Snow chains
When driving with snow chains, always se-
lect the raised level of the level control sys-
tem AIRMATIC DC* (
୴ page 209). Other
settings may result in damage to your vehi-
cle.
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:
ț Use of snow chains is not permissible
with all wheel/tire combinations.
ț Chains should only be used on the rear
wheels. Follow the manufacturer's
mounting instructions.
ț Only use snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.

When driving with snow chains, you
may wish to deactivate the ESP

in motion. This will improve the vehi-
cle’s traction.
