On

please contactaqualified specialist workshop.
If you inten dto mount snowchains, please
bear thefollowing pointsinmind:
R Snow chains maynotbemounted onall

wheel-tire combinations(Ypage 318).
R Only usesnow chains whendriving onroads

R Local regulations mayrestrictthe use of
snow chains. Observe theappropriate regu-

R Do not exceed themaximum permissible
speed of30 mph (50km/ h).
R On vehicles withActive Body Control (ABC),
if snow chains havebeen installed, youmust
drive ataraised vehicle level(Ypage 168).
