Gasoline

Fuel grade

!

Do not use diesel to refuel vehicles with a

gasoline engine. Do not switch on the igni-

tion 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 quali-

fied specialist workshop and have the fuel

tank and fuel lines drained completely.

!

Only refuel using premium-grade unlea-

ded gasoline with at least 91 AKI/95 RON

(91 octane).

!

Only use the fuel recommended. Operating

the vehicle with other fuels can lead to

engine failure.

!

Do not use the following:

R

E85 (gasoline with 85% ethanol)

R

E100 (100% ethanol)

R

M15 (gasoline with 15% methanol)

R

M30 (gasoline with 30% methanol)

R

M85 (gasoline with 85% methanol)

R

M100 (100% methanol)

R

Gasoline with metalliferous additives

R

Diesel

Do not mix such fuels with the fuel recom-

mended for your vehicle. Do not use addi-

tives. Engine failure may otherwise occur.

This does not include cleaning additives

for the removal and prevention of residue

build-up. Gasoline must only be mixed with

cleaning additives recommended by smart

(see "Additives"). For further information

inquire at any smart center.

!

To ensure the longevity and full perform-

ance of the engine, only premium-grade

unleaded gasoline must be used.

If standard unleaded gasoline is unavail-

able and you have to refuel with unleaded

gasoline of a lower grade, observe the fol-

lowing precautions:

R

Only fill the fuel tank to half full with

regular unleaded gasoline and fill the

rest with premium-grade unleaded gas-

oline as soon as possible.

R

Do not drive at the maximum speed.

R

Avoid sudden acceleration and engine

speeds over 3,000 rpm.

You will usually find information about the

fuel grade on the pump. If you cannot find the

label on the pump, ask the staff for assis-

tance.

i

For further information, consult a quali-

fied specialist workshop or on the Internet

at http://www.smartusa.com (USA only).

i

E10 fuel contains up to 10% bioethanol.

Your vehicle is E10-compatible. You can

refuel your vehicle using E10 fuel.

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 engine per-

formance and increase fuel consumption.

Avoid driving at full throttle and sudden

acceleration. Never refuel using fuel with a

lower octane rating.

Information on refueling (

Y

page 97).

Additives

!

Operating the engine with subsequently

added fuel additives can lead to engine

damage. Do not mix any fuel additives with

the fuel. This does not include additives

for the removal and prevention of residue

buildup. Gasoline must only be mixed with

additives recommended by smart. Comply

with the instructions for use on the product

label. For further information on recom-

mended additives, inquire at any smart

center.

smart recommends that you use fuel brands

that have additives.

The quality of the fuel available in some

countries may not be sufficient. Residue

could build up in the injection system as a

result. In this case, in consultation with a

smart center, the gasoline may be mixed with

the cleaning additive recommended by smart.

Fuel consumption information

H

Environmental note

CO

2

(carbon dioxide) is the gas which sci-

entists believe to be principally respon-

sible for global warming (the greenhouse

effect). Your vehicle's CO

2

emissions are

directly related to fuel consumption and

therefore depend on:

R

efficient use of the fuel by the engine

R

driving style

R

other non-technical factors, such as

environmental influences, road condi-

tions or traffic flow

You can minimize your vehicle's CO

2

emis-

sions by driving carefully and having it

serviced regularly.

The vehicle will use more fuel than usual in

the following situations:

R

at very low outside temperatures

R

in city traffic

R

on short journeys

R

in mountainous terrain

Engine oil

General notes

!

Never use engine oil or an oil filter of a

specification other than is necessary to

fulfill the prescribed service intervals.

Do not change the engine oil or oil filter in

order to achieve longer replacement inter-

vals than those prescribed. You could oth-

erwise cause engine damage or damage to

the exhaust gas aftertreatment.

Follow the instructions in the service

interval display regarding the oil change.

Otherwise, you may damage the engine and

the exhaust gas aftertreatment.

When handling engine oil, observe the impor-

tant safety notes on service products

(

Y

page 207).

The engine oils are matched to the perform-

ance of smart engines and service intervals.

You should therefore only use engine oils and

oil filters that are approved for vehicles

with maintenance systems.

Consult a smart center to view a list of

approved engine oils and filters. Or visit the

website http://bevo.mercedes-benz.com.

The table shows which engine oils have been

approved for your vehicle.

Engine oil viscosity

Viscosity describes the flow characteristics

of a fluid. If an engine oil has a high viscos-

ity, this means that it is thick; a low viscos-

ity means that it is thin.

Select an engine oil with an SAE (viscosity)

classification suitable for the prevailing

outside temperatures. The table shows you

which SAE classifications are to be used. The

low-temperature properties of engine oils

can be significantly impaired during oper-

ation due to, for example, aging or soot and

fuel accretion. It is therefore strongly rec-

ommended that you carry out regular oil

changes using an approved engine oil with

the appropriate SAE classification.

Brake fluid

When handling brake fluid, observe the

important safety notes on service products

(

Y

page 207).

The brake fluid change intervals can be found

in the Maintenance Booklet.

Only use brake fluid approved by Mercedes-

Benz according to MB Approval 331.0.

Information about approved brake fluid can

be obtained at any qualified specialist work-

shop or on the Internet at

http://bevo.mercedes-benz.com.

i

Have the brake fluid regularly replaced at

a qualified specialist workshop and the

replacement confirmed in the Maintenance

Booklet.

Coolant

General notes
!

Only add coolant that has been premixed

with the desired antifreeze protection.

You could otherwise damage the engine.

Further information on coolants can be

found in the Mercedes-Benz Specifications

for Service Products, MB BeVo 310.1, e.g. on

the Internet at

http://bevo.mercedes-benz.com. Or con-

tact a qualified specialist workshop.

!

Always use a suitable coolant mixture,

even in countries where high temperatures

prevail.

Otherwise, the engine cooling system is not

sufficiently protected from corrosion and

overheating.

i

Have the coolant regularly replaced at a

qualified specialist workshop and the

replacement confirmed in the Maintenance

Booklet.

Comply with the important safety precautions

for service products when handling coolant

(

Y

page 207).

The coolant is a mixture of water and anti-

freeze/corrosion inhibitor. It performs the

following tasks:

R

corrosion protection

R

antifreeze protection

R

raising the boiling point

If the coolant has antifreeze protection down

to -35 ‡ (-37 †), the boiling point of the cool-

ant during operation is approximately 266 ‡

(130 †).
The antifreeze/corrosion inhibitor concen-

tration in the engine cooling system should:

R

be at least 50 %. This will protect the

engine cooling system against freezing

down to around -13 ‡ (-25 †).

R

not exceed 50 % (antifreeze protection down

to -35 ‡ [-37 †]). Otherwise, heat will not be

dissipated as effectively.

smart recommends an antifreeze/corrosion

inhibitor concentrate in accordance with MB

Specifications for Operating Fluids 310.1 or

325.6.

Operating Fluids 310.1 and 325.6 can be mixed

together. An orange discoloration depending

on the mixing ratio does not affect the func-

tion.

i

When the vehicle is first delivered, it is

filled with a coolant mixture that ensures

adequate antifreeze and corrosion protec-

tion.

i

The coolant is checked with every main-

tenance interval at a qualified specialist

workshop.

Windshield washer system

General notes
!

Do not add distilled or de-ionized water

to the washer fluid container. Otherwise,

the level sensor may be damaged.

!

Only MB SummerFit and MB WinterFit

washer fluid should be mixed together. The

spray nozzles may otherwise become

blocked.

When handling washer fluid, observe the

important safety notes on service products

(

Y

page 207).

At temperatures above freezing:

X

Fill the washer fluid reservoir with a mix-

ture of water and windshield washer fluid,

e.g. MB SummerFit.

Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:

X

Fill the washer fluid reservoir with a mix-

ture of water and washer fluid, e.g. MB Win-

terFit.

The correct mixing ratio can be taken from

the information on the antifreeze protec-

tion container.

i

Add windshield washer fluid, e.g. MB

SummerFit or MB WinterFit, to the washer

fluid all year round.

Climate control system refrigerant

Important safety notes

The climate control system of your vehicle is

filled with refrigerant R‑134a.

The instruction label regarding the refrig-

erant type used can be found on the left, on the

underside of the hood.

!

Only the refrigerant R‑134a and the PAG

oil approved by Mercedes-Benz may be

used. The approved PAG oil may not be

mixed with any other PAG oil that is not

approved for R-134a refrigerant. Other-

wise, the climate control system may be

damaged.

Service work, such as topping up refrigerant

or replacing components, may only be carried

out by a qualified specialist workshop. All

applicable regulations must be adhered to,

SAE standard J639 included.

Always have work on the climate control sys-

tem carried out at a qualified specialist

workshop.

Refrigerant instruction label

The refrigerant instruction label:

R

is located at the front on the right on the

body frame.
