For the sake of the environment
Summer tyres should be fitted again as soon as possible; they give better
handling on roads which are free of snow and ice. Summer tyres perform
with less rolling noise, tyre wear and – most important – reduce fuel con-
sumption.
Snow chains
Snow chains will improve vehicle handling on snow-covered
roads.
– Snow chains can be used on the front wheels only.
– Check that the snow chains are correctly seated after driving for
a few yards. Always take the manufacturer assembly instruc-
tions into account.
– Keep your speed below 50 km/h (30 mph).
– If there is a danger of being trapped despite having mounted
the chains, it is best to disable the driving wheels (ASR) in the
ESC ⇒ p age 184, Switching on/off the ESC and ASR.
Snow chains will improve braking ability as well as traction in winter condi-
tions.
For technical reasons snow chains may only be used with the following
wheel rim/tyre combination.
195/65 R15 Chains with links of maximum 15 mm
205/55 R16 Chains with links of maximum 15 mm
225/45 R17 Chains with links of maximum 9 mm
225/40 R18 Chains with links of maximum 9 mm
Safety First Operating instructions
Only use snow chains with fine-pitch links. The links must not protrude
more than 13.5 mm from the tyres (including tensioner).
Remove wheel covers and trim rings before fitting snow chains.
Remove the chains when roads are free of snow. Otherwise they will impair

handling, damage the tyres and wear out very quickly.
