indicator lamp lights up.
To this end, have the fuel filter with wa-
ter separator drained at an authorized
Sprinter Dealer which has the necessary
specialist knowledge and tools to carry
out the work required.The fuel filter with water separator is in
the engine compartment.

\1
Drain the fuel filter again if the
/
indicator lamp remains lit.If the fuel tank on a vehicle with diesel
engine has been run dry, there is a pos-
sibility that the engine may not start im-
mediately after refueling because air
may remain in the fuel system.
After refueling:
\1
Switch on the ignition for approxi-
mately 10 seconds.
\1
Start the engine repeatedly for no
more than 60 seconds until it runs
smoothly.
If the engine does not start:
\1
Wait approximately 2 minutes.
\1
Then start the engine repeatedly
again for no more than 60 seconds
until it runs smoothly.
If this attempt also fails, do not continue
to start the engine. Consult an autho-
rized Sprinter Dealer.
Environmental note
H
Have the drained liquid disposed of at an
authorized Sprinter Dealer.!
CAUTION
If the
/
indicator lamp remains
lit even after draining for the second
time, have the cause checked imme-
diately at an authorized Sprinter
Dealer.
Bleeding the fuel systemiToo many attempts to start the en-
gine could drain the battery.

Service products are tested for suitabili-
ty in our assemblies. Approved service
products meet the highest quality stan-
dards and are listed in the
Mercedes-
Benz Specifications for Service Pro-
ducts
. For this reason, only use service
products that have been approved for
your vehicle. This is an important condi-
tion for warranty claims to be upheld. In-formation about approved service
products is available from all authorized
Sprinter Dealers.
You will find details about windshield

It is neither necessary nor permissible to
mix special additives with approved ser-
vice products (except for approved fuel
additives). Therefore, special additives
must not be mixed with fuels or lubri-
cants. The properties of the service
products could be adversely affected by
special additives and result in damage to
the assemblies.The vehicle operator is responsible at all
times for any use of special additives.
The use of special additives may result in
a limitation or an invalidation of your
warranty entitlement.

Fuels for gasoline engines
Premium unleaded gasoline
FuelsWarning
G
Gasoline is highly flammable and poison-
ous. It burns violently and can cause seri-
ous injury. Whenever you are around
gasoline, avoid inhaling fumes and skin
contact, extinguish all smoking materials.
Never allow sparks, flame or smoking ma-
terials near gasoline! Direct skin contact
with fuels and the inhalation of fuel va-
pors are damaging to health.
Switch off the engine before refueling.
!
CAUTION
If you are refueling the vehicle from
drums or canisters, you should filter
the fuel before adding it to the tank.
This will prevent malfunctions in the
fuel system caused by contaminated
fuel.
!
CAUTION
To maintain the engine’s durability
and performance, premium unleaded
gasoline must be used. If premium
unleaded is not available and low oc-
tane fuel is used, follow these pre-
cautions:
Have the fuel tank only partially filled
with unleaded regular and fill up with
premium unleaded as soon as possi-
ble.
Avoid full throttle driving and abrupt
acceleration.

Fuel requirementsOnly use premium unleaded fuel:\4
The octane number (posted at the
pump) must be 91 min. It is an aver-
age of both the Research (R) octane
number and the Motor (M) octane
number: (R+M) / 2). This is also
known as the ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygen-
ates such as ethanol, IPA, IBA and TBA
can be used provided the ratio of any
one of these oxygenates to gasoline
does not exceed 10%; MTBE not to
exceed 15%.The ratio of methanol to gasoline must
not exceed 3% plus additional cosol-
vents.
Using mixtures of ethanol and methanol
is not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.
These blends must also meet all other
fuel requirements, such as resistance to
spark knock, boiling range, vapor pres-
sure, etc. Do not exceed an engine speed
of 3000 rpm if the vehicle is loaded
with a light load, such as two persons
and no cargo.
Do not exceed
2/3 of maximum ac-
celerator pedal position if the vehicle
is fully loaded or operating in moun-
tainous terrain.

Fuels for diesel engines Fuel requirements
Only use commercially available vehicu-
lar ULTRA-LOW SULFUR HIGHWAY DIE-
SEL FUEL (15 ppm SULFUR MAXIMUM).
Chrysler Vans LLC USA now approves
the use of B5 bio diesel (standard diesel
with a maximum of up to 5% Bio diesel
content) in the Sprinter vehicle CRD die-
sel engine.
Information on diesel quality can
normally be found on the fuel pump.
!
CAUTION
The following may lead to increased
wear or engine damage:
\4
Using gasoline that does not
meet the specifications men-
tioned above
\4
The use of non-approved special
additives
!
CAUTION
Marine diesel fuel, Bio diesel fuel,
heating oil or the like must not be
used.
Do not blend diesel fuel with marine
diesel fuel, Bio diesel fuel or heating
oil. The use of such non-approved fu-
els or blending diesel fuel may result
in malfunction or cause engine dam-
age. Damage or malfunctions result-
ing from poor fuel quality or from
blending specific fuel additives are
not covered by the Sprinter warranty.
