Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 182).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 351).
X Restart the tyre pressure monitor
(Y page 355).
X Restart the tyre pressure loss warning system
(Y page 353).

G
WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is a risk of an accident.
To avoid hazardous situations:
R never fit snow chains on the front wheels
R fit snow chains to the rear wheels in pairs.
! You must drive at raised vehicle level if snow
chains have been fitted. The vehicle could
otherwise be damaged. Observe the informa-
tion in the "AIRMATIC package" section.
! When driving with snow chains fitted, do not
use the ADS sport mode (Adaptive Damping
System). The vehicle could otherwise be dam- aged.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have been specifically approved for your vehicle by
Mercedes-Benz, or that are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
If you intend to fit snow chains, please bear the
following points in mind:
R snow chains cannot be fitted to all wheel-tyre
combinations. Permissible wheel-tyre combi-
nations (Y page 361).
R only use snow chains if the road surface is
completely snow-covered. Remove the snow chains as soon as possible when you come to
a road that is not snow-covered.
R local regulations may restrict the use of snow
chains. Observe the appropriate regulations if you wish to fit snow chains.
R do not exceed the maximum permissible
speed of 50 km/h.
You may wish to deactivate ESP ®
when pulling
away with snow chains fitted (Y page 70). This
way you can allow the wheels to spin in a con-
trolled manner, achieving increased driving
force (cutting action).

Tyre pressure specifications
G
WARNING
Underinflated or overinflated tyres pose the
following risks:
R the tyres may burst, especially as the load
and vehicle speed increase.
R the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and check the tyre pressure of all the tyres includ-
ing the spare wheel:
R at least every two weeks
R when the load changes
R before embarking on a longer journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This Tyre pressure
