When you have mounted M+S tires:
X
Check the tire pressure (Y page 255).
X Restart the tire pressure monitor
(Y page 258). G
Warning
If you use your spare wheel when M+S tires
are fitted on the other wheels, be aware that
the difference in
tire characteristics may very
well impair turning stability and that overall
driving stability may be reduced. Adapt your
driving style accordingly.
Have the spare wheel replaced by a regular
road wheel with an M+S tire at the nearest
authorized Sprinter Dealer. Snow chains
Snow chains increase traction on roads in
wintry conditions.
We recommend, for safety reasons, that you
only use class

U snow chains or traction aids
that conform to the SAE type U specification
and are approved for Sprinters. You can
obtain information about snow chains from
any authorized Sprinter Dealer.
R Only use snow chains when the road is
covered by a layer of snow. Do not exceed
the maximum permissible speed of 30 mph
(50 km/h). Remove the snow chains as
soon as possible once the road is no longer
covered with snow.
R The use of snow chains may be restricted
by local regulations. Observe the relevant
regulations when mounting snow chains.
! Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may break, causing damage to
wheels, wheel arches or wheel suspension.
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions. If you intend to mount snow chains, please
bear the following points in mind:
R
You may not mount snow chains on all
wheel/tire combinations. When mounting
the snow chains, note the permissible tire
and snow chain dimensions.
R Mount snow chains only in pairs and only
to the rear wheels. Observe the
manufacturer's mounting instructions.
R Check the chain tension after driving
approximately 0.5 miles (1.0 km) .
i You can deactivate ASR when pulling
away with snow chains mounted.
(

Y page 49). This allows the wheels to spin
in a controlled manner, generating more
tractive force (friction effect). Tire pressure
Notes about tire pressure
G
Warning
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate

tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure. Tire pressure
255Wheels and tires Z

A table of recommended tire pressures can
be found on the Tire & Loading Information
placard
11
or the tire pressure plate on the
B-pillar on the driver's side of the vehicle
(Y page 256).
Use a tire pressure gauge intended for this
purpose. The outer
appearance of a tire does
not permit any reliable conclusion about the
tire pressure. On vehicles equipped with the
electronic tire pressure monitor, the tire
pressure can be checked using the on-board
computer. G
Warning!
If the tire pressure drops repeatedly:
R check the tires for foreign objects
R check whether the

wheel is losing air or the
valve is leaking
R make sure that only a valve cap approved
by the dealer listed on the inside of the
cover page is on the tire valve
Underinflated tires have a negative effect on
vehicle safety, which could lead you to cause
an accident.
Correct the tire pressure only when the tires
are cold. Tires are cold when the vehicle has
been parked for at least three hours or has
been driven less than 1 mile (1.6 km). Tire
temperature changes depending on the
ambient temperature, driving speed and tire
load. If the tire temperature changes by
18 ‡ (10 †), the tire pressure changes by
approximately 10 kPa (0.1 bar/1.5 psi). Take
this into consideration if you are checking tire
pressure when the tires are warm, and
correct the tire pressure only if it is too low
for 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
circumstances release the air in order to
adjust the pressure to the prescribed value
for cold tires. Tire pressure would then be too
low. Take note of the recommended tire pressure
data for cold tires on the Tire & Loading
Information placard
11
or the tire pressure
plate on the

B-pillar on the driver's side of the
vehicle.
i The data shown on the following tire data
labels are examples. Tire pressure data are
vehicle-specific and may deviate from the
data illustrated here. The tire pressure data
applicable to your vehicle can be found on
the Tire & Loading Information placard or
tire pressure plate of your vehicle. Tire & Loading Information placard
11 Tire pressure plate
You will find recommended tire pressure
specifications

tires and for a fully
loaded vehicle on the Tire & Loading
Information placard or on the tire pressure
plate. The tire pressure specifications apply
to the factory-mounted tires.

Wheels and tires

Maximum weight of the laden vehicle
The maximum weight is the sum of the
unladen weight of the vehicle, the weight of
the accessories, the maximum load and the
weight of the

optional equipment installed at
the factory. Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa is
equivalent to

1 psi. Another tire pressure unit
is bar. 100 kilopascal (kPa) is equivalent to
1 bar. Unladen weight
The weight of a vehicle with standard
equipment including the maximum filling
capacity of fuel, oil, and coolant. It also
includes the air-conditioning system and
optional equipment if these are installed on
the vehicle, but does not include passengers
or luggage. Maximum tire load
The maximum tire load in kilograms or
pounds is the maximum weight for which a
tire is approved. Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire. Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the

maximum axle load of one axle
by two. PSI (Pounds per square inch)
Standard unit of measurement for tire
pressure. Aspect ratio
Relationship between tire

height and width in
percent. Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's
surface. Tire pressure is specified in pounds
per square inch

(psi), in kilopascal (kPa) or in
bar. Tire pressure should only be corrected
when the tires are cold. For this, the vehicle
must have been stationary for at least three
hours or not have traveled more than 1.6 km
(1 mile) in this time. Tire tread
The part of the tire that comes into contact
with the road. Tire bead
The tire bead ensures that the tire sits
securely on the

wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim. Sidewall
The part of

the tire between the tread and the
tire bead. Weight of optional extras
The combined weight

of those optional extras
that weigh more than the replaced standard
part and more than 2.3 kilograms (5 lbs).
These optional extras, such as a roof rack or 270

characteristics could otherwise be
affected.
Otherwise, the operating reliability and road
safety of the vehicle could be jeopardized.
This could cause you to lose control of your
vehicle, resulting in an accident and injuring
yourself or others.
The vehicle tires
are an essential component
in the overall performance and stability of the
vehicle. The service life of tires is dependent
upon and proportional to tire type, speed
rating, environmental conditions, tire load,
tire pressure, road quality and individual
driving style.
For this reason, we recommend regularly
checking wear and correct tire pressure as
well as – according to the appropriate tire
configuration of the vehicle – regularly
rotating the tires.
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3000 to 6000 miles
(5000 to 10000 km), or earlier if tire wear
requires. Do not change the direction of
rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressures.
! If your vehicle is equipped with the tire
pressure monitor, each wheel has an
electronic component.
Tire-mounting tools should not be applied
in the area of the valve. Otherwise, the
electronic components could be damaged. Only have the tires changed at a qualified
specialist workshop, e.g. an authorized
Sprinter Dealer.
Diagram for rotating single tires and twin tires
Single tires
If the tires have identical dimensions, you
may rotate
the

tires at the front and rear axles
in pairs so that the tires' original direction of
rotation remains the same. On unidirectional
tires, an arrow on the sidewall shows the
prescribed direction of rotation of the tire.
Twin rear tires If the tires have identical dimensions, you
may rotate the tires at the front axle and the
inner wheels at the rear axle in pairs so that
the tires' original direction of rotation
remains the same. With nondirectional tires,
you may
rotate

the outside wheels at the rear
axle sideways.
Information on changing wheels
(Y page 229). Direction of rotation
Tires with a specified direction of rotation
have
additional benefits,

e.g. if there is a risk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tire indicates
its correct direction of rotation. 272

We test genuine parts, conversion parts and
accessories that have been specifically
approved for the type of vehicle for:
R reliability
R safety
R suitability
Despite ongoing market research, we are
unable to assess other parts. We therefore
accept no responsibility for the use of such
parts in Sprinters, even if they have been
independently or officially approved.
In Germany and

some other countries, certain
parts are only officially approved for
installation or modification if they comply
with legal requirements. All genuine Sprinter
parts satisfy these requirements.
Make sure that any replacement parts are
suitable for your vehicle. In many countries,
parts which result in a modification to the
vehicle could invalidate the vehicle's general
operating permit.
This is the case if:
R they cause a change to the vehicle type
from that for which the vehicle's general
operating permit was granted.
R other road users could be endangered.
R emission or noise levels are adversely
affected. The use of non-approved parts could affect
your vehicle's
operating

safety. We therefore
recommend that you use genuine Sprinter
parts, conversion parts and accessories that
have been approved for the type of vehicle.
0040Environmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited
Warranty applies as for new parts.
Genuine Sprinter parts, approved conversion
parts and accessories are available from an
authorized Sprinter Dealer. Here you will
receive advice about permissible technical
modifications, and the parts will be
professionally installed.
