Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains have been tested by the manufacturer of your vehicle, classified as road-safe and recommended.
Consult your service center for more information.
Use
Use only in pairs on the rear wheels, equipped with the tires of the following size:
▷ 225/55 R 17.
▷ 245/45 R 18.
Follow the chain manufacturer's instructions.
Make sure that the snow chains are always sufficiently tight. Retighten as needed according to the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after mounting snow chains, as doing so may result in incorrect readings.
Do not initialize the Tire Pressure Monitor after mounting snow chains, as doing so may result in incorrect readings.
When driving with snow chains, briefly activate Dynamic Traction Control if necessary.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when using snow chains.
Snow chain detection
The concept
When using snow chains, you should set whether you are driving with or without snow chains via the iDrive.
The snow chain detection system supports you by automatically showing the detected state on the Control Display.
When snow chains are in use, the rear axle steering of the Integral Active Steering is deactivated automatically.
At speeds above the maximum allowable speed with snow chains of 30 mph/50 km/h, the rear axle steering is activated again automatically.
Activating the status

If functioning properly:
▷ Snow chains are mounted. The setting is not
activated

After you drive a short distance, a Check Control message is shown and the state is activated automatically.
Confirm the automatic activation.
▷ Snow chains are not mounted. The setting
is activated
.
At speeds above 30 mph/50 km/h, a Check Control message is displayed. Deactivate the status manually.
If not functioning properly:
▷ Snow chains are mounted. The setting is not
activated

A Check Control message is not displayed.
The automatic detection system is malfunctioning.
