2017 MERCEDES-BENZ METRIS ECO mode

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.

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.

Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
GWARNING
If you are driving and reach through the steer- ing wheel to operate the adjustment knob,
you could lose control of the vehicle. There is
a risk of an accident and injury.
Only operate the adjustment knobs when thevehicle is stationary. Do not reach through the
steering wheel when driving.
You must observe the legal requirements for the
country in which you are currently driving when
operating the on-board computer.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer display only shows mes-
sages and warnings from certain systems. You
should therefore make sure your vehicle is oper-
ating safely at all times. If the operating safety of
your vehicle is impaired, stop the vehicle as
soon as possible, paying attention to road and
traffic conditions. Then consult a qualified spe-
cialist workshop.
The accuracy of the speedometer and odometer
displays is legally prescribed. Determining the
speed is dependent on the wheel size or the
rolling circumference of the wheels. If you
change the wheel size on your vehicle, make
sure it is assigned to the correct wheel size cat-
egory (
Ypage 277). If you change wheel size
category without recoding the control unit, the
speedometer indication will be inaccurate. Driv-
ing safety and driving systems may be impaired
or detect a malfunction and shut down.

Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor-
rectly can impair operating safety. Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found
under "Wheel and tire combinations" .
Information on your vehicle's tire pressure can
be found:
Rin the Tire and Loading Information placard on
the B-pillar, driver's side
Rin the tire pressure table inside the fuel filler
flap (Ypage 281)
Runder "Tire pressure tables" (Ypage 288)
Runder "Tire pressure" (Ypage 280)
Modifications to the brake system or wheels are
not permitted. The use of a spacer and brake
dust shields is not permitted. This invalidates
the general operating permit for the vehicle.
Further information on wheels and tires can be
obtained at any qualified specialist workshop.
Operation
Information for a journey
If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary
(
Ypage 280).
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tires are damaged. If you suspect that
a tire is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tires for damage. Hidden
tire damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tires and wheels checked at a
qualified specialist workshop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at a sharp angle. Otherwise, the
tires, particularly the sidewalls, can get dam-
aged.

Vehicle electronics
Tampering with the engine electron-
ics
!
Only have engine electronics and the corre-
sponding parts, such as control units, actua-
tors, sensors or connector leads, serviced at a
qualified specialist workshop. Otherwise, the
vehicle parts may wear more quickly. This can
lead to loss of the New Vehicle Limited War-
ranty.
Installing electrical or electronic
equipment
You and others can suffer health-related dam-
age through electromagnetic radiation. By using
an exterior antenna, a possible health risk
caused by electromagnetic fields, as discussed
in scientific circles, is taken into account. Only
have the exterior antenna installed by a qualified specialist workshop.
Electrical and electronic devices may have a
detrimental effect on both the comfort and the
operating safety of the vehicle. If equipment of
this kind is installed, its electromagnetic com-
patibility must be checked and verified.
If these devices are linked to functions associ-
ated with resistance to interference, they must
have type approval. This applies to the device or
its interfaces to the vehicle electronics, e.g.
charging brackets.
A telephone or two-way radio to be installed in
the vehicle must be approved. You can obtain
further information from any Mercedes-Benz
Commercial Van Center. For operation of mobile phones and two-way
radios, Mercedes-Benz recommends connec-
tion to an approved exterior antenna. This is the
only way to ensure optimum reception quality
inside the vehicle and to minimize mutual inter-
ference between the vehicle electronics, mobile
phones and two-way radios.
The transmission output of the mobile phone or
two-way radio may not exceed the following
maximum transmission output (PEAK):
