2011 MERCEDES-BENZ C-Class temperature

into contact with your skin. Before refueling,
extinguish all naked flames. Never allow
sparks or smoking materials near ethanol.
Changing the fuel type
For best performance and driveability, it is
recommended that you use either one or the
other fuel. Avoid alternating regularly
between the two different types of fuel.
When changing the fuel type, make sure:
R the fuel level is below half full.
R the fuel level is above the reserve level. This
is identifiable by the fuel tank reserve
warning lamp not being lit.
R you add more than 5 gallons (20 liters) of
fuel.
R before refueling, you switch off the engine.
R the engine is started and operated for at
least five minutes immediately after
refueling.
These precautions and recommendations
should prevent any difficulties when starting
and operating the engine which otherwise
may be experienced before the engine has
fully adapted to the different fuel.
If, in spite of these recommendations, the
engine does not perform properly, add at
least 3 gallons (12 liters) of gasoline. This may
improve the running of the engine.
Fuel consumption
Ethanol fuel (E85) contains less energy per
gallon than gasoline. To ensure that the
engine performance with ethanol fuel (E85) is
similar to that when using gasoline, the
engine must burn more ethanol fuel. As a
result, it is to be expected that the fuel
consumption will increase when using
ethanol fuel (E85), compared to gasoline.
Maintenance
When you bring your vehicle for maintenance
or repairs, please inform your authorized
Mercedes-Benz Center if you use or have
used ethanol fuel (E85).Low outside temperatures
It is possible that the time required for the
starting procedure will significantly increase
at outside temperatures below 32 ‡ (0 †).
At low outside temperatures, Mercedes-Benz
recommends the use of an auxiliary heater.
For further information, contact an
authorized Mercedes-Benz Center.
Rough idling may also be experienced at low
outside temperatures until the engine is fully
warmed up.
Ethanol fuel (E85) is unsuitable for use when
outside temperatures fall below 14 ‡
(-10 †).
High outside temperatures
At outside temperatures above 95 ‡ (35 †),
the time required for the starting procedure
may increase and be accompanied by rough
idling following the start.
Fuel requirements
Use only premium-grade unleaded gasoline.
The octane number should be at least 91.
Details can be found on the gas pump. The
octane number is the average value of the
Research Octane Number (RON) and Motor
Octane Number (MON): (RON + MON) / 2,
also known as knock resistance.
Reformulated Gasoline (RFG) and/or
unleaded gasoline with additives can be used
if the concentration of the additives in the fuel
does 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 can be used.

Lubricant additives
! Do not mix any lubricant additives with
the engine oil. This could damage the
engine. Damage resulting from the use of
such lubricant additives in the engine oil is
not covered by the Mercedes-Benz Limited
Warranty.
Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Using the table below, make sure that the SAE
classification (viscosity) is sufficient for the
temperatures at which the vehicle is
operated. The low temperature
characteristics of engine oils can deteriorate
significantly, e.g. by aging, soot and fuel
deposits. It is therefore recommended that
you carry out oil changes regularly using an
approved engine oil with the appropriate SAE
classification.
Refrigerant of the air-conditioning
system
The air-conditioning system is filled with
R134a refrigerant and a special PAG
lubricant.
! Never use refrigerant R 12 (CFC) or
mineral lubricants. Otherwise, you could
damage the air-conditioning system.
Brake fluid
GWarning!
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
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 (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change
intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake
fluids can be obtained from any authorized
Mercedes-Benz Center.

Coolant
Important safety notes
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
The cooling system is filled with coolant at the
factory which contains antifreeze/corrosion
inhibitor that ensures protection down to
approximately -35 ‡ (-37 †).
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants and on
filling can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com . You
can also consult an authorized Mercedes-
Benz Center.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant in the pressurized system is
approximately 266 ‡ (130 †).
Your vehicle has a range of aluminum
components. Use of aluminum components
in the engine make it necessary to specifically
match the antifreeze/corrosion inhibitor in
these systems in order to protect the
aluminum parts. Using other antifreeze/
corrosion inhibitors without these
characteristics affects the service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and provide protection from
overheating. In the Service Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined by the
coolant type and the cooling system design.
The renewal interval in the Service Booklet is
only valid if the coolant is added or renewed
with Mercedes-Benz approved products.
Therefore, only use MB 326.0 antifreeze/
corrosion inhibitor or another Mercedes-Benz
approved product of the same specification.
Information on other Mercedes-Benz
approved products of the same specification
can be obtained at any authorized Mercedes-
Benz Center or on the Internet at
http://bevo.mercedes-benz.com .
The coolant is checked at every service date
at an authorized Mercedes-Benz Center.
The antifreeze/corrosion inhibitor
concentration in the cooling system should:
R be at least 50%. This will protect the cooling
system against freezing down to around
-35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ (-45 †); otherwise, heat will
not be dissipated as effectively.
If the coolant level is too low, MB 326.0
antifreeze/corrosion inhibitor should be
added. Have the cooling system checked for
leaks.
