Index

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: R
Wash away fuel from skin immediately
using soap and water. R
If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay. R
If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing. R
Immediately change out of clothing which
has come into contact with fuel.

Gasoline
Fuel grade
! Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion 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 quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
! Only refuel using unleaded premium
grade gasoline with at least 91 AK I/
95 RON.
! Only use the fuel recommended. Operat-
ing the vehicle with other fuels can lead to
engine failure.
! Do not use the following: R
E85 (gasoline with 85% ethanol) R
E100 (100% ethanol) R
M15 (gasoline with 15% methanol) R
M30 (gasoline with 30% methanol) R
M85 (gasoline with 85% methanol) R
M100 (1 00% methanol) R
Gasoline with metalliferous additives R
Diesel
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 unavaila-
ble and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions: R
Only fill the fuel tank to half full with reg-
ular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible. R
Do not drive at the maximum speed. R
Avoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the sta ff for assis-
ta nce.366

fied specialist workshop or visit

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

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
