This fuel may contain up to10 %ethanol.
Yo ur vehicle is suitable for use with E10 fuel.
Do not refuel using:

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 140). This may reduce
engine output and increase fuel consum ption.
If yo uwa nt maximum engine output: only

Notes on brake fluid

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. Fu
