.g. wheel chocks.
XRelease the trailer parking brake.
iThe subharness of the vehicle has a cable
connection to the brake lamp indicator lamp.
Observe the maximum permissible trailer
dimensions (width and length).
Most federal states and all Canadian provinces
require by law:
Rsafety chains between the towing vehicle and the trailer. The chains should be cross-wound
under the trailer drawbar. They must be fas-

tened to the vehicle's trailer coupling, not to
the bumper or the axle.
Leave enough slack in the chains. This allows
you to drive round tight corners.
Ra separate brake system for certain types of
trailer.
Ra safety shut-off for braked trailers. Find out
the specific requirements according to the
applicable laws.
If the trailer becomes detached from the tow-
ing vehicle, the safety shut-off applies the
trailer brakes.
Towing a trailer
There are numerous legal requirements con-
cerning the towing of a trailer, e.g. speed restric-
tions. Many states require a separate functional
braking system for your trailer once a certain
weight limit is exceeded. For reasons of safety,
it is recommended that all trailers use a sepa-
rate functional braking system. Make sure yourvehicle/trailer combination complies with local
laws. This not only means where you live, but
also anywhere you are driving to. Information on
this can be obtained from the police and local
authorities.
Observe the following when towing a trailer:
RPractice driving around bends, stopping and
backing up at a place where there is no traffic.
This enables you to gain experience and get
used to the new handling characteristics.
RBefore driving, check:
-that the trailer tow hitch and ball coupling
are secure
-that the safety switch for a braked trailer is
functioning properly
-that the safety chains are secure and not
damaged
-that the electrical connections are secure
-that the lights are working
-that the wheels are in good order and the
tire pressure is correct
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer is equipped with a separate func-
tional braking system, check before each
journey whether the brakes are functioning
correctly.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 244).
RWhen driving with a trailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to crosswinds and
requires cautious steering.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the force on the
brake pedal.
RIf the automatic transmission repeatedly
shifts between gears when driving on inclines,
restrict the shift range. Select shift range
4,3 ,
2 o

r 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
RWhen driving on a downhill gradient, shift to a
low gear and take advantage of the engine's
braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-conditioning system is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switching the airflow and the temperature of
the air conditioning to the maximum level.
Open the windows if necessary.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com- bination you need an additional distance
before you can return to your original lane.

Speedometer
If you change the wheel size on your vehicle,
make sure it is assigned to the correct wheel
size category (
Ypage 277). If you change wheel
size category without recoding the control unit,
the speedometer indication will be inaccurate.
The current vehicle speed may then be higher
than the speed displayed in the speedometer.
The speed can also be shown in the display in
the form of a digital speedometer:

iIn some countries, a warning sounds and/or
the display shows a message when the vehi-
cle reaches the maximum legally permissible speed limit, e.g. at 75 mph (120 km/h).
Tachometer
!
Do not drive in the overrevving range, as this
could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption
of your vehicle and harms the environment as
a result of increased emissions.
The red band in the tachometer indicates the
engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached.
Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Please bear in mind that the outside tempera-
ture display shows the air temperature meas-
ured and not the road temperature.
The display shows the outside temperature in
the header:
