Mercedes-Benz GL-Class: M+S tires - Winter operation - Wheels and tires - Mercedes-Benz GL-Class Owner's ManualMercedes-Benz GL-Class: M+S 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 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 
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 
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.
