General notes

Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter.

Prior to the onset of winter, ensure that snow chains are stowed in the vehicle more. snow chains cannot be fitted on all wheel/tyre combinations. Observe the restrictions on the use of snow chains in the tyre pressure tables more.

Observe the notes in the "Changing a wheel" section more.

Driving with summer tyres

At temperatures below +7 corposwgl_2020.png , summer tyres lose elasticity and therefore traction and braking power. Change the tyres on your vehicle to M+S tyres. Using summer tyres at very cold temperatures could cause tears to form, thereby damaging the tyres permanently. Mercedes-Benz cannot accept responsibility for this type of damage.

WARNING

Wheel and tyre dimensions as well as the type of tyre can vary between the spare wheel and the wheel to be replaced. When the spare wheel is fitted, driving characteristics may be severely affected. There is a risk of an accident.

To prevent risks:

  • you should therefore adapt your driving style and drive carefully.

  • never fit more than one spare wheel that differs from the wheel to be replaced.

  • only use a spare wheel that differs from the wheel to be replaced for a short time.

  • have a spare wheel that differs from the wheel that has been changed replaced at the nearest qualified specialist workshop. You must observe the correct wheel and tyre dimensions as well as the wheel type.

WARNING

M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they do not provide sufficient traction. There is a risk of accident.

M+S tyres with a tread depth of less than 4 mm must be replaced.

At temperatures below +7 corposwgl_2020.png , use winter tyres or all-season tyres. Both types of tyre are identified by the M+S marking.

Only winter tyres bearing the mbsymb1_inv_0069.png snowflake symbol in addition to the M+S marking provide the best possible grip in wintry road conditions.

Only these tyres will allow driving safety systems such as ABS and ESP® to function optimally in winter. These tyres have been developed specifically for driving in snow.

Use M+S tyres of the same make and tread on all wheels to maintain safe handling characteristics.

Always observe the maximum permissible speed specified for the M+S tyres you have fitted.

If you fit M+S tyres that have a lower maximum permissible speed than that of the vehicle, affix a corresponding warning label in the driver's field of vision. You can obtain this at a qualified specialist workshop.

Under these circumstances, you should also restrict the maximum speed of the vehicle using permanent SPEEDTRONIC[1] so that it does not exceed the maximum permissible speed for the M+S tyres more.

Once you have fitted the winter tyres:

Check the tyre pressure more.

Reactivate the tyre pressure monitor more.

Snow chains

WARNING

If you drive too fast with snow chains fitted, they may snap. As a result, you could injure others and damage the vehicle. There is a risk of an accident.

Observe the maximum permissible speed for operation with snow chains.

When driving with snow chains fitted, do not exceed the maximum permissible speed of 50 km/h. Observe the country-specific laws and regulations for operation with snow chains.

Before fitting the snow chains, check them for damage. Damaged or worn snow chains may snap and damage the following components:

  • wheel

  • wheel housing

  • wheel suspension

Therefore, only use snow chains that are in perfect condition. Observe the manufacturer's installation instructions.

Vehicles with steel wheels: if you fit snow chains on steel wheels, you may damage the hub caps. Remove the hub caps from the relevant wheels before fitting the snow chains.

Snow chains offer better traction in wintry road conditions.

For safety reasons, Mercedes-Benz recommends that you only use snow chains that have been specially approved for your vehicle by Mercedes-Benz, or that are of a corresponding standard of quality. Information about snow chains can be obtained from any Mercedes-Benz Service Centre.

When fitting snow chains, please bear the following points in mind:

  • snow chains cannot be fitted on all wheel/tyre combinations. Observe the approved tyre and snow chain dimensions when fitting the snow chains. Observe the restrictions on the use of snow chains on the tyre pressure table more.

  • fit snow chains only in pairs and only to the rear wheels. Observe the manufacturer's installation instructions.

  • only use snow chains when the road surface is completely snow-covered. Remove the snow chains as soon as possible when you come to a road that is not snow-covered.

  • local regulations may restrict the use of snow chains. Observe the appropriate regulations before fitting snow chains.

  • when driving with snow chains fitted, do not exceed the maximum permissible speed of 50 km/h.

  • check the tension of the chains after a distance of approximately 1.0 km.

You may wish to deactivate ASR when pulling away with snow chains fitted more. This way you can allow the wheels to spin in a controlled manner, generating increased drive (cutting action).
