Snow chains
Safety notes
WARNING
If snow chains are fitted to unsuitable tyres, the
snow chains can come into contact with parts
of the vehicle. There is a risk of accident or ma‐
terial damage. Only fit snow chains on tyres
which have been approved by the manufacturer
as being suitable for snow chains.
WARNING
Insufficiently tensioned snow chains can dam‐
age tyres and vehicle components. There is a
risk of accident or material damage. Ensure that
snow chains are always adequately tensioned.
Re-tension them if necessary in accordance
with the snow chain manufacturer's instruc‐
tions.
Fine-link snow chains
The vehicle manufacturer recommends using
fine-link snow chains. Certain fine-link snow
chains have been tested, found safe for use in
traffic and rated as suitable by the manufacturer
of the vehicle.
Information regarding suitable snow chains is
available from a Service Partner of the manufac‐
turer or another qualified Service Partner or a
specialist workshop.
