CLA 250, CLA 250 Sport, CLA 250
4MATIC, CLA 250 Sport 4MATIC: as a tem-
porary measure, if the recommended fuel is
not available, you may also use regular unlea-
ded gasoline with an octane rating of 93 RO N.
All other mod els: as a temporary measure, if
the recommended fuel is not available, you
may also use regular unleaded gasoline wit h
an octane rating of 87 AK I/ 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 168).
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 fuel available in some coun-
tries 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 w ith 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
Flexible Fuel vehicles
Important safety notes
G WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.
G WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
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.Service products and filling capacities 367

Additives
! Do no t use any additive s in th e engin e oil.
This could damag e th e engine.
Engine oil viscosity
Viscosit y 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 classification
(viscosity) suitable for th e prevailing outside
temperatures . The table shows 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 deposits. 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 saf et y note s on servic e products
( Y
page 365).
The brak e fluid chang e intervals can be foun d
in th e Maintenance Booklet .
Only use brak e fluid approve d by Mercedes-
Benz in accordanc e wit h MB-Freigabe or MB -
Approval 331.0.
Information about approve d brak e fluid can
be obtained at any qualified specialist work-
shop or on th e Internet at
http://bevo.mercedes-benz.co m.
i Have the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Coolant
Important safety notes
G WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g.
on the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.Service products and filling capacities 369
Technical data Z

! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
page 365).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks: R
corrosion protection R
antifreeze protection R
raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡( -37 †), the boiling point of the cool-
ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †) .R
no t exceed 55 % (antifreeze protection
do wn to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
Mercedes-Benz recommends coolant or anti-
freeze/corrosion inhibitor concentrate in
accordance with MB Specifications for Ser-
vice Products 310.1.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
i The coolant is checked with every main-
tenance interval at a qualified specialist
workshop. Filling capacities Model Capacity

Windshield washer system
Important safety notes
G WARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
When handling washer fluid, observe the
important safety notes on service products
( Y
page 365).
At temperatures above freezing: X
Fill the washer fluid reservoir with a mixture
of water and windshield washer fluid, e.g.
MB SummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing: X
Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Winter-
Fit.
For the correct mixing ratio refer to the
information on the antifreeze reservoir.370

Climate control system refrigerant
Important safety notes The climate control system of your vehicle is
filled with refrigerant R ‑ 134a.
The instruction label regarding the refrigerant
type used can be found on the left, on the
underside of the hood.
! Only the refrigerant R ‑ 134a and the PAG
oil approved by Mercedes-Benz may be
used. The approved PAG oil may not be
mixed with any other PAG oil that is not
approved for R-134a refrigerant. Other-
wise, the climate control system may be
damaged.
Service work, such as topping up refrigerant
or replacing components, may only be carried
out by a qualified specialist workshop. All
applicable regulations must be adhered to,
SAE standard J639 included.
Always have work on the climate control sys-
tem carried out at a qualified specialist work-
shop.
