Flexible Fuel vehicles
Important safety notes
GWARNIN G
Fuel is highly flammable. If you handle fuel
incorrectly, there is aris kof fir eand explo-
sion .
You must avoi dfire, open flames, creating
sparks and smoking. Switc hoff th eengin e
and ,if applicable, th eauxiliary heating before
refueling.
GWARNIN G
Fuel is poisonous and hazardous to health.
Ther eis aris kof injury.
You must mak esure that fuel does no tcome
int ocontact wit hyour skin, eyes or clothing
and that it is no tswallowed. Do no tinhale fuel
vapors. Kee pfuel away from children .
If you or other scome int ocontact wit hfuel ,
observ eth efollowing:
RWash away fuel from skin immediately
usin gsoap and water.
RIf fuel comes int ocontact wit hyour eyes,
immediately rinse them thoroughly wit h
clean water. Seek medical assistanc ewith-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do no tinduce vomit -
ing .
RImmediately chang eout of clothing whic h
has come int ocontact wit hfuel .
Flexible Fuel vehicles can be refueled wit hth e
followin gfuel types:
Rpremium-grade unleaded gasolin e
RE85fuel
Ramixtur eof E8 5fuel and premium-grade
unleaded gasolin e
iFlexible Fuel vehicles can be recognize dby
th eEthanol up to E85 sticker on theinside of
th efuel filler flap .
Fuel consump tion
The energyconten tof E8 5fuel is less than that
of th esam eamoun tof premium-grade gasoline.
The amoun tof fuel consumed when operating
th evehicl ewit hE8 5fuel is therefor ehigher than
wit hpremium-grade gasoline.
Maintenance
Infor myour authorize dMercedes-Ben zCente r
that you are operating or have operate dth e
vehicl ewit hE8 5fuel .
Low outside temperatures
If th eoutside temperature is belo w32 ‡(0 †),
the starting procedure can take noticeably lon-
ger when operating with E85 fuel.
E85 fuel is not suitable for use at outside tem-
peratures under -4 ‡ (-20 †).
DEF
Important safety notes
Comply with the important safety notes for ser-
vice products when handling DEF (Ypage 383).
DEF is a water-soluble fluid for the exhaust gas
aftertreatment of diesel engines. It is:
Rnot poisonous
Rcolorless and odorless
Rnot flammable
When you open the DEF container, small
amounts of ammonia vapor may be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may experi-
ence a burning sensation in your eyes, nose and
throat. Coughing and watering of the eyes are
possible.
Do not inhale ammonia vapors. Fill the DEF tank
only in well-ventilated areas.
Low outside temperatures
DEF freezes at a temperature of approximately
12 ‡(-11 †). The vehicle is delivere dfrom th e
factory equippe dwit h a DEFpreheatin gsystem.
Winte roperation can thus be guaranteed even
at temperature sbelow 12 ‡(-11 †).

Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
Comply with the important safety notes for ser-
vice products when handling brake fluid
(
Ypage 383).
Only use brake fluid approved for Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake fluid regularly replaced at a
qualified specialist workshop in accordance
with the replacement intervals and the
replacement confirmed in the service report.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.
!Always use a suitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the service report.
Comply with the important safety notes for ser-
vice products when handling coolant
(
Ypage 383).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection dow n to
-35 ‡ (
-37 †), the boiling point of the coolant
during operation is approximately 266 ‡
(130 †).
