Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
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 informa‐
tion.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷245/50 R 18.▷245/45 R 19.
Follow the chain manufacturer's instructions.
Make sure that the snow chains are always suf‐
ficiently 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 steer‐
ing of the Integral Active Steering is deactivated
automatically.
At speeds above the maximum permitted speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.
