2012 MERCEDES-BENZ SPRINTER radiator

Modifying the engine power output
Having the engine power output of your
vehicle increased by tampering with the
electronic engine management system will
invalidate the vehicle's general operating
permit and insurance coverage, as well as
your New Vehicle Limited Warranty and
warranty entitlement.
Modifications to the output of the engine
must be reported to the insurance provider
and require the vehicle to be recertified. The
tires, chassis, brake and cooling systems
must be adapted to the increased engine
power output.
Tampering with the electronic engine
management system modifies emission
values and it
will not be possible to guarantee
the operating safety of the engine in every
case. Increases in performance may lead to
malfunctions and consequential damage to
other assemblies.
If you sell the vehicle, failing to inform the
buyer of the modified engine power output
could constitute an offense punishable by
law, depending on the country concerned. Diesel particle filter
! If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning
function for the diesel particle filter. As a
result, fuel may accumulate in the engine
oil and cause engine failure.
Therefore, if you mainly drive short
distances, you should

drive on a highway or
on rural roads for 20 minutes every
310 miles (500 km). This ensures sufficient
regeneration of the diesel particle filter. Vehicle alterations
We recommend the use of genuine Sprinter
parts and conversion parts as well as accessories that have been expressly
approved for your vehicle model.
These parts have been subjected to special
tests in order to determine their safety,
reliability and suitability.
!
For safety reasons, have add-on
equipment prepared and installed
according to the

Sprinter body/equipment
mounting directives in force. These body/
equipment mounting directives guarantee
that the chassis and add-on equipment
form a cohesive whole and that the highest
possible level of operating and driving
safety is reached.
We recommend for safety reasons that:
R you carry out no other modifications to
the vehicle.
R you obtain the agreement of the
distributor named on the inside of the
front cover for any deviations from the
approved body/equipment mounting
directives.
Approval by official testing centers or
permission given by authorities do not
eliminate safety risks.
! The wooden or plastic cargo area floor
fitted at the factory is an integral
component of the vehicle structure. The
vehicle body could be damaged if you have
the load area floor removed. This then
affects the securing of loads and the
maximum loading capacity of the lashing
points is no longer guaranteed.
Therefore, do not have the load area floor
removed.
Even seemingly small changes to the vehicle,
such as attaching a radiator cover for winter
driving or as protection against insects, are
not allowed. These could cause the engine
diagnostics to register incorrect data. The
recording of engine diagnostic data is a legal
requirement, and must always be verifiable
and accurate. 18
Introduction

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

Cleaning and care
General notes
Regular care serves to maintain the value of
your vehicle.
It is advisable to use care products from the
distributor named on the inside of the front
cover. They are designed specifically for
Sprinters and represent the state of the art.
These care products are available from any
authorized Sprinter Dealer.
Do not cover

the surface of the radiator or the
radiator grill, e.g. with a protective screen.
Doing so could cause the engine diagnostics
to record false or incorrect data. The
recording of specific engine diagnostic data
is legally prescribed and must therefore be
correct, clear and comprehensible at all
times. G
Warning
Always keep care products sealed and out of
the reach of children.
Always follow the instructions for use of the
care products.
Do not use fuel as a cleaning agent. Fuel is
highly flammable and constitutes a health
hazard.
