You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapors. There is a risk of
fire and explosion.
Before you open the fuel filler cap or take hold
of the pump nozzle, touch the metallic vehicle
body. This discharges any electrostatic
charge that may have built up.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with agasoline engine. Do not switch on the ignitionif you accidentally refuel with the wrong fuel.Otherwise, the fuel will enter the fuel system.Even small amounts of the wrong fuel couldresult in damage to the fuel system and theengine. Notify a qualified specialist workshopand have the fuel tank and fuel lines drainedcompletely.
!Overfilling the fuel tank could damage thefuel system.
!Take care not to spill any fuel on paintedsurfaces. You could otherwise damage thepaintwork.
!Use a filter when adding fuel from a fuel can.The fuel lines and/or the fuel injection system
could otherwise be blocked by particles fromthe fuel can.
Do not get into the vehicle again during the refu-eling process. Otherwise, electrostatic chargecould build up again.
If you overfill the fuel tank, fuel could spray outwhen the fuel pump nozzle is removed.

General information
Pay attention to the important safety notes(Ypage 139).
The fuel filler flap is unlocked/locked automat-ically when you unlock/lock the vehicle with theSmartKey.
The position of the fuel filler cap is displayed
In accordance with European standard EN16942, you can find the following compatibilitylabels for fuel:
ROn the instruction label on the fuel filler flap ofyour vehicle
ROn the fuel pump or pump nozzle for yourvehicle, throughout Europe
CFor gasoline with a maximum ethanol con-tent of 5 vol. %
DFor gasoline with a maximum ethanol con-tent of 10 vol. %
!Damage to the emissions control systemcaused by fuel with too high a sulfur content
ROnly use sulfur-free fuel (sulfur content ≤10 ppm).
Unpleasant odors may be produced if the avail-able fuel is not sufficiently low in sulfur.
E 400 4MATIC:observe the information on sul-fur content on the instruction label on the fuelfiller flap.
All models:the recommended octane numberfor your vehicle can be found on the instructionlabel on the fuel filler flap.
E 300, E 350, E 350 4MATIC:only refuel usingsuper unleaded gasoline with at least 98 RON, ifyou wish to achieve maximum engine output.
Alternatively, you can also refuel using premiumgrade gasoline with at least 95 RON.
All models:as a temporary measure, if the rec-ommended fuel is not available, you may alsouse unleaded regular gasoline with at least:
RE 180, E 250, E 300 e:93 RON
RAll other models:91 RON
This may reduce engine performance andincrease fuel consumption.
Never refuel using gasoline with a lower RON.

Additives
!Operating the engine with fuel additivesadded later can lead to engine failure. Do notmix fuel additives with fuel. This does notinclude additives for the removal and preven-tion of residue buildup. gasoline must only bemixed with additives recommended byMercedes-Benz. Comply with the instructionsfor use on the product label. More informationabout recommended additives can beobtained from any authorized Mercedes-BenzCenter.
Mercedes-Benz recommends that you use bran-ded fuels that have additives.
The fuel quality available in some countries maynot be sufficient. Residue could build up in thefuel injection system as a result. In such cases,and in consultation with an authorizedMercedes-Benz Center, the fuel may be mixedwith the cleaning additive recommended byMercedes-Benz. You must observe the notesand mixing ratios specified on the container.
