Technical data

the fuel system. Even small amounts of the
wrong fuel could resultindamage to the
fuel system and the engine. Notify a
qualified specialist workshop and have the
fuel tankand 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 otherfuels can
lead to engine failure.
!Do notuse the following:
RE85 (gasoline with 85% ethanol)
RE100 (100% ethanol)
RM15 (gasoline with 15% methanol)
RM30 (gasoline with 30% methanol)
RM85 (gasoline with 85% methanol)
RM100 (100% methanol)
RGasoline with metalliferous additives
RDiesel
Do not mix such fuels with the fuel
recommended for your vehicle. Do not use
additives. This can otherwise lead to engine
damage.This 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:
Ronly fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
Rdo not drive at the maximum speed.
Ravoid sudden acceleration and engine
speeds above 3000 rpm.
Rnever 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.
iFor further information, consult a
qualified specialist workshop or on the
Internet at http://www.mbusa.com (USA
only).
Information on refueling (Ypage 151).
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.More information about
recommended additives can be obtained
from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends 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-
BenzCenter, 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.

Engine oil
General notes
!Never use engine oil or an oil filter of a
specificationotherthan 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.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the
important safety notes on service products
(Ypage 345).
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.
The table shows which engine oils have been
approved for your vehicle.

Additives
!Do notuse 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
regularoil changes using an approved engine
oil with the appropriate SAEclassification.
Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
fromthe air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
