Mercedes Benz 2009 M-Class User Manual

The engine is equipped with a block 
heater.

The electrical cable may be installed at an 
authorized Mercedes-Benz Light Truck 
Center.

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:

앫

Use of snow chains is not permissible 
with all wheel/tire combinations 
(

컄

page 536).

앫

Snow chains should only be used on 
the rear wheels. Follow the manufac-
turer’s mounting instructions.

앫

Only use snow chains that are 
approved by Mercedes-Benz. Your 
authorized Mercedes-Benz Light Truck 
Center will be glad to advise you on this 
subject.

앫

Use of snow chains may be prohibited 
depending on location. Always check 
local and state laws before installing 
snow chains.

앫

Do not use snow chains on the spare 
wheel (

컄

page 538).

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 Light Truck Center.
