Technical data
Fuels, coolants, lubricants, etc.
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 be-
fore the engine has fully adapted to the dif-
ferent 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 en-
gine 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
your authorized Mercedes-Benz Center for
further information). Rough idling may also
be experienced at such temperatures be-
fore the engine is fully warmed up.
Hot weather performance
At ambient temperatures above 95°F
(35°C) start times may increase and be ac-
companied by a rough idle following the
start.
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 gas-
oline operation.
Maintenance
Please inform your Mercedes-Benz Center
if you use or have used E85 fuel when your
vehicle is delivered for maintenance or re-
pairs.
!E85 fuel is unsuitable for use when am-
bient temperatures fall below 14°F
(-10°C).
iUse of E85 may reduce your driving
range.
