Warning!
G
In the event a malfunction of the SRS is
indicated as outlined above, the SRS may
not be operational.
For your safety, we strongly recommend
that you visit an authorized Mercedes-Benz
Center immediately to have the system
checked; otherwise the SRS may not be
activated when needed in an accident,
which could result in serious or fatal injury,
or it might deploy unexpectedly and unnec-
essarily which could result in an accident
and/or injury to you or to others.

Flexible Fuel Vehicles
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 approxi-
mately 85% Ethanol and 15% unleaded
gasoline.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.
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
further information). Rough idling may also
be experienced at such temperatures
before the engine is fully warmed up.
Warning!
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.
!E85 fuel is unsuitable for use when am-
bient temperatures fall below 14°F
(-10°C).
