Snow chains
When driving with snow chains, always se-
lect the raised level of the level control sys-
tem AIRMATIC DC* (

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:
Use of 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.
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.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 76) before setting the vehicle
in motion. This will improve the vehi-
cle’s traction.
!Use of snow chains is not permissible
with tire size 245 / 45 R17
