Possible cause
Suggested solution
?
The yellow “CHECK ENGINE”
malfunction indicator lamp
comes on while driving.
There is a malfunction in:
The fuel management system
The ignition system
The emission control system
Systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.
Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located in the front left
area of the footwell next to the
parking brake pedal.
The fuel cap is not closed tight.
Check the fuel cap.
Your gas tank is empty.
After refuelling start the engine three
or four times in succession.
The limp-home mode is canceled. You do
not need to have your vehicle checked.

355 Technical data
Fuels, coolants, lubricants, etc.
When switching fuels, make sure:
Fuel level is below half full.
Fuel level is above reserve (fuel 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 (Canada only) is
recommended (see your authorized
Mercedes-Benz Center for further
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.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 Mercedes-Benz Center
if you use or have used E85 fuel when your
vehicle is delivered for maintenance or
repairs.
!E85 fuel is unsuitable for use when
ambient temperatures fall below 14°F
(-10°C).
iUse of E85 may reduce your driving
range.
