284 Operation
At the gas station
Open fuel filler flap1 by pushing at
the point indicated by the arrow.
The fuel filler flap springs open.
Turn fuel cap2 counterclockwise and
hold on to it until possible pressure is
released.
Take off fuel cap2 and place it into
holder3 located on the inside of 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 off or over-
fill.
Replace fuel cap by turning it clockwise
until it audibly engages.
Close the fuel filler flap.
Warning!G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas-
oline fuel discharge. This could cause the
gasoline fuel to spray back out when remov-
ing 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 pre-
vents 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 the malfunction indi-
cator lampú(USA only) or the malfunction
indicator lamp±(Canada only) to illuminate.
See also “Practical hints” section (
page 348).
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.
Please contact gas station personnel in case
labels on the pump cannot be found.
For more information on gasoline, see “Premium
unleaded gasoline” (
page 451), see “Fuel re-
quirements” (
page 451), and the Factory Ap-
proved Service Products pamphlet (USA only) or
contact an authorized Mercedes-Benz Center.
