WARNINGARNING Risk of re or explosion from

fuel

Fuels are highly ammable.

Fire, open ames, smoking and creating

sparks must be avoided.

Before and during refueling, switch o

the vehicle and, if installed, the station-

ary heater.

WARNINGARNING Risk of injury from fuels

Fuels are poisonous and hazardous to your

health.

Do not swallow fuel or let it come into

contact with skin, eyes or clothing.

Do not inhale fuel vapor.

Keep children away from fuel.

Keep doors and windows closed during

the refueling process.

If you or other people come into contact with

fuel, observe the following:

Immediately rinse fuel o your skin with

soap and water.

If fuel comes into contact with your eyes,

immediately rinse them thoroughly with

clean water. Seek medical attention

immediately.

If you swallow fuel, seek medical atten-

tion immediately. Do not induce vomit-

ing.

Change immediately out of clothing that

has come into contact with fuel.

Flexible-fuel vehicles can be refueled with the fol-

lowing fuel types:

Premium grade unleaded gasoline

E85 fuel

A mixture of E85 fuel and premium grade

unleaded gasoline

Flexible-fuel vehicles can be identied by the

Ethanol up thanol up to E85o E85 sticker on the inside of the fuel

ller ap.

Depending on the country, the fuels you can use

in your vehicle may dier from the information in

the Operator's Manual. The fuels that have been

approved for your vehicle can be found on the

instruction label on the inside of the fuel ller ap.

NOTETE Damage caused by the wrong fuel

Even small amounts of the wrong fuel could

result in damage to the fuel system, the

engine and the emission control system.

Only refuel with low-sulfur spark-ignition

engine fuel.

This fuel may contain up to 10% ethanol by vol-

ume. Your vehicle is suitable for use with E10

fuel.

Never refuel with one of the following fuels:

diesel

Gasoline with more than 10% ethanol by

volume, e.g. E15, E85, E100

Gasoline with more than 3% methanol by

volume, e.g. M15, M30, M85, M100

Gasoline with additives containing metal

If you have accidentally refueled with the

wrong fuel:

Do not switch on the vehicle.

Consult a qualied specialist workshop.

If the available fuel is not suciently low in sulfur,

this can produce unpleasant odors.

Only refuel with fuel that has at least the octane

number specied in the information label in the

fuel ller ap. Otherwise, engine output can be

reduced and fuel consumption increased.

For maximum engine output:or maximum engine output: Only refuel using

premium-grade unleaded gasoline with at least

91 AKI/95 RON.

If the recommended fuel is not available, you may

also temporarily use regular unleaded gasoline

with an octane number of at least 87 AKI/

91 RON. This may reduce engine output and

increase fuel consumption.

Never refuel using gasoline with an even lower

RON.

NOOTETE Premature engine wear through

unleaded regular gasoline

Impairment of the longevity and performance

of the engine.

If unleaded premium grade gasoline is unavail-

able and you have to refuel using unleaded

regular gasoline:

Only ll the fuel tank to half full with

unleaded regular gasoline and rell as

soon as possible with unleaded premium

grade gasoline.

Do not drive at the maximum design

speed.

Avoid sudden acceleration and engine

speeds over 3000 rpm.

NOTETE Damage from use of unsuitable

additives

Even small amounts of the wrong additive may

lead to malfunctions occurring.

Only add cleaning additives recommen-

ded by Mercedes-Benz to the fuel.

Mercedes-Benz recommends that you use brand-

name fuels with additives.

In some countries, the fuel available may not have

sucient additives. Deposits could build up in the

fuel injection system as a result. In this case, in

consultation with an authorized Mercedes-Benz

Center, mix the fuel with the cleaning additive rec-

ommended by Mercedes-Benz. Observe the notes

than those which meet the specications

necessary for the prescribed service

NNoottes on bres on brakakee uiduid

Note the instructions about operating uids

(/ page 330).

WARNINGARNING Risk of an accident due to

vapor pockets forming in the brake system

The brake uid constantly absorbs moisture

from the air. This lowers the boiling point of

the brake uid. If the boiling point is too low,

vapor pockets may form in the brake system

when the brakes are applied hard.

This causes the braking eect to be impaired.

Have the brake uid renewed at the

specied intervals.

Have the brake uid replaced regularly at a quali-

ed specialist workshop.

Only use a brake uid approved by Mercedes-

Benz according to MB-Freigabe or MB-Approval

331.0.

WARNINGARNING ‑ Risk of re and injury from

antifreeze

If antifreeze comes into contact with hot com-

ponent parts in the engine compartment, it

may ignite.

Allow the engine to cool down before

adding antifreeze.

Make sure that no antifreeze spills out

next to the ller opening.

Thoroughly clean o any antifreeze from

component parts before starting the

vehicle.

NOOTETE Overheating at high outside temper-

atures

If an inappropriate coolant is used, the engine

cooling system is not suciently protected

against overheating and corrosion at high out-

side temperatures.

Only use coolant approved by Mercedes-

Benz.

Observe the instructions in the

Mercedes-Benz Specications for Oper-

ating Fluids 320.1.

Have the coolant regularly replaced at a qualied

specialist workshop.

WARNINGARNING ‑ Risk of re and injury from

windshield washer concentrate

Windshield washer concentrate is highly am-

mable. It could ignite if it comes into contact

with hot engine component parts or the

exhaust system.

Make sure that no windshield washer

concentrate spills out next to the ller

opening.

NOOTETE Damage to the exterior lighting due

to unsuitable windshield washer uid

Unsuitable windshield washer uid may dam-

age the plastic surface of the exterior lighting.

Only use windshield washer uid which is

also suitable for use on plastic surfaces,

e.g. MB SummerFit or MB WinterFit.

NOOTETE Blocked spray nozzles caused by

mixing windshield washer uids

Do not mix MB SummerFit and MB Win-

terFit with other windshield washer u-

ids.

Do not use distilled or de-ionized water. Other-

wise, the ll level sensor may be triggered errone-

ously.

Recommended windshield washer uid:

Above freezing point: e.g. MB SummerFit

Below freezing point: e.g. MB WinterFit

For the correct mixing ratio, refer to the informa-

tion on the antifreeze container.

USUSA:A: use only R‑134a refrigerant.

Canada:Canada: use only R‑1234yf refrigerant.

NOOTETE Damage to the climate control sys-

tem due to incorrect refrigerant compres-

sor oil

Only use refrigerant compressor oil that

has been approved by Mercedes-Benz.

Do not mix the approved refrigerant

compressor oil with a dierent refriger-

ant compressor oil.

Work on the climate control system may be car-

ried out only at a qualied specialist workshop. All

applicable regulations, as well as SAE standard

J639, must be adhered to.
