Introduction

!
To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline may be used.
If there is no premium-grade unleaded
gasoline available and regular unleaded
gasoline must be used,
please 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.
R if the vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above 3000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than 00C3 of the pedal travel.
! Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Only refuel using premium-grade unleaded
gasoline with a minimum octane rating of 91.
Reformulated Gasoline (RFG) and/or
unleaded gasoline with additives can be used.
The concentration of additives in the fuel,
however, must not exceed 10%, e.g.:
R Ethanol
R TAME
R ETBE
R IPA
R TBA
For MTBE, the concentration should not
exceed 15%.
The concentration of methanol in gasoline,
including other additives, must not exceed
3%.
Using mixtures of methanol and ethanol is not
permitted. Gasohol, a mixture of 10% ethanol
and 90% unleaded gasoline, may be used. All of these mix fuels must fulfill the fuel
requirements, e.g.:
R
knock resistance
R boiling point
R vapor pressure
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.

authorized Mercedes-Benz Center or on

Information on refueling (Y page 153).
AMG vehicles
! Only refuel using super-grade unleaded
gasoline with at least 98 RON/88 MON
that conforms to European standard
EN 228 or an equivalent specification.
You could otherwise impair engine output
or damage the engine.
! Premium-grade unleaded gasoline with
an octane rating of 95 RON/85 MON may
be used as a temporary measure if the
recommended fuel is not available. This
may reduce engine performance and
increase fuel consumption. Do not drive at
full throttle.
! Regular unleaded gasoline with an octane
rating of 91 RON/82.5 MON may also be
used as an emergency measure if the
recommended fuel is not available.
Doing so results in noticeably higher fuel
consumption, and the engine power output
is noticeably reduced. Avoid driving at full
throttle.
If only regular unleaded gasoline with an
octane rating of 91 RON/82.5 MON or
lower is available, you must have the
vehicle adapted to this fuel at a qualified
specialist workshop. 352
