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
Fuel
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.
! 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.
! Refuel only with commercially available
vehicle diesel fuel, ULTRA-LOW SULFUR
DIESEL with a sulfur content no greater
than 15 ppm. Fuels such as fatty acid
methyl ester FAME (bio-diesel fuels),
marine diesel, heating oil etc. may not be
used as a diesel fuel mixture.
Refuel with B5 bio-diesel only if it fulfills the
requirements listed under "Fuel quality". Service products

G
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.
