If snow chains aremount edon the rear

to the vehicle bodyortochassis compon ents.
This could cause damage tothe vehicle orthe
tires. There isarisk ofan accident .
To avoid hazardous situations:
R never mount snowchains onthe rear
wheels
R only mount snowchains inpairs onthe

! On
some tiresizes there isnot enough space
for snow chains. Toavoid damage tothe vehi-

For safety reasons, Mercedes- Benzrecom-
mends thatyouonly usesnow chains thathave
been specially approved foryour vehicle by

If you inten dto mount snowchains, pleasebear
the following pointsinmind:
R Sno wchains maynotbemount edon all
