radio MERCEDES-BENZ METRIS 2017 MY17 Operator’s Manual

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The ignition system operates with a high volt- age. If you touch the live components, you
could receive an electric shock. There is an
increased risk of injury.
Never touch components of the ignition sys-
tem if:
Rthe engine is running or being started
Rthe key is in radio position or drive position
in the ignition lock
The live components of the ignition system are,
for example:
Rignition coils
Rspark plug connectors
Rdiagnostic sockets
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
If you have to carry out work in the engine com-
partment, only touch the following components:
Rhood
Roil dipstick
Rengine oil filler neck cap
Rwasher fluid reservoir cap
Rcoolant expansion tank cap

Maintenance and care

nificantly too low. The tire pressure monitor is
not malfunctioning.
RUSA only: if thehwarning lamp flashes for
60 seconds and then remains lit constantly,
the tire pressure monitor is malfunctioning.
The display also shows a message:
Ron vehicles without steering wheel buttons
(Ypage 201)
Ron vehicles with steering wheel buttons
(Ypage 217)
USA only: if the tire pressure monitor is mal-
functioning, it may be more than ten minutes
before the malfunction is shown. The htire
pressure warning lamp flashes for 60 seconds
and then remains lit. When the malfunction has
been rectified, the htire pressure warning
lamp goes out after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gage. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a pressure gage are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
If radio transmitting equipment (e.g. wireless
headphones, two-way radios) is operated inside
the vehicle or in the vicinity of the vehicle, this
can interfere with the operati
on of the tire pres-
sure monitor.
Checking the tire pressure electroni-
cally on vehicles with steering wheel
buttons
You can only check the tire pressure electroni-
cally on vehicles with steering wheel buttons.
Using the steering wheel buttons
XTurn the key to position 2in the ignition lock.
XPress the =or; button to select the
Servicemenu.
XUse the 9or: button to select TirePressure.
XPressato confirm.
The current tire pressure of each wheel is
shown in the display.
If the vehicle has been parked for over
20 minutes, the Tire pressure will be
displayed after driving a few minutesmessage appears. After a teach-in period, the tire pressure monitor
automatically detects new wheels or new sen-
sors. As long as a clear allocation of the tire
pressure value to the individual wheels is not
possible, the
Tire
PressureMonitorActivemessage is shown instead of the tire pressure
display. The tire pressures are already being
monitored.
Tire pressure monitor warning mes-
sages
If the tire pressure monitor detects a loss in
pressure in one or more tires, a warning mes-
sage is shown in the display. The hwarning
lamp lights up.
Vehicles without steering wheel buttons
RIf the Correct Tire Pressuremessage is
shown in the display, the tire pressure in at
least one tire is too low. The tire pressure
must be corrected at the next opportunity.
RIf the CheckTirePressureSoonmessage
is shown in the display, the tire pressure in
one or more tires has dropped significantly.
The tires must be checked.
RIf the Warning Tire Malfunc.message is
shown in the display, the tire pressure in one
or more tires has dropped suddenly. The tires
must be checked.
Vehicles with steering wheel buttons
RIf the Adjust Tire Pressuremessage is
shown in the display, the tire pressure in at
least one tire is too low. The tire pressure
must be corrected at the next opportunity.
RIf the Check Tiresmessage is shown in the
display, the tire pressure in one or more tires has dropped significantly. The tires must be
checked.
RIf the WarningTireMalfunctionmessage
is shown in the display, the tire pressure in
one or more tires has dropped suddenly. The
tires must be checked.
Always read and follow the instructions and
safety notes related to the display messages,
which can be found in the "Tires" section.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-

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):
Frequency rangeMaximum trans-
mission output

(f < 50 MHz)100 W
