Snow chains
Fine-link snow chains
The manufacturer of your vehicle recommends
use of fine-link snow chains. Certain types of

as road-safe and suitable.
Information regarding suitable snow chains is
available from a dealer’s service center or an‐
other qualified service center or repair shop.

WARNING
With the mounting of snow chains on un‐
suitable tires, the snow chains can come into
contact with vehicle parts. There is a risk of ac‐
cidents or risk of property damage. Only mount
snow chains on tires that are designated by
their manufacturer as suitable for the use of
snow chains.◀
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 snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Re-tighten as needed ac‐
cording to the snow chain manufacturer's in‐
structions.
Do not initialize the run-flat tires after mount‐
ing snow chains, as doing so may result in in‐
correct readings.
