The engine is equipped with a block heat-
er.

Snow chains
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 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.
Warning! G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.
i
When driving with snow chains, you
may wish to deactivate the ESP
(
୴ page 75) before setting the vehicle
in motion. This will improve the vehi-
cle‘s traction.
!
Use of snow chains is not permissible
with tire sizes 225/50 R16 and with
tire sizes 225/45 R17.
