At a qualiꢀed specialist workshop

Depending on the country, the fuels you can use

in your vehicle may diꢂer 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.

#

Immediately rinse fuel oꢂ your skin with

soap and water.

&

WARNING Risk of ꢀre or explosion from

fuel

#

If fuel comes into contact with your eyes,

immediately rinse them thoroughly with

clean water. Seek medical attention

immediately.

Fuels are highly ꢁammable.

Notes on fuel quality for vehicles with a gasoline

engine

If you have accidentally refueled with the

wrong fuel:

Impairment of the longevity and performance

of the engine.

Note the instructions about operating ꢁuids

(/ page 328).

#

Do not switch on the vehicle.

If unleaded premium grade gasoline is unavail-

able and you have to refuel using unleaded

regular gasoline:

#

Consult a qualiꢀed specialist workshop.

*

NOTE Damage caused by the wrong fuel

If the available fuel is not suꢃciently low in sulfur,

this can produce unpleasant odors.

Even small amounts of the wrong fuel could

result in damage to the fuel system, the

engine and the emission control system.

#

Only ꢀll the fuel tank to half full with

unleaded regular gasoline and reꢀll as

soon as possible with unleaded premium

grade gasoline.

Only refuel with fuel that has at least the octane

number speciꢀed in the information label in the

fuel ꢀller ꢁap. Otherwise, engine output can be

reduced and fuel consumption increased.

#

Only refuel with low-sulfur spark-ignition

engine fuel.

#

Do not drive at the maximum design

speed.

For maximum engine output: Only refuel using

premium-grade unleaded gasoline with at least

91 AKI/95 RON.

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

ume. Your vehicle is suitable for use with E10

fuel.

#

Avoid sudden acceleration and engine

speeds over 3000 rpm.

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 with one of the following fuels:

necessary for the prescribed service

intervals.

Notes on engine oil

Observe the notes on operating ꢁuids

(/ page 328).

In some countries, the fuel available may not have

suꢃcient 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

and mixing ratios indicated on the tank.

#

Do not alter the engine oil or oil ꢀlter in

order to achieve longer change intervals

than prescribed.

#

Do not use additives.

Have the engine oil changed aꢄer the

prescribed intervals.

WARNING ‑ Risk of ꢀre and injury from

antifreeze

&

WARNING Risk of an accident due to

vapor pockets forming in the brake system

* Recommended for the lowest possible fuel con-

sumption.

If antifreeze comes into contact with hot com-

ponent parts in the engine compartment, it

may ignite.

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.

To achieve the lowest possible fuel consumption,

it is recommended to use the engine oil speciꢀca-

tions marked in the table for the lowest SAE vis-

cosity class. Observe any possible restrictions of

the approved SAE viscosity classes.

#

Allow the engine to cool down before

adding antifreeze.

#

Make sure that no antifreeze spills out

next to the ꢀller opening.

This causes the braking eꢂect to be impaired.

#

Have the brake ꢁuid renewed at the

speciꢀed intervals.

#

Thoroughly clean oꢂ any antifreeze from

component parts before starting the

vehicle.

WARNING ‑ 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.

Only use coolant that has been premixed

with the required antifreeze protection.

Have the coolant regularly replaced at a qualiꢀed

specialist workshop.

Information on coolant is available at the fol-

lowing locations:
