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.O therwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could resul tindamage to the
fuel system and the engine. Notify a
qualified specialist workshop and have the
fuel tan kand fuel lines drained completely.
! Only refuel using unleaded gasoline with
a minimum octane rating of 91.
! Only use the fuel recommended.
Operating the vehicle with othe rfuels can
lead to engine failure.
! Do no tuse 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 (100% methanol)
R Gasoline with metalliferous additives
R Diesel
Do not mix such fuels with the fuel
recommended for your vehicle. Do not use
additives. This can otherwise lead to engine
damage.T his does not include cleaning
additives for the removal and prevention of
residue build-up. gasoline may only be
mixed with cleaning additives
recommended by Mercedes-Benz; see
"Additives". You can obtain further
information from any authorized Mercedes-
Benz Center.
! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline must be used. If standard premium-grade unleaded
gasoline is unavailable and unleaded
gasoline of a lower grade is used for
refueling, observe the following
precautions:
R
only fill the fuel tank to half full with
regular 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 above 3000 rpm.
R never refuel using fuel with an octane
number lower than 87. Otherwise,
engine failure could occur.
Using mixtures of methanol and ethanol is not
permitted. E10 fuel or E15 fuel (unleaded
gasoline with 10% or 15% ethanol) can be
used.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for
assistance.
i For further information, consult a
qualified specialist workshop or on the
Internet at http://www.mbusa.com (USA
only).
Information on refueling (Y page 162).

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
recommended by Mercedes-Benz. Comply
with the instructions for use on the product
label.M ore information about
recommended additives can be obtained
from any authorized Mercedes-Benz
Center. Service products and filling capacities
353Technical data Z

Mercedes-Ben
zrecommends that you use
fuel brands that have the additives.
The quality of the fuel available in some
countries may not be sufficient. Residue
could build up as a result. In such cases, and
in consultation with an authorized Mercedes-
BenzC enter, the gasoline may be mixed with
the cleaning additive recommended by
Mercedes-Benz (part no. A000989254512).
You must observe the notes and mixing ratios
specified on the container.
Flexible Fuel vehicles Important safety notes
G
WARNING
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. 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.
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
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
R Immediately change out of clothing which
has come into contact with fuel. Flexible Fuel vehicles can be refueled with the
following fuel types:
R
premium-grade unleaded gasoline
R E85 fuel
R a mixture of E85 fuel and premium-grade
unleaded gasoline
i Flexible Fuel vehicles can be recognized
by the Ethanol up to E85 sticker on the
inside of the fuel filler flap.
Fuel consumption
The energy contentofE 85 fuel is less than
that of the same amount of premium-grade
gasoline. The amount of fuel consumed when
operating the vehicle with E85 fuel is
therefore higher than with premium-grade
gasoline.
Maintenance
Inform you rauthorized Mercedes-Benz
Cente rthat you are operating or have
operated the vehicle with E85 fuel.
Low outside temperatures
If the outside temperature is below 32 ‡
(0 †), the starting procedure can take
noticeably longer when operating with E85
fuel.
E85 fuel is not suitable for use at outside
temperatures under -4 ‡ (-20 †). Engine oil
General notes !
Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill 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
interval display regarding the oil change. 354
Service products and fillingc
apacitiesTechnical data

Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the
important safety notes on service products
(Y page 351).
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 maintenance
systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz
Center. Or visit the website
http://bevo.mercedes-benz.com.

approved for your vehicle. Model Engine

Do no tuse any additives in the engine oil.
This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside
temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as a result
of aging, soot and fuel deposits. It is therefore
strongly recommended that you carry out
regularo
il changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid
