To avoid hazardous situations:
R never mount snowchains onthe rear
wheels
R only mount snowchains inpairs onthe

! On
some tiresizes there isnot enough
space forsnow chains. Toavoid damage to
the vehicle ortires, observe the"Wheel and
tire combin ations" sectionunder "Tiresand

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

If you inten dto mount snowchains, please
bear thefollowing pointsinmind:
R Sno wchains maynotbemount edon all
