Important safety notes
GWARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, stor-
age and disposal of service products on the
labels of the respective original contain-
ers. Always store service products sealed
in their original containers. Always keep
service products out of the reach of chil-
dren.
HEnvironmental note
Dispose of service products in an environ-
mentally responsible manner.
Service products include the following:
RFuels
RLubricants (e.g. engine oil, transmission
oil)
RCoolant
RBrake fluid
RWindshield washer fluid
RClimate control system refrigerant
Components and service products must be
matched. You should therefore only use prod-
ucts that have been tested and approved by
Mercedes-Benz.
Information on tested and approved products
can be obtained at a smart center.
You can recognize service products approved by Mercedes-Benz by the following inscrip-
tion on the containers:
RMB-Freigabe (e.g. MB-Freigabe 229.51)
RMB Approval (e.g. MB Approval 229.51)
Other designations or recommendations
indicate a level of quality or a specification in accordance with an MB Sheet Number (e.g.
MB 229.5). They have not necessarily been
approved by Mercedes-Benz.
iFor further information inquire at any
smart center.
Fuel
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and
explosion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating
before refueling.
GWARNING
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 cloth-
ing 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
without delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vom-
iting.
RImmediately change out of clothing
which has come into contact with fuel.

Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscos-
ity, this means that it is thick; a low viscos-
ity means that it is thin.
Select an engine oil with an SAE (viscosity)
classification suitable for the prevailing
outside temperatures. The table shows you
which SAE classifications are to be used. The
low-temperature properties of engine oils
can be significantly impaired during oper-
ation due to, for example, aging or soot and
fuel accretion. It is therefore strongly rec-
ommended that you carry out regular oil
changes using an approved engine oil with
the appropriate SAE classification.
Brake fluid
When handling brake fluid, observe the
important safety notes on service products
(
Ypage 207).
The brake fluid change intervals can be found
in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Coolant
General notes
!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.
!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.
iHave 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
(
Ypage 207).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
Rcorrosion protection
Rantifreeze protection
Rraising 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 concen-
tration in the engine cooling system should:
Rbe at least 50 %. This will protect the
engine cooling system against freezing
down to around -13‡(-25 †).
Rnot exceed 50 % (antifreeze protection down
to-35 ‡[-37 †]). Otherwise, heat will not be
dissipated as effectively.
smart recommends an antifreeze/corrosion
inhibitor concentrate in accordance with MB
Specifications for Operating Fluids 310.1 or
325.6.
