Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Loading guidelines
Important safety notes
GWARNING
As a result of improperly placed or unevenly
distributed loads, the center of gravity of the
load being transported may be too high or too
far back. This can significantly impair handling
as well as steering and braking characteris-
tics. There is a risk of an accident.
Always make sure that the center of gravity of
the load is:
Rbetween the axles
and
Ras low as possible, near the rear axle.
GWARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be thrown
about, striking vehicle occupants. This also
applies to:
Rluggage or loads
Ra rear bench seat which has been removed
and is being transported in the vehicle in an
exceptional case.
There is a risk of injury, particularly in the
event of braking maneuvers or abrupt
changes in direction.
Always stow objects in such a way that they
cannot be tossed about. Before traveling,
secure objects, luggage or loads to prevent
them slipping or tipping over. If you remove a
rear bench seat, it is advisable to store it out- side the vehicle.
GWARNING
When the permissible wheel loads, axle loads
and/or the maximum permissible gross vehi-
cle weight are exceeded, driving safety is
compromised. The handling as well as steer-
ing and braking characteristics may be signif-
icantly impaired. Overloaded tires may over-
heat, causing them to burst. There is a risk of
an accident.
When transporting a load, always observe the
permissible wheel loads, axle loads and the
maximum permissible gross vehicle weight
for the vehicle (including occupants).
GWARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character-
istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.
There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
!If you are using a roof carrier, observe the
maximum roof load and maximum roof carrier
load.
You will find information about the maximum
roof load in the "Technical data" section
(
Ypage 287) and information about roof carri-
ers in the "Carrier systems" section
(
Ypage 217).
RDo not stack luggage or loads higher than the
backrests.
RStow objects preferably in the cargo com-
partment.
RWhen transporting luggage, always use the
cargo tie-down rings and a parcel net, if pres-
ent.
RUse cargo tie-down rings and fasteners which
are suitable for the weight and size of the
load.
Always observe the operating instructions of the respective manufacturer when using suitable
load securing aids or tie downs. In particular, the
information on service life.
Loading guidelines213

!Make sure that:
Rthe side windows and the roof are com-
pletely closed
Rthe climate control blower is switched off
Rthe windshield wiper switch is at position0
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehicle
in an automatic car wash.
After putting the vehicle through an automatic
car wash, wipe off wax from:
Rthe rear view camera lens (Ypage 237)
Rthe windshield
Rthe windshield wiper blades
This will prevent smears and reduce wiping
noises caused by residue on the windshield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements of the country
you are currently in when washing by hand.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse a soft car sponge.
XUse a mild cleaning agent, e.g. a car shampoo
approved for use with Sprinter vehicles.
XThoroughly hose down the vehicle with a gen-
tle jet of water.
XDo not point the water jet directly towards the
air inlets.
XUse plenty of water and rinse out the sponge
frequently.
XRinse the vehicle with clean water and dry
thoroughly with a chamois.
XDo not let the cleaning agents dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Under no circumstances use power washers
in the vehicle interior. The pressurized water
and associated spray produced by the power washer could cause extensive damage to the
vehicle.
!Observe the minimum distance to be main-
tained between the nozzle of the high-pres-
sure cleaner and the object to be cleaned:
Rapproximately 2.2 ft(70 cm) when using
round-jet nozzles
Rapproximately 1 ft (30 cm) when using 25°
flat-spray jets and concentrated-power jets
Keep the water jet moving while cleaning. To
avoid causing damage, do not point the water jet directly at:
Rdoor joints
Rbrake hoses
Relectrical components
Relectrical connections
Rseals
Rdrive train, especially not at the intermedi-
ate bearing of the propeller shaft
Rrear view camera
Keep a minimum distance of 1.6 ft(50 cm).
Cleaning the engine
!Water must not enter intake or ventilation
openings. When cleaning with high pressure
water or steam cleaners, the spray must not
be aimed directly at electrical components or
the terminals of electrical lines.
Preserve the engine after the engine has been
cleaned. Protect the belt drive system from
exposure to the preservative agent.
Also observe the information under "Power
washers" (
Ypage 235).

Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
XRemove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
XSoak insect remains with insect remover and
rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse off
the treated areas afterwards.
XRemove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
Cleaning the windows
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
!Do not fold the windshield wipers away from
the windshield unless the hood is closed. Oth-
erwise, you could damage the hood.
!Hold the wiper arm securely when folding
back. The windshield could be damaged if the
wiper arm smacks against it suddenly.
!Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There
is otherwise a risk of damaging the windows. Before cleaning the windshield
XTurn the key to position
0in the ignition lock
or remove it.
XFold the windshield wiper arms away from the
windshield until you feel them engage.
Before switching the ignition on again, fold
the windshield wipers back into position.
Cleaning the windows
XClean the inside and outside of the windows
with a damp cloth and a cleaning agent that is
recommended and approved for Sprinter
vehicles.
Exterior
Cleaning the wheels
!Do not use any acidic or alkaline cleaning
agents. They can cause corrosion on the
wheel bolts (wheel nuts) or the retainer
springs for the wheel-balancing weights.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after cleaning.
Braking heats the brake discs and the brake
pads/linings, thus drying them. The vehicle
can then be parked.
If you clean the wheels with a power washer,
observe the safety notes for the power washer
(
Ypage 235). You could otherwise damage the
tires.
Cleaning the wiper blades
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or

Important safety notes
GWarning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel, or
consult a qualified specialist workshop.
GWARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tires with those
that fulfill the specifications of the original
part.
When replacing wheels, make sure to use the
correct:
Rdesignation
Rmodel
When replacing tires, make sure to use the
correct:
Rdesignation
Rmanufacturer
Rmodel
Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor-
rectly can impair operating safety. Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Contact an authorized Sprinter dealer if you
require information on tested and recommen-
ded wheels and tires for summer and winter
driving. Advice on purchasing and caring for
tires is also available there.
Information on tire and wheel dimensions and
types as well as the recommended tire pressure
for your vehicle can be found in the "Tire pres-
sure" section (
Ypage 257).
This data can also be found on the Tire and
Loading Information placard on the B-pillar.
Modifications to the brake system or wheels are
not permitted. The use of a spacer and brake
dust shields is not permitted. This invalidates
the general operating permit for the vehicle.
iFurther information on wheels and tires can
be obtained at any qualified specialist work-
shop.
Operation
Information for a journey
If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary
(
Ypage 251).
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tires are damaged. If you suspect that
a tire is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tires for damage. Hidden
tire damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tires and wheels checked at a
qualified specialist workshop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at a sharp angle. Otherwise, the
tires, particularly the sidewalls, can get dam-
aged.
248Operation
Wheels and tires

Regular wheel and tire checks
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two weeks,
as well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of tire
pressure. Pay particular attention to damage
such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 249). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect the valve against dirt and moisture. Do not install
anything onto the valve other than the standard
valve cap or other valve caps approved for your vehicle by dealers listed on the inside of the
front cover. Do not install any other valve caps
or systems, e.g. tire pressure monitor systems.
Regularly check the pressure of all the tires,
particularly prior to long trips. Adjust the tire
pressure if ne
cessary (Ypage 251).
The service life of tires depends on various fac-
tors, including the following:
RDriving style
RTire pressure
RMileage
Tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Bar marking :for tread wear is integrated into
the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth is
approximately áin. (1.6 mm). If this is the
case, the tire is so worn that it must be replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.
ROnly mount tires of the correct size onto the
wheels.
RBreak in new tires at moderate speeds for the first 65 miles (100 km).
Operation249
Wheels and tires
Z

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 six 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 251).
Also observe the notes in the "Changing a
wheel" section (
Ypage 267).
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.
250Operation in winter
Wheels and tires

Once you have mounted the winter tires:
XCheck the tire pressure (Ypage 251).
XReactivate the tire pressure moni-
tor* (
Ypage 256).
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 147).
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 55) 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).
