Gasoline
Fuel grade
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
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 qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
!Only refuel using unleaded premium grade
gasoline with at least 91 AKI/95 RON.
iE10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
!Only use the fuel recommended. Operating
the vehicle with other fuels can lead to dam-
age to the fuel system, engine and exhaust
system.
!Do not use the following:
RGasoline with more than 10% ethanol
RE100 (100% ethanol)
RGasoline with methanol
RM100 (100% methanol)

Do not mix such fuels with the fuel recom-
mended for your vehicle.
!To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of a lower grade, observe the following pre-
cautions:
ROnly fill the fuel tank to half full with regular unleaded gasoline and fill the rest with pre-
mium-grade unleaded gasoline as soon as
possible.
RDo not drive at the maximum speed.
RAvoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the fuel pump. If you cannot find the
label on the fuel pump, ask the gas station staff.
iFor further information, consult a qualified
specialist workshop or visit
http://www.mbusa.com (USA only).
GLA 250, GLA 250 4MATIC: as a temporary
measure, if the recommended fuel is not avail-
able, you may also use regular unleaded gaso-
line with an octane rating of 88 AKI/93 RON.
All other models: as a temporary measure, if
the recommended fuel is not available, you ma
y
also use regular unleaded gasoline with an
octane rating of 87 AKI /91 RON.This may
reduc eengin eperformance an dincreas efuel
consump tion. Avoid driving at full throttle and
sudden acceleration. Never refuel using gaso-
line with a lower AKI.
iThe fuels you can use in your vehicle may
differ from the information in the Operator's
Manual depending on the country. The fuels
that have been approved for your vehicle can

Information on refueling (
Ypage 141).
Additives
!Operating the engine with fuel additives
added later can lead to engine failure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Comply with the instructions
for use on the product label. More information about recommended additives can be
obtained from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use bran-
ded fuels that have additives.
The fuel quality availabl e i
n some countries may
not be sufficient. Residue could build up in the
fuel injection system as a result. In such cases,
and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container.
Engine oil
General notes
!Do not use engine oil or an oil filter with
specifications deviating from those expressly
required for the prescribed service intervals.
Do not change the engine oil or oil filter in
order to set replacement intervals longer than
those prescribed. This could otherwise cause
damage to the engine or exhaust gas after-
treatment.
Follow the instructions on the service interval
display for changing the engine oil. This could
otherwise cause damage to the engine or
exhaust gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products (
Ypage 328).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You should therefore only use engine oils and oil filters that are approved for vehicles with main-
tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
