272 Operation
At the gas station
Turn the engine off by turning the
SmartKey to position0.
Remove the SmartKey from the starter
switch.
Open the fuel filler flap by pushing at
the point indicated by arrow1.
The fuel filler flap springs open.
Turn fuel cap counterclockwise and
hold on to it until possible pressure is
released.
Take off cap and set it in direction of
arrow2 in the recess on the fuel filler
flap.
To prevent fuel vapors from escaping
into open air, fully insert filler nozzle
unit.
Only fill your tank until the filler nozzle
unit cuts out – do not top up or
overfill.
Replace fuel cap by turning it clockwise
until it audibly engages.
Close fuel filler flap.
iOnly use premium unleaded gasoline with a
minimum Posted Octane Rating of 91 (average
of 96 RON / 86 MON). Information on gasoline
quality can normally be found on the fuel pump.
C 230/C 230 Sport:
Flexible Fuel Vehicles are identified by a label
reading Premium gasoline or E85 only! on the
fuel filler flap.
For more information on gasoline or E85, see
“Premium unleaded gasoline” (
page 413) or
the Factory Approved Service Products pam-
phlet.
Warning!G
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel
pump nozzle, which could cause personal
injury.
iMake sure to close the fuel filler flap before
locking your vehicle as the flap locking pin
prevents closing after you have locked the
vehicle.
iLeaving the engine running and the fuel cap
open can cause the yellow fuel tank reserve
warning lamp to flash and theú malfunction
indicator lamp (USA only) or the± malfunc-
tion indicator lamp (Canada only) to illuminate.

Switching fuels
For best performance and driveability it is
recommended to use either one or the oth-
er fuel. A refueling pattern that alternates
between the two different fuels should be
avoided if possible.
When switching fuels, make sure:

Fuel level is below half full.

Fuel level is above reserve (reserve
warning lamp is not lit).

Amount of added fuel is more than
5 gallons (20 liters).

Ignition is off during refill.

Immediately after refueling engine is
started and operated for at least five
minutes.
These precautions and recommendations
are supposed to 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, adding
more gasoline (at least 3 gallons
[12 liters]) to the fuel may improve the
engine behavior.
Cruising range
E85 fuel contains less energy per gallon
than gasoline. To ensure that engine per-
formance with Ethanol fuel 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 E85 compared to
gasoline operation.
Maintenance
Please inform your authorized
Mercedes-Benz Center if you use or have
used E85 fuel when your vehicle is deliv-
ered for maintenance or repairs.Cold weather performance
It is possible that starting times will signif-
icantly increase at temperatures below
32°F (0°C). At low temperatures the use
of a block heater is recommended (see an
authorized Mercedes-Benz Center for fur-
ther information). Rough idling may also be
experienced at such temperatures before
the engine is fully warmed up.
Hot weather performance
At ambient temperatures above 95°F
(35°C) start times may increase and be
accompanied by a rough idle following the
start.iUse of E85 may reduce your driving range.
!E85 fuel is unsuitable for use when ambient
temperatures fall below 14°F (-10°C).
