! Do not fill the tank with gasoline. Do not
blend diesel fuel with gasoline or kerosene.
The fuel system and engine will otherwise
be damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
For further information on diesel fuel pump
labeling, contact an authorized Mercedes-
Benz Center or visit

Biodiesel (FAME = Fatty Acid Methyl
Ester) containing fuels
Mercedes-Benz USA approves the use of B5
(standard ULSD which may contain a
maximum of 5% biodiesel) in all Common-rail
injection (CDI) and BlueTEC diesel engines.
Diesel fuels containing a higher percentage of
biodiesel, e.g. B20, as well as straight
biodiesel may cause severe damage to your
engine/fuel system and are not approved.
Please ask your service station personnel for
further information. If the B5 biodiesel blend
is not sufficiently labeled to clearly indicate
that it meets the ULSD standard, please do
not use it.
The Mercedes-Benz Limited Warranty does
not cover damages caused by the use of fuels
not meeting Mercedes-Benz approved fuel
standards.
Gasoline additives (gasoline engine)
A major concern among engine
manufacturers is carbon build-up caused by
gasoline. Mercedes-Benz recommends only
the use of quality gasoline containing
additives that prevent the build-up of carbon
deposits.
After an extended period of using fuels
without such additives carbon deposits can
build up, especially on the intake valves and
in the combustion area, leading to engine
performance problems such as:
R
Warm-up hesitation
R
Unstable idle
R Knocking/pinging
R Misfire
R Power loss
In areas where carbon deposits may be
encountered due to lack of availability of
gasoline which contains these additives, the
use of Mercedes-Benz approved additives is
recommended.
Contact an authorized Mercedes-Benz Center
or visit
www.mbusa.com (USA only) for a
listing of approved products. Follow
directions on the product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and may
be harmful to the engine operation.
! Damage or malfunction resulting from
poor fuel quality or from blending additional
fuel additives other than those tested and
approved by us for use on Mercedes-Benz
vehicles are not covered by the Mercedes-
Benz Limited Warranty or by any pre-owned
or Extended Limited Warranties.
AdBlue ®
AdBlue ® is a non-flammable, non-toxic,
colorless and odorless, water-soluble liquid.
! Only use AdBlue ® complying with
ISO 22241. Do not blend with additives.
! Rinse surfaces that have come into
contact with AdBlue ® , or remove AdBlue ®
with a moist cloth and cold water
immediately. If AdBlue
® has crystallized
already, use cold water and a sponge.
AdBlue
® residues will crystallize and soil
the affected surfaces.
High ambient temperatures
If AdBlue ® in the reservoir heats up to above
122‡ (50†) for a long period of time, for
example due to direct sunlight, ammonia gas
