Information on refueling (
Additives
! Do not refuel with low-grade fuel and do
not use fuel additives that are not tested
and approved for Mercedes-Benz vehicles.
Damage to or malfunctions of the fuel
system may otherwise occur.
One of the main problems of poor fuel quality
is the forming of deposits that are created
during the gasoline combustion process.
Mercedes-Benz recommends that you use
branded fuels that have additives.
If you use fuels without these additives over
a longer period of time, carbon deposits may
build up. These deposits form at the inlet
valves and in the combustion chamber in
particular.
This could lead to engine problems, e.g.:
longer engine warm-up phase
R
uneven idle
R
engine noise
R
misfiring
R
loss of power
R
Carbon deposits may form if the availability
of gasoline with relevant additives is
insufficient (in certain regions). In this case,
Mercedes-Benz recommends additives
approved for use in Mercedes-Benz vehicles;
see http://bevo.mercedes-benz.com.
For a list of approved products, consult an
authorized Mercedes-Benz Center. Comply
with the instructions for use on the product
label.
Do not mix other fuel additives with fuel. This
causes unnecessary costs and could damage
the engine.

Flexible Fuel vehicles

Important safety notes
G
WARNING
E85 fuel (ethanol) and its vapours are
poisonous, highly flammable and highly
combustible. E85 fuel can cause serious
injury if ignited, if you come into contact with
it you or if you inhale fuel vapors. Avoid
inhaling E85 fuel vapors and avoid skin
contact with E85 fuel. Extinguish any open
flames before refueling. Keep sparks away
from E85 fuel, and do not smoke.
Flexible Fuel vehicles can be refueled with the
following fuel types:
premium-grade unleaded gasoline
R
E85 fuel
R
a mixture of E85 fuel and premium-grade
R
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 content of E85 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 your authorized Mercedes-Benz
Center that you are operating or have
operated the vehicle with E85 fuel.
Low outside temperatures
The starting procedure may take much longer
when operating the vehicle with E85 fuel at
outside temperatures below 32 ‡ (0 †).
E85 fuel is not suitable for use at outside
temperatures below -4 ‡ (-20 †).
