2020 MERCEDES-BENZ METRIS tow bar

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 com-
ing loose from the wheel rim.
SidewallThe 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
the weight of the accessories.
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 iden-
tify 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
capacity 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 á in (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 weightNominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Changing wheels
Rotating the wheels
! 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"
(Y page

298).
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
available, 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 rotated. 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
hydroplaning. You will only gain these benefits
if the correct direction of rotation is observed. Changing wheels

!
Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel
system due to contaminated fuel.
i E10 fuel contains an admixture of up to
10% bioethanol. Your vehicle is E10 compat-
ible. You can refuel your vehicle with E10
fuel.
i You can obtain information on fuel grades
at a qualified specialist workshop or at a gas
station. If there is no identification on the
filling pump, consult a gas station attendant.

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 removal
and prevention of deposits. Gasoline can
only be mixed with additives recommended
by Mercedes-Benz. Follow the instructions
in the product description. You can find fur-
ther information on recommended additives
in any Mercedes-Benz Commercial Van Cen-
ter.
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 consultation with a Mercedes-Benz
Commercial Van Center, the fuel should be
mixed with the cleaning additive recommen-
ded by Mercedes-Benz. You must observe the
notes and mixing ratios indicated on the con-
tainer.
Do not add other fuel additives to the fuel.
This results in unnecessary costs and can
damage the engine. Information on fuel consumption H
Environmental note
CO 2 (carbon dioxide) is the gas that accord-
ing to the current state of knowledge is
mainly responsible for the heating of the
earth's atmosphere (greenhouse effect). The
CO 2 emissions of your vehicle vary in direct
correspondence with the fuel consumption
and is therefore dependent on:
R the efficient utilization of the fuel by the
engine
R the respective style of driving
R other non-technical factors, such as envi-
ronmental influences, condition of the
road or traffic flow, for example
You can help to minimize CO 2 emissions
with a conservative driving style and regular
maintenance of your vehicle .
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 cur-
rently valid respective version: R for vehicles with exhaust gas standard Euro
6 as per directive (EC) no. 715/2007
R for vehicles with exhaust gas standard
EURO VI as per directive (EC) no. 595/2009
Fuel consumption depends on:
R the vehicle version
R the style of driving
R the operating conditions
R the fuel type and fuel grade used
The vehicle will use more fuel than usual in the
following situations:
R at very low outside temperatures
R in city traffic
R during short journeys
R on mountainous terrain
R when towing a trailer
Observe the advice in the "Protection of the
environment" section to keep fuel consump-
tion low

Reduce the load on shorter roof carriers pro-
portionately. The maximum load per pair of
roof carrier supports is
110 lbs (50 kg). The
maximum load of a rail carrier bar is 220 lbs
(100 kg).
Loading guidelines and other information con-
cerning load distribution and load securing can
be found in the "Transporting" section
(Y page 242). Trailer tow hitch
General notes Mercedes-Benz recommends having a trailer
tow hitch retrofitted at an authorized
Mercedes-Benz Van Dealer.
Use only a trailer tow hitch that has been tes-
ted and approved specially for your vehicle by
the distributor named on the inside of the
front cover. Only use a ball coupling for your
Metris trailer tow hitch if it has been approved
for your vehicle. You can also find information
on the permitted dimensions of the ball cou-
pling on the identification plate of the trailer
tow hitch.
You can obtain advice from a qualified special-
ist workshop. Also observe the information on
towing a trailer in the "Driving and parking"
section (Y page

168).
Trailer loads Make sure that you adhere to the local legal
requirements for trailer loads.
The permissible weights and loads which can-
not be exceeded can also be found:
R in your vehicle documents and
R on the identification plates of the trailer
hitch, the trailer and the vehicle
(Y page

304)
You will find the basic values approved by the
manufacturer in the following table. If the val-
ues differ, the lowest value applies.
Make sure that you adhere to the weight
restrictions by having the weight checked on a
calibrated weighbridge. Permissible gross
