Traction
Traction is the result of friction between the
tires and the road surface.
TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread is
level with the bars, the wear limit of 00CDin
(1.6 mm) has been reached.
Distribution of the vehicle occupants
The distribution of vehicle occupants over
designated seat positions in a vehicle.
Maximum permissible payload weight
Nominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Flat tire
General notes
Your vehicle is equipped with a spare wheel.
The spare wheel is under the vehicle at the
rear (Y page 313).
Information about fitting a wheel can be found
in the "Wheel change" section (Y page 308).
When you replace a tire, we recommend that
you also replace the tire valve. Please observe
the safety-relevant information on tire valve
(Y page 292). Changing wheels

WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec-
tronic components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes in the "Mounting a wheel" section
(Y page 308).
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 inter-
vals in the tire manufacturer's warranty book
in your vehicle documents. If no warranty
book is available, the tires should be rotated
every 3,000 to 6,000 miles (5,000 to
10,000 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 pressure and reac-
tivate the tire pressure monitor if necessary. Changing wheels

Genuine Sprinter parts
! Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrument cluster
R center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have aftermarket accessories installed at
a qualified specialist workshop. H
Environmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited War-
ranty applies as for new parts.
We test genuine Sprinter parts, as well as
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. If individual or
official approval is given, we assume no
responsibility for use in Sprinter vehicles.
In some countries, certain parts are only offi-
cially approved for installation or modification
if they comply with legal requirements. All
genuine Sprinter parts satisfy these require-
ments. Make sure that all parts are suitable
for your vehicle. All authorized Sprinter Dealers maintain a
supply of genuine Sprinter parts for required
service and repair work. Also, the strategi-
cally distributed parts delivery centers pro-
vide quick and reliable parts service.
Always specify the vehicle identification num-
ber (VIN) and engine number when ordering
genuine Sprinter parts (Y page 319). Vehicle electronics

WARNING
Always have work on the engine electronics
and related components carried out at a quali-
fied specialist workshop. Otherwise, the vehi-
cle's operating safety could be affected.
! Only have engine electronics and the cor-
responding parts, such as control units,
sensors or connector leads, serviced in a
qualified specialist workshop. Otherwise,
the vehicle parts may wear more quickly.
This can lead to loss of the New Vehicle

WARNING
You and others may damage your health due
to excessive electromagnetic radiation. By
using an external antenna, the possible health
risks of electromagnetic fields, which are
under discussion among the scientific com-
munity, should be largely prevented.
Therefore, only have the exterior antenna
installed at a qualified specialist workshop.
Electrical and electronic devices may have a
detrimental effect on both the comfort and
the operating safety of the vehicle. If equip-
