If snow chains aremount edon the rear
wheels, thesnow chains couldcause abrasion
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
fron twheels.
! On
some tiresizes there isnot enough space
for snow chains. Toavoid damage tothe vehi-
cle ortires, observe the"Wheel andtirecom-
bination s"sect ionunder "Tiresandwheels".
For safety reasons, Mercedes- Benzrecom-
mends thatyouonly usesnow chains thathave
been specially approved foryour vehicle by
Mercedes- Benz,or are ofacorr esponding
standard ofquality. Formore inform ation,
please contactaqualified specialist workshop.
If you inten dto mount snowchains, pleasebear
the following pointsinmind:
R Sno wchains maynotbemount edon all
wheel/tire combinations.Permissible wheel-
