The
recommended octane number foryo ur vehi‐
cle can be found on the instruction label in the
fuel filler flap (→ page173).
E 300, E 350: onlyrefuel using super unleaded
petrol with at lea st98 RON if you wish toach‐
ie ve maximum engine output. Alternatively, you
can also refuel using premium grade petrol with
at lea st95 RON.
All models: as atemp orary measure, if there c‐
ommended fuel is not available, you may also
re fuel with regular unleaded petrol with an
octane number of at least 91RON. This may
re duce engine output and increase fuel con‐
sum ption.
Ne verre fuel using petrol with an even lo wer
RO N.
Fu rther information on fuel can be obtained at a
fi lling station or a qualified specialist workshop.

If yo u mix diesel fuel with petrol, theflash
point of the fuel mixture is lo werth an that of
pure diesel fuel.
While the engine is running, component
pa rts in theex haust sy stem may overheat
without warning. #
Neverre fuel using petrol in diesel
engines. #
Never mix petrol with diesel fuel. *
NO
TEDama gecaused bythe wrong fuel Even small amounts of
the wrong fuel could

engine and the emission control sy stem. #
Only refuel using sulphu r-free diesel
fuel that con form sto European stand‐
ard EN 590, or an equivalent specifica‐
tion.
In countries without sulphur-f ree diesel
fuel, refuel using only lo w-sulphur diesel 462

fuel with a sulphur content less
than
50 ppm. #
Vehicles without diesel particulate
fi lter: refuel using only diesel fuel with
a sulphur content less than 500 ppm.
Ne verre fuel with one of thefo llowing fuels:
R petrol
R marine diesel
R heating oil
R pure bio-diesel fuel or vege table oil
R paraf fin or kerosene
If yo u ha veacciden tally refuelled with the
wrong fuel: #
Do not swit ch the ignition on. #
Consult a qualified specialist workshop. The
following compatibility indication for fuel
applies to yourvehicle: 1
For diesel fuel with a maximum of 7% byvol‐
ume bio-diesel (fatty acid me thyl es ter)
Ac cording toEuropean standard EN 1694 2you
can find the compatibility indications at thefo l‐
lowing locations:
R onthe instruction label on the fuel filler flap
R onthe fuel pump or pump nozzle suitable for
yo ur vehicle thro ughout Europe
Information on low outside temperatures
Re fuel your vehicle with as much winter diesel
fuel as possible at the beginning of winter.
Before changing overto winter diesel fuel, the
fuel tank should be em pty, if possible. When first re
fuelling with winter diesel fuel, only refuel
using a small amount, e.g. toreser veleve l. The
fuel tank can be filled as usual when next refuel‐
ling.

WARNING Risk of an accident due to
va pour poc kets form ing in the brake sys‐
tem
The brake fluid cons tantly absorbs moi sture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va pour poc kets may form inthe brake sys‐
te m when the brakes are applied hard.
This impairs the braking ef fect. #
Have the brake fluid rene we d at the
specified inter vals. Ha
ve the brake fluid regularly replaced at a
