Winter driving
Snow chains
Snow chains should only be driven on 
snow-covered roads at speeds not higher 
than 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 
(
page 434).
Use snow chains in pairs and on rear 
wheels only. Follow the manufacturer’s 
mounting instructions.
Only use snow chains that are 
approved by Mercedes-Benz. Any 
authorized Mercedes-Benz Center will 
be glad to advise you on this subject.
Use of snow chains may be prohibited 
depending on location. Always check 
local and state laws before installing 
snow chains.
Do not use snow chains on the spare 
wheel (
page 439).
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.!Some tire sizes do not leave adequate clear-
ance for snow chains. To help avoid serious dam-
age to your vehicle or tires, make sure that the 
use of snow chains is permissible as specified in 
the “Technical data” section of this Operator’s 
Manual, see “Rims and tires” (
page 434).
!If snow chains are mounted to the front 
wheels, they may scrape against the body or axle 
components. The tires or the vehicle could be 
damaged as a result.
iWhen driving with snow chains, you may 
wish to deactivate the ESP® (page 88) before 
setting the vehicle in motion. This will improve 
the vehicle’s traction.
