Even small amounts of the wrong fuel could
re sult in damage tothe fuel sy stem, the
engine and the emission control sy stem.
#Only refuel with lo w-sulfur premium
grade fuel.
This fuel may contain up to10 %ethanol.
Yo ur vehicle is suitable for use with E10 fuel.
Do not refuel using:
RDiesel

RGasoline with additives con taining me tal
If yo u accidenta llyrefuel with the wrong fuel:
#Do not switch the ignition on.
#Consult a qualified specialist workshop.
Ifth eav ailable fuel is not suf ficiently low in sul‐
fur, this can produce unpleasant odors.
Only refuel with fuel, that has at least the octane
number specified in the information table in the
fuel filler flap (
→page 155). This ma yre duce
engine output and increase fuel consum ption.
If yo uwa nt maximum engine output: only
re fuel with unleaded premium grade gasoline
with an octane number of at least 91AKI/
95 RON.

TEPremature wear caused byunlea‐
ded regular gasoline
Unleaded regular gasoline can cause the
engine towe ar more quickly and impair lon‐

If unleaded premium grade gasoline is
una vailable and you ha vetorefuel using
unleaded regular gasoline:
Tech nical da ta395

#Onlyfill th e fuel tank tohalf full with
unleaded regular gasoline and refill as
soon as possible with unleaded pre‐
mium grade gasoline.
#Do not drive at the maximum speed.

Notes on brake fluid
Obser vethe no tes on operating fluids
(→page 394).
& WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid cons tantly absorbs moist ure
from the air. This lo wersthe boiling point of
th e brake fluid. Ifth e boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be
impaired.
#Ha ve the brake fluid rene we d at the
specified inter vals.
Ha ve the brake fluid regularly changed at a quali‐
fi ed specialist workshop.
Only use brake fluid appr ovedby Mercedes-Benz
according toMB-F reigabe or MB-Appr oval 33 1.0.
