Mercedes Benz 2004 c 320 Manual De Usuario

A major concern among engine 
manufacturers is carbon build-up caused 
by gasoline. Mercedes-Benz recommends 
only the use of quality gasoline containing 
additives that prevent the build up of 
carbon deposits.

After an extended period of using fuels 
without such additives, carbon deposits 
can build up especially on the intake valves 
and in the combustion area, leading to 
engine performance problems such as:

앫

Warm-up hesitation

앫

Unstable idle

앫

Knocking/pinging

앫

Misfire

앫

Power loss

Do not blend any specific fuel additives 
with fuel. This only results in unnecessary 
cost and may be harmful to engine 
operation.

Damage or malfunctions resulting from 
poor fuel quality or from blending specific 
fuel additives are not covered by the 
Mercedes-Benz Limited Warranty.

Flexible Fuel Vehicles are identified by a 
label reading Premium gasoline or E85 
only! on fuel filler flap.

These vehicles are designed to operate on 
premium unleaded gasoline or Ethanol 
fuel (E85), or on any mixture of these two.

Ethanol fuel (E85) is a mixture of 
approximately 85% Ethanol and 15% 
unleaded gasoline.

For best performance and driveability it is 
recommended to use either one or the 
other fuel. A refueling pattern that 
alternates between the two different fuels 
should be avoided if possible.

G

Ethanol fuel (E85) and its fumes are highly 
flammable, poisonous and burn easily. Etha-
nol fuel can cause serious injuries if ignited 
or if you come into contact with it or inhale 
fumes of it. Avoid inhalation of Ethanol 
fumes and skin contact with Ethanol. Extin-
guish all open flames before fueling. Never 
smoke or create sparks close to Ethanol.
