Load distribution
General notes
!
Excessive loads on individual points of the
cargo floor or on the load surface impair vehi-
cle handling characteristics and could cause
damage to the floor covering.
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
On Cargo Vans and Passenger Vans:
XAlways transport loads in the cargo compart-
ment.
XAlways place the load against the backrests of the rear bench seat.
XMove large and heavy loads as far towards the
front of the vehicle as possible against the
rear bench seat. Stow the load flush with the
rear bench seat.
XAlways additionally secure the load with suit-
able load-securing aids or tie downs.
Observe the following notes:
RDo not stack loads higher than the upper edge
of the backrests.
RTransport loads behind seats that are not
occupied.
RIf the rear bench seat is not occupied, insert
the seat belts crosswise into the buckle of the
opposite seat belt.
Securing loads
Important safety notes
GWARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction, brak- ing maneuvers or an accident:
Rthe cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
Rthe load may not be restrained.
This may cause the load to slip, tip over or be
tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads.
GWARNING
You may not transport anyone in the cargo
compartment or on the load surface. Never let more people ride in the vehicle than there are
seat belts available. Make sure everyone rid-
ing in the vehicle is correctly restrained with a
separate seat belt. Never use a seat belt for
more than one person at a time.
!Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the max-
imum loading capacity of the weakest cargo
tie-down point into account.
If you brake hard, for example, the forces act-
ing could be up to several times the weight
force of the load. Always use multiple cargo
tie-down points in order to distribute the force
absorption. Load the anchorages evenly.
Spread the load evenly between the cargo tie-
down points or tie-down rings.
Please also refer to the notes about qualified
specialist workshops (
Ypage 27).
Always observe the operating instructions or the
notes of the lashing strap manufacturer for the
operation of the lashing strap.
Information about the maximum loading capa-
city of the cargo tie-down points can be found in
the "Technical data" section (
Ypage 281).
As the driver, you are responsible for ensuring
that:
RThe load is secured against slipping, tipping,
rolling or falling off. This applies both in nor-
mal traffic conditions and if the vehicle must
swerve to avoid an obstacle, in the event of
full brake application and on poor road surfa-
ces.
RThe applicable requirements and guidelines
relating to load-securing practices must be
met.
If this is not the case, this may constitute a
punishable offense, depending on local legis-
lation and any ensuing consequences.

Maintenance
General notes
HEnvironmental note
Observe measures to protect the environ-
ment when working on the vehicle. You must
observe the legal requirements when dispos-
ing of service products, e.g. engine oil. This
also includes all components, e.g. filters,
which have come into contact with service
products. Any qualified specialist workshop
can provide information about this.
Dispose of empty containers, cleaning cloths
and care products in an environmentally

Z

responsible manner. Comply with the instruc-
tions for use of the care products.
Do not run the engine for longer than neces-
sary when the vehicle is stationary.
Before having maintenance and repairs per-
formed, it is essential to read the materials rela-
ted to the maintenance and repairs:
Rthe applicable sections of the technical doc-
umentation, e.g. the Operator's Manual and
workshop information.
Rregulations such as industrial safety regula-
tions and accident prevention regulations.
While working under the vehicle, you must
secure the vehicle on jack stands with sufficient load capacity.
Never use the jack as a substitute. The vehicle's
jack is intended only to raise the vehicle for a
short time when changing a wheel. It is not
suited for performing maintenance work under
the vehicle.
Please also refer to the notes about qualified
specialist workshops (
Ypage 27).
The scope and regularity of the inspection and
maintenance work primarily depend on the
often diverse operating conditions. Specialist
knowledge beyond the scope of this Operator's
Manual is required when carrying out testing
and maintenance work. This work should only be
carried out by trained staff.
The vehicle Maintenance Booklet describes the scope and frequency of maintenance work and
contains additional notes on the New Vehicle
Limited Warranty and on service products.
Maintenance services must be carried out in
accordance with the provisions and recommen-
dations in the Maintenance Booklet. Not doing
so could void the warranty claim and lead to
refusal of goodwill gestures after the manufac-
turer has submitted a damage report.
iObserve the notes on genuine Sprinter parts
(Ypage 29).
Service interval display
General notes
A service that is due is displayed in the service
interval display about 1 month in advance. A
message is then displayed while the vehicle is in motion or when the ignition is switched on.
iThe service interval display does not provide
information about the engine oil level. The
service interval display should therefore not
be confused with the 5engine oil level
display.
The service due date is displayed in days or
miles (kilometers), depending on the total dis-
tance driven.
The symbols or letters on the service display
show the type of service that is due.

222Maintenance
Maintenance and care

RDo not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
RReplace the tires after 6 years at the latest,
regardless of wear. This also applies to the
spare wheel.
Operation in winter
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Prior to the onset of winter, ensure that snow
chains are stowed in the vehicle (
Ypage 246).
Also observe the notes in the "Changing a
wheel" section (
Ypage 262).
Regularly check the vehicle and remove snow or ice when traveling in wintry conditions.
An accumulation of snow and ice, particularly
when frozen, caught in the area around the air
intake slots, moving parts, the axles and the
wheel arches may:
Rrestrict air intake
Rdamage vehicle parts
Rcause malfunctions by restricting the mobility
intended by the design (e.g. reduced possible
steering input).
If there is any damage, inform a qualified spe-
cialist workshop.
Driving with summer tires
At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehicle
to M+S tire. Using summer tires at very cold
temperatures could cause tears to form,
thereby damaging the tires permanently. We
cannot accept responsibility for this type of
damage.
M+S tires
GWARNING
Wheel and tire dimensions as well as the type of tire can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is mounted, driving characteristics may
be severely affected. There is a risk of an acci- dent.
In order to reduce risks:
Ryou should therefore adapt your driving
style and drive carefully.
Rnever mount more than one spare wheel
that differs from the wheel to be replaced.
Ronly use a spare wheel that differs from the
wheel to be replaced for a short time.
Rdo not deactivate ESP®.
Rhave a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type.
GWARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
Use winter tires or all-season tires at tempera-
tures below 45 ‡ (+7 †). Both types of tire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tires will allow driving safety systems
such as ABS and ESP
®to function optimally in
winter. These tires have been developed specif-
ically for driving in snow.
For safe driving, use M+S tire sof the same make
and tread pattern on all wheels.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
If you install M+S tires that have a lower maxi-
mum permissible speed than the maximum per-
missible speed of the vehicle, affix an appropri-
ate warning sign in the driver's field of vision.
You can obtain this at a qualified specialist work-
shop.

Once you have mounted the winter tires:
XCheck the tire pressure (Ypage 246).
XReactivate the tire pressure moni-
tor* (
Ypage 251).
Snow chains
GWARNING
If you drive too fast with snow chains moun-
ted, they may snap. As a result, you could
injure others and damage the vehicle. There is
a risk of an accident.
Observe the maximum permissible speed for
operation with snow chains.
When driving with snow chains installed, do not
exceed the maximum permissible speed of
30 mph (50 km/h). Observe the country-spe-
cific laws and regulations for operation with
snow chains.
!Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
Rwheel
Rwheel housing
Rwheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
!Vehicles with steel wheels: if you mount
snow chains on steel wheels, you may dam-
age the hub caps. Remove the hub caps from
the relevant wheels before mounting the
snow chains.
Snow chains increase traction on roads in wintry
conditions.
For reasons of safety we only recommend using snow chains or traction aids that are approved
for the Sprinter. The snow chains or traction aids
must be of class U or meet the SAE type U
specification. Information on snow chains is
available at any qualified specialist workshop.
When mounting snow chains, please bear the
following points in mind:
RSnow chains cannot be mounted on all
wheel/tire combinations. When mounting the snow chains, note the permissible tire and
snow chain dimensions.
RMount snow chains only in pairs and only to
the rear wheels. On vehicles with twin tires,
mount the snow chains to the outer wheels.
Observe the manufacturer's mounting
instructions.
RVehicles with all-wheel-drive:
snow chains
are not permitted on the front axle. There is
not sufficient space for commercially-availa-
ble snow chains. Information about snow
chains for all-wheel-drive vehicles can be
obtained from an authorized Sprinter Dealer.
ROnly use snow chains when the road is cov-
ered by a layer of snow. Remove the snow
chains as soon as possible when you come to
a road that is not snow-covered.
RThe use of snow chains may be restricted by
local regulations. Observe the appropriate
regulations before mounting snow chains.
RActivate all-wheel drive before driving off with
snow chains (Ypage 145).
RWhen driving with snow chains installed, do
not exceed the maximum permissible speed
of 30 mph (50 km/h).
RCheck the tension of the chains after a dis-
tance of approximately 0.5 miles (1.0 km).
You can deactivate ASR (
Ypage 54) when pull-
ing away with snow chains mounted. This allows
the wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).

Tire temper ature changes depending on the
ambient temperature, driving speed and tire
load. If the tire temperature changes by 18 ‡
(10 †), the tire pressure ch anges by approx

-
imately 10 kPa (0.1 bar/1.5 psi). Take this into
account when checking the pressure of warm
tires. Only correct the tire pressure if it is too low
for the current operating conditions. If you
check the tire pressure when the tires are warm,
it results in a higher value than when the tires
are cold. This is normal. Do not under any cir-
cumstances release the air in order to adjust the
pressure to the prescribed value for cold tires.
The tire pressure would otherwise be too low. Observe the recommended tire pressures for
cold tires:

Underinflated tires:
GWARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addition, they also suffer from excessive and/or irreg-
ular wear, which can severely impair the brak-
ing properties and the driving characteristics.
There is a risk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires can:
Rfail from being overheated
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
Overinflated tires
GWARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel.

damage to the fuel injection system, for
example.
B20 fuels with bio-diesel content
!Continuous use of B20 fuel can lead to fuel
filter clogging and injector deposits. This can
cause engine performance degradation.
Injector deposits can cause the engine oil
level to rise due to unburned fuel washing into
the oil pan. This can cause engine mechanical
damage.
To avoid damages and performance degrada-
tion:
RFill up with ULSD (B5 or less) whenever
possible.
RRegularly monitor your engine oil level if
you use B20 fuel on a regular basis.
RStrictly follow the oil change intervals quo-
ted in the instrument cluster and within
your maintenance booklet.
RUse only engine oils and filters approved for
use in your vehicle.
RIf you do not plan to drive your vehicle for
several weeks, fill your vehicle’s fuel tank in
advance with ULSD fuel.
For more information, consult the gas station
staff. The fatty acid methyl ester B5 or B20 label on the fuel pump must clearly state that the
standard for ULSD is complied with. If the mark-
ing does not make this clear, do not refuel from that pump.
Do not refuel with any fuels that have not been
approved for your vehicle.

Information on fuel consumption
HEnvironmental note
CO
2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO
2emissions are directly related to
fuel consumption and therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it serv-
iced regularly.
Fuel consumption depends on:
Rthe vehicle version
Rthe style of driving
Rthe operating conditions
Rthe type or quality of the fuel used
The vehicle will use more fuel than usual in the
following situations:
Rat very low outside temperatures
Rin city traffic
Rduring short journeys
Ron mountainous terrain
Rwhen towing a trailer
To keep fuel consumption low, observe the
advice in the "Protection of the environment"
section (
Ypage 25).
The following components of the different vehi-
cle versions influence fuel consumption:
Rtire sizes, tire tread, tire pressure, tire condi-
tion
Rbody
Rtransmission ratios for the drive assemblies
Radditional equipment (e.g. air-conditioning
system, auxiliary heating system)
For these reasons, the actual consumption fig-
ures for your vehicle may deviate from the con-
sumption figures determined according to EU
Directive 80/1268/EEC.
Data concerning fuel consumption are recorded in the on-board computer; use the steering
wheel buttons to call up the Trip computer
menu (
Ypage 171).
Diesel Exhaust Fluid (DEF)
General notes
HEnvironmental note
Dispose of DEF in an environmentally respon-
sible manner.
Service products and capacities275
Technical data
Z

When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape.
Ammonia vapors have a pungent smell and pri-
marily cause irritation of the:
Rskin
Rmucous membranes
Reyes
You may experience a burning sensation in your
eyes, nose and throat, as well as coughing and
watering of the eyes.
Do not inhale ammonia vapors. Avoid contact
with DEF.
Do not allow DEF to come into direct contact
with your skin; it is hazardous to your health.
Rinse any affected areas off with plenty of clean water. Consult a doctor if necessary.
If DEF heats up, e.g. in direct sunlight, in the DEF
supply reservoir for some time to over 122 ‡
(50 †), ammonia vapor will develop.
To conform to emission regulations, you must
operate the vehicle with DEF and refill the supply
regularly. The engine management recognizes
attempts to operate the vehicle without DEF,
with thinned DEF or with another reducing
agent. After previous warning messages, the
engine management then prevents a further
engine start.
When the number of remaining engine starts is 0
the engine management prevents the vehicle
from being driven at a speed exceeding 5 mph
(8 km/h). The multifunction display shows the
Idle Mode
message.
DEF consumption
DEF consumption depends on operational and
driving conditions and it is not necessary to wait
until the next scheduled service to replenish the
fluid. Fluid should be added regularly to the DEF
supply reservoir during vehicle operation or, at
the latest, after receiving the first warning mes-
sage via the on-board computer.
Low ambient temperatures
DEF freezes at a temperature of approximately
12‡(Ò11 †). The vehicle is equipped with a DEF
preheating system at the factory. Winter oper-
ation is therefore also guaranteed at tempera-
tures under 12 ‡ (Ò11 †).
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF. Drive for at least 20 minutes (heating phase in
the tank activated) and then stop the vehicle
for at least 30 seconds. The level is then
shown correctly.
Additives
!Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise, the
exhaust gas aftertreatment may be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage that arises through the use of addi-
tives or tap water will invalidate the New Vehi-
cle Limited Warranty.
Storage
!Containers made of aluminum, copper, cop-
per alloys as well as unalloyed or galvanized
steel are not suitable for storing DEF. If stored
in these types of containers, DEF could cause
constituents of these metals to dissolve and

Purity
!Impurities in DEF (e.g. caused by other ser-
vice products, cleaning agents, dust, etc.)
result in increased emissions, malfunctions,
catalytic converter damage or engine dam-
age.
The purity of DEF is essential to prevent mal-
functions in the exhaust gas aftertreatment.
If DEF is pumped out of the DEF tank, e.g. during
repair work, the same liquid must not be used to
refill the tank. Its purity is no longer guaranteed.
