176 Driving tips<br />
Driving and parking<br />
Always observe the maximum permissible<br />
speed specified for the M+S tires you have<br />
mounted.<br />
Once you have installed the winter tires:<br />
X Check the tire pressures (Y page 355).<br />
X Restart the tire pressure monitor<br />
(Y page 357).<br />
G Warning<br />
If you use your spare wheel when M+S tires<br />
are fitted on the other wheels, be aware that<br />
the difference in tire characteristics may very<br />
well impair turning stability and that overall<br />
driving stability may be reduced. Adapt your<br />
driving style accordingly.<br />
Have the spare wheel replaced by a regular<br />
road wheel with an M+S tire at the nearest<br />
authorized <strong>Mercedes</strong>-<strong>Benz</strong> Center.<br />
Snow chains<br />
For safety reasons, <strong>Mercedes</strong>-<strong>Benz</strong><br />
recommends that you only use snow chains<br />
which have been specially approved for your<br />
vehicle by <strong>Mercedes</strong>-<strong>Benz</strong>, or are of a<br />
corresponding standard of quality.<br />
! On vehicles with AIRMATIC, you must<br />
drive at raised vehicle level if snow chains<br />
have been mounted. The vehicle may<br />
otherwise be damaged.<br />
! There is not enough space for snow<br />
chains on some wheel sizes. Observe the<br />
information under "Tires and wheels" in the<br />
"Technical Data" section to avoid damage<br />
to the vehicle or the wheels.<br />
ROnly use snow chains when driving on an<br />
area completely covered by snow. Do not<br />
exceed the maximum permissible speed of<br />
30 mph (50 km/h). Remove the snow<br />
chains as soon as possible when you are no<br />
longer driving on snow-covered roads.<br />
RLocal regulations may restrict the use of<br />
snow chains. Applicable regulations must<br />
be observed if you wish to mount snow<br />
chains.<br />
RSnow chains must not be mounted on<br />
emergency spare wheels.<br />
If you intend to mount snow chains, please<br />
bear the following points in mind:<br />
Ryou may not attach snow chains to all<br />
wheel-tire combinations; see the "Tires and<br />
wheels" section in the "Technical data"<br />
chapter.<br />
Rmount snow chains only in pairs and only<br />
on the rear wheels. Observe the<br />
manufacturer's installation instructions.<br />
! If snow chains are mounted on the front<br />
wheels, the snow chains could grind<br />
against the bodywork or components of the<br />
chassis. This could result in damage to the<br />
vehicle or the tires.<br />
! Vehicles with steel wheels<br />
If you wish to mount snow chains to steel<br />
wheels, make sure that you remove the<br />
respective wheels' hubcaps first. The<br />
hubcaps may otherwise be damaged.<br />
i You may wish to deactivate<br />
ESP ® (Y page 67) when pulling away with<br />
snow chains installed. This way you can<br />
allow the wheels to spin in a controlled<br />
manner, achieving an increased driving<br />
force (cutting action).<br />
Slippery road surfaces<br />
G Warning<br />
If the vehicle becomes stuck in snow, make<br />
sure snow is kept clear of the exhaust pipe<br />
and from around the vehicle with the engine<br />
running. Otherwise, deadly carbon monoxide<br />
(CO) gases may enter vehicle interior<br />
resulting in unconsciousness and death.<br />
To assure sufficient fresh air ventilation, open<br />
a window slightly on the side of the vehicle<br />
not facing the wind.
