decreases significantly when the tread
depth is less than
1 /

in (3 mm).
R
Replace the tires after six years at the
latest, regardless of wear. This also applies
to the spare wheel.
The service life of tires depends, among other
things, on the following factors:
R driving style
R tire pressure
R mileage
Winter operation
Please bear the following in mind
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center, at the onset of
winter.
Observe the notes in the "Changing a wheel"
section (
Y page 269).
Driving with summer tires
At temperatures below 45 ‡ (+7 †), the
elasticity of summer tires and therefore also
traction and braking capability are reduced
considerably — equip your vehicle with
M+S tires. Using summer tires at very cold
temperatures could cause tears to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage.
M+S tires
At temperatures below 45 ‡ (+7 †), use
winter tires or all-season tires. Both types of
tire are identified by the M+S marking.
Not all tires with the M+S marking provide the
driving characteristics of winter tires. In
addition to the M+S marking, winter tires also
bear the snowflake symbol i on the
sidewall. Tires with this marking fulfill the
requirements of the Rubber Manufacturers
Association (RMA) and the Rubber
Association of Canada (RAC) regarding snow
traction and were specially developed for
driving on snow. Only these tires will allow
driving safety systems such as ABS and
ESP
® to function optimally in winter, as these
tires have been designed specifically for
driving on snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.
i For further information on tires, see the
"Wheels and tires" section ( Y page 232).
G Warning
M+S tires with a tread depth of less than 1 /
6
inch (4 mm) must be replaced. They are no
longer suitable for winter operation.
Always observe the maximum permissible
speed specified for the M+S tires you have
installed.
When you have installed the M+S tires:
X Check the tire pressures ( Y page 249).
X Restart the tire pressure monitor
(
Y page 255).
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
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
which have been specially approved for your
vehicle by Mercedes-Benz, or are of a
corresponding standard of quality.
