GLA 250, GLA 250 4MATIC: as a temporary
measure, if the recommended fuel is not
available, you may also use regular unleaded
gasoline with an octane rating of 88 AKI/
93 RON.
All other models: 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 performance and increase fuel
consumption. Avoid driving at full throttle and
sudden acceleration. Never refuel using fuel
with a lower AKI.
Information on refueling ( Y
page 170).
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
prevention of residue buildup. gasoline
must only be mixed with additives recom-
mended by Mercedes-Benz. Comply with
the instructions for use on the product
label. More information about recommen-
ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels that have additives.
The quality of the fu el available in some coun-
tri
es may not be sufficient. Residue could
build up in the injection system as a result. In
such cases, and in consultation with an
authorized Mercedes-Benz Center, the gaso-
line may be mixed with the cleaning additive
recommended by Mercedes-Benz. You must
observe the notes and mixing ratios specified
on the container. Fuel consumption information
H Environmental note
CO 2
(carbon dioxide) is the gas which scien-
tists believe to be principally responsible 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 envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO 2
emis-
sions by driving carefully and having it serv-
iced 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 ful-
fill the prescribed service intervals. Do not
change the engine oil or oil filter in order to
achieve longer replacement intervals than
those prescribed. You could otherwise
cause engine damage or damage to the
exhaust gas aftertreatment.
Follow the instructions in the service inter-
val display regarding the oil change. Other-
wise, 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 377).
The engine oils are matched to the perform-
ance of Mercedes-Benz engines and serviceService products and filling capacities 379

intervals. You should therefore only use
engine oils and oil filters that are approved for
vehicles with maintenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Cen-
ter. Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.
Model MB-Freigabe
or MB-
Approval
All models

Use only SAE 0W-40 or SAE 5W-40 engine oils
for Mercedes-AMG vehicles.

tainers.

including the oil filter.

Additives
! Do no t use any additive s in th e engin e oil.
This could damag e th e engine. Engine oil viscosity
Visco sity describe s th e flo w characteristics
of a fluid . If an engin e oil has a high viscosity,
this mean s that it is thick ; a low viscosit y
mean s that it is thin.
Selec t an engin e oil wit h an SA E clas sif ication
(viscosity) suitable for th e prevailing outside
temperatures . The table sho ws you whic h
SA E classification s are to be used. The low-
temperature characteristics of engin e oils
can deteriorat e significantly, e.g. as a result
of aging, soo t and fuel depo sits. It is therefor e
strongly recommended that you carry out reg -
ular oil changes usin g an approve d engin e oil
wit h th e appropriat e SA E classification .
Brake fluid
G WARNIN G
The brak e fluid constantl y absorbs moisture
from th e air. This lower s th e boiling poin t of
th e brak e fluid . If th e boiling poin t of th e brak e
fluid is to o low, vapo r pockets may for m in th e
brak e system when th e brakes are applie d
hard. This would impair braking efficiency.
There is a ris k of an accident.
You should hav e th e brak e fluid renewed at
th e specifie d intervals.
When handlin g brak e fluid , observ e th e
important safet y note s on ser vic e products
( Y
page 377).
The brak e fluid chang e intervals can be foun d
