Problem
Possible cause
Suggested solution
The yellow fuel tank reserve warning lamp in the
fuel gauge comes on while driving.
The fuel level has gone below the reserve
mark.

Refuel at the next gas station
(page 275).

for a brief period after starting the
engine.
The telltale reminds you to fasten seat
belts.

Fasten your seat belt.

1
The red SRS indicator lamp comes on
while driving.
There is a malfunction in the restraint
systems. The air bags or emergency ten-
sioning device (ETDs) could deploy unex-
pectedly or fail to activate in an accident.

Drive with added caution to the
nearest authorized Mercedes-Benz
Center.
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 autho-
rized 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 unnecessarily which could result in an
accident and/or injury to you or to others.

Switching fuels
For best performance and driveability it is
recommended to use either one or the
other 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 (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 an 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 make sure that engine
performance 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.
