2020 MERCEDES-BENZ METRIS gas type

Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
DANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the
manufacturer's specifications. Any work on
the engine should therefore be carried out by
qualified and authorized Mercedes-Benz tech-
nicians.
The engine settings must not be changed
under any circumstances. In addition, all spe-
cific maintenance work must be carried out at
regular intervals and in accordance with the
service requirements of the dealer listed here
on the inside title page. Details can be found
in the Maintenance Booklet. Speed limiter
G
WARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed
could lead to tire damage or the tire burst-
ing. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe
the tire load rating and speed rating
required for your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the max-
imum permissible speed based on the tires
(tire and tire pressure). In particular, also observe the tire approval regulations for each
country.
You must not exceed the speed limit for the
tires indicated by the speed rating. The speed
rating is stated in the tire tables (Y page
302).
You can permanently limit the permissible
maximum speed of your vehicle, e.g. for driv-
ing on winter tires.
Mercedes-Benz recommends that you have
the maximum permissible speed programed at
a Mercedes-Benz Commercial Van Center.
Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programmed permissi-
ble maximum speed. Driving abroad
Service An extensive network of authorized Mercedes-
Benz Centers is also at your disposal when you
are traveling abroad. Nevertheless, please
bear in mind that service facilities or replace-
ment parts may not always be immediately
available. The relevant workshop directories
are available from any Mercedes-Benz Com-
mercial Van Center.
Fuel In some countries, only fuels with a higher sul-
fur content are available.
Unsuitable fuel can cause engine damage. You
will find information about fuel under "Service
products and capacities"

(Y page 306).
Low-beam headlamps General notes
When driving in countries in which traffic
drives on the opposite side of the road to the
country where the vehicle is registered, you
must switch the headlamps to symmetrical
low beam. This prevents oncoming traffic from
being blinded. Symmetrical low beam does not
illuminate as large an area of the edge of the
road. Driving tips

N The yellow Check Engine warning lamp lights up while the engine is running.
There may be a malfunction in the following vehicle systems:
R in the engine management
R in the transmission management
R in the fuel injection system
R in the exhaust system
R in the ignition system (for vehicles with a gasoline engine)
R in the fuel system
The emission limit values may be exceeded and the engine may be running in
emergency mode.
X Have the vehicle checked as soon as possible at a qualified specialist work-
shop. 6
N The yellow reserve fuel warning lamp is on while the engine is running.
The fuel level has dropped to the reserve range.
X Refuel at the nearest gas station. ?
N The red coolant warning lamp comes on while the engine is running.
On vehicles without steering wheel buttons, the coolant temperature gauge is at
the start of the bar display
(Y page 178).
On vehicles with steering wheel buttons, the coolant temperature gauge is at
the start of the scale in the instrument cluster ( Y page 40).
The temperature sensor for the coolant temperature gauge is faulty.
The coolant temperature is no longer being monitored. There is a risk of engine
damage if the coolant temperature is too high.
X Stop the vehicle immediately, paying attention to road and traffic conditions,
and switch off the engine. Do not continue driving under any circumstances.
X Secure the vehicle to prevent it from rolling away (Y page
138).
X Consult a qualified specialist workshop. Indicator and warning lamps in the instrument cluster

!
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
