Winter tires
At temperatures below 45 °F (+7 °C), use winter tires or all-season tires. Both types of tire are identified by the M+S marking.
Only winter tires bearing the 
snowflake
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, 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.
WARNING
M+S tires with a tread depth of less than 1/6
inch (4 mm) must be replaced immediately.
They are no longer suitable for use in winter.
Always observe the maximum permissible speed specified for the M+S tires you have mounted.
Once you have mounted the winter tires:
•► Check the tire pressures.
•► Restart the tire pressure monitor
WARNING
If you use your spare wheel when M+S tires
are mounted on the other wheels, be aware
that the difference in tire characteristics
impairs cornering ability and reduces driving
stability. Adapt your driving style accordingly.
Have the spare wheel replaced by a normal wheel with an M+S tire at the nearest Mercedes-Benz Center.
