2017 MERCEDES-BENZ METRIS fuel cap

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
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
Rthe maximum permissible gross weight of
vehicle/trailer combination
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 303).
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 314).
Your vehicle behaves differently with a trailer
than without one.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capab ility
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 distance.
If you 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.
You will find weight information under "Te
chni-
cal data" (Ypage 314).
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.

Maintenance and care

Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning a long journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
GWARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres- sure monitors keep the tire valve open. This
can also result in tire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
!The pressure difference between tires on
any one axle must be no greater than 10 kPa
(0.1 bar/1.5 psi).
iThe specifications shown on the sample Tire
and Loading Information placard and tire
pressure table are examples. Tire pressure
data are vehicle-specific and may deviate
from the data illustrated here. The tire pres-
sure specifications that are valid for your vehi-
cle can be found on the Tire and Loading
Information placard and the tire pressure
table on the vehicle.
HEnvironmental note
Check the tire pressure regularly, at least
every 14 days.
General notes
You will find information on tire pressure for the vehicle's factory-mounted tires on the plates
described here.
The recommended tire pressure for various
operating conditions can be found on the Tire
and Loading Information placard on the B-pillar
on the driver's side of the vehicle or on the tire
pressure table inside the fuel filler flap. Further information on tire pressure can be
obtained at a qualified specialist workshop.

GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight of
the vehicle including fuel, tools, spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight if applicable. The gross
vehicle weight must never exceed the permissi-
ble gross weight (GVWR) specified on the
B-pillar on the driver's side (
Ypage 303).
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permitted gross
weight of the fully laden vehicle (weight of the
vehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight if
applicable). The permissible gross weight is
specified on the vehicle identification plate on
the B-pillar on the driver's side (
Ypage 303).
Maximum weight of the laden vehicle
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa are the
equivalent of 1 psi. Another tire pressure unit is
bar. 100 kilopascals (kPa) are the equivalent of
1 bar.
Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of the
tire more precisely.
Curb weight
The weight of a vehicle with standard equipment
including the maximum filling capacity of fuel,
oil, and coolant. It also includes the air-condi-
tioning system and optional equipment if these
are installed on the vehicle, but does not include
passengers or luggage.
Maximum tire load
The maximum tire load in kilograms or pounds is
the maximum weight for which a tire is
approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (Pounds per square inch)
Standard unit of measurement for tire pressure.
Aspect ratio
Relationship between tire height and width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's surface.
Tire pressure is specified in pounds per square
inch (psi), in kilopascal (kPa) or in bar. Tire pres-
sure should only be corrected when the tires are
cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
Rif the vehicle has not been driven further than
1 mile (1.6 km)
Tire tread
The part of the tire that comes into contact with
the road.
Tire bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
tire bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, a roof rack or a high-performance bat-
tery, are not included in the curb weight and theweight of the accessories.

Wheels and tires
Z

TIN (Tire Identification Number)
A unique identification number which can be
used by a tire manufacturer to identify tires, for
example for a product recall, and thus identify
the purchasers. The TIN is composed of the
manufacturer identification code, tire size, tire
model code and manufacturing date.
Load bearing index
The load bearing index (also load index) is a code
that contains the maximum load bearing capa-
city of a tire.
Traction
Traction is the result of friction between the tires
and the road surface.
TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Distribution of the vehicle occupants
The distribution of vehicle occupants over des-
ignated seat positions in a vehicle.
Maximum permissible payload weight
Nominal load and goods/luggage load plus
68 kg (150 lb s)multiplied by the number of
seats in the vehicle.
Changing wheels
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes under "Mounting a wheel" (
Ypage 297).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
If your vehicle's tire configuration allows, you
can rotate the tires according to the intervals in
the tire manufacturer's warranty book in your
vehicle documents. If no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 miles (5,000 to 10,000 km) or earlier if
tire wear requires. Do not change the direction
of rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is rota-
ted. Avoid oily or greasy cleaning agents.
Check the tire pressure and reactivate the tire
pressure monitor if necessary.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount a spare wheel against the direc-tion of rotation. Observe the time restriction on
use as well as the speed limitation specified on
the spare wheel.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tires
from contact with oil, grease and fuel.

Gasoline
Fuel grade
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
!Only refuel using unleaded premium grade
gasoline with at least 91 AK I/95 RON.
!Only use the fuel recommended. Operating
the vehicle with other fuels can lead to dam-
age to the fuel system, engine and exhaust
system.
!Do not use the following:
RE15 (gasoline with 15% ethanol)
RE85 (gasoline with 85% ethanol)
RE100 (100% ethanol)
RM15 (gasoline with 15% methanol)
RM30 (gasoline with 30% methanol)
RM85 (gasoline with 85% methanol)
RM100 (100% methanol)
RGasoline with metalliferous additives
RDiesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.

iE10 fuel contains an admixture of up to 10%
bioethanol. Your vehicle is E10 compatible.
You can refuel your vehicle with E10 fuel.
iYou will generally find information about the
fuel grade on the filling pump. If there is no
identification on the filling pump, consult a
gas station attendant.
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce the engine's
performance and increase fuel consumption.
Avoid driving at full throttle and sudden accel-
eration. Never refuel using gasoline with a lower
AKI/RON rating.
iIn some countries, the available gasoline
may not be sufficiently low in sulfur. This fuel can temporarily produce unpleasant odors,
especially on short journeys. The odors are
reduced as soon as sulfur-free fuel (sulfur
content < 10 pp m) is used again fo rrefueling.
For more information about refueling
(
Ypage 132).
Fuel additives
!Operating the engine with subsequently
added fuel additives can cause engine dam-
age. Do not mix fuel additives with fuel. This
does not include additives for the remo val a
nd
prevention of deposits. Gasoline can only be
mixed with additives recommended by
Mercedes-Benz. Follow the instructions in the
product description. You can find further
information on recommended additives in any
Mercedes-Benz Commercial Van Center.
Mercedes-Benz recommends using brand-name
fuels with additives.
If you use fuels without these additives for a long
period of time, deposits can form. This primarily
forms on the inlet valve and in the combustion
chamber.
In some countries, the available fuel grade may
be inadequate. Residue could build up in the fuel
injection system as a result. In this case, in con-
sultation with a Mercedes-Benz Commercial
Van Center, the fuel should be mixed with the
cleaning additive recommended by Mercedes-
Benz. You must observe the notes and mixing
ratios indicated on the container.
Do not add other fuel additives to the fuel. This
results in unnecessary costs and can damage
the engine.
Information on fuel consumption
HEnvironmental note
CO
2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO
2emissions are directly related to
fuel consumption and therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it serv-
iced regularly.
Only for certain countries: the respective cur-
rent consumption and emission values of your
vehicle can be found in the COC papers (EC
CERTIFICATE OF CONFORMITY). These docu-
ments are supplied when the vehicle is deliv-
ered.
Consumption figures were found in the currently
valid respective version:
Rfor vehicles up to and including the Euro 4
standard according to EU Directive
80/1268/EEC
Rfor vehicles from the Euro 5standard accord-
ing to regulation (EC) no. 715/2007
Rfor vehicles from the Euro 6 standard accord- ing to regulation (EC) no. 595/2009
Fuel consumption depends on:
Rthe vehicle version
Rthe style of driving
Rthe operating conditions
Rthe type or quality of the fuel used
The vehicle will use more fuel than usual in the
following situations:
Rat very low outside temperatures
Rin city traffic
Rduring short journeys
Ron mountainous terrain
Rwhen towing a trailer
Observe the advice in the "Protection of the
environment" section to keep fuel consumption
low (
