Refueling
G
Warning
Fuel is highly flammable. Fire, naked flames
and smoking as well as the use of auxiliary
heaters (sparks) are therefore prohibited
when handling fuel.
Switch off the
engine and the auxiliary heating
before refueling. G
Warning
Avoid any contact with fuels.
You can damage your health if your skin
comes into direct contact with fuel or if you
inhale fuel vapors.
0040Environmental note
If fuels are handled improperly, they pose a
danger to persons and the environment. Do
not allow fuels

to run into the sewage system,
the surface waters, the ground water or into
the ground.
! Filter the fuel

before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel
system due to contaminated fuel. G
Warning
Do not use gasoline to refuel vehicles with a
diesel engine. Never

mix diesel with gasoline.
This causes damage to the fuel system and
engine and could result in the vehicle catching
fire.
! Do not use gasoline to refuel vehicles with
a diesel engine. Even small amounts of
gasoline will cause damage to the fuel
system and engine. Damage resulting from
adding gasoline is not covered by the New
Vehicle Limited Warranty. !
If the wrong fuel has been added by
mistake, do not switch on the ignition. If
you do, the fuel could enter the fuel lines.
The tank and the fuel lines must then be
drained. Inform a qualified specialist
workshop and have the tank and the fuel
lines drained completely.
The fuel filler

flap is beside the front left-hand
door when viewed in the direction of travel. It
is only possible to open the fuel filler flap
when the front door is open. X
Remove the key from the ignition lock.
X Switch off the auxiliary heating system
(Y page 104).
X Open the front left-hand door first, and then
the fuel filler flap.
X Close all vehicle doors to prevent fuel
vapors from entering the vehicle.
X Turn tank filler cap 0047 counter-clockwise,
remove it and let it hang from retaining
strap 0046.
X Only fill the tank until the pump nozzle
switches off.
X Replace tank filler cap 0047 and turn
clockwise.
You will
hear

a click when the fuel filler cap
is closed fully.
X Open the front left-hand door first, and then
close the filler flap.
You will find information about fuel in the
"Service products" section (Y page 153). 142
Refueling
Operation

Verify compliance with weight limitations on
a weighbridge.
Trailer power supply
Your vehicle may be equipped with various
electrical fittings for trailer towing.
Depending on your trailer, you may need an
adapter to allow your trailer to be connected
to the vehicle. Information about your
vehicle's electrical equipment is available
from any authorized Sprinter Dealer.
!
Faulty wiring of the connector plug could
in certain circumstances cause other
electronic systems to
malfunction. For this
reason, we recommend having the wiring
of the connector plug performed at an
authorized Sprinter Dealer. Operation in winter
General notes
Have your vehicle winterized at a qualified
specialist workshop, e.g. an authorized
Sprinter Dealer, at the onset of winter.
This service includes the following:
R oil change, if the engine oil currently used
does not have adequate low temperature
characteristics or if these are no longer
sufficient due to aging
R the antifreeze/anticorrosion
concentration in the coolant is checked.
R the addition of a concentrated cleaning
agent to the water in the windshield
washer/headlamp cleaning system
R battery check
R a tire change
Prior to the

onset of winter, ensure that snow
chains are available in the vehicle.
Do not cover the surface of the radiator or the
radiator grill, even in winter. Doing so could
cause the engine diagnostics to record false
or incorrect data. Recording of engine
diagnostic data is legally prescribed and must therefore be correct, clear and
comprehensible at all times.
You
will find

information about diesel fuel for
use at low outside temperatures in the
"Operation" section ( Y page 154).
Please also observe the information about
winter driving (Y page 111).
You will find information about winter tires
and about driving with snow chains in the
"Wheel and tires" section (Y page 153). Service products

Warning
The operating safety of the vehicle can be compromised if maintenance work is carried out
incorrectly. In particular, work that is carried out incorrectly on the heater jeopardizes its
operating safety. This

could cause you to lose control of the vehicle and cause an accident. The
safety systems may also not be able to protect you or others as they are designed to do.
Always have maintenance work carried out at a qualified specialist workshop. The qualified
specialist workshop must have the necessary specialist knowledge and tools to carry out the
work required. We recommend that you use an authorized Sprinter Dealer for this purpose. In
particular, work relevant to safety or on safety-related systems must be carried out at a qualified
specialist workshop.
