Snow chains
When using snow chains, the vehicle
should only be driven at vehicle height 1
(page 191).
Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.Please observe the following guidelines
when using snow chains:
Using snow chains is not permissible
with all wheel/tire combinations.
Chains should only be used on the rear
wheels. Follow the manufacturer's
mounting instructions.
Use only snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 75) before setting the vehicle
in motion. This will improve the vehi-
cle‘s traction.
!Do not use snow chains with tire sizes
245 / 45 R18 on 8½J x 18 rim and
265 / 40 R18 in general (
page 331).
Do not use snow chains on tires mount-
ed on AMG rims.
