If snow chains aremount edon the rear
wheels, thesnow chains couldcause abra-
sion tothe vehicle bodyortochassis com-
ponen ts.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 forsnow chains. Toavoid damage to
the vehicle ortires, observe the"Wheel and
tire combin ations" sectionunder "Tiresand
wheels".
For safety reasons, Mercedes- Benzrecom-
mends thatyouonly usesnow chains that
have 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, please
bear thefollowing pointsinmind:
R Sno wchains maynotbemount edon all
wheel/tire combinations.Permissible
wheel-tire combinations(Ypage 330).
R Only usesnow chains whendriving onroads
complet elycovered bysnow. Remove the
snow chains assoon aspossible whenyou
come toaroad thatisnot snow-c overed.
R Local regulations mayrestrictthe use of
snow chains. Observe theappropriate regu-
lations ifyou wish tomount snowchains. R
Do not exceed themaximum permissible
speed of30mph (50km/ h).
