Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 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 Snow chains should only be used on
the rear wheels. Follow the manufac-
turer'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.
ț Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.
i
When using snow chains, vehicles with
AIRMATIC should only be driven at
raised vehicle level (
୴ page 219). Vehi-
cles with ABC* should only be driven at
vehicle height 1 (
୴ page 221).

When driving with snow chains, you
may wish to deactivate the
ESP (
୴ page 80) before setting the ve-
hicle in motion. This will improve the
vehicle‘s traction.

use snow chains on rear tires only.
